St George Mining (ASX: SGQ) has extended nickel, copper, cobalt and platinum group element mineralisation at its Cathedrals prospect, part of the company’s Mt Alexander project, which is 120km south of a known nickel region in Western Australia.
Latest assays from the November drilling program which tested mineralisation along strike and downhole at Cathedrals revealed a 3.28m intersection grading 5.77% nickel, 2.43% copper, 0.18% cobalt and 5.05 grams per tonne platinum group elements, including a 1.9m interval grading3.45% copper, 0.23% cobalt and 5.61g/t platinum group elements.
Another better intersection was 5.94m at 1.76% nickel, 0.85% copper, 0.06% cobalt and 3.09g/t platinum group elements, including 2.04m interval comprising 2.70% nickel, 1.53% copper, 0.08% cobalt and 3.09g/t platinum group elements.
“The mineralisation at the Cathedrals prospect continues to impress with high grades and shallow depths,” St George executive chairman John Prineas said.
Previous exploration at Cathedrals identified a 7.5m intersection comprising 3.90% nickel, 1.74% copper, 0.12% cobalt and 3.3g/t platinum group elements, including a 3.15m interval grading 6.36% nickel, 2.92% copper, 0.20% cobalt and 5.03g/t platinum group elements.
The assays from Cathedrals are similar to those found at the nearby Stricklands prospect, which is also part of Mt Alexander.
In mid-December St George reported drilling at Stricklands had returned a 17.45m intersection grading 3.01% nickel, 1.31% copper, 0.13% cobalt and 1.68g/t platinum group elements.
St George has carried out preliminary testwork on the ore and managed to produce a high value concentrate containing 18% nickel and 32% copper. Additional concentrates with platinum group elements, gold and cobalt were also produced.
The Mt Alexander project comprises four exploration licences, with both Cathedrals and Stricklands situated on an exploration licence which is held under a joint venture between St George (75%) and Western Areas (25%).
St George is the project manager and Western Areas’ interest in non-contributing.
