Wally Erickson <br />June 28, 2010 <br />Page 17 <br />28-5. Section 6.3.3(1)(1). The sum of the whole rock analysis (Table C-2) for the "Type 1 <br />- May Day" sample accounts for about 15 grams, or about 1.5% of the total mass of <br />the sample. Is the balance of the mass available in the whole rock data? As a QA <br />measure, DRMS would also like to see acid-base accounting (ABA) performed on <br />these rock samples. Please ensure that the spatial and volumetric representation of <br />the sampling is adequate. Also please provide more details on what the sample <br />represents (location of sample, date and method of sample, etc.) <br />Response to Adequacy Issue No. 28-5: A composite mine rock sample collected <br />from a stockpile located on the bench near the May Day Portal No. 1 as reported to Wildcat <br />Mining Corporation in a letter dated June 24, 2010 (Appendix 1 B). This report includes <br />sample location and photographs. Whole rock analyses was undertaken by X-ray <br />fluorescence (XRF) and reported in Table 1 of Appendix 1 B. The whole rock analysis <br />produced a result of 96.9% when reported as oxides (Section 2.1 of Appendix IB) When <br />carbonate was included (Table 2, Appendix B), approximately 100% of the total mass was <br />accounted for. Acid-Base accounting was undertaken and reported in Table 2 and <br />discussed in Section 2.2 of Appendix B. <br />28-6. Section 63.3(1)(i). Table 3 in the Christensen report indicates that several different <br />types of sulfide minerals are present, even though the Applicant submitted test <br />results indicating sulfur was not detected. In the event that suffidic material is <br />encountered during the mining operation, DRMS would like the Applicant to submit <br />at least one sample of the sulfidic material for testing, including ABA, whole rock <br />analysis, and accelerated weathering (e.g., SPLP), to provide an assessment of the <br />extent to which the suffidic material may leach to the environment. The DRMS <br />geochemist or other technical staff should be present during this sampling event. <br />Response to Adequacy Issue No. 28-6: A composite mine rock sample collected <br />from a stockpile located on the bench near the May Day Portal No. 1 as reported to Wildcat <br />Mining Corporation in a letter dated June 24, 2010 (Appendix 1B). Sulfide was analyzed <br />by both XRF (Table 1) and High Temperature Furnace Combustion (Table 2) with <br />concentrations being less than 2%. Acid-Base accounting was undertaken and reported in <br />Table 2 of Appendix 1B, indicating that the mine rock is potentially acid neutralizing <br />(Section 3.0, Appendix 1 B). As mining progresses, these analyses will be included in <br />incorporated into the mine program and the DRMS will be notified if sulfide minerals are <br />suspected. <br />28-7. Section 63.3(1)(i). Tables C-3 and C-4. Please provide more details on what the <br />samples represent and where they were collected. <br />Response to Adequacy Issue No. 28-7: Data from the May 2010 field work <br />described in 2) above will replace the data submitted in the Wildcat's Application as <br />follows:
