Magnum Mining and Exploration is set to launch a substantial 10,000-metre auger drilling program at its Piracanjuba prospect in Brazil, aiming to define a maiden resource for its promising ionic adsorption clay rare earth element deposit.
- 10,000m auger drilling planned across Piracanjuba prospect
- Drilling targets JORC-compliant Exploration Target and maiden Mineral Resource Estimate
- High recoveries of TREO (up to 75%) and MREO (up to 94%) confirmed
- Exceptional assays with up to 3,971ppm TREO and 1,360ppm MREO
- Program to commence 1 April 2026, accelerating exploration efforts
A Step Up in Rare Earth Exploration
Magnum Mining and Exploration Limited (ASX:MGU) has announced plans to significantly ramp up exploration at its Piracanjuba prospect within the Azimuth Rare Earth Element Project in Brazil. The company intends to undertake an extensive 10,000-metre auger drilling program starting from 1 April 2026. This move follows encouraging early results that have confirmed the presence of ionic adsorption clay (IAC) hosted rare earth element (REE) mineralisation, a style of deposit prized for its potential to yield high-value strategic metals under relatively mild processing conditions.
Unlocking Scale and Defining Resources
The drilling campaign is designed with a dual focus: wide-spaced holes will test the lateral extent of the mineralisation across the prospect’s broad 85-kilometre geophysical footprint, while tighter-spaced drilling will concentrate on previously identified high-grade intercepts. The ultimate goal is to delineate a JORC-compliant Exploration Target and progress towards a maiden Mineral Resource Estimate (MRE), critical milestones that could materially enhance the project’s valuation and attractiveness to investors.
Promising Assay Results and Recovery Rates
Recent assays have delivered compelling data, with total rare earth oxides (TREO) reaching up to 3,971 parts per million and medium rare earth oxides (MREO) up to 1,360 ppm. Even more notable are the desorption recovery rates, which have demonstrated up to 75% for TREO and an impressive 94% for MREO under mild leaching conditions. These figures underscore the potential for efficient extraction of critical rare earth elements, which are essential components in high-tech and clean energy applications.
Strategic Location and Geological Context
Located within the Azimuth 125° Lineament, a significant crustal-scale structural feature, the Piracanjuba prospect benefits from geological settings that have historically hosted valuable mineral deposits. Its proximity, approximately 50 kilometres, to CMOC’s Catalão Project, one of Brazil’s highest-grade niobium mines, further highlights the region’s mineral potential. Magnum’s Chairman, Michael Davy, emphasised that the recent results have materially de-risked the project and justified a more aggressive exploration approach to unlock the system’s broader scale.
Looking Ahead
The upcoming drilling program represents a pivotal phase for Magnum Mining as it seeks to transition from discovery to resource definition. While the forward-looking nature of exploration means uncertainties remain, the combination of high-grade assays, strong recovery rates, and a large geophysical footprint positions Piracanjuba as a rare earth project with significant upside potential. Market watchers will be keenly awaiting assay results from this program, which could set the stage for further development and investment interest.
Bottom Line?
Magnum’s aggressive drilling push at Piracanjuba could soon transform promising assays into a defined rare earth resource, reshaping its growth trajectory.
Questions in the middle?
- Will the drilling confirm a JORC-compliant Mineral Resource Estimate at Piracanjuba?
- How might the high recovery rates under mild leaching impact project economics and processing choices?
- What are the timelines and potential hurdles for advancing from exploration to development?
