_______________

Osmond Resources Limited (ASX: OSM) (Osmond or the Company) is pleased to confirm detailed geological logging of the first drill hole (AV-01; Table 1) has been completed at the Orión EU Critical Minerals Project (Orión or the Project) (Figure 1). As announced in the ASX release on 7 October 2025, the targeted prospective stratigraphy, specifically the Ordovician Pochico Formation, was intersected.

Following geological and geophysical logging, the Company can now confirm that the entire drill hole intersected the Pochico Formation with the hole terminating in massive quartzites of the Lower Member of the Pochico Formation at 187.8m depth (Table 1).

The Company makes no representations with respect to mineralisation.

The Pochico Formation has been mapped throughout the Project area and is characterised by containing multiple layers enriched in heavy minerals. Within the Orión Investigation Permit (P.I.), heavy mineral prospective layers have been mapped and sampled by Osmond across a minimum three (3) prospective zones and have been shown to be highly anomalous in the critical and strategic minerals rutile, zircon and monazite. Heavy Mineral concentrations up to ~33% have been recorded by bulk channel sampling in Zone 1 (Table 3) (refer ASX release dated 6 September 2024, 28 January 2024 and 20 June 2025).

Geological logging of AV-01

Detailed logging of the first drill hole AV-01 has been completed along with down hole gamma ray geophysical logging. Logging has identified seven individual layers within the Middle Member of the Pochico Formation consisting of weakly laminated quartzite-slate lithologies (Table 2). These layers are separated by strongly laminated slates with minor quartzite interbeds. Drilling terminated at 187.8m depth in massive quartzite units correlated with the Lower Member of the Pochico Formation.

The Company makes no representation regarding the grades of the identified layers. All drill intercepts will be sent to an independent laboratory for accurate analysis, with assay results expected in approximately 3 to 4 weeks.

Drilling update

A second drill rig has arrived on site and is expected to commence drilling on Wednesday 15 October 2025. An additional drill hole (AV-01bis) has commenced on the same drill pad as AV-01 but at a different angle. This drill hole is designed to test the continuity of the geology observed in AV-01.

The second drill rig has moved to a location 1.7km WSW of AV-01 and is expected to commence drilling shortly (SOR-02 in Figure 1). SOR-02 is designed to further test the continuity of the prospective stratigraphy in the southern reaches of the Project.
