Flint Drilling Underway: Will ACM’s Tenure Expansion Near San Juan Pay Off?
Australian Critical Minerals has commenced its first diamond drilling program at the Flint gold-silver project in Peru, targeting a large hydrothermal system. The company has also expanded its tenure close to the San Juan silver project, enhancing its exploration footprint.
- Maiden ~1,850m diamond drilling program underway at Flint
- First drill hole targeting multiple high-sulphidation epithermal zones
- Expanded tenure brings ACM within 400m of Peñoles’ San Juan Project
- Deployment of advanced ANCORELOG multi-sensor core logging technology
- Drilling aims to confirm mineralisation and assess system scale
Drilling Begins at Flint Gold-Silver Project
Australian Critical Minerals Ltd (ASX:ACM) has taken a significant step forward in its Peruvian exploration strategy with the commencement of a maiden diamond drilling program at the Flint gold-silver project. The program, planned for approximately 1,850 metres across four holes, marks the first systematic drill test of a hydrothermal system extending over a striking 4-kilometre zone.
The initial drill hole, FL_DDH001, is now underway following successful mobilisation and completion of access and drill pad construction. This early progress sets the stage for uninterrupted drilling operations targeting zones interpreted to host high-sulphidation epithermal gold-silver mineralisation, supported by historic geochemical and geophysical data.
Strategic Tenure Expansion Near Major Silver Producer
In parallel with drilling, ACM has expanded its tenure westward, consolidating its footprint across the broader hydrothermal system. This expansion positions the company within approximately 400 metres of the San Juan Project, owned by Peñoles, one of the world’s largest refined silver producers with a market capitalisation around US$17 billion. The proximity to San Juan offers ACM a strategic advantage, potentially tapping into a district-scale mineralised system.
The newly applied concessions cover areas where recent geophysical surveys, including Natural Source Audio-frequency Magnetotellurics (NSAMT), suggest the hydrothermal system may be more extensive than previously understood. This expanded ground provides ACM with flexibility for future development, including potential processing and infrastructure sites.
Innovative Core Logging Enhances Exploration Efficiency
To maximise the value of drilling data, ACM is deploying the DMT ANCORELOG multi-sensor core logging system. This advanced technology integrates hyperspectral scanners, X-ray fluorescence (XRF), and high-resolution optical imaging to deliver rapid, high-fidelity geological data. The system enables real-time insights into alteration minerals and geochemical signatures, improving targeting precision and reducing exploration risk.
By automating and digitising core analysis, ACM expects to accelerate decision-making and refine its geological models dynamically as drilling progresses. This approach represents a modern, data-driven exploration workflow that could set a new standard in the region.
Looking Ahead
With drilling underway and tenure expanded, ACM is well positioned to unlock the potential of the Flint project’s large-scale hydrothermal system. The company plans to provide regular updates on drilling progress and initial assay results, which will be closely watched by investors and industry observers eager to see if the promising geophysical targets translate into significant mineral discoveries.
Bottom Line?
ACM’s maiden drilling and tenure expansion at Flint could redefine its position in Peru’s gold-silver landscape; next steps will be critical.
Questions in the middle?
- What initial assay results will reveal about the scale and grade of mineralisation at Flint?
- How will the proximity to Peñoles’ San Juan Project influence ACM’s development strategy?
- Can the ANCORELOG technology materially accelerate exploration success in this terrain?
