Government Grant Validates Mt Berghaus Exploration Strategy
Mantle Minerals (ASX:MTL) has secured a significant vote of confidence from the Western Australian Government with the award of a co-funded drilling grant under the Exploration Incentive Scheme (EIS). This competitive grant will support the drilling of two holes targeting high-priority gravity anomalies at the company's Mt Berghaus Project in Western Australia's resource-rich Pilbara region.
The EIS grant represents more than just financial support—it serves as third-party validation of Mantle's exploration strategy and the prospectivity of the targets identified through recent geophysical surveys. This government backing comes alongside the company's completion of its Mt Berghaus tenement package with the granting of E45/6645, resolving long-standing objections from miscellaneous license holders.
"Securing this EIS grant demonstrates the technical merit of our exploration program and the significant potential of the Mt Berghaus Project," said Mr. Robert Mosig, Director and Competent Person at Mantle Minerals. "With the tenement package now complete and drilling support in place, we're positioned to systematically test these compelling targets."
Four High-Priority Targets Identified Through Advanced Geophysics
Recent gravity surveys at Mt Berghaus have delineated four compelling targets with the potential to host significant mineralisation, similar to how S2 Resources launches major multi-project drilling campaign across various prospective areas.
| Target | Key Characteristics | Significance |
|---|---|---|
| MTB_T1 | Interpreted magnetic intrusive | Untested potential source of mineralisation |
| MTB_T2 | Interpreted magnetic intrusive | Selected for EIS-funded drilling |
| MTB_T3 | Adjacent to known mineralisation | Supported by historical intercepts of 4m @ 1.2 g/t Au and 3m @ 0.9 g/t Au |
| MTB_T4 | Discrete gravity anomaly along magnetic structure | Aligned with potential mineralised conduit |
The most promising aspect of these targets is their shallow depth beneath cover, making them both economically and technically viable drill targets. The upcoming drilling programme will focus on targets T2 and T3, with the dual objectives of validating the targeting techniques and testing for gold mineralisation.
Particularly encouraging is the proximity of target MTB_T3 to historical drilling that returned significant gold intercepts, indicating the fertility of the system and enhancing the prospectivity of the target area.
Understanding Gravity Surveys: A Key Tool in Modern Mineral Exploration
Gravity surveys represent one of the most effective geophysical methods for identifying potential ore bodies beneath cover. These surveys measure minute variations in the Earth's gravitational field, which can indicate the presence of rock masses with different densities.
In gold exploration, gravity surveys can be particularly valuable as hydrothermal alteration associated with gold mineralisation often creates density contrasts detectable by these surveys. Gravity anomalies (areas where gravitational pull differs from surrounding areas) may indicate:
- Concentrations of denser minerals that could host gold
- Structural features like faults that could channel mineralising fluids
- Intrusive bodies that might be associated with mineralisation
The 1VD Gravity Derivative (first vertical derivative) highlighted in Mantle's announcement is an advanced processing technique that enhances subtle gravity features and can more precisely locate the edges of subsurface structures—making target selection more accurate and increasing the probability of drilling success.
For investors, the application of these sophisticated geophysical techniques demonstrates Mantle's technical capabilities and increases confidence in the company's targeting methodology.
Completing the Land Package
In an important development that complements the government grant received by Mantle Minerals, the company has successfully completed its Mt Berghaus tenement package with the granting of E45/6645. This achievement marks the resolution of a protracted application process that had been delayed by objections from miscellaneous licence holders regarding railways and other infrastructure.
The completion of the tenement package is strategically significant as it:
- Provides Mantle with unhindered access to the entire prospective area
- Removes administrative barriers to comprehensive exploration
- Allows for more efficient planning and execution of exploration programmes
- Creates potential for future discoveries across the broader project area
This final tenement grant represents the culmination of efforts first detailed in the company's announcement on 2 November 2022, demonstrating Mantle's persistence in establishing a solid foundation for its exploration activities.
Exploration Roadmap: Clear Pathway to Discovery
Mantle Minerals has outlined a clear progression of exploration activities at Mt Berghaus:
- Finalise planning for the initial drilling campaign – Detailed planning of hole locations, depths, and technical parameters
- Commence drilling of two EIS-supported holes – Testing priority gravity anomalies with potential for gold mineralisation
- Continue geological mapping, sampling, and targeting – Building a comprehensive understanding of the mineral system across the project area
This methodical approach demonstrates the company's commitment to systematic exploration rather than speculative drilling. The EIS co-funding will reduce the financial risk associated with testing these new targets while potentially accelerating the discovery timeline.
While Mantle Minerals receives government grant for its exploration activities, other companies like Vital Metals secure funding through different mechanisms to advance their projects.
The EIS Programme: Supporting Innovation in Exploration
The Exploration Incentive Scheme (EIS) through which Mantle Minerals received its government grant is a well-regarded programme managed by the Geological Survey of Western Australia. The scheme is designed to encourage exploration in greenfield areas by providing co-funding for innovative drilling projects.
What makes the EIS significant for investors:
- Competitive Selection Process: Projects are selected based on technical merit and innovation, providing independent validation of exploration concepts
- Expert Review: Applications are evaluated by technical experts, meaning funded projects have passed rigorous professional scrutiny
- Leveraged Funding: The co-funding approach stretches shareholder capital further while maintaining company control
- Focus on Pioneering Exploration: The programme targets areas and concepts that might not otherwise be tested, potentially leading to new discoveries
The fact that Mantle Minerals has secured this government grant indicates the project's technical soundness and innovative approach, as recognised by industry experts reviewing the applications.
Investment Thesis: Multiple Value Drivers Converging
Mantle Minerals presents a compelling investment opportunity for several reasons:
- Government Validation – The EIS grant provides external validation of the project's technical merit and exploration strategy
- Complete Land Package – With the final tenement granted, Mantle now has unfettered access to the entire prospective area
- Technical Foundation – Advanced geophysical targeting has identified specific anomalies with characteristics of gold-bearing systems
- Proximity to Success – Historical drill results near target MTB_T3 confirm the presence of gold in the system
- Pilbara Gold Potential – The project is located in an emerging gold region that has gained increased attention from major producers
The company's focus on shallow targets is particularly significant from an economic perspective—if successful, shallow discoveries typically have lower development costs and faster pathways to production than deeper deposits. This approach is similar to how Austin Metals identifies new gold targets along strike from existing discoveries.
