St George identifies new nickel target at Windsor

THE DRILL SERGEANT: St George Mining (ASX: SGQ) has identified a new EM conductor at the Windsor nickel sulphide prospect within the company’s 100 per cent-owned East Laverton property in Western Australia.

The conductor was identified by a downhole electromagnetic (DHEM) survey recently completed at the Windsor prospect , which surveyed drill hole WINRC005.

St George said this has identified an off-hole EM response situated proximally to a zone of disseminated nickel sulphides the company has intersected in three previous RC (reverse circulation) drill holes at the Windsor prospect.

Newexco, the company’s geophysical adviser, has designed a drill hole to test this EM conductor.

St George explained disseminated nickel sulphides do not provide an EM response, which it has led it to consider a potential source for this EM conductor is matrix or massive sulphides.

WINRC005 intersected a thick inner section of a komatiite channel between 127 metres to 269 metres, with an average nickel value over this section of 0.31 per cent nickel (based on interim XRF results).

Higher grade zones in WINRC005 included:

1m at 0.53 per cent nickel from 155m; and

5m at 0.44 per cent nickel from 162m.

“A combination of drilling and downhole EM surveys has resulted in many major nickel discoveries in the Yilgarn in recent years,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“We are applying this approach in our current drilling program and the results so far are very, very encouraging.”
