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 (Location): UTM IS TO NEAR CENTER OF OPEN PIT AREA. THIS IS THE PROPERTY BEING MINED IN 1990 BY OPEN PIT BY THE AURORA PARTNERSHIP (MINEREX AND ELECTRA NORTHWEST) ON THE HUMBOLDT VEIN. DO NOT CONFUSE THIS DEVELOPMENT WITH MINING SINCE 1987 BY NEVADA GOLDFIELDS ON THE NEARBY PROSPECTUS VEIN, ALSO KNOWN AS THE AURORA MINE. . INFO FROM LAND.ST :1972

Comment (Deposit): A MINERALIZED ZONE ON THE HUMBOLDT VEIN; PROSPECTUS VEIN, JUNIATA VEINS; ALL NE-TRENDING VEINS.

Comment (Workings): OPEN PIT MINE IN AREA OF OLD HUMBOLDT SHAFT. MILL EXPANSION FROM 275 TPD TO 385 TPD.

Comment (Development): LISTED AS AN ACTIVE OPEN PIT MINE AND HEAP LEACH OPERATION IN 1983, EMPLOYING 16 PERSONS. IN 1982, ELECTRA NORTHWEST RESOURCES COMBINED WITH PACIFIC NORTHWEST TO FORM ELECTRA NORTHWEST RESOURCES, LTD. TO DEVELOP ITS PROPERTY, THE AURORA MINE, OVER 200 CLAIMS.IT WAS CONDUCTING DRILLING AND ENGINEERING PROGRAMS AT THAT TIME. PLANS WERE THEN BEING MADE FOR PROCESSING AN INITIAL 30000 TONS. ELECTRA HAD BEEN EXPLORING THE PROPERTY SINCE 1980 OR EARLIER. ELECTRA NORTHWEST FORMED A JOINT VENTURE WITH CENTENNIAL MINERALS, AND BEGAN PRODUCTION IN JULY 1983 AT 1000-1500 TPD. INITIAL RECOVERIES AVERAGED 0.08 OZ/T AU FROM MATERIAL GRADING 0.12 OZ/TON AU. FULL SCALE PRODUCTION WAS PLANNED FOR 1984. MINE LIFE PROJECTED AT LEAST 5 YEARS. ELECTRA RESOURCES WAS DRILLING THE PROPERTY IN 1980-1981, THEN MERGED WITH PACIFIC NORTHWEST TO FORM ELECTRA NORTHWEST RES. LTD. NEVADA COLDFIELDS OPENED AND ADJACENT AURORA MINE AND IN 1987, EXPECTED TO PRODUCE 100--- OZ AU AND 150000 OZ AG IN ITS 5 YR PROJECTED

Comment (Development): LIFE.
