St George unveils ‘remarkable’ WA nickel target at depth


Western Australian nickel explorer St George Mining has unveiled a fascinating large nickel-copper sulfide target under its Investigators prospect located on its Mt Alexander project in northeast Goldfields. Previous drilling on the prospect has yielded several shallower interceptions, including an 8.49 meter crack containing 5.8 percent nickel and 2.6 percent copper from 183.9 m. The company now plans to drill test the deeper priority target early next year.

St George has already returned numerous hits of high grade nickel-copper on several prospects along some 5.5 kilometers of the Cathedrals mineralized belt in its territory, including to Investigators.

Investigators’ other previous drilling results include 7.86 m at 5.7% nickel and 2.1% copper at 184 m and 8.40 m at 2.0% nickel and 1.0% copper at 199 m.

The company is looking for more goodies mineralized under high grade mineralization already confirmed by its drilling along the cathedral belt. The first signs seem encouraging with a large priority target discovered in depth.

A recent seismic study – the first ever conducted at the cathedral belt – illuminated the new geophysical target under Investigators which stretches over 450 m.

Oddly enough, the target is interpreted by St George to contain the same geophysical signature as previous seismic work carried out in shallower areas where subsequent drilling hit high grade nickel and copper.

According to St George, there are no other known rocks apart from massive sulphides that could have returned a similar seismic reading in the cathedral belt.

The company believes the location of the new seismic target is consistent with its geological interpretation of the Cathedrals Belt to potentially harbor massive sulphides down-dip of already intercepted nickel-copper mineralization closer to the surface.

The new target is about 800 m deep.

St George Mining Executive Chairman John Prineas said: “We are delighted with the results of the very first seismic survey at Mount Alexander which not only provided a breakthrough in our understanding of the complex Mount Alexander intrusive system, but also an exceptional new target for a potential massive sulphide deposit.

Our systematic exploration over the past year has primarily focused on testing the deeper areas of Mount Alexander to build on the four more than 5 shallow high-grade nickel-copper sulfide discoveries already made, 5 km in length east-west of the belt of cathedrals. . The geological thinking is that if the system is that long, it must also be deeper than the shallow mineralization identified. “

St George is now planning to launch the platform early in the New Year to break through the exciting target lurking beneath investigators.

Oddly enough, the seismic study also detected other interesting structures parallel to the belt of cathedrals, according to the company.

A total of seven structures warranting further investigation have now been mapped by St George. He believes that the intersection of newly identified south-dip structures and north-dip structures could represent a trap site for sulphide mineralization for drilling in the future.

With the price of nickel trading at around US $ 20,000 per tonne – levels not seen since 2012 – and copper flirting with all-time highs above US $ 9,000 per tonne, St George may have some pushes to come. it is happening to something decent under the important mineralized horizon already identified along the belt of the cathedrals.
