Paterson Proterozoic Orogen, Western Australia. Exploration Licence, 240 sq km, granted 2020, 50km from Havieron and 80km from Newcrest’s major Telfer gold mine, of 32M ounces. Adjacent to tenements held by the main players Rio Tinto and by Antipa Resources.
The district has seen a pegging rush, so prospective ground available for sale is rare.
Winu is a major new find announced by Rio Tinto.
In the last few months Greatland Gold plc, and farm-in partner Newcrest, have reported spectacular follow-up drill results in the Havieron prospect (discovered by Newcrest some years ago). These include:
- 121m at 2.93 g/t gold and 0.23% copper from 497m down hole in HAD001;
- 275m at 4.77g/t gold and 0.61% copper from 459m down hole in HAD005
The Havieron mineralisation consists of pyrrhotite-chalcopyrite-pyrite in a Proterozoic brecciated limestone and silty limestone, lying beneath 400m of Permian clastic rocks. There is a coincident magnetic and gravity high which guide exploration.
Exploration Licence 45/5392, 75 blocks, 240 sq km, granted February 2020
Telfer and other deposits in the region are temporally, structurally and possibly genetically related to a suite of granites, many outcropping (or thinly covered), but others sub-surface.
Prospective Proterozoic rocks will, like Havieron, be under cover at about 400m below surface, but MMI has been used successfully in this region to locate buried mineralisation even at these depths.
