Independent Report - Significant Intercept In The Primary Points to Resource Upside at Cummins Range


Dr Chris Baker November, 2021 (Bridge Street Capital)


REE has just reported 4 new intercepts at Cummins Range, and all have wide (22 to 102m) potentially economic (1.6 to 3.1% TREO) intercepts. All are rich in the highly prized rare earth pair Nd and Pr.

These are important holes. This is the first confirmatory evidence that CR REO mineralisation extends beneath the weathered zone.


Not only is this one of the highest grade intercepts ever obtained at CR, mineralisation is hosted in the fresh rock (or “primary”). An earlier hole (hole 7) was part in oxide part fresh, but also with potentially an economic intercept (35m at 1.3%), which was starting to make us think that the exploration model applied by past explorers just wasn’t right. There has been an assumption that rare earths were concentrated in the oxide by a weathering process (so called deflation or some might have thought supergene enrichment. The deflation model is the implied source of very rich REO mineralisation at LYC’s Mt Weld deposit). We note as well that the two important REO’s praseodymium (Pr) and neodymium (Nd), key ingredients in high intensity magnets for use in electric motors.

These have been particularly strong over recent months, in response to supply constraints out of China with the demise of their environmentally unfriendly ionic clay mines and out of Myanmar, where exports have stalled. ...
