Just one point (I am attempting to confirm this), I believe the opex (cash costs) will be around $400/oz.
I believe ADU is around US$400/oz although they currently have a larger jorc resource. If SBL do as is now indicated as I believe they will, then I would expect close to the same cash costs.
Regardless you are right, they will have a significant free cash flow at current Au prices.
SBL will definitely not remain at 28M MC for much longer. This is a very real short to medium term multibagger in the waiting. A real gem.
