' 1967. The area mined since 1976 is indicated on the mining plan map.
Production quantities for the years 1913-1976 were used to determine
' area projection required for the mining plan. They are as follows:
1973 - 13,222 Tons
' 1474 - 18,821 Tons
1975 - 8,184 Tons
1976 - 11,634 Tons
The operator has indicated a projected recovery rate of approximately
12,200 Tons per year. The average overburden is 58% comprised primarily
of 4 feet of topsoil underlain by 10 feet of sandstone and 10 feet of
' clay. Maximum pit depths are in the 25 foot range and typically are less
than 20 feet. Using a 20 foot average depth and a 58% overburden value,
it is projected that one to two and one-half surface acres per year will
' be disturbed.
Less than one-half acre of additional land is occupied by haul roads
and stock outs.
The mining plan will consist of topsoil removal by dozers and the
' stockpiling of the topsoil. Some blasting may be required to break up the
' sandstone cap prior to its removal. It is anticipated that the stack out area
for topsoil can be established in previously mined areas. The clay will
' be excavated to an approximate maximum depth of 25 feet by front end
loader which places the material in dump trucks for delivery to a pro-
site

' is anticipated at the mine site and no surface or ground water is
retained except for short periods after heavy rains. Mining operations at
' this pit are intermittant and occur not more than 90 days of the year and

only as this clay type is needed by the rick factory in their operations.
