Great Southern Mining Ltd (ASX:GSN) has received multiple broad high-grade gold results from the latest drilling at its Cox’s Find Gold Project near Laverton in Western Australia which the company has described as "outstanding".
While exploration work at Cox’s Find is still at an early stage, this phase of step-out and extensional reverse circulation (RC) drilling has returned strong intersections within a possible larger gold-hosting system.
Hole 20CFRC0015 returned 9 metres at 5 g/t gold from 142 metres within a broader zone of 16 metres at 3.7 g/t from 138 metres while hole 20CFRC0014 returned 2 metres at 14 g/t gold from 146 metres.
The latter sits outside the interpreted main historical mining lode, being the lode known to be the focus of the historical underground mining in the late 1930s while the former is interpreted to be the Cox’s Find main lode.
In-ground results “excellent”
Managing director Mark Major said: “Another great result. We are now seeing high-grade mineralisation outside the historical main mining lode.
“It’s still very early in the exploration process with just over 8,000 metres of drilling processed at Cox’s Find by GSN since acquiring it in 2019.
“The knowledge acquired and the in-ground results have been excellent.
“We are now looking forward to finishing off the RC drilling, completing the diamond core processing and obtaining the assays for the other half of the program to undergo detailed interpretation.”
Great Southern considers this new area to be a ‘significant’ finding and is interpreted as either an extensional 'blow zone' connected to the main mining lode or an additional new high-grade shoot that is commonly found within high-grade systems.
Extensive 9,000-metre program
Currently, the company has only received assays for the first 15 RC drill holes and only one of the five diamond drill holes.
This equates to approximately 3,286 metres of drilling having been assayed from an extensive 9,000-metre program.
Cox’s Find is a shear hosted Archaean orogenic gold deposit in the Duketon Greenstone Belt in the Laverton district of WA, along strike from and within 12 kilometres of Regis Resources Limited’s (ASX:RRL) multi-million-ounce Garden Well.
The mine was operated by Western Mining Corporation (WMC) for a short period between 1937 and 1942, producing approximately 77,000 ounces of gold at a reported head grade of around 22 g/t from a vein stope operation.
"Understanding advancing daily"
Chief operating officer Mark Major said the highly encouraging early results from the deposit demonstrated the prospectively and opportunity at the recently acquired deposit.
He said: “When the company acquired the Cox’s Find deposit last year, we had a very positive view on the potential upside at the project given that it had seen virtually no exploration in the last 30 years and the exploration undertaken had been focused on shallow exposure and undertaken without systematic geological exploration.
“That view has been firmly supported by these early results from a limited program of drilling thus far.
“This is the first time a focused exploration program has looked to test the extensions of a known gold lode from a 1930’s mine development.
"Importantly the recently drilled diamond core drilling was the first diamond core hole program drilled into a gold-bearing mineralised system of the mine.
“Our understanding of the structural controls and lithological associations of this deposit is advancing daily.”
