Its still an open question as to what eventual recoveries will be as they have yet to complete test-work on the sulphide component of the native copper ore. That comprises 22% of the Cu value and a significant amount of Co, so important that they get a good result for that. Other questions are what proportion of the deposit each type of ore comprises, and whether similar recoveries would be expected when treating lower grade material.

Still IMO they've done well with the metallurgy. Already its a significant improvement over others with native Cu ores (e.g. AOH) who struggled to get a 70% recovery.
