LATE TRIASSIC
Small-scale Au and Bi mining has taken place at Mount Biggenden since the late 1880s. From 1967 to 1999, Commercial Minerals Pty |
Ltd produced magnetite for coal washing. J.S. McIntyre currently produces crushed aggregate from the waste dumps. |
Magnetite skarn occurs in hornfelsed mafic volcanics and metasediments of the Gympie Group close to the contact with the Degilbo |
Granite. Bismuth, gold and molybdenite mineralisation occur in the skarn. |
