Copper mining town

Helvetia

A Swiss-named copper camp on the west slope of the Santa Ritas. A few walls, slag and a cemetery remain, and the townsite now lies inside the footprint of a planned copper mine.

Ruins · fenced · 2026 report

Most of Helvetia is private mining land inside the planned footprint of Hudbay's Copper World mine. A March 2026 article says little of the townsite remains, parts of it are fenced off for mining, and the cemetery and the Ray Mine area can still be reached. It doesn't say when the writer visited; the newest dated photos, from 2018, show the cemetery. Hudbay expects to decide on building the mine in 2026. Treat fences, gates and posted signs as closed.

Overview

Copper, a Swiss name and a mine that may come back

Helvetia sits on the western foothills of the Santa Rita Mountains, north of Madera Canyon and about 14 road miles from Sahuarita. Copper made the town. In 1875 two Tucson merchants, Pinckney Tully and Estevan Ochoa, hauled about 5,000 pounds of ore out of these hills. A Swiss-born miner, Ben Hefti, pushed to organize the district and named it Helvetia, the old Latin name for Switzerland.

The camp lived and died with the copper price. A slump closed the mines in 1883. Demand for copper wire revived them in the early 1890s, and in 1899 the Helvetia Copper Company took over. By the end of that year it employed about 350 men, and the town had saloons, a hotel, a school, a Chinese laundry, a shoemaker and a butcher. The new smelter burned down after a slag spill. A downturn in 1902 and the Panic of 1907 hit later owners, and low prices shut the mines in 1911. The post office closed at the end of 1921 and the school in 1923.

Little is left. Photos from 2014 show the smelter ruins, a fenced adobe hotel ruin, slag spilling into a side canyon, and a cemetery of wooden crosses west of town. The bigger story is what comes next. The townsite sits inside the footprint of Copper World, a copper mine that Hudbay Minerals has permitted at the state level and expects to make a construction decision on in 2026.

Timeline

Fifty years of copper booms

  1. Tucson merchants Pinckney Tully and Estevan Ochoa haul about 5,000 pounds of copper ore out of the Santa Ritas. It is the district's first recorded mining.
  2. The mining district is formally organized. Its name, Helvetia, comes from Swiss-born miner Ben Hefti's homeland.
  3. Copper prices fall and the mines shut down.
  4. The town is settled as demand for copper wire brings the mines back.
  5. The Helvetia Copper Company takes over. The payroll grows from under 55 to about 350 men in a year.
  6. The post office opens.
  7. A slag spill sets the new smelter on fire and it burns down. The company rebuilds.
  8. A downturn in 1902 sinks the company. New owners build another smelter, then the Panic of 1907 stops work again.
  9. Low copper prices close the mines.
  10. Wartime demand for copper brings a short revival.
  11. The post office closes.
  12. The school closes. Most of the last residents move to Greaterville or Tucson.
  13. Copper production in the district ends.
  14. Scenes for the Paul Newman western Hombre are filmed here. Sources give both years.
  15. Hudbay's redesigned Copper World mine plan extends over the old townsite.
  16. Copper World receives its last key state permits: aquifer protection (August 2024) and air quality (January 2025).
  17. Hudbay says it expects to decide on building the mine later in the year.

The name Copper World is older than the project. It belonged to one of the Helvetia mines, and a 1909 USGS photo caption lists it beside the Heavy Weight, Mohawk, Leader, Isle Royal, Old Dick and Omega workings above the camp. Copper production in the Helvetia-Rosemont district ended in 1961, after about 36.8 million pounds of copper. Hudbay Minerals now holds the old claims and much of the land around them.

Hudbay's first phase of Copper World would be built on its private land, more than 4,500 acres of it. A 2022 report in the Patagonia Regional Times described the redesigned plan spreading over the ridge, down through the foothills and over the historic Helvetia townsite, with South Santa Rita Road as the main access and utility corridor. The state approved the reclamation plan in October 2021, the aquifer protection permit on August 29, 2024 and the air quality permit on January 2, 2025. A state hearings office upheld the air permit on appeal, and further appeals were still pending in early 2026.

In its annual filing in March 2026, Hudbay said a feasibility study was due by mid-2026 and a decision on building the mine later in the year.

We haven't seen that decision announced. If the mine goes ahead, expect construction traffic on Santa Rita Road and less of the old townsite to survive. The cemetery lies west of the townsite on the Santa Rita Experimental Range, a research property that bordered the project on the west in the 2022 plan.

What's left

Walls, slag and a hillside cemetery

A 1996 visitor found a single adobe wall standing where the town had been, with shafts, tailings and a maze of mine roads around it. Photos taken in March 2014 show more. They include the stepped walls of the smelter, the hotel's adobe ruin inside a chain-link fence, and black slag tipped over the edge of a small canyon below the smelter. The Bulldozer Mine ruins sit northwest of town.

The Helvetia Cemetery is on Helvetia Road just inside the eastern edge of the Santa Rita Experimental Range. Its graves are marked with wooden crosses, some bound with barbed wire, and a 2018 photo shows crosses decorated with flowers.

The old USGS sheets in the next section trace the decline. The 1904 Patagonia sheet shows Helvetia crowded with building symbols and mine marks at the foot of the range, with Rosemont across the crest to the southeast. The 1958 Sahuarita sheet marks shafts, tunnels and a cemetery just inside the Experimental Range boundary west of town. By 1981 the map reads "Helvetia (Site)", with ruins and the Old Dick and Heavy Weight mines nearby.

Getting there

Sahuarita, on I-19, is the closest town. From Tucson, follow I-19 south to Sahuarita Road. Both routes end on Santa Rita Road, which climbs east toward the mountains to the townsite. We computed these routes from OpenStreetMap and haven't driven them.

Road and safety notes

  • We haven't driven this route. In 1996 the Tucson Weekly described the last stretch as dirt, with a maze of mine roads around the townsite. Expect changes since then, and turn back if the road is worse than your vehicle can handle.
  • The townsite is private mining land and is reported fenced. Respect fences, gates and posted signs, and stay out of shafts and old workings.
  • Hudbay plans to use South Santa Rita Road as the mine's main access. If construction starts, expect heavy traffic and possible restrictions.
  • Summers are hot. Carry water, and avoid the dirt roads after heavy rain.
