Minyari Dome Project

Projects

The 100%-owned Minyari Dome Project area covers 144 km2 and features a geological structure referred to as Minyari Dome, which hosts the Minyari and WACA deposits. In May 2022, an updated Minyari-WACA Mineral Resource was announced. The Minyari-WACA Resource now contains a combined Mineral Resource of 1.8 million ounces of gold, 64,300 tonnes of copper, 584,000 ounces of silver and 11,100 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.

At Minyari during 2021 mineralisation was discovered immediately east, west, and both up plunge to the southeast and down plunge to the northwest, including significant high‐grade breccia style mineralisation.

Minyari

Minyari high‐grade mineralisation is commonly associated with sulphide matrixed breccia zones similar to the Havieron gold‐copper style of mineralisation, with Minyari drilling at depth confirming continuity of moderate northwest plunging “pipe” like high‐grade breccia mineralisation.

Mineralisation at Minyari starts at 0-10 metres from the surface and extends down more than 670 vertical metres. The mineralised corridor extends over 500 metres in length and up to 300 metres in width and remains open in several directions including down plunge providing material resource extension upside.

Minyari contains an Indicated and Inferred Mineral Resource of 28.3 million tonnes grading 1.7 g/t gold, 0.2% copper, 0.6 g/t silver and 0.03% cobalt for 1.5 million ounces of gold, 56,300 tonnes of copper, 537,000 ounces of silver and 9,610 tonnes of cobalt.

WACA

Like Minyari 700 metres to the south-west, the mineralisation at WACA bears similarities to the Havieron gold‐copper 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 and Havieron.

The mineralisation at WACA starts at 0-20 metres from the surface and extends down for more than 510 vertical metres over a strike length of more than 650 metres and up to 100 metres in width. The deposit remains open in several directions providing resource extension upside.

WACA contains an Inferred Mineral Resource of 4.9 million tonnes at 1.2 g/t gold, 0.11% copper, 0.2 g/t silver and 0.02% cobalt for 192,000 ounces of gold, 5,600 tonnes of copper, 27,500 ounces of silver and 1,170 tonnes of cobalt.
