Reef mining in the district started in the late 1850s, but at this site a gold bearing quartz reef was first discovered in 1887 and "The Jubilee Quartz Mining Company" was formed.

Ore from reef mining ventures was commonly crushed in a stamp battery like this one near Mogo before being treated chemically to extract the gold. Power for the stamp batteries was often provided by traction engines with a belt and pulley system or by waterwheels. Note: • Only a snapshot of historical mining information is presented here.
An 1857 Royal Commission into the progress of the Victorian goldfields supported Murchison''s view that mining of the Bendigo quartz reefs would be shallow and shortlived. Miners on (and under) the ground, however, were disdainful of the views dispensed by scientific mining men on the other side of the world.
