Growth-focused Western Australian nickel company St George Mining (ASX: SGQ) says laboratory assays have confirmed the latest high-grade nickel-copper sulphide discovery at its flagship high-grade Mt Alexander Project in the north-eastern Goldfields.
The assays from drill hole MAD199 confirmed a thick interval of high-grade nickel-copper sulphides that included:
- 11.07m @ 1.58% Ni, 0.71% Cu, 1.23g/t total PGEs from 333.5mincluding
- 3.9m @ 3.98% Ni, 1.8% Cu, 3.1g/t total PGEs from 340.67mand including
- 1.28m @ 6.54% Ni, 2.96% Cu, 3.88g/t total PGEs from 342.12m
Importantly, as the deepest massive nickel-copper sulphides identified in the Cathedrals Belt, MAD199 confirms that the large intrusive mineral system across Mt Alexander can host significant high-grade mineralisation at depth.
The discovery made by hole MAD199 is below the shallow deposits already discovered at Investigators and is the latest high-grade nickel sulphide find at Mt Alexander, where St George continues to grow its footprint of this critical battery mineral.
John Prineas, St George Mining’s Executive Chairman, commented:
“The high-grade intersection in MAD199 is a very important breakthrough in our exploration of the Cathedrals Belt.
“The MAD199 discovery is the deepest occurrence of massive nickel-copper sulphides identified in the Cathedrals Belt and supports the prospectivity of more high-grade deposits at depth.
“With multiple strong EM conductors identified from MAD199 as well as from the first step-out hole at MAD201, we are confident of drilling more high-grade mineralisation in this area.
“The search for nickel-copper sulphides at depth is still at an early stage and we are pleased to be rolling out a low-cost seismic survey that has the potential to identify in high resolution the intrusive host system and any mineral deposits at depth.
“These results and our ongoing work are very positive for the growth potential of the high-grade mineralisation at Mt Alexander.”
