Grade control drilling and stoping (mining of the ore) take place along the lateral development drives. This provides material samples used to determine the exact grade and nature of the ore. A development cycle of drilling, blasting, bogging and ground support is used to develop the tunnels. Blasting is required to fragment (break up) the rock
