They're using the different fluxes and collectors to find the optimal method but it all sounds a bit "past tense". If they're rolling out an assay method in a few weeks you'd think they'd be onto the method they're using by now.

Of course it's a complex ore but they already have a variety of methods that extract the metals (pyromet, hydromet.). They're just sussing out which method is best.

One big box almost ticked. The assay results will reveal the true grades of these monster deposits. Bring it on!
