Adina, a flagship project

The Adina project, Winsome team’s flagship project, was discovered in 2014 by the MRNF (government) geologist Adina Bogatu during regional mapping work. In 2018, a 1,726-metre drilling campaign was carried out on the main showing confirming the presence of a small-scale mineralized system.

In fall 2022, an exploration team working on behalf of Winsome made the discovery of the JAMAR showing, located 1.2 km directly east of the original showing. The showing was named to honor the team composed of Jason, Anaïs, Monserrat and Arnaud. They were looking for a place to land the helicopter, and the only accessible area covered the discovery outcrop. Initial drilling confirmed the significance of the discovery, with a 107.6 metre section grading 1.34% Li2O, drilled along the main trend of the zone.

The 150 or so diamond drill holes completed since then have highlighted a vast zone extending over just over 3 km and hosting high-potential lithiniferous grades. In addition, this mineralized zone has been intersected by peripheral drilling to both the east and west, suggesting that the mineralized system extends beyond the current core.

In late fall 2023, Winsome released its first mineral resource estimate for the Adina property. The very promising results released on December 11th officially establish Winsome as one of Quebec’s most important lithium projects (press release).

In spring 2024, other promising discoveries were made, including the discovery of a new area 200 metre southwest of Adina. The results then confirm the presence of high-grade mineralization with a section of 61.5 metre at 1.62% Li2O, including 24.0 metre at 2.82% Li2O (press release).

On May 28, 2024, the company updated its mineral resource estimate and confirmed a 33% increase to 77.9 Mt at 1.15% Li2O. The mineral resources correspond to more than 2.21 million tonnes of lithium carbonate equivalent (LCE) and confirm Adina’s positioning as one of the largest unexploited lithium deposits in the world.

Projet Adina - Winsome resources

Winsome also holds an option to acquire a full interest in the Jackpot property, adjacent to and along the northern edge of the Adina project. Once the option is exercised, the surface area of the Adina project would be increased by approximately 50%.

Located at the very heart of our assets, the Adina project offers a considerable geographical advantage, paving the way for possible synergies with the parallel development of our neighbouring Cancet and Tilly projects, located just a few dozen kilometers away.

Winsome also plans to acquire the Renard mine, with the possibility of converting its infrastructure to process lithium ore from the Adina project.
