" no one has been able to do it."
I did have a look over the info on PNA but the complication is (if I remember correctly)that the production by PNA is really of copper (if I remember correctly) with gold as an additional mineral.

So, in my opinion it is a bit hard to compare RAU and PNA because they are nto dealing in exactly the same thing.

At least that was my gut reaction on a quick perusal of the information
