Mining and timber
Coal and Stone
Coal supports smelting while stone supports construction, so collecting both can keep separate workshop needs supplied.
Quarry stone piles and underground mine deposits north of the homestead.
Gathering can be repeated as accessible resources allow; route access and deposits are tied to progression.
Stop when you have enough fuel for the planned smelting and enough stone for the next build; switch to the depleted material later.
