Re Nimbus the thinking last year was about revenue from the 3 precious metals ,the thought was to build a special plant to crush ,grind, floatation ,to produce concentrates and then direct shipping of the concentrate at much lower capex and opex..
Estimate for this type of plant was A$30-40M at the time ,but would make sense to have gold plant there first so power ,water and infrastructure cost could be shared.
JP thought that a silver price of A$45-50 would make the project fly , but now maybe todays Zinc price will have more of an influence.
