PureBase Rare Earths Inc. (OTCMKTS: PUBC) is a Canada-based mineral exploration and development company focused on building a fully integrated rare earth supply chain. Originally founded as North American Nickel, the company rebranded to PureBase in 2021 to reflect its strategic shift into high-purity rare earth elements. PureBase’s activities span from grassroots exploration to pre-commercial production, targeting critical magnet rare earths that underpin modern electric vehicles, wind turbines and advanced electronics.
At the core of PureBase’s portfolio is the Weishan Project in Shandong Province, China, an I-type deposit rich in neodymium, praseodymium and dysprosium. The company also holds exploration licences in Canada and has established a technical office in China to oversee pilot plant operations and metallurgical testing. Through systematic drilling campaigns, mineralogical studies and hydrometallurgical process development, PureBase aims to advance its flagship asset toward scalable output of separated rare earth oxides.
PureBase’s product roadmap centers on the production of light and heavy rare earth oxides, including NdPr oxide for high-strength permanent magnets and dysprosium-terbium concentrates for enhanced magnetic performance at high temperatures. To accelerate market entry, the company is exploring partnerships with downstream processors in Asia and North America, leveraging proprietary flowsheet designs to optimize separation yields and reduce environmental impact. These efforts position PureBase to supply the growing global demand for critical materials in clean energy and high-technology sectors.
Headquartered in Vancouver, British Columbia, PureBase is led by a management team and board of directors with decades of experience in mining, metallurgy and corporate finance. Senior leadership combines technical expertise in rare earth deposit characterization with commercial know-how in commodity markets. With a dual presence in North America and China, PureBase is structured to navigate regulatory, logistical and market challenges as it seeks to establish one of the world’s few non-state controlled sources of magnet rare earths.
