The Mount Rankin Project is located only a few kilometres southwest of the township of Southern Cross in the Yilgarn Craton of Western Australia. The project covers an area of 205 square kilometres of highly prospective rocks of the Southern Cross Greenstone Belt.
Outside of the project area the Southern Cross Greenstone Belt has produced over 10 million ounces of gold and contains an estimated further 3 million ounces in resources. Over 2 million ounces of gold have been produced within a twelve kilometre radius of the project.
In addition to the gold potential on the property there are ultramafic units that are highly prospective for nickel sulphide mineralisation, as seen at the Flying Fox deposit located approximately 100km to the south of Gryphon Minerals’ Mt Rankin Project. The Western Areas Ltd Flying Fox deposit has produced some spectacular drill intersections such as 21.4m @ 7.8% Ni, which makes up part of the 79,900 tonnes of contained nickel resource at the Flying Fox deposit. The package of ultramafic rocks in the Forrestania region are interpreted to be the same or similar rocks that extend north onto the Mount Rankin Project area.
The Mount Rankin Project area has had relatively little exploration for gold and virtually no exploration for nickel mineralisation compared to other parts of the Southern Cross Greenstone Belt. This is primarily due to previous explorers focusing their efforts around the +1 million ounce gold producing mines such as Marvel Loch, Copperhead and Yilgarn Star.
Gryphon Minerals has undertaken first pass geological and geophysical mapping and historical reviews that have identified areas for targeting gold and nickel project over the coming year.
