North Queensland Copper Operations

North Queensland Operations comprises the underground Mt Colin copper mine, the Barbara development project and a prospective, 1,102km2 tenement package in the Mt Isa/Cloncurry region. It was acquired by Aeris Resources in July 2022 through the acquisition of Round Oak Minerals.

Originally an open cut operation, Mt Colin produced its first ore from underground activities in September 2019. Ore is mined using by an underground mining contractor using long hole open stoping methods. Run of mine ore is crushed on site before being transported by road train to the Ernest Henry processing facility north of Cloncurry for toll treatment. The copper-gold concentrate produced is then railed to the Port of Townsville for export.

Development and Exploration Projects

With production at Mt Colin due to be completed in FY2024, development activities are focused on the nearby Barbara deposit. Barbara was previously mined as an open pit operation with a significant copper-gold resource remaining below the pit. Aeris will undertake further mining studies to investigate the potential of a new underground operation at Barbara as Mt Colin winds down.

In addition to the Mt Colin and Barbara mines, North Queensland Operations also includes a large regional exploration package. The tenement package is divided into three main areas:

  • Hazel Creek area, incorporating the Turpentine deposit with a historic (JORC 2004) resource estimate)
  • Central Exploration area near Cloncurry
  • Soldiers Cap area to the south of Cloncurry

The tenement package is considered prospective for IOCG-style copper-gold deposit as well as Mt Isa type lead-zinc-silver deposits.
