摘要

The cost curve below plots the projected cash operating costs of 23 active copper projects, currently in the feasibility or preproduction stages of development, against each mine's percentage of the group's total potential production. The projects represent 1.7 million mt of annual copper production capacity, which would amount to a 12.6 percent increase in world copper production in the unlikely event that they all reached capacity in the next few years. The cost information is from a variety of sources, and in some cases is based on previous feasibility or prefeasibility work that is currently being updated. The weighted average cash cost for the included group is 0.45 dollars/lb, but this might be overly influenced by the lowest projected cost--0.28 dollars/lb previously estimated for 250,000 mt/y of copper at what is now Noranda's ElPachon project in Bolivia. In March 2004, Noranda reported plans to update its El Pachon feasibility study by the end of the year, including a revised mining plan, infrastructure review, costing, and readjustments to find the optimum processing rates to get more copper at a lower investment than that estimated by previous owners, Cambior and Minera San Jose. The results will help Noranda decide the future of the project.
