Valuing HCH, page-36

You won't get anywhere near production without a scoping study, pre-feasibility study, bankable feasibility study. They may decide to skip the PFS if the scoping study is detailed enough with enough confidence built into the resource model. All three will take 2 years, and the BFS won't be bankable unless the resource is properly defined. Then you'll get your reserve estimate.
Production is a looonnnngggggg way away, you're setting yourself up for disappointment if you believe otherwise. The focus for now is exactly where it needs to be - resource definition & upgrading from inferred to indicated, to take that to the consultants and get a PFS/BFS done.

I believe they are redesigning the stopes in Productera to target high grade which will take advantage of the Copper bull market.
