Colorado Mined Land Reclamation Board Construction Material Rules and Regulations (a) Description of the method(s) of mining to be employed in each stage of the operation as related to any surface disturbance on affected lands, The permit area includes a significant deposit of sand and gravel located in the alluvium of the South Platte River in Weld County The site is located west of Highway 60, north of Weld County Road 40 5, and east and south of the South Platte River It encompasses 545 90 acres (plus or minus) and consists of four slurry wall lined pits, an unlined Siltation Pond, and two Fresh Water Ponds Site Preparation Initial disturbance on the property will be stnpping overburden from Fresh Water Pond 1 and the Siltation Pond to establish the plant footprint and construction of site berms Mining will then commence in these phases once the plant has been established During preparation of the Plant, Fresh 1/Vater Pond and Siltation Pond, roads will be established from the entrance to the plant area and to the office A scale with a scale house will be installed along the exit road in the plant area A drying and screening building will be constructed at the east end of the plant site in the initial phases of the mine The miner will utilize the existing buildings in the west of Cell 4 as the office until the point when mining progresses to the buildings Existing Structures The site is currently utilized as irrigated crop land, as such there is irrigation infrastructure located in the south freshwater pond, Cell 2, Cell 3, and Cell 4 that will need to be removed prior to mining There are existing farm buildings along the western edge of Cell 4 that will be utilized as the site offices These buildings will be removed prior to mining that side of Cell 4 during the later stages of the mine There is an access easement that bisects Cell 4 to service the farm buildings which is owned by the property owner and will be removed The office building structures located between the southern Fresh Water Pond and the Siltation Pond are planned to remain through the duration of the mine There are multiple oil and gas companies operating wells at the site that have facilities that will need to be removed prior to mining These facilities include O 2 PDC wells and gas lines in Cell 2 e 1 KPK well and tank battery west of Cell 4 O 1 PDC well and tank battery west of Cell 4 O 1 PDC well and tank battery located in the Plant Site The Miner is responsible for obtaining the necessary agreements for removal of these facilities prior to mining in the area M►ning Scrapers and/or bulldozers will strip the topsoil of any affected land poor to mining or stockpiling Topsoil will be segregated and stockpiled either in berms around the mine pits or in the processing area Topsoil stockpiles and berms that remain dormant for fourteen days Monarch DENM — Gravel Mine — MLRB 112 Permit Application Exhibit D -1 shall be roughened, mulched, or tackified to stabilize them Topsoil stockpiles that remain in place over 180 days will be seeded with the seed mixture described in the Reclamation Plan Overburden will then be stripped with scrapers and stockpiled in the processing area north of the plant Any excess material not needed for reclamation may be sold or hauled off -site during the life of the mine There will be no mining below the groundwater table until the slurry wall is complete, tested and approved for each slurry wall lined cell In order to mitigate mounding upgradient of the site two underdrains will be constructed prior to slurry wall construction on the southem end of Cell 1 and Cell 3 A mounding and shadow groundwater model will be performed prior to construction to inform the design and necessity of the underdrains The model will be provided to the Division when available If the model demonstrates that excessive mounding is not anticipated at the site, MMMA may apply for a Technical Revision to remove either or both of the underdrains from the Mine Plan Prior to starting construction of any slurry wall, the applicant shall apply for a Technical Revision with a slurry wall design and underdrain design report Each slurry wall lined phase will be dry -mined using scrapers, bulldozers, front-end loaders, excavators, or similar equipment The Fresh Water Pond and Siltation Pond will be unlined an wet mined with excavators For unlined cells, there will be no mining below the groundwater table until an approved Substitute Water Supply Plan(SWSP) has been obtained Mining at the site will progress in five major stages comprised of minor phases expected to last approximately 37 years A map depicting the phases can be found in Exhibit C-5 Processing The matenal will be wet screened and transported offsite by truck No crushing is planned at the site The processing area will be located on the north side of the siltation pond, east of Cell 4 Drying and Screening Building The building that houses the drying and screening operation will be on a reinforcd concrete pad that will be approximately 250' x 50' and located at the processing area Included with the building is a rotary dryer, baghouse, and 2 80 -foot -tall silos with a truck loading spout The entire footprint for the drying and screening operation is under 2 acres Import Material The Operator may import material from and export material to other sites The applicant is aware that in accordance with Rule 31 5(9) of the Construction Material Rules and Regulations, if any offsite material is used as backfill, a notarized letter will be submitted to the Division indicating the materials are inert The applicant will supply such a letter to the Division if, at the time of Reclamation, the applicant intends to use off -site material as backfill (6) Earthmoving, Topsoil will be stnpped with scrapers and/or bulldozers in the mining cells and stockpile areas and stockpiled in berms surrounding the pit for use in reclamation Overburden will then be Monarch DENM — Gravel Mine — MLRB 112 Permit Application Exhibit D - 2 stripped with scrapers and/or bulldozers and placed either in the stockpile to the north of Cell 2 or to the stockpile north of the plant Excavators, front-end loaders, and bulldozers will be used to excavate the material Haul trucks and conveyors will be utilized to transport the raw material from the active mine phase to the processing area See Exhibit C-5 for a cross-section of side -slope mining, the mine slope will be at a 3 horizontal to 1 vertical slope from the mine limit If needed, overburden, recovered silt or other suitable fill will be replaced to establish the final slope profile (c) All water diversions and impoundments, Storm water will be discharged per a CDPHE discharge permit There are no planned diversions or impoundments of existing water bodies A wash cycle for the aggregate processing area will be established using the freshwater pond as a source and the silt pond for return flow, with a pipe between the source pond and the return pond Any water consumed will be provided by the existing water rights associated with the property and/or a groundwater well with associated substitute water supply plan (see Exhibit G) (d) The size of area(s) to be worked at any one time Each phase is approximately 27-97 acres in size The Operator may mine multiple phases concurrently in order to obtain a range of material for production In addition to mining, the Operator, will begin reclaiming slopes as mining is finished in each stage Since multiple phases will be being worked at any one time, the approximate size of the areas to be worked at any one time will range from 25 acres to 120 acres and will depend on market conditions The Financial Warranty will be increased, as appropriate, to reflect all of the phases being mined at any time (e) An approximate timetable to describe the mining operation The timetable is for the purpose of establishing the relationship between mining and reclamation during the different phases of a mining operation The Operator anticipates that mining will commence as soon as all permits are in place The Operator anticipates extracting approximately 750,000 tons of aggregate in a typical year, up to 1,000,000 tons at peak capacity Production rate will vary based on market demands Timetable for Mining and Reclamation TIMETABLE ® Phase 1(Freshwater and Siltation Ponds) — 2 3 years ® Phase 2 (Cell 1) — 4 years ® Phase 3 (Cell 2) — 6 9 years ® Phase 4 (Cell 3) -13 2 years Monarch DENM — Gravel Mine — MLRB 112 Permit Application Exhibit D - 3 ® Phase 5 (Cell 4)— 10 6 years Total Protect — 37 years (I) Use Mining Plan Map in conjunction with narrative to present (i) Nature, depth and thickness of the deposit and thickness and type of overburden to be removed The deposit consists mainly of sand and gravel with some lenticular clay deposits The depth to bedrock ranges from 13 feet deep near the nver to 58 feet deep to the east side of the site Overburden is mainly sandy silt grading in to silty sand averaging approximately four feet in depth (u) Nature of the stratum immediately beneath the matenal to be mined in sedimentary deposits Bedrock consists mostly of soft bluish -grey claystone consistent with the Denver Formation (g) Identify the primary and secondary commodities to be m►ned/extracted and describe the intended use The primary commodities are sand, gravel and fill, intended for construction materials (h) Name and describe the intended use of all expected incidental products to be mined/extracted by the proposed operation Gold may be extracted as an adjunct component of any wash equipment installed at the site (i) Specify if explosives will be used in conjunction with the mining (or reclamation) No explosive material will be used on -site 6) Specify the dimensions of any existing or proposed roads that will be used for the mining operation Describe any improvements necessary on existing roads and the specifications to be used in the construction of new roads New or improved roads must be included as part of the affected lands and permitted acreage Affected land shall not include off -site roads which existed prior to the date on which notice was given or permit application was made to the office and which were constructed for purposes unrelated to the proposed mining operation and which will not be substantially upgrades to support the mining operation Describe any assocated drainage and runoff conveyance structures to include sufficient information to evaluate structure sizing The affected land and permitted acreage is inclusive of over one and one-half miles of land directly abutting public roadways, there is no need for any additional driveways, and on -site Monarch DENM— — Gravel Mine — MLRB 112 Permit Application Exhibit D - 4 haul roads will be incidental to mining areas depicted on the Mining Plan Map No roadways are affected by the mining operation other than access roads within the permit boundary and existing public roads to the site The Operator will apply for a Weld County Access Permit for the site Monarch DENM— — Gravel Mine — MLRB 112 Permit Application Exhibit D - 5 EXHIBIT; E EXHIBIT E - RECLAMATION PLAN This information provided in this Exhibit is intended to satisfy the requirements outlined in Section 6 4 5 of the Colorado Mined Land Reclamation Board Construction Material Rules and Regulations The proposed mining and reclamation plan focuses on minimizing the ecological impacts of mining, minimizing the length of time of impact, and maximizing long-term benefits (a) A description of the type(s) of reclamation the Operator proposes to achieve in the reclamation of the affected land, why each was chosen, the amount of acreage accorded to each, and a general discussion of methods of reclamation as related to the mechanics of earthmoving, The malonty of the site (Cell 1 through Cell 4) will be reclaimed to lined water storage reservoirs due to a need within the county and state for water storage facilities The mined area in the Siltation Pond and Fresh Water Pond maybe backfilled back to native grade and used as farmland or may be converted to a water storage facility if economically feasible and sufficient void space exists at the completion of mining Refer to Exhibit F for the acreages of each cell and additional details Earthmovinq Topsoil mined while establishing the plant sites and establishing the Fresh Water Pond and Siltation Pond will be placed in a berm along the edge of the pit The bermed topsoil will be used in final reclamation of the siltation pond and freshwater pond Any excess topsoil will be place to the north of the plant site(See Figure C-5) Topsoil mined in later phases will be placed in berms around the current mine phase or placed in the topsoil stockpiles to the north of the plant site or north of Cell 2 Topsoil from these stockpiles will be used to reclaim vegetated areas over the rest of the site Topsoil may be replaced by a scraper or haul truck, excavator, and bulldozer, and will generally be graded with a blade All grading will be done in a manner that controls erosion and siltation of the affected lands, to protect areas outside the affected land from slides and other damage Reclamation in each phase will begin as soon as mining in that phase is completed Overburden and clay seam matenals will be removed from mining phases and stockpiled north of Cell 2 and adjacent to the Freshwater Pond and Siltation Pond(See Figure C-5) Overburden and clay materials may also be sold as general fill to remove excess material not needed in Reclamation All disturbed areas will be regraded and smoothed to a finished grade that is suitable for revegetation or the final land use (b) A comparison of the proposed post -mining land use to other land uses in the vicinity and to adopted state and local land use plans and programs The water storage reservoirs will be compatible with the other land uses in the vicinity, which includes farmland, industrial land, and rural residential Municipal boundaries have Monarch-DENM — Gravel Mine — MLRB 112 Permit Application Exhibit E -1 approached the vicinity of the site and represent a growing need for both construction materials and water storage facilities (c) A description of how the Reclamation Plan will be implemented to meet each applicable requirement of Section 31 The Operator will carry reclamation to completion with reasonable diligence Each phase of reclamation will be generally completed within one to two years from completion of mining, but not more than five years from the date the Operator informs the Board or Office that final reclamation has commenced Section 3.1.5 Reclamation Measures Material Handling Grading will be performed to help control erosion and siltation of the affected lands through phased mining, implementing good operation techniques to handle material as little as possible, and vegetation of stockpiles remaining in place for more than 180 days Although the use of erosion protection devices is not anticipated, if deemed necessary by the operator at the time of excavation, silt fence, haybale dams or other erosion control devices will be installed Backfilling and grading will be completed as soon as feasible after the mining process is complete for each phase Maximum slopes and slope combinations will be compatible with the configuration of surrounding conditions and selected land use Mining will occur at a 31 slope Reclaimed slopes in the water storage reservoir will not be steeper than a 31 ratio and will be shaped by a bulldozer to remove rills caused by precipitation Any gaps in the slope will be filled with fill materials and construction methods that will insure stability The upland area will be reclaimed to grades consistent with pre -mining drainage patterns The operator will backfill using fill material generated on -site, or imported inert fill generated outside the permit area If any inert off -site material is used as backfill, a notarized letter will be submitted to the Division as required by Section 31 5(9) of the MLRB Construction Material Rules and Regulations It is not anticipated that mining will uncover any refuse or acid-forming or toxic producing materials, however if any such materials are encountered the operator will take precaution to handle the materials in a manner that will control unsightliness and protect the drainage system Drill or auger holes that are part of the mining operation shall be plugged with non- combustible material, which shall prevent harmful or polluting drainage Any test pits, soils boring holes, or monitoring wells not located within the mine excavation limits will be plugged as soon as it can be confirmed that they are no longer needed for the operation Mined material to be disposed of within the affected area will be handled in such a manner to prevent any unauthorized release of pollutants to the surface drainage system No unauthorized release of pollutants to groundwater shall occur from any materials mined, handled or disposed of within the permit area Monarch-DENM — Gravel Mine — MLRB 112 Permit Application Exhibit E - 2 Section 31.6 Water -General Requirements The Operator will comply_with applicable Colorado water laws governing injury to existing water rights and with applicable state and federal water quality and dredge and fill laws and regulations The operator will develop and comply with a stormwater" management plan and will use best management practices (BMPs) to ensure groundwater and surface water are protected to the greatest possible extent BMPs include schedules of activities,

Water needs estimated below provide for sustained production as detailed in the Mining Plan The Operator will adjust water supplies to account for actual demand, avoid waste, and continuously comply with laws and regulations of the Division of Water Resources and any other water agency having jurisdiction over the operation Projected Use And Consumption Annual evaporative depletions will be the evaporation from up to 5000 feet of 4 -foot wide de -watering trench, located inside of the slurry wall The total area of exposed water is 0 5 acres The gross annual evaporation at the Monarch DENM Mine is 42 inches according to NOAA Technical Report NWS 33, Evaporation Atlas for the Contiguous 48 United States Monthly evaporative losses are determined using percentages specified by the State Engineer's Office for locations below 6,300 feet The nearest weather station is in Longmont where the average annual precipitation is 15 08 Effective precipitation, that part of historical precipitation which was consumed by native vegetation on land to be covered by water surface, is conservatively estimated to be 70 MONARCH DENM — Gravel Mine — MLRB 112 Permit Application Exhibit G -1 percent of the total precipitation The annual average effective precipitation at the property is estimated to be 9 09 inches When subtracting the effective precipitation from the gross evaporation yields, the net annual evaporation is 31 44 inches, or 2 68 acre-feet per acre The Fresh Water Pond 1(FWP 1) is approximately 12 9 acres and the Siltation Pond will be utilized in 10 acre stages The approximate acreage of open water surface is 22 9 acres The annual amount of evaporation from open water surfaces is 62 7 acre-feet The second Fresh Water Pond will not be utilized at the same time as Fresh Water Pond 1 and it is slightly smaller than FWP 1(approximately 10 acres) Mining Production & Operations The Operator expects to extract approximately 500,000 tons annually of aggregate material from the site All water retained in the recovered material will be replaced pursuant to the Substitute Water Supply Plan (SWSP) The total annual amount of water retained in the gravel product from mining activities totals approximately 6 8 acre-feet The SWSP is renewed annually and will reflect analysis of production and depletion anticipated in each year of operation In addition, an estimated 4 0 acre-feet of water per year will be used for dust control based (approximately) on 5,900 gallons per day for 5 days a week for 10 months Annually the total evaporative and operational losses from mining activities (open water surface evaporation, water retained in the aggregate product, dust suppression) totals 73 5 acre-feet of depletion which must be augmented All depletions were lagged to the South Platte River using the lagging factors approved by the State Engineer pursuant to on -going Substitute Water Supply (SWSP) approvals (e) Indicate the projected amounts of the water sources to supply project water requirements Replacement Water The Miner will obtain an approved Substitute Water Supply Plan from the State Engineers office every year, providing annually or more frequently the opportunity to review the sufficiency of water supplies The SWSP approvals require that the applicant provide a detailed explanation of the mining operations, a quantification of all mining activities and subsequent depletions and all legally available replacement sources Water Sources Controlled by the Property Owners Western Mutual Ditch 24 shares (own) Western Mutual Ditch 3

Permit Application Exhibit G - 2 The Operator will apply for a CDPS(Colorado Discharge Permit System) permit from the Water Quality Control Division of the Colorado Department of Public Health and Environment poor to discharging water from the site MONARCH DENM — Gravel Mine — MLRB 112 Permit Application Exhibit G - 3 Groundwater Sampling and Analysis Plan This information provided in this subsection of Exhibit G is intended to satisfy the requirements outlined in the Groundwater Monitoring and Protection Technical Bulletin dated November 19, 2019 Existing Groundwater Conditions The near surface groundwater is part of an alluvial aquifer in which permeable sand and gravel alluvium overlies relatively impermeable bedrock of either the Fox Hills Sandstone and/or the Laramie Formation Groundwater, measured in 7 piezometers, occurs at depths usually ranging from 5 to 26 feet below surface with shallower groundwater to the north of the site The prevailing groundwater flow at the site is to the north reflecting the site topography Groundwater in the area is tributary to the South Platte River located northwest of the site Locally the groundwater levels and flow directions are likely influenced by > The South Platte River is northwest of the site For most of the year, the river likely acts as a drainage way maintaining groundwater levels at elevations greater than water elevations in the river In shorter periods of high run off, usually in the spring, river water levels will locally recharge the groundwater table ➢ The Western Mutual Ditch passes through the site between Cell 1 and Cell 2 The ditch may act like a drain during the non -irrigation season maintaining water levels at or above the water levels in the ditch During the irrigation season, the ditch may same as a source of recharge to the water table > The Farmers Independent Ditch traverses three quarters of a mile southeast of the site The ditch may act like a drain during the non -irrigation season maintaining water levels at or above the water levels in the ditch During the irrigation season, the ditch may serve as a source of recharge to the water table ➢ There are two irrigation ponds servicing the irrigation pivots at the site These ponds likely causes elevated groundwater levels at the south of the site during the irrigation season MONARCH DENM — Gravel Mine — MLRB 112 Permit Application Exhibit G - 4 > Irrigation The site is located in an area of irrigated cropland Applied irrigation that is not lost to evaporation and transpiration likely recharges the groundwater ➢ Alluvial wells Other than the seven monitoring wells drilled at the site for monitoring groundwater levels, there are also nineteen pumping wells permitted within 600 feet of the mine property There are seven wells north of the site, two wells east of the site, nine wells south of the site and one well west of the site If pumping, groundwater will be drawn to these wells Potential Slurry Wall and Mining Impacts to Local Groundwater Levels For all lined cells, a properly constructed slurry wall will tend to isolate these cells from the surrounding alluvial groundwater table The liner around these cells could cause "mounding" of groundwater (increase in groundwater elevation) on the upgradient side (south and southeast) of the lined cells and a potential "shadow effect" (reduction in groundwater level) on the downgradient side (north and northwest) of the mine Because the liner will tend to isolate these cells from the surrounding groundwater table, the effects of dewatenng when mining lined cells will tend to not extend beyond the liner Any mounding effect on the upgradient side of the site (south and southwest) is anticipated to be on the order of a few feet or less and will dissipate with distance from the mine Similarly, shadowing effects will be on the order of a few feet and will dissipate with distance from the mine The shadowing effects will be minimized by the presence of the South Platte River to the northwest and the Western Mutual Ditch that runs between Cells 5A and 5B and the Farmers Independent Ditch which runs southeast of the site Dewatenng of the unlined cells (Freshwater Pond 1, Freshwater Pond 2 and the Siltation Pond) will result in decreases in water levels around these cells Since there are no wells permitted within 600' of the unlined cells, the effects of dewatenng the unlined cells will be minimal Area Wells A review of the permitted wells on file with the State Engineer's Office (SEO), Division of Water Resources (DWR) indicates that there are forty one permitted pumping wells within 600 feet of the permit boundary All of these wells are screened in the alluvium None of these wells are within 600 feet of the unlined cells (Cells 1 and 2) The well locations and applicants are shown on Figure G-2 attached at the end of this section Groundwater Level Monitonnq and Mitigation Plan Dewatenng during mining of Cells 1 and 2 is unlikely to affect any wells in the area However, if the miner receives a complaint, the following mitigation plan will be implemented The site monitoring wells will be measured monthly to identify potential changes in alluvial groundwater flow or elevation associated with mining and reclamation activities Baseline data will be collected prior to dewatenng or construction of the slurry walls Baseline data will be collected from the monitoring program will provide a range of relative water levels associated with pre -mining groundwater conditions Experience MONARCH DENM — Gravel Mine — MLRB 112 Permit Application Exhibit G - 5 at other mines in similar geologic settings has found that groundwater levels tend to fluctuate being highest in the summer irrigation season and lowest in the winter and early spring If, during mining or reclamation, the relative seasonal groundwater elevation at any monitoring wells differs from baseline conditions by more than 2 feet, and the condition was not observed during baseline monitoring, or if the miner receives a complaint from any well owner within 600 feet of the site boundary, then the miner will evaluate the cause and take action within 7 days and notify the DRMS After the DRMS has been notified, the miner will review the data and available information and submit a report to the DRMS within 30 days The evaluation will include discussions with the well owner who has contacted the miner regarding a concern and review of baseline data from the well and vicinity to evaluate whether changes may be due to seasonal variations, climate, mining, slurry wall lining or other factors The report will identify the extent of potential or actual impacts associated with the changes If the extent of groundwater changes due to mining or reclamation activities is determined to be a significant contributing factor that has or may create adverse impacts, the mining associated impacts will be addressed to the satisfaction of the DRMS Miner will begin implementing one or more mitigation measures if mining and reclamation activity is determined to be a significant factor to groundwater changes requiring mitigation Mitigation measures may include, but are not limited to ➢ Placing water in a recharge pond to raise groundwater levels around the well ➢ Constructing a local clay liner at the edge of the mine Cell (i a between the dewatenng point and the well) in order to raise water levels on the well side of the liner and mitigate dewatenng effects ➢ Cleaning the well to improve efficiency ➢ Providing an alternative source of water or purchasing additional water to support historic well use in terms of water quantity and quality If needed, water quality parameters will be checked in affected wells to ensure alternative sources support historic use ➢ Modifying a well to operate under lower groundwater conditions This could include deepening the well or lowering pumps All work would be done at the miner's expense with the exception of replacing equipment that was non-functional poor to mining MONARCH DENM — Gravel Mine — MLRB 112 Permit Application Exhibit G - 6 Groundwater Quality Monitoring Plan Since mining operations at the site will take place inside of slurry wall lined cells, except for establishing the Freshwater Pond and Siltation Pond, it is unlikely that these operations will have a negative effect on groundwater quality To establish pre -mining groundwater quality for the site and to get coverage for each side of the site, the permittee will sample MW -1, MW -2, MW -4, and MW -6 To establish that mining has had no negative affect on water quality in the area, RMCC will sample the wells listed above annually during the month of November The water quality samples will be tested for the analytes listed in Tables 1 through 4 of "The Basic Standards for Ground Water," excluding the radiological section of Table 1 RMCC will notify DRMS within 7 days of receiving a lab report that indicates any of the standards set forth in Tables 1 through 4 have been exceeded If a lab report indicates an exceedance, a new sample will be taken to verify the exceedance and discount lab contamination Any water quality lab results will be included in the DRMS annual report for the site Annual groundwater testing will be conducted for the life of the mine unless the requirement has been reduced or eliminated through the Technical Revision process with the DRMS MONARCH DENM — Gravel Mine — MLRB 112 Permit Application Exhibit G - 7 Exhibit H - Wildlife Information Wildlife Assessment Site Description Savage and Savage biologists conducted an on -site wildlife assessment of the proposed HS Land and Cattle project site on January 19 and February 15, 2022 The project site is comprised of an approximately 790 acre site within portions of Sections 18 and 19, Township 4 North, Range 66 West, and portions of Sections 24, 25 and 26, Township 4 North, Range 67 West, all within the 6th PM, Weld County, Colorado The center of the project site is located at 40 297290° latitude and -104 820142° longitude The project site is located west of Gilcrest, Colorado, west of Colorado Highway 60, south and east of the South Platte River, and north of Weld County Road 40 The project site is accessed from any of the above roads Weather during the site investigation was cool, dry, and clear with a temperature in the mid -40's (°F) Snow cover was present on the agricultural areas of the secondary alluvial terrace The topography of the site is dominated by the primary and secondary alluvial terraces of the South Platte River The elevation of the center of the project area on the secondary alluvial terrace is 4753 feet and the elevation of the primary alluvial terrace is 4720 feet The project site is divided by a steep slope between the alluvial terraces that runs southwest -northeast along the west side of the project site The soils that dominate the site are formed from alluvium, with the predominant soils being sandy loams and loam that are underlain by aggregate with varying groundwater levels (USDA, 1981) The significant hydrologic feature adjacent to the site is the South Platte River The project site has been developed for non -irrigated and irrigated agriculture, oil and gas production, and grazing Agriculture within the project site is irrigated by pivot and flood irrigation methods Vegetation within the project site is divided largely between agricultural uses on the secondary alluvial terrace and grazing and non -irrigated hay production Interspersed with native riparian and wetland vegetation on the primary alluvial terrace Significant Wildlife Resources Tables 1, 2, and 3 list wildlife species that potentially occur on -site according to the Colorado Distribution Latilong Studies (CDOW, 1981, 1990, 1998) These latilong studies address mammals, birds, reptiles, and amphibians A further review of wildlife species for which the Colorado Division of Parks and Wildlife has distribution maps on the Colorado Oil and Gas Conservation Commission web site (http //cogcc state co us/infosys/Maps/wildlifemap cfm) was undertaken in January 2022 This mapping indicated the presence of a bald eagle nest to the west of the project site on the west side of the South Platte River Bald eagle winter night roosts are present along Exhibit H Page 1 the South Platte River to the southwest and northeast of the project site These features are depicted in Figure 1 The bald eagle nest west of the project site depicted on the COGCC mapping was not found during the on -site investigation Another bald eagle nest, not depicted on the COGCC mapping, was identified immediately outside the project site, near the northwest boundary An active great horned owl nest was also located within the project site immediately adjacent to Colorado Highway 60 north of Weld County Road 42 During the on -site investigation, the following wildlife species were observed, bald eagle, Canada geese, great horned owl, northern harrier, red -tail hawk, red -winged blackbirds, and black -tailed prairie dogs Seasonal Use The mammal species that potentially occur on -site are expected to be year -found residents or users of the site The carnivore and ungulate species are not restricted to this site and tend to have relatively large home ranges (up to several square miles) The majority of rodent and insectivore species can be expected to reside on -site throughout the year, though many may hibernate during the cold months Avian species may be year-round, temporary migrants, or summer residents of the site Year-round residents would include the waterfowl, raptors, gallinaceous birds, pigeons, owls, and woodpeckers The majority of the shorebirds and passerines would use the site during the spring, summer, and fall for feeding or resting during migration Amphibian and reptile species of the site are year- round residents Threatened and Endangered Species and Critical Habitat Potential habitat for the Preble's meadow jumping mouse was evaluated based on results of a search of potentially occurring threatened or endangered species on the U S Fish and Wildlife Service web site for Weld County Additionally, bald eagle (Haliaeetus leucocephalus) nest locations and winter night roost locales were evaluated from the Colorado Oil and Gas Conservation Commission (COGCC) web site map of sensitive wildlife habitat and restricted surface occupancy areas for protected wildlife species Additional protected eagle and owl nests were located within or adjacent to the project site and are discussed below Preble's meadow jumping mouse Potential habitat exists for the Preble's meadow jumping mouse within the project site along the South Platte River and within the adjacent riparian corridor, marsh, and wetland areas Exhibit H Page 2 The mouse has been trapped downstream from the project site along the South Platte River and northwest of the project site at the confluence of the Little and Big Thompson Rivers within Milliken, Colorado If project development will affect potential Preble's meadow jumping mouse habitat, the proponent will secure necessary clearances and permits from the U S Fish and Wildlife Service prior to disturbance of the potential habitat Bald Eagle Bald eagle nests identified adjacent to the project site have federal and state seasonal and distance restrictions when the nests are actively occupied by adults and young The seasonal restrictions are generally from November through the following July and distance restrictions vary from 'A to Y. mile from the active nest Specific seasonal and distance restrictions are determined on a case by case basis by the U S Fish and Wildlife Service As operational plans are finalized and the nature of the nests is determined (active or inactive), the proponent will consult with the U S Fish and Wildlife Service to determine any project specific distance and/or seasonal restrictions Great Horned Owl Great horned owls are protected under the federal Migratory Bird Treaty Act, and as such, activities that cause disturbance to nesting adults, young, and eggs are prohibited As the nest that was observed is located within an industrial business site and adjacent to Colorado Highway 60, the birds are already habituated to significant human activity No additional activities will be undertaken that would cause additional disturbance to the active owl nest Burrowing Owls Burrowing owls (Athene cunicularia), a species of concern in Colorado, occupy abandoned prairie dog holes on the outskirts of prairie dog colonies No abandoned prairie dog colonies were found within the project site, nor was evidence of burrowing owls observed Project Effects to Wildlife The HS Land and Cattle project site is proposed for aggregate material extraction and shipment to end users from the project site Noise and air emissions during mining will cause a temporary disturbance to wildlife Species such as raccoons, coyotes, deer, and raptors will continue to use the riparian corridor during mining operations and the site itself when operations are not active Bird species will use the periphery of the site and the site itself opportunistically, if prey or food species are present Exhibit H Page 3 The proposed project will extract aggregate and leave more varied topography within the site Permanent reclamation of the site will entail grading, respreading topsoil, and seeding and planting perennial species that will support wildlife The mining and reclamation will create a more diverse habitat than is currently present Any areas of open water will sustain additional species of reptiles and amphibians as well as shorebirds and waterfowl The addition of any water will create fringe environments favorable to predatory mammals and raptors, as well as food and water sources for herbivores With the planting of additional trees and shrubs, additional sti ata and vegetation layers will be added to the site, creating improved cover, foraging, roosting, and nesting areas foi wildlife Exhibit H Page

State agencies including the Agricultural Experiment Stations. and local participants Custom Soil Resource Report for Weld County, Colorado, Southern Part Monarch-DENM November 18. 2021 Preface Soil surveys contain information that affects land use planning in survey areas. They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists. urban planners, community officials, engineers, developers, builders, and home buyers. Also. conservationists, teachers, students, and specialists in recreation, waste disposal. and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State. and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local. and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey. the site for official soil survey information.

description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses Soil scientists observed the steepness, length, and shape of the slopes, the general pattern of drainage, the kinds of crops and native plants, and the kinds of bedrock They observed and described many soil profiles A soil profile is the sequence of natural layers, or horizons, in a soil The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down `to bedrock The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs) MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006) Soil survey areas typically consist of parts of one or more MLRA The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape Commonly, individual soils on the landscape merge into one another as their characteristics gradually change To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils They can observe only a limited number of soil profiles Nevertheless, these observations, supplemented by an understanding of the soil -vegetation -landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries Soil scientists recorded the characteristics of the soil profiles that they studied They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units) Taxonomic classes are concepts Each taxonomic class has a set of soil characteristics with precisely defined limits The classes are used as a basis for comparison to classify soils systematically Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile After the soil 5 Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research The objective of soil mapping is not to delineate pure map unit components, the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions Some components may be highly contrasting to the other components of the map unit The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas Soil scientists make many field observations in the process of producing a soil map The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist Observations are made to test and refine the soil -landscape model and predictions and to verify the classification of'the soils at specific locations Once the soil -landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components Properties of each soil typically vary from one point to another across the landscape Observations for map unit components are aggregated to develop ranges of characteristics for the components The aggregated values are presented Direct measurements do not exist for every property presented for every map unit component Values for some properties are estimated from combinations of other properties While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests Soil scientists interpret the data from these analyses and tests as well as the field -observed characteristics and the soil properties to determine the expected behavior of the soils under different uses Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs Data are assembled from other sources, such as research information, production records, and field experience of specialists For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity Soil conditions are predictable over long periods of time, but they are not predictable from year to year For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will - have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and 6 Custom Soil Resource Report identified each as a specific map unit Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols

descriptions, along with the maps, can be used to determine the composition and properties of a unit A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas A map unit is identified and named according to the taxonomic classification of the dominant soils Within a taxonomic class there are precisely defined limits for the properties of the soils On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes Consequently, every map unit is made 11 Custom Soil Resource Report up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management These are called noncontrasting, or similar, components They may or may not be mentioned in a particular map unit description Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management These are called contrasting, or dissimilar, components They generally are in small areas and could not be mapped separately because of the scale used Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into Iandforms or landform segments that have similar use and management requirements The delineation of such segments on the map provides sufficient information for the development of resource plans If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas An identifying symbol precedes the map unit name in the map unit descriptions Each description includes general facts about the unit and gives important soil properties and qualities Soils that have profiles that are almost alike make up a soil series Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use On the basis of such differences, a soil series is divided into soil phases Most of the areas shown on the detailed soil maps are phases of soil series The name of a soil phase commonly indicates a feature that affects use or management For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series Some map units are made up of two or more major soils or miscellaneous areas These map units are complexes, associations, or undifferentiated groups A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas Alpha -Beta complex, 0 to 6 percent slopes, is an example An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar Alpha -Beta association, 0 to 2 percent slopes, is an example 12 Custom Soil Resource Report An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them Alpha and Beta soils, 0 to 2 percent slopes, is an example Some surveys include miscellaneous areas Such areas have little or no soil material and support little or no vegetation Rock outcrop is an example 13 Custom Soil Resource Report Weld County, Colorado, Southern Part 1—Altvan loam, 0 to 1 percent slopes Map Unit Setting National map unit symbol 3611 Elevation

and plant ecologist conducted an on -site vegetation assessment of the proposed HS Land and Cattle project site on February 15, 2022 The project site is comprised of an approximately 790 acre site within portions of Sections 18 and 19, Township 4 North, Range 66 West, and portions of Sections 24, 25 and 26, Township 4 North, Range 67 West, all within the 6`h PM, Weld County, Colorado The center of the project site is located at 40 297290° latitude and -104 820142° longitude The project site is located west of Gilcrest, Colorado, west of Colorado Highway 60, south and east of the South Platte River, and north of Weld County Road 40 The project site is accessed from any of the above roads Weather during the site investigation was cool, dry, and clear with a temperature in the mid -40's (°F) Snow cover was present on the agricultural areas of the secondary alluvial terrace The topography of the site is dominated by the primary and secondary alluvial terraces of the South Platte River The elevation of the center of the project area on the secondary alluvial terrace is 4753 feet and the elevation of the primary alluvial terrace is 4720 feet The project site is divided by a steep slope between the alluvial terraces that runs southwest -northeast along the west side of the project site The soils that dominate the site are formed from alluvium, with the predominant soils being sandy loams and loam that are underlain by aggregate with varying groundwater levels (USDA, 1981) The significant hydrologic feature adjacent to the site is the South Platte River The project site has been developed for non -irrigated and irrigated agriculture, oil and gas production, and grazing Agriculture within the project site is irrigated by pivot and flood irrigation methods Overall, vegetation communities within the project site are divided largely between agricultural uses on the secondary alluvial terrace and grazing and non -irrigated hay production interspersed with native riparian and wetland vegetation on the primary alluvial terrace The vegetation community locations are depicted on Figure 1 Vegetation Communities Irrigated Agriculture Agricultural fields within the project area were in various states of production duiing the on -site evaluation The majority of the fields had been harvested for the season, and disked or tilled and left fallow, or replanted Fields were noted to have been planted to corn and milo during the 2021 season These crops have been harvested and the fields disked and tilled prior to anticipated planting Several irrigation tailwater ponds are located within the project area These ponds did not contain any native vegetation communities One irrigation canal and a number of secondary irrigation ditches traverse the project site None contain areas of native vegetation Exhibit 3 Page 1 Non -Irrigated Agriculture There are a number of small hayfields located on the primary alluvial terrace adjacent to the South Platte River within and adjacent to the riparian corridor and plains cottonwood woodland vegetation community These hayfields are subirrigated, as evidenced by adjacent native wetland plant species (cattails and coyote willows) and i elict alluvial features (potholes, and overflow channels) The vegetation from these hayfields appears to be a mix of planted and native species Agricultural Crop Yields The Natural Resource Conservation Service soil survey reports yields for common crops (1980) as follows for the Altvan, Aquolls, Ascalon, Bankard, Dacono, Olney, Otero, and Ustic Tornorthents map units, alfalfa hay (2 5-5 5 tons/acre), sugar beets (23-26 tons/acre), corn (50-180 bushels/acre), corn silage (33-35 tons/acre), dry pinto beans (2400-2700 pounds/acre), onions (525-550 sacks/acre), and potatoes (325-350 hundredweight/acre) Native Vegetation Communities Plains Cottonwood Woodland/Cattail Marsh/Coyote Willow Vegetation Association The primary alluvial terrace of the project site forms a southwest -northeast trending strip along the east bank of the South Platte River Within and adjacent to the project site the primary alluvial terrace varies from 1200 to 3200 feet in width Vegetation within the primary alluvial terrace is a complex mosaic of cottonwood woodland, cattail marsh, coyote willow wetland, and streambank graminoid wetland The plains cottonwood vegetation association is comprised of a mature plains cottonwood (Populus deltoides) overstory with a variable understory of shrubs and herbaceous forbs and graminoids Understory shrubs include snowberry (Symphoricarpos rotundifolrus), skunkbush (Rhus trilobata), chamisa (Chrysothamnus nauseosus), and coyote willow (Salix exidua) Understory graminoids and forbs include bromes (Bromus spp ), western wheatgrass (Agropyron smiths), bluegrasses (Poa spp), orchardgrass (Dactyl's glomerata), inland saltgrass (Distichlis spicata), lambsquarters (Chenopodium spp), sweetclovers (Meldotus spp), and milkweeds (Asclepias spp) This vegetation community is found predominantly on the higher and more mesic locations within the primary alluvial terrace Cattail marsh vegetation communities are distinct and dominated by dense, nearly impenetrable cattail (Typha latifolia) stands These stands are found in shallow swales and depressions within the primary alluvial terrace As cattails require standing water for the large part of the growing season, these stands are subirrigated or adjacent to flowing water Coyote willow stands are dense monotypic understory thickets of coyote willow These small stands are associated with wetlands and/or waterway banks As with the cattail marshes, they require subirrigation or flowing water and are therefore found in depressions, swales, and along waterways within the primary alluvial terrace of the project area Exhibit J Page 2 Xeric Shrubland The boundary between the primary alluvial terrace and the secondary alluvial terrace on the project site is a steep, thirty-foot high slope This slope contains a limited xeric shrubland vegetation community, adapted to the soil of the slope (Ustic Torriorthents, map unit 68) (USDA, 1981) Dominant plant species of this community include chamisa, cheatgrass (Bromus tectorum), and alkali sacaton (Sporobolus airoides) Vegetation cover is relatively sparse, accounting for between 25 and 45 percent vegetation cover Threatened and Endangered Species and Critical Habitat Potential habitat for the Ute ladies' -tresses orchid (Spiranthes diluvialis), the sole threatened or endangered plant species known in the area, is present within the project site Within the primary alluvial terrace there are subirrigated hay fields with native vegetation containing typical plant associates of the orchid The subirrigated hayfields, as well as any other subirrigated native meadow areas within the primary alluvial terrace constitute potential Ute ladies -tresses orchid habitat Prior to any disturbance of potential habitat, a pedestrian survey for the orchid during the flowering period of a local type population should be conducted Results of the survey will be reported to the U S Fish and Wildlife Service and

PERMANENT MAN-MADE STRUCTURES The information provided in this Exhibit is intended to satisfy the requirements outlined in Section 6 419 of the Colorado Mined Land Reclamation Board Construction Material Rules and Regulations Where mining will adversely affect the stability of any significant, valuable or permanent man-made structure located within 200 feet of affected land, the applicant may either: a) Provide a notarized agreement between the applicant and the person(s) having an interest in the structure, that the applicant is to provide compensation for any damage to the structure, or b) The applicant shall provide an appropriate engineering evaluation that demonstrates that such structure shall not be damaged by activities occurnng at the mining operation' or c) Where the structure is a utility, the Applicant may supply a notarized letter stating that the mining and reclamation as proposed will have no negative effect on their utility The known, permanent, man-made structures within 200 feet of the proposed mine areas are listed on Exhibit C-3 Please refer to the attached engineering stability analysis that shows that structures shall not be damaged by activities occurnng at the mining operation Monarch-DENM Gravel Mine — DRMS 112 Permit Application Exhibit S -1 February 22, 2022 Mr Eric Leigh Monarch Mountain Minerals and Aggregates, LLC 5 Concourse Parkway, Suite 1900 Atlanta, GA 30328 Re Stability Analysis, Monarch-Denm Gravel Mine, West of Gilcrest, Weld County, Colorado Dear Mr Leigh This letter has been prepared to address the Mined Land Reclamation Board (MLRB) Construction Materials Rule 6, Section 4, Subsection 19, Exhibit S - Permanent Man -Made Structures (6 419, Exhibit S) for the proposed Monarch- Denm Gravel Mme located west of State Highway 60 near the intersections of the highway and Weld County Roads 42 and 44 in Weld County, Colorado This letter describes the project and slope stability analyses utilized to evaluate the distance between the edge of mining and adjacent structures to avoid damage to the structure The site is located approximately 1 6 miles west of the town of Gilcrest More specifically, the site occupies most of the Northwest Quarter of Section 30, most of the East Half of Section 19, and minimal parts of the West Half of Section 19, Township 4 North, Range 66 West of the 6th Principal Meridian The mine is in an area of irrigated agricultural land with common oil and gas wells and related infrastructure The Monarch-Denm mine will consist of seven (7) mine areas Three (3) of the mine areas will be unlined and four (4) of the mine areas will be lined with slurry walls The three (3) unlined mine areas will be located along Highway 60 and will serve as sources of water with one of the areas backfilled with silt The four (4) lined areas, will be located further to the west and are herein referred to as Cells 1 through 4 These four (4) cells will be reclaimed as lined ponds All of the cells will be mined at slopes of 3 horizontal to 1 vertical (3h 1v) Based on the stability analyses, this report indicates that the setbacks and perimeter slopes in the mining plan are sufficient to protect structures within 200 feet of the permitted mining boundary Actual setbacks may be greater due to permit limitations, zoning requirements, construction issues, agreements with owners, and extent of economically mineable aggregate or other issues GEOLOGY The Site is located approximately 20 miles east of the eastern flank of the Rocky Mountain Front Range Younger sedimentary strata dip eastward off the Pre -Cambrian igneous and metamorphic rocks that form the core of the Front Range into the Denver Structural Basin The Denver Basin is an asymmetrical downwarp of sedimentary strata with a steeply dipping west limb and a gently dipping east limb Bedrock does not crop out at the site, however regional geologic mapping of the area (Colton, 1978) indicates the near surface bedrock beneath the site is most likely the Laramie Formation and/or the Fox Hills Sandstone Colton (1978) describes the Laramie as mostly claystone, shale, sandy shale, and lenticular sandstone The Lower Laramie is described as sandstone, sandy shale, and claystone with several coal beds Colton (1978) describes the Fox Hills Sandstone as a cross bedded sandstone that grades to a silty sandstone and silty shale The regional mapping indicates the bedrock is overlain by the Broadway Alluvium Colton (1978) describes the Broadway as sand and gravel deposited by the South Platte River and its tributaries that is terraced typically lying about 40 feet above major streams Along the South Platte River, the Broadway is typically on the order of 35 feet thick but can range up to 125 feet thick GEOTECHNICAL CONDITIONS Monarch drilled approximately twenty-seven (27) borings at the site An Xcel spreadsheet was provided to us summarizing the materials encountered in the borings Mr Eric Leigh February 22, 2022 Page 2 Based on the site investigations summarized in the spreadsheet, the natural site stratigraphy generally consists of three (3) main units 1) Overburden generally consisting of near surface fine to medium grained clayey sand that locally grades to a silty or sandy clay, 2) Sand and Gravel alluvial deposits that underlie the overburden and overlie the bedrock, and 3) bedrock usually consisting of sandy claystone that is commonly weathered in the top 1 foot Overburden The overburden is typically a fine to medium grained clayey sand that locally grades to silty or sandy clay typically ranging from approximately one (1) to seven (7) feet in thickness This unit is usually slightly moist to moist with the top 6 to 8 inches containing significant organics Sand & Gravel The sand and gravel is present throughout the site underlying the overburden and overlying the bedrock This unit typically consists of slightly silty, fine to medium grained sand locally grading to a fine to coarse grained sand and/or gravelly sand This unit ranges in thickness from approximately thirty-eight (38) to fifty-seven (57) feet Bedrock The bedrock encountered in the exploratory borings was generally weathered in the upper foot typically became harder in unweathered zones The bedrock consisted of sandy claystone Groundwater Groundwater was encountered in all of the borings at approximately six (6) to thirty (30) feet below ground surface The groundwater levels will vary seasonally and will typically rise during the irrigation season and when recharge is applied Groundwater will be controlled in the four (4) lined cells with the proposed below grade slurry wall and by pumping down the water level on the interior of the slurry wall After slurry wall construction, groundwater mounding is anticipated on the upgradient (south and east) side of the site and a groundwater shadow (deeper water table) is anticipated on the downgradient (north and west) side the site At the unlined mine areas, dewatenng from perimeter trenches will be practiced when mining below the water table From a geotechnical standpoint, the sand and gravel will form the majority of the mine slopes These soils are generally strong and stable, particularly when dewatered STRUCTURES WITH 200 FEET OF DISTURBED AREAS The known, permanent, man-made structures within 200

stability analyses of neighbonng structures The draft summarizes adequate factors of safety (FOS) for non -critical and critical structures The structures around the Monarch-Denm mine are, for the most part, considered critical structures The FOS are for both static and seismic (from an earthquake) stability analyses For generalized strength assumptions and critical structures, an FOS of 1 5 is considered sufficient for static conditions and an FOS of 1 3 is considered suitable for seismic conditions The stability of structures within 200 feet of the proposed mining limits was evaluated at five (5) representative sections under anticipated loading conditions around the perimeter of the site as discussed below The Galena computer program was used for the analysis The method for selecting the critical failure surface for each analyzed loading condition was the following The Modified Bishop's Method of Analysis was used to find the critical failure surface by randomly searching 20,001 trial failure circles over a broad range of the slope surface and at the structure in question to evaluate the lowest factor of safety Both static stability under anticipated mining conditions and seismic stability under peak ground acceleration loads were performed Seismic loading was obtained from the U S G S Unified Hazard Tool attached to this report Review of the Hazard Tool indicated a maximum horizontal acceleration of 0 083g with a return period of 2,475 years for the site The five (5) cross section locations were selected and analyzed as described below ► Section A This section

the bottom of the excavation Groundwater was modeled at a depth of 20 feet exterior to the slurry wall MATERIAL PROPERTIES The material index and engineering strengths assumed in this slope stability report are discussed below Overburden and Mud Lens The strength properties for the in situ silty to clayey sand overburden were based on our engineering judgment, the following parameters have been used to model the overburden Unit Weight (pct) Cohesion C' psf Friction Angle V° 114 50 29 Alluvial Sand and Gravel The sand and gravel is generally a fine to medium -grained sand overlying a fine to coarse grained sand that is typically medium dense and locally gravelly The alluvial sand and gravel unit was modeled as follows Unit Weight (pcf) Cohesion C' psf Fnct►on Angle (P'° 129 35 Bedrock Bedrock below the alluvium is sandy claystone, sandstone and interdaminated to interbedded claystone and sandstone bedrock Sandstone is typically stronger than claystone Sandy Claystone is generally a weak bedrock To be conservative, we modeled the bedrock as sandy claystone For the sandy claystone bedrock, two potential strength conditions were considered These strength conditions are referred to as 1) peak strength, and 2) residual strength Mr Eric Leigh February 22, 2022 Page 5 Peak strength is the maximum shear strength the sandy claystone bedrock exhibits The shear strength is made up of both cohesion (diagenetic bonding) and internal friction Under short-term conditions for unsheared sandy claystone, peak strength govems behavior If a sheared surface or sheared zone is present within sandy claystone because of faulting, slippage between beds due to folding, past shrink -swell behavior, stress relief, weathering, or from a landslide, the cohesion along the sheared surface is reduced to zero, and the angle of internal faction is decreased, due to alignment of clay minerals parallel to the shear plane Under these conditions a sandy claystone exhibits its lowest strength known as residual strength Residual strength bedrock occurs in discrete zones, parallel with the sheared surface or zone, whereas fully softened strength occurs over a broader area (not used in this modeling) Based on data from site investigations, the residual strength sandy claystone was modeled in a one (1) foot thick, weathered layer overlying the peak strength bedrock as follows Unit Weight (pct) Cohesion C' psf Friction Angle �' ° Peak =135 Peak =100 Peak = 28 Residual =130 Residual = 0 Residual =18 Soil-Bentonite Slurry Wall ' The proposed slurry wall will consist of a mix of the overburden clayey to silty sand, alluvial sand, and imported bentonite The resulting mix will produce a non -Newtonian fluid with some shear strength characteristics based on a reduced friction angle of the overlying overburden Based on engineering judgment, we modeled the slurry wall as follows Unit Weight (pcfl Cohesion C' psf Fnction Angle V ° 115 0 0 STABILITY ANALYSES RESULTS The stability analyses assumed the mining will be per the mine plan The plan includes mining at 3h lv slopes, wewatering with perimeter trenches in the unlined cells, and dewatenng of trapped water left after slurry wall construction in the lined cells Setbacks listed in Table 1 (below) indicate the setback from the structure to the mining limits The setback distance can be increased as needed to address other restrictions The factor of safety shown below is the minimum factor of safety of the conditions listed above Mr. Eric Leigh February 22, 2022 Page 6 TABLE 1 - SLOPE STABILITY RESULTS AND

Factors of Safety listed in the table above, the mine will not be a hazard to neighboring structures provided the structure and slurry wall offsets, as well as the perimeter mine slopes, follow the mine plan. LIMITATIONS Our review is based on regional geologic mapping. present mining plans, and in part borehole data by others. Stability analyses were performed using typical strength parameters for the various strata in the critical sections. Should the mining plans change or subsurface conditions vary from those portrayed in this letter, we should be contacted in order to re-evaluate the potential affects on permanent man-made structures. Stability analyses were run at the structure or property line in question and were not run on failure surfaces closer to the highwall. Note also that surcharge loads due to temporary material stockpiles and overburden berms were not considered in the analysis. Please call with any questions or comments. Sincerely, Civil Resources.

A search of our database indicates that no properties of historical significance included or nominated for inclusion in the state register have been recorded within the proposed permit area. Please, note, as most of Colorado has not been inventoried for cultural resources, our files contain incomplete information. Consequently, there is the possibility that as yet unidentified cultural resources exist within the proposed permit area. The requirements under CRS 24-80 part 13 apply and must be followed if human remains are discovered during ground disturbing activities. We thank you for the opportunity to comment.

However, prior to obtaining a permit, an approved water supply plan or decreed plan for augmentation is required. Prior to approving a well permit, the applicant must conduct a field inspection of the site and document the locations of all wells within 600 feet of the permit area. The applicant must then obtain a waiver of objection from all well owners with wells within 600 feet of the permit area or request a hearing before the State Engineer. COMMENTS: The subject application is for a surface mining operation on approximately 544.6 acres located in the SE '/4 of the NE '/4 and the NE '/4 of the SE ',4 and the S ' of the SE 'A of Section 18; the N '/2 of the NE 'A and the E '/z of the NW '-4 and the N ' of the SW 'A of Section 19, the S '/2 of the SW ';4 of Section 19, the SE 'A of Section 19 and the NW '%`z of Section 30, all in Township 4 North, Range 66 West of the 6th P.M. The primary commodities to be mined at the site are sand and gravel intended for construction materials. The mining plan currently includes mining in five major phases ranging in size from 27 to 97 acres that are expected to last approximately 37 years. The mining plan calls for excavation to remove approximately 1,000,000 tons of aggregate per year. Mining will be accomplished by dry -mining method. A continuous soil/bentonite slurry wall will be constructed around the proposed Cell 1 through Cell 4. In addition a unlined Siltation Pond and two Fresh Water Ponds will be located on the mined area. The mined area in the proposed Siltation Pond and Fresh Water Ponds may be backfilled back to native grade and used as farmland or may be converted to a water storage facility if economically feasible. The site is proposed to be reclaimed as water resources for storage of decreed water rights or other water as allowed by this office as well as backfillin g Prior to the use/exposure of any groundwater the applicant must first obtain a well permit and a substitute water supply plan or decreed plan for augmentation. The site must continue to be operated under a substitute water supply plan until such time as the proposed storage reservoirs or backfilling 1313 Sherman Street, Room 821, Denver, Co 80203 P 303.866.3581 www.colorado.gov/water Jared S.

Angelique Curtis - DNR <angelique.curtis@state.co.us>. Boyd Wright - DNR <boyd.wright@state.co.us>, Mike Sherman - DNR <mike.sherman@state.co.us> Good afternoon Rob. CPW appreciates this opportunity to provide DRMS with our following recommendations for the proposed Monarch DENM Mine development, which is located along the South Platte River between the Towns of Gilcrest & Milliken. The mission of Colorado Parks and Wildlife (CPW) is to perpetuate the wildlife resources of the state, to provide a quality state parks system, and to provide enjoyable and sustainable outdoor recreation opportunities that educate and inspire current and future generations to serve as active stewards of Colorado's natural resources. CPW has a statutory responsibility to manage all wildlife species in Colorado: as such we encourage protection for Colorado's wildlife species and habitats through responsible development and land use planning. Our goal in responding to land use proposals is to provide complete. consistent. and timely information to all entities who request comments on matters within our statutory authority. One way we accomplish our mission is by responding to land use requests. as is the case for this proposed gravel mine. The protection of High Priority Habitats (HPHs) is of extreme importance to CPW. CPW recommends that all proposed projects be assessed to prevent the loss of habitat or fragmentation of habitat as well as to avoid, minimize, or mitigate impacts to wildlife species sensitive to development, which can include species of concern, big game winter concentration areas. raptor nests, and breeding and nesting habitats for ground -nesting birds. Therefore. CPW recommends the following wildlife protection measures - based on the proposed work boundary that intercepts or is near the following HPHs: • Bald Eagle Active Nest Site (1/2 & 1/4 -mile nesting buffer) a An active Bald Eagle nest site is a specific location in which a pair of Bald Eagles has attempted to nest within the last five years. Any nest location that can be directly tied to courtship, breeding. or brooding behavior is considered active. CPW has two buffer recommendations to protect these sites: a) a year-round restricted surface occupancy (RSO) 0.25 -mile buffer of any active Bald Eagle nest site. and b) a seasonal (December 1 to July 31) no new human encroachment or permitted/authorized human activities 0.5 -mile buffer of any active bald eagle nest site. Note: The Bald Eagle is designated as an avian Priority Tier 2 Species of Greatest Conservation Need within CPW's 2015 Colorado State Wildlife Action Plan. This designation denotes that these species are in need of conservation attention in Colorado and are provided a relative degree of conservation management priority. ■ CPW read in the Permit Application that the mapped Bald Eagle nest just northwest of the project boundary may have shifted its specific location, but is still present and the 1/4 -mile and 1/2 -mile buffers extend into the project boundary. Therefore. CPW recommends that initial site construction occur outside the nesting season and does not occur within the 1/4 -mile buffer. • Bald Eagle Roost Site o Bald Eagle roost sites are defined as groups of (or individual) trees that provide diurnal and/or nocturnal perches for wintering bald eagles. These trees are usually the tallest available in the wintering area and are primarily located in riparian habitats. CPW has one recommendation to protect these sites: no permitted or authorized human activities within 0.5 -mile of any active Bald Eagle winter night roost if there is a direct line of sight (or 0.25 -mile if there is no direct line of sight) during the winter roost season (November 15 to March 15) • As mentioned in the permit application, there are roosts located just upstream and downstream of this project boundary. and CPW recommends surveys for the riparian area closest to the initial ground disturbance areas if initial construction is slated to occur from November 15 to March 15. If winter roosting Bald Eagles are present, please observe the above recommendations. • Mule Deer Severe Winter Range O Mule Deer Severe Winter Ranges are defined as that part of the overall winter range where 90% of the individuals are located when the annual snowpack is at its maximum and/or temperatures are at a minimum in the two worst winters out of ten. ■ Therefore, CPW recommends no initial ground disturbances in these polygons from December 1 to April 30. o Furthermore, CPW recommends using wildlife -friendly fencing throughout the development. in particular. along the western project boundary that borders the South Platte River. Wildlife -friendly fencing may include four -strand smooth wire as further discussed in CPW's "Fencing with Wildlife in Mind" brochure. • Aquatic Native Species O There are sensitive aquatic native species (fish and amphibians) located within the South Platte River. • Therefore, CPW recommends No Surface Occupancy and No Ground Disturbances (year-round) within 500 feet of the Ordinary High Water Mark of the South Platte River. as well as appropriate stormwater BM Ps. https.//mail.google.com/mail/u/0/?ik=962497745c&view=pt&search=all&permthid=thread-P/03A1731848647536902449&simpl=msg-f%3A1731848647. 4/7 5/5/22, 4:53 PM State.co.us Executive Branch Mail - Re: Notice of Application Consideration for Permit: M2022009 Should you or anyone else have any questions about our wildlife recommendations. please contact me.

OMAHA DISTRICT DENVER REGULATORY OFFICE, 9307 SOUTH WADSWORTH BOULEVARD LITTLETON, COLORADO 80128-6901 SUBJECT: Section 404 of the Clean Water Act Initial Comments To whom it concerns: In accordance with Section 404 of the Clean Water Act, the U.S. Army Corps of Engineers reviews and authorizes any work associated with the discharge of dredged or fill material, and any excavation associated with a dredge or fill project, either temporary or permanent, in waters of the United States. Waters of the United States may include ephemeral, intermittent and perennial streams, wetlands, lakes, ponds, drainage ditches and irrigation ditches. Please note that the discharge of dredged or fill material into upland areas or aquatic resources which are not waters of the United States does not require authorization from this office. Jurisdictional Determinations identify the locations and amounts of aquatic resources within a specified area to determine if they are or are not waters of the United States. Prior to submitting a request fora Jurisdictional Determination. we recommend a wetland delineation be conducted in the field by a qualified environmental consultant. A wetland delineation identifies the boundaries of aquatic resources located within your project area and must be conducted using the methods outlined in the Corps of Engineers Wetlands Delineation Manual and applicable regional supplements. Nationwide Permits authorize common types of dredge and fill activities in waters of the United States that will result in a minimal adverse effect to the environment. Some fill activities require a pre -construction notification (PCN) to the Corps prior to any work and possibly coordination with other local or state agencies. Descriptions of the current nationwide permits and their general conditions can be found at: https://www. nwo. usace. arm y .mil/Missions/Reg ulatory-Program /Colorado/ Regional General Permits authorize specific types of dredge and fill activities in waters of the United States that will result in a minimal adverse effect to the environment. These fill activities require a pre -construction notification to the Corps prior to starting work, and possibly coordination with other local or state agencies. Please note several of the RGP's are applicant and location specific. Descriptions of the current regional general permit activities and their general conditions can be found at: https://www.nwo.usace.army .m il/Missions/Req ulatory-Program/Colorado/Regional- General-Perm its/ Standard Individual Permits authorize dredge and fill activities that do not qualify for Nationwide or Regional General Permits. We recommend contacting the Denver Regulatory Office to arrange for a pre -application consultation prior to applying for a 2 Standard Individual Permit. Standard Individual Permits include public interest review procedures, including public notice, notification of adjacent property owners and review of public and agency comments. Standard Individual Permits require an evaluation of effects for a range of alternatives. The Corps will evaluate practicable (cost. logistics. and technology) alternatives that meet the overall project purpose for environmental effects. Alternatives can include off -site alternatives and alternative designs. When evaluating Standard Individual Permit applications, the Corps can only issue a permit for the least environmentally damaging practicable alternative (LEDPA). In some cases, the LEDPA may not be the applicant's preferred alternative. The Standard Individual Permit application form and instructions can be found at: https://www.usace.army.mil/Missions/Civil-Works/Regulatory-Program-and- Perm its/Obtain-a-Perm it/ A federal action occurs when a discharge of dredged or fill material into waters of the United State requires a Clean Water Act Section 404 permit. For the Corps to make a permit decision, the applicant must provide enough information to demonstrate compliance with Section 106 of the National Historic Preservation Act (NHPA) and Section 7 of the Endangered Species Act (ESA). Dredge and fill activities in waters of the United States must be designed and constructed to avoid and minimize adverse effects. both temporary and permanent. to the maximum extent practicable at the project site. Mitigation; including avoiding; minimizing, rectifying. reducing, or compensating for resource losses, will be required to the extent necessary to ensure that the adverse effects to the aquatic site are minimal. Any loss of function at an aquatic site may require mitigation. Mitigation requirements will be determined during the Clean Water Act Section 404 review process. If the activity you described would impact waters of the United States, the Denver Regulatory Office should be notified. Please include a map identifying dimensions of work in each aquatic site, the county, Township, Range and Section and the latitude and longitude of the activity in decimal degrees, along with a description of your request, to the Denver Regulatory Office mailbox located at DenverRequlatoryMailbox©usace.army.mil or contact the Denver Regulatory Office at 303-979-4120.

backfilling these ponds are substantial, suggesting that there maybe hauling costs in the total amounts in Section B of the table Please clarify and elaborate on the location of stockpiles to be used for backfilling This statement was meant to point out that large quantities of overburden will not be utilized in the 3 1 reclamation slopes since they will be mined at a 3 1 which is why there is no line item for this in each of the slurry wall hned cells The overburden for the reclamation of the Fresh Water Ponds and Siltation Ponds will come from the stockpile north of the plant Item #L3 Explain the differences between Exhibit L and the Mining Plan Map, C-5 In particular, the volumes in Section B of the Reclamation Costs (reclamation of the Freshwater Pond and the Silt Pond) require explanation when compared to the volumes listed on C-5 For example, on the map the volumes for the Siltation Pond are 826,300 CY for AG and 130,600 CY for OB), and in the cost table the value is 655,000 CY (pnor to multiplying by 50%) The Freshwater Pond is approximately 12 acres and will have 1' of topsoil placed in the pit which is already accounted for in line item B 4 The topsoil placed is approximately 20,000 cy The total volume of material extracted from the pit is 422,000 cy minus 20,000 cy equals 402,000 cy I have changed the calculation for the siltation pond to the following reasoning MMMA only needs 10 acres of siltation pond open at a time The whole pond is approximately 25 acres The total material removed is 956,900cy and topsoil added to the pit is approximately 41,000cy The whole pit will require 915,900 cy of overburden to fill the whole 25 acre pit 915,900 cy/ 25 acres = 36,636 cy/acre 36,636 cy/acre x 10 acres e 366,000 cy of fill needed per 10 acres Page 3 Mr. Rob Zuber June 3. 2022 Item #L4 Explain the reason for multiplying by 50% for the volume of the Siltation Pond. Will this pond be large enough to function properly? The 50% has been changed to 10 acres open at one time per the reasoning above. Item #L5 Explain the difference between the unit cost in the text of Section F. for slurry wall costs (S6.92 per SF) and the value in the table ($5.12 per SF). Also, for the slurry wall costs, please include a bid from a contractor to support your estimate. $6.92 was left over from a different project that had a deeper site. $5.12 per SF for the slurry wall curtain was the average of bids we received for a different project with similar depth which has been included with this letter. Item #L 6 Add costs for the construction of the underdrain at Cell 1. Please include a bid from a contractor or other supporting documentation. Costs have been added for the construction of the Cell 1 underdrain and a bid from Fischer Construction including the cost of providing and installing the 6" PVC.
