Project Facts

PROJECT DESCRIPTION
The TMM Project is based on an underground mine plan focused on the development of the Maturi mineral deposit, located approximately nine miles southeast of the city of Ely, Minnesota, and 11 miles northeast of the city of Babbitt, Minnesota. The production of ore will generate marketable copper and nickel concentrates.

STRATEGIC METALS
Copper, nickel, platinum, palladium, gold and silver – metals of strategic importance to the U.S. economy and national defense.

PROJECT HIGHLIGHTS
Location: The TMM Project is based on an underground mine plan focused on the development of the Maturi mineral deposit, located approximately nine miles southeast of the city of Ely, Minnesota, and 11 miles northeast of the city of Babbitt, Minnesota.

Jobs: The TMM Project will create approximately hundreds of direct full-time jobs when the mine is in operation. According to a University of Minnesota Duluth study, the Project would generate approximately two more indirect jobs per direct job at the mine site in the region’s economy.

Facility Locations: The facility locations will be based on sound environmental and economic principles, such as minimizing surface impacts, minimizing waste impacts, citing facilities near existing industrial areas and minimizing overall environmental impacts.

Underground Mine Site: When in production, all waste rock generated from underground mining activity will be used as underground backfill. Similarly, about half of the tailings produced by the concentrator in the processing of mineralized ore will be returned to the underground mine as backfill.

Concentrator Site: The concentrator is the main facility for processing the mineralized ore mined from the underground mine and capturing the valuable metals.

Tailings Storage Facility (TSF): The TSF will be used to store tailings not returned to the underground mine.

ENVIRONMENTAL ASSESSMENTS
Twin Metals has been conducting environmental studies and assessments for more than five years – and these efforts will continue during development of the MPO. Environmental information from in and around Twin Metals Minnesota’s land and mineral assets will feed into the formal, Draft Environmental Impact Study (DEIS) that will be conducted by state and federal agencies. Key environmental issues include: surface water quality and hydrology, threatened and endangered species, air quality, plant life, wetlands and socioeconomic factors.

ENVIRONMENTAL AND OPERATING PERMITS
Numerous state environmental permits will be required to plan, construct and operate the proposed underground mine. Multiple federal and state regulatory agencies and Native American tribes and bands will be part of the permitting process.

EMPLOYEES
Twin Metals Minnesota has 16 Minnesota-based employees across two offices. Through its project development activities, Twin Metals has supported as many as 200 consulting/contractor jobs.

JOBS FOR GENERATIONS
The Twin Metals Minnesota project will create hundreds – potentially thousands – of long-term mining jobs. According to a University of Minnesota Duluth study, the Project would generate approximately two more additional indirect jobs per direct job at the mine site in the region’s economy.

MINING WAGES
Average mining wages and benefits significantly outpace other industries in Minnesota.

According to the U.S. Bureau of Labor Statistics, the average annual wage for a Minnesota mining job in 2015 was $78,635, nearly $25,000 above the all-industries average. Mining offers living wages that can support a family, sustain communities and drive economic growth.

CAPITAL INVESTMENT
More than $400 million has been invested in exploration and project development to date.

TAX REVENUE AND ROYALTIES
The TMM Project will generate significant tax and royalty revenue for state and local governments as well as local school districts.
