  9. Slide 9: South African Assets – Free State

    South African Assets – Free State • Five permit areas totalling 395,890 acres in the Free State South Africa • A unique geological history 2 billion years in the making has created a truly exceptional opportunity • The end result is a world class helium and biogenic methane province with evidence of

  10. Slide 10: Exploration Right (ER315)

    Exploration Right 315 (ER315) d3energy.com.au | 10

  11. Slide 11: ER315 – Excellent initial results

    ER315 – Excellent initial results • Measured helium concentrations of 4.7% to 6.2% confirm world class potential – helium concentrations of less than 1% commercial elsewhere • Well’s free flow gas to surface – negligible pressure, no produced water, no downhole equipment…NO ISSUES! • Legacy borehole

  12. Slide 12: ER315 – Flow test results

    ER315 – Flow test results • Excellent flow rates measured in new and legacy gold exploration boreholes • Peak gas rate for RBD10 of 310msfcd • Measured permeability and interference between wells in all tests indicates very good reservoir quality and connectivity • Legacy boreholes that have been fl

  13. Slide 13: ER315 – The Enigma that is a Conundrum that is…

    ER315 – The Enigma that is a Conundrum that is… RBD10 Production Testing • Retesting confirms the truly UNIQUE characteristics of this reservoir • RBD03 & RBD10 measured an incredible 32% & 38% respective increase in flow rate August 2025 after retesting following a 12-month shut in August 2024 • Hi

  14. Slide 14: ER315 – Maiden Reserve Certification

    ER315 – Maiden Reserve Certification • Reserves ONLY for Production Right application (PRA) area • PRA is less than 9% of total area of all permits and reserve area is significantly smaller again • Does not take into account the Ventersberg Fault or any additional faults in between where gas is curr

  15. Slide 15: Low cost – high return wells

    Low cost – high return wells • High helium concentrations at current gas rates = high potential well profitability • Methane is a valuable commodity in its own right in energy starved South Africa • Wellhead (no processing) payback periods of months not years!
