Great Southern hits the high notes with Amy Clarke’s air drill

Aircore drilling returned shallow gold intersections with a remarkable 8m strike grading 6.7g/t gold at Great Southern’s Amy Clarke prospect in Western Australia.

Importantly for the company, the gold intersections have an excellent correlation with mile-scale gold in the ground and immobile precursor elements, which form a newly defined mineralized trend.

Adding more interest, the high-grade bedrock intersections suggest that the source of the gold anomalies is nearby.

For Great Southern Mining (ASX:GSN), the combination of continuous scale and strike anomalies highlights the potential of the Amy Clarke Prospect within the Duketon Gold Project to host a significant gold deposit at depth.

The soil anomaly is similar in size and grade to Regis Resources’ (ASX:RRL) 2.1 Moz Garden Well gold mine – the largest gold deposit in the Duketon greenstone belt.

“These new shallow air core results are an exciting development for Amy Clarke’s perspective,” said general manager Sean Gregory.

“The geological team has spent the last year advancing this area from a conceptual target to now an area that has high grade gold intersections.

“It also demonstrates that the methodology employed by the exploration team is working to advance our projects towards discovery.”

The Company is currently awaiting downhole multi-element assay results and 1m gold assay data from the mineralized air core intervals to head towards deep drill targets.

Drilling from concept to gold

The 172-hole program totaling 5,586 m was completed in December 2021 to assess the gold potential of kilometric gold in ground anomalies delineated in September last year.

Several holes encountered gold anomalies that form a consistent north-south gold trend across the prospect.

Great Southern notes that the top hit is part of a larger anomaly that has excellent correlation with mile-scale gold in the ground anomaly and is also the first high-grade hit in the Amy area. Clarke with grades consistent with those found in gold deposits throughout the Goldfields region.

The position of the intercept is also encouraging as it is 32-40m downhole in sheared basalt with quartz veins in fresh rock below the altered zone.

Additionally, bismuth in soils showed an excellent correlation with the soil gold anomaly with concentration toward central “hot spots.”

Aircore drilling has confirmed that bismuth is a good indicator of gold mineralization as the main mineralized trend, while the high-grade intersection is directly aligned with the bismuth anomaly.

Other work

In addition to awaiting multi-element, downhole assay results and 1m gold assay data, Great Southern plans to commence a geological mapping exercise on the Amy Clarke/Ogilvies area to investigate anomalous trends and further refine regional target areas.

Exploration at Amy Clarke is still in its early stages, but the high-grade gold intersection is certainly encouraging.

The company is also awaiting assay results from two diamond holes it drilled at Southern Star.

Information from these holes will inform Southern Star’s planned reverse circulation drilling program.
