Reichenbachite, Kipushite Locality: Kipushi Mine (Prince Léopold Mine), Kipushi, Katanga (Shaba), Democratic Republic of Congo (Zaïre) (Locality at mindat.org) Size: 3.8 x 3.5 x 2.9 cm. The two, very well-placed vugs atop gossan matrix are covered with sparkly, botryoidal and matte, leaf-like reichenbachite after kipushite crystals. Reichenbachite is a copper phosphate and kipushite is a copper, zinc phosphate. This is old material from the 1960s or 70s. Mineral

Rhabdophane-(Ce) (FOV 1.8 x 1.2 mm) Locality: Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada Original description: There was a great deal of rhabdophane-(Ce) in this find but most of it was not well crystalyzed. This is one of the better isolated xls. Associated minerals included acicular radiating epididymite (XRD) and pyrochlore coated with a grainy yellow substance (not analyzed). These minerals are not visible in these photos. Mineral
