MEXICO CITY, July 19 (Reuters) - ArcelorMittal's Mexican

unit has lost an estimated 1 million metric tons in steel output

due to a strike at its Lazaro Cardenas facilities, the company

said in a statement.

ArcelorMittal said on Thursday that the 55-day blockade

ended after workers approved a new settlement that includes an

8% pay hike for employees and review of their collective

bargaining agreement, but warned on Friday morning that some

workers had continued to block the facilities.
