3 <br /> 6 . Page 21, Second Paragraph <br /> A map showing the seep locations is needed. How many seeps <br /> and springs are located in both Cement Creek and Eureka <br /> Gulch? Data on the actual flow (and associated quality) out <br /> of the Silver Lodge Mine and the Big Colorado Mine is not <br /> provided. This information is essential for a credible <br /> evaluation of the proposal . <br /> 7. Page 22 , First Paragraph <br /> This paragraph indicates that prior to mining the ground <br /> water would have contained an anomalous metal content <br /> because of the oxidation of sulfides along fractures . I <br /> seriously question this premise. This section raises <br /> several questions. What is the source of oxygen oxidation <br /> if the fracture systems are full (as they would be in <br /> premining conditions) ? The extensive limonitic staining <br /> mentioned would be related to flow in and out of the upper <br /> portion of highly fractured mineralized zones . Is there <br /> unstated evidence to support an oxidation mechanism for <br /> deeper fracture flow? Although some of the surface <br /> fractures in sulfide rich areas fill and drain in response <br /> to precipitation events, most of the fracture systems would <br /> have been full of water most of the time. This would limit <br /> the oxidation of sulfides in contact with water in those <br /> fractures . Although the oxidation of sulfides connected to <br /> the drainable fractures would affect surface water quality, <br /> I question how significantly this would have affected deeper <br /> ground water. <br /> S . Page 22 , Second Paragraph <br /> What is the basis of the statement that ground water from <br /> Fault #1 and Fault #2 has traversed a greater distance from <br /> the recharge area than the other faults? These faults could <br /> have intersected zones containing more mineralization. <br /> Information on the flow out of each of the measured zones <br /> should be provided to give a picture of the actual load <br /> which is a more meaningful criteria. <br /> 9 . Page 25 , Third Paragraph <br /> Information on the flow from the bog near the Mogul Mine and <br /> on the flow out of the mine should be included to give a <br /> clearer picture of what is going on at the mine. The actual <br /> water quality at both points should also be provided. <br />
