Dumas Contracting

Dumas Contracting Ltd. (“Dumas”) is a leading, full-service underground mining contractor, providing services to clients throughout the Americas. Dumas is headquartered in Toronto, Ontario, Canada, with numerous active projects and offices across Canada, Mexico, and Guatemala.  Over the years, Dumas has completed over 500 projects for over 40 clients across 10 countries, and employed over 8,000 people.

Dumas provides concept to completion underground mining services that are fully integrated with other activities being performed by mine owners and other contractors on project sites.  Project services include mine development, production, infrastructure, and general construction projections. Dumas has the capability to perform virtually any service underground from large-scale vertical shaft sinking projects to a complete production mining operation. Large-scale shaft-sinking projects are one of the most complex types of underground projects, with challenges that include poor ground conditions, inclement weather, and extreme depths.

“Safety is our number one priority at Dumas. We’re absolutely committed to our Zero Harm policy that every employee goes home healthy and safe every day. It’s more than just a policy, it is a culture of safety here that we embrace daily at work and in our homes,” says Wayne Mohns, Dumas’ Vice President of Canadian operations.  Dumas is the winner of four Safety Innovation Awards from the Ontario Mine Contractors Safety Association over the past seven years. Additionally, Dumas is a leader in emergency preparedness, with an in-house mine rescue team.

The company’s diversified team of engineers and technical service professionals also offers a wide range of practical and design solutions across all aspects of underground mining. They include: conceptual and scoping studies, pre-feasibility and feasibility studies, mine design and planning, mining methods, mine access planning, mine development planning, material handling systems, shafts and hoisting systems, mine facilities and infrastructure, general arrangement and conceptual design drawings, detailed design drawings, ventilation assessments, tender documents, procurement support, and project and construction management.

Mohns believes that in a competitive industry, Dumas’ strength is the fact that the company remains flexible and local. “We’ve grown over the years, but we still remain client-focused with a grassroots mentality. We attract a workforce that knows the Dumas name. We work with our clients to best fit with their objectives with good people and a strong and modern equipment fleet.”
