Kingman Drilling Yields Up to 71.9 g/t Gold and 169.9 g/t Silver Assays

Strong Assay Results Reinforce Kingman’s Potential

Riedel Resources Limited (ASX:RIE) has announced a series of high-grade gold and silver assay results from its recent diamond drilling program at the Tintic deposit, part of the Kingman Gold Project in Mohave County, Arizona. Notably, drill hole DD25TT012 returned an exceptional 0.61 metres at 71.9 grams per tonne (g/t) gold and 92.5 g/t silver, while DD25TT019 intercepted 4.42 metres at 11.2 g/t gold and 169.9 g/t silver. These shallow intercepts, occurring between 10 and 30 metres depth, suggest the potential for cost-effective extraction and provide a strong foundation for the next phase of exploration.

Confirming and Extending the Geological Model

The drilling results have not only delivered high-grade mineralisation but also confirmed the existing geological model of the Tintic deposit. Structural measurements and assay correlations verify that the gold-silver lodes occur as predicted, with localised faults and shear zones identified that will help refine the understanding of vein offsets. The presence of elevated silver alongside gold supports an electrum and silver-bearing sulphide style mineralisation, consistent across multiple intercepts. This continuity, despite expected short-scale grade variability typical of nuggety gold systems, reinforces the deposit’s robust tenor.

Exploration Beyond Tintic: Silver Fox and Regional Upside

Beyond Tintic, drilling at the Silver Fox prospect intersected low-level gold-silver mineralisation along a significant north-south structural corridor, spatially linked to a tonalite porphyry dyke. This intrusive phase is analogous to known porphyry copper-molybdenum systems nearby, hinting at a concealed magmatic system beneath the project area. The Kingman Project remains largely underexplored, with a significant portion untested by soil geochemistry or drilling, presenting compelling opportunities for new discoveries, including potential copper porphyry targets.

Next Steps: Metallurgical Testing and Expanded Exploration

Riedel is advancing metallurgical testwork using high-quality core samples to assess heap-leach amenability and recovery rates, particularly focusing on oxide and transitional zones rich in iron-oxide alteration. Concurrently, the company is designing a detailed soil geochemical program and trenching initiatives to expose bedrock and refine drill targeting across the southern project area. Importantly, Riedel is preparing an Exploration Plan of Operations for submission to the U.S. Bureau of Land Management, which will facilitate expanded on-ground activities while managing environmental disturbance limits.

Strategic Positioning in a Major Mineral Belt

Situated at the convergence of the Southwest USA Copper Porphyry Belt and the Walker Lane Nevada Gold Belt, the Kingman Gold Project benefits from a highly prospective geological setting. Historical mining and recent exploration underscore the district’s potential, and Riedel’s systematic approach combining drilling, geochemistry, and structural modelling positions it well to unlock further value. The company’s chairman, Scot Cuomo, emphasised the opportunity to explore regional extensions and additional targets, signalling a confident outlook for the project’s development trajectory.
