<br /> <br />Other assumptions are as follows: <br />1. All mining and processing will be done with portable equipment. A $50,000 figure is assumed <br />to be sufficient to remove the conveyor support structures, the fuel storage containment area, <br />and any other miscellaneous, as the portable systems and any left equipment DMG would <br />recover any other costs of removal through the sale of salvageable equipment. <br />2. No fencing is proposed to be removed, as access to the property will continue to be limited. <br />3. Unit prices are assumed to reflect current market conditions and include contractor overhead <br />and profit. A five percent administrative contingency for the DMG to adminster the work is <br />added to the cost estimate. <br />Based on the preceding, the estimated costs for reclamation bonding are calculated below: <br />ESTIMATED COSTS FOR RECLAMATION BONDIlVG <br />Ac ivi <br />Approximate <br />Am un Uni <br />Unit Total <br />Cost ost <br />Replace 20% of slurry wall to 20% x 35' depth x 14,168 LF <br />$3.00 $ 297,528 <br />i meet State Engineer's leakage <br /> criteria.
