Minto Mine Underground Development Project:
Capstone Mining Corporation

Commodity: Copper, gold


In 2012 Dumas commenced work at Minto, a Yukon-based copper mine owned by Capstone Mining Corporation. Originally an open-pit operation, Capstone has since engaged Dumas to develop Minto into an underground ramp-access portal mine. 
 

Dumas' current scope of work at Minto consists of development in excess of 11 metres per day, production drilling, loading, and blasting, as well as waste removal.

Our original scope of work at the site consisted of two work packages: the first was development, longhole drilling and production mucking in the 118 zone. The second package was for work in the M Zone involving drill, blast, and production mucking services. Additionally, Dumas provided mechanical, electrical and engineering services to the mine.

Despite severely cold temperatures of up to -45 degrees Celsius, our employees have persevered, achieving more than three years with no LTIs.

 

Dumas brings more than just technical expertise to our projects, and Minto is no exception. One of the mine’s challenges has been engaging the local workforce, consisting mostly of First Nations community members with minimal mining experience. To address this, Dumas worked in partnership with the Selkirk Development Corporation and launched a First Nations Mine Training Program, open to interested local candidates. This initiative demonstrates our commitment to ensuring that the communities where we work are sustainable, engaged, and given the opportunity to work with us.
