SUNNYSIDE GOLD CORPORATION <br /> MLR PERMIT FILE NO. M-77-378, TR-14 <br /> SEEP INVENTORY AND MONITORING PROGRAM <br /> UPDATED 6/1/96 <br /> A. Purpose <br /> Sunnyside Gold Corporation (SGC) has submitted a Mined Land <br /> Reclamation (MLR) Permit Technical Revision (TR-14) to the <br /> Division of Minerals and Geology (DMG) . TR-14 provides <br /> technical details to implement the conceptual plan contained <br /> in the permit to eliminate Sunnyside Mine drainage from the <br /> Terry and American Tunnels. This will be accomplished by <br /> installation of concrete bulkheads in the tunnels. <br /> SGC, through the DMG TR approval process, was required to <br /> address a list of concerns prepared by DMG (April 15, 1993) . <br /> Item 2 of this list of concerns required; <br /> 1) an inventory of the vicinity of the workings to be <br /> flooded to establish background data on seeps, springs <br /> and flowing adits for conditions prior to valve closure <br /> and monitor for changes after valve closure. <br /> Modifications to DMG's initial (April 15, 1993) general <br /> study outline requirements have been made through <br /> subsequent communication and agreement between SGC and <br /> DMG. <br /> 2) that SGC report on the feasibility of using groundwater <br /> tracers. <br /> SGC subsequently performed the feasibility study and <br /> committed to inoculating the Sunnyside Mine with bromide <br /> (tracer) and monitoring for bromide at identified <br /> monitoring sites. SGC has since been released from this <br /> commitment due to the potential of introducing toxicity <br /> to State waters. Stream monitoring will continue to <br /> detect abnormal flow or metal levels. <br /> B. Scope <br /> I. Seep, Springs and Adit Flow Inventory <br /> 1.
