Diamond drilling intersects gold mineralised quartz veining – breccia over a strike length of 750m at the Hampyeong Gold Project.
A maiden diamond drilling program has been completed at Southern Gold’s 100 per cent owned Hampyeong gold project in South Korea. Drilling is located on the Naju 136 graticule (tenure block) that was recently granted to Southern Gold. This area hosts the A’Cha, Nabi and Saseun epithermal quartz vein zones. No prior drilling or systematic exploration has occurred in the area prior to Southern Gold’sexploration efforts. Gold targets were outlined by rock chip sampling and geological mapping completed in mid-2017 with this round of drilling targeting the A’Cha and Nabi quartz veins hosted within Cretaceous volcanic rocks and a granitoid.
Drilling intersected gold mineralisation in all three holes with a peak result of 0.95m @ 5.33 g/t Au from 32.6m from the Nabi Vein Zone.
Drilling has been conducted with environmental and social considerations, including consultation with the local village, noise reduction measures and monitoring, sediment traps and pre-approved documented rehabilitation plans submitted to local council. The approval for the program required a pre-drilling report with registered surveyors documenting land clearance and proposed rehabilitation programs and forms part of the permitting processes.
Broad intervals (>10m) of A’Cha quartz vein breccia and anomalous gold were intersected in all three drillholes (Figures 3, 4 and 5). The A’Cha vein is a deep-level, low-sulphidation epithermal quartz vein and vein breccia system hosted predominately by sericite-illite-pyrite ± silica altered felsic volcanics and volcanoclastics. Vein textures indicate multiple phases of vein development and hydraulic brecciation with minor pyrite and trace sphalerite and galena present in certain phases of veining. The peak gold result returned from drilling of the A’Cha vein zone was 0.70m @ 2.47 g/t Au from 119m in HPDD003 with the vein open in all directions.
The secondary drill target was the Nabi vein zone that has peak surface rock chip results of up to 13.4 g/t Au. Drillhole HPDD003 successfully intersected the Nabi quartz vein down-dip of surface exposure, returning 0.95m @ 5.33 g/t Au from 32.6m downhole. The Nabi vein is an epithermal quartz vein and vein breccia hosted system within a silica-sericite-clay altered granitoid. The Nabi vein remains open in all directions, and additional core samples are being taken to confirm the potential extents of mineralisation into the hangingwall and footwall to the veins.
The initial three-hole scout drill program has confirmed the continuity of quartz veining mapped and sampled at surface, and the overall significant strike extent as well as the down dip continuity. The majority of results returned from the A’Cha vein show wide intervals of sub 0.5 g/t Au, confirming the kilometre-scale structure is anomalously mineralised. All veining intercepted remains open along strike and down dip. Potential future work at the Hampyeong project will focus on further drill testing the Nabi and A’Cha veins along strike and down dip, and first-round drill testing of the Saseun vein that outcrops about 4m wide and reports surface rock chip results up to 6.8 g/t Au.
