As surface tin resources faded, tinners dug deeper following the lodes—the near-vertical sheets in the rock in which tin ore and other metals are found in Cornwall. The challenges of hard-rock mining and draining water from shafts spurred skills, innovations, and machinery that would be exported around the world.
