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 (Workings): MAIN ADIT DRIVEN N 80 E FOR 125 FT, THENCE SOUTH FOR 85 FT TO FACE. OTHER SHORT ADITS TOTAL 275 FT; 10-FT SHAFT; OPEN CUTS; 5-TON FLOTATION PLANT

Comment (Location): (LAND STATUS AND ADMINISTRATIVE AREA LOCATIONS CALCULATED USING GIS OVERLAY ANALYSIS FOR SAN JUAN N. F.). ALONG NORTH FORK WEST MANCOS RIVER IN SLIDEROCK BASIN 0.6 MILE SW OF SHARKSTOOTH PEAK AND 0.9 MILE NE OF HESPERUS MTN, 4.1 MILES NW OF LA PLATA TOWNSITE (UNSURVEYED SECTION). ; INFO FROM LAND.ST :1974

Comment (Geology): EAST-TRENDING FAULT IN MORRISON FORMATION AND PORPHYRY.

Comment (Exploration): NEWMONT DRILLED THIS AREA IN 1988.

Comment (Deposit): COUNTRY ROCKS CONSIST OF SW-DIPPING JURASSIC AND CRETACEOUS SEDIMENTARY ROCKS INTRUDED BY DIORITE-MONZONITE PORPHYRY DIKE AND SILLS. GENERALLY EAST-WEST-TRENDING FAULT DISPLACES MORRISON FM AND DAKOTA SANDSTONE ON NORTH AGAINST MORRISON FM ON SOUTH. PORPHYRY DIKE FOLLOWS FAULT ALONG SOUTH WALL. FAULT MARKED BY 5- TO 10-FT ZONE OF STRONGLY BRECCIATED, PARTLY SILICIFIED ROCK WITH QUARTZ-PYRITE VEINLETS. FOR AT LEAST 40 FT ON EACH SIDE OF FAULT, ROCKS ARE WEAKLY SHEARED AND CONTAIN SCATTERED STREAKS AND VEINLETS OF PYRITE AND OF QUARTZ INTERGROWN WITH PYRITE AND ARSENOPYRITE. DEPOSIT IS OF INTEREST IN THAT ORE IS LOCALIZED ALONG STRONG FAULT THAT CHARACTERIZES NW PART OF DISTRICT.
