Green Technology Metals Ltd (ASX:GT1)’s latest assay results from the Root Bay deposit at its 100% owned Root Project, point toward an exceptional high grades lithium deposit.
Root Bay is approximately 200 kilometres west of GTI’s flagship Seymour Project in Ontario, Canada.
The latest assays at Root Bay continue to demonstrate the consistency of high-grade mineralisation across the Root Bay deposit. Assays include:
- RB-23-1013:17.1m@ 1.77%Li2Ofrom71.0m
- RB-23-1014: 17.2m @ 1.74% Li20 from 57.2m
- RB-23-1009: 19.6m @ 1.50% Li20 from 26.9m
- RB-23-1038: 16.0m @ 1.78% Li20 from 167.1m
- RB-23-1020: 16.8m @ 1.69% Li20 from 82.5m
- RB-23-1032: 16.8m @ 1.61% Li20 from 139.6m
- RB-23-1025:16.3m@ 1.62%Li20 from131.4m
Root Lithium Project exploration target area.
Three phase program designed to elevate confidence
The Root Project currently has an Inferred Mineral Resource estimate of 12.6Mt @ 1.21% Li2O1 from its advanced prospect areas McCombe and Root Bay.
The project is made up of a series of pegmatite deposits at various stages of exploration development.
Currently, a comprehensive three-phase field exploration plan is being rolled out across the Western Hub. Simultaneously, a diamond drilling operation has been launched at the Root Lithium project. The purpose of this campaign is two-fold: to elevate the confidence in the maiden resource estimate of 12.6Mt @ 1.21% Li2O and to spot new high-priority drill targets. The immediate focus is on the sectors 1.5 kilometres east and 1.4 kilometres west of the present drilling at Root Bay.
The three phases consist of:
- Phase 1: Infill and east, west extensional drilling at Root Bay. Field exploration east and west of Root Bay, North Root tenement area and Allison Lake.
- Phase 2: Regional field exploration expanded to Pennock and Trist
- Phase 3: Exploration drilling from defined priority drill targets
GTI received initial assay results for the first nine holes at Root Bay for 1,183 metres as part of the initial 22,000 metres infill diamond drilling program designed to upgrade the Mineral Resource Estimate confidence from the inferred to indicated at Root Bay.
To date 45 holes for 7,668 metres have been completed with assays from 36 holes pending.

Significant diamond drilling assays from the infill diamond drill program at the Root Bay prospect.
These preliminary results confirm the central mineralisation tenor and continued high grades of up to 1.78% through the ore body.
Drilling also supports the current geological interpretation with some movement north and south around the flanks of the pegmatites.
Interestingly, the easterly extension of pegmatite RB-13 has increased the Root Bay trend extent another 150 metres to the east. Deeper drilling around the western pegmatite RB006 will also test potential depth extents around this thick and high-grade pegmatite.
What’s next?
GTI has completed 45 holes for 7,668 metres from the planned 22,000 metre program with assays pending for 36 holes.
Two drill rigs will continue their work until the program target is met at Root Bay, which is expected to occur by the end of August 2023.
Once the program is complete, GT1 intends to begin extensional drilling along a highly prospective, untested 3-kilometre extension of the Root Bay deposit including the new discovery at Root Bay West.
Note that prospecting is also continuing on areas to the east and west of Root Bay where the thin layer of overburden allows pegmatites to be easily identified.
On 26 June, GTI had immediate success with a new spodumene discovery 1.4 kilometres along strike and west of the Root Bay Deposit, extending the mineralised trend to over 2.7 kilometres. The mineralised outcrop matches the pegmatites defined at the Root Bay deposit and is likely part of a large stacked system of mineralised pegmatites.
GT1 is looking for new discoveries east and west of the highly prospective Root Bay prospect, where the company recently produced a maiden resource estimate of 8.1 million tonnes at 1.32% lithium.
Drilling will continue over the next quarter to upgrade the tonnage and JORC confidence level of the above maiden inferred mineral resource estimate.
