Great Southern Mining Ltd
New Mining Discoveries and Strategic Development Positioning
Great Southern Mining new gold discovery at the Mon Ami Gold Project represents a significant milestone for the company, with recent aircore drilling results revealing potential new gold lodes parallel to the existing mineral resource. The programme targeted zones north and northwest of the current 1.56Mt at 1.11 g/t Au for 55.5koz gold JORC 2012 resource, with results pointing to significant expansion opportunities that could transform the project's development prospects.
The standout intercepts include 2m at 2.56 g/t Au from 62m within a broader zone of 10m at 0.77 g/t Au in hole 25MAAC022, and a promising 2m at 1.86 g/t Au from 20m in hole 25MAAC0039. This latter intercept is particularly significant as it sits proximal to previous shallow intercepts, including a historic 4m at 2.50 g/t Au from 69m, suggesting the discovery of a new parallel lode system.
Managing Director Commentary
"The recent assay results at Mon Ami highlight the potential for new gold lodes offset and parallel to the existing resource. We are building a better understanding of the mineralised system and we believe there may be several high-grade splays associated within the broader Barnicoat Shear Zone." – Matthew Keane, Managing Director

New Parallel Lode Discovery Opens Growth Potential
According to the announcement, the most significant development from this drilling campaign is the identification of what appears to be a new parallel lode structure north of the existing Mon Ami resource. The Great Southern Mining new gold discovery represents a breakthrough in understanding the broader mineralisation system across the project area.
The intercept of 2m at 1.86 g/t Au from 20m in hole 25MAAC0039 complements several historic shallow intercepts in the same zone, building a compelling case for a repeat of the main orebody geometry. Furthermore, this discovery aligns with systematic exploration techniques that have proven successful in similar geological environments.
The company reports this discovery is particularly exciting given the shallow nature of the mineralisation, which could significantly enhance the economics of any future mining operation. In addition, the intercept aligns with the company's geological model of multiple high-grade splays within the broader Barnicoat Shear Zone system.
Key Drilling Results Summary:
| Hole ID | Depth (m) | Interval | Grade (g/t Au) | Significance |
|---|---|---|---|---|
| 25MAAC022 | 62-64 | 2m | 2.56 | High-grade core |
| 25MAAC022 | 54-64 | 10m | 0.77 | Broader envelope |
| 25MAAC0039 | 20-22 | 2m | 1.86 | New parallel lode |
| 25MAAC0039 | 62-64 | 2m | 0.74 | Secondary zone |
The systematic approach to testing geochemical anomalies has proven successful, with the programme confirming saprolite-hosted gold mineralisation below previously defined surface anomalies. Consequently, this methodology validates the company's exploration strategy and positions it for continued success in identifying additional mineralised zones.
Understanding Aircore Drilling in Gold Exploration
Aircore drilling represents a cost-effective exploration technique that uses compressed air to drill through softer, weathered rock near the surface. The method is particularly valuable in the early stages of gold exploration as it allows companies to test large areas quickly and identify mineralised zones before committing to more expensive reverse circulation or diamond drilling.
For investors, aircore results are significant because they provide the first indication of gold grades and help define target areas for follow-up drilling. While aircore typically only penetrates the upper 50-100 metres of rock, this shallow zone often contains the most economically attractive mineralisation in Western Australian gold deposits due to weathering processes that can concentrate gold values.
Saprolite-Hosted Mineralisation refers to gold deposits found within weathered rock layers formed by chemical breakdown of the original bedrock. These zones often host higher-grade gold concentrations as weathering processes can leach and reconcentrate precious metals.
However, the technique is ideal for projects like Mon Ami, where the company is testing for extensions to known mineralisation and exploring for parallel lode systems that could multiply the resource base. Geochemical anomalies identified through soil sampling guide drill target selection, with elevated gold values in soils indicating potential buried mineralisation below.
Strategic Location and Infrastructure Advantages
Mon Ami's position within Western Australia's renowned Laverton mining district provides significant strategic advantages according to the announcement. The project sits on the Barnicoat Shear Zone, a major geological structure that hosts numerous gold deposits in the region. This positioning offers several key benefits that could enhance project economics and support future mining operations.
Infrastructure & Development Advantages:
• Located on a granted Mining Licence with existing permits
• Proximity to operating and planned gold processing facilities
• Access to established mining infrastructure and skilled workforce
• Advanced permitting status reduces development timeline and costs
The project's location within 40km of operating mills means Great Southern Mining could potentially process ore through toll treatment arrangements, significantly reducing capital requirements for development. This model has proven successful for many junior miners in the Laverton district, allowing companies to generate revenue without constructing dedicated processing facilities.
Consequently, the Barnicoat Shear Zone represents a major fault system that has concentrated gold mineralisation through geological processes over millions of years. Shear zones create pathways for gold-bearing fluids to deposit precious metals in economic concentrations, making them prime exploration targets in Western Australia's goldfields.
Exploration Upside and Future Targets
The announcement states that the Mon Ami deposit remains open in several directions, with particular potential to the north, northwest, and down-dip. One of the most compelling aspects of the project is the limited drilling outside the current resource area, suggesting substantial untested potential that could yield additional Great Southern Mining new gold discovery results.
Historic deep drilling has returned exceptional results according to company records, including:
• 2m at 27.5 g/t Au from 173m in hole MLRC036
• 10m at 2.7 g/t Au from 241m, including 5m at 5.2 g/t Au in hole 21MARC010
• 21m at 1.0 g/t Au from 255m in the same hole
These deep intersections demonstrate the deposit's potential to extend well below the current resource model, while the recent shallow discoveries suggest parallel systems could multiply the total gold endowment. Furthermore, the company's geological interpretation indicates multiple high-grade splays within the broader shear zone system.
Management's Planned Next Steps:
- Assessment of recent drill results and geological modelling
- Planning of follow-up drilling to define new parallel lode
- Resource extension drilling in multiple directions
- Evaluation of development opportunities given current gold prices exceeding $7,300/oz
The systematic exploration approach has successfully identified new targets through geochemical surveys, with soil sampling revealing anomalous gold trends up to 100ppb Au northwest of the existing resource. These anomalies suggest potential parallel lode systems that could significantly expand the project's gold inventory.
What Makes This Discovery Significant for Future Exploration?
The Great Southern Mining new gold discovery validates the company's geological model and demonstrates the effectiveness of systematic exploration techniques in identifying new mineralised zones. In addition, the shallow nature of the new parallel lode suggests potential for low-cost mining operations that could enhance project economics significantly.
This discovery pattern indicates the presence of multiple mineralised systems within the broader Barnicoat Shear Zone, suggesting considerable exploration upside across the company's tenement package. For instance, similar geological environments have historically yielded multiple parallel lodes that collectively form substantial gold resources.
