I think you are mixing up some USD and CAD figures. Might be easier to remain in USD. From the previous update we had, I'd remain with 5 years to build the mine. If the availability is 92%, I suppose we should also consider this.
Let's assume a production of:
- 335Mlbs of CuEq LOM
- 400Mlbs of CuEq (Y1 to 7)
- 300M lbs of CuEq (Y8 to 14)
Calculations:
- Revenues (Y1 to 7): 400M x 3.15 = 1260M
- Processing: 133ktpd x 365 x 8.66 x 92% = 387M
- Sustaining: (755M / (350Mlbs x 21 years)) x 350M = 35M
- Cash flow: US$838 per year
- Revenues (Y8 to 21): 300M x 3.15 = 945M
- Processing: 133ktpd x 365 x 8.66 x 92% = 387M
- Sustaining: (755M / (350Mlbs x 21 years)) x 350M = 35M
- Cash flow: US$523 per year
Gives me roughly a pre-tax NPV (8%) around US$2.5B and 30% IRR, which I feel is conservative.
IMO.
