Deposit of massive sulfides (Kuroko type) in a metamorphosed island arc complex deformed during the Penokean Orogeny about 1.8 billion years ago. Known only from geophysical and drill core data, this deposit is estimated to contain 0.7 million tons of ore averaging 2.5% copper and 5.2% zinc with significant silver values and minor gold.
