St George hits 8.6% nickel and 2.6% copper in Leonora

ASX listed St George Mining’s Investigators Prospect at the Mt Alexander Project near Leonora in Western Australia is shaping up to be a compelling target for nickel-copper discoveries.

A step-out drill hole drilled in the eastern section of the prospect to test a bullseye electromagnetic target intersected some seriously high grade nickel-copper sulphides with portable XRF readings going up to 8.6% nickel and 2.6% copper. Laboratory assays are pending.

The hole had intersected a prospective ultramafic unit between 102.9m and 116.65m downhole before drilling through massive sulphide mineralisation from 116.65m to 119.55m.

St George said that with only a single line of drilling completed within the 200m east-west strike of the large bullseye anomaly, the target remained underexplored.

Additional drilling will be planned to further test the continuity of the mineralised ultramafic – both along the east-west strike and at depth.

The company added the mineralised ultramafic in this area dips to the north and thickens at depth.

St George will complete a down-hole electromagnetic survey in the new hole later this week to assist in identifying the extent of the massive sulphides around it and the potential for further downdip extensions.

Two other holes completed at Investigators to test separate electromagnetic conductors also intersected sulphide mineralisation indicating that the mineralised ultramafic is still open.

St George Executive Chairman John Prineas said: “ … we are seeing more high-grade mineralisation at depth at Investigators. We are planning drill holes to further test these depth extensions to the north and north-west.”

“With very little drilling here beyond 200m from surface, we believe this is a compelling exploration area for further discoveries at Investigators.”

Last month, a new diamond hole at Investigators intersected 7.55 metres of base metal mineralisation from 199.75m down-hole, including a 1.27m section of massive nickel-copper sulphides from 206.03m that returned exceptional XRF assay readings of 8% nickel and 7% copper.

These results confirmed significant mineralisation over a plunge length of at least 320m and that the ore system is still open to the northwest.

They also verified a further 100m of down-dip continuity for the high-grade mineralisation that returned 5.3 metres grading 4.95% nickel, 2.75% copper, 0.16% cobalt and 4.55g/t total platinum group elements in drilling completed last year.

St George’s current drilling campaign is already starting to show signs of bearing fruit and the next couple of weeks are likely to be an interesting time for St George shareholders.
