Li-FT Power Hits 1.65% Lithium at BIG East With Mineralisation Open at Depth
Li-FT Power confirms lithium mineralisation at Yellowknife with latest drill results
Li-FT Power has reported assay results from 20 diamond drill holes totalling 5,324 m at the Yellowknife Lithium Project in Canada’s Northwest Territories. This includes 17 holes (4,778 m) from the 2026 winter programme and 3 holes (546 m) from the 2025 summer programme. The results mark the first drill campaign at the BIG pegmatite area since the company published an inferred mineral resource estimate in October 2024. The project is located outside Yellowknife city with existing road access via Ingraham Trail, and proximity to the Talston hydroelectric power station.

Headline intercepts from the drill programme
The company has reported five highlight intercepts spanning three pegmatite targets: BIG East, Fi Main, and Ki. Grades range from 1.09% to 1.41% Li₂O across widths of 17 m to 26 m.
| Hole ID | Target | Intercept | Li₂O Grade |
|---|---|---|---|
| YLP-0304 | Fi Main | 21 m (incl. 13 m) | 1.09% (incl. 1.38%) |
| YLP-0306 | Ki | 18 m | 1.41% |
| YLP-0312 | BIG East | 26 m (incl. 17 m) | 1.29% (incl. 1.65%) |
| YLP-0315 | BIG East | 22 m | 1.09% |
| YLP-0320 | BIG East | 17 m | 1.32% |
Consistent intercepts above 1% Li₂O across multiple targets demonstrate the mineralised system’s scale and grade potential, providing data to potentially expand or upgrade the existing resource base.
What is Li₂O and why does lithium grade matter?
Li₂O (lithium oxide) is the standard measure for reporting lithium grades in hard rock deposits. Spodumene is the lithium-bearing mineral in these pegmatites. Grades above 1% Li₂O are generally considered economically attractive for hard rock lithium projects. Higher grades typically translate to lower processing costs per unit of lithium produced, which directly impacts project economics. Understanding these grade benchmarks helps investors assess whether reported results are commercially meaningful.
BIG pegmatite drilling extends known mineralisation
Sixteen of the 17 winter 2026 holes targeted BIG East, with one hole at BIG North. BIG East is a 1.8 km strike length corridor of parallel-trending dykes, 10-100 m wide, dipping 55°-75° west. Drilling extended along 1,000 m of strike length and reached depths of 50 to 300 m below surface.
Key results confirming mineralisation remains open at depth and to the south include:
- YLP-0320 (most southerly hole): 17 m at 1.32% Li₂O at 200 m depth
- YLP-0312 (central BIG East): 26 m at 1.29% Li₂O, including 17 m at 1.65% Li₂O
- YLP-0315: 22 m at 1.09% Li₂O
Some deeper holes (YLP-0317, YLP-0316, YLP-0308) intersected pegmatite with negligible spodumene, indicating grade variability at depth. Open mineralisation to the south and at depth provides exploration upside beyond the current resource footprint.
Fi Main and Ki pegmatites deliver geotechnical and grade data
The three 2025 summer holes (Fi Main, Fi SW, Ki) were drilled for geotechnical strength testing, with assays completed post-testing. Results were:
- Fi Main (YLP-0304): 21 m at 1.09% Li₂O (incl. 13 m at 1.38% Li₂O)
- Fi SW (YLP-0305): 21 m at 0.50% Li₂O (incl. 8 m at 1.10% Li₂O)
- Ki (YLP-0306): 18 m at 1.41% Li₂O
Fi Main extends over 1.5 km strike length whilst Ki extends over 1.3 km strike length. Geotechnical data supports future mine planning studies, whilst assays confirm continued grade consistency at these satellite targets.
Yellowknife Lithium Project’s infrastructure advantage
Location and access
The project is located outside Yellowknife city with road access via Ingraham Trail. Infrastructure proximity includes the Talston hydroelectric power station, Yellowknife airport, and the Tibbitt to Contwoyto winter road system servicing established diamond mines (Ekati, Diavik, Gahcho Kué). The project is 480 km by truck from existing operations.
Permit and development pathway
The company published an inferred mineral resource estimate in October 2024 (TSXV) / May 2026 (ASX Prospectus). Ongoing drilling and exploration work continues across the project area.
Infrastructure proximity reduces future capital expenditure risk and supports a potentially lower-cost development pathway compared to remote greenfield lithium projects. This positions the asset favourably within the hard rock lithium development pipeline.

What comes next for Li-FT Power
The company is continuing drilling and exploration activities across the Yellowknife Lithium Project. Results from this programme will inform potential resource updates or expansions. Li-FT also holds the Adina Lithium Project in Quebec’s James Bay region, providing geographic diversification across two Canadian jurisdictions. Ongoing drilling provides a catalyst pipeline for newsflow, whilst dual-jurisdiction exposure reduces single-project concentration risk.
