Recharge Metals to commence drilling at Brandy Hill South copper-gold project
Three holes of Recharge Metals’ ongoing drilling campaign were terminated in visual copper mineralisation.
Recharge Metals (ASX: REC) has commenced a 2,000 metre reverse circulation drilling campaign at the Brandy Hill South copper-gold project within Western Australia’s Murchison Province.
The campaign has been designed to complete pre-collars for diamond tails to then test down hole transient electromagnetic (DHTEM) conductors as well as anomalous historic copper results along strike of the current target area.
Five diamond holes will focus on two strong off hole conductors identified from earlier drilling which were logged at 2,400 and 7,000 siemens.
West Core Drilling has been contracted to carry out the diamond drill work, with the rig mobilising to site this week.
Resuming exploration
Recharge managing director Brett Wallace said crews were pleased to be starting exploration at the project.
“We are very excited to resume drilling at Brandy Hill South to test a DHTEM conductor and anomalous historic results and to prepare pre-collars,” he said.
“More importantly, diamond drilling will be carried out to target strong off hole electromagnetic conductors and to further test the strike and depth extensions to mineralisation.”
Magnesium basalts
In March, diamond drilling intersected ultramafic, high-magnesium basalts to end-of-hole at the project.
Massive sulphide, brecciated zones of semi-massive sulphide and disseminated visual copper sulphide mineralisation were observed from 92m.
Drilling also intersected intense hydrothermal alteration including carbonate, chlorite, epidote, quartz and sericite across the lithological sequence.
Brandy Hill South acquisition
The historic Brandy Hill South project is located in the Archaean Gullewa greenstone belt within the Yilgarn Craton and was acquired from Revolution Mining last year.
In 2019, Revolution drilled three shallow reconnaissance holes aimed at “proof of concept” testing of the inferred strike of the Salt Creek Shear and subsidiary geological structures beneath the cover.
All holes were reported to have intersected copper sulphide mineralisation over a substantial strike length.
Recharge acquired the project based on the exploration potential of the Salt Creek Shear, which runs north-south and deforms the belt on a regional scale.
The principal target is volcanic-hosted massive copper-zinc sulphides within the felsic volcanic sequence of the Windaning Formation which is concealed beneath up to 65m of unconsolidated quaternary sand.
