CUU own 25% Schaft Creek: proven/probable min. reserves/940.8m tonnes = 0.27% copper, 0.19 g/t gold, 0.018% moly and 1.72 g/t silver containing: 5.6b lbs copper, 5.8m ounces gold, 363.5m lbs moly and 51.7m ounces silver; (Recoverable CuEq 0.46%)
MoneyK, I was wondering if you would teach me how you did your NPV calculations.
I have made an attempt below but there a few things where I don't know where to plug them in.
Step 1. Calculate the Cash Flow per Year: using your prices: Copper $3.15; Gold $1,300; Silver $17.50; and Molydebum $10.00.
I don't know where to plug in the Sustaining cost of $1B?

Sustaining Costs ($1 B over 21 years) | $47,619,048 | |
Cash flow: Years 8-21 | $995,375,108 | |
Step 2: Calculate the NPV.
I plugged in the numbers - the first 4 years I avaraged the $2.8B construction costs.
But I'm off your calculation of $4.7B NPV. Where have i gone wrong?
