Subject category Comment text
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.
