Li-FT Power Hits 26m at 1.29% Lithium and Extends BIG East System at Depth
Li-FT Power delivers strong lithium intercepts from Yellowknife drilling campaign
Li-FT Power has completed 20 drill holes totalling 5,324 metres across its Yellowknife Lithium Project in Canada’s Northwest Territories. The campaign comprises results from both the 2026 winter programme (17 holes, 4,778 m) and the 2025 summer programme (3 holes, 546 m), marking the first drilling at the BIG area since the company released its inferred mineral resource in October 2024 (TSXV) and 22 May 2026 (ASX). The project benefits from strategic infrastructure positioning near Yellowknife, including road access and an operational airport.

Standout drill intercepts across multiple pegmatite targets
The campaign delivered five headline intercepts spanning multiple pegmatite systems—Fi Main, Ki, and BIG East—demonstrating mineralisation across the broader project area. The results include high-grade intervals within broader mineralised zones, with grades consistently above 1% Li₂O.
| Hole ID | Pegmatite | Interval | Li₂O Grade | Including |
|---|---|---|---|---|
| YLP-0304 | Fi Main | 21 m | 1.09% | 13 m at 1.38% |
| YLP-0306 | Ki | 18 m | 1.41% | — |
| YLP-0312 | BIG East | 26 m | 1.29% | 17 m at 1.65% |
| YLP-0315 | BIG East | 22 m | 1.09% | — |
| YLP-0320 | BIG East | 17 m | 1.32% | — |
These consistent grades above 1% Li₂O across multiple targets support the thesis of a substantial mineralised system with potential for resource expansion.
Understanding lithium pegmatite grades
Li₂O percentages represent the concentration of lithium oxide in drill core samples. Spodumene is the lithium-bearing mineral being targeted at Yellowknife, confirmed through visual core logging, mineralogical studies, and metallurgical work. Grades above 1% Li₂O are considered strong for hard rock lithium deposits, indicating economically viable mineralisation.
True widths of intercepts range from 65-100% of drilled widths for winter 2026 holes (drilled perpendicular to dyke orientation) and 50-90% for summer 2025 geotechnical holes (drilled slightly oblique to the pegmatite bodies). Understanding this distinction helps investors interpret drill intercepts in the context of lithium project development, as drillholes rarely intersect mineralisation at exact right angles.
BIG East pegmatite shows depth and strike extension potential
BIG East formed the primary target of the 2026 winter programme, with 16 of 17 holes concentrated on this system. The pegmatite complex comprises a north-northeast trending corridor exposed for at least 1.8 km of strike length, ranging from 10-100 m wide, and dipping 55-75° west. The drilling tested depths of 50 to 300 metres below surface and extended along 1,000 m of strike length.
YLP-0319 and YLP-0320 represent the most southerly holes drilled on BIG East. YLP-0320 returned 17 m at 1.32% Li₂O at 200 m below surface, while YLP-0319 intersected 11 m at 1.22% Li₂O at 100 m below surface. The system remains open to the south and at depth, suggesting resource growth potential beyond the existing inferred estimate. YLP-0312 delivered the best interval: 26 m at 1.29% Li₂O including 17 m at 1.65% Li₂O, testing 175 m below surface.
Key BIG East intercepts include:
- YLP-0312: 26 m at 1.29% Li₂O (incl. 17 m at 1.65%)
- YLP-0315: 22 m at 1.09% Li₂O
- YLP-0320: 17 m at 1.32% Li₂O
- YLP-0319: 11 m at 1.22% Li₂O
- YLP-0313: 10 m at 1.12% Li₂O plus 10 m at 0.68% Li₂O (incl. 6 m at 1.03%)
Geotechnical drilling confirms grades at Fi Main and Ki pegmatites
The three summer 2025 holes were drilled specifically to collect whole-core material for rock mechanics testing, which provides essential data for future mine design and engineering studies. These holes targeted Fi Main, Fi SW, and Ki pegmatites and returned assay results after geotechnical analysis was completed.
At Fi Main, YLP-0304 returned 21 m at 1.09% Li₂O (incl. 13 m at 1.38%) from the upper dyke, plus 29 m at 0.56% Li₂O (incl. 9 m at 1.03%) from the lower dyke. At Ki, YLP-0306 returned 18 m at 1.41% Li₂O—the highest-grade intercept in this release. Fi SW returned lower grades: YLP-0305 returned 21 m at 0.50% Li₂O (incl. 8 m at 1.10%).
This geotechnical drilling serves a dual purpose, advancing engineering studies while confirming grade continuity at key deposits that already form part of the resource estimate.
Ki pegmatite context
Ki comprises a north-northwest trending dyke swarm extending at least 1.3 km on surface, dipping steeply southwest. YLP-0306 tested 100 m below surface, positioned 25 m downdip from prior 2023 drilling (YLP-104), successfully confirming mineralisation continuity at depth.

Yellowknife Lithium Project positioning and next steps
The Yellowknife Lithium Project comprises 13 mineral leases and one mineral claim totalling 1,504.7 hectares in the Northwest Territories, held 100% through wholly owned subsidiary Erex International Ltd. The project’s infrastructure advantages include proximity to Yellowknife, established road access, and an operational airport—factors that position the project favourably for continued development.
The company remains engaged in ongoing drilling and exploration work. The inferred mineral resource was released in October 2024 (TSXV) and May 2026 (ASX), and this drilling extends knowledge of the deposits beyond the resource boundary, particularly at BIG East where mineralisation remains open to the south and at depth. The combination of high-grade results, infrastructure access, and ongoing work positions the project for continued development.
Want to explore Li-FT Power’s lithium expansion potential at Yellowknife?
The winter drilling campaign has extended high-grade mineralisation at BIG East beyond the current resource boundary, with consistent intercepts above 1% Li₂O across 1,000 metres of strike. The system remains open to the south and at depth, suggesting significant room for resource growth.
