ASX ANNOUNCEMENT
Additional high-grade copper gossans identified at Baratta
Highlights
-
The latest rock chip assays identify a significant third parallel copper-bearing gossan extending the eastern extent of the Baratta Copper Project.
-
New high-grade infill rock chip assays up to 22% copper reinforce the consistency of copper-grade along the mapped 3.6 kilometres strike of multiple stacked copper-rich gossans.
-
Ongoing exploration work includes geological mapping, sampling, geophysical re-processing and petrological examination of primary sulphide-bearing breccias from Baratta mine waste.
-
Baratta’s geological setting displays characteristics Stelar considers similar to those seen in the Central African Copper Belt, the world’s second-largest copper-producing province.
Stelar Metals Limited (ASX:SLB) (“ Stelar Metals ” or “ the Company ”) has identified a third parallel copper mineralised gossan to the east of the Baratta Copper Project. Additionally, infill rock chips also emphasise the consistency of the high-grade copper grades along the strike of the stacked stratabound gossans ( Figure 1 ).
Baratta is considered highly prospective consistent for Sediment-hosted Stratabound Copper (SSC) mineralisation analogous to the Central African Copper Belt (CACB).
The Baratta Copper Project has now been mapped and sampled for over 3.6 km along strike, which remains open in both directions. Each new discovery of parallel mineralised gossans multiplies the economic potential of this SSC Copper Project ( Figure 2 ).
Round 3 rock chip sampling at Baratta has again returned exciting results, with 27% of the samples assaying over 10% copper and 69% assaying over 5% copper ( Table 1 ).

Petrological examination of the primary chalcopyrite (copper-iron sulphide) mineralisation[2] observed in haematite-chalcocite-copper oxide breccias from shallow mine waste at Baratta is currently being undertaken by Microanalysis in Perth.
The historic Baratta Copper Mine produced copper ore between 1896 and 1904 from a 1.5 km-long zone of stratabound workings in a structure splaying off the major Bibliando Thrust structure.
Multiple parallel mineralised horizons of quartz-haematite gossan extend for several kilometres through Stelar’s tenements, coincident with a recently discovered large Induced Polarisation (IP) chargeable anomaly as it approaches the Bibliando Thrust.
Sediment-hosted Stratabound Copper (SSC) deposits are the world’s second most important source of copper and account for ~20% of the world’s copper production. In 2024, the Central African Copper Belt (CACB), which spans the Democratic Republic of Congo and Zambia, is positioned to be the second-largest global copper producer behind Chile's large porphyry deposits.

In Australia, only the Adelaide Rift Complex (Baratta) and the Sturt Shelf, both in South Australia, are considered prospective for this highly prized style of copper mineralisation. South Australia contains 69% of Australia's economic demonstrated copper resources and produces approximately one-third of Australia's mined copper.
Baratta Copper Project Geology
Located within the Adelaide Rift Complex, Stelar’s Baratta Project is hosted by NeoProterozoic Wilyerpa Formation sediments deposited in a shallow marine glacial environment. These sedimentary rocks have subsequently been folded, influenced by salt-diapirism and hydromorphic processes.
The stratigraphy comprises highly repetitious, cyclical facies of upwardly fining sequences with lower dolomitic sandstones transitioning through dolomitic siltstones into upper beds of dolomitic pyrite-bearing shales. Individual cycles vary but are typically 10-30 metres thick. Bedding geometries are generally planar and gently undulating, although lenticular interbedding occur in the middle of the cycles where facies overlap. The stratigraphy at Baratta, located on the northern flank of the Bibliando Dome, generally dips moderately to the north ( Figure 2 ).
Deformation resulted in zones of shale detachment at some of the contacts between the finergrained reduced shales and overlying, more resistive, dolomite-cemented basal sand units. These stratabound shear zones resulted in brecciation and complex alteration, including the introduction of copper and iron, associated with focused fluid flow from basin dewatering basin during metamorphism.
The Fe-Cu brecciated gossans mapped at surface appear concentrated in the planes of these altered shale detachments, replacing original shale beds and extending upwards in smaller structures, as micro-brecciation, up into the contact with the overlying sand units as mineralised veinlets and vugs. In some areas, cross-cutting structures have facilitated more extensive migration of copper-bearing fluids into immediately overlying cycles, resulting in localised “tree-like” structures ( Figure 3 ).
At surface, the stratabound gossans, which have been mapped up to five metres thick, extend for hundreds of metres to several kilometres along strike and, as illustrated by the conceptual section in Figure 2 , likely extend down-dip along these moderately dipping bedding planes at depth. The oxidised copper minerals such as azurite, malachite and chalcocite observed at surface are expected to transition to chalcopyrite-bornite facies down dip beneath the base of oxidation.

Next Steps
Geological mapping and rock chip sampling at Baratta will continue with the aim of discovering additional parallel gossans and mapping their strike potential. Where the strike-extensive gossans are terminated by modern drainage and cover, soil geochemistry and geophysics will be used to map offsets and continue the mapping.
Reconnaissance of other areas at Baratta, including the historic Lone Pine Copper Mine to the west of the Bibliando Thrust, has commenced and will be reported shortly.
Staged exploration of the broader Baratta Project, including the elongate Bibliando Diapir and the southern flank of the Bibliando Dome, will continue over the coming months.

ABOUT STELAR METALS
Stelar Metals’ experienced and successful exploration and development team is targeting the discovery and production of critical minerals, with increasing global demand to enable the world to achieve net zero emissions.
Stelar’s Trident Lithium Project is located near mining, industrial, transport and green power infrastructure at Broken Hill in NSW. The Trident Lithium Project extends over the 20km strike length of the Euriowie Tin Pegmatite Field and is highly prospective for hard rock lithium mineralisation. Mapped LCT-type pegmatites vary in size but can be up to 100 metres wide and extend in outcrop for over 1 kilometre in length. Trident was one of Australia's first lithium and tin mining provinces, highlighting both the fertility and large scale of Stelar’s lithium-rich pegmatite system.
Stelar’s Baratta Copper Project, located in South Australia, is hosted within the Adelaidean rocks of the Flinders Ranges. The Project is considered highly prospective for sediment-hosted copper mineralisation, akin to the Central African Copper Belt. The historic Baratta Copper Mine produced copper ore between 1896 and 1904 from a 1.5 km-long zone of strata-bound workings in a structure splaying off the Bibliando Thrust. Stelar is conducting exploration activities in a 7-kilometre corridor of copper mineralisation and geophysical targets that have been overlooked by previous explorers.
EXPLORATION RESULTS
The information in this announcement related to Exploration Results is based on information compiled by Mr Colin Skidmore, a Competent Person who is a Member of the Australian Institute of Geoscientists. Mr Skidmore is a full-time employee of Stelar Metals Ltd. Mr. Skidmore has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration and to the activities being undertaken to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code (2012)). Mr. Skidmore consents to including matters in this announcement based on his information in the form and context in which it appears.
This announcement includes information related to Exploration Results prepared and first disclosed under the JORC Code (2012) and extracted from the Company’s initial public offering prospectus, which was released on the ASX on 16 March 2022. A copy of this prospectus is available from the ASX Announcements page of the Company’s website: https://stelarmetals.com.au/.
The Company confirms that it is unaware of any new information or data that materially affects the information in the relevant market announcement. Where the information relates to Exploration Results, the Company confirms that the form and context in which the competent person’s findings are presented have not been materially modified from the original market announcement.
