Whetstone Associates is in the process of preparing that report. Since <br />our meeting last November, we have installed and sampled downgradient monitoring well MW- <br />12 and performed an electrical conductivity survey of Ralston Creek. This information, along <br />with summaries of all available historical water quality data, will be provided in the EPP. <br />We are requesting a 30-day extension for the submission of the EPP, to allow sufficient time to <br />finalize the data compilation and allow Cotter Corporation sufficient time to review the <br />document. We understand DRMS's desire to receive the EPP and move toward Designated <br />Mining Operation (DMO) status for the Schwartzwalder, and will do our best to work with you <br />in this process. <br />Sincerely, <br />Whetstone Associates, Inc. <br />Susan A.
