Osmond Resources has expanded the high-grade heavy mineral zone at its Orión EU Critical Minerals Project in Spain, with drill hole SOR-08 intersecting key quartzite layers 1.25km from prior discoveries. This development supports the maiden Mineral Resource Estimate and keeps the company on track for a Q3 2026 Scoping Study.
- Drill hole SOR-08 intersects prospective Pochico Formation quartzite
- High-grade target zone extended 1.25km ESE from discovery holes
- 3.4m quartzite bed at 209m depth identified
- Assay results expected mid-July 2026
- Maiden Mineral Resource Estimate and Scoping Study on schedule
Step-Out Drill Hole Expands High-Grade Zone
Osmond Resources Limited (ASX:OSM) has confirmed that drill hole SOR-08, a step-out hole at the Orión EU Critical Minerals Project in southern Spain, has intersected the heavy mineral prospective quartzite units of the Pochico Formation. Located roughly 1.25 kilometres east-southeast of the initial discovery drill holes AV-01 and AV-01bis, SOR-08 has identified five marker quartzite layers, including a significant 3.4-metre thick bed at 209 metres downhole.
This intersection notably expands the known extent of the high-grade heavy mineral zone into what Osmond terms the Southern Block, suggesting a broader distribution than previously mapped within the Avellanar Block. The company expects this new data to materially contribute to the maiden Mineral Resource Estimate (MRE) currently underway, providing a stronger foundation for the upcoming Scoping Study targeted for completion in the third quarter of 2026.
Implications for Resource Modelling and Project Development
Managing Director Anthony Hall highlighted the importance of SOR-08 in validating the continuity of the high-grade zone beyond the initial discovery area. He noted that the drill hole supports the earlier SOR-02 results, which indicated promising grades over a wider area. While assay results for SOR-08 are pending, expected by mid-July 2026, the geological logging and gamma ray data provide encouraging radiometric signals consistent with heavy mineral enrichment.
Osmond’s geological team, alongside independent consultants based in Spain, is advancing the resource modelling with a focus initially on the Avellanar Block. The addition of the Southern Block through SOR-08’s results opens a new domain for resource targeting, potentially increasing the project’s scale and economic viability.
Project Context and Strategic Positioning
The Orión project, covering 232 square kilometres in Jaén Province, Andalucía, is a siliciclastic system rich in critical minerals including rare earth-bearing monazite, titanium minerals (rutile and ilmenite), zirconium, and hafnium. Previous drilling and bulk sampling have revealed heavy mineral concentrations up to 40% in some zones, with AV-01bis delivering exceptionally high-grade intersections such as 19.1% TiO2 and 1.29% total rare earth oxides (TREO).
Osmond is positioning Orión to become the European Union’s first producer of these critical minerals, aligning with increasing EU regulatory support for domestic sourcing of strategic materials. The company’s ongoing drilling program includes SOR-07, currently at 182 metres depth, aiming to further delineate mineralisation and support the Scoping Study.
Technical Rigor and Next Steps
The drilling program employs HQ-size diamond drilling with rigorous sampling and logging protocols, including downhole gamma ray logging and scintillometer readings to identify heavy mineral layers. Samples are sent to certified laboratories in Spain for comprehensive assay and mineralogical analysis, with quality control measures ensuring data reliability.
Following receipt of assay results expected by mid-July, Osmond will integrate the new data into the Mineral Resource Estimate and advance the Scoping Study. These milestones will be critical in assessing the project’s commercial potential and guiding subsequent development decisions.
Bottom Line?
Pending assay results will clarify the scale of Osmond’s expanded high-grade zone, a pivotal factor for the Orión project's upcoming resource estimate and economic assessment.
Questions in the middle?
- How will SOR-08’s assay results influence the final maiden Mineral Resource Estimate?
- What exploration plans will Osmond pursue in the newly identified Southern Block?
- How might EU regulatory support impact the project’s development timeline and financing?
