• Great Southern Mining reports up to 12.5g/t at Golden Boulder prospect
• Prospect is just one of several promising targets at its 100% owned Duketon gold project
• Region is host to the Regis Resources >5Moz deposit Garden Wall deposit

Special Report: Great Southern Mining has intercepted up to 12.5g/t gold in its ~1950m reverse circulation drilling campaign at the Golden Boulder prospect at its Duketon gold project in WA.

Golden Boulder sits on a prominent north-south structural trend that is host to multiple gold deposits, including Rosemont (>2Moz), Baneygo (~380,000oz) and Ben Hur (~390,000oz).

The area itself has over 50 historical working over a 3km stretch, with historical production (1900 to 1955) recorded at 1915 tonnes at 28.6g/t gold for 1761 ounces of gold.

The company has intercepted shallow high-grade gold in step-out drilling at the prospect.

Notable results include:

• 4 m at 5.64g/t gold from 63 m, including 2m at 9.89g/t gold
• 3m at 4.80g/t gold from 18m, including 1m at 12.45g/t gold; and
• 2m at 3.44g/t gold from 141m.

The program also successfully extended the higher-grade mineralised zone at Golden Boulder by 85m to 370m total and gold anomalism now extends over 2.3 km with very sparse drilling.

A further 1.4 km of prospective strike remains untested to the south.

“Golden Boulder continues to return shallow high-grade intercepts,” Great Southern Mining (ASX:GSN) managing director Matthew Keane said.

“Following several low-metreage targeted drilling programs, we believe this prospect now warrants a significant drill-out to test the 3.7km prospective trend.”

GSN remains confident that exploration to date supports the company’s belief that its tenure could host the next major deposit in the region.

This includes the new Boundary prospect, where the first ever holes intercepted grades up to 2.24g/t gold .

“We are also highly encouraged by the early success at the Boundary prospect,” Keane said.

“We believe this area holds significant potential for gold discoveries given its location along a major structural zone, which lays host to Regis Resources’ +5 Moz Garden Well deposit located 20 km to the north.”

At Southern Star, there’s over 7km of prospective strike with broad intercepts including 59m at 2.1g/t, and at the Amy Clarke prospect, the company has flagged up to 8m at 6.7g/t gold from previous shallow air core drilling.

Given the scale and high prospectivity of targets defined at the project, the company now plans to embark upon a multi-phase drill-out program.

While around 10Moz of gold has been identified in the Duketon region to date, Regis Resources boss Jim Beyer recently said the district had a bag of potential with deposits increasingly extending at depth and only around a decade of intensive modern exploration compared to upwards of 50 years in other established WA gold fields.

It opens the door for both Regis and other explorers in the area like Great Southern to make significant new gold discoveries in an underexplored domain.
