Protium Clean Energy Corp. is a Canadian junior exploration and development company engaged in the acquisition, exploration, and advancement of natural resource properties focused on clean energy commodities and critical metals. The company's primary operations and resource assets encompass: natural geologic hydrogen exploration and evaluation, including the Firstbrook Hydrogen property located in Northern Ontario as well as exploration targets in British Columbia utilizing satellite gas detection surveys; lithium exploration and development, headlined by the 100%-owned Nakina Lithium property in Northern Ontario; and critical minerals exploration, featuring tungsten assets including the Emma Prospect and the Ten O'Clock Mine located in the Gabbs mining district of Nevada, United States. Operating across the basic materials and clean technology sectors, the company focuses on identifying and delineating resources to serve the global transition toward decarbonization, renewable energy systems, electric vehicle batteries, and high-temperature industrial alloy applications. Protium Clean Energy Corp. conducts its operational and exploratory activities primarily across Canada (Ontario and British Columbia) and the United States (Nevada). Founded in 2007 and headquartered in Vancouver, British Columbia, Canada, the company previously conducted business as Eagle I Capital Corporation and Weekapaug Lithium Limited. In recent corporate developments, the company changed its name from Weekapaug Lithium Limited to Protium Clean Energy Corp. in November 2024 to reflect its expanded mandate in clean energy and natural hydrogen exploration. In August 2026, the company closed the acquisition of the historic Emma Prospect and Ten O'Clock Mine tungsten properties in Nevada for cash consideration and common share issuances to expand its North American critical metals footprint, following the completion of an oversubscribed private placement in March 2026 raising approximately CAD 1.08 million to accelerate exploration across its geologic hydrogen, lithium, and mineral portfolios.
