Discussion of each item or Sub-issue under that numbered <br /> concern is provided by Sunnyside Gold Corporation (SGC) along with <br /> any clarifications required of. the Divisions perception based <br /> Previous correspondence as well as SGC' s proposals for addressing <br /> the issues. Since partial approval of TR-14 for construction of <br /> the Brenneman bulkheads is approved, conditioned upon meeting <br /> construction specifications and other agreed upon conditions, this <br /> letter primarily focuses upon the American Tunnel and Terry Tunnel <br /> bulkheads. <br /> I. Continuing Discharge After Bulkhead Placement <br /> a) American Tunnel bulkhead location <br /> The proposed location of the American Tunnel bulkhead in <br /> relation to Sunnyside Mine workings and the flow <br /> Proportion originating out bye of the proposed site, <br /> property not owned by Sunnyside Gold, is clarified below. <br /> The Simon Hydro-Search report (February 11, 1992) <br /> references "track repair footages" as marked on the wall <br /> of the American Tunnel and the TR-14 submittal refers to <br /> the American Tunnel bulkhead site as being "approximately <br /> 7950 feet from the portal". These location references <br /> are not the same. The "track repair foot-ages" are <br /> painted numbers on the rib of the American Tunnel used by <br /> the track crew during operation for visual orientation or <br /> reference. They do not correlate to actual distances <br /> from any reference point. The 7950 foot distance in the <br /> TR-14 submittal is based on SGC survey point 4T-P3. AT- <br /> P3 is 145 feet outbye of the hardrock contact (brow) at <br /> the portal . <br />
