Twenty Seven Co. has completed a 335-hole auger drilling program at its wholly-owned Yarbu gold project, following up previous gold in soil anomalies. Assay results are awaited from the 348 samples taken during the auger program.
Drilling targeted zones with more than 20 parts per billion gold in soil where combined lead-zinc values were also anomalous. The highest priority target was a gold in soil anomaly with dimensions of 1.9 km by 1.4km returning gold results up to 164 parts per billion.
The auger drilling program was designed to test and infill bedrock geochemical signatures identified by the company in April 2021.
The Yarbu gold project consists of three exploration licenses covering 223 square kilometres situated approximately 160km northeast of Southern Cross in Western Australia. The project is located on the Marda Greenstone belt, that the company considers highly prospective for Archean gold deposits.
Yarbu is located adjacent to Ramelius Resources’ Marda gold project, that Twenty Seven Co. describes as largely unexplored.
Management says the program was completed on time and budget with the exploration undertaken with a low environmental impact Landcruiser mounted auger drilling rig and samples were taken from an average depth of approximately 1.5m. Assays will be done using a low-level ultrafine fraction technique that delivers highly-sensitive analysis of gold and a broad suite of other elements.
After receiving assay results from the campaign, the company intends to identify areas of mineralisation for follow-up exploration. Assay results are not anticipated until late May.
Twenty Seven Co. has follow-up exploration programs underway, or planned, at its remaining projects in WA and NSW. Near Broken Hill the company is undertaking soil and rock chip sampling over three projects, the northern end of Perseus, southern end of Trident and eastern side of Midas. The key target is iron oxide copper-gold, or IOCG, mineralisation similar to the large Olympic Dam, Prominent Hill and Carapateena copper-gold deposits across the border in SA.
At the Mt Dimer gold project Twenty Seven Co. is assessing exploration options.
Rover is a wholly-owned gold and base metals project near Sandstone in WA covering 460 square km of tenure. It is two linear Archean greenstone belts with a combined length of approximately 160km. The company is waiting for final multi element and 1m results before designing the next phase of exploration.
Commenting on Yarbu, Twenty Seven Co. Chief Executive Simon Phillips said: “With gold mineralisation already confirmed across three broad areas within the project area, we are looking forward to receiving the outcomes from this program before we refine our deeper drilling targets which we aim to test later this year. We have a busy pipeline of activity planned for the coming months and we look forward to updating the market in due course.”
With large ground positions in lightly explored and lesser-known Archean greenstone belts in WA and joining the search for IOCG mineralisation near Broken Hill in NSW, there should be plenty of news flow in the coming months.
