Given it takes 14/18/33 days (take your pick) to extract when it's been crushed and then pulverised in a ball mill and given the complex nature of the ore, we don't know if it's amenable to traditional Heap Leach as of yet.

From my observation, even the 33 day leach was done after being crushed and milled so that would lead one to think Heap Leach in the traditional sense could take many months, if it's even possible at all - not to say they won't try it though.
