Archer Exploration

Graphite

Graphite presents a significant and rapidly emerging opportunity for Archer.

EYRE PENINSULA GRAPHITE
The Eyre Peninsula Graphite Projects comprise the Campoona Project and the Carappee Hill Project. Campoona has a JORC Resource of 5.27 million tonnes @ 7.6% TGC (based on 2% cut off). Carappee Hill has an Exploration Target* of 37-70Mt grading 10-12% C.

(link to studies completed and community newsletters) 

What sets Campoona apart from almost all other graphite deposits in the world is its ability to deliver ultra pure, high value, highly crystalline ultra-fine graphite using conventional mechanical cell flotation.

The Campoona Graphite Project comprises the Campoona Shaft and Campoona Central project areas, located 15km north of Cleve on Eyre Peninsula, South Australia.

Proximity to infrastructure
Campoona is located close to infrastructure with existing high voltage power line and gazetted truck routes running through the tenement area (refer to map).

JORC Resource
In December 2012, the Company announced a JORC Resource at Campoona. The JORC Resource was achieved within 9 months of the drilling of the discovery hole.

Metallurgy
Campoona is unique in that it can deliver very high quality graphite from a low cost, high yielding extractive process. Metallurgical bench-scale testing of representative diamond drill core samples of Campoona graphite has resulted in recoveries of >99% TGA (total Graphitic carbon completed using Thermogravimetric Analysis accurate to ±1%carbon).

SUGARLOAF PROJECT
The Carappee Hill (Sugarloaf graphite deposit) Project (EL 3711) is located within 15km of the Campoona Project. Drilling at Carappee Hill has identified an Exploration Target* of 37-70Mt grading 10-12% C.
