Looking at the Josemaria FS, it does actually look bigger than Bushranger to me - depending how we view Ascot. If you take Measured + Indicated + Inferred, the contained copper is 4.7Mt at 0.1% cut-off. There's a table that shows this amount reduces only marginally at 0.2% cut-off. In addition there's a lot of gold (10.1m ozs) and silver (52.1m ozs). At current market prices the copper equates to 70% of the total value. If you convert the gold and silver market values to copper then (very crudely!) the mine could be considered to be a 6.7Mt copper mine.
Against this, it looks very heavy on capex - $3.0bn initial, including a 250km road and power line. As a non-expert, recoveries also look lowish - 85% copper, 65% gold, 72% silver. It's almost all sulphide material, suggesting higher opex? So the amount of metals might be substantially offset by the cost of extraction - possibly.......
