WhiteRock Lithium (ASX:WLC) has extended the strike length at its Spodumene Mountain prospect to 1.4km after all seven new drill holes intersected spodumene pegmatite.
Visual results from the first seven holes of its 2026 drilling program at the Banana Lithium Project in Québec, Canada, confirm spodumene pegmatite mineralisation along both strike directions.
According to WhiteRock, the strike length has increased 115% from 650m to 1.4km, with 350m added to the southwest and 400m added to the northeast beyond the outermost 2024 drill holes.
Coarse-grained spodumene mineralisation was observed in all drill holes, with intersections up to 77.4m of pegmatite. The lithium-caesium-tantalum (LCT) pegmatite system remains open along strike and at depth.
Chairman and chief executive Simon Hay says the results represent a significant milestone for the company.
“More than doubling the strike length at Spodumene Mountain to 1.4km, with spodumene pegmatite confirmed in every new drill hole, demonstrates the scale and continuity of the system,” Hay says.
“The fact that the LCT pegmatite remains open along strike and down dip suggests that the full potential of the Banana Lithium Project has yet to be revealed.”
Four drill holes tested the northeastern extension, extending the pegmatite trend 400m northeast of the furthest 2024 drill hole.
Meanwhile, three drill holes tested the southwestern extension, extending the footprint 350m southwest.
Key pegmatite intercepts include 68.5m with spodumene abundance estimates of 0.1–25% in hole BL26-030, 40m @ 15% to 25% spodumene in hole BL26-031, and 77.4m with 0.1%–25% spodumene distribution in hole BL26-035.
Seven holes totalling 1,903m of drilling have been completed out of a planned 50 to 60 holes. WhiteRock says three diamond drill rigs continue to test the mineralised corridor on a 100m by 100m grid.
Assay results are expected within approximately three weeks. Pending drilling results, WhiteRock plans to compile a maiden mineral resource estimate in the first half of 2027.
WhiteRock holds a 100% interest in the 67,000-hectare Banana Lithium Project across the Nunavik and Eeyou Istchee James Bay regions of northern Québec.
