- Results continue to increase GT1’s confidence in the potential for resource expansion at Root
- Pegmatites RB006 and RB007 demonstrate strong continuity to over 1200m downdip from surface
- Assays for eight holes are pending, due to be received mid-February 2025
Special Report: Green Technology Metals has made a solid start to 2025 with thick, high-grade results increasing confidence in the potential for resource expansion at the Root Bay lithium deposit in Ontario.
Drilling officially wrapped up in December 2024 with a total of 14 drillholes for 9132m, targeting mineralisation depth extension below the existing 14.6Mt resource at 1.21% Li20.
The program intersected multiple wide zones of lithium-caesium-tantalum (LCT) pegmatites, defining the main two pegmatites (RB006 and RB007) and extending their interpretation a further 450m below the resource and over 700m below a US$950 pit design.
Stand-out results include 17.6m at 1.44% Li20 from 509.7m, 9.1m at 1.57% from 476.4m and 11.7m at 1.32% from 623.2m.
Green Technology Metals (ASX:GT1) will use the results to enhance its geological understanding of the Root deposit and advance studies for potential future underground operations.
They will also bolster GT1’s mission of becoming Ontario’s first integrated lithium producer, a goal that attracted an $8m investment at a premium from South Korean electric vehicle battery metals producer EcoPro Innovations in August last year.
Updated resource around the corner
The company is planning to build a lithium conversion facility in Thunder Bay near the sites of its proposed Seymour and Root hard rock lithium mines as a part of its Ontario integrated lithium strategy.
A joint pre-feasibility study (PFS) leveraging EcoPro’s in-house research and development capabilities is currently underway.
GT1 managing director Cameron Henry said the drilling campaign was completed on schedule and forms part of the company’s flow-through spend commitments at the Root Bay deposit, part of the Root lithium project.
“These latest results underscore the potential of the asset as a reliable long-term feed source for our proposed lithium conversion facility in Thunder Bay,” he said.
“We eagerly anticipate the final bath of assay results and look forward to delivering an updated resource, which will play a key role in supporting our underground optimisation studies – a major focus for us over the past year.”
Remaining assays
To date, GT1 has defined the main pegmatites over 1200m downdip from surface and up to 700m below surface.
Assays for eight holes remain pending and are due to be received by mid-February.
Once the final assays are returned, the company plans to update the resource to incorporate these deeper drill holes and initiate further integrated open pit and underground mining study work to further optimise the mineral resource.
