Hi Damers,
Given the Grasberg news last week, I found myself researching block caves some more. Watched a FCX video on Grasberg - WOW. Blew my mind the scale of the operation.
I know Grasberg has an open pit and 3 block caves, compared to the single block cave initially planned at Alpala (with potential for far more).
What really surprised me is metals comparisons:
Cascabel - 12.4Mt Cu, 31.3 Moz Au, 26.8Moz Ag
Grasberg - 14.0Mt Cu, 26.3 Moz Au, 121.3Moz Ag (Source, Wikipedia & 2022 FCX annual report)
Really shows how massive Cascabel is.
Cascabel will be as important for Ecuador as Grasberg is for Indonesia. $billions and $billions.
