The unique thing about MIN So you point out that lots of other miners will be very profitable at $4 copper too.
True, but MIN is very profitable at even $2 copper.
This makes MIN a standout because it reduces risk to just about zero. Copper prices will rise and fall, but MIN can go full steam ahead in any market, and fully benefit from higher prices. Many miners will lose money at $2 copper, and have to try desperate moves to survive.
This stability makes MIN a far superior investment compared to most other copper miners.
