• Mr. Allen Sorenson, DRMS 3/6/2009 Page 4 of 4 <br />cobalt, iron, manganese and zinc standard, with a lower pH boundary than the <br />Agricultural Standard. Those particular elements have a reduced proposed baseline <br />standard than was presented in TR05, based on 99% upper confidence calculation (lower <br />bound in the case of pH). <br />• Downgradient Well (MW-5) was drilled and completed on or about September 27, 2007 <br />and as such has only four quarters of data available. A revised provisional baseline was <br />calculated for the available dataset, with only manganese exceeding the Colorado <br />Agricultural Standard (by less than an order of magnitude). A provisional baseline is <br />proposed in Table 4. MRV suggests that, per TR05, a permanent baseline be established <br />upon receipt of five (5) quarters of data. <br />3. Impacts to Surface and/or Groundwater <br />There were no negative effects observed on either surface or groundwater within the past year. <br />Only small variations in parameter concentrations were measured showing that there are little to <br />no effect on water from MRV's operation. MRV expects, based on field data, that the water <br />quality within the Cash Mine will improve, following mill tailings emplacement per the proposed <br />Technical Revision #06. <br />4. Mitigation Measures <br />At this time, no mitigation measures appear necessary. <br />Please do not hesitate to contact us at (720) 565-3448 for any questions or concerns the Division <br />may have. <br />Sincerely, <br />MOUNT ROYALE VENTURES, LLC <br /> <br />By: Matt Collins <br />General Manager - Front Range Gold Project <br />Enclosures: <br />¦ Table 1- Cash Gulch (SW-1) Summary and Baseline Analysis <br />¦ Table 2 - Upgradient Well (MW-1) Summary and Baseline Analysis <br />¦ Table 3 - Cash Mine Pool (CW) Summary and Baseline Analysis <br />¦ Table 4 - Downgradient Well (MW-5) Summary and Baseline Analysis <br />¦ Inorganic Analytical Results - ACZ Laboratories, Inc. - data for all water <br />monitoring performed by MRV per permit requirements, from Q1, 2006 to <br />Q3, 2008, inclusive (additional data prior to April 10, 2007 predates <br />requirements for water monitoring under this permit, but is included in <br />dataset) <br />2007-8 Mine Water.doc
