why stop the mine?

6 Reasons

Rise Gold, a 16-year-old mining company that has never opened a mine and never made a profit, wants to re-reopen the Idaho-Maryland Mine here in Grass Valley. The Nevada County Board of Supervisors are expected to make a decision about the project in a few months. Here's what's at stake.

GROUNDWATER and wells at risk

Water is one of the most precious resources we have, but Rise Gold plans to pump out 1.2 million gallons every day for up to 80 years putting 300+ private wells at risk. 


Risks our health

80 years

Hardrock mining is the single largest source of toxic waste in the United States. Rise Gold wants to put a heavy industrial mining plant into the middle of our peaceful residential community. 24 hours a day. 7 days a week. For up to 80 years.

failing grade

Grass Valley gets an “F” for air quality today. The mine will make it worse with escaped dust from continuous rock crushing, loading, hauling, unloading, spreading, and compacting. With chronic lung disease deaths already at twice the state average, we can't afford any more.  


greenhouse gas

The mine calls for massive energy usage and would produce large quantities of Greenhouse Gas (GHG) Emissions completely erasing the county's plans to cut residential power consumption and curb climate change.

Toxic Spill

Their CEO's last venture polluted tribal waters, went bankrupt, and left Canadians with a mess to clean up. And many question their financials.


While Rise Gold shareholders profit, the local community gets little. The few jobs gained are offset by big quality of life impacts for local homeowners, risks for tourism and industry, and 10’s of millions lost in property values.

$10's of millions
