This exceptional uraninite specimen hails from the historic Ace Deposit within the Beaverlodge Lake district, one of Canada’s most renowned uranium-producing regions. Mined by Eldorado Mining & Refining Ltd., this piece represents the rich legacy of Canadian uranium exploration during the mid-20th century. Acquired from the George Kamin collection, a name well-known among serious collectors, it carries provenance that adds significant historical and mineralogical value. The specimen showcases well-formed, lustrous uraninite crystals with deep, pitch-black coloration, reflecting the classic characteristics of high-quality Beaverlodge material.

The uraninite exhibits a compact, crystalline matrix that highlights the mineral’s natural octahedral crystal habit, with subtle variations in texture and surface reflection that make it a visually striking addition to any collection. Its dense, metallic appearance contrasts beautifully against the lighter matrix, demonstrating the geological conditions under which it formed. Collectors will appreciate the combination of historical significance, aesthetic appeal, and scientific interest, as this piece also serves as an excellent reference sample for mineralogical study and radioactive mineral identification.

Due to its uranium content, this specimen is highly radioactive and requires careful handling, making it suitable for experienced collectors who are familiar with proper storage and safety protocols. Despite its radioactivity, it remains a captivating showcase of Canadian uranium geology and offers both an educational and aesthetic experience. With its proven heritage, quality, and classic uraninite characteristics, this piece is a remarkable example of a true mineralogical treasure from Saskatchewan.
