GREAT QUESTION.  LIKELY not before 2030, BUT not to worry.  Coper CRUNCH is going to be sever.  Coper shortages will ravvage the lo copper prices, in fact that is happening now.  When COPER hits $12.00 USD per pound, on its way there now.  RE-cal that demand and price rise have a way of getting priorities in order.  MONEY INFLUX will have BIG MACK Bulldozers out there digging into the Ore pits and the money supply by demand, EVs and re building the POWER GRID, think I am lieing,,,,,,,THINK "TEXAS LAST FEW DAYS",,,,,,,this can never be allowed to happen agin.  Stack the chips and the pile falls over and the chips are scattered all over the FLOOR, you've got a MESS,so the answer is with the crush of EVs,BANK that COPPER WILL HAVE EXORBATANT DEMANDS to be met from the ORE pits,,,where there is a will there is a way,,,,,where there is copper,they will dig(MINE).   Take a break it will happen all by itself, real soon.
