Mining and materials
Copper Ore
Copper Ore is an early mine resource used for bars and workshop builds.
Abandoned Ruins #1, entered from the ruins entrance near the Research Center.
Repeat on later weekly passes as needed; the pass limits access, but the resource farm is ongoing.
Stop once you have enough Copper Ore for the next planned build or bar batch, then switch to another workshop bottleneck.
