espite very high nominal prices, miners of all types remain very weak. Under the very right and rare circumstances, metals are easy and inputs are cheap.
That doesn't happen in a correlated+QE environment. Labor and oil rise with the metals (or soy or corn) and destroy the margin.
Today ores are weak and most good $$ sources of metal are byproducts or old workings, tailings. Humans have been picking this pile for 20,000y.
Exotics, like flourspar, salts, bulks, ti02. whites and REE are all stuck in a rut.
Only a real, organic global boom will push true demand.
