Great Southern has confirmed an intriguing large electromagnetic bedrock conductor at its East Laverton nickel project and it’s ripe for drill testing.

Here’s why the company believes the 2km by 1km sub-vertical conductor at a depth of about 360m is so exciting.

Great Southern Mining (ASX:GSN) executive chairman John Terpu noted the geology of the project area has the potential to host Nova-Bollinger style deposits that typically produce large electromagnetic conductors.

The same kind of conductor that the company has just found on or near the edge of the interpreted Diorite Hill Magmatic Intrusion, which further improves its potential to host nickel sulphide mineralisation.

“We will be drill testing the large conductor as well as another more discrete conductor positioned in the middle of the intrusion as soon as all the approvals are in place,” Terpu added.

“We are also planning further EM surveys along what is referred to as the Rotorua complex, which is a fertile ultramafic that is yet to have any effective drill testing.

“The East Laverton Nickel Project is progressing well and is part of GSN’s strategy to look at all opportunities to create shareholder value through discoveries.”


Re-evaluating historical work and drill plans

The newly identified conductor has led the company to re-evaluate historical work and the position of the basal contact is now interpreted on the south-west margin of the intrusion.

This contact will be targeted for nickel-copper accumulations of the same style as the Nova-Bollinger and Voisey Bay Nickel deposits.

Great Southern plans to drill a 600m hole to test the interpreted bedrock conductor.

Virtually no historical nickel-copper exploration has been carried out over the complex in general and no drilling has taken place at the location of the conductor.

The fixed-loop EM survey also identified a smaller but significantly isolated anomaly L124, located proximal to a magnetic source within the interpreted intrusive.

This has been modelled and will be tested by a 500m reverse circulation drill program.

A review of East Laverton and the adjoining Rotorua complex is currently underway by highly experienced nickel consultant Dr Jon Hronsky, who is looking for nickel and platinum group element potential.
