Could RIO JV be close to getting going?From the recent quarterly-

"Rio Tinto Exploration have entered into an agreement with UTS Geophysics to conduct an airborne geophysical survey over the Hillalong project area in Queensland. This agreement covers the flying and data processing of high resolution fixed-wing airborne magnetic data. The objectives of the survey are to assist with the interpretation of continuity and structural features of the target coal seams in the Hillalong Project.
During the quarter Rio Tinto Exploration Pty Ltd continued site access activities and initial off-site preparation for drilling. First entry to EPC 1824 and results of exploration activity carried out by Rio Tinto Exploration Pty Ltd will be reported in due course."

The value of this JV while undisclosed in monetary terms would have to be multiple of current market cap me thinks.
