Green Technology Metals Limited (ASX: GT1) (GT1 or the Company), a Canadian-focused multi-asset lithium business, is pleased to announce further high-grade lithium assay results from its 100%-owned Root Project, located approximately 200km west of its flagship Seymour Project in Ontario, Canada. Drilling at Root is initially focussed on the McCombe LCT pegmatite system, targeting rapid delineation of a maiden Mineral Resource estimate for this deposit.
HIGHLIGHTS
- Exceptional high-grade drill success at McCombe deposit, Root Project.
- Assays received for a further five holes from the Phase 1 diamond program including:
- RL-22-0013: 8.0m @ 1.72% Li2O from 64.0m (incl. 2.0m @ 4.06% Li2O from 64.6m)
- RL-22-0014: 8.4m @ 1.32% Li2O from 102.0m (incl. 1.0m @ 3.91% Li2O from 103.6m)
- RL-22-0015: 13.4m @ 1.24% Li2O from 28.9m (incl. 1.0m @ 3.16% Li2O from 29.3m)
- RL-22-0016A: 6.3m @ 1.52% Li2O from 66.3m (incl. 1.0m @ 2.38% Li2O from 70.7m)
- 31 holes have been drilled to date at McCombe with two diamond drill rigs operating 24/7
- Phase 1 definition drilling completed for 22 holes, assays pending for 8 holes
- Phase 2 extensional drilling in progress with strong visual spodumene logged in pegmatite intercepts; 9 holes completed, assays pending
- McCombe potentially joining with the Morrison pegmatite system to form a structure over several kilometres long
- Grab sample from new spodumene outcrop discovery at Root Bay prospect assayed 2.39% Li2O
- GT1 opting to begin environmental baseline surveys and permitting process
- Maiden Root Mineral Resource estimate on track for Q1 2023
“Recent assay returns have confirmed that McCombe is higher grade than originally interpreted based on historical data. The Root Project as a whole is also developing into a much larger complex, with McCombe potentially joining with Morrison to form a structure over several kilometres long, and recent spodumene discoveries at Root Bay confirming it extends east and west along a magnetic high.”
- GT1 Chief Executive Officer, Luke Cox
McCombe Deposit (Root Project)
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. Phase 1 and Phase 2 drilling by GT1 has now demonstrated McCombe to be a much simpler mineralised system: one major pegmatite averaging 10m thickness (ranging 2m to 19m), striking east-west with shallow dip approximately 30 degrees to the south, and a second pegmatite striking northeast with similar thickness.
The average grades, spodumene crystal size and crystal mass returned in the recent drilling at McCombe correlate well with the historic down dip continuity drill hole completed in 2016, which intercepted 67m @ 1.75% Li2O (see GT1 ASX release dated 8 November 2021, Prospectus). A second similar pegmatite has been intersected at the mid-point of the main pegmatite striking northeast and dipping to the southeast, with further targeted drilling set to extend this pegmatite to its natural limits.
Phase 1 drilling at McCombe has been completed, comprised of twenty-two (22) resource definition diamond holes. Assays have been returned for fourteen (14) holes all intersected thick and continuous high grade spodumene pegmatites from surface (refer to ASX announcement: All holes have intersected spodumene bearing pegmatite, 28 October 2022) with the recent holes returning the highest-grade intercept to date, 2m @ 4.06% Li20 (RL-22-0013) within a broader 8m pegmatite intercept averaging 1.72% Li20 from 64m downhole. Assays are still pending for the last eight (8) holes (see Figures 1 and 2) and are expected to be received in the coming weeks.
