Exhibit C - Mining Plan Mining will done during the operating months, as weather permits, between May 15, 1991 through April, 1994. The affected area during mining will be 7.3 acres. The total pit area will be approx. 260' x 450' x 50' max depth. The first area mined will be approx. 150' x 390' x 50' max depth; please see Mining Map. This first phase is located in the existing depression from previous placer operations. The waste material, that which will not be sold as aggregate, from this phase will be placed in two existing intermediate bench areas as noted on the map. These benches are open areas that do not conform to the adjacent bank contour. All excavated material will be classified and stock piled for sale as aggregate as per the Mining Lease requires. The stock piles will be located in the same area as the existing aggregate stock piles, please refer to map. These stock piles are not expected to reach large quantities as sale of aggregate will occur concurrently with mining operations. The second area of excavation is approx. 105' x 450' x 50' max. depth. This phase of the pit is located under the existing ridge of waste placer material. The existing waste material will be back filled into phase one after it's completion. When phase two is cpmpleted, it will be backfilled, sloped, and rounded to the proper slope. As this has been a historically mined area, no additional roads will need to be constructed. All acess roads are in existance. Also, because all the land within the proposed permit boundaries has been mined or disturbed, there is no soil or plant growth on the property. This Land is a rock pile. A settling pond area of 150' x 120' x 15' depth will be constructed to settle the water used from the operation. This settled water will be pumped into a recirculation pond area of 120' x 35' x 10' depth to be recirculated for plant use. All gold extraction will be by means of sorting and washing the gravel. No leaching or chemicals will occur on the property. All water used in the operation will be supplied, as per noted in the mining lease, by the 4cfs of the Platte City Mining Ditch. No water will be released off property. No run off is expected due to the high permeability of the gravel. No disturbance to the hydrolic balance will occur. No ground water will be encountered. All applicable State water laws and regulations will be complied with.
