## Making a Commitment 

Comprehensive monitoring and scientific study, compliance with international standards, and commitment to reclamation and revegetation highlight a mission of environmental responsibility. 

Environmental Management We are committed to minim izing the impact of our operations on the sur- roundi ng environment and to reclaiming or revegetating affect ed land. Through our comprehensive Environmental Policy, we commit to sound environmental management and pr actices, to providing adequate resources to fulfill our re sponsibility, to comprehensive monitoring to assess our eff ectiveness and to continuous improvement of our pe rformance. This policy is available on our web site (www. fcx.com). 

## Highli g hts 

• PT F reeport Indonesia does not use mercury or cyanide in its processes, relying instead on a flotation process that physically separates the copper- and gold-bearing min erals from the ore. Comprehensive monitoring con- duct ed for years continues to show there is no signifi- cant level of mercury, arsenic or cyanide in the water, sedi ment, fish or plants in our operations area. 

• For 2004, our comprehensive long-term monitoring prog ram included the collection of approximately 7,200 envi ronmental samples and almost 50,000 analyses, whic h included aquatic biology, aquatic tissue, plant tissu e, mine water, surface water, ground water, sani- tary wastewater, river sediments and tailings, the finely gro und natural rock residue from our milling process.

• Sampling in 2004 continued to demonstrate that th e water in the river that transports the tailings from t he highlands meets the Indonesian and U.S. Environme ntal Protection Agency drinking water standards for dissolved metals. 

• Data from biological sampling continued to show th at the estuaries downstream of the tailings deposition area are functioning ecosystems based both on the number of species and the number of specimens collected of nektonic, or free-swimming, organis ms such as fish and shrimp. 

• Comprehensive, ongoing scientific studies on land r ec- lamation and revegetation in both the highlands an d
