St George Mining Ltd (ASX:SGQ) has commenced diamond drilling at its flagship Mt Alexander nickel-copper sulphide project, designed to grow the resource beneath its feet in Western Australia.
The company is drilling multiple, deeper nickel-copper sulphide targets at the Investigators and West End prospects, which are associated with a number of electromagnetic conductors.
St George says the targets have strong potential, with the company expecting to make further discoveries of nickel-copper sulphides at Mt Alexander in the short term.
Diamond drilling begins
St George chairman John Prineas said the company had an exciting portfolio ready for drilling.
“Our ongoing systematic exploration at the West End and Investigators prospects has produced excellent results this year including a new, deeper discovery at hole MAD199 and a growing number of downhole EM conductors,” he said.
“These results all point to a very large and fertile mineral system at West End and Investigators that has the potential to host a significant volume of mineralisation.
“This area remains underexplored and only lightly drilled, providing an opportunity for further drilling to deliver exciting discoveries to expand the mineralised footprint that we have identified at Mt Alexander.”
Drill program details
Diamond drilling is occurring on a double-shift basis to ensure drilling is carried out 24/7.
The conductors that are being studied include:
- 81,000 Siemens conductor identified from downhole electromagnetic (DHEM) survey;
- 250-metre strike EM conductor identified from DHEM survey; and
- Down-plunge continuity of the high-grade discovery in MAD199 – the first deep find at Mt Alexander – which returned assays of 11.07 metres at 1.58% nickel, 0.71% copper, 1.23 g/t total PGEs from 333.5 metres, including 3.9 metres at 3.98% nickel, 1.8% copper, 3.1 g/t total PGEs from 340.67 metres and including 1.28 metres at 6.54% nickel, 2.96% copper, 3.88 g/t total PGEs from 342.12 metres.
The company’s drilling has continued to hit massive nickel‐copper sulphides - breakthrough success came with MAD199, which delivered the deepest and western-most occurrence of massive sulphides discovered to date – more than 11 metres of high‐grade mineralisation from 333.5 metres downhole.
