Growth focused Western Australian nickel company St George Mining (ASX: SGQ) today announced further strong drill results at its flagship Mt Alexander nickel-copper sulphide project, located in the north-eastern Goldfields of WA.
HIGHLIGHTS:
-
Multiple intersections of mineralised mafic-ultramafic units across a 4km-long east-west strike of the Cathedrals Belt with a target horizon open to the east and west.
-
MAD185 at Investigators:
-
25.4m thick mafic-ultramafic intersected from 300.6m downhole.
-
Includes a 15m thick ultramafic with disseminated and blebby nickel-copper sulphides (<5% sulphides with pentlandite (pn), chalcopyrite (cp) and pyrrhotite (py)) from 311.3m downhole.
-
-
MAD184 at Investigators:
-
23.2m thick mafic-ultramafic intersected from 444.5m downhole.
-
Includes a 5m thick ultramafic with disseminated and blebby nickel-copper sulphides (<5% sulphides with pn, cp and py) from 462.7m downhole.
-
-
MAD186 at Cathedrals:
-
57.9m thick mafic-ultramafic from 282.1m downhole.
-
Includes a 2.1m thick ultramafic with disseminated and blebby nickel-copper sulphides (<5% sulphides with pn, cp and py) from 337.9m.

-
Outstanding potential for the discovery of further nickel-copper sulphide deposits along strike to the east and west of these drill holes as well as up-dip and down-dip of the mineralised intercepts.
MORE INTERCEPTS OF MINERALISED MAFIC-ULTRAMAFIC INTRUSIVES
The latest drill holes completed at Mt Alexander continue to intersect mineralised mafic-ultramafic units across an east-west strike of the Cathedrals Belt that extends for more than 4km.
The mafic-ultramafic units are intrusive-style rocks that are known to host high-grade massive nickel-copper sulphides at shallow depths along the Cathedrals Belt.
The identification of further thick intrusive-style rocks with nickel-copper sulphide mineralisation at depth is strongly supportive of the potential for additional massive sulphide deposits to be present within the extensive Cathedrals Belt intrusive mineral system.
Drilling and down-hole electromagnetic (DHEM) surveys are continuing to test for further high-grade nickel-copper sulphide mineralisation along the Cathedrals Belt – both up-dip and down-dip from the mineralisation intersected in the latest drill holes and also along strike to the east and west of those holes.
John Prineas, St George Mining’s Executive Chairman, said: “These results demonstrate continuity of the mineralised mafic-ultramafic units across the Cathedrals Belt over a very extensive strike length.
“This is further evidence of the large intrusive complex at the Cathedrals Belt and increases the prospectivity for significant nickel-copper sulphide deposits down-plunge of the known shallow massive sulphide deposits.
“We are encouraged and excited by the geological potential at the Cathedrals Belt that continues to grow as results from our methodical exploration come in.”
