Hi,
Real progress not hype. Value measured in resources improving.

I like the pressure oxidation metallurgy because the reagent used is oxygen, made on site with oxygen generators which consume electricity.
Oxygen generators readily available for rent or lease.
The sulfide concentrate produced by flotation is oxidised to produce water soluble sulfates . Pure metals can be electro-won from sulfates.
No nasty chemical inputs like cyanide, and if powered by solar electricity, green and sustainable.
Note I am NOT a metallurgist, and invite correction or addition to this story.
