The White House says Mesabi Metallics plans to invest about $15 billion to build a new steel plant in eastern Iowa, a project the administration called the largest steel facility in U.S. history.
President Trump on Monday described the Mesabi Metallics project as a major manufacturing investment in Iowa and the White House said the plant would be built by the Minnesota-based company, using ore from the company’s operations in Minnesota.

The White House and multiple local outlets said the investment is roughly $15 billion and would create between about 1,700 and more than 2,000 jobs; officials and announcements gave a 2030 target as the earliest start of steel production.
Mesabi Metallics recently opened an iron-ore mine in Nashwauk, Minnesota, and several reports tied the planned Iowa mill to ore from that operation rather than imported feedstock.

Analysts and business commentators immediately noted that the public announcements included limited detail on financing, a final site selection and binding construction contracts, raising questions about the project’s execution timeline.
Officials framed the plan as part of a push to increase domestic steel capacity; the White House statement said the mill would be “mined, melted, and made right here in the U.S.A.,” according to an administration social post accompanying the announcement.

With details still emerging — including final permits, funding commitments and a confirmed site — observers said the announcement is a major policy and industrial development to monitor rather than a finished transaction.
