Twenty Seven Co is set to kick off reverse circulation drilling at its 100 per cent owned Rover gold project near Sandstone in WA next week that will test recent stellar soil sampling results including a 1.15 gram per tonne surface gold sample. Drilling will also test some exciting drill intersections at the Harmonic and Creasy prospects to get a better understanding of the potential scale of the mineralised system around them.
The 2,000 metre reverse circulation drill program, totalling approximately 31 holes, is focussed on two targets at the Rover gold project located 55 kilometres southeast of Sandstone in the Yilgarn craton in WA. Six of the 31 drill holes are designed to extend mineralisation both along strike and down dip of the previously identified Harmonic and Creasy prospects. The remaining 25 drillholes will test the bedrock below surface geochemical signatures identified in a recent soil sampling campaign.
The six drillholes designed to extend mineralisation along strike at Harmonic and Creasy will provide a better snapshot of just how big the mineralised system is. The drillholes are planned off the back of encouraging drill results identified from drill campaigns in 2019 and 2020 at Harmonic and Creasy. Some of the better hits include 10m grading at 1.84 g/t gold from 44m, 13m grading 1.2 g/t gold from 58m and 15m grading at 1 g/t gold from 6m in amongst a swathe of other enviable grades.
The second part of the drill program consisting of 25 drillholes has been designed to focus on results from a recent geochemical soil sampling program that returned the largest and highest magnitude gold-in-soil anomalies to date at the Rover project. These results eclipsed the soil anomalies associated with the discovery of the Creasy and Harmonic gold discoveries only 10 kilometres to the south which lends credence to the possibility of another deposit looming below. The drilling will target the boundary of quartzites and mafic units that lie within the Edale shear zone at the Blue Hills and Four Corners prospects.
Geochemical soil sampling has proven to be a highly successful method in defining gold anomalism at the Rover gold project and a further 300 soil samples will be undertaken with the aim of extending the gold-in-soil anomalism along the Edale shear zone to the north of the recent geochemical sampling results.
Twenty Seven Co’s chief executive officer, Simon Phillips said:
“Rover is in a highly sought-after exploration address and gives TSC a large strategic footprint in the Central Yilgarn prospective for Archean gold deposits. Previous work has already defined significant gold system from surface at the Harmonic and Creasy 1 Prospects, so we are eager to get this next phase of exploration underway”
Pundits will no doubt be keeping a close eye on the follow-up drill results at Rover as there is already a lot of smoke around the drill targets – now for some fire.
