MP Mine Operations LLC
MP Mine Operations LLC made 10 filings covering 10 positions in this release. Across them it committed to pay at least a median of $125,000 a year. 8 of those 10 state a minimum and no maximum, which is what an employer is required to file — it is the floor it is bound to, not a salary offered.
Green-card sponsorship
MP Mine Operations LLC filed 1 permanent labour certification between 2026-04-23 and 2026-04-23, of which 1 was certified. That is the step an employment-based green card starts with, so this employer does sponsor them.
