There was a small operation in the early days of the mining operation that was on the northern side of Mount Lyell, known as the Comstock mine. In the late twentieth century, just west of the Comstock workings was a section of the mine known as Cape Horn. The western end of the mountain has been named Cape Horn Spur, as the Mount Lyell Mining and Railway Company had a mine called Cape Horn in the 1970s at the west end of this spur.
