Power Minerals Limited (ASX: PNN) has announced further high-grade rare earths results from drilling at its Eyre Peninsula Project, South Australia.
“These are highly exciting further results from our drilling at Dickson Well and demonstrate potential for rare earths mineralization. These results are comparable and even exceed those reported by other explorers and developers from clay-hosted REE deposits in Brazil, as well as those commonly reported from China,” said Mena Habib, managing director.
Drilling returned 3m averaging 5,025ppm (0.5%) total rare earth oxide (TREO), including 1473ppm magnet rare earth oxide (MREO) from 43m in PKD23-139 at Dicksons Well target.
Drillhole PKD23-139 returned 3m averaging 5,025ppm (0.5%) TREO which included 1,473ppm MREO, or 28.9% of TREO, from 43m.
In addition, on screening to -5 µm, the interval returned 3m averaging 10,253ppm (or 1.0%) TREO which included 3,078ppm (0.3%) MREO from 43m. The hole also returned 1m averaging 7,114ppm TREO which included 2,204ppm MREO (31% of TREO), which upon screening to -53 µm, returned 14,152ppm or 1.4% TREO, including 4,412ppm MREO from 44m. PKD23-139’s REO interval of 6m averaged 0.61% TREO when screened and using a minimum cut-off of 0.1% TREO.
The company has explained that A 3m sample from PKD23-139, from 43-46m, was submitted to laboratory Bureau Veritas (Adelaide) for clay analyses and confirmed this interval contains 52.8% material over 45um.
The analyses demonstrated the vast majority of valuable rare earths occur in the smaller particles. By separating the ore through simple size beneficiation, the larger particles could be removed from the downstream process.
“There is potential for further exploration at Dickson Well, and on the basis that our initial drilling was completed on 400m spacing, closer spaced drilling will be required to firm up our understanding of the mineralization,” said Habib. “We plan to use geophysical modelling to define further drill targets for a planned next phase of drilling to advance this exciting REE opportunity.”
