Osmond Resources Delivers 60Mt Critical Minerals Resource at Orión

Osmond Resources (ASX: OSM) has delivered its maiden Mineral Resource Estimate for the Orión EU Critical Minerals Project — 60.0 Mt at 9.39% TiO₂ across a footprint covering just 3.4% of the 232 km² project area, with drilling resuming in October 2026 and an updated MRE targeted for Q1 CY27.
By William Hadrian -
  • Osmond Resources' maiden Orión MRE totals 60.0 Mt at 9.39% TiO₂, 3.06% ZrO₂ and 6,274 ppm TREO across both seams, with the higher-grade Main Seam alone delivering 49.7 Mt at 10.29% TiO₂ and a 17.9% VHM grade.
  • The current MRE footprint covers just 7.9 km² — only 3.4% of the 232 km² project area — meaning the vast majority of the host formation remains untested and unresourced.
  • Preliminary SysCAD flowsheet modelling indicates three-stream concentrate outputs including a monazite-rich concentrate at 22.6% TREO with 63.6% net recovery and a zircon concentrate at 64.1% ZrO₂ with 60.4% net recovery, though these are not demonstrated plant recoveries.
  • Drilling is set to resume in October 2026, with an updated MRE targeted for Q1 CY27, subject to drilling results, laboratory turnaround and funding.
  • Orión's EU location and alignment with the Critical Raw Materials Act framework positions it as a potential domestic European source of titanium, zirconium, hafnium and rare earth concentrates — commodities currently dominated by non-EU supply chains.

OSM delivers maiden mineral resource as Orión’s scale potential comes into focus

Osmond Resources (ASX: OSM) has delivered its maiden Mineral Resource Estimate (MRE) for the Orión EU Critical Minerals Project, located in Jaén Province, Andalucía, southern Spain. The combined estimate across both seams totals 60.0 Mt at 9.39% TiO₂, 3.06% ZrO₂, 624 ppm HfO₂ and 6,274 ppm Total Rare Earth Oxides (TREO), including 1,801 ppm Magnetic Rare Earth Oxides (MREO).

Critically, that MRE footprint covers just 7.9 km², representing only 3.4% of the broader 232 km² Project area, positioning this as an opening statement on scale rather than the full picture. OSM’s stated ambition is to become the EU’s first producer of monazite (rare earths), zircon (zirconium/hafnium) and titanium minerals.

Main Seam MRE headline results

A 49.7 Mt resource with high-grade credentials

The Main Seam is the sole basis of the current Scoping Study, and it carries the stronger numbers. At a 4.0% TiO₂ cut-off, the Main Seam MRE totals 49.7 Mt at 10.29% TiO₂, 3.42% ZrO₂, 690 ppm HfO₂ and 7,139 ppm TREO (including 2,053 ppm MREO). The highest-confidence material, Measured plus Indicated, totals 13.8 Mt at 11.05% TiO₂.

In-situ contained metal estimates for the Main Seam stand at approximately 5.12 Mt TiO₂, 1.70 Mt ZrO₂, 34.3 kt HfO₂ and 355 kt TREO (including 102 kt MREO). Note that these contained quantities are arithmetic products of in-situ tonnage and grade and do not incorporate mining recovery, dilution, metallurgical recovery, product specification, payability or marketability; they must not be interpreted as recoverable or saleable product quantities.

The Valuable Heavy Mineral (VHM) grade across the total Main Seam sits at 17.9%, comprising 8.6% rutile, 3.3% ilmenite, 5.1% zircon and 1.0% monazite, with an estimated combined contained VHM of 8.9 Mt (subject to the same recoverability qualifications noted above).

What is a mineral resource estimate, and why does this one matter?

Understanding JORC resource classifications

A Mineral Resource Estimate (MRE) is a JORC-compliant estimate of mineralisation that is potentially economic but has not yet been converted to an Ore Reserve. Mineral Resources are not Ore Reserves and do not demonstrate economic viability. The JORC Code classifies resources into three confidence categories:

  • Measured: Detailed drilling confirms geometry and grade with high confidence — the most reliable category
  • Indicated: Sufficient data to assume continuity; forms the basis of Scoping Studies
  • Inferred: Geological continuity is inferred but supported by less drilling data — primarily represents growth upside

Why grade and scale both matter in critical minerals

In heavy mineral sand-style deposits, VHM grade is the key economic driver. Higher VHM means more recoverable product per tonne of material processed, which directly influences operating economics. Orión’s 17.9% VHM grade for the Main Seam, spanning a basket of titanium, zirconium, hafnium and rare earth elements, connects directly to European demand themes around supply chain independence and the EU Critical Raw Materials Act framework.

The Upper Seam adds further scale optionality. Reporting 10.2 Mt at 5.01% TiO₂, it is considered to have reasonable prospects for eventual economic extraction (RPEEE) under an alternative or future development scenario but is not included in the current Scoping Study. The current development concept is focused exclusively on the Main Seam.

Preliminary testwork signals a viable processing path

SysCAD flowsheet modelling has informed a potential three-stream concentrate output from the Main Seam. The modelled outcomes are:

  • Zircon concentrate: 64.1% ZrO₂ at 60.4% net recovery
  • Mixed titanium-mineral concentrate: 71.3% TiO₂ at 36.1% net recovery
  • Monazite-rich concentrate: 22.6% TREO at 63.6% net recovery

These figures include extrapolated cleaning stages and are not demonstrated overall plant recoveries or final saleable product specifications. The announcement explicitly states that representative variability and larger-scale testwork are required to confirm the flowsheet and product performance. PFS-level metallurgical testwork is currently underway, but results were not available at the announcement date.

What comes next: drilling restarts and the path to an updated MRE

Drilling is expected to resume in October 2026, targeting extensions to both the Main and Upper Seams and providing additional data to support potential future resource-category upgrades. Subject to drilling results, laboratory turnaround and funding, the Company is targeting an updated MRE in Q1 CY27. The announcement notes there is no certainty that additional drilling will increase the Mineral Resource or convert Inferred Resources to higher-confidence categories.

The structural framework for those extensions was established earlier in 2026, when Phase 1 assays confirmed a 10km mineralised corridor across the Orión project area, providing the geological targeting basis for the current MRE and the expansion program now underway.

That context matters for scale. The current MRE covers only 3.4% of the 232 km² Project area, leaving the majority of the host formation untested. Key catalysts in the near-term pipeline include:

  • Drilling recommences October 2026
  • Updated MRE targeted Q1 CY27 (subject to drilling results, lab turnaround and funding)
  • Scoping Study progressing, based exclusively on the Main Seam
  • PFS-level metallurgical testwork underway
  • Three additional Investigation Permit applications pending (Metioque, Menodice, Menipe)

No production target, forecast financial information or Ore Reserve is reported in this announcement. Orión’s location within the EU, and its proximity to established infrastructure and European consumers, position it as a potential future source of critical mineral concentrates, subject to completion of studies, permitting, financing and development.

Frequently Asked Questions

What is the Osmond Resources Orión maiden mineral resource estimate?

The Orión maiden MRE totals 60.0 Mt at 9.39% TiO₂, 3.06% ZrO₂, 624 ppm HfO₂ and 6,274 ppm TREO across two seams in Jaén Province, Andalucía, Spain, covering 7.9 km² of the 232 km² project area.

What does VHM grade mean and why does it matter for Orión?

VHM stands for Valuable Heavy Mineral grade — the percentage of economically useful minerals in each tonne of material processed. Orión's Main Seam carries a 17.9% VHM grade comprising rutile, ilmenite, zircon and monazite, which is the primary driver of operating economics in heavy mineral sand-style deposits.

When will Osmond Resources update the Orión mineral resource estimate?

OSM is targeting an updated MRE in Q1 CY27, following drilling expected to resume in October 2026, subject to drilling results, laboratory turnaround and funding availability.

Why is Orión's location in Spain significant for critical minerals investors?

Orión is located within the EU at a time when the EU Critical Raw Materials Act is driving demand for domestic sources of titanium, zirconium, hafnium and rare earths — commodities currently sourced predominantly from outside Europe. An EU-based project has potential permitting, logistics and offtake advantages over non-EU alternatives.

What are the next catalysts for Osmond Resources ASX: OSM?

Key near-term catalysts include drilling recommencing in October 2026, PFS-level metallurgical testwork results, progress on the Scoping Study (based on the Main Seam), an updated MRE targeted for Q1 CY27, and three additional Investigation Permit applications pending in Spain.
