EXHIBIT B <br />' Mining Plan <br />' The current operator of this clay mine began his operation in 1971. The <br />area mined since 1976 is indicated on the mining plan map. <br />Production quantities for the years 1973-1976 were used to determine area <br />projection required for the mi <br />' 1973 <br />1974 <br />' 1975 <br />1976 <br />ling plan. They are as follows <br />- 6298 Tons <br />- 3800 Tons <br />- 1585 Tons <br />- 2067 Tons <br />The operator has indicated z projected recovery rate of approximately <br />3440 tons per year. The average overburden is 84'6 comprised primarily cf 1 <br />' foot of topsoil underlain by an average of 14.5 feet of sandstone and 34 feet <br />of soft clay. Maximum pit depths are on the order of 35 feet. At the above <br />' recovery rate it is projected that one to ene and one-half surface acres per <br />t year will be disturbed. <br />' ~ail.ding.~~0n@ ars;.~e~~t~:V,~;.#t:t would not require disturbance of additional <br />acreage as those are spoil products of clay mining, No mining of these ma- <br />' terials per se has taken place znd none have been marketed to date. <br />T~'~#:~~.an will .,'~ ~'" .. ,~;,,;,..:.Stogk- ~ <br />' pi~R~~,st~il.

No water usage is anticipated at the mine site and little surface or <br />,' ground water is retained except for short periods after heavy rains. <br /> <br />
