The Kanmantoo Copper Mine is located in the Adelaide Hills region of South Australia, an area which remains one of the most under explored and prospective base metal provinces in Australia, showing outstanding potential for copper-gold and silver-lead-zinc mineralisation.
The project contains the old Kanmantoo Copper Mine pit, which was in operation from 1970 until 1976, but work by Hillgrove since 2004 has proved up an additional Indicated and Inferred Mineral Resource of 34.5 million tonnes grading 0.6% copper (211,000 tonnes metal) and 0.1g/t gold. Exploration work continues in an effort to prove up additional resources in the pit area and beyond with a view to expanding the size and life of the project.
The project's location, 55 kilometres by road from Adelaide's CBD, brings significant inherent operating and capital cost advantages. The mine accesses low cost grid power and uses treated waste water from the nearby town of Mount Barker, and is three kilometres from the main dual carriageway South Eastern Freeway that leads to Adelaide and the export port of Port Adelaide. The mine's location in the Adelaide Hills - one of South Australia's most attractive settings - also helps to attract and retain a high quality workforce who predominantly live within the region.


Key Aspects

The Government of South Australia stands behind the development of a vigorous mining industry and has implemented an exceptionally supportive regulatory environment. A Mining Lease was granted by Primary Industries and Resources SA (PIRSA) in 2009, with the associated Mining and Rehabilitation Plan (MARP) fully approved in April 2010 and a further PEPR approval to extend the mining area and mine life from 2016 to 2019 was approved in July 2014. The Minerals and Energy Resources division now sits within the Department of State Development (DSD) and current details of the project are located on their site at http://minerals.statedevelopment.sa.gov.au/mining/mines_and_quarries/kanmantoo.
Ample water is available to operate the mine, with the majority of its process water coming from treated waste water from the District Council of Mt Barker's Laratinga Water Treatment Plant via a 15km pipeline that runs through to Callington, which Hillgrove assisted building, providing environmental and other benefits through sustainable water resources management. The project will also use low cost grid sourced power with electricity supply arranged with Electranet.
Approximately 245 personnel staff the mine.  Available roles are advertised via the on-line portal on our Careers page or via SEEK.  Working in a populated area, with a large stock of local housing, schools and hospitals nearby, the project enjoys low staff turnover and is not burdened by fly in/fly out and capital costs incurred by traditional remotely sited mines.  Consequently, we endeavour to fill as many roles as possible locally or within the region.  It is very gratifying for employees to reduce their travel time, see their families daily and be a part of an exciting venture within their region.

The potential for further discoveries and growth of the global copper/gold resource at Kanmantoo is high. The deposit appears to remain open along strike and down dip where additional drilling could materially increase the resource inventory. The Project's regional exploration prospects range from grass roots to those with significant intercepts and resources, which it is hoped will add additional resources. Further additions to the Mineral Resources at depth and along strike of the open pit, if converted to Ore Reserves, could result in expansion of the open pit, increases in the mining rate and extension of mine life.


Members of the Callington and Kanmantoo communities are invited to attend the next Kanmantoo-Callington Community Consultative Committee meeting at:  

Thursday 19th March, 2020
7:30pm to 9:30pm
at Callington Memorial Hall


Projected to operate as a ten year open-cut mine with throughput of over 3.0Mt pa, producing approximately 100,000t of concentrate, containing about 20,000t of copper metal and associated gold per annum with exploration potential for further copper-gold mineralisation.


We are mindful that we are operating in and around local landowners and communities and it is our greatest wish to see all benefit from our presence.
