[NASHWAUK, MN] – Mesabi Metallics Company LLC (Mesabi Metallics) today announced its Green Financing Framework has received a Medium Green shading from S&P Global Ratings—the highest ever awarded to a global iron ore pelletizing company under the Shades of Green methodology.
Mesabi Metallics is completing construction of a state-of-the-art Direct Reduction (DR) grade pellet facility in Nashwauk, Minnesota—the first new mine and pellet plant built in the state in nearly 50 years—representing approximately $2.5 billion in private investment and targeting commercial operations in Q3 2026. The facility will supply domestic Electric Arc Furnace (EAF) steelmakers, eliminating U.S. dependence on foreign iron ore imports and anchoring a strategically critical supply chain on American soil.
S&P Global’s assessment confirms that Mesabi’s framework represents credible, significant steps toward a low-carbon future—recognizing the company as a global leader in enabling lower-emission steel production. Key factors driving the assessment include:
- Greener steel, made in America: Mesabi’s high-grade DR pellets are engineered for EAF steelmaking—the lowest-emission steelmaking route—supplying North American producers that rank among the world’s cleanest steel manufacturers.
- Energy security by design: Production systems are designed for future transition from natural gas to hydrogen, avoiding long-term emissions lock-in as clean energy technology matures.
- Best-available technology: Advanced air pollution controls, zero-discharge water management and robust tailings systems that exceed regulatory requirements.
- Responsible land stewardship: Comprehensive biodiversity protection, water stewardship and waste management programs embedded from day one.
“Earning this Green designation reflects the deliberate, capital-intensive commitment our team has made to embed decarbonization into the very foundation of how Mesabi Metallics operates,” said Peter Miller, Chief Sustainability Officer at Mesabi Metallics. “We are transforming not just what we produce, but how we operate—deploying cleaner energy, advancing water and tailings management and integrating efficient technologies that set a new standard for sustainable mining.”
The framework confirms alignment with the Green Loan Principles (2025) from LMA, LSTA and APLMA, as well as the ICMA Green Bond Principles (2025) and Green Enabling Projects Guidance (2024). S&P’s opinion is an independent assessment assigning one of six shades—from Dark Green to Red—based on environmental ambition and expected impact. Medium Green is the maximum attainable shading for the Iron & Steel sector under current global technology and energy constraints.
