• Great Southern Mining to restart drilling at Duketon gold project in Western Australia
• Company will focus on historic Golden Boulder prospect, among others
• GSN says project is primed for a ‘significant gold discovery’

Special Report: Great Southern Mining plans to recommence drilling at its Duketon gold project in Western Australia next month.
This drilling program will target the Golden Boulder prospect, among others, which has over 50 historical working over a 3km stretch, with historical production recorded at 1,915 tonnes at 28.6 g/t gold for 1,761oz of gold
Importantly, historic drilling at Golden Boulder is sparse and shallow, with very few holes penetrating beyond 40m depth.
Previous drilling at the prospect from the 2021 and 2023 programs included intercepts of:

• 5m at 3.3 g/t gold from 49m, including 1m at 12 g/t (21GBRC0001)
• 5m at 1.2 g/t from 1.3m, including 1m at 4.1g/t (21GBRC0007)
• 8m at 3.9 g/t from 44m, including 4m at 6.8 g/t (23GBAC008); and
• 12m at 1.3 g/t from 44m, including 4m at 2.4g/t (23GBAC022).

“It is exciting to be back on the ground and drilling,” Great Southern Mining (ASX:GSN) managing director Matthew Keane said.
“This targeted program will see GSN return to the Golden Boulder prospect and follow up successful 2021 and 2023 drilling programs which intercepted high grade gold along three mineralised trends.
“Drilling has already defined up to 1.6km of mineralised strike and the upcoming program aims to confirm continuity, as well as testing depth extents.
“We also aim to test new targets that which have been defined by ongoing targeting.”

Primed for a major gold discovery

GSN’s Duketon Gold Project sits in the Duketon–Laverton major fault zone within the Eastern Goldfields Province, where there is a semi-regular distribution of major gold camps (+2Moz) on 30 to 40 kilometre intervals.
Notably, the company’s tenure sits in a 75km stretch yet to yield a major gold deposit, which given the lack of modern exploration bodes well for a significant discovery.
New gold anomalies have been defined in the north-east of the Amy Clarke prospect along the interpreted Garden Well mineralised trend – which is host to Regis Resources’ (ASX:RRL) ~5Moz Garden Well deposit.
Recent geochemistry surveys have also strengthened the prospectivity of the Boundary prospect – also along the Garden Well trend – where surface gold anomalism is up to 10 times greater than other prospects located on GSN’s tenure.
“GSN’s tenure remains highly underexplored with many target areas having virtually no drilling since Sons of Gwalia conducted broad spaced, shallow regional vacuum and air core programs in the 1990s,” Keane said.
