Took a look at the early October filing by EWC for their annual report to shareholders. 135 pages and nary a mention of IOC, or PNG. Sure makes it appear that the Bigs have arrived in PNG and they are very hungry. Ewc has good things going on in Australia, Indon and Philippines, PNG for now appears out of their league.
