Exploration targets †
The potential quantity and grade of an Exploration Target is conceptual in nature. There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. Ranges are shown exactly as the issuer disclosed them and are never added to the resource figures above.

Company notes
Renamed from GTI Energy (ASX ticker GTR became AMU from 29 Aug 2025). Lo Herma MRE grew to 9.96 Mlb in Aug 2026 with the Indicated category up 72% ahead of the scoping study; the issuer homepage still shows the superseded 8.57 Mlb figure, so the filed ASX PDF is cited instead. source
