The Chilcot mine orebody is a steeply dipping, well defined fissure zone of brecciated andesite, with chalcopyrite in shoots, averaging about 8 per cent copper. Other minerals are bornite, pyrite, hematite, magnetite, quartz and calcite. Pre-ore faults displace the lode channel and are associated with the mineralisation. The ore body is developed by two levels 160 feet in length at 104 and 178 feet depth, and ore is being extracted from a stope between the two levels northeast of the shaft. Water level is a little over 100 feet from the surface. The general pitch of the ore body is about 45 degrees to the northeast. Exploration is recommended of the probable northeast extension of the lode down the pitch, and geophysical investigation to attempt to locate further possible shoots of ore.
