While the scope 1 analysis is underway, Osisko will also launch several trade-off studies to identify potential alternative energy sources to hydro. These include natural gas-fired generation, wind power and geothermal energy.
Osisko drill programs have outlined an indicated resource of 12.9 million tonnes grading 4.6% zinc and 1.7% lead. The inferred portion is 37.9 million tonnes at 4.9% zinc and 1.9% lead. Osisko’s drilling this year in the East Mill zone extended mineralization between separate open pits and increased tonnage by 13%.
