CRITICAL ONE ENERGY RECEIVES ONTARIO GOVERNMENT FUNDING GRANT FOR HOWELLS LAKE ANTIMONY-GOLD PROJECT EXPLORATION WORK

Critical One Energy Inc. has received official approval from the Ontario government for initial funding under the Ontario Junior Exploration Program (OJEP)'s 2025 to 2026 intake. This grant will support the company's continuing efforts to explore the Howells Lake antimony-gold project located approximately 120 kilometres (km) west of the Ring of Fire road corridor in the Thunder Bay mining district of Ontario.

The OJEP grant, administered by the Ontario Ministry of Mines, provides financial assistance to junior exploration companies to offset costs associated with grassroots mineral exploration projects. Critical One's approved project focuses on identifying and evaluating high-potential sites for critical, precious and other minerals in Northern Ontario, aligning with the province's commitment to bolstering domestic supply chains for electric vehicles, renewable energy technologies and advanced manufacturing.

"This approval marks a significant milestone for Critical One as we continue to push the boundaries of sustainable resource development of antimony and other critical metals," said Duane Parnham, founder, executive chairman and chief executive officer of Critical One. "The company's quality management practices and strategic importance of our Howells Lake project are attracting grants like this one, demonstrating the confidence that government and industry stakeholders have in our vision for a brighter future."

The funding will enable the company to accelerate upcoming drilling work while ensuring responsible exploration that prioritizes community engagement and ecological stewardship. The company anticipates commencing enhanced activities in the spring of 2026, with preliminary results soon thereafter.

Critical One remains committed to transparency and collaboration with local indigenous communities, stakeholders and regulatory bodies throughout the project life cycle.

The Howells Lake project represents one of Canada's largest known undeveloped antimony systems, with a historical resource of 1.7 million tons at a grade of 1.4 per cent antimony with associated gold mineralization. Historical drilling has returned exceptional grades, including individual assays up to 75 per cent antimony and over 14 grams per tonne gold, as well as intervals such as 5.37 per cent antimony over 8.35 metres and associations with high-grade gold. The project spans a substantial land package of approximately 25,000 hectares across a 30-kilometre strike in a proven greenstone belt, positioning it as a key asset in addressing North America's growing demand for critical minerals amid supply chain constraints and elevated antimony prices.

Additionally, the QP has not done sufficient work to make the resource current. Drill intersections are reported as downhole intervals. No true width could be determined at this time. The information in the data recovered is considered of value and relevant to the company's project. However, the issuer is not treating the estimate as current.
