29.4km NSAMT Survey Set to Guide 3,000m Drilling at Flint Gold Project
Australian Critical Minerals has launched a cutting-edge geophysical survey at its Flint Project in Peru, aiming to refine drill targets within a prolific gold belt ahead of a planned 2026 drilling campaign.
- 29.4 line-kilometre NSAMT geophysical survey underway
- Flint Project located in a +50Moz gold belt in northern Peru
- 3,000m diamond drilling planned for early 2026
- Survey to produce 3D resistivity models for optimal drill site selection
- Drilling permissions are well advanced for rapid program commencement
Strategic Positioning in a World-Class Gold Belt
Australian Critical Minerals (ASX – ACM) has taken a significant step forward at its Flint Project, situated in Peru’s La Libertad region, a prolific mineral province boasting over 50 million ounces of gold resources. The project lies adjacent to Peñoles’ San Juan copper project, underscoring the geological richness of the area. This proximity to established deposits enhances the strategic value of Flint, positioning ACM to potentially unlock substantial gold and silver mineralisation within a large high-sulphidation epithermal system.
Deploying Advanced Geophysics to Refine Targets
To sharpen its exploration focus, ACM has mobilised Southern Rock Geophysics and Arce Geophysics to conduct a 29.4 line-kilometre Natural Source Audio-frequency Magnetotellurics (NSAMT) survey. This sophisticated technique maps the electrical resistivity of subsurface rocks, providing a three-dimensional view of geological structures and fluid pathways that are often associated with mineralisation. By integrating this data with historic induced polarisation surveys, the company aims to delineate high-priority drill targets with greater precision.
Pathway to Drilling and Exploration Upside
The NSAMT survey is a critical precursor to a planned 3,000-metre diamond drilling program scheduled for early 2026. Importantly, drilling permits are already well advanced, allowing ACM to transition swiftly from geophysical modelling to on-ground exploration. The survey covers over four kilometres of strike within a 6 km² alteration footprint, supported by more than 500 rock samples and historic geochemical data, all pointing to a robust mineralised system ripe for testing.
Experienced Partners and Local Expertise
Southern Rock Geophysics brings over two decades of experience in the Andes, while Arce Geophysics has been a leading local consultancy in Peru since 1960. This partnership combines international technical expertise with deep regional knowledge, enhancing the quality and reliability of the geophysical data. Their work is expected to expand the exploration footprint beyond previously identified anomalies, potentially revealing new zones of mineralisation.
Looking Ahead
Executive Chairman Dean de Largie emphasised the compelling scale and geological setting of the Flint Project, highlighting the excitement around the upcoming drilling campaign. As ACM integrates modern geophysical techniques with historic data, the company is poised to unlock significant value in one of the world’s most richly endowed mineral belts. The coming months will be pivotal as the survey results emerge and drilling plans crystallise.
Bottom Line?
With advanced geophysics underway and drilling permissions secured, ACM is set to accelerate exploration at Flint, potentially reshaping its resource outlook.
Questions in the middle?
- What specific targets will the NSAMT survey highlight for the 2026 drilling program?
- How might the integration of historic and new geophysical data redefine the project’s exploration footprint?
- What timeline can investors expect for initial assay results following the drilling campaign?
