Employment and Training

Dumas is proud of our record for cultivating and sustaining productive and positive relationships with our partners. Collectively, Dumas has facilitated 10 training schools in partnership with Indigenous communities across Canada. Below are two of our training partnership agreements that represent and highlight some of the best practices we have developed. These initiatives provide us with benchmarks to ensure that we succeed and stand with our partners to continuously improve the outcomes for all stakeholders.

Matachewan Aboriginal Access to Mining Jobs Training Strategy (MAATS)

MAATS, in partnership with Dumas, Northgate Minerals Corp. (now Alamos Gold Inc.), and Human Resources and Skills Canada, provided innovative employment and training opportunities for Indigenous peoples in rural and remote areas. Dumas was involved in this program for 1.5 years and provided technical training during this period. The program’s success led to the creation of its sister program, NTPF, in which Dumas trained 46 participants over a 3.5 year period. MAATS continued to provide counseling and support services to these participants.

Northern Training Partnership Fund (NTPF)

The NTPF offered in partnership with Dumas in Ontario was one of the most successful in Canada, with 46 participants, 90% of whom found employment within a few weeks of graduating. Training was provided in the following areas:

Underground Miner Training
Apprenticeships / Heavy Equipment Operator Training
On-The-Job Training
Upgrading / GED
Business Diplomas
Driver Education
Pre-Employment / Life Skills
First Aid / WHMIS

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.
