MINING. The first step in our mining process is to strip overburden (which is the rock and soil overlying a resource) away from the resource. We use multiple types of equipment to do this, such as scrapers, excavators, and haul trucks, depending on the digging conditions. Next, we mine the resource with hydraulic excavators.
