Primary bismuth minerals from the Wolfram pipe, Kingsgate, New South Wales

Recent trial mining on the site of the Wolfram pipe on the Kingsgate field near Glen Innes, New South Wales, has unearthed a rich suite of bismuth minerals that have not been available for study since the early days of mining in the region. Aside from native bismuth and bismuthinite, Bi-rich mineralization carries significant amounts of galenobismutite and cosalite. Kobellite is locally abundant and represents a new primary mineral for Kingsgate. Other phases have been detected in small amounts, including treasureite. It is likely that the Bi-mineral suite at Kingsgate is more complex than has hitherto been thought.
