IF the frequent comings and goings of Freeport McMoRan Copper & Gold’s big boss, James R. Moffett, is any indication, negotiations between the Phoenix, Arizona-based mining giant and the Indonesian government over the contract of work extension continue to be tough going. The stakes are high for both parties. For Freeport, it’s the 2.27 billion tons in reserves it wants to continue mining in the central highlands of Papua. For Indonesia, it’s an additional US$18 billion in new investment and a bigger share of the revenues. But is it just dollars and cents, or is politics a major hang-up as well?
