Magnum Mining and Exploration has released an update on its ongoing rare earth exploration work in Brazil, confirming that drilling has restarted at the potential Palmares and Azimuth projects.
The latest operational news highlights efforts to accelerate both drilling and sample processing at the two sites, following a planned shutdown during the Brazilian Recess period.
At Palmares, the company completed 15 reverse circulation (RC) holes totaling 225 m at the high-grade near-surface Feirinha prospect.
Initial progress was slowed by rain, which restricted initial access to the drilling rig.
To improve drilling productivity at Palmares, Magnum Mining intends to move to 24-hour operations, with two RC drill rigs operating in alternating 12-hour shifts.
This expanded schedule aims to significantly increase the exploration rate.
The initial batch of samples from Feirinha Prospect has already been prepared and is ready to be sent for analysis, with results expected by the end of January.
Previous work at Feirinha returned trench samples grading up to 1.69% (16,884 parts per million) total rare earth oxides (TREO) and rock samples grading up to 1.31% TREO.
The two-rig RC drilling campaign at Feirinha is designed to test mineralization at or near surface, which could support a low-cost rare earth element (REE) discovery.
At the Azimuth project, 13 holes have been completed for a total of 155 m, with the average depth increasing from 5 m to 12 m.
Where visual soil characteristics suggested favorable horizons, consistent with clay layers regionally linked to REE mineralization, drilling was continued to greater depths.
Work at Azimuth has focused on the priority Piracanjuba prospect, where the current drilling program has already been completed.
The first batch of samples was delivered to the ALS laboratory for analysis and analytical results are also expected by the end of January.
Drilling activity at Azimuth is expected to accelerate in line with plans to mobilize a second drill rig and begin full-time operations.
