Brisbane, 2 April 2007

Xstrata Copper announces that it has completed its option exercise over the majority interest and assumed management control of the Tampakan copper-gold project in the Philippines through its Philippines subsidiary, Sagittarius Mines, Inc. (SMI). This represents a significant increase in the company’s involvement in the Tampakan project, including the appointment of several senior Xstrata Copper executives to the SMI Board and Management..

Xstrata Copper exercised its option to acquire 62.5% of the controlling interest in the Tampakan project on 21 December 2006, and assumed management control from ASX-listed company Indophil Resources NL (IRN) on 30 March 2007, following completion of the option agreement.

The Tampakan project will continue to be managed from the Philippines through SMI.

Xstrata Copper has appointed several new directors to the Board of Sagittarius Mines, Inc. effective 30 March 2007. The appointments include Charlie Sartain as Chairman of the Board, Peter Forrestal as SMI President, and Louis Irvine, Neal O’Connor, Florido Casuela and Lucas Nunag as non-executive Directors. The nominees will join existing Board members Tony Robbins, Paul Dominguez, Mario Jalandoni, Gerry Palermo and Rogelio Flores.

“The changes to the Board come as the Tampakan project embarks on a comprehensive feasibility study phase. The new Directors will broaden the expertise and experience on the Board and play an important role in guiding the project at this key stage of its development,” said Mr Sartain.

“On behalf of Xstrata Copper and SMI, I would particularly like to thank Paul Dominguez for the important leadership role he has played as SMI President for the past two years, as well as Tony Robbins, Managing Director of Indophil who with his team have made a vital contribution to advance the Project to this point.� I would also like to acknowledge the contributions of retiring Board members, John Madden, Paz Somera, Roy Antonio and Alan Buenavista. Under the guidance of the previous Board and Management, SMI has built and maintained close working relationships with the Philippine government and local communities and progressed important evaluation work on the project,” he said.

“The mineral resource estimates at the deposit indicate the project has excellent potential to become a new long life asset for Xstrata Copper. Our focus now is on feasibility-related studies, which we aim to complete by the end of 2008, and on progressing sustainable development programs with local communities.

“Xstrata Copper has a strong reputation internationally for community engagement, social responsibility, health and safety management and environmental performance. We will continue to build on the good work SMI has done with the local communities, especially in the areas of education, health, community infrastructure and other sustainable development projects.

“Xstrata Copper is committed to working with all levels of government, the community and its partners in Tampakan as the project progresses into the important feasibility study phase,” he said.
