(TR-03), Revised Mine Plan; Preliminary Adequacy RESPONSE
Dear Mr. Zuber,
The Division of Reclamation, Mining and Safety (Division/DRMS), Office of Mined Land
Reclamation (OMLR); reviewed the contents of the Technical Revision (TR-03) of the Revised
Mine Plan for the P122 — Resource Development Project (RDP), File No. M-2015-033. Raptor
Materials received a Preliminary Adequacy Review dated April 22, 2024. Raptor's first
adequacy responses below follow the comments from the adequacy review and are highlighted
in blue font for clarity.
DRMS Comment no.1
In the TR-03 application, it is stated that eight areas are no longer setbacks for oil and gas wells.
Please explain where these are located (preferably with a map). The currently approved Map C-
2 appears to only indicate four of these areas.
There are eight plugged and abandoned oil and gas wells, located in five separate areas,
indicated on the originally submitted Exhibit C-2:
• Parker 11-33
• Parker#1
• Parker 21-33
• Parker 2-0-33
• Parker 4-2-33
• Parker 2-4-33
• Parker 22-33
• Parker 12-33
DRMS Comment no.2
The proposed Map C-2 must indicate all important features of the mining activities on
site. This includes the conveyors and the ponds at the northwest corner of the site.
Map Exhibit C-2 has been updated to include the conveyor and ponds.
DRMS Comment no.3
Please improve the yellow line indicating the permit boundary, including the areas near the
entrance at the north side and around the homestead. If there is a reason that this line crosses
itself, please explain.
Map Exhibits C-1, C-2, L, F, G, and I -J have been republished with the corrected permit
boundary linework.
DRMS Comment no.4
In Exhibit D, it is noted that part of the extraction, including the western wall, has been
reclaimed. This text also needs to include a commitment for the longest length of extraction
wall that will be un- reclaimed, in the worst -case scenario. This information is necessary for
the Division to clearly understand the Mining Plan and to develop a cost estimate for bonding.
With the modified extraction limits and somewhat shallower sand and gravel than originally
expected in Tract B (East Basin), the remaining mining area will be extracted faster than
originally anticipated as reflected in Exhibit D of this Technical Revision. When fully extracted,
there would be an estimated 9,357 remaining linear feet of wall that would need to be
reclaimed in a worst -case scenario. Raptor intends to continue progressive regrading which will
likely mean the exposed highwall that requires regrading will not reach this amount, but this is
the absolute worst case. Exhibits D and L have been modified to include a statement to this
effect.
DBMS Comment no.5
Exhibit L indicates the length of conveyor to be decommissioned, 3,521 linear feet. Please
explain which part of the conveyor this represents, using a map as necessary.
The length of conveyor to be removed has been updated to 3,412 linear feet, as represented on
Map Exhibit L-2. The resulting cost of processing decommissioning has been reduced from
$54,904.36 to $53,314.09, and the resultant total financial warranty has been reduced from
$748,432.91 to $746,455.65, as updated in Exhibit L.

6.4.4 EXHIBIT D — Mining Plan
Note: For additional information on features and areas described, please refer to
Exhibit C-1: Existing Conditions Map and C-2: Extraction Map.
This is a plan of extraction of a valuable mineral resource for the processing,
stockpiling, and sale of essential construction materials to serve the needs of the
areas urban and rural economic matrix and correlated infrastructure. The effects will
return the affected lands to developed water resources.
From the approved Colorado Office of Mined Land Reclamation (OMLR) permit,
Exhibit D - Extraction Plan (Note: Acreages referenced herein have been updated
based upon subsequent OMLR approved Review):
On April 27, 2023, DRMS approved an Acreage Reduction (AR -01) of the permit from
156.78± acres by 0.92 acres to a new acreage within the permit boundary of 155.86±
acres. The 155.86± Acre permit boundary contains two areas of planned extraction
bounded by extraction limits and identified as Tract A - West Basin and Tract B - East
Basin. Each area of planned extraction includes the following:
51.96±
59.09±
111.05±
Acres of Planned Extraction -Tract A- 5-15± years.
Acres of Planned Extraction - Tract B - 10-20± years.
Acres of Planned Extraction -TOTAL
The formerly designated Mineral Reserve Area 1 between Tracts A & B is now
included in the Tract B extraction area. While maintaining the reference to separate
Tracts A (West Basin) and B (East Basin), it is anticipated that this will become one
large open extraction area that will be converted to a single lined reservoir upon
completion of mining. Several areas set aside as setbacks from oil and gas wells now
plugged and abandoned are also now included in the extraction areas.
Of the remaining 44.81± acres of the permit boundary, 20.32± acres comprise
existing and permanent access roads, irrigation laterals, and setbacks or areas of
pre-existing, minor, to no disturbance. The southern 24.49± acres comprise a plant
processing and stockpile area, as well as a mineral reserve.
Extraction will not occur within the remaining Mineral Reserve Area until and unless
identified, detailed, and approval under a separate technical revision to the OMLR
permit. Until that time the remaining Mineral Reserve Area may be used to support
both wet and dry plant operations and stockpiling of processed materials.
A portable scalehouse/office may also be located in the Mineral Reserve Area. The
actual location, extent, and facilities will be detailed and identified by location and
extent in a later technical revision to the original approved permit. No on -site storage
of fuels is planned as portable fuel (trucks) will service all heavy and correlated
operational equipment. An electrical line serving operations is not shown on included

maps as it is established by the operator, temporary, and subject to relocation in
cooperation with United Power Company. All other power and related overhead or
buried lines are outside of the influence of extraction activity or will otherwise be
relocated in cooperation with their owners or other responsible parties where they
conflict within the interior of planned extraction. Buried oil and gas lines are estimated,
and extraction and offset of operations are approximate and will be determined in the field
in cooperation with the Utility Notification Center of Colorado.
It should be noted that a homestead and yard with outbuildings subsequent to the
2023 Acreage Reduction now occupies 2.42± acres and acts to divide the north
central permit boundary. The access road leading to the homestead has an active
easement for operations which will be used as secondary access for light vehicles
and equipment. Immediately south of the residential yard, existing facilities prevent
the area from being used other than as a storage or parking area for vehicles,
equipment (including heavy equipment), supplies, or other operational support
purposes. This location is fully disturbed by prior agricultural and landowner
purposes. This may also include the placement or construction of storage structures
and materials.
The primary access for heavy equipment, service vehicles, haul trucks and related traffic
is located along an established access road that traverses the east line of the permit
boundary. Both access roads intersect Weld County Road 28 that flanks the northern
extent of the permit boundary. A grader and water truck maintain access within the permit
area as necessary throughout operations.
The aggregate deposit varies in composition, depth and extent. Generally, depths are
shallower toward the southeast, trending deeper toward the northwest, and are consistent
with the gradient flow of groundwater which appears to be at stasis near elevation 4795
feet. Tract B (East Basin) falls from 15-45± feet and Tract A (West Basin) from 35-55±
feet from the surface to the underlying unconsolidated bottom. Unconsolidated suitably
derived on -site material may be used for diverse purposes, including commercial
products, or the re -grading of the extracted basin. These same materials may also be
used to line the completed basins (refer to Exhibit G - Water Resources, Part 6 for details
on how completed basins will be lined). The lined basins form the primary end use as a
developed water resource, and will be utilized accordingly.
To facilitate dry extraction of overburden and aggregate, groundwater will be discharged
from the areas of active extraction at one or more of the three designated discharge
locations identified on Exhibit C-2: Extraction Plan Map. Discharge of waters will be
conducted under an approved Colorado Dept. of Health discharge permit, as indicated
under Exhibit M - Other Permits.
The FEMA designated flood plain was severed in 1911 with the construction of the Union
Pacific railroad bed located approximately 1 mile to the west. While found within and

along the terminus of the upper terrace of the historic floodplain of St. Vrain Creek,
operations will not impact the active FEMA designated floodplain.
The general direction of extraction activities over the Tracts is from north to south, as
shown on Exhibit C-2 - Extraction Plan Map. No extraction will occur within
125 feet of a residential structure, or ten feet of any other structure, property
boundary, right-of-way, or easement without written agreement with the owner of said
structure. These setbacks supersede any representation of the extraction limits
shown on Exhibit C-2: Extraction Plan Map.
Extraction activities will be limited to within 25.0± feet of well heads and facilities, and
those same wellheads will be backfilled to create a 100± foot radius around the well
head for future oil and gas activities at that well head. The fill around well heads will
occur concurrently with extraction around the well head and facilities, to the extent
practical. At all times, safety will take precedent and over -ride as necessary any
element of the permit to assure protection of life and property and compliance with
federal safety regulations (MSHA). Changes resulting from a safety consideration
that require a modification of the approved permit will be made after the fact
respective of amendment or technical revision provisions of the Office of Mined Land
Reclamation (OMLR).
Initially, heavy equipment (typically, scrapers, dozers, or excavators operating alone
or in combination) will extract soil, placing it along the basin perimeter in the
construction of up to a five (5.0±) foot high visual berm. The berm may vary in height
and width. Outslopes of the berm will be 3H:1 V or flatter to aid establishment of
grasses and utilizing the approved seed mixture. Where necessary to aid in access
along the perimeter of the pit or completed reservoir, the berms may be increased in
width to better facilitate the access of vehicles or heavy equipment. The height and
width of the berm will be field fit at the time of placement and will not go beyond permit
limits. While the berm width will vary, they will fit within the ten (10.0±) foot buffer
between the permit boundary and any planned extraction; and where wider, will
extend into the basin area conforming to 3H:1 V minimum outslopes. To the extent
possible, the height of berms will near five (5.0±) feet along the perimeter where a
residential structure is within 125.0± feet from active extraction operations. Soils
volumes extracted in excess of that needed for reclamation may be temporarily
stockpiled as part of the berms, elsewhere on -site, or conveyed to nearby Kurtz or
Heintzelman Projects, until sold as product. It should be understood that there is no
'overburden' at this location, as all materials are viable product or useful component
to the reclamation of affected lands and establishment of the desired end uses.
Subsequent to soil salvage, extraction of aggregate will commence. Extraction
utilizes, but is not limited to, diverse heavy equipment; including, scrapers,
excavators, dozers, backhoes, and related heavy equipment. The raw material will
be transported by heavy equipment or haul trucks to on -site plant facilities.

6.4.4 EXHIBIT D — Mining Plan
Any method that accelerates the operation timetable will be utilized, depending
upon market conditions and the capacities of the operator. To this end, an existing
conveyor system is established in the northeast comer of Tract A. Extracted
resource may be conveyed to or from other Raptor Materials off -site plant facilities.
One conveyor system and route are already established on the northwest corner
of the permit area and will convey materials to or from the Kurtz operation to the
North. A second conveyor route has been established along the west permit
boundary to facilitate movement of materials to and from the adjacent Heintzelman
operation; this conveyor extends onto the Bearson property, entering along the
southwestern border of Tract A. Processed and unprocessed or otherwise
Colorado Department of Health compliant inert materials may originate from
different sources and locations for import and utilization for our on -site processing
commercial, or reclamation interests; either as product in its unaltered state, or as
otherwise processed, recycled, or repurposed from on -site processing and
operations. All inert materials may arrive via conveyor or overland haulage.
While initial operations will commence on the north boundary of Tract A, both Tracts
A and B may be extracted concurrently. All extraction will proceed in a manner to
minimize visual and audible impacts to adjacent lands and properties. In Tracts A or
B, extraction will commence to facilitate removal of material from a nearby
residence and County Road 28 to better distance those locations from operations
over time; and to gain time to vacate or relocate any utilities, oil and gas lines, or
other structures from the interior of the tracts as needed, and in cooperation with
the owners or other responsible parties.
Extraction activities -will remove aggregate to a weighted average depth of 30.0+
feet from the surface. Anomalous depths greater than 50.0± feet may occur.
Temporary basin perimeter slopes created by extraction will conform to the
geotechnical analysis of Exhibit S. All final basin (reservoir) slopes will be
established concurrently with extraction and will conform to Rule 3.1.5(7), as
detailed under Exhibit E - Reclamation Plan.
Extraction, which occurs within the basin at a 1.25H:1V slope, is expected to be
complete within 5 to 7 years. Following extraction, slopes will be regraded at a
3H:1V slope. Currently, the entirety of the western wall, or 1,760± linear feet, has
been extracted and regraded. When fully extracted, there would be an estimated
9,357± linear feet remaining of wall perimeter that would need to be reclaimed in a
worst -case scenario An estimate of the remaining volume to be regraded is
provided by subtracting the volume of the finished, regraded basin (3,951,674± CY)
from the proposed extracted basin configuration (4,098,487± CY) for a total volume
to be regraded of 146,813± CY.
Soils encountered during extraction will vary over the location in depth and extent.
Actual soil variations, depths and descriptions, including potential volumes to be
extracted, are detailed in Exhibit I & J: Soils and Vegetation Information, and are

shown on Exhibit I & J: Soil and Vegetation Map. The soil volumes essential for
reclamation of affected lands remaining above the anticipated static water level
(4795'± elevation) of the completed basins will be salvaged and stockpiled from a
portion of the upper six inches of the native soil profile (the 'topsoil'). The remaining
soils found within the solum or generated by plant processing activities, and in
excess of that required for reclamation of affected lands, will be utilized for sale to
help satisfy the infrastructure and development demands of the surrounding
community.
As indicated in Exhibit E - Reclamation Plan; of the 111.05± acres of potential
extraction, the resulting basins will function as reservoirs with a water surface covering
90.10± acres. This leaves a balance of 20.95± acres of affected land within the
extracted basins above the anticipated static water level. When combined with 24.49±
acres of Mineral Reserve Area used for support operations, a potential 45.44± acres
may require resoiling and revegetation over the life of the operation. The maximum
45.44± acres is provided for under Exhibit L - Reclamation Costs.
The primary end use for the extracted basins is developed water resources, however,
the balance of lands remaining above the anticipated static water elevation of the
basins, and not otherwise occupied, will be later developed to the highest possible end -
use. End use may vary over the reclaimed lands and will comprise a variety of mixed
uses. Mixed use may include other agricultural uses; as well as light residential,
commercial, or industrial uses.
While the on -set of reclamation is concurrent with extraction, the completion of
reclamation may lag up to five (5.0±) years behind the onset of reclamation activities.
Completion of remaining extraction of the permit area is expected to take approximately
5-7 years, depending upon market conditions, with an additional 5 years following
completion of all extraction activities for ultimate completion of concurrent reclamation
activities, placing the completion of all activities near 2035-2040.

SUMMARY
OVERVIEW:
Summary Status of Affected and Unaffected land as of this Amendment (Exhibit C-1:
Existing Conditions and Exhibit C-2: Extraction Plan Map). The excavation has, prior to this
technical revision, been separated into two distinct pits. While maintaining the reference to
separate Tracts A (West Basin) and B (East Basin), it is anticipated that this will become one
large open extraction area that will be converted to a single lined reservoir upon completion
of mining. For the purpose of reclamation costs, the excavation and subsequent regraded
and lined reservoir is summarized as one pit:

RECLAMATION
EXPOSURE:
Based upon the Mining and Reclamation Plans of this application, the status and trend of
activities and affected land; and related calculations to estimate reclamation liability, are
determined as follows.
Please Note: Due to the difficulty of calculating heavy equipment costs similar to the
Division's software program, unit costs from previous and reasonably current Division
estimates of like or similar kind have been utilized to create a reasonably close estimate.
The per unit basis from Division records are shown along with other sources used or
referenced to determine unit costs, at the back of this exhibit.
DEWATERING:
Extraction started in Tract A in 2018 and is ongoing; extraction of Tract B began in 2021.
The formerly designated Mineral Reserve Area 1 between Tracts A and B will be extracted
as well, resulting in one large open extraction area within the permit boundary (see Exhibit
D). This estimate is for reclamation of the entirety of the planned extraction areas (formerly
Tract A, Tracts B, and Mineral Reserve Area 1) from a static water surface elevation with
maximum lateral inflow. The analysis computes the cost to dewater the full pit, and then
to dewater for one additional month while reclamation is completed.

Dewatering Estimate (refer to Two Rivers estimate utilizing similar pump and rates):
Initial pit dewatering:
518,901,425 gal x $ 0.000131/gal. •discharge cost = $67,976.09
Construction dewatering (one month):
131,760,000 gal x $ 0.0001/gal. discharge cost = $13,176.00
NOTE: Sufficient water resources exist to supplement basin losses in its unlined
state during operations. However, concurrent reclamation, which includes the
progressive lining of basin walls once extraction is complete, is ongoing, and the
final planned use of the pit is a developed water resource in the form of a lined
reservoir.
GRADING:
As stated in Exhibit D - Extraction Plan:
Extraction, which occurs within the basin at a 1.25H:1 V slope, is expected
to be complete within 5 to 7 years. Following extraction, slopes will be
regraded at a 3H:1V slope. Currently, the entirety of the western wall, or
1760± linear feet, has been extracted and regraded. When fully
extracted, there would be an estimated 9,357± linear feet remaining
of wall perimeter that would need to be reclaimed in a worst -case
scenario. An estimate of the remaining volume to be regraded is provided
by subtracting the volume of the finished, regraded basin (3,951,674± CY)
from the current basin configuration (4,098,487± CY) for a total volume to
be regraded of 146,813± CY.
Average push distance is 50± feet using equipment and assumptions leading to per unit

Raptor has made allowance for liner installation on the regraded slope. Assumptions are that a 4 -
foot -thick liner will be keyed into bedrock at the base of the regraded slope and up the slope to
approximately 5 feet below the original surface elevation. The western wall of the excavation has
already been regraded and lined and is therefore not included in the perimeter used in calculations
below. The remaining slopes have an average depth of 30 feet. The keyway dimensions in bedrock

Establishment of Vegetation over Affected Lands:
The demand for establishment of vegetation over the affected lands will also diminish
proportionately with the planned extraction of the Tracts. For now, the total exposure
is estimated as indicated above to be 45.44± acres at complete extraction (refer to resoil
area, above):
NOTE: The vegetation demand (and related costs) will decrease proportionately as
extraction activities increase over each Tract of planned extraction. The seed mixture

Processing Area and Decommissionina:
Raptor has estimated decommissioning costs for the Conveyor that will deliver mined material to that
area. Decommissioning will involve the removal of the conveyor infrastructure and belting.
The decommissioning cost estimate for the conveyor structure is based on previous estimates
provided by Divide Construction for other Raptor (previously Varra) operations and presented in
Financial Warranty estimates. The costs have been updated to current using US Army Corps of
Engineers Civil Works Construction Cost Index System (CWCCIS) indices.
The portion of the conveyor anticipated to be removed with the decommissioning of the P122 Pit
includes the portion present within the P122 Pit's property boundary, as well as the alignment along
the western property boundary (located within the P116 Pit's property), the elevated truss across
County Road 28, and the section that parallels County Road 17 northward until the limit of the P115
property. The total length of the regular conveyor structure in 40 -foot sections supported on concrete
blocks is estimated to be 3,412± lin.ft. with an additional extended span elevated truss section 125 -
foot in length that crosses County Road 28. The conveyor has a width of 3 feet and a height of 6 feet.
Decommissioning costs for the regular conveyor structure are estimated at $ 0.8/cu.ft. and for the
elevated truss section at $9.57/SF. Concrete block removal is estimated at $6.89/ea.
Concrete block removal: 3,412 lin.ft = (1 block/40 ft) x $6.89/ea = $592.54

Parcel 122 — Resource Development Project
DRMS Permit M-2015-033
Mr. Zuber,
This Technical Revision addresses the revised permit boundary for the Parcel 122
project, as approved in an Acreage Reduction (AR -01) by the DRMS on April 27, 2023,
and additional modifications to the extracted areas within said permit boundary.
The following modifications to the project area are included in this Technical Revision:
Reduction of the permit boundary by 0.92 acres from 156.78 acres to 155.86
acres;
Inclusion of the formerly designated Mineral Reserve Area 1 between Tracts A
and B in the Tract B extraction area (effectively connecting the two tracts as a
single excavation);
Addition of eight (8) former setback areas around oil and gas wells that are now
plugged and abandoned; and
Extension of approximately 470 linear feet of conveyor belt from existing
conveyor on the west adjacent Heintzelman property into the P122 Bearson
project area.
Based on the present phase of extraction, the life of mine is expected to be reduced,
with a current anticipated end date of reclamation of 2035-2040. An updated financial
warranty estimate is included based on the above -stated revisions.

This is a . plan of extraction of a valuable mineral resource for the processing,
stockpiling, and sale of essential construction materials to serve the needs .of the
areas urban and rural economic matrix and correlated infrastructure. The effects will
return the affected lands to developed water resources.
From the approved Colorado Office of Mined Land Reclamation (OMLR) permit,
Exhibit D Extraction Plan (Note: Acreages referenced herein have been updated
based upon subsequent OMLR approved Review):
On April 27, 2023, DRMS approved an Acreage _ Reduction (AR -01) of the permit from
156.78± acres by 0.92 acres to a new acreage within the permit boundary of 155.86±
acres. The 155.86± Acre permit boundary contains two areas of planned extraction
bounded by extraction limits and identified as Tract A - West Basin and Tract B - East
Basin. Each area of plannedextraction includes the following:
51.96±
59.09±
111.05±
Acres of Planned Extraction -Tract A- 5-15± years.
Acres of Planned Extraction - Tract B - 10-20± years.
Acres of Planned Extraction -TOTAL
The formerly designated Mineral Reserve Area 1 between Tracts A & B is now
included in the Tract B extraction area. While maintaining the reference to separate
Tracts A (West Basin) and B (East Basin), it is anticipated that this will become one
large open extraction area that will be converted to a single lined reservoir upon
completion of mining. Several areas set aside as setbacks from oil and gas wells now
plugged and abandoned are also now included in the extraction areas.
Of the remaining 44.81± acres of the permit boundary, 20.32± acres comprise
existing and permanent access roads, irrigation laterals, and setbacks or areas of
pre-existing, minor, to no disturbance. The southern 24.49± acres comprise a plant
processing and stockpile area, as well as a mineral reserve.
Extraction will not occur within the remaining Mineral Reserve Area until and unless
identified, detailed, and approval under a separate technical revision to the OMLR
permit. Until that time the remaining Mineral Reserve. Area may be used to support
both wet and dry plant operations and stockpiling of processed materials.
A portable scalehouse/office may also be located in the Mineral Reserve Area. The
actual location, extent, and facilities will be detailed and identified by location and
extent in a later technical revision to the original approved permit. No on -site storage
of fuels is planned as portable fuel (trucks) will service all heavy and correlated
operational equipment. An electrical line serving operations is not shown on included

maps as it is established by the operator, temporary, and subject to relocation in
cooperation with United Power Company. All other power and related overhead or
buried lines are outside of the influence of extraction activity or will otherwise be
relocated in cooperation with their owners or other responsible parties where they
conflict within the interior of planned extraction. Buried oil and gas lines are estimated,
and extraction and offset of operations are approximate and will be determined in the field
in cooperation with the Utility Notification Center of Colorado.
It should be noted that a homestead and yard with outbuildings subsequent to the
2023 Acreage Reduction now occupies 2.42± acres and acts to divide the north
central permit boundary. The access road leading to the homestead has an active
easement for operations which will be used as secondary access for light vehicles
and equipment. Immediately south of the residential yard, existing facilities prevent
the area from being used other than as a storage or parking area for vehicles,
equipment (including heavy equipment), supplies, or other operational support
purposes. This location is fully, disturbed by prior agricultural and landowner
purposes. This may also include theplacement or construction of storage structures
and materials.
The primary access for heavy equipment, servicevehicles, haul trucks and related traffic
is located along an established access road that traverses the east line of the permit
boundary. Both access roads intersect Weld County Road 28 that flanks the northern
extent of the permit boundary. A grader and water truck maintain access within the permit
area as necessary throughout operations.
The aggregate deposit varies in composition, depth and extent. Generally; depths are
shallower toward the southeast, trending deeper toward the northwest, and are consistent
with the gradient flow of groundwater which appears to be at stasis near elevation 4795
feet. Tract B (East Basin) falls from 15-45± feet and Tract A (West Basin) from 35-55±
feet from the surface to the underlying unconsolidated bottom. Unconsolidated suitably
derived on -site material may be used for diverse purposes, including commercial
products, or the re -grading of the extracted basin. These same materials may also be
used to line the completed basins (refer to Exhibit G - Water Resources, Part 6 for details
on how completed basins will be lined). The lined basins form the primary end use as a
developed water resource, and will be utilized accordingly.
To facilitate dry extraction of overburden and aggregate, groundwater will be discharged
from the areas of active extraction at one or more of the three designated discharge
locations identified on Exhibit C-2: Extraction Plan Map. Discharge of waters will be
conducted under an approved Colorado Dept. of Health discharge permit, as indicated
under Exhibit M - Other Permits.
The FEMA designated flood plain was severed in 1911 with the construction of the Union
Pacific railroad bed located approximately 1 mile to the west. While found within and

along the terminus of the upper terrace of the historic floodplain of St. Vrain Creek,
operations will not impact the active FEMA designated floodplain.
The general directionof extraction activities over the Tracts is from north to south, as
shown on Exhibit C-2 - Extraction Plan Map. No extraction will occur within
125 feet of a residential structure, or ten feet of any other structure, property
boundary, right-of-way, or easement without written agreement with the owner of said
structure. These' setbacks supersede any representation of the extraction limits
shown on Exhibit C-2: Extraction Plan Map.
Extraction activitieswill be limited to within 25.0± feet of well heads and facilities, and
those same wellheads will be backfilled to create a 100± foot radius around the well
head for future oil and gas activities at that well head. The fill around well heads will
occur concurrently with extraction around the well head and facilities, to the extent
practical. At all times, safety will take precedent and over -ride as necessary any
element of the permit to assure protection of life and property and compliance with
federal safety regulations (MSHA). Changes resulting from a safety consideration
that require a modification of the approved permit will be made after the fact
respective of amendment or technical revision provisions of the Office of Mined Land
Reclamation (OMLR).
Initially, heavy equipment (typically, scrapers, dozers, or excavators operating alone
or in combination) will extract soil, placing it along the basin perimeter in the
construction of up to a five (5.0±) foot high visual berm. The berm may vary in height
and width. Outslopes of the berm will be 3H:1 V or flatter to aid establishment of
grasses and utilizing the approved seed mixture. Where necessary to aid in access
along the perimeter of the pit or completed reservoir, the berms may be increased in
width to better facilitate the access of vehicles or heavy equipment. The height and
width of the berm will be field fit at the time of placement and will not go beyond permit
limits. While the berm width will vary, they will fit within the ten (10.0±) foot buffer
between the permit boundary and any planned extraction; and where wider, will
extend into the basin area. conforming to 3H:1V minimum outslopes. To the extent
possible, the height of berms will near five (5.0±) feet along the perimeter where a •
residential structure is within 125.0± feet from active extraction operations. Soils
volumes extracted in excess of that needed for reclamation may be temporarily
stockpiled as part of the berms, elsewhere on -site, or conveyed to nearby Kurtz or
Heintzelman Projects, until sold as product. It should be understood that there is no
'overburden' at this location, as all materials are viable product or useful component
to the reclamation of affected lands and establishment of the desired end uses.
Subsequent to soil salvage, extraction of aggregate will commence. Extraction
utilizes, but is not limited to, diverse heavy equipment; including, scrapers,
excavators, dozers, backhoes, and related heavy equipment. The raw material will
be transported by heavy equipment or haul trucks to on -site plant facilities.

Any method that accelerates the operation timetable will be utilized, depending
upon market conditions and the capacities of the operator. To this end, an existing
conveyor system is established in the northeast corner of Tract A. Extracted
resource may be conveyed to orfrom other Raptor Materials off -site plant facilities.
One conveyor system and route are already established on the northwest corner
of the permit area and will convey materials to or from the Kurtz operation to the
North. A second conveyor route has been established along the west permit
boundary to facilitate movement of materials to and from the adjacent Heintzelman
operation; this conveyor extends onto the Bearson property, entering along the
southwestern border of Tract A. Processed and unprocessed or otherwise
Colorado Department of Health compliant inert materials may originate from
different sources and locations for import and utilization for our on -site processing
commercial, or reclamation interests; either as product in its unaltered state, or as
otherwise processed, recycled, or repurposed from on -site processing and
operations. All inert materials may arrive via conveyor or overland haulage.
While initial operations will commence on the north boundary of Tract A, both Tracts
A and B may be extracted concurrently. All extraction will proceed in a manner to
minimize visual and audible impacts to adjacent lands and properties. In Tracts A or
B, extraction will commence to facilitate removal of material from a nearby
residence and County Road 28 to better distance those locations from operations
over time; and to gain time to vacate or relocate any utilities, oil and gas lines, or
other structures from the interior of the tracts as needed, and in cooperation with
the owners or other responsible parties.
Extraction activities -will remove aggregate to a weighted average depth of 30.0+
feet from the surface. Anomalous depths greater than 50.0± feet may occur.
Temporary basin perimeter slopes created by extraction will conform to the
geotechnical analysis of Exhibit S. All final basin (reservoir) slopes will be
established concurrently with extraction and will conform to Rule 3.1.5(7), as
detailed under Exhibit E - Reclamation Plan.
Extraction, which occurs within the basin at a 1.25H:1 V slope, is expected to be
complete within 5 to 7 years. Following extraction, slopes, will be regraded at a
3H:1 V slope. Currently, the entirety of the western wall, or 1,760± linear feet, has
been extracted and regraded. An estimate of the remaining volume to be regraded
is provided by subtracting the volume of the finished, regraded basin (3,951,674±
CY) from the proposed extracted basin configuration (4,098,487± CY) for a total
volume to be regraded.of 146,813± CY.
Soils encountered during extraction will vary over the location in depth and extent.
Actual soil variations, depths and descriptions, including potential volumes to be
extracted, are detailed in Exhibit I & J: Soils and Vegetation Information, and are
shown on Exhibit I & J: Soil and Vegetation Map. The soil volumes essential for
reclamation of affected lands remaining above the anticipated static water_ level

(4795'± elevation) of the completed basins will be salvaged and stockpiled from a
.portion of the upper six inches of the native soil profile (the 'topsoil'). The remaining
soils found within the solum or generated by plant processing activities, and in
excess of that required for reclamation of affected lands, will be utilized for sale to
help satisfy the infrastructure and development demands of the surrounding
community.
As indicated in Exhibit E - Reclamation Plan; of the 111.05± acres of potential
extraction, the resulting basins will function as reservoirs with a water surface covering
90.10± acres. This leaves a balance of 20.95± acres of affected land within the
extracted basins above the anticipated static water level. When combined with 24.49±
acres of Mineral Reserve Area used for support operations, a potential 45.44± acres
may require resoiling and revegetation over the life of the operation. The maximum
45.44± acres is provided for under Exhibit L - Reclamation Costs.
The primary end use for the extracted basins is developed water resources, however,
the balance of lands remaining above the anticipated static water elevation of the
basins, and not otherwise occupied, will be later developed to the highest possible end -
use. End use may vary over the reclaimed lands and will comprise a variety of mixed
uses. Mixed use may include other agricultural uses; as well as light residential,
commercial, or industrial uses.
While the on -set of reclamation is concurrent with extraction, the completion of
reclamation may lag up to five (5.0±) years behind the onset of reclamation activities.
Completion of remaining extraction of the permit area is expected to take approximately
5-7 years, depending upon market conditions, with an additional 5 years following
completion of all extraction activities for ultimate completion of concurrent reclamation
activities, placing thecompletion of all activities near 2035-2040.

6.4.4 EXHIBIT E — Reclamation Plan
This application provides substantial detail of features by utilizing
aerial photography ortho-rectified to near survey accuracy. This highly
accurate and detailed portrayal of the mining and reclamation is visible
under Exhibit . C-1: Existing Conditions Map, Exhibit C-2: Extraction Plan
Map, and Exhibit F - Reclamation Map. How reclamation will occur over
affected lands is further detailed under Exhibit L - Reclamation Costs.
As extraction progresses over planned areas in Tracts A and B; the resulting
slopes created during extraction (refer to Exhibit D - Extraction Plan) will be
concurrently modified by pushing the resulting pit bottom with a dozer until the
resulting basin slopes conform with Rule 3.1.5(7). Lands above the anticipated
final water level of the basins and within I0.0± feet below the anticipated final
water level of the basins will be graded to 3H:1V, or flatter. Lands below
I0.0± feet from the anticipated final water level of the basins will also be graded
to 3H:1 V, or flatter. Naturally occurring slopes may exceed 2H:1 V where not
otherwise affected by extraction activities and will not be altered as part of
reclamation unless necessary to facilitate the reclamation of affected lands.
A Backfill Notice is included with this application as an Addendum at the back
of Exhibit E - Reclamation Plan, to facilitate the use of inert fill over portions of
the extracted lands to accomplish final end -use potentials, reservoir storage,
and other mixed uses, which may include residential, commercial or industrial
structures or uses otherwise approved now or in the future by Weld County,
Colorado. The extent and natureof the reservoir represents the maximum
build -out respective of optimal extraction of commercial product and resulting
final slopes.
All affected lands remaining above the anticipated high water mark of the
finished reservoirs will be capped with a minimum of six 6.0± inches of soil,
as supported by Exhibit I & J - Soils and Vegetation Information. Timing
and use of soil is detailed further under Exhibit I & J - Soils and Vegetation
Information and Exhibit L - Reclamation Costs. Where compacted lands
requiring revegetation exist, those locations will be ripped prior to re -soil
application. There are no known areas of compaction at- the time of this
application which would require such activity; however, provision for an
estimated 25 percent of revegetated land is estimated to require ripping prior
to seeding based on prior experience.
The final land configuration resulting from completed extraction will create the
Primary End Use of Developed Water Resources, forming one reservoir basin
totaling 111.05± surface acres as shown on Exhibit F: Reclamation Map. The
reservoir will have a water surface area of 90.10± acres at full build out.

6.4.4 EXHIBIT E — Reclamation Plan
Since the existing lands comprised predominantly of crops, ornamental, or
introduced species; disturbed lands remaining above the static water level of
the basins (4790' elevation), will be revegetated with an enduring stabilizing
coverof predominantly native grasses (refer to Exhibit E - Table E-1:
Primary/Preferred Re -vegetation Seed Mixture). An optional seed mixture is
provided under Exhibit E - Table E-2: Optional/Default Revegetation Seed
Mixture. This optional mixture provides for the. use of other genetic potential
and species combinations under failed 'conditions consistent with the seed
mixture utilized over the pre- disturbed lands. A wheat x wheatgrass sterile
hybrid will be combined with either applied mixture as a substitute for the use
of mulch to aid establishment of newly seeded areas.
The target for release of revegetated lands is based upon the establishment
of a stabilizing cover of predominantly native vegetation whose foliar umbrella
equals or exceeds 25 percent of the total area of the ground as measured one
inch above the native soil on a square meter basis for typical areas of
reclaimed cover achieved within five years subsequent to the completion of all
extraction activities. Lands not otherwise occupied for use as Developed
Water Resources will be later developed to the highest possible end -use, and
will likely comprise mixed agricultural, light residential, commercial or
industrial uses.
Mixed use(s), may also include, but are not limited to: the retention of existing
structures as desired (e.g., portable or fixed concrete batch plant, asphalt batch
plants, recycling facilities and related structures, shop, scale-house/office; and
supporting facilities such as fuel depots, parking areas., oil and gas facilities
access, etc.) for continued industrial - commercial uses; the creation of
unforeseen future structures, and for the use and development of on -site water
resources. Since the area of surrounding lands is a mix of these uses, the site
end use will retain these potentials.
The rate of reclamation activity, including grading, soiling and revegetation will
follow concurrently with extraction and the respective timetables identified for
extraction under Exhibit D - Mining Plan. All timetables are contingent upon
market conditions. With extraction activities anticipated to take up to 5-7 years
to complete, reclamation will add approximately five years to this estimate,
bringing the anticipated life of the mine to 15-20± years, or the year 2035-40.
The actual end point is five (5.0±) years subsequent to the completion of all
recoverable materials and successful release of all reclamation required under
the approved State of Colorado Division of Reclamation Mining and Safety
(DRMS) permit.

SUMMARY
OVERVIEW:
Summary. Status of Affected and Unaffected land as of this Amendment (Exhibit C-1:
Existing Conditions and Exhibit C-2: Extraction Plan Map). The excavation has, prior to this
technical revision, been separated into two distinct pits. While maintaining the reference to
separate Tracts A (West Basin) "and B (East Basin), it is anticipated that this will become one
large open extraction area that will be converted to a single lined reservoir upon completion
of mining. For the purpose of reclamation costs, the excavation and subsequent regraded
and lined reservoir is summarized as one pit:

RECLAMATION
EXPOSURE:
Based upon the Mining and Reclamation Plans of this application, the status and trend of
activities and affected land; and related calculations to estimate reclamation liability, are
determined as follows.
Please Note: Due to the difficulty of calculating heavy equipment costs similar to the
Division's software program, unit costs from previous and reasonably current Division
estimates of like or similar kind have been utilized to create a reasonably close estimate.
The per unit basis from Division records are shown along with other sources used or
referenced to determine unit costs, at the back of this exhibit.
DEWATERING:.
Extraction started in Tract A in 2018 and is ongoing; extraction of Tract B began in 2021.
The formerly designated Mineral Reserve Area 1 between Tracts A and B will be extracted
as well, resulting in one large open extraction area within the permit boundary (see -Exhibit
D). This estimate is for reclamation of the entirety of the planned extraction areas (formerly
Tract A, Tracts B, and Mineral Reserve Area 1) from a static water surface elevation with
maximum lateral inflow. The analysis computes the cost to dewater the full pit, and then
to dewater for one additional month while reclamation is completed.

Dewatering Estimate (refer to Two Rivers estimate utilizing similar pump and rates):
Initial pit dewatering:
518,901,425 gal x $.0.000131/gal. discharge cost = $67,976.09
Construction dewatering (one month):
131,760,000 gal x $ 0.0001 /gal. discharge cost = $13,176.00
NOTE: Sufficient water resources exist to supplement basin losses in its unlined
state during operations. However, concurrent reclamation, which includes the
progressive lining of basin walls once extraction is,complete, is ongoing, and the
final planned use of the pit is a developed water resource in the form of a lined
reservoir.
GRADING:
As stated in Exhibit D - Extraction Plan:
Extraction, which occurs within the basin at a 1.25H:1V slope, is expected
to be complete within 5 to 7 years. Following extraction, slopes will be
regraded at a 3H:1V slope. Currently, the entirety of the western wall, or
1760± linear feet, has been extracted and regraded. An estimate of the
remaining volume to be regraded is provided by subtracting the volume
of the finished, regraded basin (3,951,674± CY) from the current basin
configuration (4,098,487± CY) for a total volume to be regraded of
146,813± CY.
Average push distance is 50± feet using equipment and assumptions leading to per unit

foot -thick liner will be keyed into bedrock at the base of the regraded slope and up the slope to
approximately 5 feet below the original surface elevation. The western wall of the excavation has
already been regraded and lined and is therefore not included in the perimeter used in calculations
below. The remaining slopes have an average depth of 30 feet. The keyway dimensions in bedrock
are assumed to be 4x4 -foot.
Perimeter liner at 9,357 lin.ft. x 40 sq.ft./ft x _4 ft. / 27 = 55,476 CY of liner placed at an estimated
cost of $1.302/CY = $ 72,229.70.
Keyway at the base of the 3:1 slope is estimated at 8,830 lin.ft. x 16 sq.ft./ft / 27 = 5,233 CY of liner
placed an estimated cost of $2=1.302/CY = $6,812.84.
$ 79,042.53 Total Liner Installation Cost
Soil Demand AND Re -soiling of Affected Lands (refer to Exhibit D):
NOTE: The soil demand (and related costs) will decrease proportionately as extraction
activities progress over each Tract of planned extraction as a result of concurrent
reclamation. For now, a conservative area estimate to reclaim the lands above the static
water level of the entire extraction area will be determined for resoiling expenses.

Establishment. of Vegetation over Affected Lands:
The demand for establishment of vegetation over the affected lands will also diminish
proportionately with the planned extraction of the Tracts. For now, the total exposure
isestimated as indicated above to be 45.44± acres at complete extraction (refer to resoil
area, above):
NOTE: The vegetation demand (and related costs) will decrease proportionately as
extraction activities increase over each Tract of planned extraction. The seed mixture

Processing Area and Decommissioning:
Raptor has estimated decommissioning costs for the Conveyor that will deliver mined material to that
area. Decommissioning will involve the removal of the conveyor infrastructure and belting. .
The decommissioning cost estimate for the conveyor structure is based on previous estimates
provided by Divide Construction for other Raptor (previously Varra) operations and presented in
Financial Warranty estimates. The costs have been updated to current using US Army Corps of
Engineers Civil Works Construction Cost Index System (CWCCIS) indices.
The portion of the conveyor anticipated to be removed with the decommissioning of the P122 Pit
includes the portion present within the P122 Pit's property boundary, as well as the alignment along
the western property boundary (located within the P116 Pit's property), the elevated truss across
County Road 28, and the section that parallels County Road 17 northward until the limit of the P115
property. The total length of the regular conveyor structure in 40 -foot sections supported on concrete
blocks is estimated to be 3,521± lin.ft. with an additional extended span elevated truss. section 125 -
foot in length that crosses County Road 28. The conveyor has a width of 3 feet and -a hight of 6 feet.
Decommissioning costs for the regular conveyor structureare estimated at $ 0.8/cu.ft. and for the
elevated truss section at $9.57/SF. Concrete block removal is estimated at &6.89/ea.
Concrete block removal: 3,521 lin.ft = (1 block/40 ft) x $6.89/ea = $613.21
Conveyor decommissioning: 3,521± lin.ft. x 18 sq.ft x $ 0.80/cu.ft. = $ 50,702.40

Demolition of Structures: None. Building Permits for structures will be obtained where
required from the Weld County Building Department.
Please Note: The per unit cost values derived from previous OMLR determinations
for heavy equipment, as applied to this exhibit, are included at the back of this
exhibit. Since there is no possibility of the applicant in fully reproducing the
Division's methods, utilizing similarities from past OMLR calculations is the most
viable and accurate means available for the applicant to derive reasonable
estimates of per unit costs and should result in estimates very reliable with that of
the Division.

permitted lands of 155.86± acres upon release. This is unaffected land that

As required, the existing Mining and Reclamation Maps will be updated to
reflect the change in the permit boundary following release of the area. No
