ArcelorMittal identifies potential to increase production of iron-ore concentrate at ArcelorMittal Mines Canada to 30 million tonnes per annum

Regulatory News:

ArcelorMittal today announces that a scoping study has identified the potential to utilize ArcelorMittal Mines Canada’s existing infrastructure system and to increase annual production of iron-ore concentrate to 30 million tonnes per annum. Several development options are currently being considered and further expansions beyond that currently under implementation are being investigated.

In May 2011, the company announced that it had launched an investment program to increase annual production at ArcelorMittal Mines Canada from 14 to 24 million tonnes per annum by 2013. This investment program is currently under implementation.

Pre-Feasibility and Feasibility studies will now be commissioned for the production increase to 30 million tonnes per annum.

Peter Kukielski, Member of the Group Management Board responsible for ArcelorMittal’s global mining business, said: “We have always known that ArcelorMittal Mines Canada is a flagship asset with considerable opportunity for expansion. This latest study marks the next step in realizing that potential.”
