For me, 2023 is absolutely unrealistic. The industrial area does not have electricity, water, sewage or connecting roads yet, the land has not been allocated. The construction of the factory has not even begun. If they start early next year, it will be 2024 in no time. MT must have a plan for that, as he did with Swerim.
I think the announcement is good, it shows that they are getting the maximum out of it. Only this time not too much, so they don't have to tip it back.)
The resource can probably be developed relatively quickly. And in the first processing steps can be improvised if necessary.
