Skarn Deposits and Location

TSX-V: COCO

Kingfisher Mt Pits ~1966

Skarn deposits are hardly ever simple or from just one event and come in many types mostly sorted by metal endowment.

Gold Skarn deposit selective characteristics

Empire

Mine

Property

• There is no correlation between Cu and Au in many Au skarns thus, the gold potential of a skarn can be easily overlooked if copper sulphide-rich outcrops are preferentially sampled and other sulphide-bearing or sulphide-lean assemblages ignored.
• In some Au skarns there is a metal and mineralogical zoning throughout the exoskarn envelope. This zoning consists of proximal garnet-dominant skarn with high Cu/Au ratios and distal pyroxene-dominant skarn with low Cu/Au ratios and the gold ore bodies.
• Individual deposits can have unique features, In exploration, any skarn of any class should be routinely and systematically assayed for gold. Essentially, any calcareous or carbonate rock package intruded by an arc pluton has a potential for hosting Au skarn deposits.
