St George strikes deeper high-grade nickel at WA project | Ralph-Lauren

Must Read


ASX-listed St George Mining has delivered a “breakthrough” high-grade nickel sulphide drill hit below previously intercepted mineralisation at the 75 per cent-owned Mt Alexander project in Western Australia’s north-Eastern Goldfields. The 11.07m hit grading 1.58 per cent nickel and 0.71 per cent copper included a 1.28m interval going at 6.54 per cent nickel, 2.96 per cent copper and 3.88g/t PGEs from 342.12m depth.

St George says the drill hole confirms the large intrusive mineral system identified on the Cathedrals Belt at Mt Alexander “can host significant high-grade mineralisation at depth”.

Assays are pending for another hole that is said to have picked up 2.4m of nickel-copper sulphides from 434.6m down-hole some 125m down-plunge of its newly reported intercept.

St George says assays for the down-plunge intersection are awaited. The sulphide mineralisation is open in all directions. Intriguingly, three strong electromagnetic conductors interpreted to have a massive sulphide source have been identified from the step-out hole.

The company has been drawing market attention with its drilling at Mt Alexander, with multiple high-grade intercepts reported at the Stricklands, Cathedrals and Investigators prospects over 6.5km of strike along the Cathedrals Belt.

Its newly reported intercept is below shallower mineralisation at Investigators where previous drilling returned numerous eye-catching results including 7.86m at 5.7 per cent nickel, 2.1 per cent copper, 0.18 per cent cobalt and 2.65 g/t PGE from 184m.

Other previous hits at Investigators include 8.49m at 5.8 per cent nickel and 2.6 per cent copper from 183.9m in addition to 8.4m at 2 per cent nickel and 1 per cent copper from 199m.

St George has launched into new geophysical surveys looking to pin-point targets for future resource drilling and testing at depth.

A deep ground-penetrating radar survey will look to generate a 3D model of shallow mineralisation to 150m depth while a seismic survey to produce a high-definition map to 2km depth is also on the cards for July.

Down-hole electromagnetic surveying is planned for a recently completed hole that intercepted intrusive rocks at the largely untested western end of the Cathedrals Belt.

St George is currently looking to secure a diamond rig to resume drilling at Mt Alexander.
