Emerging WA nickel stock St George Mining’s (ASX: SGQ) has delivered significant exploration results at its Mt Alexander project near Leonora, with the mineralised ultramafic at the Investigators Prospect found to have an east-west strike of 1.5km and dipping to the north at an angle of about 30 degrees. The company’s geological model supports the potential for continuity of high-grade mineralisation at depth in the northerly down dip direction. Current exploration at Investigators is successfully testing this model.
HIGHLIGHTS
Exploration along the 1.5km east-west strike of the Investigators Prospect confirms that the large mineral system continues at depth with additional massive nickel-copper sulphides as well as new electromagnetic (EM) targets identified in the northerly down dip direction:
-
MAD112 Line:
-
Assays confirm a high-grade intersection in MAD112 that returned: 3.55m @ 4.67%Ni, 2.27%Cu, 0.20%Co and 2.94g/t total PGEs from 116m
-
MAD112 high-grade mineralisation is part of the 120m plunge on the north-south MAD112 Line which remains open to the north
-
Downhole EM (DHEM) surveys in drill holes MAD112 and MAD117 identify a strong offhole conductor (12,700 Siemens) down plunge of the known high-grade nickel-copper sulphides indicating potential for a further extension in the down dip direction
-
-
MAD60 Line:
-
DHEM survey in drill hole MAD119 – a deep step out hole to the north on the northsouth MAD60 Line – has identified a strong off-hole conductor (30,000 Siemens) located down plunge from known high-grade nickel-copper sulphides
-
The new conductor, MAD119:X1, is interpreted to be a continuation of the massive nickel-copper sulphides intersected in MAD108
-
Potential for an extended 380m northerly plunge of mineralisation on the MAD60 Line
-
-
MAD111 Line:
-
Drilling of very strong EM conductors on the north-south MAD111 Line is underway
-
DHEM survey in drill hole MAD121 – a deep step out hole to the north on the MAD111 Line – has identified a weak, very large anomalous EM response (modelled as 400m x 350m) located down plunge from the very strong conductors
-
The new target, MAD121:X1, is interpreted to represent a continuation of the large mineral system at depth and will be prioritised for drilling in the current campaign

Emerging Western Australian nickel company St George Mining Limited (ASX: SGQ) (“St George” or “the Company”) is pleased to provide an update on significant exploration results at the Mt Alexander Project, located near Leonora in the north-eastern Goldfields.
The mineralised ultramafic at the Investigators Prospect has an east-west strike of 1.5km and dips to the north at an angle of about 30 degrees. Our geological model supports the potential for continuity of highgrade mineralisation at depth in the northerly down dip direction.
Current exploration at Investigators is successfully testing this model, providing confidence that the large mineral system continues at depth with potential for significant increases to the known high-grade mineralisation.
John Prineas, St George Mining’s Executive Chairman, said:
“Our methodical exploration strategy at Investigators, using drilling and DHEM surveys concurrently to identify potential extensions of massive nickel-copper sulphides, is delivering excellent results.
“The DHEM surveys at Investigators have been successful in identifying further conductors down plunge from known high-grade mineralisation. This is a textbook fit to our geological model, which envisages potential for additional significant nickel-copper sulphides at depth in the down dip direction.
“The results of the DHEM survey in MAD119 are particularly exciting with potential for the new conductor to extend the plunge of mineralisation on the MAD60 Line to a very significant 380m.
“The east-west strike of mineralisation at Investigators is more than 1.5km, suggesting that any extension of mineralisation to the north will substantially increase the volume of high-grade mineralisation at Investigators.”
