A small abandoned copper-lead-zinc-gold mine about 44km NW of Pine Creek.
It is a polymetallic massive sulphide deposits with mineralization including gold, silver, lead, zinc and copper. The deposits are developed within a folded Proterozoic sedimentary sequence. The mineralization occurs within lodes oriented in a north-south direction steeply dipping at approximately 70° to the east.

Located approximately 44 kms north-west of Pine Creek and 140 kms south-southeast from Darwin.

Mt Bonnie was first discovered in the early 1900s and was developed as an underground mine between 1912 and 1916. It was then dormant until 1973 when Geopeko drilled the property. Geopeko completed a historical resource estimate of 480,000 tonnes at a grade of 1.5 g/t gold, 186 g/t silver, 7.7% zinc, 1.8% lead and 0.4% copper.


NOTE: transparent "hedyphane" crystals from "Beltana" have been sold at mineral shows, but these crystals look like mimetite from the Mt. Bonnie mine (comm. Peter Elliott; see also discussion in http://www.mindat.org/mesg-106-373206.html).
