Raiden Expands Vuzel Gold Potential with New Multi-Kilometre Arsenic Trends

New Arsenic Anomalies Suggest Larger Mineralised System

Raiden Resources Limited (ASX:RDN) has expanded the exploration potential of its Vuzel Gold Project in Bulgaria with the definition of a multi-kilometre arsenic-in-soil trend across the southern and western parts of the licence area. The newly identified arsenic anomalies are significantly more intense than those associated with the gold mineralisation in the previously drilled central zone, suggesting a potentially larger mineralised footprint.

The arsenic trends are spatially linked to interpreted thrust faults and structural features that could represent vertical feeder zones, analogous to the high-grade gold feeder zones intersected in earlier drilling campaigns. While no new gold or silver assay results were reported, the presence of these arsenic anomalies, detected via field portable XRF analysis, provides a compelling early-stage geochemical signature for follow-up exploration.

This development builds on Raiden’s ongoing work at Vuzel, which has seen positive drill results in the central mineralised zone over the past year. The company’s recent soil sampling and geological mapping programs have delineated these new anomalies on a 50m by 50m grid, with over 2,000 samples collected in the southern and western areas. The intensity and scale of the arsenic anomalism, combined with its association with structural contacts, underpin management’s view that Vuzel’s mineralised system could be more extensive than previously understood. This aligns with the project’s epithermal low sulfidation gold style, hosted in Palaeocene-Eocene sedimentary rocks.

Permitting and Metallurgical Advances Underway

Permitting remains a key hurdle for Raiden, particularly regarding drill access to the historically defined silver anomaly within the project. Initial applications for drill pads on municipality-owned land were declined due to existing third-party lease arrangements. Raiden has since reinitiated the permitting process targeting alternative land parcels managed by the Bulgarian Forestry Department, with expectations for approvals in due course. The company also notes the possibility of accessing the originally proposed drill locations if initial drilling results prove positive.

Meanwhile, metallurgical testwork aimed at developing a simple, cost-effective, gravity-focused processing flowsheet is nearing completion, with results anticipated shortly. This work is critical to defining the project’s economic viability and complements the exploration activities by potentially reducing processing complexity and costs.

Strategic Location and Next Steps

Vuzel’s location in the Eastern Rhodope region of Bulgaria places it near the Ada Tepe deposit, mined by Dundee Precious Metals, and within 20 kilometres of the Gorubso-Kardzhali gold processing facility. This proximity to existing infrastructure and other deposits such as Rozino, recently acquired by Türker Mining, could offer synergies if a viable resource is confirmed.

Raiden plans further work throughout 2026, including additional geochemical sampling, mapping, stream sediment sampling, and potentially drill testing the newly defined arsenic and silver targets. The company’s disciplined capital deployment strategy aims to enhance project value while managing permitting and technical risks.

These developments come as Raiden also advances its Crixás Gold Tailings Project in Brazil, where permitting for drill programs over silver anomalies is progressing. The company’s broader exploration portfolio and strong treasury position provide a solid platform for ongoing activities at Vuzel and elsewhere. The recent discovery of multi-kilometre arsenic trends at Vuzel adds a new dimension to the project’s potential, warranting close attention to upcoming assay results and permitting milestones.
