Mining is our Past. Not Our Future.

Protect our air, water, and quality of life.

Stop the Idaho-Maryland Mine.

Rise Gold, a junior mining company with a questionable history, tried to reopen the Idaho-Maryland Mine in Grass Valley, CA and got rejected. But the story isn't over yet. 


In a final public hearing on February 16, 2024, the Nevada County Board of Supervisors said NO to reopening the Idaho-Maryland Mine. Thank you Nevada County! And thank you to the thousands of residents, hundreds of businesses, and dozens of groups who came together to oppose this project! Learn more.

PLEASE send an email to say thank you to the Supervisors for their courageous decision!

THE COUNTY vOTED Unanimously against the mine THREE TIMES, but it's not over yet. 

May 2023: Nevada County Planning Commissioners unanimously recommended a NO vote on both the use permit for the project and the  Environmental Impact Report (EIR). The hearing was earthshaking.

December 2023: County Supervisors unanimously rejected a separate petition submitted by Rise Gold claiming a "vested right" to mine the property without the need for a use permit.

February 2024: County Supervisors voted unanimously 5-0 to reject the use permit and deny certification of the EIR. This final decision was a tremendous victory for the community .

But it's not not over yet. Rise Gold has threatened to sue the County

why stop the mine?

The majority of Nevada County residents – from both sides of the political spectrum – oppose the Idaho-Maryland Mine. They know that putting a toxic business in the middle of a residential area is a really bad idea. 

The project includes significant and unavoidable environmental impacts that endanger this community's health and quality of life. 
A few jobs and uncertain tax revenues just aren't worth the risk.

The Project Can't Be Fixed

After almost four years of development, the Final Environmental Impact Report and project plans still didn't solve several critical problems.  Read more.


26 local and state groups called for denial of the reopening of the Idaho-Maryland Mine in Grass Valley, California. In a lengthy letter to the Nevada County Planning Commission and Board of Supervisors, the MineWatch Coalition cited environmental and economic reasons to deny the project. 

“…the reopening of the Idaho-Maryland Mine is not supported by a majority of Nevada County constituents. Nevada County is no longer a resource extraction county.  We have shifted onto a new 21st century green economy.  And our residents support this shift.  Are a few jobs and uncertain tax revenue worth the risk?”
