St George Mining Ltd (ASX:SGQ) has confirmed the discovery of nickel-copper sulphide mineralisation through maiden assays from the Stricklands Prospect within the Mt Alexander Project in Western Australia.
Each of the three new drill holes at Stricklands intersected high grade nickel‐copper sulphide mineralisation including 2.78 metres at 1.62% nickel, 2.51% copper, 0.07% cobalt and 1.88 g/t PGEs.
Assays suggest the potential for further high grade massive nickel-copper sulphide mineralisation within the project.
Down hole surveys of drill holes have identified several electromagnetic conductors that warrant immediate testing.
John Prineas, executive chairman, commented: “We are seeing high grades of nickel and copper in multiple intersections across the project area, which highlights the fertility of the large mineral system at the Cathedrals Belt.
"The sulphides are also high in cobalt and PGEs, further enhancing the potential value of this mineralisation.
"We are increasingly confident that our upcoming drill programme will deliver further exploration success".
Drill result details
Assays were received for four drill holes, three from the Stricklands prospect (MAD20, MAD22, MAD23) and one from the Cathedrals prospect.
Drill hole MAD20 intersected 9.3 metres of weak‐moderate disseminated mineralisation from 44.2 metres depth grading into matrix and massive sulphides with 0.93 metres at 2.5% nickel, 0.68% copper, 0.16% cobalt and 1.1 g/t PGEs.
Drill hole MAD22 intersected 7.95 metres of moderate disseminated‐blebby sulphide mineralisation from 41.9 metres grading into stringer and massive sulphides with 2.78 metres at 1.62% nickel,
2.51% copper, 0.07% cobalt and 1.88 g/t PGEs.
Drill hole MAD23 intersected 3.75 metres of moderate blebby‐disseminated sulphides from 53.7 metres grading into matrix sulphides with 1.5 metres at 1.29% nickel, 0.57% copper, 0.06% cobalt and 1.11 g/t PGEs.
Mt Alexander Project
The Mt Alexander Project comprises three granted exploration licences and is located 120 kilometres south‐southwest of the Agnew‐Wiluna belt which hosts numerous world class nickel deposits.
The Cathedrals nickel‐copper discovery as well as the Stricklands and Investigators Prospects are held in joint venture with Western Areas Ltd (ASX:WSA).
St George is the manager and holds a 75% interest with Western Areas retaining a 25% non‐contributing interest until a decision to mine.
Analysis
St George’s discovery of massive nickel-copper sulphides at Stricklands is important in the evolving exploration model at Mt Alexander.
It also confirms that the high grade mineral system in the Cathedrals Belt is much more extensive than previous drilling had indicated.
Furthermore, it has positive implications for the multiple ultramafic belts to the south of the Cathedrals Belt, which remain under-explored.
The discovery of high grade nickel‐copper sulphides at Stricklands suggests the mineralised ultramafics in the Cathedrals Belt extend intermittently for over 3 kilometres.
An upcoming drill programme will be announced next week, with drilling planned to commence late next week.
St George shares are trading up 110% year to date as it continues its dual exploration focus on nickel and gold in Western Australia.
