Archer Exploration’s graphite resource areas are on eastern side of the Eyre Peninsula, between the townships of Cleve and Kimba.


ARCHER Exploration has announced a combined JORC 2012 graphite resource at its Eyre Peninsula project in South Australia of 8.55 million tonnes @ 9.0% graphitic carbon for 770,800 tonnes of contained graphite. This is the largest JORC 2012 graphite resource in Australia.

The Eyre Peninsular project encompasses the Campoona and Sugarloaf deposits as well as the recently acquired Wilclo South area. The estimate is based on a 5% cut-off grade and utilizes the JORC 2012 definition of ‘reasonable prospects of eventual recovery'.

Archer's managing director Gerard Anderson says, "With exposure to large flake graphite at Wilclo South and high purity graphite at Campoona, we now have a range of flake sizes across our tenements that allows us to target a wide spread of end graphite users."

"Our access to infrastructure and location in a safe and reliable mining jurisdiction provides us with a competitive position as the project is developed further."

At Campoona Shaft there are 320,000 measured tonnes @ 12.7% for 40,600 tonnes of contained graphite, 780,000 indicated tonnes @ 8.2% for 64,000 tonnes and 550,000 inferred tonnes @ 8.5% for 46,800 tonnes. At Central Campoona there are 220,000 indicated tonnes @ 12.3% for 27,100 tonnes and 300,000 inferred tonnes @ 10.3% for 30,900 tonnes. At Wilclo South there are 6.38 million inferred tonnes @ 8.8% for 561,000 tonnes.

The Wilclo South resource estimate represents only a very small strike length, 1.4km, of the more than 10km of strong linear EM conductors. There is significant potential for further resource growth. In addition to the Wilclo trend there are five other graphite prospects corresponding to strong linear EM conductors aggregating an additional 10km of potential strike that has been the subject of only limited drilling.

Gerard Anderson says, "Given our strong financial position, our immediate next step will be to drill test our additional graphite prospects to further build on our resource base and enable a ranking of deposits based on deposit size, graphite size distribution and purity of graphite in concentrates."

The company is also undertaking a re-design of the process flow sheet for the proposed Sugarloaf processing plant in order to accommodate the large flake graphite product and the high purity graphite expected to be produced from Wilclo South and Campoona respectively. The expanded graphite resource and the new process flow sheet will underpin a scoping study which will assess the potential viability of the Eyre Peninsula project.

All reported resources are within a 30km radius of the proposed graphite processing facility at Sugarloaf.
