1 <br />EXHIBIT B <br />Mining Plan <br /> <br />1 <br /> <br /> <br /> <br /> <br /> <br /> <br />1 <br /> <br /> <br /> <br />t <br /> <br /> <br /> <br /> <br />The current operator of this clay mine began his operation in 1956. <br />The area mined since 1976 is indicated on the mining plan map. <br />Production quantities for the years 1973-1976 were used to determine <br />area projection required for the mining plan. They are as follows: <br />1973 - 4,044 Tons <br />1974 - 3,131 Tons <br />1975 - 0 Tons <br />1976 - 3,100 Tons <br />The operator has indicated a projected recovery rate of approximately <br />3,500 tons per year. The average overburden is 80% comprised primarily of <br />9" of topsoil underlain by 125 feet of sandstone and 25 feet of clay. Max- <br />imum pit depths are in the 150 foot range. Using a 150 foot average depth <br />and an 80% overburden value, it is projected that one to ene and one-half <br />surface acres per year will be disturbed. <br />Less than one-half acre of additional land is occupied by haul rocks <br />and stock outs. <br />The mining plan will consist of topsoil removal by dozers and the <br />stockpiling of the topsoil. Occasional blasting may be required to break <br />up a sandstone cap before it can be removed and stockpiled for later use <br />as fill. It is anticipated that the stock out area for topsoil can be <br />established in previously mined areas. The clay will be excavated to an <br />approximate maximum depth of 125 feet by front end loaders which places <br />the material in dump trucks for delivery to a processing site in Pueblo <br />operated by Summit Brick Co. No water usage is anticipated at the mine <br />site and no surface or ground water is retained except for short periods <br />after heavy rains. <br />As the mining progresses, and the topsoil can be redistributed, it <br />will be redistributed according to the reclamation plan sited later herein. <br /> <br />
