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): DEPOSIT HAS BEEN GIVEN THE INFORMAL NAME OF A BRECCIA PIPE CU DEPOSIT, FOR WHICH THERE IS NO PUBLISHED MODEL. FRACTURE ZONE IN ANDESITE 80-100 FT WIDE IS MINERALIZED IN PLACES AT COPPER GLANCE MINE. ADDITIONALLY, AREA CONTAINS TOURMALINE-BEARING BRECCIA PIPES AND ALTERED ROCK

Comment (Workings): 200 FT ADIT, 50 FT ADIT, AND OPEN CUTS.

Comment (Location): UNSURVEYED. NEAR COPPER GLANCE CREEK ABOUT 0.75 MI WEST OF EIGHTMILE CREEK. MINERALIZED AREA EXTENDS INTO SECS. 23-26 AND 34

Comment (Development): R.E. KUCERA WAS EXPLORING MINERALIZED AREAS OF ANDESITE OF ISABELLA RIDGE IN AND NEAR COPPER GLANCE MINE

Comment (Deposit): 12 UNPATENTED CLAIMS AND A MILLSITE. ; INFO.SRC : 1 PUB LIT

Comment (Geology): MINERALIZATION IS IN SMALL SHEARS IN ANDESITIC TUFFS AND BRECCIAS CUT BY SEVERAL PLAGIOCLASE PORPHYRY DIKES. ANDESITE AND BASALT FLOWS PRESENT LOCALLY, PARTICULARLY IN UPPER PART, AND RHYOLITIC OR DACITIC TUFF AND BRECCIA ARE FOUND LOCALLY IN MAFIC ROCKS. MUDFLOWS ARE ALSO FOUND IN THIS SEQUENCE. THIN LENTICULAR BEDS OF SEDIMENTARY ROCKS ARE INTERLAYERED WITH VOLCANIC ROCKS. THESE FORMED IN AN ISLAND ARC SETTING
