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.
