Gold was first discovered in the Maldon area around 1854.
Various mines were worked through to around 1926 with minor sporadic investigative work carried out in the 1980s-1990s.
By 1926, about 1.8 Moz (56 t) of gold had been won, at an average grade of 28 g/t
Over twenty quartz reefs were worked along a N–S trending belt some 6 km long and 3 km wide.

Mineralization age: Late Devonian : 376 ± 2 Ma

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
