Power Minerals (ASX:PNN) unveils high-grade niobium and tantalum potential in Brazil

Power Minerals (ASX:PNN) has revealed a promising mineralisation profile at its Tântalo Project in Brazil, following initial reconnaissance sampling that confirmed high concentrations of niobium, tantalum, and rare earth elements (REE).

The findings have bolstered confidence in the project’s potential, with plans for a maiden drilling program on the horizon.

Highlights

• High-grade results from the artisanal workings include:
  • 47.3% Nb₂O₅ and 20.7% Ta₂O₅ with 3,251 ppm partial REO.
  • 23.8% Ta₂O₅ and 31.8% Nb₂O₅ with 6,775 ppm partial REO.
  • 25.0% Ta₂O₅ and 11.2% Nb₂O₅ with 10,422 ppm partial REO.

The samples, drawn from pegmatite intrusions, were collected in the project’s northern sector, where artisanal workings have been prevalent.

According to Managing Director Mena Habib, these findings are a promising indicator of the project’s exploration potential.

“These are exciting results from our first-pass sampling program,” Habib remarked. “They confirm that high-grade niobium-tantalum-REE mineralised pegmatites are also present within our Tântalo Project. The results have provided a strong level of initial confidence in the Project’s exploration potential.”

Strategic Path Forward

With these encouraging results, Power has entered a 60-day due diligence phase in line with its option to acquire the Tântalo Project, which spans 5,780 hectares and includes various “Permissão de Lavra Garimpeira” permits.

These results set the stage for Power’s strategy to produce a niobium-tantalum concentrate using low-cost gravity separation, aimed at prospective offtake partners.

Power Minerals sampling approach has been cost-effective, focusing on selective rock-chip sampling from outcropping pegmatite areas.

The use of rapid, concentrate-based sampling allows for a high-level assessment without extensive preparatory work, making it an efficient first step.

These findings complement the company’s existing Nióbio Project nearby, creating the potential for a strategically aligned Brazilian portfolio centred on critical minerals.
