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 Whitei Cloud mine dump sorting and upgrading <br /> operation, approximately 90 percent ,6f the material will have <br /> been removed from its present location. <br /> The 'Wynona mine dump has a total tonnage of approximately <br /> . 10 ,00P—tjons of material. Sampling has shown that at least <br /> )','OOO -inns of this waste dump material can be raised to ore <br /> grr d 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 tailings 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 . The surface area encompassed by the White <br /> Cloud and Wynona mines ' permit boundary totals. 1 . 819 acres . <br /> This acreage includes the land surface associated wXth the <br /> millsite ( see Map E2 ) . <br /> Milling Plan <br /> Millsite <br /> The accompanying guidelines have been followed in designing <br /> the mill to process the ores that will be produced from the <br /> Gold Hill Ventures ' properties : <br /> 1 . The milling operation has been designed to <br /> have the capability of processing the <br /> several types of ores that are found in <br /> the Gold Hill mining district . These ores <br /> will consist of gold-silver tellurides, <br /> and various combinations of gold-silver- <br /> lead-zinc-copper sulfides . _ <br /> 2 . In order to process both telluride and / <br /> sulfide ores , the mill has been designed <br /> as a composite system of gravity and <br /> flotation concentration. <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 /> 1 <br />
