Highlights

  • Renascor advances drilling and sampling programs across Bulloo Creek, Tumby Bay and Marree prospects.
  • Approvals secured for 3,000m drilling at Bulloo Creek targeting copper–cobalt–gold zones.
  • Tumby Bay reassays and hyperspectral data outline additional REE targets for follow-up work.

Renascor Resources (ASX:RNU) reported that it has secured the final regulatory clearances required to start a reverse circulation (RC) drill program of up to 3,000m at its 100%-owned Bulloo Creek prospect in South Australia’s Curnamona Province. Drilling is scheduled to begin this month and is expected to take approximately two weeks.

The company has mapped multiple near-surface copper–cobalt–gold targets along a magnetic trend extending around 4km. Within the “Eastern Anomaly,” three shallow magnetic bodies have been modelled from depths as low as 56m and span about 500m in strike. These bodies correlate with surface cobalt results of up to 55ppm and with notable cobalt intercepts recorded during Renascor’s earlier drilling activities.

A separate magnetic body defined in the “Western Anomaly” zone was not intersected in prior drilling, though copper grades in past holes increased toward this feature. Renascor considers the area prospective for mineralisation similar to occurrences recorded nearby.

Tumby Bay: Reassays Confirm Magnetic REE-Rich Zones

At the Tumby Bay rare earth elements (REE) prospect on South Australia’s Eyre Peninsula, Renascor completed a comprehensive reassay of historical drillholes. Earlier work identified elevated REE within a shallow brecciated talcose clay horizon. The latest assays confirmed high proportions of magnetic rare earth oxides (MREO), including dysprosium and terbium.

Drillhole DD07TB003 returned an average of ~2,218ppm total rare earth oxides (TREO) and ~33% MREO (~826ppm) from surface to 51.6m end-of-hole. Additional significant intervals included 1.55m at 11,796ppm TREO and 36m at 3,106ppm TREO. Reassays from holes DD07TB001 and DD07TB002 also indicated REE presence, with DD07TB002 encountering mineralisation from surface before being abandoned at 9m.

Soil sampling around DD07TB003 outlined a ~1km REE anomaly graded between 300–865ppm, alongside a secondary NE–SW trend extending roughly 2.5km. Hyperspectral satellite analysis further identified alteration and mineral signatures aligned with potential clay-hosted REE enrichment.

Planned work includes additional infill soil sampling, target prioritisation, mineralogical characterisation via XRD/SEM, and bench-scale metallurgical testing of representative material.

Marree: Early-Stage Work and Access Processes Continue

At the Marree project in the Adelaide Rift Complex, Renascor is progressing community engagement and land-access negotiations across its exploration licences. The project includes the Mulgaria uranium and copper prospect, defined by a 2km by 1km radiometric anomaly showing responses up to 10ppm uranium, around five times background levels and among the strongest in the eastern Gawler Craton.

Renascor states that Mulgaria presents near-surface and basement-related uranium and copper target potential. On-ground exploration activities will commence following completion of Native Title and heritage clearances.

Battery Anode Material Project: Development Work Ongoing

Alongside exploration, Renascor is continuing development activities for its Battery Anode Material project. Current work includes engineering, infrastructure planning, water-management optimisation and accommodation-camp preparation for the upstream mining and processing site.
