Kennecott Utah Copper — History
source confidence: Medium status: Useful updated 2026-08-11
Summary
The official history page for Kennecott Utah Copper covers the development of the Bingham Canyon Mine from early twentieth-century origins through current operations. It describes the mine's scale, production history, and the company's role as a subsidiary of Rio Tinto.
Useful Claims
- Kennecott has been mining and processing minerals from the Bingham Canyon Mine since 1903.
- The first phase of the South Wall Pushback extended the mine's life to 2026; stripping for the $1.5 billion second phase, extending operations to 2032, remains on track.
- Feasibility studies are progressing to extend open-pit mining beyond 2032; if approved, the planned Apex expansion could produce around 1.5 million additional tonnes of copper and extend the mine's life to approximately 2040.
- This capture does not state that Bingham Canyon is the largest open-pit copper mine by volume excavated, that it has produced more copper than any other mine in history, or that it holds National Historic Landmark designation.

Reliability Notes
This corporate page is self-interested in its positive framing of the environmental and labor record, but useful for production statistics and chronology. Production and engineering claims are independently corroborated by USGS and mining-history sources. The captured document is Rio Tinto's current Kennecott operations page, not a dedicated history page, and it does not state several of the broader chronology and superlative claims associated with Kennecott.
The legacy Kennecott URL redirects to the subsidiary's current operations page on riotinto.com, its parent company's domain.
