Power Minerals Ltd (ASX:PNN) Commences 2nd Phase Drilling at Santa Anna
6 August 2025
Price Sensitive Announcement $
Highlights:
1,000m auger drill program underway at Santa Anna Project, Brazil to follow-up broad zones of niobium and high-grade REE intersected in maiden drill program
Drilling designed to extend Project’s mineralised footprint to the east and south-east of initial drilling, targeting shallow niobium and REE in yet to be tested areas of the Santa Anna Alkaline Complex
The program will provide regular samples to assist in developing the Project’s mineralisation model – and provide data for an Exploration Target and Mineral Resource Estimate (subject to results)
Drilling is expected to be completed in the current month and results will be released when available
Power also plans to conduct deeper drilling into the fresh rock at the current target area following the current auger drilling program
Power’s drilling programs at the Santa Anna Project form part of its due diligence to potentially acquire the Project
Power has an option to acquire the entire 17.05km² Santa Anna Project which hosts high-grade Nb, REE and Ga in the upper weathered portion
Power’s drilling to date has highlighted the Project’s expansion potential at depth, and ~89.3% of the 5.8km² Alkaline Complex surface area is untested, indicating a potential significant scale exploration opportunity
Overview:
Power Minerals Limited (ASX: PNN, Power or the Company) is pleased to
announce the commencement of the second phase of drilling at the Santa
Anna niobium-REE-gallium carbonatite project (“Santa Anna” or “the Project”) in Goiás State, in the central region of Brazil.
Drilling will follow up Power’s recently completed maiden 29-hole, 2,272m program at the Santa Anna Project1. It is designed to extend the Project’s mineralised footprint to the east and south-east of the maiden drilling which intersected multiple wide zones of niobium mineralisation and multiple zones of high-grade rare earth elements (REE) mineralisation.
The second phase program will consist of 1,000m of auger drilling for approximately 60 holes, targeting shallow niobium and REE mineralisation in yet to be tested areas of the Santa Anna Alkaline Complex (Figure 1).
The program will test a large area around known mineralised drillholes via a grid-based drill plan. It is envisaged that the drilling will return regular spaced sampling data, which will assist in further developing the Project’s mineralisation model – and providing data for the delineation of an Exploration Target and Mineral Resource Estimate (subject to results).
Drilling is expected to be completed in the current month and results will be released when available. The Company then plans to conduct deeper, reverse circulation (RC), drilling into the fresh rock beneath the weathered zone at the current target areas following the conclusion of the current auger drilling program.
Power’s drilling programs at Santa Anna form part of its due diligence to potentially acquire the Project, pursuant to its exclusive option to acquire the Santa Anna Project2
Company Notes:
Power Minerals Ltd Managing Director, Mena Habib, says “The second phase drilling program at the Santa Anna Project will allow us to rapidly test new untested target areas in the Project’s tenure and provide additional key data as a part of our due diligence for the potential acquisition of the Project, and for Exploration Target and Mineral Resource Estimation purposes.
The current drilling is an auger program designed to target niobium and REE mineralisation in the shallow, weathered zone in an area adjacent to our maiden reverse circulation drilling program. On conclusion of this drilling, we then plan to conduct deeper, RC drilling to test for
mineralisation at depth in the fresh rock in this area. These drilling programs are all designed to extend the Project’s niobium and REE mineralised footprint near surface and at depth in the
carbonatite – and further validate our exploration model for the Project.”
