During our conversation, you stated the Department <br /> of Minerals and Geology (DMG) will approve the technical revision with the stipulation that four <br /> monitoring wells be sampled. The existing wells do not meet the needs of monitoring wells due <br /> to the depth of the wells. Based on the existing well logs, the first aquifer is at approximately 50 <br /> feet below the surface. The shallowest existing well is approximately 220 feet. <br /> Based on the current conditions described above, Mining and Minerals II, Ltd. proposes to install <br /> two shallow monitoring wells: one upstream of the project disturbance and one downstream at ft <br /> permit boundary. In addition,Mining and Minerals 11, Ltd. will monitor two of the existing wells. <br /> This letter and the enclosed map provide approximate locations for the two shallow monitoring <br /> wells and the two existing wells proposed for monitoring. <br /> We will contact a local drilling company and proceed with installation following approval by the <br /> DMG for the Dr000sed wells locations. <br /> Should you have any questions, please contact Mr. Bruce Cloud at (210) 299-1100 or myself at <br /> (702) 738-2265. <br /> Sincerely, <br /> KNIGHT PIESOLD LLC <br /> Richard A.
