pechblende contenant de l'argent

OBS: Il y avait deux types de minerai à Port Radium : la pechblende imprégnant une haute teneur en silice et la pechblende imprégnant de la baryte carbonatée, qui renfermait aussi de l'argent (Traill, 1932).

OBS: There were two distinct types of ore at Port Radium: a high silica-gangue type pitchblende; and a carbonate barite gangue type pitchblende which also contained silver (Traill 1932).
OBS: Pitchblende is commonly associated with one or more of the primary ore minerals of iron, copper, cobalt, lead, silver, and bismuth; and the presence of these minerals in a mineral deposit is one indication of favorable conditions for pitchblende. It is usually accompanied also by bright colored secondary uranium minerals where subjected to weathering or other alteration.
