Pensana’s Angola discovery shows encouraging REE mineralisation

Although it is still early stage, London listed Pensana has reported results from their Coola and Sulima West Rare Earth Element (REE) exploration programmes that are in some cases of a higher grade that those found at the company’s Longonjo REE project in Angola.

The Coola license is 16km north of Longonjo in the Huambo Province of central Angola. Sulima West is located 50km from the Coola carbonatite and was only recently identified. Pensana’s geologists identified highly anomalous technology metals, including rare earths, scandium and fluorite in soils surrounding the 7500km2 Coola license area in 2020. Activities were halted for a few months because of Covid-19 lockdowns before it resumed in the third quarter of 2021.

According to Pensana’s Exploration Manager, Grant Hayward, Sulima West has been intersected by ten large exploration trenches up to 90m in length, coinciding with a large radiometric anomaly. The trenches are understood to have been excavated during 1960-61 but have not been followed up with modern exploration methods,” Pensana said in a statement.

Mineralogical studies of the Coola carbonatite identified the rare earth mineral to be bastnäsite, which occurs as discrete veins, veinlets, and segregations within the carbonatite.

“We are extremely encouraged by the initial results from both Coola and Sulima West and are eager for the field season to commence to follow up on these exciting targets. Whilst it is early stage, these are very large structures reporting grades which are in some cases higher than those for Longonjo. There are several radiometric anomalies and ring structures still to be evaluated, and we very much look forward to further exploration in 2022 with the easing of Covid related travel restrictions,” says Hayward.
