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.

Leonardite Products Mine&Mill Operation recorded 0.00 reportable injury cases per 100 full-time workers in 2025.

Injury rate, 2025
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
No reportable injury cases in any year shown. Employee-hours were reported in each of those years, so these are true zeros rather than missing data. Citations, listed in the compliance record above, are inspector-found violations and are counted separately from worker injuries.
Below average. The US metal and nonmetal mining average was 1.65 and the all-US-mining average was 1.97 cases per 100 workers.
In North Dakota, metal and nonmetal mining averaged 0.62 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.

Leonardite Products Mine&Mill Operation sits in Williams County, North Dakota, where the Census mining category is 15.6% 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.

Leonardite Products, LLC · Accident type, without injuries

Maintenance began 4/24/2026. Grinding on 4/30/2026, with fire watch in place, caused smoldering in combustible material near the work area, which was extinguished. Additional grinding occurred 5/1/2026. On 5/2/2026, a fire was reported on the plant roof at 6:05 AM and extinguished within one hour. Sections of the metal roof were cut to access hot spots, requiring replacement.

June 23, 2009 ND · Metal/Non-Metal IGNITION OR EXPLOSION OF GAS OR DUST
Leonardite Products, LLC · Accident type, without injuries

The electrical service in that area was shut off. 1 pallet had deep burns. It appears spontaneous combustion occurred in a bulk bag filled with 1/4 inch leonardite and soda ash. The moisture of the leonardite was approx 28%, higher than we recommend. We believe the combination of moisture, leonardite and soda ash caused an exothermic reaction. A chemist said this is possible.

2007 · 1 incident

December 6, 2007 ND · Metal/Non-Metal FIRE
GeoResources Inc · Accident type, without injuries

Cause is unknown at this time. There is only one shift per day from 8am - 4pm so no one was there at the time of the fire. Grinding equipment was damaged and a wood building was destroyed. Also, there was some damage to an adjoining steel storage building. There were no injuries.
