The 100%-owned North Telfer Project area covers 144 km2 and features a geological structure referred to as Minyari Dome, which hosts the Minyari and WACA deposits. Minyari and WACA contain a combined Mineral Resource of 723,340 ounces of gold, 26,390 tonnes of copper, 233,290 ounces of silver and 4,060 tonnes of cobalt.

The Paterson Province geological setting of the Minyari and WACA deposits is Proterozoic-aged, predominantly meta-sediment hosted hydrothermal shear, fault and strata/contact controlled precious and/or base metal mineralisation. The mineralisation in the region is interpreted to be intrusion-related. Local controls on mineralisation involve variations in both the competency/hardness and chemical composition of rock units, in combination with other “discrete” structural controls.

Drilling during 2018 revealed significant new mineralisation at the Minyari South (strike length 100m and open in all directions) and Judes (strike length 150m and open in all directions) prospects.


 

MINYARI

The mineralisation at Minyari bears a number of similarities to the mineralisation at the Telfer deposit. In particular, variations in both the hardness and chemical composition of rock units, when combined with other structures, give rise to similar styles of mineralisation as that seen at Telfer.

Mineralisation at Minyari starts at 0-10 metres from the surface and extends down more than 580 vertical metres. The mineralised corridor extends over 400 metres in length and up to 60 metres in width and remains open down dip and potentially along strike.

Minyari contains an Indicated and Inferred Mineral Resource of 7.7 million tonnes grading 2.2 g/t gold, 0.3% copper, 0.9 g/t silver and 460ppm cobalt for 550,610 ounces of gold, 22,760 tonnes of copper, 213,520 ounces of silver and 3,540 tonnes of cobalt.

WACA

Like Minyari 700 metres to the south-west, the mineralisation at WACA bears similarities to the Telfer deposit. In particular, variations in both the hardness and chemical composition of rock units, when combined with other structures, give rise to similar styles of mineralisation as that seen at Telfer.

The mineralisation at WACA starts at 0-20 metres from the surface and extends down for more than 340 vertical metres over a strike length of more than 650 metres. Two main lodes occur within a corridor that is up to 50 metres in width. The deposit remains open down dip and potentially along strike.

WACA contains an Inferred Mineral Resource of 3.3 million tonnes at 1.6 g/t gold, 0.11% copper, 0.2 g/t silver and 190ppm cobalt for 172,730 ounces of gold, 3,630 tonnes of copper, 19,770 ounces of silver and 620 tonnes of cobalt.
