Jenny Campbell, Survey Technician
I work with two other surveyors in a team led by a surveyor party leader who plans what we do. The mine planners and geologists request what type of mark up is needed and by when. Daily tasks include marking-up centerlines for drifts, grades marks, diamond drill holes and other things for drillers.
The diamond drillers drill holes 100 feet long or more. The core is sent to the surface core shack where geologists log it to see where the ore and other types of rocks are. They interpret that information into a model so we have a visual representation of a particular area underground. The mine planners then create a plan to reach and extract the ore.
*Note: A draft is an engineering drawing or blueprint. Grades refer to the slope of the area.
