Twenty Seven Co’s plans to increase the size of the gold mineralisation at its Rover gold project in WA’s Central Yilgarn region look to be on track after completing an RC drilling program that showed good continuity along strike and down dip from previous gold-yielding drilling.
The company says one metre splits from 4m composite gold assays confirmed shallow gold mineralisation with a total of 42 of the 141 one-metre samples returning greater than 0.1ppm gold.
Whilst initial gold composites results from the 4m cores were reported in February, the new detailed 1m results from the drilling campaign have further highlighted the potential mineralisation of the Rover project area, and in particular at its wholly-owned Harmonic prospect.
The Rover project is a large 460 square kilometre spread covering two linear Archean greenstones, with a combined length of around 160km. Management said historically the area is underexplored and is currently undergoing a resurgence in exploration.
Highlights from the one-metre splits include grades going 1m at 1.94 grams per tonne gold and a broader interval of 6m grading 0.40 g/t gold. The result underlines the continuity along strike and down dip of the previous holes drilled by the company in 2019 and 2020, work it says highlights the strong mineralised potential at Harmonic and across the broader Rover project area.
Twenty Seven Co Non-Executive Chairman, Rohan Dalziell said: “We are continuing to build our understanding of the mineralised system at Rover and the confirmation of further shallow gold mineralisation is encouraging as we plan our future work programmes in the area.”
The company added it would wait for the final multi-element results to come in from the Rover RC drilling program before refining its next round of exploration activities.
It is also waiting on assay results from auger drilling at its Yarbu project, located on the Marda-Diemals Greenstone belt, adjacent to Ramelius Resources’ Marda gold project, an area Twenty Seven believes is highly prospective for Archean gold deposits. The results will identify areas of mineralisation and anomalies for follow-up exploration work.
Twenty Seven Co also says all options for its Mt Dimer acreage are being looked at after recent soil geochemical sampling to the west of its licence showed potential for further mineralisation within the greater project area.
In addition to its WA acreage, Twenty Seven Co is maturing iron oxide copper gold, or ‘IOCG’, targets in NSW around the Broken Hill area. It has the Midas, Perseus and Trident projects where it is planning a soil and rock chip sampling program over all three leads.
