St George Mining has launched into another round of diamond drilling on the hunt to find deeper targets identified by compelling electromagnetic survey results at their 100 per cent owned Mount Alexander Nickel-Copper project in the north-eastern goldfields. The company is also targeting down plunge continuity following an enticing 11.07 metre drill hit grading 1.58 per cent nickel and 0.71 per cent copper from 333.5 metres.
Electromagnetic conductor analysis has identified some interesting targets at the Investigators and West End prospects within the Mount Alexander project. Located 120 kilometres south-southwest of the Agnew-Wiluna Belt, the project hosts numerous world-class nickel deposits.
Modern exploration techniques have rebirthed many previously abandoned prospects and electromagnetic surveys have proved particularly efficient tool for finding massive sulphides. The surveys can test the conductivity contrasts that distinguish between nickel-copper sulphide deposits and the surrounding country rock.
St George identified a solid 250m strike length from a downhole electromagnetic survey that lit up with a whopping 81,000 Siemens conductor reading. The exceptionally high reading has distinguished a target that could potentially indicate the presence of a mineralised nickel-copper deposit.
The current diamond drill program will target the electromagnetic anomaly identified as well as testing the down plunge continuity of a high-grade discovery made at depth earlier in the year at Mount Alexander. The drill holes are designed to test continuity of mineralisation beyond the reach of downhole electromagnetic surveys. If the down plunge extension drilling hits paydirt, the mineralised envelope could be extended by approximately 100m to the west.
The first drill hole will step out approximately 80m east of the 11.07m drill intersection grading 1.58 per cent nickel and 0.71 per cent copper from 333.5m. It is also nearby an exciting drillhole that returned a 3.21m intercept running 1.35 per cent nickel, 0.8 per cent copper and 998 parts per billion platinum group elements.
The second drillhole will home in on the very strong 81,000 Siemens off hole conductor reading associated with a large gravity anomaly, interpreted to be an area of massive sulphide accumulation according to St George.
The third drillhole will target a 250m strike off hole conductor identified by down hole electromagnetic surveys where disseminated nickel-copper sulphides were intersected.
The target of the fourth drill hole will be the down plunge continuity of the 11.07m nickel-copper intersection previously reported.
St George Mining’s Executive Chairman, John Prineas, 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 Mount Alexander”.
Drilling is running around the clock with drill crews double-shifting to ensure the results flow back to the company in a timely manner. With strong targets in every direction they look, St George Mining is well placed to advance its exploration model as the rotary truth diviner zeroes in on potentially more massive nickel-copper sulphides.
