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.

ⓘ
This rate is recorded citations divided by MSHA inspection hours, per 100 hours. It reflects inspection effort, not mine size or production.Leonardite Products Mine&Mill Operation has $92K in proposed MSHA penalties and $0 outstanding across 9 contested dockets.
ⓘ
Differences between proposed and paid penalties reflect both settlements and conference reductions and amounts still owed. Outstanding is the balance currently owed.ⓘ
Shares are computed over citations that carry the MSHA gravity and negligence coding; a small share of records are uncoded.ⓘ
Contesting a citation before the Federal Mine Safety and Health Review Commission is a lawful right. These figures state the public outcomes of that process, from MSHA's Contested Violations file.- Settled 23 · 82%
- Stood as issued 5 · 18%
ⓘ
Counts a Significant & Substantial citation as surviving when a settlement or judge's decision kept the designation, or the contest was dismissed or defaulted so the citation stands as issued. Vacated and withdrawn citations, and settlements that removed the designation, count against.ⓘ

Leonardite Products Mine&Mill Operation recorded 0.00 reportable injury cases per 100 full-time workers in 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.| Year | total case rate | days-away | fatal |

Leonardite Products Mine&Mill Operation sits in Williams County, North Dakota, where the Census mining category is 15.6% of county employment.
ⓘ
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.ⓘ
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.| Quarter | Hours worked | Citations | S&S | Per 1M hrs |

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.

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.
