Union Hill Open Cut Mine
This mine illustrates two contemporary aspects of gold mining in Victoria and Maldon in particular. The mine is located on the site of the very successful Union & United Central mines of the late 1800s. Over 250,000oz of gold were removed from the area. Between 1988 and 1992, the open cut mine yielded 55,000ozs of gold after 1 million tonnes of rock were processed at the treatment works.
In 1995, underground mining was introduced when a 3 meter wide x 3 meter high decline under the existing open cut pit commenced. The 1 in 7 decline made use of the modern drills and trucks viable, unlike earlier mines using vertical shafts and overhead winding gear.
