Tangse
Previous limited drilling by CRA (Conzinc RioTinto Australia) in the 1980s at Tangse outlined a large porphyry copper-molybdenum deposit containing a coherent zone of copper-molybdenum mineralization five kilometres long and one to two kilometres wide. Historical order of magnitude estimates (non-NI 43-101 compliant) are at least 600 million tonnes (Mt) of lower grade material, including a higher grade zone of 30 Mt with grades between 0.3 and 0.8% copper (Cu), and 0.02 to 0.03% molybdenum (Mo) (van Leeuwen et al, 1987).

The Tangse porphyry system has been subjected to widespread supergene enrichment. This is most prevalent in the higher grade, hypogene portion of the deposit where the primary copper grade has reportedly been upgraded by a factor of 1.5 to 3, to grades in excess of 1% copper. EAS exploration will initially focus on this enriched zone.

The Tangse project has excellent logistics, and is located only 100 kilometres to the southeast of the Provincial capital of Banda Aceh. It is adjacent to a main regional highway and the power grid.
