Although the Firebrand is an old property, there is no published account of the work done on it until 1955. Two shallow shafts and a number of open cuts and a short adit have been excavated.

The workings occur along a quartz vein that strikes 340 degrees and dips about 65 degrees west. The host rocks are micaceous quartzite and quartz-mica schist which lie west of a layer of hornblende schist, all of the Mississippian to Lower Permian Milford Group. The vein is found intermittenlty along strike for about 150 metres.

Recorded production of 15 tonnes for 1924 shows that 56,981 grams of silver and 1,569 kilograms of lead were recovered.
