enoch the roadmap is that narrow vein nugetty quartz reef can be mined very successfully and profitably by selective mining techniques, SLR has shown that. As Robert points out you dont necessarily need a decline to do it.

The Daisy Milano mined grade was around 29gpt before the decline was put down, similar to Morning Star. That was on low tonnages, probably around 5000 to 6000 tpa. The mined grade is now around 12 gpt.Even with selective mining higher tonnage will always result in dilution

I believe if MCO was to start operations hoisting 15000 to 20000 tpa mined grades close to the historic are possible, over 20gpt. , depending on the endowment of the reefs they mine. They are targeting 150,000 tpa which is what SLR are doing now, so one would expect grades more like 12gpt at that point.
