Response to Geochemistry Review - May Day Conversion CN-1 <br />File No. M-1981-185 <br />Adequacy Issue #20 <br />A. Attachment T-7, Mine Rock Geochemical Analysis. Please comment on the <br />representativeness of the rock subjected to SPLP testing, i.e., the location(s) from within <br />the mine the rock was collected. <br />B. The ANP: AGP ratio is only 1.14 to 1, and represents only one sample. Considering that <br />this ratio does not provide an overwhelming proportion of acid-neutralizing material, in <br />conjunction with the fact that date from only one sample have been provided, the <br />Division requires more comprehensive static testing of material that could ultimately be <br />disturbed, exposed, and/or stockpiled. This will begin the establishment of a data set and <br />screening parameters for possible future kinetic testing. Please provide a plan for more <br />comprehensive sampling and static testing, to be implemented subsequent to the issuance <br />of CN-01. <br />Response #20 <br />The mine rock geochemical sampling plan and protocols are presented in Attachment T-7. <br />The sample was obtained from of mine rock from the May Day No. 1 stope. The SPLP test <br />was conducted on May Day No 1 ore that is currently stockpiled on the bench. Additional <br />SPLP and static tests will be conducted on representative materials are collected in the <br />future Currently tests are slated to be performed every 5000 tons of run of mine rock until <br />representative whole rock chemistry is quantified and approval from DRMS to terminate <br />the sampling program. <br />If there are any questions or comments regarding the submitted materials please contact: <br />Mr. George Robinson-Agent <br />Wildcat Mining Corporation <br />5555 DTC Parkway, Suite 4000-A <br />Greenwood Village, CO 80111 <br />George M.L.
