Critical One Energy has entered into a memorandum of understanding (MoU) with Green Infrastructure Partners (GIP) to support work at the Howells Lake Antimony-Gold Project in Ontario, Canada.
The agreement is expected to establish a framework for GIP to contribute to road planning, civil engineering, workforce training and contract mining services at the Critical One Energy site, which is located around 120km west of the Ring of Fire access corridor.

Under the MoU, the scope of work includes road construction and civil works, as well as certified heavy equipment operator training delivered to First Nation community members in partnership with Fleming College in Lindsay.
The training will be provided through the Parnham Family Student Endowment. GIP will also have a first right of refusal on contract mining and material supply related to the Howells Lake Antimony-Gold Project.
Critical One Energy founder, executive chairman and CEO Duane Parnham said: “We have advanced our Howells Lake Project from a historic antimony-gold system into an active, permitted project, with drilling of high-grade antimony, including near-pure stibnite.
“This drill work supports the Howells Lake Project’s potential as a direct-shipping-ore route to military and industrial buyers, and GIP helps us plan the road access, infrastructure and haulage of ore to market.
“We now have the asset, the permits and the partners to position Howells Lake as a North American source of critical minerals for defence, technology and clean energy.”
The agreement aims to align project infrastructure with larger critical minerals infrastructure developments under way in northern Ontario, including the Ontario Ring of Fire road programme.
Construction is scheduled to commence in June 2026.
Critical One Energy stated that the MoU has an initial term of 24 months and remains non-binding until the completion of definitive agreements.
Execution of the final agreements will depend on further commercial negotiation, cooperation with the Eabametoong First Nation, regulatory approvals and relevant permits.
In September 2025, Critical One Energy announced the acquisition of an 18.5% interest in Dark Star Minerals, an exploration company focused on uranium projects in the Erongo region of Namibia.
