Extensive Auger Drilling Defines Kilometre-Scale Gold-in-Soil Anomalies

Golden Dragon Mining's recent 827-hole auger drilling campaign across the Coodardy/Behring Bore region successfully delineated two large, coherent gold-in-soil anomalies extending over 3 kilometres northeast. This discovery marks a significant advancement for the Cue Gold Project within Western Australia's Murchison Goldfields. The program aimed to detect regional mineralisation trends within this underexplored zone, with results demonstrating the effectiveness of auger drilling in mapping broad surface geochemical signatures.

The anomalies exhibit strong, well-defined gold responses, with peak values reaching 720 parts per billion. The company highlights that the consistency and strength of these gold signals provide a solid basis for targeted follow-up exploration. These results extend beyond previous drilling boundaries, indicating a potentially larger mineralised system than earlier understood.

Anomalies Connect Multiple Prospects into a Unified Northeast-Trending Corridor

A notable outcome of the auger program is the spatial alignment of gold anomalies with several established prospects, linking Curtis Find, Behring Bore, Coodardy, and Piston along a consistent northeast trend. This expanded geochemical corridor suggests these formerly separate targets may be components of a larger, continuous mineralised system rather than isolated deposits.

Golden Dragon interprets this northeast orientation as indicative of structurally controlled mineralisation related to a fault or shear zone traversing multiple prospects. The elongate shape of the combined geochemical anomaly forms a closed, well-defined high rather than scattered anomalous points. This linkage significantly enhances exploration potential and provides a structured framework to prioritise drilling and testing across the Coodardy/Behring Bore area.

Pathfinder Geochemistry Aligns with Orogenic Gold System Signatures

The gold anomalies are strongly associated with key orogenic gold pathfinder elements, notably arsenic and antimony. Golden Dragon notes this geochemical signature is highly indicative of structurally controlled mineralisation typical of orogenic gold systems. The combined Au–As–Sb anomaly defines a coherent northeast-trending corridor oriented approximately 626 azimuth, reflecting a fault or shear-related mineralised system characteristic of orogenic deposits.

Geochemical contouring reveals a closed, elongate high rather than isolated points, supporting the interpretation of a continuous mineralised trend. The company emphasizes that this systematic auger sampling has established a strong exploration vector linking known prospects and highlights substantial discovery potential along this emerging trend. The pathfinder geochemistry validates the gold signals, increasing confidence that anomalies represent true mineralisation rather than background enrichment. This signature aligns with well-documented traits of productive orogenic gold systems in similar geological settings.

Recent High-Grade Drilling at Coodardy Reinforces Expanding Gold System

Alongside the auger program, Golden Dragon continues slimline reverse circulation drilling at Behring Bore and Coodardy, targeting extensions of recently discovered high-grade mineralisation. At Coodardy, drilling returned 12 metres at 6.5 grams per tonne gold from 44 metres, including a 4-metre interval grading 17.6 grams per tonne gold. These results complement earlier high-grade intercepts such as 8 metres at 10.82 grams per tonne gold from 25 metres, with a notable 4-metre segment at 21.37 grams per tonne gold.

The consistent high-grade mineralisation across multiple holes at Coodardy confirms the quality of the gold system. Combined with the auger-defined anomalies, these drilling outcomes support the interpretation of a substantial, coherent gold-bearing system across the Coodardy/Behring Bore corridor. The company aims to extend the known high-grade zones, indicating the system remains open at depth and along strike, offering multiple exploration vectors.

Northeast-Trending Geochemical Axis Suggests Structurally Controlled Mineralisation

The geometry of the anomalies offers insights into the mineralisation style. The Au–As–Sb anomaly forms a coherent northeast-trending geochemical axis near 626 azimuth, creating an elongate high. Golden Dragon interprets this linear geometry as evidence of structurally controlled mineralisation linked to a fault or shear zone. The alignment of multiple prospects along this trend suggests a major controlling structure over a broad area.

The elongate anomaly, rather than scattered points, indicates a continuous mineralised trend through the Coodardy/Behring Bore area. This geometry aligns with classic orogenic gold pathfinder signatures typical of deposits formed in compressional tectonic settings where mineralisation focuses along crustal-scale structures. Recognising this structural control provides a strong framework for discovering additional mineralised zones within and beyond the current anomaly.

Advancing Heritage Surveys and Drilling Contractor Engagement for Targeted Exploration

Following the positive auger results, Golden Dragon is progressing heritage surveys and engaging drilling contractors to prepare for targeted drilling of high-priority zones. The extensive and continuous gold anomalies highlight a significant surface gold system warranting immediate follow-up. The newly defined northeast-trending corridor is a priority target for the next exploration phase, aiming to systematically test mineralisation potential along this geochemical trend.

These preparatory steps reflect the company’s commitment to transition from reconnaissance to focused mineral exploration aimed at resource definition along the corridor. Heritage surveys and contractor engagement are standard prerequisites for Australian drilling programs, underscoring Golden Dragon’s intent to rapidly advance this high-priority target. Concentrating drilling on priority areas within the Coodardy/Behring Bore corridor demonstrates a disciplined resource allocation strategy, focusing on zones with the highest likelihood of discovery based on combined geochemical, geological, and drilling data.

Established Exploration Framework Enables Systematic Corridor Testing

The auger program has established a robust exploration framework for the systematic evaluation of the Coodardy/Behring Bore corridor. The kilometre-scale geochemical anomaly connecting multiple prospects provides a coherent geological model to guide follow-up drilling and exploration. The interpreted structurally controlled northeast-trending mineralised system offers a clear vector for identifying and testing additional mineralisation within and beyond the current anomaly.

Golden Dragon’s strategy builds on recent drilling successes at Behring Bore and Coodardy, where high-grade gold has been intersected. The company continues slimline RC drilling at these sites while planning to test the broader corridor defined by the auger program. This integrated approach enables simultaneous definition of known mineralisation and systematic exploration of the wider target area. Combining surface geochemistry, structural interpretation, and targeted drilling creates an efficient staged framework to assess whether the anomalies represent a single large system or multiple discrete deposits.

Cue Gold Project Situated in Proven Murchison Goldfields District

The Cue Gold Project is located within Western Australia’s Murchison Goldfields, a well-established gold-producing region with a rich history of mining and discovery. The district is known for hosting significant orogenic gold mineralisation similar to that interpreted at Coodardy/Behring Bore. Golden Dragon’s project location in this proven mining area supports the geological interpretation and affirms that the identified anomalies align with known regional gold systems.

Operating in the Murchison Goldfields offers exploration advantages including established infrastructure, local expertise, and detailed geological knowledge. The district’s track record of economically significant gold deposits validates the commercial potential of discoveries made there. Golden Dragon’s focus on the Coodardy/Behring Bore area within its Cue Gold Project represents a targeted effort to explore highly prospective ground in a proven gold province. The discovery of kilometre-scale gold anomalies and high-grade drill results in this context indicates a genuinely promising target with potential for further discovery and development.

Strong Geochemical Anomaly Validates Mineral System Confidence

The strength and coherence of the geochemical anomalies provide key validation of Golden Dragon’s interpretation of the mineralised system’s nature and extent. The peak gold value of 720 parts per billion recorded during the auger program is robust and encouraging, offering a reliable geochemical target for follow-up exploration. The well-defined, continuous nature of the anomaly strengthens confidence that a genuine mineralised system exists beneath the surface.

The strong correlation of gold with pathfinder elements arsenic and antimony further substantiates the geological model. These elements are characteristic of orogenic gold systems, reinforcing that the anomalies represent true gold mineralisation rather than residual or background enrichment. The combination of a strong gold signal, coherent anomaly geometry, confirmed high-grade drill intercepts, and characteristic pathfinder geochemistry presents a compelling case for a significant gold system at Coodardy/Behring Bore. Collectively, these factors provide Golden Dragon with heightened geological confidence to advance systematic exploration efforts.
