Slide 8: What is it?
What is it? • Helium was first detected in 1868 as a bright yellow spectral line in sunlight by astronomer's Pierre Janssen and Norman Lockyer • It was discovered on Earth 26 years later Helium is ONLY generated by natural radioactive decay of Uranium and Thorium and while being the second most abun

Exploration Right 315 (ER315) d3energy.com.au | 13
Slide 14: 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
Slide 15: A truly unique reservoir…
A truly unique reservoir… RBD03 Production Testing June 2025 August 2024 • Higher pressure and flow rates after being shutin for 12 months can only imply continual recharge of helium and biogenic methane at depth The result of re-testing more than 12 months apart is the paradox of HIGHER NOT LOWER r
Slide 16: Maiden Reserve Certification
Maiden Reserve Certification • Reserves ONLY for part of Production Right application (PRA) area • Does not take into account the Ventersberg Fault or any additional faults in between where gas is currently flowing from legacy gold exploration boreholes Reserve (BCF) 1P 2P 3P Gross Reserve 7.21 14.4
Slide 17: 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!
