Tailings will be hauled directly to the Revenue Pile but will use County Road 26 to a new bridge <br />across Sneffels Creek to reach the Atlas Pile. This pile has no threat of avalanches due to the terrain <br />above it. No avalanche has been seen there in over 100 years. <br />A shallow well, called Well 1, will be placed on the north (downhill side) of the Atlas waste <br />rock/tailings pile as shown on Map C -3 and C -4. This Well will evaluate the chemistry of any water <br />leaching from the tailings and waste rock pile. The Revenue waste rock/tailings pile will have two <br />wells installed. Well 2 will measure water at the base of the existing waste rock and Well 3 will be <br />installed in the new tailings that will be built over the existing waste rock at the Revenue Pile. In <br />this manner, the Revenue tailings and the existing Revenue waste rock can be monitored separately. <br />A cross section of these wells in the Revenue waste rock/tailings pile is given on Map C -6. <br />These wells will be sampled quarterly for field parameters of temperature, pH, conductivity and <br />water level. Samples will also be tested with full suite analysis using the same parameters of the <br />ground water suite for all recent pre -mine samples. The results of these tests and their evaluation <br />will be incorporated in the Quarterly Report and Annual Reports which will be submitted to the <br />Division within 30 days of the receipt of the lab results in each quarter. Also, sample test data from <br />any sediment pond discharges will be evaluated in the Annual Report. <br />If, during any sample of pond discharge or well, a low pH is detected or any other issue is found, <br />the Division will be immediately notified. <br />All of these steps will ensure that the tailings placed on site will be inert and will be reclaimed to a <br />stable condition that will never have any problems once the mine is reclaimed. <br />b) Waste Rock <br />Waste rock currently exists at the Revenue Pile from driving the Revenue Tunnel (and other side <br />tunnels) over 100 years ago in the inert host rock (andesite) in order to access the veins. <br />Additionally, it is expected that new waste rock will be produced at the rate of approximately <br />Revenue Mine August 2012 T -17 <br />
