The average soil and overburden stripped from the area is determined from the drill holes con- <br />ducted by United. These holes and average values aze shown below: <br />• <br />Area 1 <br />Hole # SoiUOverburden <br />Depth Gravel Thickness Total Depth <br />21 1.5 21.0 22.5 <br />22 3.5 20.0 23.5 <br />23 2.0 21.0 23.0 <br />24 3.0 21.5 24.5 <br />25 7.0 15.0 22.0 <br />31 9.0 I5.0 24.0 <br />32 9.5 13.5 23.0 <br />33 8.0 14.5 22.5 <br />34 7.0 17.0 24.0 <br />35 7.0 17.0 24.0 <br />36 5.5 18.5 24.0 <br />37 5.0 20.0 25.0 <br />38 5.0 20.0 25.0 <br />39 7.5 18.5 26.0 <br />Average 5.8 18.0 23.8 <br />Since the top 1.0 ft. will have been placed in the stockpile, the average overburden thickness of <br />4.75 feet will need to be removed. Since storage space is limited, the overburden from only 6.0 <br />acres will be removed initially, then the gravel will be mined and the overburden from the remain- <br />der of the area will be stored in the 6.0 acres that has been mined out. In this way, a lazge amount of <br />overburden does not need to be initially stored out of the pit azea. The total soiUoverburden from <br />t 5 Road Pit t 0/02 <br />
