The History of Stibnite

History

The Stibnite Gold Project site is located in one of the most historic mining districts in all of Idaho. It has been home to thousands of miners, operated by several different companies and was critical to the U.S. war effort in the 1940s and 1950s. After many decades of mining, Stibnite is still rich with minerals but also in much need of environmental repair.

1899 Mining first began in the Stibnite area in 1899 during the Thunder Mountain Gold Rush.

Miners flocked to the region to work for the multiple companies operating in the Stibnite-Yellow Pine mining district.
1938
1938 Mining in the Yellow Pine pit began in 1938, which has blocked fish passage to the upper stretches of the river ever since.

The town of Stibnite grew significantly when the US Government declared antimony as a critical mineral for the WWII effort.

After the war years, many of the original structures were dismantled and people moved out of Stibnite.

From 1959 to 1965 an estimated 30,000 tons of sediment erode into the Salmon River.

Active mining restarted in the 1970s and continued sporadically until the 1990s.
1997
1997 All mining activity stopped by 1997; the U.S. Government conducted limited cleanup of the site, but the reclamation is still incomplete.
2009
2009 Midas Gold was the first company to study the Stibnite Gold Project area as a comprehensive geological region.
2010
2010 Midas Gold's early efforts at the Stibnite Gold Project site included repairing previous environmental damage while exploring for new mineral resources.

Our Plan for the Future

We can restore the site. 

We have a plan for the future of the Stibnite Gold Project.  Our plan is different because we started with the idea that mining and the environment can work hand in hand. We can take the large mineral deposits of gold and antimony that remain in an area extensively mined for 100 years and use them to fund the environmental restoration this historic mining district desperately needs.

For the past decade, we studied the economic and environmental opportunities at Stibnite and gathered ideas from the community. In 2016, we gave our plan to the U.S. Forest Service and entered into the formal permitting process. Since that time, we have been providing additional information to the regulators and answering all of their questions, and yours, about the proposed Stibnite Gold Project.  You can read more about it here.

Geology

The geology of Idaho is unique and it has taken millions of years to create our state’s multiple mineral-rich regions.

Idaho’s unique and mineral-rich geology has been created by huge tectonic forces operating over millions of years.

The Stibnite Gold Project area sits on top of nearly 14,000 square miles of mountainous granite known as the Idaho Batholith, which formed about 100 million years ago. Later, about 50 million years ago, volcanic activity cracked the granite and left behind the mineral deposits that human scientists have found in modern times.

We continue to explore this part of Idaho and our scientists are working collaboratively with the Idaho Geological Survey, the United States Geologic Survey and academic institutions such as Boise State University, the University of Idaho and the University of Nevada to improve our understanding of the wonderful and unique geologic history of the Stibnite Gold Project site.
