RESOURCE DEFINITION DRILLING CONTINUES TO SHOW EXCELLENT RESULTS FROM THE “COLINA PROSPECT”, BANANAL VALLEY, BRAZIL
LRS has provided an update in respect of resource definition drilling at the Company’s Colina Prospect which continues to return very encouraging results from detailed geological logging; as well as provide initial observations from drilling at the Company’s second target area, the Monte Alto Prospect.
Colina Prospect – Resource Definition Drilling
Extensive resource definition drilling is now well underway at the Company’s Colina Lithium Prospect in Brazil. The drilling campaign comprises an estimated 100 holes for approximately 22,000 - 25,000m, and will focus on a strike extent of 800m, where previous drilling has identified high-grade lithium bearing pegmatites.
As previously reported, the first hole of the resource drilling campaign SADD016 , has intersected a very wide 27.78 meters of coarse-grained fresh pegmatite, with geological logging identifying a core zone of 21.48 meters with a visual estimation of spodumene of over 20%. Logging of drill hole SADD017 , drilled immediately down dip from SADD016, has also confirmed a significant intersection of spodumene bearing pegmatite, further demonstrating the strong continuity of the pegmatites at the Colina Prospect.
Resource definition drilling is ongoing.
Monte Alto Prospect
Drilling of the first five holes at the Monte Alto Prospect has been completed. Logging of these holes has highlighted a moderate north-easterly plunge, not previously recognised in the weathered surface outcrop; with the initial three holes (MADD001 - MADD003) failing to intersect the targeted pegmatite zone at depth.
Following a re-examination of the outcropping pegmatite within the historic trenching and workings, combined with new structural information gained from drilling the next two holes (MADD004 and MADD005) , were relocated 100m and 200m to the north-east respectively, to test the projected down plunge extension of the pegmatite.
Logging has confirmed that both of these latest two holes (MADD004 and MADD005), have intersected pegmatite, however no material spodumene was logged in the core. This outcome has led to the interpretation that the Monte Alto pegmatites may represent a zoned heterogeneous pegmatite; an interpretation that is supported by the presence of some exotic minerals mapped in adjacent pegmatites in the Monte Alto area. Further drilling is required to fully understand the significant of these initial observations.
Drilling is ongoing at Monte Alto, with subsequent drilling focusing on an area where remapping of outcrop has confirmed the presence of large weathered spodumene crystals at surface.
