Notes to Editors

Avocet Mining PLC ("Avocet" or "the Company") is a gold mining company listed on the AIM market of the London Stock Exchange (Ticker: AVM.L) and the Oslo Børs (Ticker: AVM.OL). The Company's principal activities are gold mining and exploration in Burkina Faso (as 90 per cent owner of the Inata gold mine), Malaysia (as 100 per cent owner of the Penjom gold mine, the country's largest gold producer) and Indonesia as 80 per cent owner of the North Lanut gold mine and Bakan project in North Sulawesi).

The Company recently announced that it had initiated exploration within the Inata mining licence area and in the surrounding Bélahouro district with the objective of significantly increasing Inata's resource and reserve base as well as investigating the highly prospective Souma Trend, located 20 km from the Inata mill. The Company has a number of other advanced exploration projects in West Africa and South East Asia.

Background to operations

Inata has a resource of 1.7 million ounces and reserves of 932,000 ounces. Inata poured first gold in December 2009 and has now reached a production rate in excess of 11,000 ounces per month. Other assets in West Africa include exploration licences in Burkina Faso, Guinea and Mali (the most advanced being the Tri-K gold exploration project in Guinea with a resource of 666,500 ounces).

Penjom is Malaysia's largest gold mine and was developed by Avocet in an area of historic alluvial mining. The mine is located in Pahang State, approximately 120 km north of the country's capital, Kuala Lumpur.

North Lanut in North Sulawesi, Indonesia, was developed by Avocet from the exploration stage and has produced over 270,000 ounces since it was commissioned in 2004. North Lanut is located within a Contract of Work which includes exploration and mining rights over approximately 50,000 hectares in an area highly prospective for gold. Avocet holds an 80 per cent interest and an Indonesian company, PT Lebong Tandai, owns the remaining 20 per cent.
