Mining and Processing

The mining method used for the FS is Long Hole Open Stoping (LHOS) with ribs and sill pillars to consistently sustain the production and mill throughput design rate. Required infrastructure to support the mine operation have been included in the design, including all materials handling equipment. Trucking and mobile equipment have been optimized in the mine design along with implementation of conveyors for both crushed ore and waste.

Underground mobile crushers are utilized followed by a grinding circuit including a semi-autogenous grinding (SAG) mill and a ball mill located on surface prior to flotation. The concentrate is filtered using a plate and frame pressure filter and stored in a storage warehouse prior to shipping through the existing and operational port and ship loaders. The mine and process facility will be powered by an existing 132 kV power line. Fresh water requirements for the process plant and the mine will be provided from an existing water dam using an existing buried pipeline. A water treatment plant has been included to treat the underground mine water to a quality suitable for reuse within the processing plant, thereby reducing demand for freshwater abstraction from the water reservoir and to treat the excess mine water to a quality suitable for controlled discharge during upset conditions (e.g. processing plant shutdowns or maintenance), in accordance with applicable Norwegian and EU environmental standards.
