[HMGM] Ep.21: "The Santiago Mill: full (and final?) tour of the abandoned 1930s flotation gold mill"

"How to Model a Gold Mill in 27,000 Easy Steps" (HMGM)
Episode 21: The Santiago Mill: full tour

Series Description:
Are you curious how mere ounces of useful stuff can be extracted from many tons of ore? We were, and are exploring the technology of the gold milling process. Join us as we build a 1:20 scale model of the historic Santiago Mill, which still stands at 12,200 feet in the Colorado Rocky Mountains southwest of Georgetown, and learn about mining technology and Colorado history along the way.

Episode Description:
[21] The full tour of the Santiago Mill! We unexpectedly found the mill open some time ago, and recorded a full video tour before it is permanently converted to a historical interpretive site with restricted access. The jaw crusher, ball mill, rake classifier, flotation cells, shaker table, and concentrate bins are generally intact.
