Recent developments in Brazil indicate progress for rare earth mining projects. Brazilian Rare Earths updated its resource estimate for the Monte Alto deposit, reporting a material increase in the indicated portion of its ultra-high-grade resource following a drilling campaign. The company is conducting further drilling and expects to complete a concentrate sales study by the end of the year.

Separately, Rare Earths Americas reported a 48% relative improvement in rare earth element leach recovery during laboratory tests at its Alpha Project in Bahia. Tests conducted by SGS achieved a recovery rate of approximately 40% for certain rare earth elements, compared to a previous assumption of 27%. While these results require confirmation through larger-scale testing, the improvement could enhance the economic viability of the project, which contains estimated inferred mineral resources of 202 million tonnes.
