Power Minerals (ASX:PNN) has confirmed its Tantalo project in Brazil is prospective not only for tantalum – but REEs and niobium, too.
That claim comes on the back of due diligence recon sampling on-site the Brazilian acreage with niobium, tantalum and REEs all found at the location of formerly cut amateur mining operations.
Results highlighted by Power included samples of 47% niobium and 21% tantalum with 0.32% “partial” rare earth oxides (REOs).
Others included 24% tantalum and 32% niobium and 0.67% REOs; a third batch, 25% tantalum and 11% niobium with 1.4% “partial” REOs.
“The concentrate samples were pressed into a pellet after sample preparation and then analysed by industry standard XRF to provide quantitative oxide results,” the company wrote of its method on Thursday.
“Additional elements were measured but only by qualitative XRF and these have not been reported because their absolute values are unreliable.
“These qualitative analyses did report the presence of gold, platinum, and other REE’s but until further analyses are complete their significance is uncertain.”
This leaves Power Minerals now ‘moving rapidly’ to drilling these target areas of interest. Samples were collected in the northwestern pocket of the project permit boundaries.
Further artisanal workings are known at the project location and geotechs will run further field sampling activities at that site, too. All in all, the company hopes to offer a niobium-tantalum concentrate to some offtake partner down the line.
