I'm not 100% sure. I think the uranium got emplaced in a roll front by mild sulphuric acidic conditions over time but I think the the recovery of Uranium from the rock is based on the redox potential in mV or V that can be generated by the lixivant after conditioning (acid or base). They have done tests on representative samples in the reserve. It's possible that some parts of the resource will be more alkaline and thus require more acid or peroxide conditioner. I think it just comes down to $ or an economic balance, a combination of level of acidification in well field pattern selected. I think testing at MUA1 has shown if they keep the pattern tight and don't have the solution percolating all over the place you can get dissolution of 67mg/l which is sufficient for recovery.

Management are aware of the issue acid consumption. In fact Wayne Heili was gloating to me that they would benefit from low sulphuric acid prices a couple of years ago. At an AISC of $42/ lb for U they can afford a bit of acid to generate the redox potential required for leaching.

That's just what I think I'm not an expert. My experience comes more from the combination of metallurgy plus the bit of geology training I've had. (I wasn't bad at chemistry).

Please don't ask me any more scary questions I'm charry enough.
