You're assuming they wanted to truck Tampia ore which I'm not because it never made much sense to me(providing it keeps adding oz's ) and RMS don't make choices that aren't based on best economics .I think it fell over because scale of Mace didn't look to provide enough oz's to justify the 5c .
By the way I'm sceptical about a payback period of 18 months .
Don't mistake me , I think Tampia seems a good project just EXU management seem to overstate and posters here seem to believe it all .
For example I believe expectations for Mace were unrealistic .
Companies don't normally build mills on half a mill oz reserve (which you really should be aware of) .
Tampia needs to be drilled out further and I'm sure it will .
