Copper production was very demanding of transport: of coal inwards to fuel the engines, and of the ore outwards to the refining plant. In both cases this traffic was from and to South Wales, and the coastal shipping route was round Land's End, a difficult and dangerous passage.
Copper production necessitated substantial movement of materials: coal was transported into the engines, and ore was moved from the plant to the refining facility. This traffic connected South Wales with the challenging passage around Land's End.
