Mining is our Past. Not Our Future.

Protect our air, water, and quality of life.

Stop the Idaho-Maryland Mine.

Rise Grass Valley, a junior mining company with a questionable background, wants to reopen the Idaho-Maryland Mine in Grass Valley, CA. 

why stop the mine?

Residents and businesses from all walks of life know that putting a toxic business in the middle of our beautiful community today is a really bad idea. The community's review of the Draft Environmental Impact Report (DEIR) in April of 2022 revealed significant issues and we're currently waiting to see a revised report. The supplemental Economic Impact Report just got published in November. Nevada County Supervisors could make a decision as early as 2023.
