DY6 Metals (ASX:DY6) has unveiled promising developments at its Tundulu rare earth element (REE) and phosphate project in southern Malawi, with a review of historical data revealing the presence of high-grade gallium mineralisation starting right from the surface.

A detailed examination of diamond and reverse circulation drilling conducted in 2014 indicated robust results, with 4,901 assays assessed for gallium content. Impressively, 27.7% of these samples contained more than 40 grams per tonne (g/t) of gallium oxide. This marks a significant step for DY6 Metals as gallium continues to experience rising demand, particularly within the booming electronics and semiconductor sectors.

To further advance the project, DY6 has partnered with Perth-based Auralia Metallurgy to conduct preliminary metallurgical tests. These tests, using a select bulk sample from Tundulu, aim to determine the feasibility of producing separate concentrates of rare earths and phosphate.

Among the standout assay results, the highest-grade intercept recorded was a substantial 74 metres at 93.26g/t gallium oxide and 1.56% total rare earth oxides (TREO) starting from 72 metres depth. Notably, this interval included a remarkable 14 metres at 202.79g/t gallium oxide and a peak of 310.46g/t gallium oxide combined with 5.68% TREO between 97m and 98m. Other strong results include 53 metres at 72.79g/t gallium oxide from surface and 30 metres at 94.63g/t gallium oxide starting from surface as well, underlining the significant mineralisation potential.

Interestingly, while some elevated grades were detected in saprolite clays, others were found deeper within fresh rock, suggesting a wide distribution of high-value materials. Despite these encouraging signs, only 40% of the highly prospective area at Tundulu has undergone drill testing to date, leaving considerable room for discovery. Areas such as Nathace Hill and Tundulu Hill have been identified as key targets for further exploration.

Most of the earlier drilling focused on Nathace Hill, characterized by REE apatite-hosted carbonatites and feldspathic breccia formations. Additional mineral-rich carbonatite bodies have been located at Tundulu Hill to the east and Makhanga Hill to the west — both of which remain unexplored and show promise for rare earth and niobium mineralisation.

DY6 Metals views the REE mineralisation at Nathace Hill as open towards the south and west, potentially extending well beyond current boundaries. With China still dominating global raw gallium supply, these findings place DY6 in a strategic position amid a tightening market.
