Underground Mining and Impacts to our Environment

September 29, 6pm

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. Nevada County Supervisors could make a decision as early as 2023.

"Earth provides enough to satisfy every man's needs, but not every man's greed."

-Mahatma Ghandi
