"Dumas is an innovative shaft construction company, they have many years of shaft construction experience and with an excellent track record on construction safety and cost controls.“
Rick Blakey
Rick Blakey, Mine Manager - Pan American Silver
"For 25 years I have enjoyed a professional and personal relationship with Dumas. From my first position as a contractor coordinator to my current position, Dumas has been a consistent player. Solid design, pragmatic approaches to complicated problems and positive client/contractor relationships have been the mainstays of their business. It has been a pleasure growing with them."
Rob Carter
Rob Carter - Vice President, Manitoba Business Unit, Hudbay Minerals Inc.
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.

“Major Drilling has partnered with Dumas on multiple projects. The expertise within each company have created a synergy that compliments both groups to provide superior performance for our clients on Projects throughout North America.”
