Health sampling
ⓘA sample is a point in time compliance measurement, not an individual exposure history. These figures describe MSHA sampling records and do not establish causation or personal dose.
Metal and nonmetal contaminants (personal samples)
ⓘMany samples are screening measurements of substances with no applicable exposure limit; they are counted as samples but excluded from every over-limit figure. Over-limit shares use only limit-tested samples.

Golden Chest Mine sits in Shoshone County, Idaho, where the Census mining category is 7.2% of county employment.
Local economic context
ⓘCounty figures come from the US Census Bureau's American Community Survey, 5-year pooled estimates, so the 2023 vintage covers 2019 through 2023. The Census category is 'mining, quarrying, and oil and gas extraction', which is broader than MSHA jurisdiction and includes oil and gas workers no mine employs. These figures describe the surrounding county, not this mine, and are not a factor in any specific incident.

Quarterly safety rates
ⓘCitations per million reported employee-hours. Rates begin in 2000, when MSHA's quarterly employment data starts; earlier incidents are counted but cannot be rate-adjusted. Quarters under 100,000 reported hours are greyed: too few hours for a stable rate.

Miner was drilling and noticed his nipper had collapsed behind him. There was no apparent reason for the collapse such as getting hit by a rock or the drill leg, etc. Miner transported nipper to the surface, notified emergency personnel, and nipper was transported to Kootenai Medical Center in Coeur d'Alene, Idaho.
Employee was sitting on rear of jumbo drill as it was drilling holes at the face. He jumped off the jumbo a vertical distance of about one foot to get fuel for the jumbo and landed on the side of his right foot. The right foot became immediately painful, but he finished out his shift to 4:00 pm.
