Growth-focused Western Australian nickel company St George Mining (ASX: SGQ) has intersected massive nickel-copper sulphides from diamond drill hole MAD209 – the first drill hole of the extension and infill drill program underway at its Mt Alexander nickel-copper sulphide project, located in WA’s northern Goldfields.
MAD209, which was scheduled to test an EM conductor (9,825 Siemens), intersected 5.2m of nickel-copper sulphide mineralisation from 112.9m downhole and has confirmed the continuity of mineralisation approximately 35m to the north-west of the existing mineralised envelope for the Stricklands deposit.
The success of MAD209 is an encouraging start to the extension and infill drill program that St George believes will deliver a significant expansion of the known near-surface, high-grade nickel-copper-PGE mineralisation along the Cathedrals Belt.
The company said that all four shallow, high-grade discoveries within the Cathedrals Belt – Stricklands, Cathedrals, Investigators and Radar – remain open and have the potential for additional high-grade nickel-copper-PGE mineralisation which it will explore through further drilling.
John Prineas, St George Mining’s Executive Chairman, said: “Our exploration strategy at Mt Alexander has a dual-track approach. Firstly, we aim to increase the known areas of shallow, high-grade nickel-copper sulphides. Secondly, we will test several large, high-priority conceptual targets areas that have potential for a new discovery.
“The shallow deposits along the Cathedrals Belt are open and further drilling offers an excellent opportunity to add more tonnes to a potential mining inventory at a low cost. All metallurgical testwork completed on these ore bodies has confirmed the ability to produce separate nickel and copper concentrates at high-grades and quality that will be attractive to end-users.
“This underscores St George’s strategy to expand the mineralised envelope for these deposits as we continue to assess potential development scenarios. “We are also excited by the second limb of our exploration strategy – to test the new targets that could deliver a large-scale discovery at the Project as we announced in our ASX release on 29 March 2022.
“The shallow, high-grade discoveries already made in the Cathedrals Belt are proof of a fertile, high-grade mineral system. The extensive strike of the discoveries – over more than 5km along the Cathedrals Belt – supports the case for further significant mineralisation to be present at depth or along strike.
“We are determined to create substantial shareholder value through these compelling opportunities at the high-grade Mt Alexander Project.”
