DY6 Metals Ltd (ASX:DY6) has picked up rare earths (REEs) grading above 3% and phosphorus pentoxide (P2O5) grading beyond 27% through metallurgical sampling at its Tundulu REE and Niobium carbonatite project in Malawi.
During the program, 63 samples were collected from 37 locations, focused on a high-grade 83 metre historical trench at the project, with the highest grade showing 3.35% TREO (total rare earth oxides) and 27.5% P2O5.
Within this result, DY6 also discovered that the average heavy rare earth oxides (HREO) made up 13% of the TREO basket, and that the levels of deleterious elements such as mercury, lead and cadmium in the phosphorus-rich rocks were low and sometimes undetectable.
Heavy rare earth elements included 2.5% Dy (dysprosium) & Tb (terbium).
DY6 is undertaking the metallurgical testing to assess historical studies done at Tundulu, in addition to findings from a 2017 metallurgical report which was completed by previous operators of the licence.
This round of test work – conducted by Nagrom metallurgical and analytical laboratory in Perth – will seek to validate beneficiation results yielded by the previous laboratory.
DY6 is seeking to ascertain the early-stage viability of producing two product streams: a REE commercially saleable concentrate and a mixed phosphate concentrate containing rare earths.
According to the testing done by Nagrom, mot samples showed excellent phosphorus (P) solubility of over 40%, with one returning solubility of 81%.
DY6 shares rose on the news, and at 14:43 AEDT, they were trading at 6.5 cents – a rise of 3.17% since the market opened.
