The Pioneer Mine was an underground iron mine in Ely, Minnesota, United States, in operation from 1889 to 1967.

[2] The Pioneer Mine Buildings and "A" Headframe were listed on the National Register of Historic Places as a historic district in 1978 for their state-level significance in the themes of engineering and industry.

[3] They were nominated for being some of the last vestiges of a once-common mining technique on the Vermilion Range.
