I guess you wiped out the Sin squad in the Sin House early in the game.

You have two choices, both of which are explained in Joining Duty, obviously you will need to reload a save prior to attempting to Go deeper into the mines and this time take notice of the newsfeed message from Petrenko as you enter the cavern.

HTH.
