Twenty Seven Co Ltd (ASX:TSC) has extended shallow gold mineralisation over a 180-metre strike length during recent reverse circulation (RC) drilling at Harmonic prospect within the Rover Project in Western Australia.
At this stage of exploration, the company is encouraged to have high-grade shallow gold discoveries at the Harmonic and Creasy-1 prospects, which are just 500 metres apart.
Of the 20 RC drill-holes completed for 1,752 metres, the remaining nine assays will provide more clarity on the shallow high-grade gold discovery at Creasy-1 prospect.
Once all assays and ground electromagnetic results are received, TSC expects to progress further follow-up RC drilling later in the current quarter.
“Two high-grade discoveries”
Chief executive officer Ian Warland said: “The real surprise from these initial assays is discovering gold at surface and the extent of shallow high-grade gold mineralisation at the Harmonic prospect.
“There is now clear confirmation that gold mineralisation extends over 180 metres along strike, remaining open down dip and along strike.
“More importantly, TSC now has two high-grade gold discoveries 500 metres apart, that can be further explored.
“Looking forward, the remaining nine assays which are due shortly will provide more clarity on the extent of shallow gold mineralisation at the Creasy-1 prospect at two high-grade focus areas.”
Significant intersections include:
- 6 metres at 2.9 g/t gold from 44 metres including, 3 metres at 4.9 g/t from 44 metres, 3 metres at 5.5 g/t from 59 metres and 3 metres at 1.1 g/t from 32 metres;
- 5 metres at 1.3 g/t from surface;
- 3 metres at 1.4 g/t from 26 metres;
- 3 metres at 1.9 g/t from 77 metres, including 3 metres at 1.4 g/t from 101 metres;
- 9 metres at 1.4 g/t, including 1 metre at 7.25 g/t from 58 metres; and
- 14 metres at 1 g/t, including 2 metres at 3.3 g/t and 21.2 g/t from 26 metres.
Exploration at Rover is continuing with the key items over the next quarter including:
- Ground electromagnetic surveys over selected airborne electromagnetic targets underway;
- Assaying and interpreting remaining nine RC drill-holes from the March 2020 drilling campaign; and
- Planning follow-up RC drilling later in the current quarter.
