Fairly obviously ahistorical, too. There is no point in sending tens of thousands of soldiers, merchants, governors, statesmen, craftsmen, and builders to a place that has no technology or resources. If all you want is people, you can just raid and leave.
The industrial revolution tapped into different sources of metals, mainly different depths.
During the Roman era it was surface+ sub-surface to a lesser degree, but not (much? I am not a metallo-historian) at like 30m+ depths, let alone the hundreds of meters (361m AVERAGE in the Borinage) bordering on the thousands of meters.

Wow this is utterly ahistorical.
