Construction and Pre-Production Mining

Open pit mining has been initiated in our starter pit phase. Excavated waste material will be used for construction purposes, as a source for aggregate, and fill material for constructing the dam of our tailings facility. During the pre-production, it is planned to stockpile approximately 2.4 million tonnes of ore prior to commissioning (~6 months of ore mill feed).
