Technical analysis of Brandy Hill South to steer low-cost exploration of the copper-gold project
Project has potential for higher grade porphyry-style copper mineralisation
Recharge continues to advance its Canadian lithium and uranium portfolio, with field work ongoing
Special Report: Recharge Metals is revisiting its Brandy Hill South copper-gold project in WA’s Mid West with technical analysis of historical data to drive exploration efforts.
Brandy Hill South is located within the Archaean Gullewa Greenstone Belt in WA, ~50km north-east of Morawa.
That’s the same belt the long-running Deflector copper-gold deposit is on, currently owned and run by Red 5 (ASX:RED).
Recharge Metals (ASX:REC) acquired Brandy Hill South from Revolution Mining during 2021. Prior to this, drilling within the project had been restricted to reconnaissance rotary air-blast and aircore drilling, along with just five shallow reverse circulation drill holes.
Drilling in 2007 by Independence Group (ASX:IGO) targeting copper anomalism intersected a zone of strong copper-gold-silver mineralisation, including 1m at 2.15g/t gold, 112g/t silver and 2.10% copper, within a broader interval of 12m at 1.10% copper.
That’s a decent hit, however IGO dismissed the idea of following up as it was looking for nickel at the time.
Recharge’s past drilling
Recharge completed an extensive drilling program at Brandy Hill South during 2021 and 2022, punching 20 RC drillholes and one diamond hole plus eight diamond drillholes with RC pre-collars across 6710m.
Results included 77m at 0.35% copper from 209m and 24m at 0.55% copper from 48m.
Compiled results show copper mineralisation over a 500m strike length that remains open in all directions.

Another high-grade copper porphyry in the Mid West?
A technical review of Brandy Hill South by highly regarded geologist Dr Steve Beresford incorporated visual logging, pXRF data, laboratory assay results from REC’s previous drilling programs and Tornado micro XRF imagery of drill core.
Inspection of drill core and assay data from Brandy Hill South supports the presence of the characteristic potassic and propylitic alteration haloes which are associated with porphyry systems.
Based on those findings, Dr Beresford believes there’s potential for higher grade porphyry style copper mineralisation at Brandy Hill South.
“Dr Steve Beresford’s technical review arose from our desire to put new eyes on Brandy Hill South while our recent focus was on critical and strategic minerals in North America,” REC MD Felicity Repacholi says.
“We are encouraged by Steve’s observations and findings, which has provided a relatively simple low-cost work program to advance the project.
“Copper is one of the key commodities in the global energy transition yet there are relatively few new projects which have emerged in recent times.
“Should exploration be successful, we anticipate substantial interest in Brandy Hill South going forward.”
Multiple copper porphyries exist around WA’s Mid West and Wheatbelt regions, such as the 3Mt Caravel deposit near Calingiri.
