In 2016, Dumas commenced work on the Borden Mine, located in Chapleau, Ontario. Operated by Goldcorp Inc. and later acquired by Newmont, Borden was designed to become Canada’s first fully electrified underground mine.
Dumas was selected to partner with Goldcorp on the Borden Lake project, providing skilled and experienced personnel to undertake the box cut and excavate a 2,680-metre exploration ramp. While some diesel equipment was initially employed, Dumas crews were also entrusted with Goldcorp’s innovative fleet of battery-powered and tethered electric equipment, supporting the company’s goal of developing Borden into a 100% electric operation. By 2017, Dumas was fully engaged in developing the new decline from surface, integrating state-of-the-art electric technology into mine development activities
