The Mt. Vernon Mine is not MSHA regulated at this time, and shows up in the database as "abandoned". So, no worries about MSHA. Jared is gaslighting you about that. Or maybe he doesn't understand how things work.
So who actually owns the Mt. Vernon Mine? They are federal mining claims, so the federal govt. owns the land. If the claims are valid (and presumably they are), who is the actual claim holder? Lazarus Mining?
