Rainbow Rare Earths Ltd (LON:RBW) has completed a structural and lithological review of the Gakara rare earths project in Burundi which has confirmed high priority areas for the group's ongoing exploration programme.
The results of the structural review and other historical mining and exploration data are being incorporated into 3D models of mineral resources and exploration targets in compliance with the standards defined in the JORC Code, the company said.
Trial mining and processing continues to demonstrate that high total rare earth oxide (TREO) grade ore sourced from across the licence area has similar metallurgical and mineralogical characteristics
Rainbow continues to operate trial mining and processing activities, demonstrating that the ore from veins found across the licence area is amenable to simple processing, via gravity separation, to produce a high-grade concentrate averaging between 52% and 58% TREO and suitable for direct shipping.
The ore has minimal radioactive elements or other deleterious by-products often associated with rare earth projects.
"Since my appointment as CEO in August 2019 my focus has always been to develop a deeper understanding of the deposit to realise the enormous potential it has to offer,” Rainbow chief executive George Bennett said in a statement.
“Understanding the structural controls that gave rise to the mineralisation is a key element to this. Incorporating this knowledge into our 3D mineralisation models alongside the existing mining and drilling data will allow our initial JORC resource base to better reflect our potential and help drive our future exploration activities in the correctly targeted manner,” he added.
