Raiden Strikes Gold: Extensive Near-Surface Mineralisation Confirmed at Vuzel Project
Raiden Resources Limited (ASX: RDN) has announced significant results from its Phase 2 drilling programme at the Vuzel Gold Project in Bulgaria, confirming the potential for a major shallow gold system. Every drillhole in the programme has intercepted gold mineralisation, strengthening the company's exploration model and highlighting the project's strategic importance in the company's portfolio.
Promising Drill Results Reveal Extensive Gold System
The latest assay results from Raiden's ongoing 2,000-metre diamond drilling campaign at Vuzel have delivered compelling evidence of a widespread gold system with high-grade components. All eight Phase 2 holes have intercepted near-surface gold mineralisation, with multiple high-grade zones identified.
Standout intercepts include:
- VZ2517: 24.8m @ 1.96g/t Au from surface, including 13.3m @ 3.40g/t Au
- VZ2514: 56.0m @ 1.09g/t Au from surface, including 8.3m @ 4.94g/t Au from 47.7m
- VZ2412: 47.5m @ 0.53g/t Au from 2.5m
- VZ2515: 22.0m @ 0.36g/t Au from surface and 23.2m @ 0.57g/t Au from 71m
The drilling programme focused on a 1.5km section within a larger 4km target area, with assays for additional holes still pending and drilling ongoing.
"I am pleased to report that all assay results received to date from the second phase of the Vuzel drilling campaign have confirmed significant gold mineralisation, extending over a meaningful strike length and width," said Dusko Ljubojevic, Managing Director of Raiden. "These results build on the strong foundation of our maiden drilling programme, which also intersected gold mineralisation in every hole."
Geological Understanding Enhanced
The drilling has provided crucial insights into the controlling structures that acted as conduits for gold emplacement. According to the company, gold mineralisation at Vuzel is associated with zones of oxidised, silicified conglomerates and sandstones with quartz-mica-pyrite and silica-clay-pyrite alteration assemblages.
The current interpretation suggests that mineralisation preferentially developed along sub-horizontal conglomerate units near intersections with steep-dipping faults. These faults likely served as feeder structures for mineralising hydrothermal fluids, which then flowed into permeable conglomerate units where gold precipitation occurred.
The near-surface, shallow-dipping nature of the mineralisation is particularly advantageous, as it will allow for rapid, cost-effective follow-up drilling to explore the full extent of the system. Similar promising gold-silver veining has been observed in other mining projects across the region.

Understanding Epithermal Gold Deposits
Epithermal gold deposits like Vuzel form relatively near the Earth's surface (typically within 1-2km depth) in volcanic terrains. They develop when heated groundwater circulates through rock fractures, dissolving metals and then precipitating them as conditions change.
Low-sulphidation epithermal deposits—the type identified at Vuzel—typically form from near-neutral pH fluids and are characterised by quartz veins, often with adularia and calcite. These deposits can host significant gold mineralisation, sometimes with high grades, and frequently occur in extensional tectonic settings.
The geological setting at Vuzel shares similarities with the epithermal low-sulphidation Ada Tepe deposit currently being mined by Dundee Precious Metals just 30km southeast, highlighting the regional prospectivity. Several companies have recently launched drilling campaigns in similar geological environments worldwide.
Strategic Position in an Emerging Gold District
The Vuzel project is strategically located in southeastern Bulgaria within the prolific West Tethyan metallogenic belt. Importantly, it sits less than 20km from Gorubso-Kardzhali A.D.'s gold processing facility, potentially offering future development synergies.
Recent regional activity underscores the area's economic potential. Türker Mining, a subsidiary of Turkish conglomerate Türkerler Holding, recently acquired Velocity Minerals' Bulgarian assets, including the Rozino deposit (573Koz @ 0.8g/t Au), for US$59 million.
This transaction demonstrates the significant value potential in the region and provides a benchmark for evaluating similar assets like Vuzel. Other companies, such as Austin Metals, have also begun drilling in proximity to major producers, indicating growing interest in the region.
Next Steps for Vuzel Exploration
Raiden will complete the initial programme aimed at defining the extent of mineralisation within the central 1.5km zone. Results will guide future drilling, with particular focus on better targeting the high-grade feeder structures within the sedimentary package.
The company also plans to expand exploration across the entire 3-4km prospective strike length defined by anomalous gold values. This systematic approach could rapidly advance understanding of the deposit's scale and economic potential.
"The results continue to validate our exploration model and reinforce our geological understanding of the Vuzel Gold Project, strengthening our view that it represents a strategically significant asset within the Company's portfolio," notes Ljubojevic.
Why Investors Should Follow Raiden Resources
Raiden's gold discovery by Raiden Resources Ltd at the Vuzel project demonstrates several compelling attributes that merit investor attention:
