Special Report: Only a week ago, Great Southern Mining reported it had uncovered shallow high-grade gold at Cox’s Find, now the company has not only extended the main high-grade zone, but it looks as if it’s the highest-grade deposit along strike.

A total of 17 reverse circulation (RC) holes have now been drilled beneath Great Southern’s (ASX:GSN) 100 per cent-owned Cox’s Find pit and confirm high-grade mineralisation extending from the historic underground workings.

These workings previously produced ~76,000 ounces of gold at an average grade of 22.6 grams per tonne (g/t) between 1936 and 1942.

Now, results from a further five holes have delivered bonanza grades of up to 143g/t.

There’s no actual definition of ‘bonanza’ by the way – it’s just a way to describe gold grades.

This 1m intercept came from a broader hit of 5m at 31.23g/t gold from 134m.

Other notable hits returned were 5m at 14.54g/t gold from 140m, including 2m at 28.85g/t from 140m; and 8m at 6.61g/t gold from 128m, including 2m at 19.92g/t from 134m.

To put that in perspective, anything over 5g/t is generally accepted as high-grade – and Great Southern is definitely punching above its weight in that respect.

Earlier results delivered high-grade intercepts of up to 68g/t gold, with drill depths starting at just 74m.

“The maiden RC drilling program has confirmed the extension of the main high-grade lode structure at Cox’s Find and that there is significant remnant mineralisation left,” chairman John Terpu said.

“It’s early days and we still await further results of the drilling program, however, the current results demonstrate that the Cox’s Find gold project is one of the highest, if not the highest, grading deposits along the immediate strike.

“The results to date show good grade continuity with mineralisation open in all directions and provides a solid foundation for the extensional drill program planned for early 2020.”

Great Southern says the high-grade intersections are consistent with, and provide continuity with, the width and grade reported from the development of the underground workings by original owner WMC during operation, which ceased in 1942.

Terpu told Stockhead previously that Great Southern would demonstrate that the mineralisation was open in every direction.

The company continues to prove that, with these new high-grade intersections confirming significant remnant mineralisation remains in the mining area, mineralisation that remains open down plunge and along strike.

And Great Southern has yet to find the edges of this potentially large system.

“We believe this is a stacked reef system,” Terpu said. “There could be two or three underneath the old workings.”
