Mineral resources. Mineral resources are not mineral reserves and have not demonstrated economic viability. Inferred mineral resources have a high degree of uncertainty as to their existence and as to their economic and legal feasibility.

Feni Island technical report. The Kabang mineral resource is from the NI 43-101 Technical Report on the Feni Gold-Copper Property, New Ireland Province, Papua New Guinea, dated October 14, 2021, available under Adyton's profile on SEDAR+.

Gold equivalent. Gold equivalent (AuEq) = ((Au g/t × 0.93) + (Cu% × 1.71 × 0.90)), based on metal prices of US$2,000/oz Au and US$5/lb Cu, and recoveries of 93% Au and 90% Cu. Recovery assumptions are speculative as no metallurgical test work has been completed at Feni.

Lihir and other properties. Lihir, Simberi and other mines named here are owned by other companies. Mineralization on those properties is not necessarily indicative of mineralization at Feni.

Forward-looking information. This material contains forward-looking information, including drilling, survey and resource-update timetables. Actual results may differ materially. See Adyton's filings on SEDAR+.

Qualified person. Dr. Chris Bowden, PhD, GCMEE, FAusIMM(CP), FSEG, Chief Operating Officer and Chief Geologist of Adyton, is the Qualified Person as defined by NI 43-101 for Adyton's technical information.
