We’ve got a special technical chat for the Money Miners with Rob “Refractory” Ryan coming onboard.
We run through all the ins and outs of what refractory ore is, what it means for a project, how investors should think about it, what it does to the capex & opex, plus a bunch of real world operations that’ve had to deal with this type of mineralisation.
