About Protect Thacker Pass

Why are we protesting?

Because we envision

  • A world in which we prioritize the health of future generations. 
  • A world in which we live in harmony with the natural world, rather than relying on extraction. 
  • A world in which blowing up a mountain for lithium is just as unacceptable as blowing up a mountain for coal. 

Nevada is the driest state in the USA, yet the mine plans to use 2,600 acre-feet (850 million gallons of water) per year in phase one, and 5,200 acre-feet (1.7 billion gallons or water) per year in phase 2.

What do we want?

  • We want people to understand that lithium mining is as dirty as coal mining.
  • We want to stop Lithium Americas from physically disturbing Thacker Pass.
  • We want the world to know what is happening here.


About Thacker Pass

Thacker Pass is a physical feature in Humboldt County Nevada, part of the McDermott Caldera approximately 60 miles northwest of Winnemucca. It was formed 16 mil + years ago, is traditional and unceded territory of the Paiute and Shoshone people, and is United States Bureau of Land Management (BLM) public land. The traditional Paiute name of Thacker Pass is Pee-hee-mm-huh meaning “rotten moon.” Now it is also the proposed site for a massive lithium mine that would destroy the area and valuable habitat for the creatures who live there.

It is a stunningly biodiverse, wild, expansive, and beautiful desert in the mountains.

The lithium mine is “to supply the electric car industry”.

Thacker Pass is habitat for:

  • Crosby’s buckwheat (rare desert wildflower only found in this area)
  • King River pyrg (a critically endangered snail)
  • Rabbitbrush
  • Jackrabbits
  • Big horn sheep
  • Coyotes
  • Golden Eagles
  • Sage grouse
  • Pronghorn antelope
  • Old Growth Sagebrush 

Location of proposed mine: North-central Nevada

About Lithium Mining

“The future demand for lithium is truly staggering…. Battery demand is rising at the rate of one to two new lithium mines per year, growing to two to three mines per year by 2020.” — Mike Kobler, CEO, American Lithium, exploring lithium mining in Southern Nevada

Lithium Americas is a Vancouver, Canadian-based company. They want to mine 5,000 acres using an open pit which would be roughly one mile across and two miles wide. The mine would burn around 11,300 gallons of diesel fuel per day. It would provide up to 25% of global lithium supply.

  • Lithium is present at 2000-9000 ppm (0.2-0.9%)
  • Producing one ton of lithium will require strip mining and processing between ~110 and 500 tons of Earth.
  • The end product is lithium carbonate or lithium hydroxide.
  • They will build a sulfuric acid plant at site to convert molten sulfur into sulfuric acid to leach the lithium from clay stone. Following the leaching, the lithium bearing solution is purified using crystallizers and reagents to produce battery grade Li2CO3.
  • Hundreds of Tons of Sulfur (waste from Oil Refineries) will be trucked in and burned every day at the mine site (roughly 75 semi loads of sulfur a day).
  • This in turn will produce thousands of tons of Sulfuric acid every day, up to 5800 tons a day.
