Dumas Contracting has been an integral part of Hudbay’s mining team at our Lalor Mine. They have provided a full-service lateral and vertical development advance, construction and mechanical team that works closely with our people, embracing Hudbay’s core values and our “one team one vision” approach to work management. Lalor has transitioned from a base metal mine to a gold operation, and mining of the gold and copper-gold zones at current production rates would not have been possible without the full support of the Dumas team.
