Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comment (Commodity): Au: 0.03 - 2.0 oz/ton over 5-ft drill intercepts with 0.01 oz/ton cutoff grade Ag: 1 to 4 oz/ton

Comment (Geology): Small discontinuous bodies of oxidized and primary mineralization in stockwork zones in porphyry associated with intrusion breccias.

Comment (Location): The prospect is centered near the saddle between Farncomb and Humbug Hills, and on Brewery Hill 1 mile to the north, all about 4 miles east of Breckenridge, mostly in secs. 26 and 35, T 6 S, R 77 W.

Comment (Reserve-Resource): Drilled by FMC Gold Corp. in the mid-1980s. Numerous mineralized intercepts reported. Sunshine examined this property in 1988 as a submittal from FMC Gold Corp. Determined to have potential for several small orebodies. Two possibly economic orebodies were identified by FMC drilling, the "WP-9 Zone" and the "Elephant Zone". Estimated combined potential of 100,000 to 200,000 oz of gold. However, property not acquired by Sunshine due to high "political and environmental risks", being close to a resort area.

Comment (Reserve-Resource): Overall average drill-defined widths in stockworks zone of 17.3 ft grading 0.28 oz/ton Au. Mineralization is interpreted to be "spotty" however.
