Each the 2021 and 2020 useful resource estimates have been accomplished utilizing the identical methodology, parameters and metals costs ($1.20/lb. zinc, $2.50/lb. copper, $1/lb. lead, $16/oz. silver, and $1,200/oz. gold utilizing a 7% base case cutoff grade of seven% zinc-equivalent.
Wolfden is happy with the regular progress and enhance in assets with out altering what are conservative metals value assumptions, mentioned president and CEO Ron Little in a launch. “The mission continues to reveal its potential to be a major financial driver in a area that has seen little improvement and job creation within the final decade,” he added.

The after-tax financial evaluation features a web current worth with an 8% low cost of $198.3 million and an inner fee of return of 37%. The payback interval could be 2.4 years. If the NPV got a 5% low cost fee, it could be $255.5 million.
