Cesium Project Pipeline
The following projects represent the most significant Cesium operations and development-stage assets worldwide:
Tanco Mine
Sinomine Resource Group
Located at Bernic Lake, Manitoba; one of only three known economic pollucite deposits globally; now Chinese-owned following Sinomine acquisition from Cabot
Bikita Minerals
Sinomine Resource Group
Lithium-focused mine with pollucite as a byproduct; also acquired by Sinomine
Sinclair Caesium Project
Pioneer Resources (historical)
One of few known pollucite occurrences outside Tanco and Bikita
Government Support and Strategic Initiatives
Recognizing the strategic importance of Cesium, governments in major consuming nations have launched programs to support project development. These include direct financing, loan guarantees, streamlined permitting, and bilateral resource partnerships. As a USGS-listed critical mineral, Cesium projects are eligible for various U.S. government support mechanisms including the Defense Production Act Title III program. EU Critical Raw Materials Act provisions enable fast-track permitting and financing support for Cesium projects within the EU and partner nations.
Key Industry Developments
Recent developments affecting the Cesium project landscape:
Chinas Sinomine Resource Group acquired the Tanco mine from Cabot Corporation, giving China effective control over the worlds primary cesium source
Sinomine also acquired Bikita Minerals in Zimbabwe, consolidating control of two of three known pollucite deposits under Chinese ownership
US and Canadian officials raised national security concerns about Chinese control of the Western worlds primary cesium supply from the Tanco mine
