Uraninite - Eldorado Mine, Port Radium, Great Bear Lake, Northwest Territories, Canada

This striking cut specimen features classic dendritic uraninite from the legendary Eldorado Mine at Port Radium, a locality synonymous with some of the most historically significant uranium ever mined. The polished face reveals intricate, branching uraninite growth patterns set against the host matrix, offering exceptional visual contrast and making the internal structure of the mineral clearly visible. Pieces from Port Radium are increasingly scarce, especially well-prepared examples that showcase dendritic textures so clearly.

Beyond its aesthetic appeal, this specimen represents an important chapter in Canadian and global nuclear history, originating from one of the world’s most influential uranium producers of the 20th century. Due to its radioactive nature, this specimen is intended for advanced collectors only who are familiar with proper handling, storage, and regulatory considerations associated with radioactive minerals.
