The Quartz Mountain Gold Deposit is a mercury and gold mine located in Lake county, Oregon at an elevation of 5,699 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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): LOCATION GIVEN IS MINE SYMBOL ON 15-MINUTE QUADRANGLE. RECORD INCLUDES CRONE HILL AND QUARTZ BUTTE GOLD DEPOSITS
Comment (Commodity): ORE MINERALS OCCUR IN VEINS, VEINLETS, VEINLET SWARMS, AND BRECCIAS
Comment (Deposit): THIS IS THE LARGEST KNOWN GOLD DEPOSIT IN OREGON. MERCURY DEPOSITS ARE SUPERJACENT TO GOLD MINERALIZATION. TOTAL SULFIDE AVERAGES 3% AT QUARTZ BUTTE AND 8% AT CRONE HILL. HIGH-GRADE VEINS UNDERLIE DISSEMINATED MINERALIZATION. ORE-FORMING SYSTEMS WERE PART OF LATE-STAGE MAGMA EVOLUTION AND MOVEMENT IN THE DOME COMPLEXES.
Comment (Workings): EXTENSIVE DRILLING
Comment (Geology): DEPOSIT IS LOCATED IN A BELT OF RHYOLITE DOMES AND DOME COMPLEXES IN A TERTIARY BIMODAL VOLCANIC TERRANE. OXIDATION IS PRESENT TO DEPTHS OF 165-360 FT. MOST OF THE GOLD IS FOUND IN THE ILLITE-BEARING, ARGILLIC ALTERED AREAS
