Perth-based lithium exploration and development company Winsome Resources (ASX:WR1; “Winsome” or “the Company”) is pleased to advise it has partnered with geology specialist Mr Glenn Griesbach and with local prospector Mr Marc de Keyser.


  • Exclusive option agreement executed for Winsome to acquire and explore a further 259 claims, totalling 149 km2 in the highly sought after greater Decelles region of Quebec, Canada
  • Option agreement expands Winsome’s lithium exploration footprint in Quebec, enlarging Company’s recently acquired Decelles claim area by nearly 40%
  • This expanded area, known as Mazérac, is located around the Decelles Reservoir, about 50km southwest of Val-d’Or and easily accessible by a network of forestry roads
  • The region has seen much recent staking and prospecting activity, including highgrade spodumene discoveries by Vision Lithium at their nearby Cadillac property1
  • Enlarged property holding is highly complementary to Company’s 100% owned, existing projects in the James Bay region – Cancet, Adina and Sirmac-Clapier

The Company has entered into an exclusive option agreement to acquire 258 claims from Mr Glenn Griesbach and one claim from Mr de Keyser, totalling 149km2 in the prospective Mazérac region of Quebec, Canada. This is within the greater Decelles area, where the Company also acquired new property in January 20222 .

Mazérac is located close to the mining centres of Val-d’Or and Rouyn-Noranda, approximately 600km from Montreal. The Company has signed an exclusive option agreement to explore and subsequently acquire the claims over a 24-month period.

Mr Griesbach is a Canadian-certified geologist with more than 40 years of mineral exploration experience across Canada, Africa, China, and Southeast Asia. Mr de Keyser is a seasoned local prospector of First Nation heritage, with a strong understanding of the Mazérac region.

By entering into this agreement, the Company further expands its land holding in Quebec, exploring a new area of the province known for granitic and pegmatitic outcrops. The area is located close to infrastructure and the major mining centres immediately adjacent to recent lithium discoveries1 (see Figure 1 map)

Managing Director Chris Evans said:

“We are delighted to have entered into the option agreement for a further 259 claims at Mazérac in the Decelles region. There has been a considerable amount of recent lithium focused activity in the surrounding region, with several public and private companies making successful discoveries.

“By acquiring this project, we significantly increase the Company’s prospective lithium landholding in Quebec and continue towards achieving our vision of supplying high grade lithium products into the North American battery supply chain.”
