Ann: Submission of 2D Seismic Approvals for EP145, page-2

EP145 2D Seismic Environmental Management Plan submitted to DEPWS.
• All remaining long-lead items ordered for the seismic program.
• Seismic data acquisition expected to commence in August, providing a key
dataset for Greenvale to target ultra-high-grade helium, hydrogen and
hydrocarbon resources within the highly prospective Amadeus Basin.
• EP145 represents an exciting opportunity for Greenvale to become a supplier to
the rapidly growing helium market, which is experiencing severe supply
shortages and strong demand growth and pricing.
• EP145 contains a reported Prospective Resource Estimate of 440 Billion cubic
feet (Bcf) of Total Gas including 26.4Bcf of Helium and 26.4Bcf of Hydrogen.
