Sorenson: <br /> Each numbered issue presented below corresponds to the numbered <br /> concern as expressed by the Division of Minerals and Geology <br /> (Division) in the attached April 15, 1993 , TR-14 adequacy concern <br /> letter . 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 /> 1 . 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 outb e 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 footages" 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 AT-P3 . AT- <br /> P3 is 145 feet outbye of the hardrock contact (brow) at <br /> the portal . <br />
