Using pretty pictures can lead punters to dangerous conclusions.
If you look at the core photo and take the reasonable assumption that this is probably the best bit, my guess is that the bit selected is no more than 3% chalcopyrite=around 1.0% copper (probably a lot less!).And this would naturally be selected as the best bit.
Then add back location costs which would be enormous for this neck of the woods.
Then note BHP walked from the area.
Looks to me like a nice little technical success but very early days as to anything remotely commercial.
Better opportunities elsewhere in my opinion but that does not mean you cannot have fun trading them in the meantime.
