Venus State Battery, Stamper battery in Millchester, Charters Towers, Queensland, Australia

Venus State Battery is a gold processing facility in Millchester with timber frame buildings and corrugated iron coverings. The site contains four ore bins and multiple stamp batteries designed to crush and process minerals extracted from local mines.

The facility was constructed in 1872 and initially operated five stamp batteries, which increased to twenty by the following year. It became one of the earliest operations of its kind established in Queensland.

The battery's name comes from the Venus claim, and the site is also called the Venus Gold Battery and Venus Mill; on the Charters Towers gold field "mill" meant a stamper or crushing battery. From 1919, when the Queensland Government took ownership, ore was brought for public crushing from as far as Chillagoe, the Woolgar River and Iron Range on Cape York Peninsula.

The site is located on MacDonald Street and has been managed as a heritage property by the National Trust of Queensland since 1975. Visitors can access the grounds on foot and find the location easily by its street address.

A Cornish boiler was repurposed into an elevated water tank and remains in place at the facility today. The original weir on nearby Gladstone Creek still stands as part of the historical infrastructure.
