The 65 ktpd mill expansion, including the integration of New Ingerbelle, brings Copper Mountain Mine's after-tax NPV at an 8% discount to US$1.0 billion. (Per the November 2020 Technical Report). Further potential exists through the upgrading of resources to reserves and further exploration to continue to extend the mine life and add value.

As a result, the copper and gold net smelter returns for copper concentrate sold to Smelter A are equal to $511 and $515 per tonne of concentrate, or $48.01 and $48.37 per tonne of ore. When these numbers are divided by the mill feed grade, the copper and gold NSR factors are equal to $20.69 per % Cu and $18.97 per gram of gold.

Recovery rate is not the most important factor in a production mill setup. When I ran a circle blade we would saw a lot of 12 to 14 inch logs into cross ties and get 4 boards off the sides. My band mill does no better other than the fact that I can take a bit more time and often get a better board and trim a bit better.
