The next year, the company sold out to a London syndicate for $500,000, which retained the name of the mine, remodeled the mill, and began aggressive development. The circa 1890 Modoc Mill is a good example of industrial architecture associated with Boulder County's mining history. This concentration mill of wood and metal reaches four stories in height. The uppermost story of hewn logs received the ore. Here gravity bins held the ore until it was fed into a crusher and the stamping apparatus below.
