The Harmill was being operated by Gerald B. Hartley, Sr. and was worked through the 1930s. (Gerald B. Hartley, Jr. Collection) There was an inscription on the image. "The Montezuma district was laid out after the discovery of ore in the area on May 24, 1867 by Thomas Nagle, Mat Plunkett, and a Mr. Carlyle. The district was active through the 1880s after which mining came to a standstill. Montezuma experienced a revival in the early 1900s on the heels of the Goldfield boom. Mining continued through the 1930s from operations such as the Harmill. Ore was chiefly silver accompanied by lead with some gold. Recorded production from the district was over $500,000."
