The secondary drilling project at Arcelormittal’s Mont-Wright mine is defined by all the drilling activities in support to the operations of the mine’s production drills. Without being limited to it, the project includes pre-cut drilling, redrills and corrections of blasting anomalies in the mine, developments and rocks. The project is characterized by the necessary use of long casings. We have on this project all the auxiliary equipment, such as tank, dumpsters, water trucks, boom trucks which have allowed us to be 100% autonomous in our operations for more than 25 years now.
