4' <br />• <br /> <br />Memo to Tom Schreiner 3 Julv 1, 2002 <br />eAfl~ i~h <br />w <br />0 <br />0 <br />N <br />The total volume of rock to be removed to create the required benches in the example above is <br />1,779,000 bank cubic yards (BCY). Assuming a cost for blasting and rock disposal at $2.SOBCY, you <br />can see that the bonding requirement for benching may be substantial. Once actual quantity take-offs <br />aze determined based on the mine plan and any concurrent benching commitments the Operator is <br />willing to make, asite-specific cost estimate can be completed using the DMG's CIRCES cost <br />estimating softwaze. <br />Finally, as a point of clarification, page 6 of the REVEY Report states that the average strike of the <br />north dipping gneiss foliation is "N 127° E." The way this is written, it appeazs to refer to a bearing; <br />however, reference to Figure 4.3 from the REVEY Report shows that the direction is in fact an <br />azimuth of 127°. If this azimuth were to be expressed as a bearing, it would be S53°E. <br />
