Mesabi Metallics outlined a plan at the White House to build a $15 billion steel plant in Iowa that would use iron ore from Minnesota and target a 2030 production start, according to reporting cited in the source text. The Post Millennial reported that President Donald Trump unveiled the plan alongside Mesabi Metallics CEO Joe Broking in the Oval Office. A White House official cited by CNBC said production would begin in 2030, per the source text.
What Mesabi and the White House outlined
Mesabi Metallics is quoted as saying the project would develop “100% American steel: mined, melted and poured in Minnesota and Iowa.” The Post Millennial characterized the proposed facility as the largest in U.S. history; that superlative has not been independently verified here.

The source text cites figures for the proposed build-out: phase-one output of 7.5 million tons of steel annually, scaling to 10 million tons at full capacity; about 6,000 construction jobs; nearly 2,000 permanent manufacturing and mining positions; and a $95 billion contribution to the U.S. economy. The source does not provide underlying documentation for these estimates.
During the announcement, Trump is quoted as saying, “This steel will be mined, melted, and made right here in the USA, which is something very unusual,” and, “Everyone is building their plants here because they don’t want to pay tariffs. It’s really not that complicated,” according to the source text.
Iowa vs. Minnesota: quotes on siting
The source text frames the siting choice as a loss for Minnesota. Republican state Rep. Spencer Igo, who represents the Iron Range, is quoted as calling the news a “gut punch” and saying, “We cannot keep watching billions of dollars in investment and thousands of good-paying jobs go elsewhere and pretend there is nothing we can do about it.”
Mesabi Metallics CEO Joe Broking “told county officials the company needs ‘more efficient state permitting and more competitive incentives’ before investing further in Minnesota,” per the source text.
Supply chain: Minnesota ore
The source text states the Iowa plant would be supplied by a Mesabi Metallics iron ore mine in Nashwauk, Minnesota, described as the first new Iron Range iron ore mine in roughly half a century. It says the mine “opened just weeks ago,” has “more than 200 workers,” and plans to employ “350,” and adds that two taconite facilities on the Iron Range closed last year. These claims have not been independently verified here.
Tariffs and causation claims
The source text links the proposed investment to steel tariffs and asserts that “Trump’s 50 percent steel tariffs – imposed last year – have sparked the single largest domestic steel investment in American history.” That causal claim and the tariff specifics require independent confirmation. Trump’s quotes above reflect his framing at the White House event, according to the source text.
What’s unconfirmed
Key details not provided in the source text include the exact Iowa site, permitting status, financing structure, environmental reviews, and third-party confirmation of the output, jobs, and economic-impact figures. The “largest-ever” characterization, the Nashwauk mine timeline and workforce counts, and the tariff rate and timing also require verification.
