Like many other global mining companies, Freeport is staking much of its future copper growth on developing new mines in Peru. Action taken by Humala's government to raise taxes and squeeze miners' profits could, therefore, curtail foreign investment in Peruvian mining projects and reduce future copper supply, analysts say.
