Freeport-McMoRan Copper & Gold Inc.’s environmental management programs encompass all aspects of our operations, not just those related to mining. We have a comprehensive waste management system using the principles of reuse, recycling and reduction. Our waste minimization programs involve waste reduction and substitution with environmentally friendly products. Bulk containers and used oil, paper and tires are all reused to the maximum extent possible. Other recyclable materials – such as aluminum, scrap metals and used batteries – are collected and stored in a temporary storage area for subsequent recycling or removal in accordance with local government requirements.

Wastes, including small amounts of hazardous waste, are segregated at the point of origin. Collection, packaging and storage of hazardous wastes generated by assay work on ore samples, analytical laboratories and other processes are managed in compliance with local, provincial and national regulations.

Hazardous wastes are segregated and stored in specifically designed storage facilities until they can be shipped to approved offsite hazardous waste disposal facilities. Medical wastes are separated from other wastes in special containers for final destruction offsite.

In addition to compliance with all applicable laws, rules, regulations and standards, the following specific activities are mandatory to meet corporate requirements:

• Inventory and characterization of waste streams
• Waste storage and labeling
• Material disposal facility evaluation
