As discussed in that meeting, Powertech is requesting that the Colorado Division of <br />Reclamation and Mining Safety (DBMS) reevaluate the direct costs associated with the bond <br />calculation for exploration activities proposed and approved, pending bond placement, for the <br />Modification to the Notice of Intent (NOI) File Number P-2008-043. <br />During the meeting it was agreed by DBMS and Powertech that the proper abandonment of the <br />drill holes, i.e., fully protective of groundwater resources, will be accomplished by pumping a <br />high quality sodium bentonite gel from the bottom of the drill hole to 13 feet below the ground <br />surface. In addition, a Portland Type I cement will be used from the 3-13 foot interval and the <br />remaining 3 feet below ground surface will be backfilled with native soil. Powertech requests <br />that the DBMS adjust the surety bond calculation to reflect this compliant abandonment <br />procedure. <br />It was also agreed during this meeting that the DBMS would consider actual documented costs <br />incurred by Powertech in their reevaluation of the bond calculation for abandonment of drill <br />holes. In order to reevaluate the surety bond estimate, it was requested by the DBMS that <br />Powertech provide actual invoices and daily drilling logs associated with abandonment activities. <br />They are attached to this report. Actual costs include those for the plugging and abandonment of <br />drill holes, backfilling and replacement of topsoil in mud pits, and equipment travel between drill <br />pads. Powertech has not provided any actual costs for vegetation reclamation activities for mud <br />pits and drill pads, and are not contesting the bond estimate provided by the DBMS for these <br />costs, because the DBMS estimate appears to be commensurate with actual costs incurred by <br />Powertech for vegetation reclamation. <br />To aid the DBMS in their evaluation, please find the enclosed attachments. <br />5575 DTC Parkway, Suite 140 Telephone: 303-790-7528 Website: <br />Greenwood Village, CO 80111 USA Facsimile: 303-790-3885 Email: <br />
