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.

The Easy Copper is Gone In this note, I look at the relationship between copper discoveries and implied costs since 1990, plus the key implications for investors. This is part 3 of my “Supply stress” series on copper.
