Coronation North: 91 holes for 10,247 metres completed with a 50 metre x 50 metre drilling pattern and investigating potential extensions to the gold mineralisation to the north and southeast; Coronation open pit: six holes for 814 metres to follow-up on previous intersections; Coronation South: seven holes for 847 metres to investigate the potential for ore shoot repetition between Deepdell North and Coronation; Horse Flat: five holes for 386 metres targeting the Horse Flat Fault for a repetition of fault drag mineralisation seen elsewhere in the Macraes Goldfield; and Frasers Underground: 13 holes for 1,850 metres testing down plunge extensions and a sheeted vein target.
Currawong has identified significant exploration potential for mesothermal quartz vein hosted gold and related placer-style 'deep lead' gold mineralisation at Avoca, and epithermal 'Carlin' style disseminated or sheeted vein hosted gold mineralisation at Bailieston
Between 1980 and 1983 SWM followed up its initial exploration program with a detailed program of diamond drilling to a depth of 600 meters to test the extent of sheeted vein tin-tungsten mineralization at Redmoor.
Drilling intersected a sheeted vein system with silica and carbonate alteration.
It is clear the narrow sheeted vein style of the gold mineralisation defeated the old timer.
Other assayed samples (Table 2) of disseminated and sheeted vein mineralisation came from pits along the line of lode.
The sheeted vein nature of the mineralisation at Cuttaburra is also typical of intrusion-related gold systems.
Highlights from initial results in the South Zone, include hole UGCB19-147 which was drilled at minus 15 degrees to the north in the South Zone underground workings and intercepted a total of seven sub-parallel sheeted veins, including Vein VS_06 which assayed 11.2 g/t Au and 78 g/t Ag over 13.7 meters.
In addition to the aforementioned gold and massive sulphide targets, Romios' Lundmark-Akow Lake claims cover the shear zone-hosted Spence showing which returned grab sample assays in 1997 ranging from 0.358 to 38.6 oz/t Au from a blast trench in copper-mineralized sheeted veins. Soil sampling conducted in June 2019 revealed a prominent copper anomaly up to 1,660 ppm Cu over a linear magnetic low that flanks the mineralized outcrops.
Intensely skarnified and very densely sheeted veined metasediment is observed in the hole, from ~350m.
- - Assays up to 126g/t gold in sheeted veins to the east of the main Golden Hind vein.
Samples of sheeted veins collected from waste piles beside Diggers Shaft assayed up to 2.39 grams per tonne gold, 3.76 ounces per tonne silver and 0.85% lead per tonne.
