The CuMo Project is an exploration of one of the largest deposits of molybdenum, copper and silver in North America located in Boise County, Idaho.


Boise County has a long history in mining. Many of the county’s communities were founded on, and derived their culture from, the mining era. Idaho CuMo Mining Corporation embraces the history of the region, yet envisions a new era for the community – an era based on modern mining practices driven by good stewardship and social responsibility-the CuMo Project Era.

ICMC is committed to understanding the complex features that comprise Boise County’s culture and environment. Industry experts will delve deep into the area’s infrastructure, social climate, environment and community needs and with this knowledge, the CuMo Project team will develop a comprehensive project plan.

The project team commits to strict adherence to Best Management Practices on public lands, exceeding expectations for community involvement and vigilant stewardship of all natural resources. On these values, ICMC will build a long and meaningful relationship with Southwest Idaho.

MO-LYB-DE-NUM--Building blocks for meaningful community engagement:

  • Community meetings, presentations and informational tours
