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.

Lucky Strike Mine & Mill recorded 6.99 reportable injury cases per 100 full-time workers in 2024.
Injury rate, 2024
ⓘThis rate is reportable injury cases per 100 full-time-equivalent workers per year, computed as 200,000 times cases divided by MSHA operator-reported employee-hours. Cases are injuries MSHA graded degree 01 through 07; accident-only events that hurt no one are excluded, and so are contractor injuries, whose hours do not attach to a single mine. Rates begin in 2000, when quarterly employment reporting starts, and are withheld below 20,000 hours in a year.

fatality rate
Above average. The US metal and nonmetal mining average was 1.77 and the all-US-mining average was 2.08 cases per 100 workers.
In Colorado, metal and nonmetal mining averaged 1.78 cases per 100 workers that year.
Under 100,000 employee-hours were reported that year, so a single case moves the rate by two or more. Read the figure as approximate.

Lucky Strike Mine & Mill sits in Gunnison County, Colorado, where the Census mining category is 0.3% 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.

September 24, 2024CO · Metal/Non-Metalwarehouseman, bagger, palletizer/stacker, store keeper, packager, fabricator, cleaning plant operatorHANDLING OF MATERIALS
The employee was helping lift replacement blow bars for the crusher repair. EE went to lift the blow bar and felt a funny pinch in their back. After resting for a minute, EE decided it best to go to the hospital for evaluation. The doctor released EE without treatment and told EE not to return to work for three days. All conditions were normal at the time.
January 31, 2024CO · Metal/Non-Metalwarehouseman, bagger, palletizer/stacker, store keeper, packager, fabricator, cleaning plant operatorOTHER
The employee passed out on the job due to a personal medical reason. The employee was found by another employee. EE was woken up and seemed confused and shaky. 911 was called out of precaution and the employee was taken down to meet the ambulance. The employee was released to return to duty on the next set of shifts.
The employee slipped while walking down a set of stairs and landed on EE's back. EE felt good and that it was not necessary to go see a doctor. EE continued to work until 12/24/2022 and then felt bad enough that EE went to the doctor. The doctor told EE to take 10 days off and then return to light duty.
May 23, 2022CO · Metal/Non-Metalhaul/off road/coal/ore/pit/quarry/rock/rubber tire truck driver, transportation truck driverSLIP OR FALL OF PERSON
It was a normal shift and weather conditions. The truck driver went to unstick the dump truck cover tarp and tripped and fell to the ground. EE braced the fall with hand and hurt wrist. We took EE to Urgent Care for X-ray and the results show that EE has two small bones in the hand that were fractured.
