CALIFORNIA GOLD RUSH

The Gold Rush was far from the quaint story of rugged individualism portrayed as California's origin story. The truth is much darker. And the Sierra deserves an honest   reckoning with its history.

THE TRUTH IS...

THE DAMAGE DONE

  • Unstable tailings piles

The New Gold Rush

With gold prices breaking $5000 per ounce, foreign mining companies are coming for what is left.

Getting the last bits of gold requires industrial methods such as cyanide heap leach processes which create:

​

  • Massive scars in landscapes

  • Use vast amounts of water

  • New types of contamination

Arid Quarry Landscape

Even the state of Montana banned new cyanide mines in 1998.

While there are only 3 active cyanide heap leach mines operating in California, many others have been stopped in the past 30 years through strong local opposition. There are several outstanding proposals that are currently moving through the regulatory process, and local activists need your help to stop them.
