Great Result From First Diamond Hole
Great Southern Mining (ASX: GSN) has encountered visible gold bearing mineralisation in diamond drill core from the Cox’s Find gold project in Western Australia.
Chief Operating Officer, Mark Major, said hole 20CFRCD0004 was drilled immediately down plunge from the known historic Cox’s Find workings and was designed to intersect an area of known high-grade mineralisation that has previously been identified from the recent 2019 December drill campaign.
“This is a very exciting time for the company – seeing multiple occurrences of visible gold in drill core is always a good sign,” Mr Major said.
“I’ve personally driven up to site to inspect the core. This is the first diamond core that has been drilled through the mineralised sequence and gives an invaluable insight to the geological setting and the potential existence of high-grade mineralisation.
“The geological team are processing the core now, to get as much information as possible from the core in order to understand the structural orientation of the mineralisation and to unlock the geological model to aid future drill campaigns.”
Hole 20CFRCD0004 was designed to target the recently discovered unmined high-grade panel of mineralisation intersected between level five (132 metres below ground level) and level six (158 metres below ground level) of the underground development to gain an understanding of the structural controls of the high-grade mineralisation.
Highlights of the 2019 drilling included the following standout intersections in this panel:
- 19CFRC009 – 5m at 14.54 g/tgold from 140m, including 2m at 28.85 g/t.
- 19CFRC013 – 5m at 31.23 g/tgold from 134m, including 1m at 143.0 g/t.
- 19CFRC004 – 2m at 36 g/tgold from 146m, including 1m at 68 g/t.
Two diamond drill holes have been drilled since diamond drilling commenced on the 17 June 2020. Processing of the diamond core is underway, and first core is expected to be cut and sent for assay within the week.
The initial diamond drill hole, 20CFRCD0002, intersected an unmapped historical stope at 159.3m and will be processed and assayed after 20CFRCD0004. Three remaining diamond holes are planned to be drilled from the current phase of diamond drilling with two of these holes planned down plunge from 20CFRCD0004.
Approximately 4600m of RC drilling has also been completed to date with 504m of this accounted to the pre-collar component for the diamond drill programme. This first phase of RC drilling has focused on delineating the extent of the high-grade mineralisation around 20CFRCD0004 and the potential down plunge extents of the Cox’s Find deposit.
A scout (414m) RC programne was also completed at one of the near mine untested geological ‘look-alike’ targets.
Assay results for all RC drilling are pending with results to be released to the market once received and interpreted.
Phase two will consist of approximately 4000m of RC drilling, focusing on several other near mine targets and following up on results from the initial phase.
