Latin Resources has hailed definition drilling at its Colina prospect in Brazil as producing encouraging results. The company says the work, part of the larger Bananal lithium project in Brazil, continues to underline the operations potential, with recent logging confirming the down-dip continuation and expansion of previously identified high-grade lithium pegmatites.
Management believes the operation could produce a significant new discovery, with recent work in the area throwing up some great results, including a rock chip sample that ran a respectable 3.22 per cent lithium oxide.
Latin’s recent work comes after a two-hole probe at Colina that intersected a set of broad pegmatites intersections, including one more than 27m wide.
The company says the 27m pegmatite had a high-grade spodumene component that swept across a 21m zone. Spodumene is seen as an important source of lithium and is known to host high-grade concentrations of up to 8 per cent lithium oxide.
In what also bodes well for the projects outlook, the 21m inclusion was comprised of moderately weathered, coarse-grained pegmatite with fresh elongated spodumene crystals — all ingredients that could add up to a wholesome lithium resource at Colina.
Latin is now part way through a 100-hole, 22,000m-plus resource definition play at the project. With recent logging indicating the pegmatites are not only continuing but getting wider, the early signs point to a victory in the company’s Brazilian battery metals hunt.
The work follows on from the discovery of several lithium-rich pegmatites that ran up to 800m in strike length.
Latin has also completed a five-hole perforation at the proximal Monte Alto prospect.
The opening three holes at the target were intended to test for outcropping pegmatite that had been observed at superficial levels, however they were unable to intersect the targeted pegmatite zone at depth.
Subsequent logging did confirm that the final two holes intersected pegmatite but no spodumene material was found.
The result has led to the hypothesis that the pegmatites at Monte Alto are a zoned heterogeneous type, that is backed up by the presence of various exotic minerals mapped in nearby pegmatites in the contiguous area.
Drilling at Monte Alto is continuing, with the next phase set to vector in on a region where remapping of the outcrop revealed big weathered spodumene crystals.
The latest results could prove a real shot in the arm as Latin works toward a late 2022 maiden resource estimate.
