Robert Friedland(@robert_ivanhoe):This is a great chart… We are fortunate that our geologists at @IvanhoeMines_ are discovering copper in the Western Forelands Shelf, on the western edge of the DRC Copperbelt, at a cost of less than $10 per tonne of copper discovered... which is over two orders of magnitude cheaper than today’s average implied discovery cost, accounting to this chart.
