Highlights

Assays from the first 17 of 65 holes at Spodumene Mountain returned broad, high-grade lithium intercepts.
Hole BL26-041 returned 84.0m at 1.84% Li2O from 8.0m.
The known strike length has grown to about 1.4km, and the prospect remains open in all directions.
A maiden Mineral Resource Estimate is targeted for H1 2027, subject to assay results.

WhiteRock Lithium Corp. (ASX:WLC) has reported assay results from the first 17 of 65 holes in its 2026 diamond drilling program at the Spodumene Mountain prospect, part of the Banana Lithium Project in Québec, Canada. Pegmatite was intersected in every hole of the 19,481m program.

High-Grade Drilling Results

Hole BL26-041 returned 84.0m at 1.84% Li2O from 8.0m. Other strong intercepts include 51.0m at 2.24% Li2O in BL26-044, 37.9m at 2.47% Li2O in BL26-045, 38.6m at 2.29% Li2O in BL26-038 and 40.9m at 2.16% Li2O in BL26-033.

In the central zone, three holes reported high-grade, stacked pegmatites near surface. In the northeast zone, all eight holes reported so far returned at least one interval of about 2% Li2O or higher, with pegmatites interpreted to widen down dip.

Growing Footprint and Metallurgy

The known strike length has grown from about 650m to about 1.4km, and drilling has extended about 500m down dip. The company said the prospect remains open in all directions, along strike and at depth.

Preliminary heavy-liquid separation testing produced concentrates above 6% Li2O with 63–87% recovery, suggesting dense media separation as a viable primary process. Notable tantalum values were also recorded.

Next Steps Toward a Maiden Resource

Further assays are expected in the coming weeks. Subject to results, WhiteRock is targeting a maiden Mineral Resource Estimate for Spodumene Mountain in H1 2027.

The project's Exploration Target, which the company notes is conceptual, is 190–275Mt at 1.2–1.6% Li2O across Spodumene Mountain, Isabella and Marine. WhiteRock holds 100% of the project.

Key Takeaways

Early assays confirm broad, high-grade lithium mineralisation.
The known strike length has more than doubled to about 1.4km.
Preliminary metallurgy supports a simple DMS process.
A maiden resource is targeted for H1 2027.
