Winsome among Quebec’s top lithium projects

Val-d’Or, December 11th 2023 – We are proud to share the highly promising results of the maiden mineral resource estimate (MRE) for our Adina Lithium Project (Adina), located in the Eeyou Istchee James Bay region of Quebec.

This first MRE of 59Mt at 1.12% Li2O confirms the exceptional lithium potential of our claims and confirms Winsome Resources’ (Winsome’s) place among the world’s major lithium players.

This MRE positions Winsome as one of the top 5 lithium projects in Quebec, among the top 10 in North America, and globally in the top 20.

“The announcement of our maiden MRE marks a significant milestone for the Adina Lithium Project and is an historic moment for Winsome Resources. Just over a year ago, our first sampling expedition began at Adina, and it is a remarkable achievement by our exploration team to have since declared one of the largest hard rock MREs in North America,” said Chris Evans, Managing Director.

These results are the fruit of our team’s expertise, particularly our field team’s ability to target sites of interest for the drilling campaign, as well as the valuable collaboration developed with the Eeyou Istchee James Bay community in Quebec.

The announcement of the MRE is an important milestone, paving the way for other milestones to come, including the preliminary economic assessment and the pre-feasibility study, which are expected in the second half of 2024.

With these excellent results, Winsome is well positioned to meet the growing global demand for lithium and is more determined than ever to play a leading role in Quebec and Canada’s strategy for critical and strategic minerals.

Winsome remains committed to acting in a spirit of collaboration and sharing with local communities, and to setting exemplary industry standards in environmental protection.
