ICL: Leaks and spills from mining could harm public lands, water quality, and fish

BOISE — On Friday, August 14, the U.S. Forest Service released a draft environmental report on the Stibnite Gold open pit mining project near McCall and the Frank Church-River of No Return Wilderness. ICL’s preliminary analysis of the agency’s Draft Environmental Impact Statement (DEIS) reveals project construction and toxic waste threatening pristine land and water, and the area’s endangered fish. 

Take action against Midas Gold and the Stibnite gold project!

Your voice matters! Now is the time for the public to weigh in and say NO to Stibnite.

This is the same DEIS that contains portions written by Canadian company Midas Gold, owner of the Stibnite project. The Forest Service allowed Midas to conduct its own biological assessment as part of the DEIS. The Forest Service also has announced a 60-day public comment period that is scheduled to end on Oct. 13, and numerous requests have been made to extend this time to 120 days. 

John Robison, ICL’s public lands director, said, “The public needs additional time to review the Forest Service’s environmental report that took over three years to write, but we’ve only been given two months so far. We represent Idahoans from all across the state who feel that this project is an existential threat to the South Fork Salmon River, surrounding lands, and area fish and wildlife.” 

He added that ICL will be conducting a more comprehensive review of the DEIS in the coming weeks. 

This is the last opportunity for the public to comment on the Midas Gold’s open pit mining project in the headwaters of the South Fork of the Salmon, which contains critical habitat for Chinook salmon, steelhead and bull trout. 

The DEIS analyzes four different options for the development of this open-pit mine, including  Midas Gold’s proposal, which would generate millions of tons of toxic mining waste and disturb a total of nearly 3,500 acres

Much of the impacts in the Midas Gold “preferred alternative” are in pristine, undisturbed areas despite the mining company stating this is a restoration project. Under this option, large amounts of toxic material from previous mining operations would be combined with millions of tons of new toxic mine waste and dumped in a pristine, undisturbed valley. The project is so complex that the DEIS is over 2,600 pages long, plus an additional 15 appendices of supporting information, bringing the total to nearly 6,000 pages. 

The Midas “preferred alternative” includes:

  • Three open pits, totaling 510 acres, from which gold would be mined.
  • A tailings storage facility that would consume over 400 acres and fill upper Meadow Creek, a pristine stream, with up to 100 million tons of mining waste. 
  • A 20% direct loss of Chinook salmon critical habitat in the analysis area.
  • Over 160,000 square meters (~40 acres) of potentially acid-generating rock exposed in mining pit walls – enough to cover 27 football fields.
  • A new mining road that would be built through an inventoried roadless area, with a portion on the border of the Frank Church-River of No Return Wilderness. 
  • Mining activities that would contaminate groundwater and require construction of a water treatment facility. 


ICL works to ensure that mining activities don’t threaten human health, special places or Idaho’s clean water. ICL scrutinizes proposed new mines, improves those with manageable risks and fights those that are not in Idaho’s best interests.
