<br />J <br />processing in the mill, and the segregated waste rock will be <br />used for extending the tailings dam embankment. At the <br />completion of the white Cloud mine dump sorting and upgrading <br />operation, approximately 90 percent-of the material will have <br />been removed from its present location. <br />The ~F/ynona ,mine dump has a total tonnage of approximately <br />10,006'=hens of material. Sampling has shown that at least <br />~~,-000- ons of this waste dump material can be raised to ore <br />grades material by sorting and simple upgrading. Most of the <br />Wynona mine-dump will be used to construct the initial starter <br />dam of the talilings embankment, while the ore grade material <br />will be stockpiled south of the Wynona mine shaft. Approxi- <br />mately 90 percent of the Wynona mine dump material will be <br />removed from its present location for use as borrow material <br />and ore for the mill. Removal and production will commence on <br />the northeastern portion of the Wynona mine dump, between the <br />Oscar mine shaft and the Wynona mine shaft. This operation <br />will proceed south along the southern face of the mine dump. <br />A small front-end loader and dump truck will be used to remove <br />the borrow material on the White Cloud and Wynona mine dumps. <br />A vibrating screen and conveyor will be used to sort and <br />upgrade the waste dump vein material selected for processing <br />in the mill. Mine dump production is based on a two-man crew, <br />which will result in the production of 20 tons of ore per day <br />for a total of 6,000 tons of dump material per year. The <br />amount of mine dump material is limited, and the sorting <br />operation and production are not expected to extend beyond one <br />and a half years.

These ores <br />will consist of gold-silver tellurides, <br />and various combinations of gold-silver- <br />lead-zinc-copper sulfides. <br />~:~ In order to process both <br />sulfide ores, the mill has <br />as a composite system of <br />flotation concentration. <br />~. / <br />telluride and / <br />been designed ~~~/// <br />gravity and <br /> <br />3. ~ Initial mill capacity will not exceed 50 <br />tons of ore in a 24 hour period. <br />4. The mill will not be operated as a custom <br />milling facility, and it will not process <br />ores on a toll basis for other mining <br />operations. <br />The Gold Hill Ventures Limited Partnership is currently <br />operating the Cash mine, which has sufficient proven ore <br />reserves to sustain this milling operation through 1988. In <br />the event that additional ore reserves are developed at depth <br />or along extensions of the Cash and Who Do mines, the proposed <br />mill could be in operation through 1995.' <br />Of special significance to the viability of this project is <br />the availability of waste dump material near the proposed <br />-6- <br />
