Freeport-McMoRan Inc said on Wednesday it expects to "imminently" sign an agreement with Indonesia that would enable it to immediately resume copper concentrate exports which have been halted for more than six months. Freeport said on July 8 it had agreed on a draft memorandum of understanding but had not signed it. At the time, it gave no time frame on when it would resume exports. Indonesia introduced a mineral ore export ban and a steep export tax in January. The gold and copper miner also reported second-quarter results on Wednesday that were little changed from a year-ago. "It is a compromise to create a bridge for us so that we can return to normal operations," Chief Executive Richard Adkerson said of the MoU on a call with analysts and investors.
