GTI has announced very high spodumene concentrate recoveries from its Seymour Project, located approximately 250km north of Thunder Bay in Ontario, Canada. The spodumene concentrate represents a critical milestone for the business and future off-take partners.  

Four composite samples totalling approximately 1000kg of recent and historic diamond core, derived from the Seymour pegmatite was selected, and shipped for testing. The samples represent the different mineralisation phases seen in the pegmatite within, what GT1 expect to be, the final open pit mine shell at Seymour. 

Heavy liquid separation (HLS) test work was undertaken at SGS Canada’s facilities in Lakefield, Ontario. SGS compiled a master composite, based on the four samples selected, to provide a preliminary indication of the lithium beneficiation performance by utilising dense media separation (DMS).  

The Seymour bulk sample permit has been approved by the Ontario Mines Department (MNDM) and sampling is planned to begin in January 2023 where we will be extracting approximately ninety-nine tonnes from the North Aubry pegmatite outcrop within the Seymour project. The spodumene concentrate produced through the pilot work will be used as feed stock for the Lithium Hydroxide Conversion Program (LHCP), all forming part of the ongoing feasibility study. 

“The next few months will be an exciting time for the team at GT1 as we focus on increasing the value of our Flagship Seymour Project through metallurgical test work. These results will culminate part of our Preliminary Economic Assessment (PEA) and marks another important step closer to building a vertically integrated lithium business in Ontario, Canada.”

Another strong announcement from GT1, with their highest grade drill intercept to date at the Root Project. 31 holes have been drilled to date at the McCombe deposit with two diamond drill rigs operating 24/7. Phase 1 definition drilling has been completed for 22 holes, with assays pending for 8 holes. Phase 2 extensional drilling is currently in progress with strong visual spodumene logged in pegmatite intercepts; 9 holes have been completed, assays pending. The Maiden Root Mineral Resource estimate is 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 is up 8% this morning, after announcing a new discovery at its flagship Seymour Lithium Project in Ontario, Canada. The new discovery, Blue Bear, is located approximately 500m south-east of the Aubry Complex, on the Pye West Limb, and sits within the same current mine permitting and baseline study boundary. Fourteen diamond holes have been drilled to date, all intersecting pegmatite, with Six holes have returned assays to date. Ongoing diamond drilling and channel sampling now rapidly delineating the Blue Bear deposit.

GT1 has had a massive run over the last few months, up over 50%.

“This is the first discovery at Seymour in over 50 years. To find a spodumene-bearing pegmatite under cover utilising classic geological and modern geophysical and geochemical techniques is testament to the abilities of the GT1 technical team and our exploration modelling.”

“We will now drive hard to rapidly delineate the scale of this new discovery, as well as testing further new targets in this area of North Seymour. This is expected to culminate in an updated Mineral Resource estimate for the Seymour Project in coming months. We also continue to rapidly progress Preliminary Economic Assessment work on a development of Seymour, with scheduled completion in Q1 2023.” - GT1 Chief Executive Officer, Luke Cox 

GT1 has announced inaugural assay results from its 100%-owned Root Project (McCombe Deposit), located approximately 200 km west of GT1’s flagship Seymour Project. Drilling is initially focussed on the McCombe LCT pegmatite system to delineate a maiden Mineral Resource. 

Inaugural Phase 1 diamond drilling at McCombe (Root Project) has intersected thick and continuous high grade spodumene pegmatites from surface

Assays have been received for the first 9 holes from the Phase 1 diamond drilling including:

• RL-22-001 for 12.4m @ 1.77% Li2O from 11.8m
• RL-22-002 for 15.3m @ 1.20% Li2O from 42.2m (incl. 10.8 @ 1.65% Li2O)
• RL-22-003 for 11.5m @ 2.03% Li2O from 72.0m
• RL-22-006 for 9.5m @ 1.54% Li2O from 21.7m
• RL-22-007 for 9.8m @ 1.51% Li2O from 64.9m (incl. 8.0m @ 1.81% Li2O)
• RL-22-008 for 8.8m @ 1.80% Li2O from 71.5m (incl. 8.0m @ 1.94% Li2O) 

“Because Root hasn’t been properly explored since 1950, substantial opportunity exists to undertake systematic and modern exploration of this tenure. These initial assay results and intercept thicknesses from McCombe are outstanding, and together with mapping of new untested pegmatites, clearly justify the ramping up of our drilling and broader activities at Root over the coming months.”

- GT1 Chief Executive Officer, Luke Cox

GT1 has started initial drilling at McCombe with 22 holes for 2,500m, which is targeting to confirm historical drilling and sampling. Historical drilling demonstrated down-dip continuity at McCombe and this included 67m @ 1.75% Li20.

The second phase of drilling will target significant expansion of the known McCombe mineralisation, with a total of 24,000m diamond drilling program initially planned over McCombe and Morrison pegmatites.

The drilling at McCombe is called the Root Project and it is located approximately 200 km west-north-west of GT1’s Seymour Project. Drilling will also continue at parallel at Seymour, with two drill rigs operating.

“Commencing drilling at Root is another significant milestone for our business. The initial focus at the advanced McCombe LCT pegmatite is confirmation and extension of known mineralisation, followed by rapid estimation of a maiden Mineral Resource estimate. We then plan to target other known spodumene-bearing LCT pegmatites at Root, including Morrison and Root Bay.”
