This is an early beta version that’s still a work in progress. We hope to develop and refine the contents going forward. In the meantime, we’re making it fully available to the public as-is. Started by the Jefferson County Historical Commission in the 1990s, it was transferred to the Golden History Museum-City of Golden in 2020.

|History||The malachite vein containing copper was first discovered in 1866 and was periodically worked until 1917. Piles of timber, tailings, and a huge rusted, metal boiler remain at the site. Remnants of several crude buildings are also visible. The boiler provided energy to operate a crusher to produce sludge that was transported to smelters in Golden. Resident Stanley Thiede says his father worked at the F.M.& D. in 1904 and again in 1917.|
