  Lusungite   Kintoreite

Comments: Greenish-yellow kintoreite crystals on limonite and or goethite. The specimen was originally labelled lusungite in the early 1990's and reinvestigation of the specimen showed it to be kintoreite.
Location: Kintore Open Cut, Broken Hill, NSW, Australia. Scale: Specimen Size 3x6 cm.
