Twenty Seven Co Ltd (ASX:TSC) has completed a reverse circulation (RC) drill campaign comprising 31 holes for a total of 2,161 metres at the Rover Gold Project in WA.
Hole 21RVRC022 intersected a 4-metre zone of massive sulphides (pyrite and pyrrhotite) from 62 metres downhole within a 7 metres zone of disseminated sulphides.
The massive sulphide intersection indicates the potential for Rover to host volcanic-hosted massive sulphides (VHMS) targets, particularly given local/regional geology, which includes Cobre Ltd (ASX:CBE)’s Perrinvale project about 30 kilometres to the south.
A total of 574 samples will be submitted to the laboratory this week and the results are expected to be returned in the first quarter of 2022.
“Encouraging intersections”
Twenty Seven Co Ltd (ASX:TSC) CEO Simon Phillips said: “We are pleased to have completed this drilling program at Rover ahead of the Christmas break, as it allows us to submit our samples to the laboratory this week for processing.
“We expect to receive first results in around 5-6 weeks’ time and look forward not only to delineating further gold mineralisation but also to the results of assays for Hole 21RVRC022, given its encouraging intersection of a four metre-wide zone of massive sulphides.
“This program was focused on testing bedrock geochemical signatures identified from the most recent gold-in-soil sampling, with the aim of potentially extending known gold mineralisation at the Harmonic (NASDAQ:HLIT) and Creasy 1 prospects.
“I would like to thank our drilling partners at Ausdrill, along with TSC’s technical staff, for their effort and hard work to complete this program before Christmas.
“I look forward to providing further updates on exploration early in the New Year.”
Rover Gold Project drilling
The program consisted of 31 RC holes, of which six holes were designed to extend the Harmonic prospect, a priority target, at depth and along strike, and the remaining 25 holes were to test the gold-in-soil anomalism identified in November 2020 at Middle Well, Four Corners and Blue Hills.
Initial geological observations at Harmonic are in line with expectations, with mafics and quartzites having been intersected in all holes.
Geology at the Middle Well, Four Corners and Blue Hills prospects consisted mainly of mafic basalts/dolerites (with some potential ultramafics), granites and BIFS/SIFS.
Next steps
Its planned operational activities for the first quarter of 2022 include:
➢ Rover Gold Project, WA
- Receipt of RC assays from Rover drilling and detailed review; and
- Review of additional surface geochemical samples identified from WAMEX and incorporation of data into the Rover database to plan further infill geochemical samples, if required.
➢ Midas Project, NSW: Drill program implementation
➢ Perseus Project, NSW: Orientation surveys and soil sampling
➢ Yarbu Project, WA: Infill auger drilling program, potentially followed by later aircore drilling.
