BROWNSTONE QUARRY 112 MINING PLAN F,XHTRTT n The current 1 a0 mining permit (M-97-065) is being converted to a 112 mining permit. The approach to the plan has not changed much except for mining a ridge of different sandstone to the east from the existing permitted disturbed area. The real difference is the amount of'room that became necessary to stockpile finished product and rubble. To affectively achieve an efficient approach, we found it necessary to place some of our rubble out of 1:he permitted area. Permission was granted from Bill Porter, the landowner. With the 112 ;permit we will screen these rubble areas for sellable material and stockpile the fines for reclamation using netting and planting grass as specified. The demand for this stone has continued to increase as well as our continued ability to utilize material that was considered waste in the early stages of operation. Another result of these factors is we had to retrace our steps and extract valuable material from the areas that had already been reclaimed on the north of the current quarry permit. Carl Mount's inspection report noted this on 4-23-01. The proposed mining area toward the east of the existing disturbance will not be disturbed until we have reclaimed 50 % or greater of the existing 4 acres of disturbance. This is a different color and grade of stone than the brownstone that may not prove to be economically viable yet we feel it has potential. The maximum area of disturbance is not expected to exceed the current 4 acres. We will follow a stepped approach to reclamation, as we complete the culling process, beginning with the farthE;st north portion of the existing disturbance to the south. We will reclaim in approximately 100 foot stages north to south and the full width east to west. This culling process is novv in progress and we will have the first 100 foot phase of reclamation under way by mid summer 2007. We will accomplish this by backfilling, grading and seeding as per the reclamation plan. Rain water rwming south from the area north of the irrigation ditch has historically funneled dovv~n to a span of about 50 feet as it approaches the irrigation ditch. This span will be controlled, adjacent to the bridge that crosses the ditch, by both bales of straw and silt fencing. This ditch is for flood stage only and runs on an occasional basis. The approximate timetable for the quarry is about 25 to 40 years life of the mine with reclamation stages running in about 6 to 10 months increments or longer if demand and unforeseen changes occur. This portion of the narrative we choose to remain confidential. The deposits run in layers that are at approximately 25 to 30 degrees from horizontal. The top layer of sandstone is about 12 to 15~ feet thick then a second layer of unsellable clay is about 10 feet thick. Below this clay is another layer of sandstone about 12 feet thick that we discovered after beginning operations in 1997. Below the second sandstone layer is another clay layer about 20 feet 1:hick. A third layer of sandstone lays below this clay layer. This deposit is a minimum of 5~0 feet thick and will be enough stone to last for the 25 to 40 projected years life of the quarry. The products from the sandstone in this deposit will be the same as we currently produce. We prepare and sell veneers, dimension stone (cap and patio stone etc.) decorative drywall and saw blocks. We intend to hire a custom crushing company from time to time
