The developers of a copper-nickel mining project in northeastern Minnesota have announced plans to conduct studies aimed at enhancing environmental safeguards and improving the mine's efficiency. The $1 billion open-pit mine near Babbitt and processing plant near Hoyt Lakes, a joint venture between Glencore and Teck Resources, is set to undergo potential design changes to align with clean energy goals.
The project, formerly known as PolyMet and now renamed NewRange Copper Nickel, has faced delays due to legal and regulatory challenges. The company is moving forward with site preparations while exploring ways to reduce greenhouse gas emissions and enhance sustainability.
Environmental groups have raised concerns about the project's environmental impact, particularly the risk of acid mine drainage from sulfide-bearing ore. The developers are now considering alternative options for waste storage, water treatment, production acceleration, and carbon emission reduction.
The studies will evaluate the feasibility of different waste storage designs, transportation methods, and production levels. Any significant changes will undergo additional environmental reviews and permitting processes, with opportunities for public input.
The current plan involves storing mine waste in a former iron mine tailings basin and using diesel-powered trains for ore transportation. The developers are exploring potential improvements in waste storage, transportation efficiency, and wastewater treatment to meet or exceed state standards.
The project, initially thought to have all necessary permits, faced setbacks from court rulings and permit revocations. The developers are now working to address concerns raised by regulatory agencies and environmental advocates to ensure compliance with environmental regulations.
Despite the challenges, the developers remain committed to transparency and stakeholder engagement throughout the project's development. The upcoming studies aim to enhance environmental protection measures and operational efficiency while addressing environmental concerns raised by critics.
