Twenty Seven Co Ltd will shortly begin a follow-up auger drilling program at Yarbu Gold Project about 160 kilometres northeast of Southern Cross and 90 kilometres northwest of its 100%-owned Mt Dimer Gold and Silver Project in Western Australia.
Around 330 holes are to be drilled in and around the highest priority anomalies defined to date, including a large 1.9 kilometres by 1.4 kilometres anomaly with up to 164 parts per billion (ppb) gold in soil.
Previous anomalies highlight complex structural settings within the Yarbu tenements, with the broader Yarbu project area remaining largely underexplored.
“Potential targets for deeper drilling”
Twenty Seven CEO Simon Phillips said: “We are pleased to be back on the ground at Yarbu to further explore several anomalies identified across what remains a largely underexplored part of the Marda-Diemals Greenstone Belt.
“Our maiden auger program, completed in July 2021, confirmed gold mineralisation across three broad areas and this follow-up up program will aim to define potential targets for deeper drilling.
“We look forward to providing further updates on Yarbu and other opportunities within TSC’s exploration pipeline over the coming weeks.”
Drilling program
Local drilling contractor Gyro Australia has been reappointed to undertake the infill auger drilling campaign.
Drilling will utilise a low environmental impact LandCruiser-mounted auger drilling rig, which will drill to around 2-3 metres depth, depending on penetration across the areas of anomalisms previously reported.
All samples will be assayed at Lab West in Perth using their low-level UltraFine fraction technique, which was developed through CSIRO/MRIWA research project M462 and delivers highly sensitive analysis of gold and multi-elements in the ultrafine (<2µm) fraction of soil samples.
Full assays are expected to be received by late May 2022 due to the unprecedented backlog at all labs in WA.
Yarbu is in a highly prospective location along the Marda-Diemals greenstone belt, adjacent to Ramelius Resources Ltd’s Marda Gold Project
Next steps
The following work programs are underway and/or planned for the company’s WA gold portfolio:
➢ Yarbu Gold Project: Analyse pending assay results from the Yarbu auger drilling campaign and identify any areas of mineralisation/anomalism for follow-up exploration and drilling activity;
➢ Mt Dimer Gold and Silver Project: All options being assessed by the company; and
➢ Rover Gold Project: Awaiting final multi-element and 1-metre gold results. Results are due in the next few weeks due to the lab backlog in reporting assay results. Once these results are finalised further planning will be undertaken.
