Latin Resources says it’s on track to release a maiden mineral resource estimate (MRE) after receiving the final assay results from resource drilling at the Colina lithium prospect in Brazil.

The drilling returned high-grade intersections, including:

  • 10.91m at 1.52 %Li2O;
  • 8.19m at 1.61 %Li2O;
  • 25.00m at 1.47 %Li2O;
  • 7.41m at 1.61 %Li2O;
  • 8.70m at 2.16 %Li2O;
  • 10.23m at 1.59 %Li2O; and
  • 5.80m at 1.82%Li2O.

With the addition of these final assays, Latin Resources (ASX:LRS) says the MRE for the prospect is on schedule to be delivered in December 2022.

“The company’s maiden JORC Mineral Resource Estimate is on track to be delivered in December after incorporating these final results which continue to showcase the consistent nature of the pegmatite mineralisation at Colina,” exploration manager Tony Greenaway said.

PEA and metallurgical studies underway 

Greenaway said with MRE drilling completed at Colina, the rigs can shift their focus to the recently discovered Colina West pegmatites “with the aim of incorporating this second area into the PEA and other studies that the company has underway.”

Latin has now commenced a series of metallurgical test work programs with the initial first pass sighter test work showing a high recovery of 78.72% of the Li2O into a concentrate grading a very high 6.57% Li2O.

Further sighter test work is underway to explore the optimal crush size, and additional heavy liquid separation (HLS) cut points, and fine fraction flotation in order to optimise the larger test work flowsheet for the planned detailed Preliminary Economic Assessment (PEA).
