Millwrights Constructing Minnesota’s First New Taconite Mine in Nearly 50 Years

Mesabi Metallics is forging ahead with the construction of a new taconite mine and pellet production facility in Nashwauk, MN, on the historic site of the former Butler Taconite. Once completed, this project will mark the first new taconite operation to open in the state in nearly half a century, revitalizing Minnesota’s Iron Range and reaffirming the region’s place at the heart of America’s steelmaking industry.
As one of the largest industrial projects ever done in the state, everything about the Mesabi Metallics development is big. For months, members have been hard at work enclosing buildings, erecting conveyors, and installing state-of-the-art mining equipment. A total of 3,289,000 work hours were completed in just under two years (December 2023-September 2025).
Among those essential to the build are more than 40 skilled union millwrights, whose precision, expertise, and craftsmanship are critical to installing the massive mechanical systems and heavy industrial machinery that will complete the new facility. Millwright members are responsible for assembling and aligning the conveyors, crushers and processing equipment that form the backbone of the taconite processing. Their work ensures the plant will operate efficiently, safely, and reliably while laying the groundwork for decades of productivity once the facility is online.

“The craftsmanship and precision the millwrights bring to this project are second to none,” said Joe Broking, President & CEO of Mesabi Metallics. “Their expertise is what turns engineering blueprints into operating assets capable of generating returns for all stakeholders. This collaboration between Mesabi Metallics and the skilled trades is building the future of Minnesota’s Iron Range as well as the future of the American steel industry.”
The project’s impact extends far beyond the mine site. It represents a major economic engine for northeastern Minnesota, creating hundreds of union construction jobs, more than 350 permanent positions once building is complete, and many indirect jobs across the region that will support local business and expand regional economics.
The new mine and processing plant will be powered by cutting-edge, environmentally responsible technologies. Electrically powered shovels and drills, advanced air pollution control systems, recycled water, and optimal environmental practices will ensure that operations minimize emissions and environmental impact.
Once operational, the facility will produce seven million metric tons of Direct Reduction (DR)-grade iron ore pellets each year. These high-quality pellets will supply U.S. steel producers with a reliable domestic source of material essential to decarbonizing steel production.

The Mesabi Metallics project is now more than 70 percent complete. With most of the major equipment already on site and installation well underway, the project continues to move steadily toward its June 2026 completion goal. Approximately 500 skilled union workers are on site daily, ensuring that progress remains on schedule. Through the skill and dedication of our workforce, Mesabi Metallics is building a legacy of innovation, sustainability, and opportunity for Minnesota’s Iron Range.
