Thank you to L'Association de l'exploration minière du Québec for hosting us at the Xplor 2025 conference this past week in Montreal from October 27-30, and to everyone who stopped by our booth to learn more about our 100% owned Cheechoo Gold project. Until next time!

Our 100% owned Cheechoo gold project, is <15km from Éléonore mine (2.8Moz Au reserves, 2023/2024), has year-round road access and a 161 kV power line 5km away. Stay tuned for updates for how we are creating value for shareholders and stakeholders.

Our Cheechoo Project is ideal for mining development:
- Year-round Billy-Diamond Hwy and Eleonore mine road access
- Updated access road
- 161 kV power 5km away
- <15km from Eleonore mine's infrastructure & underused mill
- Located in a stable jurisdiction

The 2025 Cheechoo MRE boosted indicated grades by 19% & inferred by 38%. Exploration potential remains strong with room to upgrade resources via drilling. Project shows robust upside, justifying further geological work, and target generation programs for smarter targeting.

We boosted Cheechoo’s 2025 MRE grades by +19% (indicated) and +38% (inferred). Post NI43-101 update, we’re improving access roads to drive towards studies, and mining. With strong management & a tight-knit shareholder base, we’re set to unlock and deliver Cheechoo’s full value.

2025 MRE for Cheechoo gold project: A 19% & 38% increase in open pit indicated & inferred grades. Road improvements underway to advance towards production with an exploration target of 31-40 Mt at 1.27-1.45 g/t Au. Through disciplined exploration, we'll continue to drive value.

We are advancing our Cheechoo gold project by improving the access road. This enhances safety for heavy vehicles east of the Opinaca Reservoir, reduces environmental impact, lowers costs for Sirios, and improves access for the Cree of Wemindji community.
