Sepon Gold and Copper Operations
Oxiana owns the Sepon gold and copper operations. The Sepon project comprises a 1,250 square kilometres contract area located approximately 40 kilometres north of the town of Sepon, in Savannakhet Province, south-central Laos.
Oxiana has been producing gold at Sepon since December 2002 and copper since early 2005.
Background
In 2000, Oxiana acquired 80% of the Sepon Project from Rio Tinto. Oxiana acquired the remaining 20% in early 2004. The Government of Laos has a right under the MEPA (the mining agreement between Oxiana and the Government of Laos) to acquire 10% of the Sepon project at historical expenditures. In 2005 the Government indicated its intention to exercise that option and will fund its 10% interest through foregoing dividends. This is anticipated to occur in 2006.
Gold and copper deposits discovered in the Sepon district now contain an estimated 3.8 million ounces of gold and 1.7 million tonnes of contained copper and exploration by Oxiana continues to increase these Resources.
Oxiana has been producing gold at Sepon since December 2002 and copper since early 2005. In 2007 the Sepon operations produced 102,390oz of gold and 62,541 tonnes of copper and studies are underway to significantly expand both gold and copper production.
In December 2007 Oxiana's Board approved an expansion of the Sepon Copper operation from 60,000t/a nameplate capacity to 80,000t/a by 2010.

Golden Grove
Golden Grove is a world class massive sulphide base and precious metals operation, employing over 800 staff and contractors.
The plant at Golden Grove was first built in 1990, and was acquired by Oxiana, from Newmont Mining Corporation, in July 2005.
Golden Grove consists of the Scuddles and Gossan Hill zinc and copper underground mines and the Scuddles concentrator.
Golden Grove has been in continuous operation since 1990 when production began at Scuddles. Gossan Hill was mined from mid 1998, at the same time the treatment plant at Scuddles was expanded from 0.9Mt/a to 1.2Mt/a. Scuddles was put on care and maintenance in July 2005. The Scuddles mine was reopened in mid 2007 and production commenced on a limited scale.
The Gossan Hill deposits contain zinc and copper massive sulphide mineralisation and also contain associated silver, gold and lead mineralisation.
Mining and Processing
The mining method at Golden Grove is sublevel open stoping for the primary zinc orebody. Ore from the Gossan Hill mine is trucked to the surface where it is crushed and delivered to the mill via a 3km overland conveyor. The ore is treated via a two stage grinding circuit followed by floatation using air agitation to separate the sulphides.
Production
In 2007 mill throughput for the year reached record levels due to commencement of certain mill improvement projects. In 2007 Golden Grove produced 131,954t of zinc, 15,404t of copper, 48,807oz of gold, 3,165,408oz silver and 8,119t of lead.
Production (contained metal in concentrate) for 2008 is planned to be 135,000t to 145,000t zinc, 20,000t to 25,000t of copper, 50,000oz to 55,000oz gold, 3,000,000oz to 3,500,000oz of silver and 10,000t to 13,000t of lead.
Future Developments
In 2007 significant discoveries were made at Golden Grove, which highlights the potential for further additions to mine life and annual capacity.
Expansion studies are currently being conducted at Golden Grove to investigate the addition of open-pit mining and possible extensions of the underground mine. These studies aim to increase mine life to beyond 2020.
Exploration and Development
Oxiana is currently constructing the Prominent Hill copper-gold mine in South Australia and the Martabe gold project in Indonesia is also being advanced.
