Rio Tinto’s Q1 Production Drops Amid Pause to Honor Lost Colleagues
The mining company’s Diavik Diamond Mine lost four employees in a plane crash in January.

London—Rio Tinto reported a 22 percent year-over-year drop in production in the first quarter at its sole remaining diamond operation, the Diavik Diamond Mine.
The mine produced 740,000 carats in Q1, compared with 954,000 in the first quarter of 2023.
Rio Tinto reported first-quarter results for Diavik last week alongside results for its iron ore, bauxite, aluminum, and copper operations.
The first thing the company mentioned in its news release was the January airplane crash that killed six and injured one.
“We have been deeply affected by the loss of four Diavik colleagues and two airline crew members in a plane crash in January,” Rio Tinto Chief Executive Jakob Stausholm said. “This tragedy has strengthened our resolve to never be complacent about safety.”
The plane, a chartered Jetstream twin-turboprop en route to the remote Diavik mine, crashed shortly after takeoff from Fort Smith Airport in the Northwest Territories on the morning of Jan. 23.
The four Diavik workers killed in the crash have been identified as Diane Balsillie, Howard (Howie) Benwell, Joel Tetso, and Shawn Krawec, while the sole survivor was Kurt Macdonald.
Paszolo Alba was the airline crew member who was killed, while the second crew member hasn’t been publicly identified.
Rio Tinto said last week that it is continuing to work with Canadian authorities to determine the exact cause of the crash.
To grieve and honor the workers who died, the mine took a “production pause,” which led to the 22 percent year-over-year drop in production.
Quarter-to-quarter, production rose 12 percent from 659,000 carats mined in the fourth quarter of 2023.
Rio Tinto said continued production improvement from the A154 North underground pipe and ore development at the A21 underground project helped to offset the depletion of two ore bodies last year.
The company announced in March that it is going underground on the A21 pipe, a multi-million-dollar project that, if fully approved, will extend Diavik’s life into the first quarter of 2026.
