Dumas has a long-standing relationship with Glencore at the Kidd Mine. From 2002 to 2011, Dumas has excavated an average of 5,000 metres per year from multiple lateral development headings. At 9,600 feet below surface, Dumas worked to drive one of the deepest ramps in the world. Until 2011, Dumas completed 1,000 metres per year of raise work.
The Dumas construction crews have completed many refuge stations, bin rehabilitation projects, manways and miscellaneous construction work at the lower levels of the mine.
