Sirius Resources has found a new gossan at its Polar Bear project in Western Australia.

The gossan, known as the Dundas gossan, averages 2.8% copper, 0.8% nickel and 13.3g/t total platinum group metals, including 2.8g/t platinum, 5.6g/t palladium and 1.0g/t rhodium.

It was discovered buried beneath a thin layer of salt lake sediments during geological mapping, located 550m to the south-east of the Halls Knoll gossan where Sirius previously reported outcrop grades averaging 1% copper and 0.75% nickel.

Sirius Resources managing director Mark Bennett said the gossan identification reinforces the company’s belief that this ultramafic rock unit is highly prospective.
