Currently, pursuant to DRMS Permit No. M-2023-022, the existing site is permitted under a 110c limited impact reclamation permit, consisting of approximately 9.99 permitted acres located in Section 27, T3S, R63W, 6th P.M. in Weld County, Colorado. Pursuant to this application, the expanded site ("Extraction Site") will encompass approximately 335 acres also in Section 27, and include part of Section 34, T3S R63W, 6th P.M. The existing site was basically an exploration permit which was too large to fit under the Notice of Exploration guidelines, so it was permitted as a 110c Frac Sand extraction test area. The site proved to be viable therefore, this application will expand the site to a 112c application with the new permit area overlaying the 110c boundary and expanding out further east, north and south of the existing area. The proposed 112c will encompass approximately 335 acres as shown on the various maps accompanying this application. The site is located in an area of Eastern Colorado consisting of aeolian sandhills located generally between Weld County Road 49 on the West, Interstate 76 on the south, U. S. Highway 34 on the North and more or less, Empire Reservoir along the East. It is similar to other sand hill areas scattered across Eastern Colorado from the Wyoming border on the north to the New Mexico/Oklahoma border on the south, in that it is aeolian deposited sands presently covered with typical Eastern Colorado rangeland vegetation including numerous native grasses and small shrubs such as sagebrush. The sand under these dunes is the target of this mining operation. This sand has a consistency that makes it conducive to its use as Frac Sand in Oil and Gas operations primarily in Weld County. The proposed mining operation will involve stripping and reserving the available topsoil, removing the sand deposit down to an elevation that will leave two (2) feet above the historic groundwater elevation at final reclamation, re -grading the mined area, replacing the topsoil and reseeding with native grasses. The post -mining topography will be relatively level compared to the existing topography which is rolling sandhills. The slopes abutting the adjacent undisturbed lands will be reclaimed to 4H:1V leading down to the relatively level pit floor. Mining will be done using some combination of the following equipment to include front-end loaders, bull -dozers, scrapers, road graders and trucks, including articulating mine site trucks. The site will be divided into 16 units with a main haul road eventually bisecting the site from north to south. This road will be constructed as necessary as each new sequence is mined. The units will be divided more or less equally on both sides of this road with the North Section consisting of units A -E and the South Section consisting of units G -P. As can be seen from the mining plan sequence map (See Exhibit D(2), mining will begin in Unit A followed by set-up of the processing facility in the initial mined area which is centrally located relative to the rest of the units. The plan for this site is to use contemporaneous mining methods so that once the site is opened up, topsoil CoProp LLC — Rodeo Dunes Mine Page 1 of 5 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form will be live handled so as to minimize the necessity for using long-term stockpiles. The method will include four phases of mining and reclamation including, freshly stripped areas ready for mining, active mining areas, mined out areas that have been regraded and are ready to receive topsoil, topsoiled areas where full reclamation has occurred but are awaiting final vegetative establishment. In this way, topsoil that is salvaged in advance of mining will be live -handled and placed directly in mined out areas that have been regraded. The replaced topsoil will then be re- graded and conditioned/prepared to be seeded, either with a cover crop or with the final seed mix, depending on the time of year when the soil is replaced. This method and plan also allow for phased bonding which encourages timely reclamation. The initial disturbance has already occurred in the existing 110c. This liability will be transferred over to the 112 once it is approved and the operator will seek release of the financial warranty for the existing 110c area. The initial disturbance with the newly permitted 112 will involve construction of the main haul road into Unit A. Topsoil will be stripped and stockpiled in the main topsoil stockpile along the south side of Unit A for use during final reclamation. The road will be constructed as necessary as each unit is mined utilizing a small borrow ditch on both sides and be approximately 20 feet in width. This road will likely be surfaced with imported road base. The units are divided more or less equally on both sides of the road beginning in the North Section. Mining will then begin in Unit A with topsoil stripping. This soil will also be stockpiled along the Southern boundary of Unit A beginning in the southwest corner and going east. This stockpile will then be seeded and remain in place until final reclamation of the site is used to reclaim Units P and A at the end of mining the entire site. Once topsoil is stripped from Unit A, mining will commence along the Eastern side moving from east to west. The minedmaterial will be stockpiled towards the west end of Unit A and the new processing facility will be constructed on the Eastern half of Unit A. A separate diagram is being provided showing the details of the processing area. Once the processing area is up and running the previously mined stockpile will be processed and the rest of Unit A will be mined and processed with the process reject stockpiled in an area where it can be easily incorporated during final grading after mining. Upon completion of mining and regrading of Unit A, topsoil salvage will ensue along the south end of Unit B, with this salvaged topsoil also being placed in the topsoil stockpile along the southern end of Unit A. As approximately '/2 of Unit A will be occupied by processing and the other half by ancillary facilities, topsoil from Unit B will be stockpiled in in the existing Unit A topsoil stockpile area to be used in final reclamation of Units A and P at the conclusion of mining. Mining will then commence in Unit B heading north towards Unit C. When a large enough area has been mined and regraded in Unit B, topsoil stripping will commence in the south side of Unit C with placement in the regraded portion of the south side of Unit B. At this point all remaining topsoil that is stripped in advance of mining will be live -handled and replaced immediately on an area that has been mined and regraded to its final elevation. At this point, the disturbance will be at its maximum size for full bonding with all of Unit A disturbed and Un- reclaimed and all of Units B and C in some phase of disturbance/reclamation including reseeded, regraded and topsoil replaced, mined and regraded, active mining, and topsoil stripping in advance of mining. The mining will then progress north through Units C and D and then turn back south through Unit E and back to unit A to complete the North Section. CoProp LLC — Rodeo Dunes Mine Page 2 of 5 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Fonn At this point mining will commence in the South Section beginning in Unit F. Topsoil from Unit F will be live -handled to Unit E and mining will progress in a clockwise direction to Unit G and then south to Unit K before turning North again to head back to Unit P. Once mining is completed in Unit P, topsoil that was stockpiled during mining of Units A and B will be used to reclaim Unit P and then ultimately Unit A. (b) Earthmoving. In addition to the earthmoving described in section (a) above, earthmoving will be limited to replacing topsoil, along with grading and leveling the same. (c) All water diversions and impoundments. No water will be diverted or impounded as a result of the operation. During mining, given the porous nature of the substratum, any storm water that falls directly on the site is expected to infiltrate back into the ground within 72 hours of a storm event. (d) The size of area(s) to be worked at any one time. Applicant intends to actively mine approximately 10 acres at a time. However, there will also be 10 acres of active topsoil stripping, 10 acres being regraded and 10 acres being re-topsoiled and re -seeded. In the active mining area as mining advances, reclamation will be occurring contemporaneously so as to minimize the amount of maximum disturbance to 50 acres plus an ever-expanding area that has been fully reclaimed. This is in addition to 20 acres in Unit A that will not be reclaimed until the entire site has been mined out. Therefore, for bonding purposes, 70 acres will be the maximum area disturbed at any given time. This breaks down to 20 acres in Unit A, 40 acres in the active mining area and 10 acres that have been seeded and are in the initial state of emergence and establishment. The haul road will be constructed as mining advances and reclaimed as reclamation occurs, therefore, costs to reclaim this road are included in reclamation of each unit. (e) An approximate timetable to describe the mining operation. (i) An estimate of the periods of time which will be required for the various stages or phases of the operation. It is expected that each Unit of mining will take 3 months to 1 year to complete, therefore, based on expected market conditions and estimated reserves, it will take 5-12 years to complete mining at this site. (ii) A description of the size and location of each area to be worked during each phase. As described above, the applicant intends to mine approximately 10 acres at a time in addition to 10 acres of topsoil stripping, 10 acres of regrading, 10 acres of replaced and reseeded topsoil and 10 acres that have received final seeding and awaiting vegetative establishment See attached Plan Sheets (Exhibits D -1-D-8). CoProp LLC — Rodeo Dunes Mine Page 3 of 5 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form (iii) An outline of the sequence in which each stage or phase of the operation will be carried out. The active mining site will consist of 10 acres of topsoil being stripped in advance of 10 acres being mined, in advance of 10 acres being regraded, in advance of 10 acres being topsoiled in advance of 10 acres being seeded. Using this mining sequence, applicant will have 50 acres in various stages of disturbance/reclamation plus 20 acres in Unit A housing the processing and ancillary support areas. See attached Plan Sheets (Exhibits D-1 — D-8) (1) A map (in Exhibit C - Pre -Mining and Mining Plan Maps(s) of Affected Lands, Rule 6.4.3) may be used along with a narrative to present the following information: (i) nature, depth and thickness of the deposit to be mined and the thickness and type of overburden to be removed (may be marked "CONFIDENTIAL," pursuant to Rule 1.3(3)). The general thickness of the material to be mined is approximately 15 feet on average. Approximately 6 to 12 inches of topsoil will be removed first. There is little to no overburden between the topsoil and the material to be mined. Mining will extend approximately 10 feet below the elevation of the access road to the west of the site and extend across the mined area at this elevation. (ii) nature of the stratum immediately beneath the material to be mined in sedimentary deposits. Based upon mining in the 110c, the stratum underneath the material to be mined consists of water saturated sand. Mining will not expose groundwater and there will be a minimum of 2 feet of cover above the historic groundwater elevation at the conclusion of reclamation so as to prevent the exposure of groundwater to the atmosphere. (g) Identify the primary and secondary commodities to be mined/extracted and describe the intended use. The primary commodity to be mined will be Frac Sand. There are no secondary commodities; however, there will be waste product or reject material that will be placed back and regraded into the mined areas. (h) Name and describe the intended use of all expected incidental products to be mined/extracted by the proposed operation. Applicant does not expect any incidental products to be mined or extracted by the proposed operation at this time. CoProp LLC — Rodeo Dunes Mine Page 4 of 5 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form (i) Specify if explosives will be used in conjunction with the mining (or reclamation). In consultation with the Office, the Applicant must demonstrate pursuant to Rule 6.5(4), Geotechnical Stability Exhibit, that off -site areas will not be adversely affected by blasting. No explosives will be used in conjunction with mining or reclamation. (j) 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 upgraded to support the mining operation. Describe any associated drainage and runoff conveyance structures to include sufficient information to evaluate structure sizing. Mining traffic will enter and leave the site via the pre-existing road which is approximately 20 feet wide. A road will be constructed beginning on the west side of Unit A where the pre- existing road currently is located adjacent to the permit area. This road will be constructed into Unit A from that point and remain in place until final reclamation occurs. No new roads are needed to access the proposed operation at this time and no improvements are necessary for the existing access route. The road will be maintained as necessary to allow continued access into the mining site. Additional internal haul roads will be constructed as mining commences to the north between Units A and B. This road will bifurcate the Units and be extended to the north to accommodate haulage from the North Section Units back to the Processing Site in Unit A. The road will be constructed on an as needed basis up to the bottom of Unit D and reclaimed as mining moves back south to Unit A. Then as mining progresses into the South Section, the haul road will bifurcate the South Units and be constructed as needed down to Unit J and then reclaimed as mining and reclamation move back north to Unit A. By doing it this way, reclamation of the road is incorporated into reclamation of the mining units.

Operators/Applicants are encouraged to allow flexibility in their plans by committing themselves to ranges of numbers (e.g., 6"-12" of topsoil) rather than specific figures. Reclamation of the permit area will return the site to a post -mining land use of rangeland, which is consistent with the surrounding area. Grading will be done, as necessary, to create a grade that conforms to the post -mining use of rangeland. Grading will also be done in a manner to control erosion and siltation of the affected lands, and to protect areas outside the affected land from slides and other damage. The final grade will slope very gently (0-1%) to the northeast with the perimeter slopes leading down to the pit floor at 4H:1 V. Topsoil from the site will be replaced from where it was removed and will be reseeded with a mixture of native grasses to conform with the condition of the site prior to the operation. Seeding will occur on an ongoing basis during the first favorable season following topsoil replacement. (2) The Reclamation Plan shall include provisions for, or satisfactory explanation of, all general requirements for the type of reclamation proposed to be implemented by the Operator/Applicant. Reclamation shall be required on all the affected land. The Reclamation Plans shall include: (a) A description of the type(s) of reclamation the Operator/Applicant 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 entire permitted site will be reclaimed to rangeland which is compatible with the pre - mining land use and the adjacent surrounding property. The post -mining topography will be relatively level compared to the rolling sandhills that are currently present across the site, as these are the target of this mining operation. Six to twelve (6-12) inches of topsoil will be removed and replaced across the entire area. Most of the stripped topsoil will be live handled, meaning once it is removed, it will be direct hauled to a re -graded site behind the active mining area and placed in its final location prior to soil prep and seeding. Some of the initial topsoil that is stripped will be stockpiled and seeded for use later in the reclamation process. These stockpile locations are shown on the mining plan maps. After topsoil is stripped, the underlying sand will be extracted to a minimum depth of 18 inches above the historic groundwater level utilizing real time data from the seven installed CoProp LLC — Rodeo Dunes Mine Page 1 of 6 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form piezometers to maintain this level. The extraction will be conducted using front end loaders and trucks for transport to the processing area where the material will be screened to create a markable product. The reject material from the screening process will be transported back to the same unit where it was extracted and stockpiled until the unit is regraded at which time this material will be mixed into the surface of the regraded area. The site will graded to be relatively level compared to the pre -mining topography with 4H:1 V sideslopes around the perimeter. Topsoil will then be replaced at a depth of 6"-12" so that there will be a minimun of two feet of cover above the historic groundwater elevation which will prevent exposure of any groundwater to the atomosphere. After the mined area is regraded and topsoil had been reapplied, the soil will be graded out and conditioned using standard farm equipment. These areas will then be seeded with either the final approved rangeland seed mix or a cover crop depending on the time of year. This is detailed further below. (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. In those instances where the post -mining land use is for industrial, residential, or commercial purposes and such use is not reasonably assured, a plan for revegetation shall be submitted. Appropriate evidence supporting such reasonable assurance shall be submitted; The currently permitted area as well as the proposed affected land are rangeland with native grasses. Applicant does not intend to change the current land use. Upon completion of mining, the applicant intends to reclaim the mined area to rangeland with native grasses. This land use is consistent with land uses in the vicinity. (c) A description of how the Reclamation Plan will be implemented to meet each applicable requirement of Rule 3.1; This Exhibit and other Exhibits in this Application address all applicable requirements of Rule 3.1. Included with this exhibit are four Plan Sheets outlining the entire mining and reclamation sequence that will be used through the end of the project. Each of these sheets identifies all five phases of pre -mining, mining, grading, reclamation and post reclamation. This concept will then be applied in alpha sequential order A -P throughout the life of mine. The mine plan is divided into sixteen (16 Units (A -P) in two (2) Sections (North and South) by an east -west line located at the bottom of Unit A. A haul road running North to South will be constructed as needed and splits the proposed permit area almost exactly in half and is tangential to each of the units. The site will have a North Section comprised of five (5) Units (A -E) and the South Section will have 11 Units (G -P). The concept is for mining and reclamation to occur contemporaneously so as to minimize the amount of full disturbance and conduct reclamation in a timely manner. The order of mining and reclamation is structured to move in a counterclockwise direction in the North Section and a clockwise direction in the South Section. By doing it this way the disturbance will end just below Unit A where the first topsoil stockpile will be located and it will be used to reclaim Unit P and Unit A at the conclusion of mining. CoProp LLC — Rodeo Dunes Mine Page 2 of 6 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form (d) Where applicable, plans for topsoil segregation, preservation, and replacement; for stabilization, compaction, and grading of spoil; and for revegetation. The revegetation plan shall contain a list of the preferred species of grass, legumes, forbs, shrubs or trees to be planted, the method and rates of seeding and planting, the estimated availability of viable seeds in sufficient quantities of the species proposed to be used, and the proposed time of seeding and planting; Approximately 6-12 inches of topsoil will be available for salvage across the entire mining area. Topsoil will be salvaged prior to any disturbance occurring. Topsoil stockpiles will be located in places and configurations so as to minimize erosion and located in areas where disturbance by ongoing mining operations will be minimized. Any stockpiled topsoil shall be disturbed as little as possible until replacement on the regraded area. Furthermore, topsoil remaining in place for more than 180 days will be seeded with an approved seed mix. Approximately 64,000 to128,000 cubic yards of topsoil will be stored in the main topsoil stockpile located along a line running east -west between Units A and P. (e) A plan or schedule indicating how and when reclamation will be implemented. Such plan or schedule shall not be tied to any specific date but shall be tied to implementation or completion of different stages of the mining operation as described in Rule 6.4.4(e). The plan or schedule shall include: (i) An estimate of the periods of time which will be required for the various stages or phases of reclamation; It is expected that each Unit of mining will take 3-12 months to mine out therefore, based on expected market conditions, it will take 4-12 years to complete mining of the entire site. (ii) A description of the size and location of each area to be reclaimed during each phase; and There will be 20 acres in Unit A where the processing facility will be located that will not be reclaimed until all mining and processing is completed. Approximately 30 acres will be maximally disturbed at any given time including, the topsoil stripping area in advance of mining, the active extraction area and the area being regraded following extraction. In addition, there will be two additional areas equal to 20 additional acres that will not be fully reclaimed but in various stages of final reclamation. These include the regraded area where topsoil has been re -applied at 6-12 inches and is being prepared for interim or final seeding and a final area where reclamation has occurred through seeding, but grasses have yet to establish. The reclaimed phase will continue to grow through time as the overall plan advances. Applicant's mining and reclamation operations are depicted in the phased Plan Sheets Showing Units A -D. This concept will continue in alpha sequential order until mining is completed. (iii) An outline of the sequence in which each stage or phase of reclamation will be carried out. (The schedule need not be separate and distinct from the Reclamation Plan but may be incorporated therein.) CoProp LLC — Rodeo Dunes Mine Page 3 of 6 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form The applicant intends to maximally disturb only thirty (30) acres at any given time while simultaneously reclaiming the regraded area following this disturbance. The maximum disturbance area will include the ten -acre area where topsoil has been stripped in advance of the extraction and the 10 -acre active extraction area. Also included in this maximally disturbed area will be the 10 -acre regraded pit floor which will be ready to receive topsoil that will be stripped in advance of the mining. Once topsoil is replaced it will be graded and conditioned for seeding by the addition of manure followed by discing and firming up the seed bed. Seeding will then occur as described under (f)(ii) below. Other areas that will need to be bonded include the processing area, product stockpile and loadout area, and any necessary access/parking areas, etc. located in Unit A. (f) A description of each of the following: (i) Final grading - specify maximum anticipated slope gradient or expected ranges thereof; No highwalls are expected at the site and all slopes leading into the excavated site will be regraded to 4H:1 V or flatter. The reclaimed pit floors will be re -graded to be nearly level (0-1%) d raining slightly to the northeast. Upon placement of topsoil, the area will be graded level, and 20 tons/acre of manure will be applied. This will be incorporated using a disc followed by culti-packing to firm up the seed bed. ii) Seeding - specify types, mixtures, quantities, and expected time(s) of seeding and planting; The following seed mix is representative of native vegetative cover on the site and will be used for all seeding applications including seeding topsoil stockpiles remaining in place for more than 180 days. This is the seeding rate for drill seeding and the rate will be doubled if broadcast seeding is utilized. Seeding will occur during the first favorable season after topsoil has been replaced, graded and conditioned. The ideal seeding season for this mix would occur during its dormant phase which would be after October 15 and prior to April 15. If soil has been placed and prepared outside of these favorable seeding windows, a cover crop of oats (in spring during the month of May) or sorghum (in summer June - August) will be used to provide erosion and weed control as well as providing a standing cover mulch prior to seeding with the permanent grass seed mix during the next dormant seeding window. In early spring seeding (March -April) oats may also be inter -seeded as a companion crop at a rate of 15-20 pounds per acre. If soil is prepared after the spring/summer growing season, thereby requiring dormant seeding (from October -March), straw mulch will be applied at 2 tons/acre and crimped in following seeding. CoProp LLC — Rodeo Dunes Mine Page 4 of 6 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form As the soils in this area are quite sandy, it will be necessary to have either a standing cover crop to seed into or utilize straw mulch at the time of seeding to prevent erosion. If seeding occurs from Mid -March to early May, a companion crop of oats would also be sufficient.

CoProp LLC — Rodeo Dunes Mine Page 5 of 6 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form All topsoil removed will be replaced as plant growth medium. Applicant expects 6 to 12 inches of topsoil will be removed, as practicable. All topsoil will be evenly distributed over the areas from which it was removed in thicknesses equal to the original topsoil depths found at the site. Prior to removing topsoil, applicant shall determine available soils sufficiently to establish quantity and quality in order to ensure consistency during reclamation. CoProp LLC — Rodeo Dunes Mine Page 6 of 6 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form EXHIBIT G Rule 6.4.7 Water Information (1) If the operation is not expected to directly affect surface or groundwater systems, a statement and sufficient demonstration of that expectation shall be submitted. The operation is not expected to directly affect surface or groundwater systems. Based on information available from the Colorado Division of Water Resources CDSS, there is no surface water on or within 200 feet of the affected land. In addition, based on well construction reports for the nearest permitted water wells, and data gathered from a series of piezometers installed around the permit area, the water table is located below the level at which the deposit will be excavated. In fact, this information will be used to manage the excavation depth to maintain at least a one and half foot buffer above the highest known groundwater elevation within the permit area during mining operation (two feet upon final reclamation). (2) If the operation is expected to directly affect surface or groundwater systems, the Operator/Applicant shall: (a) Locate on the map (in Exhibit C) tributary water courses, wells, springs, stock water ponds, reservoirs, and ditches on the affected land and on adjacent lands where such structures may be affected by the proposed mining operations. See Exhibit C(b)(1) - Creeks and water in area. None of these features are located on or near the affected lands. Additionally, as the static water level is below the level of mining, no impacts are expected on the surrounding area. (b) Identify all known aquifers; and The Lost Creek Aquifer is located below this mining operation. (c) Submit a brief statement or plan showing how water from de -watering operations or from runoff from disturbed areas, piled material and operating surfaces will be managed to protect against pollution of either surface or groundwater (and, where applicable, control pollution in a manner that is consistent with water quality discharge permits), both during and after the operation. This operation is in Weld County, in Eastern Colorado sand hills and the target of the operation is the sand located within these hills. There will be minimal to no runoff due to the porous nature of the sand. All precipitation that falls onsite will infiltrate into the ground within 72 hours of the event. No explosives will be used during extraction. Only heavy equipment such as front-end loaders, bulldozers, trucks, road graders, and scrapers will be used in mining. In addition, some common farm equipment will be utilized during reclamation. The near surface shallow aquifer has been identified and mapped using a CoProp LLC — Rodeo Dunes Mine Page 1 of 2 Construction Materials Regular Operation (112(c)) Reclamation Permit Application Form series of piezometers to identify the groundwater elevation and the thickness of the deposit that can be mined, but mining will stay above the anticipated groundwater elevation by a minimum of one and half feet during mining operations. Processing will involve physical separation equipment including conveyors and screens followed by some drying on an as needed basis. No other chemicals or reagents will be used in the screening process. The screened reject materials will be returned to areas where they were excavated and be regraded across these sites prior to re -application of topsoil. Therefore, neither mining nor processing will expose the groundwater or introduce elements that could be harmful to the groundwater or surface water above the mining area or in the surrounding area. (3) The Operator/Applicant shall provide an estimate of the project water requirements including flow rates and annual volumes for the development, mining and reclamation phases of the project. Dust control will require minimal water to be sourced and brought in from off site on an as needed basis. (4) The Operator/Applicant shall indicate the projected amount from each of the sources of water to supply the project water requirements for the mining operation and reclamation. No project water is required. This is a dry pit operation, and no washing is to take place. This is a dry pit. No water is required, except for the water used for dust control by truck/tanker. (5) The Operator/Applicant shall affirmatively state that the Operator/Applicant has acquired (or has applied for) a National Pollutant Discharge Elimination System (NPDES) permit from the Water Quality Control Division at the Colorado Department of Health and Environment, if necessary. As no water will be used in processing and no water will be discharged from this site, it will not be necessary to obtain a stormwater permit. All precipitation that falls within the boundary of the permit area will be retained onsite and allowed to infiltrate into the ground within 72 hours of any precipitation event.

Job Number 24-3520 — Revision 1 John Dietzler Dietzler Companies 1625 Broadway, Suite 2650 Denver, Colorado 80202 Dear Mr. Dietzler: This correspondence provides a summary of a geotechnical data collection program performed by GROUND Engineering Consultants, Inc. (GROUND) for Dietzler Companies (Client) to provide geotechnical data at the proposed Cervi Sand Mine located approximately 8 miles south of the intersection of US -34 and County Road 69 in Weld County, Colorado. Our study was conducted in general accordance the GROUND's Proposal Number 2401-0153 dated January 26, 2024. A field exploration program was conducted to obtain information on the subsurface conditions. The results of the field exploration are presented herein. This report has been prepared to summarize the data obtained. This report should be u nderstood and utilized in its entirety; specific sections of the text, drawings, graphs, tables, and other information contained within this report are intended to be understood in the context of the entire report. This includes the Closure section of the report which o utlines important limitations on the information contained herein. This report was prepared for Dietzler Companies based on our understanding of the proposed project at the time of preparation of this report. The data provided herein should n ot be construed to be sufficient for other purposes, including the use by contractors, or any other parties for any reason not specifically related to the design of the project. Furthermore, the information provided in this report was based on the exploration and testing methods described below. Deviations between what was reported herein and the actual surface and/or subsurface conditions may exist, and in some cases those deviations may be significant. This report was revised to incorporate the Client -provided surveyed elevations of the test holes. 41 Inverness Drive East I Englewood, CO 80112 I (303) 289-1989 I www.groundeng.com ENGLEWOOD I COMMERCE CITY I LOVELAND I GRANBY I GYPSUM I COLORADO SPRINGS Cervi Sand Mine - Piezometers Weld County, Colorado Revision 1 Proposed Construction Based on the provided information and marked up site plan (Cervi Soil Survey Map (Mine Area) w Proposed Piezometer Locations.pdf), we understand that the geotechnical data has been requested in support of a proposed sand quarry operation. Temporary groundwater monitoring and observation holes have been requested in this area to measure the depth to groundwater. The project site is shown on Figure 1. If our described understanding/interpretation of the proposed project is incorrect or project elements differ in any way from that expressed above, including changes to the location of the alignment, dimensions, orientations, elevations/grades, etc., and/or structures/site improvements are incorporated into this project, either after the original information was provided to us or after the date of this report, GROUND or another geotechnical engineer must be retained to reevaluate the conclusions and parameters presented herein. Site Conditions At the time of our subsurface exploration, the project site consisted of a largely vacant parcel with local oil and gas development. A gravel -surfaced access road was observed to the north of the site which extended north towards US -34. Barbed wire fences were observed along the margins of site. They also partitioned the site, with fences extending through the central and southern portions of the site. A cattle water trough and an oil and gas tanks and piping were noted to the west of Test Hole 3. Another gravel -surfaced access road extended northeast from the oil and gas tanks towards the access road north of the site. An overhead utility alignment extended north -south near the eastern margin of the site, and appeared to include powerlines. The remainder of the site supported medium to tall grasses and weeds. Job No. 24-3520 Ground Engineering Consultants, Inc. Page 2 of 7 Cervi Sand Mine - Piezometers Weld County, Colorado Revision 1 Segments of green PVC pipe protruding from the ground with white caps were noted at 2 locations in the western portion of the site. The PVC was accompanied by wood posts on 2 sides. The general topography of the site descended towards the east and southeast, with many scattered dunes. Based on our field estimations, the dunes appeared to range from about 5 to 30 feet in height. Dunes were generally taller and more frequent in the northeastern portion of the site, with heights ranging from about 10 to 30 feet. Dunes became less frequent and shorter towards the southern and western portions of the site, with observed heights ranging from about 5 to 15 feet. The long axis of the dunes was generally oriented in the north -south direction. Based on review of historical aerial imagery available on Google Earth, the site appears to have remained relatively unchanged since the earliest available images (1990s). Subsurface Exploration The subsurface exploration for the project was conducted on February 13 through 15, 2024. Seven (7) test holes were drilled with a buggy -mounted drilling rig advancing continuous flight auger to evaluate the subsurface conditions as well as to retrieve soil and bedrock samples. The test holes were drilled at locations selected by the Client in the field, to depths of approximately 20 to 311/2 feet below existing grades. GROUND directed the subsurface exploration and logged the test hole in the field. Samples of the subsurface materials were retrieved with a 1% -inch inner diameter standard penetration test sampler. The sampler was driven into the substrata with blows from a 140 -pound hammer falling 30 inches, in general accordance with the Standard Penetration Test described by ASTM Method D1586. Penetration resistance values, when properly evaluated, indicate the relative density or consistency of soils. Depths at which the samples were obtained and associated penetration resistance values are shown on the test hole logs. Test Hole locations were determined in the field by the Client, and a hand-held GPS device was used to record the location of the test holes. The approximate locations of the test holes are shown in Figure 1. Logs of the exploratory test holes is presented in Figure 2. Explanatory notes and a legend are provided in Figure 3. The elevations of the test holes were hung to surveyed elevations provided by the Client via email dated April 15, 2024. Job No. 24-3520 Ground Engineering Consultants, Inc.

Iron staining and iron concretions were noted locally. Groundwater was encountered in the test holes at depths ranging from 4 to 21 feet below existing grades at the time of drilling. Groundwater levels can be expected to fluctuate, however, in response to annual and longer -term cycles of precipitation, irrigation, surface drainage, nearby rivers and creeks, land use, and the development of transient, perched water conditions. The groundwater observations performed during our exploration must be interpreted carefully as they are short-term and do not constitute a groundwater study. In the event the Client desires additional/repeated groundwater level observations, GROUND should be contacted; additional fees will be necessary in this regard. Additional depth to water measurements were made in Test Holes 1 and 5 approximately 2 days after drilling. Two more sets of depth to groundwater measurements were made in all of the test holes approximately 2 and 6 weeks after drilling. The table presented below summarizes the data collected from these measurements. The depth to groundwater was taken from existing grades.

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.nres.usda.gov/wps/ portal/nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center Ottps.//offices.sc.egov.usda.gov/locator/app?agency=nres) 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.

The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms 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. 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. 9 Custom Soil Resource Report Weld County, Colorado, Southern Part 35—Loup-Boel loamy sands, 0 to 3 percent slopes Map Unit Setting National map unit symbol: 362f Elevation: 4,550 to 4,750 feet Mean annual precipitation: 11 to 15 inches Mean annual air temperature: 46 to 52 degrees F Frost -free period: 130 to 180 days Farmland classification: Not prime farmland Map Unit Composition Loup and similar soils: 55 percent Boel and similar soils: 35 percent Minor components: 10 percent Estimates are based on observations, descriptions, and transects of the mapunit.
