5 <br /> Evaluation of Hydraulic and Hydrochemical Aspects of Proposed <br /> Bulkhead - Sunnyside Mine <br /> 1. Page 14 , First Paragraph <br /> What is the basis of the assumption that rock in the mine <br /> vicinity has an average of 1% pyrite? Is the amount of <br /> pyrite relevant given the information that ground water flow <br /> is believed to be entirely within fracture? <br /> 2 . Page 16 <br /> This section should indicate whether there are any ore zones <br /> at depth. If so, do these zones have major water flow <br /> through them? Figure 6 should be labeled to identify the <br /> major veins depicted on the figure. <br /> 3 . Page 18 <br /> This report and the hydrology report suffers from the <br /> absence of a map and cross sections showing both tunnels and <br /> the mine workings . The fact that the water was 50 feet <br /> below the F level in 1959 means nothing without some good <br /> figures . Additionally, it is not clear how the authors <br /> determined that the 1959 static water level was deep enough <br /> that minor joints would be closed. The basis for such a <br /> claim at this location is unverified. <br /> 4 . Page 22 <br /> It is proposed to place a bulkhead in the American Tunnel <br /> near the underground property line with the Gold King <br /> property. The report on hydrology indicates this will <br /> intercept all water which originates on the SGC property. <br /> Given the nature of fracture flow, the certainty of such a <br /> statement is questionable. Water could very well originate <br /> on the SGC property and enter the tunnel at some distance <br /> beyond the property line. <br /> 5 . Page 24 , Second Paragraph <br /> This section refers to on-going reclamation work in the <br /> Sunnyside Basin which may reduce mine inflow. The nature of <br /> this work is not described. <br /> 6 . Page 24 , Second and Third Paragraphs <br /> The report indicates that the water table may stabilize at <br /> 11, 500 feet (provided that inflow from Lake Emma is stopped, <br /> which appears questionable) . The report neglects, however, <br />
