Slide 1: EP-494 Prospectivity Update
ASX Release 5 June 2026 EP-494 PROSPECTIVITY UPDATE Highlights: • New seismic interpretation adds a significant oil prospect to the portfolio • Potential for oil and gas up-dip of existing wells with known oil shows • Three additional leads identified and currently being evaluated • Barberton 3D sei
Slide 2: Why the Barberton and Yarra Yarra Terraces are highly prospective
Why the Barberton and Yarra Yarra Terraces (and therefore EP-494) are highly prospective The eastern margin of the North Perth Basin was, for a long time, considered to be defined by a large single fault, the Darling Fault, which puts Permian reservoirs in the basin beyond the range of drilling capa
Slide 3: Three additional leads and hydrogen and helium potential
Three additional leads have been identified with technical studies ongoing. The Bowmore and Cardhu leads are Jurassic three-way closures and pinch-out traps downthrown to the Urella and Darling Faults whereas the Barberton East lead is a Triassic/Permian three-way closure against the Darling Fault,

Slide 7: Introduction
Introduction MACALLUM NEW ENERGY CONTINUES TO ADD TO ITS PORTFOLIO OF EXPLORATION OPPORTUNITIES • Macallum New Energy (MNE) is on track with its oil & gas exploration work program with the Barberton 3D seismic survey complete and the Condor 2D survey days away from completion • While waiting for pro
Slide 8: EP-494 Petroleum Potential
EP-494 Petroleum Potential UNDEREXPLORED WITH HIGH POTENTIAL • EP-494 is a large permit of 2,577 km2 • Located in the underexplored southern part of the prolific North Perth Basin • Adjacent to Warro and Gingin gas fields in a proven petroleum system • Highly prospective for oil and gas with multipl
Slide 9: New Prospects and Leads in EP-494
New Prospects and Leads in EP-494 RECENTLY RELEASED SEISMIC DATA PROVIDES NEW INSIGHTS TO EP-494 ADDING TO EXPLORATION POTENTIAL • Ongoing interpretation of all available data in the permit has identified a significant new oil/gas prospect in EP-494, Aberfeldy Prospect, and three new leads which req
Slide 10: Aberfeldy Prospect
Aberfeldy Prospect STRUCTURAL TRAP WITH POTENTIAL FOR OIL AND GAS, UP-DIP OF KNOWN OIL DISCOVERY • 16km2 fault-bound structural closure up- Dandaragan Deep-1 dip of Dandaragan-1 (Discovery Dandaragan-1 Aberfeldy Petroleum, 1995) and Dandaragan Deep-1 (MinRes, 2025) • Dandaragan-1 encountered oil at
Slide 11: Additional Leads in EP-494
Additional Leads in EP-494 THREE ADDITIONAL LEADS IDENTIFIED IN EP-494 • Significant upside potential remains in the permit with multiple leads and prospects in the portfolio to follow-up from a successful well that proves the Jurassic play in EP-494 • Work is ongoing to mature additional Jurassic l
Slide 12: EP-494 Prospective Resources
EP-494 Prospective Resources SUMMARY OF UNRISKED PROSPECTIVE RESOURCES (EXISTING PROSPECTS & LEADS) IN EP-494 • Barberton Terrace Deep (BTD): Drill-ready Kingia prospect • Large un-drilled Permian structures identified with a mapped area estimated to be ~100km² • Preliminary exploration well locatio
Slide 13: Renewed Interest in the Jurassic play
Renewed Interest in the Jurassic play SIGNIFICANT NEARBY ACTIVITY IS REVITALISING THE SUCCESSFUL JURASSIC PLAY • Well established play type with multiple fields and wells throughout the basin • Walyering Field (Strike Energy) proves Jurassic Play commerciality : 2P Reserves ~ 60 Bcf. Gas plant size:
Slide 14: The Underexplored South
The Underexplored South THE SOUTHERN PART OF THE PERTH BASIN IS VASTLY UNDEREXPLORED NORTH SOUTH • Approx 8,400 km2 under • Approx 11,500 km2 under permits permits • 321 Petroleum wells drilled • 53 Petroleum wells drilled • 1 well per 26 km2 • 1 well per 217 km2 • Dense 2D and 3D seismic • Sparse 2
Slide 15: Perth Basin Petroleum System
Perth Basin Petroleum System SAME PETROLEUM SYSTEM AS THE NORTH BUT BETTER POSITIONED Same hydrocarbon source rocks. • EP-494 sits directly over the source “kitchen” where source rocks are mature for gas at present day. Better location than northern fields where long-distance migration is required S
Slide 16: Barberton and Yarra Yarra Terraces
Barberton and Yarra Yarra Terraces EP-494 UNIQUELY SITS OVER A SERIES OF TERRACES PLACING RESERVOIRS AT MORE FAVOURABLE DEPTHS • Barberton and Yarra Yarra Terraces put Jurassic targets ~2,000m shallower than every other well in adjoining permits = better reservoir quality and cheaper wells • Barbert
Slide 17: Helium & Hydrogen Potential
Helium & Hydrogen Potential EP-494 HAS CONFIRMED POTENTIAL FOR HELIUM AND NATURAL HYDROGEN • On 28 May 2026, the WA government implemented new regulations to allow petroleum permit holders to include regulated substances into existing licenses, including helium and natural hydrogen • MNE intends to
Slide 18: Helium Potential in EP-494
Helium Potential in EP-494 EP-494 POSITIONED DIRECTLY ABOVE A POTENTIAL CONDUIT FOR HYDROGEN & HELIUM • Northern area has surface expressions commonly associated with natural hydrogen seeps • A sub-soil gas sampling survey was conducted in 2022 by researchers from Curtin University. The peer-reviewe
Slide 19: Summary
