Mount Royale Ventures, LLC <br />Post Office Box 1523 <br />Longmont, Colorado 80502 <br />Telephone (303) 443-0318 <br />Facsimile (303) 442-2&48 <br />February 20, 2006 <br />Mr. Thomas A. Schreiner <br />Environmental Protection Specialist <br />Division of Minerals and Geology <br />1313 Sherman Street -Room 215 <br />Denver, Colorado 80203 <br />RECE)VE® <br />FEB 2 0 2006 <br />Uirision ~f Minerals end Geology <br />RE: Cash Mine (Permit M-1983-141; Amendment No. Z) C/qsS ~ iSevisfon <br />Response to 2n° Adequacy Review Comments TPe-Seg ~ri1-2- <br />Dear Mr. Schreiner: <br />Mount Royale Ventures, LLC (MRV) herein provides supplemental information in <br />response to the remaining adequacy response comments contained within the Division's <br />letter of February 15, 2006. Items are addressed in the same sequence put forth in that <br />letter. <br />5. Re: Proposed sampling plan for material pertinent to the Designated Mining <br />Operation (DMO) status determination. <br />MRV will commit to the submittal (in the form of a Technical Revision) of a <br />comprehensive sampling and analysis plan to evaluate the site's DMO status as <br />pertaining to the acid generating potential (AGP) of vein and wall rock materials. <br />MRV requests that the Cash Mine AGP Analysis Plan (Technical Revision) be <br />submitted to the Division not later than 60-days following conditional approval of <br />Amendment No. 2, with sampling commencing coincident with approval of said <br />Technical Revision. The sampling period would be carried out over atwelve-month <br />period; interpretation of results and presentation of mitigating measures, if warranted, <br />would be completed not later than six-months thereafter. <br />MRV envisions that the Technical Revision will encompass representative sampling <br />of vein and wall rock materials (to include both hanging wall and footwall), utilization <br />of Acid Base Accounting (ABA) analytical procedures, and interpretation of data <br />utilizing recognized methodologies. If such materials are found to exhibit acid <br />generating potential, MRV reserves the right to assess the degree of acid generating <br />potential within the context of proposed operations, and appropriately incorporate <br />materials management procedures and/or other measures to preclude DMO status. <br />In the event significant AGP is indicated, non-DMO status would be contingent on <br />satisfactorily demonstrating to the Division that such materials can be adequately <br />managed or isolated from producing adverse environmental affects over the long- <br />term. <br />
