The mill in the center of the above photograph, is the main mill for the Holden Lixivation Works. The building in the lower center is the refinery, where the processed ore was removed from the sodium cyanide, bagged and shipped to a smelter, much like the Aspen Smelting Company, located across Castle Creek. The building to the right of the smokestack is the Sampling House. This building is still standing and houses the diorama today.
