EXHIBIT B ' Mining Plan The current operator of this clay mine began his operation in ' 1956. The area mined since 1976 is indicated on the mining plan map. Production quantities for the years 1973-1976 were used to deter- , mine area projection required for the mining plan. They are as follows; 1973 - 11,334 Tons t 1974 - 13,220 Tons 1975 - 8,198 Tons ' 1976 - 19,293 Tons The operator has indicated a projected reco very rate of ap proximately ' 16,000 tons per year. The average overburden is 63% comprised primarily of 1 foot of to soil u nderlain by 40-50 feet of clay interbeded with sand- ' stone lenses. "Maximum pit depths are in the 55 foot range and typically are less than 40 feet. Using a 40 foot average depth and a 53% overburden value, it is projected that one to one and one-h alf surface acres per year will be disturbed. Less than one-hal f acre of additional land is occupied by haul reads ' and stock outs. The mining plan will consist of topsoil removal by dozers and the stockpiling of the topsoil. Some drilling and blasting of the sandstone nn Ir~ ' ' overburden may be required prior to its removal. It is anticipated that I~ the stock out area for topsoil can be established in previously mined areas ' The pit will be excavated to an approximate maximum depth of 55 feet by front ' end loader which places the material in dump trucks for delivery to a processing site in Pueblo operated by Summit Brick Co. No +aater usage is ' anticipated at the mine site and no surface or ground water is retained except for shoe°t periods after heavy rains. th i A i d i d s e m n ng progresses, an the topsoil can be red stribute , it will be redistributed according to the reclamation plan~s'ted later. Mining operations at this pit are intermittent occurring not more
