Hamelin Gold Unveils Promising Gold Mineralisation at West Tanami Project
Hamelin Gold Limited (ASX:HMG) has announced encouraging results from its gold exploration drilling programs in Western Australia's Tanami Province, with shallow bedrock gold mineralisation identified at the Fremlins South prospect. The Hamelin Gold West Tanami exploration results demonstrate significant potential in this underexplored region of Western Australia.
The company's systematic approach to exploration is yielding promising discoveries that could establish the West Tanami as an important new gold district. With multiple drill programs currently underway, investors can anticipate a steady flow of results in the coming months.
New Gold Zone Emerging at Fremlins South
Hamelin Gold West Tanami exploration results have successfully outlined a 600-metre long, north-northeast trending zone of shallow gold mineralisation, highlighted by several promising intercepts including:
- 10 metres @ 1.01 g/t Au from 24 metres in TLR0043A
- 4 metres @ 0.31 g/t Au from 44 metres in TLR0060
- 22 metres @ 0.34 g/t Au from 22 metres in TLA0087
- 10 metres @ 0.42 g/t Au from 30 metres in TLA0050
- 2 metres @ 1.41 g/t Au from 42 metres in TLR0039
The discovery is particularly significant as it's located just 14 kilometres south of the Coyote Gold Mine in the West Tanami region. The mineralisation was identified through a 2,246-metre RC drill program that was co-funded through the WA Government Exploration Incentive Scheme (EIS).
"Initial results from our broad spaced RC drill program at South Fremlins has provided a clear focus for a follow up drill program, that is in progress. The West Tanami is a vast and unexplored region of WA. Hamelin has been systematically applying new exploration technologies and concepts to unlock the gold potential of this district." – Peter Bewick, Managing Director
Accelerating Exploration Across Multiple Prospects
Hamelin is maintaining exploration momentum with several concurrent programs that will further test the Hamelin Gold West Tanami exploration results:
-
Fremlins South: A follow-up 15-hole aircore program is currently underway to test the core of the 600-metre long target zone, with results expected in November 2025.
-
Jazz Prospect: A 21-hole, 3,041-metre RC drill program has been completed at the Jazz prospect, located at the western end of the Sultan Gold Corridor. Results are expected in October 2025, with diamond drilling planned contingent on positive results.
-
Regional Aircore Program: A 5,000-metre aircore drill program has commenced testing six regional gold targets including Newkirk, Camel North, Harkonnen, Ginger, Halleck, and Hutch's North.
Understanding Dilational Jogs in Gold Mineralisation
A key finding from the Fremlins South exploration is the identification of what geologists interpret as a dilational jog within the mineralised corridor. Dilational jogs are structural features that form when there's movement along an irregular fault plane, creating zones where pressure decreases and fluids carrying gold can precipitate.
These structural features are significant because they often host concentrated gold mineralisation, creating zones where high-grade gold shoots are more likely to occur. Hamelin's targeting of this 600-metre long, sigmoidal-shaped feature demonstrates their systematic geological understanding and targeted exploration approach.
The Science of Gold Traps: How Dilational Jogs Work
Dilational jogs represent an important concept in structural geology related to gold exploration. When rocks move along fault lines, irregularities in the fault surface can create areas where the rock pulls apart slightly. These openings become natural traps for mineral-rich fluids circulating through the earth's crust.
In gold exploration, these structures are particularly valuable targets because:
- The decrease in pressure when fluids enter these spaces causes minerals, including gold, to precipitate out of solution
- The geometry of these jogs often creates a network of interconnected openings that can host significant volumes of mineralisation
- The orientation of these structures can help predict the direction and extent of potential gold shoots
Hamelin Gold West Tanami exploration results highlight a textbook example of this geological feature, with the company's targeting strategy focused on the 600-metre long sigmoidal-shaped structure at Fremlins South.
Strategic Position in an Emerging Gold Province
The West Tanami Project is considered highly prospective for multi-million ounce orogenic gold deposits, similar to Newmont's Tier 1 Tanami Operations in the Northern Territory. Hamelin's strategic landholding in this underexplored region positions them well to make significant discoveries.
The company is applying modern exploration technologies to unlock the gold potential of this district, including:
- CSIRO-developed Ultrafine® analytical technology for surface sampling in sand-covered terrain
- Systematic aircore and RC drilling programs
- Advanced structural geological interpretations
Investment Thesis: Early-Stage Explorer with Strong Backing
Hamelin Gold presents an interesting opportunity for investors looking for exposure to gold exploration in a promising but underexplored region. Key factors supporting the investment case include:
-
Strategic Location: The West Tanami province is prospective for high-value, large-scale gold deposits similar to Newmont's Tier 1 Tanami Operations.
-
Strong Corporate Backing: Hamelin is supported by significant shareholders including Gold Fields Limited (JSE/NYSE:GFI) and Vault Minerals Limited (ASX:VAU).
-
Government Support: Multiple drill programs co-funded through the WA Government Exploration Incentive Scheme, reducing exploration costs.
-
Multiple Near-Term Catalysts: Results expected from several drill programs between October and November 2025.
-
Systematic Approach: The company is methodically applying new exploration technologies and concepts to unlock the gold potential of the district.
Why Investors Should Watch Hamelin Gold
With multiple exploration programs underway and results pending in the coming months, Hamelin Gold West Tanami exploration results offer investors exposure to potential discovery upside in a proven gold province. The shallow nature of the mineralisation at Fremlins South is particularly encouraging, as it could indicate favourable economics if a viable resource is ultimately defined.
The company's methodical approach to exploration, combined with government funding support and strong corporate backing, provides a solid foundation for ongoing exploration success. As results from the Jazz prospect and regional targets arrive in October-November 2025, investors will gain further insight into the potential scale of gold mineralisation across Hamelin's extensive West Tanami Project.
Regional Context: The Tanami Gold Province
The Tanami Province spans across the Western Australia-Northern Territory border and has emerged as one of Australia's premier gold regions. The province hosts Newmont's world-class Tanami Operations, which produce approximately 500,000 ounces of gold annually.
Despite this proven endowment, large portions of the Tanami Province, particularly the Western Australian side where Hamelin operates, remain underexplored. This underexploration is largely due to:
- Remote location and challenging logistics
- Extensive sand cover masking bedrock geology
- Historical focus on the Northern Territory side of the province
Hamelin Gold West Tanami exploration results represent part of a systematic effort to apply modern exploration techniques to this frontier region, potentially unlocking significant value for shareholders if successful discoveries can be made.
