Li-FT Power Hits 26m at 1.29% Lithium and Extends BIG East Open at Depth
Li-FT Power delivers strong drill results from Yellowknife Lithium Project
Li-FT Power (ASX: LFT) has reported drill results from 20 holes totalling 5,324 metres at its Yellowknife Lithium Project in Canada’s Northwest Territories. This comprises 17 holes (4,778 m) from the 2026 winter program and 3 holes (546 m) from the 2025 summer program. This marks the first drilling at BIG since publication of the inferred mineral resource in October 2024 (TSXV) and 22 May 2026 (ASX).
The results provide fresh data on project continuity and grade confirmation following the mineral resource estimate. The winter campaign targeted the BIG area (BIG East and BIG North), while the 2025 summer program targeted the Fi Main, Fi SW, and Ki pegmatites, with drilling extending mineralisation both along strike and at depth.

Standout intercepts confirm high-grade lithium mineralisation
The drill programme returned significant lithium grades across multiple pegmatite targets, with results consistent with or exceeding the grades supporting the existing resource estimate. High-grade intercepts were recorded at BIG East, Fi Main, and Ki pegmatites, validating the project’s lithium endowment.
| Hole ID | Target | Interval | Li2O Grade | Includes |
|---|---|---|---|---|
| YLP-0304 | Fi Main | 21m | 1.09% | 13m at 1.38% |
| YLP-0306 | Ki | 18m | 1.41% | – |
| YLP-0312 | BIG East | 26m | 1.29% | 17m at 1.65% |
| YLP-0315 | BIG East | 22m | 1.09% | – |
| YLP-0320 | BIG East | 17m | 1.32% | – |
The consistency of these grades across the drilling envelope confirms the geological continuity of lithium mineralisation within the pegmatite systems. The higher-grade zones identified support the potential for resource expansion in future drilling campaigns.
What is spodumene and why does grade matter?
For investors new to hard rock lithium projects, understanding the reporting metrics is essential:
- Spodumene is a lithium-bearing mineral and the primary host for lithium at Yellowknife
- Li2O (lithium oxide) is the standard reporting metric for hard rock lithium deposits
- Grades above 1.0% Li2O are generally considered high-grade for spodumene deposits
- Thicker intercepts at high grades support potential open-pit economics and resource expansion opportunities
The combination of grade and width determines the economic viability of a lithium deposit. Wide intersections at grades exceeding 1.0% Li2O indicate robust mineralisation that may support lower-cost mining operations.
BIG East drilling extends mineralisation at depth and along strike
Sixteen of the 17 winter holes targeted BIG East, testing the pegmatite corridor to depths of 50-300 metres below surface. Drilling extended along 1,000 metres of strike length. YLP-0320 returned 17m at 1.32% Li2O and leaves the system open to the south and at depth. YLP-0312 intersected 26m at 1.29% Li2O including 17m at 1.65% Li2O.
The BIG East drilling campaign focused on extending known mineralisation beyond the existing drill envelope. Results confirmed pegmatite continuity across multiple drill sections, with several holes intersecting thick zones of spodumene-bearing pegmatite at depth.
Mineralisation remains open
Results confirm mineralisation extends beyond existing drilling. The BIG East pegmatite complex extends for at least 1.8 km of strike length, ranges 10-100m wide, and dips 55-75 degrees west. Open mineralisation at both southern and depth extents indicates potential for resource growth in future drilling campaigns.
The most southerly drill section (YLP-0319 and YLP-0320) returned significant grades, with YLP-0320 intersecting spodumene mineralisation 200 metres below surface. This confirms the pegmatite system remains mineralised well below the current resource envelope, presenting a clear target for follow-up drilling.
Geotechnical drilling supports feasibility work at Fi Main and Ki
The three 2025 summer holes at Fi Main, Fi SW, and Ki pegmatites were drilled for geotechnical strength testing. These holes also returned assay results after testing. YLP-0304 at Fi Main returned 21m at 1.09% Li2O including 13m at 1.38% Li2O. YLP-0306 at Ki returned 18m at 1.41% Li2O.
Geotechnical testing is a precursor to feasibility studies, providing data on rock strength and structural characteristics required for mine design. Strong grades from these holes provide dual value: confirming mineralisation while advancing engineering work. The results demonstrate that geotechnical drilling programmes can deliver both technical and geological data, supporting project advancement on multiple fronts.
Strategic location supports development pathway
Yellowknife Lithium Project is located outside the city of Yellowknife with established infrastructure. Infrastructure access reduces capital requirements and de-risks project development compared to remote greenfield sites.
Key advantages include:
- Road access via the Ingraham Trail and winter road network
- Hydroelectric power from the Talston Hydro facility with existing transmission lines
- Airport proximity supporting personnel and equipment transport
Li-FT also holds the Adina Lithium Project in Quebec and early-stage exploration properties in both jurisdictions. The combination of infrastructure proximity and established mining services positions Yellowknife Lithium Project favourably within the Canadian lithium development landscape.

What comes next for Li-FT Power
The Company is engaged in ongoing drilling and exploration work on the properties. All holes were drilled perpendicular to dyke orientation with true widths estimated at 65-100% of drilled widths for winter holes and 50-90% for summer geotechnical holes. The mineral resource estimate was released in October 2024 (TSXV) and announced on ASX on 22 May 2026.
Continued drilling signals management commitment to advancing the project toward development milestones. The combination of resource definition drilling at BIG East and geotechnical drilling at Fi Main and Ki demonstrates a dual strategy: expanding the resource base while simultaneously advancing engineering studies required for feasibility work.
