Exhibit D- Mining Plan
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 to 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):
The 156.78± 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:
50.36± Acres of Planned Extraction — Tract A — OS -15± years.
46.13± Acres of Planned Extraction — Tract B — 10-30± years.
96.49± Acres of Planned Extraction — TOTAL
Of the remaining 60.29± acres of the permit boundary, 26.29± acres comprise
existing and permanent access roads, irrigation laterals, operational
support/mineral reserve areas, and setbacks or areas of pre-existing, minor, to no
disturbance. The remainder includes a 10.00± acre Mineral Reserve Area (1)
between Tracts A and B, and an additional 24.00± acre Mineral Reserve Area (2)
to its south.
Extraction will not occur within the Mineral Reserve Areas until and unless
identified, detailed, and approval under a separate technical revision to the OMLR
permit. Until that time the Mineral Reserve Areas will be used to support both wet
and dry plant operations and stockpiling of processed materials. An existing basin
(created by previous agricultural activity) within the 10.00± acre Mineral Reserve
Area (1) will be utilized as a wash pond to support all on -site plant/processing
activities.
A portable scalehouse/office may also be located in the Mineral Reserve Areas.
The actual location, extent, and facilities will be detailed and identified by location
an 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. A_ 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,
Varra Companies, Inc. OMLR 112 Permit Application
Parcel 122 — Resource Development Project 20 April 2017

Exhibit D- Mining Plan
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 occupies 1.50±
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 35-60± 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, if
lined). Whether lined or unlined, the basins form the primary end use as 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.

Exhibit D- Mining Plan
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.
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 or from other Varra Companies, Inc. off -site plant
facilities. One conveyor system and route is 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 mute may be established (subsequent to an
approved OMLR technical revision) along the west permit boundary to facilitate
movement of materials to and from the adjacent Heintzelman operation. 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 39.0±
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

Exhibit D- Mining Plan
established concurrently with extraction and will conform to Rule 3.1.5(7),as
detailed under Exhibit E — Reclamation Plan.
Initially a 1600E foot extraction front will advance along its east -west orientation
from the northern extraction limit toward the southern permit boundary. The
advancing front will be comprised of side slopes of nearly 400 linear feet along
each side of an 811 foot i .25 :1 V advancing wall Concurrent reclamation will
trail this front by approximately 400 foot increments. This front is approximate for
all active Tracts. As the basin floor and perimeter boundary is reached, final
grading may commence once a minimum area of approximately four acres (or a
distance of 400 linear feet square) is attained. Finished slopes will be established
along the basin perimeter utilizing fill material taken from the basin bottom. If
Tract B opens concurrently at some point in time with Tract A, as per Exhibit I. Warranty Costs, additional warranty may be applied to include the second
advancing extraction front.
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 & 3: 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 96.49± acres of potential
extraction, the resulting basins will function as reservoirs with a water surface
covering S9.37t acres. This heaves a balance of 7.12± acres (4.06± acres West
Basin & 3.06± acres East Basin) of affected land within the extracted basins above
the anticipated static water level. When combined with 34.00± acres of Mineral
Reserve Areas used for support operations, a potential 41.12+ acres may require
resoiling and revegetation over the life of the operation.
Initial resoiling and revegetation burdens are actually far less, since full build out
takes up to 30-35 years to complete. Tract A (West Basin) at full build out has
4.3Q± acres of affected land within the extracted basin and above the anticipated
Varra Companies, Inc. oMLR 112 Permit Application 6
Parcel 122 — Resource Development Project 20 April 2017
Exhibit D- Mining Plan
static water level at the completion of aperattons. Since the 24.00± acres Mineral
Reserve Area (2) will not be affected until and unless the 10.00± acres Mineral
Reserve Area (I) becomes crowded or extracted. The initial area requiring
resoiling and revegetation for the full build out of Tract A and disturbance to the
10.00± acres Mineral Reserve Area (1) is 14.3f1± acres, and 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 welt as tight 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. Complete extraction of the permit area is expected to take
approximately 25-30 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
2045-2050, depending upon the date of start-up.

Exhibit E — Reclamation Plan
6.4.5 EXHIBIT E - Reclamation Plan
(1) In preparing the Reclamation Plan, the Operator/Applicant should be specific in
terms of addressing such items as final grading (including drainage), seeding,
fertilizing, revegetation (trees, shrubs, etc.), and topsoiling. 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.
(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;
(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;
(c) A description of how the Reclamation Plan will be implemented to meet
each applicable requirement of Section 3.1;
(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, forts, 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;
(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 Subparagraph 6.4.4(1)(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;
(ii) A description of the size and location of each area to be reclaimed
during each phase; and
(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.)
(fl A description of each of the following:
Varra Companies, Inc. OMLR 112 Permit Application
Parcel 122 — Resource Development Project 20 April 2017

Exhibit E — Reclamation Plan
(i) Final grading - specify maximum anticipated slope gradient or
expected ranges thereof;
(ii) Seeding - specify types, mixtures, quantities, and expected time(s)
of seeding and planting;
(iii) Fertilization - if applicable, specify types, mixtures, quantities and
time of application;
(iv) Revegetation - specify types of trees, shrubs, etc., quantities, size
and location; and
(v) Topsoiling - specify anticipated minimum depth or range of depths
for those areas where topsoil will be replaced.
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 3H:1 V
or flatter slopes created during extraction 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 lO.Ot feet below the anticipated final water level of the basins will be
graded to 3H:1 V, or flatter. Lands below 10.0 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 nature of 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
Varra Companies, Inc. OMLR 112 Permit Application

Exhibit E — Rec lama on Plan
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; and
ripping remains a contingency of the application.
The final land configuration resulting from completed extraction will create the
Primary End Use of Developed Water Resources, forming two reservoir basins
totaling 96.49± surface acres as shown on Exhibit F: Reclamation Map. The West
Basin of Tract A comprises 50.36± acres and will create a surface water area of
46.30± acres at full build out. The East Basin of Tract B is 46.13± acres and will
create a surface water area of 43.07± acres at full build out.
Since the existing lands comprised predominantly of crops, ornamental, or
introduced species; disturbed lands remaining above the static water level of the
basins (4795' elevation), will be revegetated with an enduring stabilizing cover of
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 fueldepots, parking areas, oil and gas facilities access,
etc.) for continued industrial - commercial uses; the creation of unforeseen future

Exhibit E — Reclamation Plan
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 25-30 years
to complete, reclamation will add an approximately five years to this estimate,
bringing the anticipated life of the mine to 25-30± years, or the year 2045-50. 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 (DBMS) permit.
A Backfill Notice follows this page, as part of this Exhibit. The use of inert fill
will facilitate the timely fill of selected portions of the project areas, and related
reclamation of affected lands and use of related water resources (refer to Exhibit L
Reclamation Costs).
