The estimated affected lands within the May Day Mine area include approximately <br />four acres. <br />16. Please clarify the contradiction between Section 6.3.3(1)0, which <br />indicates that the three acre area of existing disturbances will not be <br />enlarged, and Section 6.3.3(1)(e), which states that the exiting bench at <br />Level 2 will be extended. Please specify the dimension of the extended <br />bench at Level 2 as required by Rule 6.3.3(1)0. <br />Response to Adequacy Issue No. 16: Wildcat Mining will disturb the <br />areas identified in Attachment 15. <br />17. Section 63.3(1)(h) ofAM-01 states, "The water source will be from the water that is <br />present in the underground workings at the Mayday-Idaho Mining complex and <br />from the Idaho augmentation ponds .... " Please identify all locations <br />underground where such water sources exist. Additionally, please clarify <br />whether ground water will be pumped from these underground water sources <br />and if so, please describe and illustrate how this will occur. <br />Response to Adequacy Issue No. 17: Wildcat Mining will extract 15 gpm from an <br />existing well located adjacent to the May Day Mine, the Thompson Well, or suitable <br />alternative. Water will be pumped on an as needed basis and trucked to the May Day Mine <br />for use at the May Day No. 1, No. 2 and the Lamb (May Day No. 3). The Thompson Well <br />was permitted and completed in 1972. Wildcat Mining's processing and fugitive dust <br />consumptive use will be approximately 10 gpm. See Attachment 4. <br />18. The requirements of Rules 6.3.3(1)(i), 3.1.6, 3.1.7, 63.3(1)(k), 63.3(1)(1), and <br />63.3(1)(m) are not fully addressed.

Section 6.3.3(1)(o) of AM-01 indicates that explosives will be utilized <br />underground, provides a summary of information required for blasting reports, and <br />commits to conducting pre-blast surveys for all structures located within 0. S mile of the <br />proposed shot. Attachment C-7 contains a letter from Franklin Drilling and Blasting, <br />Inc., dated February 24, 2010, and a statement from Terry Morris Engineering, which <br />is not signed or dated. Please note that engineering reports must be signed and dated by <br />the qualified person who prepared the report. If the qualified person who prepared the <br />report is a professional engineer, such report should bear the certification statement and <br />seal from that licensed individual. Additionally, the statements from Franklin Drilling <br />and Blasting and Terry Morris Engineering discuss the effects of underground blasting <br />at depths of 1, 000 feet or greater, but do not address the potential effects of blasting at or
