Satelite View

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

Comments
Comment (Location): ON SOUTH SIDE OF WOLF CREEK 0.2 MILE WEST OF COLORADO RTE 149. ; INFO FROM LAND.ST :1976
Comment (Workings): CDM REPORTS DESCRIBE WORKINGS AS 25-FT-DEEP SHAFT; 20-FT-DEEP SHAFT WITH 10-FT DRIFT DRIVEN EASTWARD FROM BOTTOM; 200-FT-DEEP SHAFT WITH 20-FT DRIFT DRIVEN WESTWARD FROM BOTTOM, 38-FT CROSSCUT DRIVEN NORTHWARD AT DEPTH OF 140 FT IN SHAFT, AND 37-FT CROSSCUT DRIVEN NORTHWARD AT DEPTH OF 50 FT IN SHAFT AND CONNECTING TO 50-FT-DEEP SHAFT SUNK 37 FT NORTH OF 200-FT SHAFT; OPEN CUTS.
Comment (Deposit): NELSON AND RIESMEYER (1983) DESCRIBE DEPOSIT AS AU-BEARING PYRITE-ARSENOPYRITE-MAGNETITE-BEARING CHERT AND AU-BEARING GARNET-CHLORITE-HORNBLENDE-MAGNETITE SCHIST. DEPOSIT IS THOUGHT TO REPRESENT FERRUGINOUS CHEMICAL/CLASTIC SEDIMENT FORMED IN SHALLOW BASIN DEVELOPED IN BASALTIC ROCKS. CHERT LAYER TRENDS ENE-WSW AND LIES ON NORTH LIMB OF CHAMPION SYNFORM, WHICH IS CUT AND DISPLACED BY THREE NW-TRENDING FAULTS. DROBECK (1981) DESCRIBES CHERT LAYER AS LYING NEAR CONTACT BETWEEN METASEDIMENTS ON NORTH AND METAVOLCANICS ON SOUTH AND ASSOCIATED WITH A THINNED PORTION OF KOMATIITE FLOW. NO MASSIVE SULFIDE WAS FOUND IN DEEPLY WEATHERED GARNET- (ALMANDITE-) BEARING BIOTITE SILTSTONE ON STRATIGRAPHIC FOOTWALL. DISSEMINATED PYRITE AND CHALCOPYRITE WERE FOUND IN REMOBILIZED QUARTZ VEINS WITHIN CHERT LAYER. CHERT AND REMOBILIZED QUARTZ CONTAIN ANOMALOUS AU, SE, AND TE.
