Since July. Remember the Chloride Copper Mine is a pre-existing mine. The main permits are "Good for the life of the mine" but require updating and a transfer from the previous mine owners to SIRG. And you are correct - it can take many years to get a NEW mine permitted.

The local newspaper produced an article on SIRG's progress at the mine.

The environmental assessment allows Sierra to propose mitigation of significant environmental effects to less-than-significant levels. The proposal will be based on what's been outlined in the MPO. Todd expects Sierra to have a complete environmental assessment to present to the community for comment no later than mid-February.
