Santa Anna’s Untapped Depths Pose Risks and Rewards for Power Minerals’ Next Phase
Power Minerals has completed a cutting-edge drone magnetic survey over its Santa Anna project in Brazil, revealing new exploration targets and setting the stage for a significant drilling campaign aimed at defining a maiden resource.
- Drone aerial magnetic and elevation survey completed over Santa Anna complex
- New structural features and exploration targets identified
- Project area largely untested below 100 metres depth
- Upcoming reverse circulation drilling campaign planned for up to 10,000 metres
- Maiden Mineral Resource Estimate targeted for first half of 2026
Exploration Innovation at Santa Anna
Power Minerals Limited (ASX – PNN) has taken a significant step forward in its exploration of the Santa Anna Carbonatite Alkaline Complex in Brazil by completing a drone-supported aerial magnetic and digital elevation model (DEM) survey. This advanced geophysical technique has unveiled previously undetected structural features within the complex, which spans approximately 2.5 kilometres. The survey’s high-resolution data promises to refine the geological understanding of the site and pinpoint new high-priority target areas for mineralisation.
Unlocking Untapped Potential
Despite prior drilling efforts, nearly 90% of the Santa Anna complex’s surface remains untested, particularly below 100 metres depth. The drone survey’s preliminary results highlight linear features and magnetic anomalies that were not visible in earlier regional surveys, which had much wider line spacing and lower resolution. These findings suggest the presence of late-stage structural controls that could concentrate mineralising fluids, potentially increasing the prospectivity of the site for niobium and rare earth elements (REE).
Strategic Drilling Campaign on the Horizon
Building on the survey results, Power Minerals is poised to launch a major reverse circulation (RC) drilling campaign targeting up to 10,000 metres, with an initial 2,000-metre phase commencing imminently. This drilling program aims to extend the known mineralised footprint and accelerate the path toward a maiden Mineral Resource Estimate (MRE) expected in the first half of 2026. The new geophysical data will be instrumental in guiding drill hole placement, enhancing resource modelling, and improving logistical planning for field operations.
Context of Acquisition and Project Significance
Power Minerals recently secured 100% ownership of the Santa Anna Project through acquisition, consolidating control over the entire alkaline carbonatite complex. This acquisition aligns with the company’s broader strategy to develop critical mineral assets, including lithium in Argentina and other REE and niobium projects in Brazil. The Santa Anna complex’s geological setting within the Goiás Alkaline Province and its association with significant tectonic features add to its exploration appeal.
Looking Ahead
As Power Minerals advances its exploration efforts, the integration of drone-based geophysics with extensive drilling could unlock substantial value for investors. The company’s methodical approach, combining innovative technology with targeted fieldwork, exemplifies the evolving landscape of mineral exploration. The market will be watching closely as assay results emerge and the maiden resource estimate takes shape, potentially reshaping the outlook for this promising Brazilian asset.
Bottom Line?
Power Minerals’ innovative survey and upcoming drilling campaign could redefine Santa Anna’s resource potential, setting a new benchmark for critical minerals exploration in Brazil.
Questions in the middle?
- How will the new geophysical targets influence the final resource model and drilling priorities?
- What are the expected timelines and milestones for assay results from the upcoming drilling campaign?
- Could the newly identified structural features indicate deeper or higher-grade mineralisation zones?
