Southern Gold has used 3D modelling of mapped and sampled quartz veining at its Kochang underground mine in South Korea, to generate an exploration target of between 500,000 and 700,000 tonnes with a grade range between 5 and 7g/t gold and 27 - 35g/t silver. The company’s JV partner, Bluebird Ventures, is finalising its feasibility report on the reopening of the historical mine.
