Great Southern Mining has released new assay results from its Golden Boulder prospect in Western Australia’s Duketon Belt, with high-grade gold intervals including 4 metres at 11.38 grams per tonne (g/t) from 45 metres, containing 1 metre at 29.71 g/t. The results come from the company’s ongoing 14,000-metre reverse-circulation drilling program and have extended known mineralisation by up to 50 metres down-dip.
The latest 18 holes from the program delivered multiple notable intercepts. One hole returned 9 metres at 3.36 g/t from 127 metres, including 4 metres at 6.77 g/t, while others featured 2 metres at 7.27 g/t from 70 metres and 3 metres at 3.88 g/t from 60 metres. All reported intervals are downhole lengths, with true widths yet to be confirmed.
The company’s 100 per cent-owned Duketon gold project covers 549 square kilometres in the Laverton–Duketon district, capturing key structural corridors including 7 kilometres of the Garden Well trend, 11 kilometres of the Rosemont trend and 8 kilometres of the Erlistoun trend — zones that host major gold deposits elsewhere in the belt.
At Golden Boulder, mineralisation has been traced along three parallel trends: the Main Line, Eastern Line and Ogilvies. Drilling has intersected multiple stacked quartz-vein lodes with disseminated sulphides including pyrite and arsenopyrite, hosted in basalt and minor dolerite. The company is testing whether the network of steep gold-bearing structures continues below and between the shallow workings.
Great Southern Mining managing director Matthew Keane said the company firmly believes that both Golden Boulder and the wider Duketon gold project have potential for a substantial gold endowment.
The assays have also identified high-grade mineralisation in previously undrilled sections, adding to the prospect’s continuity across the first 1.1 kilometres of a 3.5-kilometre mineralised trend.
Analysis
Why This Matters
- The results could enhance the economic case for a future mining operation at Golden Boulder, which is still in the exploration phase.
- For investors in Great Southern Mining, the continuity and grade of intercepts suggest the prospect may be growing in scale and quality.
- The Duketon Belt is a proven gold district, and successful drilling here could attract joint venture or offtake interest.
Background
Great Southern Mining is an Australian gold explorer focused on the Duketon gold project in Western Australia’s northeastern goldfields. The region has been a significant source of gold production, with several operating mines nearby. The company has been conducting a 14,000-metre reverse-circulation drilling program at Golden Boulder, which was discovered through earlier exploration. The current assays are part of an effort to define the extent and grade of the mineralised system.
Key Perspectives
Great Southern Mining: The company is optimistic that the ongoing drilling will demonstrate a substantial gold endowment. Managing Director Matthew Keane has expressed confidence in the project’s potential.
Investors and analysts: The market will be watching for further assay results and any initial resource estimate. The high-grade intervals are encouraging, but true widths and continuity remain to be confirmed.
Skeptics: The reported intervals are downhole lengths, not true widths, so the actual thickness of mineralisation may be less. The project is still at an early stage, and economic viability depends on many factors including metallurgy, depth, and infrastructure.
What to Watch
- Remaining assays from the 14,000-metre program, particularly holes targeting extensions down-dip and along strike.
- Any announcement of a maiden mineral resource estimate for Golden Boulder.
- Movement in Great Southern Mining’s share price, reflecting market reception of the results.
