EXHIBIT D — MINING PLAN The operation proposes to extract rock from the existing permitted area by the owner Telluride Regional Airport Authority (TRAA) for use as building stone and landscape blocks. The operation anticipates starting on July 15, 2012. The existing permitted area is 10.5 acres. The permitted area will be apportioned into 4 quadrants of approximately 2.625 acres each, with the dividing lines running north to south in the middle of the area and east to west in the middle of the area. The 50 foot setback along the southern edge of the permitted area will remain undisturbed as it is presently, to maintain minimal visual impact. TSC intends to begin mining with the North East quadrant. The topsoil will be removed and stored along the south 50 foot setback of the South West quadrant. The overburden will then be removed and placed to the east of the stored topsoil. The staging area which includes our stone splitters, generators and processing equipment will be moved to the west which will be located at the center of the permitted area. The extracted rock will be placed in windrows to the west of the splitters. Stockpiles may be established for incidental rubble that is hauled off site and processed by others for gravel. These stockpiles will be established between the southern permit boundary and the pit area, near the topsoil and overburden. Packaging materials and finished palletized stone will be placed to the north of the processing area, behind a berm. TSC will excavate or mine to a depth not to exceed 50 feet. TSC will begin excavating and mining approximately 2 acres in the North East quadrant. The mining cycle includes topsoil removal, removal of overburden material, mining of the sandstone layer, re- filling the mined pit and completing the reclamation. As the operator completes approximately 1 acre of mining, it will fill and compact the mined area with a series of lifts of waste rock and overburden. This acre will then be contoured, topsoil applied and reclaimed in accordance with the attached reclamation plan. At that time, one adjoining acre, either to the west or to the south of the originally excavated 2 acres, will be excavated and mined. The direction of mining, either south or west, will be undetermined until the quality of the mined stone is determined.
