Archer Exploration has confirmed new, high quality graphite ores at Central Campoona will extend the life of their Campoona graphite project.
The South Australian explorer released results from testing on the second deposit discovered at their Eyre Peninsula lease, which revealed grades up to 98.8 per cent contained graphite.
Mineralisation is consistent with Campoona Shaft deposit, which means the same process flow circuit in their processing plant can be used without modification.
Archer managing director Gerard Anderson said the test results would open up significant new options for their newly proposed mine.
“The availability and tenor of Campoona Central’s mineralisation so close to Campoona Shaft gives flexibility to either increase the life of the current mine or increase our annual production of high-grade graphite in line with market conditions,” Anderson said.
“Critically, ore from both deposits can be simultaneously treated through the same circuit at our planned Sugarloaf Processing Facility to be jointly developed with the mines just 15 kilometres to the west of the two deposits.”
The combined resources of Campoona Shaft and Central Campoona are JORC 2012 compliant for 2.17 Mt at 9.6 per cent graphite for a total of 209,000 tonnes of contained metal.
Archer lodged the application to mine the Campoona tenement in May this year, with the expectation they will commence production in mid-2016.
The company expects to produce 10,000 tonnes of battery-grade product from Campoona Shaft each year, over a mine life of 14 years, with mining to then move to Central Campoona.
