MED - Merlin Diamonds Provides Update to Trial Borehole Mining Operations
Merlin Diamonds announced an update to its trial borehole mining operations at the Merlin Diamond Mine in the NT. The borehole mining rig has been operating for over one month and has achieved success in a number of key areas. The hydraulic jetting tool that cuts the kimberlite material at depth has been proven to effectively cut the weathered kimberlite and is able to produce diamond bearing ore suitable for lifting via the mining rods. The hydraulic lifting system has been proven to lift material to the surface of the pit and is able deliver ore to the shaker screen located on the ground surface adjacent to the pit. The processing plant has also achieved nameplate capacity of 75t per hour. The company is now at a stage to complete engineering work that will increase this rate of production.
