Satelite View

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

Comments
Comment (Development): A GRAB SAMPLE FROM A STOCKPILE ASSAYED 6.21% SB, 4 OZ. AG, TR AU.
Comment (Deposit): FORMATION IS CUT BY AN INTERMEDIATE-COMPOSITION DIKE. STIBNITE OCCURS AS SMALL PODS, BLEBS & CRYSTALS SCATTERED RANDOMLY THROUGH THE DIKE AND IN QUARTZ ALONG THE FAULT
Comment (Workings): 41-FT. INCLINED SHAFT, 46-FT. ADIT
Comment (Deposit): DEVELOPED BY 41-FOOT INCLINED SHAFT AND A 46-FOOT ADIT. AT THE ADITS, LIMESTONE AND SHALE OF THE HAMMOND CANYON FORMATION (STRIKING N45E AND DIPPING 20SE) IS CUT BY A SILICIFIED DIKE OF INTERMEDIATE COMPOSITION. A FAULT, STRIKING N45E AND DIPPING 50NW FORMS THE FOOTWALL OF THE DIKE, STIBNITE OCCURS AS SMALL PODS, BLEBS, AND CRYSTALS SCATTERED RANDOMLY THROUGH THE DIKE AND IN QUARTZ ALONG THE FAULT. WHITE ANTIMONY OXIDES AND YELLOW ANTIMONY OXIDES ARE PRESENT. (LAWRENCE, P. 51-52.) ; INFO.SRC : 1 PUB LIT
