The Project is situated on the boundaries of four provinces: South Cotabato, Sarangani, Sultan Kudarat and Davao del Sur, and represents one of the world’s largest undeveloped copper-gold deposits. The Tampakan Project is a 2. 4 billion metric ton deposit, containing 13. 5 million metric tons of copper and 15. 8 million ounces of gold at a 0. 3 % cut-off grade. The Project is operated by Philippine-based affiliate Sagittarius Mines, Inc. (SMI), whose 40% controlling equity is a joint venture between Xstrata Copper (62. 5%) and Indophil Resources NL (37. %). The 60% non-controlling equity shareholders of SMI are the Tampakan Mining Corporation and Southcot Mining Corporation (known as the Tampakan Group of Companies). SMI submitted the Mining Project Feasibility Study for the Tampakan Project to the Philippine government in April 2010 and is progressing with the Mine and Off-site Environmental Impact Assessments (EIAs). SMI expects to submit the Mine Environmental Impact Statement (EIS) to the government by the second half of 2011. In December 2010, the Project employed 372 employees and 1,185 contractors.

The strong recovery in global demand for copper in 2010, together with robust copper prices, enabled Xstrata Copper to finish the year with a solid set of operational and financial results. The business was well positioned to take advantage of these favorable economic conditions as a result of the actions taken by our management teams during 2009 in response to the global financial crisis, including prudent cost reductions in the context of an unwavering focus on sustainable development and on our growth strategy.

Xstrata Copper’s commitment to sustainable development remained firm in 2010 and was reflected in the 22 national and regional awards presented to our sites during the year for excellence in this field. At the Group level, Xstrata retained its position as Mining Sector Leader on the Dow Jones Sustainability Index in 2010/11, for the fourth consecutive year, and was named as the Super Sector Leader for basic Resources industries. As part of the Xstrata Group, the principles of sustainable development are integral to our business model and guide our daily decision-making.

We take a systematic approach to setting targets, monitoring performance and reporting, both internally and externally, against our sustainable development policy, standards and targets. Throughout the year, our sustainable development performance was closely monitored and evaluated by the Xstrata Copper Sustainable Development Committee. Our sites also participated in a range of internal and external audits to provide assurance against the sustainability standards of Xstrata Copper and those of the Xstrata Group.

Following an annual review of our management policies, we launched an integrated Xstrata Copper Sustainable Development Policy in May which: strengthened our published position on human rights; improved the alignment between the policy objectives of the Xstrata Group, Xstrata Copper and our operations; and simplified our overall sustainable development framework. Due to the significant advancement of our project development pipeline, in early 2010 Xstrata Copper restructured the organization of our project development activities to capitalize on our regional synergies in South America and Asia Pacific.

Under the new structure, Executive General Manager – Project Development South America, bob Drabik, assumed responsibility for the development our Antapaccay, Las bambas and El Pachon projects in Peru and Argentina. As Executive General Manager- Project Development Asia Pacific, I retained responsibility for the Tampakan project in the Philippines and Frieda River project in Papua New Guinea. Our Asia Pacific projects made significant progress in 2010, achieving a number of important milestones. In April, the Tampakan project submitted its Mining Project Feasibility Study to the Philippine government.

The project also completed its mine site Environmental Impact Assessment (EIA) in December, for public consultation and submission during 2011. In addition, the project commenced the EIA process for its offsite infrastructure, including the port, power station, filter plant, transmission lines and pipelines, in the second half of the year. The Frieda River project delivered its pre-feasibility study in October 2010 and commenced a drilling program and technical studies for a feasibility study which is TAMPAKAN PROJECT scheduled for completion in January 2012. The project also continued to undertake extensive environmental baseline studies and stakeholder engagement activities for its ESIA which is scheduled for completion in 2011. The health and well-being of our employees, contractors and visitors continued to be a key priority for the Asia Pacific projects throughout the year. In 2010, the projects achieved their Lost Time Injury Frequency Rate (LTIFR) target of
