Uraninite var. Pitchblende, Silver: Port Radium, Northwest …
This is a spectacular large specimen of extremely high-grade uranium ore from a classic and remote Canadian locality, Port Radium. What makes it special, though, is a 1 cm. vein of beautiful dendritic silver crystals in calcite cutting across the pitchblende and hematite ore. Just an awesome ore specimen and very unique!
