Resource Upgrade and Multi-Mineral Potential Highlighted in Adina Drilling Results
Winsome Resources has reported strong assay results from its 2025 drilling campaign at the Adina Lithium Project in Quebec, confirming thick, high-grade near-surface lithium mineralisation and advancing resource confidence ahead of a Feasibility Study.
- Infill drilling confirms thick, high-grade lithium in Main Zone
- Significant intercepts include 50.9m at 1.72% Li2O and 38.3m at 1.81% Li2O
- Footwall Zone drilling defines additional high-grade lithium zones
- Drilling supports upgrading Inferred resources to Indicated category
- Studies underway to explore extraction of critical minerals beyond lithium
Robust Drilling Results Reinforce Adina’s Potential
Winsome Resources (ASX, WR1) has delivered a compelling update on its 2025 drilling program at the 100% owned Adina Lithium Project in Quebec, Canada. The recent assays confirm the presence of thick, high-grade lithium mineralisation close to surface within the Main Zone, with standout intercepts such as 50.9 metres at 1.72% lithium oxide (Li2O) from just 3 metres depth, and 38.3 metres at 1.81% Li2O from 3.5 metres. These results underscore the project's potential as a significant, near-surface lithium resource.
The drilling campaign, funded through the Canadian Flow-Through Share scheme, was designed to increase confidence in the existing Mineral Resource Estimate (MRE) by converting material currently classified as Inferred into the higher confidence Indicated category. This is a critical step in advancing the project towards development, as Indicated resources carry greater certainty for feasibility and economic studies.
Expanding Understanding of the Footwall Zone
Beyond the Main Zone, Winsome’s drilling also targeted the Footwall Zone, successfully delineating additional high-grade lithium mineralisation at depth. Intercepts such as 11.3 metres at 1.55% Li2O from 254.6 metres demonstrate the zone’s potential to add meaningful tonnage and grade to the overall resource. The company plans to focus future drilling efforts here to match the data density of the Main Zone, which could further enhance the resource base.
Supporting Data for Feasibility and Environmental Studies
In addition to resource delineation, the drilling program collected vital geotechnical and hydrogeological data from holes positioned within current pit designs. This information will inform slope stability assessments and water management plans, essential components of the upcoming Feasibility Study. Such groundwork reflects Winsome’s methodical approach to de-risking the project and optimizing mine planning.
Exploring Multi-Critical Mineral Potential
Intriguingly, Winsome is also investigating the potential to extract other critical minerals from the Adina pegmatites, including cesium, tantalum, gallium, and rubidium. While the company’s Sirmac-Clapier project remains the flagship for high-grade cesium, preliminary data suggests promising gallium and rubidium concentrations at Adina. Conceptual process flowsheets are under development, though further test work and mineralogical studies are needed to confirm commercial viability.
Looking Ahead
With a current Mineral Resource Estimate of 78 million tonnes at 1.15% Li2O, 79% of which is Indicated, Winsome is well positioned to update its resource model incorporating the latest drilling results. These advances pave the way for a comprehensive Feasibility Study that will define the project’s economic parameters and support future development decisions. The company’s strategic focus on resource confidence, technical studies, and multi-commodity potential highlights Adina’s emerging profile as a tier-one lithium asset in a stable jurisdiction.
Bottom Line?
As Winsome integrates these robust drilling results into its Feasibility Study, the Adina Project’s path to production becomes clearer, but questions remain on the scale of multi-mineral opportunities.
Questions in the middle?
- How will the updated Mineral Resource Estimate impact the project’s valuation and financing options?
- What are the timelines and key milestones for the upcoming Feasibility Study and potential development decisions?
- To what extent can the extraction of critical minerals beyond lithium enhance the project’s economics?
