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.

Land Status

Land ownership: Private
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Deposit): 2 MAIN "LEDGES" CONTAINING PAY SHOOTS; BOUNDED IN PLACES BY A FAULT-GOUGE ZONE. RICHEST SHOOTS FORMED VERTICAL PIPES OR "CHIMNEYS. ORE SHOOTS WERE ERRATIC IN DISTRIBUTION, AND INCLUDED BOTH OXIDE AND SULFIDE ORES. ORE ZONES FOUND IN SILICIFIED PORTIONS NO ORE IN MARGINAL ARGILLIZED AREAS. ORE ZONE BOUNDARIES WERE GRADATIONAL OVER SEVERAL FEET, RICHEST ORE FOUND BETWEEN 180 FT AND 230-FT LEVELS.

Comment (Workings): VERTICAL SHAFT WITH LEVELS AT 80,130,180,230,280, AND 380 FT., IN 1908, LARGE STOPES, SOME OPEN TO SURFACE AS GLORY HOLES.

Comment (Geology): ORE IS IN DACITE ON 80-AND 130-FT LEVELS; IN LATITE BELOW THE 180-FT LEVEL

Comment (Deposit): IN 1966, DAVID-GOLDFIELD MINING CO MADE 2 DEEP EXPLORATORY CUTS JUST EAST OF THE COMBINATION AND JANUARY SHAFTS ; INFO.SRC : 1 PUB LIT

Comment (Development): THE COMBINATION GROUP WAS BONDED TO L.L. PATRICK IN SEPT., 1903. ORE SHIPMENTS BEGAN IN NOV., 1903.-WAS ONE OF THE 4 MAJOR PRODUCERS IN GOLDFIELD FROM 1904-1906. ON MARCH 1, 1907, COMBINATION MINE WAS SOLD TO GOLDFIELD CONSOLIDATED MINES CO. (GEORGE WINGFIELD AND SEN. NIXON.) 175 ACRE CLAIM GROUP. A 10-STAMP MILL WAS COMPLTED IN MAY, 1905, AND ENLARGED TO 20 STAMPS IN LATE 1905.
