Malaysia, 50 per cent ownership, Copper and Gold

The Tampang project is a joint venture, (the Ranau Joint Venture) with Malaysian partners Mega First Sdn Bhd, which covers a region of porphyry copper gold mineralisation in Sabah, Malaysia on the island of Borneo, 65 kilometres east of the state capital of Kota Kinabalu.

The exploration project comprises two Prospecting Licences covering 327 square kilometres.  

Exploration commenced in 1996 under the 50:50 joint venture. Perilya is the exploration project manager.


The project is located in an area that hosts a number of intrusive granodiorite to monzonite stocks, collectively referred to as the Kinabalu magmatic zone, and is 10 kilometres east of the Mamut porphyry copper-gold mine.

Porphyry copper deposits in the Malaysia/Indonesia/Papua New Guinea island arc are usually associated with high-level porphyritic, monzonite to diorite stocks intruded into volcanic and sedimentary rocks. Grades are typically less than 1 per cent copper and 1 g/t gold, but can be higher. Epithermal gold deposits can also be formed in favourable structural and lithological settings near these porphyry stocks.

The main prospects at Tampang are Bongkud, Junction and Napong, which were discovered early in 1999 close to the township of Ranau and consist of coincident gold-copper in soil and geophysical anomalies.

The porphyry system is interpreted to dip south at approximately 45 degrees and is open down-dip and to the west.

Additional copper-gold porphyry prospects warranting investigation in the Kinabalu magmatic zone include the Bambangan, Luminantai and Paliu prospects which all occur within 20 kilometres of the Mamut mine.
