Helix Resources Ltd (ASX:HLX) has broadened its horizons, expanding the footprint of its Bijoux prospect following recent reverse-circulation (RC) drilling that confirms copper sulphide mineralisation along a 290-metre strike.
Bijoux, considered a CSA-style copper deposit, lies just nine kilometres south of Helix’s existing Canbelego mineral resource, within Helix’s Western Group tenements in the Cobar-Nyngan region of central New South Wales.
The deposit remains open at depth and along strike.
Strong, open copper
The drilling program, comprising eight RC holes amounting to 1,440 metres, intersected copper mineralisation in every hole, with notable assays including 2 metres at 2.92% copper within a 26-metre interval at 0.58% copper from 84 metres.
This recent expansion builds upon previously reported results, which included high-grade intersections such as 2 metres at 5.76% copper from 182 metres.
Helix now plans further RC and diamond drilling to explore depth potential and enhance structural understanding of the mineralised zone.
The discovery marks a key outcome of Helix’s extensive geochemical sampling across the Rochford Copper Trend, a 30-kilometre belt with historical copper prospects.
The Bijoux anomaly, measuring around 1.6 kilometres by 0.6 kilometres, was refined through targeted auger sampling before initial scout drilling in 2023.
Elsewhere, Helix continues active exploration across its tenements.
Auger sampling results are expected soon from the Muriel Tank historical gold field, while further exploration is underway in the Rochford Trend north of Canbelego and at the Cobar joint venture with Legacy Minerals.
Further discoveries ahead
Helix has also secured approvals for drilling at its Louis copper prospect and multiple gold-copper targets in its Eastern Group tenements, aiming to unlock further discoveries within the highly prospective Cobar Basin.
Helix managing director Kylie Prendergast said: “We are excited with the latest batch of assays from Bijoux which have delivered encouraging grades as well as significantly expanding the prospect’s strike length.
“The prospect remains open – both at depth and along strike – and we intend to follow these results with further drilling.
“Bijoux is a prime example of the experience and tenacity current management have applied to the company’s large-scale Cobar tenements.
“Having been identified and prioritised through a comprehensive geochemical program, the team have worked systematically via further auger and RC drilling to test our CSA-style copper model.
“Today’s assays validate this approach and continue to highlight that in an area as rich as the Cobar Basin, quality exploration means the company is potentially just one drill hit away from a new discovery.
"Pleasingly, the Helix team is also hard at work across our other prospects and we anticipate assays as well as further drilling at the Muriel Tank Gold Project, which continues to show considerable promise.
“A drill program is also prepared for the Louis copper prospect which has had no drilling to date and returned a cluster of geochemical copper anomalies.
“I look forward to keeping shareholders informed as the company continues to execute its strategy of unlocking new copper discoveries.”
