RE: Amendment to DMG Regular Operation 112 Permit Application
Applicant: Andesite Rock Company
Operation: Phillip Camenisch Resource, Weld County
SW '/4, and the S '/2 of the SE '/4, Section 10, T2N, R68W

To Ti-:__ -..
Rule 1.8 in the Mineral Rules and Regulations of the Division of Minerals and Geology (DMG)
requires that we inform your office of any changes in a Regular 112 Operation permit application
(sand and gravel mine). Tuttle Applegate, as the applicant's representative, is filing a request with
DMG to amend the above permit application. The original application was submitted to DMG on
October 10, 1997, and deemed sufficient on October 17, 1997. Notification was sent to your office.
The decision date is set for January 15, 1998, and we would like to keep this date if possible.
The two changes proposed in the application amendment are interrelated. Change #1 is to remove
six acres from the northern mining boundary of Phase 1B (from 23 acres to 17 acres), as shown in
the revised Mining Plan. Change #2 is to move the relocation site for Idaho Creek further to the
south, adjacent to the new mining boundary for Phase 1B.
These changes require some minor revisions to the original application. The number of permitted
acres in Item Three on the Reclamation Permit Application Form changes from 243 to 237 total
permitted acres. Only three of the exhibits in the original application are altered by these changes:
Exhibit C (Mining Plan map), Exhibit D (Mining Plan), and Exhibit F (Reclamation Plan map).
Copies of the three revised exhibits are enclosed with this letter.
Please feel free to contact us if you need further information.
Sincerely,
TUTTLE APPLEGATE, INC.

EXHIBIT D
Mining Plan
The Phil Camenisch is a significant commercial deposit of sands and gravels located in alluvium
of St. Vrain Creek in Weld County. This area of the County is well known for mining
operations. There are current or past mining operations on both the west and north sides. The
east and south sides are in agricultural uses.
The permit boundary includes 240 acres. Of this approximately 183 acres will be mined in three
phases. The acreage per phase is as follows:
Phase 1 — 60 acres
Phase 2 — 90 acres
Phase 3 — 33 acres
Phase 1 of the mining is on the west side of the site and mining will proceed eastward over the
years. The digging of the clarifying ponds will produce sand and gravel. This material will be
stored until the processing plant is running.
The duration of this mining operation is eight to fourteen years. The operator expects to
excavate from 10 to 15 acres per year. This would be a continuous mining operation with no
cessation planned. By the end of 2012 the mining will be complete and reclamation will be
completed within two years.
There will be a minimum of a 25 foot setback for mining operations from all property lines. The
minimum setback from the rural ditch is 100 feet.
The site contains several physical constraints which have influenced the mining operation.
Access to the site is gained from Weld County Road 7 on the west side. Therefore, the access
road and the plant site is located on the westerly part of the property. The Rural Ditch diagonally
crosses the property on its eastern side. In addition, there are wetlands, natural gas facilities, and
the landowner's house which influenced the configuration of the mining.
The mining operation will progress as follows:
A. Construct the access road into the site.
B. Build a wetland mitigation area, relocate Idaho Creek, dig the initial dewatering
trenches, and start the dewatering pump.
C. Construct the processing plant area, the clarifying ponds, and the office/scale area.
D. Build a secondary access road on the south side.
E. Strip topsoil and overburden from the Phase 1A land.
F. Set out the field conveyor from the first excavation area to the processing plant.
G. Commence mining of the resource in Phase 1A & the processing of the aggregate.
H. Set up the concrete batch plant.
I. Continue with mining over the property
D-1
Mining will then proceed to the north into Phase 1B. Then we expect that the plant site will be
relocated into the Phase 1B pit area and Phase 1C of ten acres will be mined. As noted on
Exhibit C, the clarifying ponds have future locations to the south of their noted location. Then
mining will progress into Phases 2 and 3.
All mining will occur by using a dry mining technique. There are eight possible pump locations
noted on the plan. The groundwater will be used to replenish the clarifying ponds, and provide
for water for other consumptive uses during the operation, with the remainder being discharged
into Idaho Creek. Idaho Creek will carry the water to the St. Vrain Creek which is
approximately one mile away.
The processing plant area contains the crushing and screening equipment for the raw material.
Some of the material will be washed for use in the concrete plant on the site. An asphalt plant
may also be located on -site and will use the material. Recycling is becoming an accepted
method of operation in the asphalt industry. Therefore, we will have a plant here to reprocess
both concrete and asphalt.
The following equipment and facilities will be utilized in this operation:
Loaders (3)
Feeders (3)
Screens (2)
Generators (2)
Crushers (2)
Conveyors (20)
Bottled Water Scraper (1) Aggregate Wash Plant (1)
Fuel Truck (1) Fuel Tank (1) Electric Control Van (1)
Mechanic Truck (1) Staking Conveyor (3) Asphalt Batch Plant (1)
Portable Toilets (3) Dozer (1) Concrete Batch Plant (1)
Scale (1) Road Grader (1) Ready Mix Concrete Trucks
Haul Trucks (4) Office Trailer (1) Excavator (1)
In order to gain an understanding of the extent of the mining operation, it is helpful to know the
acres disturbed by different aspects of the mine. We have selected a point in time where the
mining disturbance could be at its maximum. This occurs during the mining of Phase 1B. Here
the dewatering ditch will be at its maximum length. There is enough shoreline under reclamation
in Phase l A so that some lands may even be released. The following acres of disturbance apply
to this site:
Active Mining
Topsoil and overburden stockpiles
Stripped ground prior to mining
Processing Plants
Clarifying ponds
Access road
Office and Scale area
Graded and seeding areas
Reseeding due to 25% non -germination
Total Disturbed Area

The sand and gravel deposit varies from 10 to 15 feet in depth. The overburden and topsoil vary
in thickness from one foot to six feet. Bedrock under the deposit is shale.
The sand and gravel is the primary mineral produced. Principal intended use of the mine
products is construction aggregates. These aggregates will be sold to customers and included in
the concrete and asphalt plants on site.
