Copper mining town

Johnson

A copper camp on the east side of the Little Dragoon Mountains that held nearly 1,000 people in 1925 and lost its post office in 1929. Open pits later covered the townsite, and the Johnson Camp Mine started producing copper again in 2025.

Active mine · no access

The Johnson townsite is inside the Johnson Camp Mine, where Gunnison Copper started leaching copper in July 2025. It is private, working mine property. An undated listing reports that mining has destroyed the old ruins, leaving only foundations. There is nothing to visit. Don't drive past gates or posted signs.

Overview

A copper town under its own tailings

Johnson sat on the east side of the Little Dragoon Mountains, about 65 miles east of Tucson and a few miles north of today's I-10. Mining here began around 1881, when the Peabody, Republic and Mammoth claims started a camp called Russellville. It peaked at about 100 people. In 1883 the smelter moved to the Peabody Mine, and Johnson grew up half a mile from it as the Peabody company's headquarters. The camp was named for George J. Johnson, general manager of the Cochise Copper Company, according to the Arizona Daily Star.

Johnson got a post office in 1900 and had 317 people by 1902. Smelters and new shafts followed, and by around 1917 the town had a pool hall, a one-room school, stores and a picture show. The Republic-Mammoth was the district's best mine, producing about $5.6 million in copper and silver between 1905 and 1928. About 1,000 people lived here in 1925. Then copper prices fell, the mines cut back, and the post office closed in November 1929.

Mining never fully stopped. Zinc carried the mines through the 1940s and 1950s until they closed in 1957, and open pits arrived in the mid-1970s. Those pits and their tailings now cover much of the townsite. In July 2025 Gunnison Copper began leaching copper at the Johnson Camp Mine on new pads built over the past year.

Timeline

From Russellville to the Johnson Camp Mine

  1. The Peabody, Republic and Mammoth claims on the east side of the Little Dragoon Mountains start a camp called Russellville.
  2. A 30-ton smelter turns out about 4 tons of copper bullion a day from ore of up to 7.4 percent copper.
  3. Russellville fades after the smelter moves to the Peabody Mine, about three miles away, and a spring blizzard. Johnson grows up half a mile from the new smelter site, as headquarters of the Peabody company and its 150 men.
  4. The Johnson post office opens, with William De H. Washington as postmaster.
  5. Johnson has 317 people and has passed Russellville.
  6. The Republic-Mammoth, the district's best mine, produces about $5.6 million in copper and silver.
  7. Arizona United Mines builds a 125-ton smelter. The Black Prince hits rich sulfide ore at 430 feet.
  8. The district's peak output year. The Cobriza company ships four cars of ore a day from the Republic and Mammoth.
  9. The town has a pool hall, a school, stores, a rooming house and a picture show.
  10. Nearly 1,000 people live in Johnson.
  11. Copper prices have fallen and the mines have cut back. The post office closes.
  12. Zinc keeps the mines going until low profits close them in 1957.
  13. Mining returns with two open pits, the Burro and the Copper Chief.
  14. Gunnison Copper starts leaching copper at the Johnson Camp Mine, with first sales expected that September.

What's left

Foundations under the tailings

An undated listing says the ruins pictured in the old ghost-town books are gone, destroyed by later mining, with nothing left but foundations. The historic maps below show how it happened. On the 1943 and 1958 sheets Johnson is a tight cluster of buildings on a road below the Johnson Mine, with the Republic, Keystone and OK mines just south and a cemetery to the northeast. By 1985 the same spot sits on the rim of an open pit with tailings beside it, and the 1996 sheet puts the pit, tailings and ponds right up against the town point.

We don't know whether the cemetery on the old maps survives, or whether it can be reached without crossing mine property.

Map & directions

Getting there

Benson is the closest city. Both routes run east on I-10 and north on Johnson Road toward the mine. The townsite is inside the working Johnson Camp Mine, so there is nothing to visit. The routed path ends on unnamed mine roads; we haven't checked where public access stops.

Road and safety notes

  • The townsite is private, active mine property. Don't enter it.
  • The Little Dragoon Mountains around the mine are full of old shafts and prospects on the USGS maps. Stay out of them.
  • The old ruins are gone. If you want to see a Cochise County mining camp, nearby Cochise, Pearce and Gleeson still have buildings.
