Recent surface mapping and sampling conducted by Southern Gold at the Weolyu and Kochang projects in South Korea has identified large-scale mineralised systems. The work was completed by field mapping teams deployed at each project during March and April to build on programs completed at the end of 2016.
Detailed mapping at Weolyu by an expert in volcanic rocks and epithermal systems has been completed. Results continue to show epithermal-style gold-silver mineralisation peripheral to the historic mine.
Surface samples returning up to 8.8 g/t gold and 1030g/t silver after surface mapping has doubled the Weolyu mineralised corridor to 1km. The corridor was extended to the northeast and it remains open in this direction.
Several high-grade sample result have been returned from the northern end of the structural corridor where there has been limited or no mining activity and no historical drilling.
While the mineralised system at Weolyu has been extended laterally to kilometre scale, there is an implied vertical extent of mineralisation approaching 300 metres owing to the evidence of historical underground mining at Weolyu North.
Weolyu continues to be a focus for ongoing exploration, including surface drilling, which is in progress, and underground works, subject to approvals, where it is hoped that access to the underground drives will provide valuable technical information on the high-grade mineralisation.
The first diamond hole at Weolyu South was completed to 240 metres and this is now being logged and sampled. Zones of quartz veining and breccia have been intersected but assays remain pending.
New detailed mapping and sampling at Kochang confirms the continuity at surface of parallel veins along a 2.5km structural corridor of interest, from Kochang East and Kochang Gold Mine, through the Kochang Gap to the Kochang Silver Mine in the southwest.
Surface sampling returned up to 23.9 g/t gold and 650 g/t silver and identified multiple quartz veins across a structural corridor 2.5km long and about 0.5km wide. The results add further evidence that the Kochang Gap area is a prime drilling target, especially in the context of mineralisation grades encountered a depth in historical underground drives.
Future work will likely include a combination of surface drilling along strike and underground works, subject to approvals, including mapping and sampling the area of historical high-grade results.
