Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): NEAR THE HEAD OF A SMALL TRIBUTARY THAT JOINS TELEGRAPH CREEK AT HUB CAMP. ; INFO FROM LAND.ST :(1954)
Comment (Production): USGS BULL 842.
Comment (Deposit): THE VEIN IS INCLOSED WITHIN WELL DEFINED WALLS OF GRANITE. ALONG THE WALLS THERE IS CONSIDERABLE GOUGE DUE TO POST MINERAL MOVEMENT. ON THE 300 FT LEVEL THE VEIN HAS BEEN MINED 300 FT W AND 900 FT E TO AN ANDESITE CONTACT.
Comment (Workings): SHAFT, HAS LEVELS ON THE 200 & 300 FT LEVELS
Comment (Geology): AU DECREASED AND AG INCREASED WITH INCREASING DEPTH WITH LITTLE EVIDENCE OF OXIDATION OR ENRICHMENT. TETRAHEDRITE HAS HIGH AG CONTENT. THE ORE SHOWS DEPOSITION TO HAVE TAKEN PLACE DURING TWO OR MORE PERIODS.
