Green Technology Metals Limited (ASX: GT1) has obtained further high-grade lithium assay results returned from its 100%-owned Root Project, located approximately 200km west of the flagship Seymour Project in Ontario, Canada.
Drilling at Root was initially focussed on the McCombe LCT pegmatite system, targeting rapid delineation of a maiden Mineral Resource Estimate, exploration has now been expanded to the Morrison prospect, situated one km east.
An aggressive drill programme is actively underway with two drill rigs working day and night shifts at the Root Project.
“Morrison is the second target on the Root Project that hosts multiple lithium bearing pegmatites and it’s great news to receive a near surface 10m wide Spodumene intercept from the very first hole,” GT1 CEO, Luke Cox, said.
The McCombe LCT (Lithium-Caesium-Tantalum) pegmatite is currently the most advanced prospect at the Root Project. Historical drilling completed by previous owners from 1950 to 2016 intersected numerous pegmatites, generally dipping to the south and striking east-west. Drilling by GT1 has now demonstrated McCombe to be a simpler mineralized system consisting of:
▪ one major pegmatite averaging 10m true thickness (ranging 2.0m to 19m), striking east-west with shallow dip approximately 30 degrees to the south, open along strike and down dip
▪ all pegmatites appear to be connected and truncate against each other, forming a swarm
▪ there are several drill intersections that haven’t been assigned to a pegmatite (wireframe) allowing further potential for additional pegmatite discoveries within the system.
Phase 1 drilling at McCombe has been completed, comprising of 22 resource definition diamond holes with assays returned for all holes intersecting thick and continuous high grade spodumene pegmatites from surface. The Phase 1 drilling has delineated, extended, and simplified the historical mineralized pegmatites in all directions, Phase 2 drilling now underway will continue to explore the pegmatites along strike and down dip in the coming weeks for incorporation into the maiden Mineral Resource Estimate.
The Morrison LCT spodumene pegmatites are located approximately one km east of McCombe and were explored in the mid to late 1950’s. The pegmatites strike east west and dip about 30 degrees towards the south. Outcrop of the pegmatite is approximately 200m long and tested by trenching, but historical drilling has also proven the strike of the pegmatite to be at least 1.6km to the west with additional occurrences to the north.
Initial drilling at Morrison comprising of 20 holes for 2,500m is targeted to confirm historical drilling and sampling. Thirteen diamond holes have intersected pegmatites with the maiden drill hole RL-22-0364 returning 10.6m @1.25% Li2O from 54.0m (incl. 8.0m @1.62% Li2O from 55.0m). Drilling is continuing on a 24-hour basis with core samples being regularly transported to Thunder Bay for assaying.
The second phase of drilling at Morrison will then be designed to test for extensions of the mineralized pegmatites in all directions, infill key sections and rapidly facilitate delineation of a Mineral Resource estimate.
