Grade Control FAQs
What is grade control?
Grade control is the process of drilling holes, usually in close proximity to check the quality & grade of the ore while mining is underway. This is commonly carried out after the ore body has been identified and is used to help define the mine model.
Why is grade control in mining important?
It is the most cost-effective way to define the boundaries between the ore body and the waste dirt.
What does grade control drilling entail?
Grade control drilling consists of a number of drill holes in close proximity, usually in the ore body. This allows the geologists to determine the ore grade and its changes as well as helping locate the boundaries of the mine pits where it intersects waste rock.
