Mariana Minerals Co.
Mariana Minerals Co. made 17 filings covering 17 positions in this release. Across them it committed to pay at least a median of $150,000 a year. 17 of those 17 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
Mariana Minerals Co. has filed no permanent labour certifications in this release. That is the first step of an employment-based green card, so on this data there is no sign it sponsors one — though a release covers a fiscal year, and an employer that sponsored earlier would not appear here.

A wage is shown against the prevailing wage for the library year the filing itself cites, not the year current today — measured against the wrong year, a correctly-filed wage reads as underpaid.
