Golden Chest – Underground Mining
With the resumption of underground mining in late-2017, NJMC now operates two mines at its Golden Chest property, with all mined ore shipped to its nearby New Jersey Mill for processing.
A total of 4,260 tonnes were mined during the startup phase of underground mining operations in 2018. The average grade of the underground material was 7.0 gpt Au. The first stope was cut on the 851 level was completed in mid-2018 with commissioning of the cemented rockfill (CRF) backfill plant and backfilling was completed by the third quarter of 2018.
The Company added equipment to support the ramp-up of underground production and purchased two diamond core drill rigs for planned exploration and development drilling in the Murray Gold Belt.
