Greenpower finds LCT pegmatite system

Greenpower Energy (ASX: GPP) has identified lithium-cesium-tantalum (LCT) pegmatites with geochemistry suggesting they occur on a district scale at the Morabisi lithium-tantalum rare earth elements project.

Stream geochemistry has identified three strong target areas with LCT indicator elements. These three areas are Turesi Ridge, Banakaru (20 kilometre ridge) and East Camp (20 kilometre ridge).

With regard to the broader project, management said the historic mines at Robello rare earth elements project were very evident with several remnants of heavy equipment left behind by the Morabisi Mining Company.

 There was evidence of the impact of floods, and while this made it difficult to find a suitable location to dig test pits, two locations delivered promising sample material, producing a heavy concentrate samples for Coltan.

Results from pit sampling returned high grades of up to 1.03% Nb205 and 0.25% Ta205. Management is of the view that some of the results are likely ore grade in an alluvial mining scenario, but this sample was collected as a standard stream sediment sample and not a gravel concentrate.

As rare earth elements are heavy minerals, higher grades would be expected closer to bedrock.

Executive chairman Gerard King said, “The results received to date are very encouraging and indicate a district scale LCT pegmatite system is evident at Morabisi, in addition to what looks potentially like an economic alluvial REE, tantalum and niobium deposit within the same PGGS permit area”.

Discussing upcoming objectives, King said, “The joint venture is currently finalising its views on phase 2 with the general view being to immediately employ a portable track mounted diamond drill rig to test LCT pegmatites in fresh rock and better understand the potential of the ore body”.
