Stibnite Mining District
region within the U.S. state of Idaho
The Stibnite Mining District, commonly referred to simply as Stibnite, is one of the most historic mining districts in the U.S. state of Idaho. It is located in the mountains of Valley County, Idaho, approximately 10 miles (16 km) outside of Yellow Pine and 39 miles (63 km) east of McCall. The site is rich with minerals, including gold, silver, antimony (found naturally within stibnite, for which the region is named) and tungsten. Over the last hundred years, it has been home to thousands of miners, operated by several different mining companies and was critical to the U.S. war effort in the 1940s and 1950s. Mining activity stopped in the late 1990s. Since 2009, a private company has conducted exploration in the area in consideration of new mining activity.
An area of 2,828 acres (1,144 ha) within the Payette National Forest was added to the National Register of Historic Places on July 19, 1987, as the Stibnite Historic District.
History
Miners first came to Stibnite during Idaho’s gold rush days in 1899. Over the next few years, the number of miners at the site continued to grow and several operators, including United Mercury Mining Company and Bradley Mining Company, started working in the area.
In 1938, miners started focusing their efforts on the Yellow Pine Pit.

Why this record matters
The phrase “region within the U.S. state of Idaho” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 5, 2026. The linked authority identifier is Q28402996. Authority coordinates are 44.898, -115.339. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2009, 1987, 1899 and 1938.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
