4.56 g/t Gold Assay Validates Carlin-Style Potential at Bayan Springs South

Exploration Breakthrough at Bayan Springs

Bayan Mining and Minerals Limited (ASX: BMM) has announced compelling early-stage exploration results from its Bayan Springs Projects in northeastern Nevada, USA. The company’s recent reconnaissance prospecting and geochemical sampling program has yielded high-grade gold assays and significant pathfinder element anomalies, confirming the potential for Carlin-style gold mineralisation within the project area.

At Bayan Springs South, rock chip sampling returned an outstanding gold assay of 4.56 grams per tonne (g/t Au), accompanied by elevated arsenic and antimony concentrations, key geochemical indicators of Carlin-type mineral systems. These findings are particularly encouraging given the spatial association of gold mineralisation with jasperoid alteration zones, a hallmark of Carlin-style deposits.

Geological Parallels to a Major Nevada Gold District

The Bayan Springs South project shares striking geological and structural similarities with the nearby Bald Mountain gold deposit, operated by Kinross Gold Corporation, located just 10 kilometres to the south. Both projects feature mineralisation hosted within Paleozoic carbonate formations, including the Dunderberg Shale and Hamburg Dolomite, and are structurally controlled by thrust faults and high-angle fractures. The presence of jasperoid alteration and decalcification further aligns Bayan Springs with the Carlin Trend’s prolific gold systems.

Executive Director Fadi Diab highlighted the significance of these analogies, stating that the results validate their exploration model and reinforce confidence that Bayan Springs may be part of a broader mineralised corridor. The discovery of diorite float material suggests a potential unexposed intrusive body at depth, which could act as a hydrothermal driver similar to those influencing mineralisation at Bald Mountain.

Anomalous Geochemistry at Bayan Springs North

Complementing the southern findings, soil sampling at Bayan Springs North revealed anomalous concentrations of arsenic (up to 171.5 ppm), mercury, antimony, and thallium, elements commonly associated with Carlin-style gold systems. These anomalies occur near granitic intrusions and rhyolite dykes within the same stratigraphic sequence that hosts the adjacent Maverick Springs mineralisation, underscoring the area’s exploration potential.

The project’s location within the tectonically active Great Basin province, close to the Carlin Trend structural feature, provides a favourable geological setting for sediment-hosted gold and silver deposits. The combination of carbonate-rich sedimentary units, structural complexity, and proximity to known mineralised systems creates a promising environment for further discovery.

Looking Ahead: Systematic Exploration and Drilling

Bayan Mining plans to advance the Bayan Springs Projects with systematic rock chip and soil sampling, detailed geophysical surveys, and ultimately drilling to refine and test the identified targets. The company is also compiling and interpreting extensive historical exploration data to guide its next steps.

While no drilling results have been reported yet, the current data provide a robust foundation for the company’s exploration strategy. Investors and analysts will be watching closely as Bayan Mining moves into this critical phase, with the potential to delineate significant gold resources in a globally recognised mining jurisdiction.
