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
