Latin Resources has secured new tenure that doubles the strike length of its Colina lithium prospect to 2km after drilling intersected thick, high-grade near surface pegmatites.

The new option agreement extends the company’s wholly-owned tenure in Brazil by a further 1.2km to the south where the known high-grade lithium pegmatites are interpreted to continue under shallow cover.

Latin Resources (ASX:LRS) is understandably keen to discover just how far the pegmatites at Colina stretch for given that its southernmost drillhole (SADD006) – located close to the new tenure – returned a 21.1m intersection grading 1.2% lithium oxide.

With the new tenure in place, the company is likely to expand the current 100-hole resource definition drilling campaign totalling about 25,000m currently underway at the prospect to include step-out drilling to the south to outline the full strike extent of the identified pegmatites and deeper holes to test for stacked pegmatites.

Building on existing finds

Recent deeper drilling had indicated the potential for Colina to host deeper stacked pegmatites after observing between 15% and 20% visual spodumene in a 7.46m pegmatite intersection from a depth of 207.0m in hole SADD020.

Three diamond rigs have drilled 25 holes totalling 4,800m to date with a fourth rig arriving on site later this month to accelerate the resource drilling campaign.

“We are very pleased to be able to secure this additional ground to the south of our Colina prospect, where drilling shows that our high-grade pegmatites are open and continue to the south in this direction,” exploration manager Tony Greenaway said.

“Our resource definition drilling is progressing well and is on schedule to meet our fast-tracked timeline. We have additional drilling rigs on site now and have expanded our geological team on site to keep pace with the increase in activity.”

Metallurgical testing underway

Latin has also confirmed that SGS laboratory in Brazil has started preliminary test work on the Colina lithium pegmatite.

This work will include dense media separation and flotation testing to determine lithium recovery into final concentrates, and detailed mineralogical and petrological studies to confirm individual miner species present in the Colina pegmatite.
