March 13, 2026 - An 83-year-old coal miner in Marion County, West Virginia is being recognized for a milestone few workers ever reach: 50 years underground.

Marie Jefferson, known to coworkers as “Mo,” recently marked her 50th year working underground at Marion County Coal Mine in Metz. The mine, described by those close to the celebration as an older operation, is also marking its 70th year.

A Facebook video shows Jefferson being surprised with a celebration recognizing her five decades in the coal industry. According to the post, she did not know what was happening when she came outside and said it was rare to see her emotional.

Supporters say Jefferson still works six days a week and is quick to shut down talk of retirement. They also say she was the first woman - and the first Black woman - hired at the mine, and she has never forgotten being told early on that she would be hired but would not “make it” there.

During the recognition, Jefferson was honored by the United Mine Workers of America with a shadow box containing her 20, 30, 40 and 50 year anniversary pins. She was also presented with cupcakes and a new watch, which appeared to bring her to tears in the video.

Coworkers described Jefferson as tough, determined and dedicated, saying her long career has made her a respected figure at the mine and in the community.
