I asked, @NorthMinCorp, a zinc/copper explorer-developer with a brownfield exploration project in Ireland, whether metallurgy was a challenge for the previous operators, given that the residual grades they’re looking to reprocess from the tailings only exist because those metals couldn’t be recovered from the oxidised ore. When previous operators leave metal in the ground or in tailings because of recovery problems, it could mean that metallurgy was a constraint. Understanding those historical challenges is important as it can help assess whether the current team has a better process, better technology, or a different approach that can actually recover what was left behind. What else could/should I have asked $NMB.V?
