EXHIBIT D - Mining Plan We intend to continue excavation at the level in the existing excavated area within the pit limits. In general it is approximately six to ten feet below ground surface. The material will be used as fill materials for construction sites in and around Alamosa. The materials are for the most part alkali sands. The sand has high bearing capacity and is generally free draining which makes it an excellent material for fill at building sites. The excavated face will be worked with a loader from North to South. Trucks will run on the excavated level. No water diversions will be necessary due to the low precipitation in the area, the free draining nature of the soils in the area, and the flat gradient of the land in and around Alamosa. If the average depth of available material is six feet then one acre will yield approximately 10,000 cubic yards of available fill material. The demand for this material is very hard to estimate. It is totally dependent upon local growth and the building market. If past years are any indicator it is estimated that enough material is in the pit to supply the needs for approximately the next ten years. It is hoped that reclamation can proceed on at least a portion of previously mined areas as the mining process continues. Since truck traffic and loading operations will occur on the previously mined areas at least some portion will remain disturbed until final reclamation. This source will operate less than 180 days per year. An estimate of the site and location of each phase is impossible to forecast since at this time the magnitude and quantities for materials needed from this source are unknown. Mining will proceed from North to South starting on the northeast portion of the property which has already been mined and is currently being used as an illegal dumping ground by persons unknown. This area will be cleaned up prior to commencing mining operations.
