Drilling Program – Grade Control
Reverse Circulation is the most commonly used drilling method for grade control in open pit mining operations. Grade control is used to define the ore grades and ore blocks in the pit and also provide knowledge for mine planning and blasting.
This information is critical to reduce waste rock (dilution) in concentrator feed as dilution can vary from 5-40%. RC grade control is the most cost-effective and accurate way to define boundaries between waste rock and ore bodies.
