Mesabi Metallics says it will spend $15 billion on an integrated steel complex in southeast Iowa designed to produce roughly 10 million tons of steel per year, with production targeted for 2030. The company, owned by India's Essar Group, announced the project Monday at the White House alongside President Donald Trump, senior cabinet members, and Iowa Republican officials.

The announced mill will convert iron-ore pellets from Mesabi's nascent Minnesota mine into direct reduced iron using natural gas, then feed that DRI into an electric arc furnace — likely drawing on Iowa's wind-heavy grid. That DRI-to-EAF pathway would make the plant, if built as planned, one of the largest of its kind in the world and a structural departure from the blast-furnace route that U.S. Steel and Cleveland-Cliffs still operate across the Great Lakes region.

Mesabi's Iowa mill "will be one of the most efficient and environmentally friendly facilities in the world," the company said in a press release. The company did not disclose plans to substitute green hydrogen for natural gas in the reduction step, the main lever for deeper decarbonization in DRI production, citing neither timelines nor volumes for the fuel, which remains expensive and in short supply.

Alongside the $15 billion for the steel mill, Mesabi is investing nearly $3 billion to complete its iron ore mine in northern Minnesota's Iron Range — the first new iron ore mine in the United States in 50 years. "With the new steel complex in Iowa, we will complete the fully integrated American supply chain, from mine to mill," said Rewant Ruia, chair of Mesabi, speaking from the Oval Office. He said the facility "will use the latest technology, and will compete head to head with any steel plant in the world on size, quality, and on cost."

Capacity, logistics, and the 2,600-acre question

The Iowa announcement is an unveiled plan, not built capacity. Several material questions remain open, starting with ore logistics. Traditional integrated mills sit on or near the Great Lakes and receive ore by water. Mesabi's Iowa site sits on or near the Mississippi River, but the locks connecting the Mississippi and Great Lakes watersheds are generally too small for large ore carriers. Rail delivery direct from northern Minnesota appears the likely route — Ruia referenced "American ore carried on American railroads" in outlining the mine-to-mill chain, an arrangement comparable to U.S. Steel's Granite City Works near St. Louis.

Mesabi may also add DRI capacity closer to the mine. CEO Joe Broking, present at the White House event, told Itasca County commissioners on Sept. 15 that Mesabi was prepared to spend $5 billion on an expansion that would more than double the mine's annual production capacity and build a DRI plant nearby, according to KAXE/KBXE. That expansion, he said, hinges on state environmental permitting reforms and on the outcome of Mesabi's dispute with Cleveland-Cliffs over mineral leases covering 2,600 acres near the Mesabi mine — leases the state of Minnesota revoked from Mesabi after its financial troubles and later handed to Cliffs.

Elizabeth Boatman, Minnesota-based industrial decarbonization lead at consultancy 5 Lakes Energy, framed the economics: around one-third of each pellet is not iron. "Why would you want to pay for fuel and time to ship non-iron when you could just ship the iron itself?" she told Canary Media in February, pointing to the long-cleared site of a U.S. Steel integrated mill in Duluth as a possible northern Minnesota location.

Competitive context

The announcement sharpens the divide within U.S. steelmaking. Cleveland-Cliffs said last month it will use a $500 million federal loan to extend the life of the blast furnace at its Middletown, Ohio complex by 15 to 20 years — a reversal from two years ago, when it planned to use the same loan to replace that blast furnace with a direct reduction plant. Cliffs already operates the only DRI complex in the Great Lakes region, in Toledo, Ohio. In Louisiana, Hyundai recently broke ground on a nearly $6 billion steel mill that will also use the DRI-to-EAF pathway.

Hilary Lewis, steel director at Industrious Labs, called Mesabi's plan "an important, and predictable, investment in the future of iron and steelmaking in the U.S." and a signal to other "outdated, polluting" mills. "The writing is on the wall for the few coal-based furnaces left in the U.S.: Modernize, or lose out," she said by email.

Trump credited his administration's 50% tariffs on imported steel for driving the investment. Iowa Gov. Kim Reynolds said "tough negotiations took place" between the state and Mesabi, without elaborating. Commerce Secretary Howard Lutnick told reporters: "I think this deal's done. They've already worked it all out. That's why we're all together with the president."

What happens next turns on concrete milestones Mesabi has not yet disclosed: state permits and incentive agreements in Iowa, the financial close behind the $15 billion figure, the mineral lease dispute with Cliffs, and the 2030 production target the White House has now put on the record.
