Mine Info
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.

Comments
Comment (Deposit): NBMG SAMPLE #4104 IS GRAB PYRITIZED AND SILICIFIED ANDESITE FROM DUMP. SAMPLE #4105 IS SELECT PYRITIZED, ARGILLIZED AND SILICIFIED ANDESITE FROM DUMP OF SHALLOW CAVED SHAFT 705M NORTH (NO MINERALIZATION STRUCTURE OBSERVED). SAMPLE #4106 IS SELECT SILICIFIED AND LIMONITE ENCRUSTED ANDESITE FROM A N15W HIGH ANGLE FAULT ZONE.
Comment (Geology): THE PROSPECTS ARE LOCATED NEAR A ZONE OF LAG BOULDERS AND OUTCROP OF VERY LIMONITE-RICH (HYDROTHERMALLY ?) BRECCIATED SILICIFIED ANDESITE (ALTA ANDESITE). ENARGITE IS RARE ON THE DUMP; WELL-CRYSTALLIZED PYRITE IS EXTREMELY COMMON. PRESUMABLY THE SILICIFIED ZONE PRESERVED SULFIDES AT SHALLOW DEPTHS FROM SUPERGENE OXIDATION.
Comment (Workings): THREE SMALL DUMPS FROM CAVED ADITS.
Comment (Deposit): RIDGE AND ALTERED ZONE TRENDS E-W.
