Greenvale review shows Oasis has uranium supernova potential

• Greenvale Energy analysis identifies potential to make more uranium discoveries at its Oasis project
• Multiple datasets suggest potential for structurally controlled uranium mineralisation
• Pending ground magnetics survey and trenching program to define future drill targets at Oasis with further fieldwork being planned to test and develop broader regional targets surrounding the Oasis deposit

Special Report: Greenvale Energy’s initial regional prospectivity analysis has identified the potential to make further discoveries at its Oasis uranium project in Queensland.

The analysis – part of work aimed at identifying priority areas for exploration – identified nine promising uranium anomalies from historical airborne geophysics.

Rock chip sampling carried out during the subsequent ground-truthing of these anomalies revealed similar structural and mineralisation characteristics to that observed at the Oasis deposit with 16 of the 33 samples returning highly anomalous values of up to 187ppm uranium in the intermediate intrusive and 70ppm in granite.

This historical data has been combined with Greenvale Energy’s (ASX:GRV) self-derived exploration results  to identify potential north-south and northeast-southwest trending mineralisation trends in the western and central parts of Greenvale’s EPM27565 tenement.

These orientations are similar to those observed at the high-grade Oasis uranium deposit itself, supporting the potential for additional intrusive-related uranium mineralisation to be discovered elsewhere in the region.

Maiden drilling has confirmed thick, high-grade uranium intercepts with assaying of the second hole delivering 8m at 2125ppm U3O8 from 84m including 5m at 3263ppm from 84m.

“Having just completed our maiden drill program at Oasis, and with initial results confirming the presence of a high-grade deposit, we are very encouraged by the emerging potential for further discoveries surrounding Oasis,” chief executive officer Alex Cheeseman said.

“With multiple datasets suggesting the potential for structurally controlled uranium mineralisation, testing this assumption is rapidly becoming the Company’s main priority at Oasis, with the next phase of field work already underway.

“The emerging opportunity to establish a district-scale uranium project at Oasis is an exciting opportunity for our shareholders.”

Prospectivity analysis

GRV’s prospectivity analysis investigated tenement-wide historical airborne and ground magnetics and radiometrics survey data, collected and initially processed in 2007 and subsequently re-processed in 2024.

It also included rock chip samples collected in July 2025.

The uranium anomalies from the historical radiometrics data (geophysics) and the recent rock chip assays (geochemical) show a strong correlation with the broadly north-south, and northeast-southwest trending structures.

These structures themselves correlate with the mapped positions of the granite/metamorphic contacts, which could be significant as mineralisation at Oasis was originally interpreted to be in a northeast-southwest orientation before preliminary results from the maiden drilling appeared to confirm a more north-south mineralised trend.

This implies that the interaction of both sets of structures could be a major control on mineralisation which, if true, further enhances the exploration model for the surrounding region.

Additionally, high-grade uranium intersected in the 2025 drilling is mostly hosted within a highly sheared, quartz-chlorite-biotite schist and mylonitized granite gneiss.

The highly anomalous rockchip assays were returned from very coarse-grained, biotite-rich granite and diorite intrusives – the latter being an intermediate igneous rock that represents a potential driver for circulating uranium-rich fluids through the system.

Next steps

GRV is currently in the final stages of core processing and sampling from its recently completed drill program with assays to be reported out as they become available.

It will then move to acquire a close-spaced, ground magnetics survey on a 10m by 10m grid to provide high resolution mapping of the structural interplay at Oasis.

Contractors have already mobilised to the project site to commence this work.

Following completion of the ground magnetics survey, the company intends to conduct a trenching and sampling program to confirm the exact alignment of the shear zone hosting the Oasis deposit, which will in turn generate excellent targets for future drill testing.

Trenching is planned to begin in October 2025.
