The deeper holes do validate the broad model. This is two exceptionally big copper systems: extensive shallow copper and growing and extensive deeper ore very likely to be made viable and delineated by the income from early mining of shallow open cut concentrate 53% cu under relatively simple operating conditions.

To put it in perspective Escondida's ore is now running at an average grade of around 0.5%-0.6% and while still economic because of the scale of the earth movement, crushing and simpler leaching used, costs in Chile are rising as grade is falling. There is a drought which continues. There is absolutely no doubt that the Storm prospect is now a stand out globally. as global grades decline, costs rise and sovereign risk becomes a greater concern. Oz Minerals adds just 7% to BHP's copper output and Carrapateena starts at about 600m below surface. There is value here.
