ROOT PROJECT
The Root Project is located near the First Nation community of Slate Falls and approximately 300km northwest of Thunder Bay.
​
High Grade Inferred Mineral Resource Estimate (MRE) for the Root Lithium project (McCombe + Root Bay) is 12.6 million tonnes @ 1.21% Li2O and 62 ppm Ta2O5 incorporating an additional 8.1 million tonnes @ 1.32% Li20 from the Root Bay deposit to the reported 4.5 million tonnes @ 1.01% Li2O from the McCombe deposit. (See ASX Announcement 7/6/2023)
​
Significant potential for further Mineral Resource growth along strike and down dip at the McCombe Deposit, and across the larger Root project area.
Further diamond drilling will continue in parallel to the current programs running at Morrison and Root Bay
McCombe, Morrison and Root Bay now forming 20km corridor of prospective ground for further resource development and currently undergoing drill testing.
The Root project comprises several pegmatite deposits with varying degrees of exploration development and hosts a maiden Inferred Mineral Resource estimate of 4.5MT @ 1.01% Li2O1 from its most advanced prospect area McCombe, situated at the western end of the 20km long Project (Figure 1). McCombe, and the entire Root Project has significant potential for further Mineral Resource growth along strike and down dip and across the project area.
Initial exploration had focused on priority targets mainly at the McCombe prospect area, however drilling has now expanded to include priority targets at both the Morrison and Root Bay prospect areas which have returned successful results and indicated the Root project to be bigger than originally anticipated.

McCombe Deposit 2023 EXPLORATION PROGRAM
Drilling is currently paused at the Root project while the company commences a large-scale exploration program over the area in the upcoming field season to identify new priority drill targets. The focus for the field exploration program will be the northern tenement area of the Root project that has had no previous exploration to date and will include prospecting, mapping and sampling.
On re-commencement of GT1’s diamond drilling program, Root Bay will remain the primary focus for JORC Resource definition with further drilling planned on new priority targets as well as existing targets at McCombe, Morrison and Root Lake, focusing on increasing the Company’s current JORC Resource base of 14.4Mt @ 1.03% Li2O.
​
Seymour has an existing Mineral Resource estimate of 9.9 Mt @ 1.04% Li2O (comprised of 5.2 Mt at 1.29% Li2O Indicated and 4.7 Mt at 0.76% Li2O Inferred).1 and Root has an Inferred Mineral Resource Estimate of 4.5 Mt @ 1.01% Li20.

McCombe Deposit
​
The McCombe pegmatite has been classified as LCT-type, spodumene-subtype pegmatite based on its abundance of spodumene and highly evolved K-feldspar chemistry. The McCombe pegmatite consists of a cluster of dykes that outcrop on surface and strike east west to northeast-south-west and gently dip to the south to southeast.
The McCombe lithium deposit is currently the most advanced LCT pegmatite at the Root project and is located on the west side of the tenement package. The deposit has a total strike extent of approximately 1,500m and has been drilled to a down dip depth of over 250m.
Exploration at the Root project has initially focused on four target areas; McCombe, Morrison, Root Bay and Root Lake. However, a large area surrounding these targets remains underexplored and highly prospective for new LCT pegmatite target areas.
Maiden diamond drilling by GT1 commenced at the project only five months ago and initially focused on the McCombe deposit which has successfully generated a 4.5Mt maiden resource. Drilling has more recently expanded to include Morrison and Root Bay which has returned high-grade intercepts and demonstrated significant potential for ongoing resource expansion at the Root Lithium Project.
Root Bay
Prior to 2023 the Root Bay prospect was only identified as a small pegmatite outcrop showing finer-grained spodumene mineralisation, with no historical drill testing. Building on the success from the first three GT1 holes returned from Root Bay (announced on the 31 March 2023), the Company has expanded the diamond drill program to 35 holes totalling 8806 meters that has now been completed.
As shown on the cross section below, drilling is starting to reveal a multiple, shallow-dipping LCT pegmatite system up to 18m thick, with exceptional lithium grades up to 1.73% Li2O.
So far, 13 stacked pegmatites have been identified and defined to over 200m depth and 1,300m along the Root Bay trend, with a northerly strike length of up to 300m. The stacked pegmatites at Root Bay range in thickness from 2m to 17.8.
The pegmatites are hosted within an Archean package of meta-basalts. The meta-basalts are themselves sandwiched in a 300m wide corridor flanked in the south by meta-sediments and in the north by more meta-sediments hosting Banded Iron Formation units. The contacts between the meta-basalts and the meta-sedimentary units are thought to be steeply dipping to sub-vertical.
Morrison Prospect
The second drilling phase has been completed at Morrison for 32 holes and 5,400m, confirming the pegmatites strike up to 1.6km long trending east-west. The western most pegmatites at Morrison appear to be connected to the 4.5Mt McCombe deposit system.
​
At least two LCT pegmatites have been intersected at Morrison to date, with some encouraging intercepts up to 10m thick. Further delineation is being planned to identify potential higher grade pegmatite offshoots from the Morrison trend, similar in nature to McCombe and Root Bay. The Morrison Prospect remains open at depth.
2023 Exploration Program
Drilling is currently paused at the Root project while the company commences a large-scale exploration program over the area in the upcoming field season to identify new priority drill targets. The focus for the field exploration program will be the northern tenement area of the Root project that has had no previous exploration to date and will include prospecting, mapping and sampling.
​
On re-commencement of GT1’s diamond drilling program, Root Bay will remain the primary focus for JORC Resource definition with further drilling planned on new priority targets as well as existing targets at McCombe, Morrison and Root Lake, focusing on increasing the Company’s current JORC Resource base of 14.4Mt @ 1.03% Li2O .
