South Spring Hill Targeted for Up to 1.64Mt at 5.8g/t Gold by Haranga

Exploration Target Defined at South Spring Hill

Haranga Resources Limited (ASX:HAR) has revealed an independent Exploration Target for its South Spring Hill prospect, part of the wholly owned Lincoln Gold Project located in California’s renowned Mother Lode Gold Belt. The target estimates a tonnage range of 1.16 to 1.64 million tonnes grading between 5.4 and 5.8 grams per tonne gold, translating to a potential 202,000 to 308,000 ounces of gold at a 2.0 g/t cut-off grade.

This announcement underscores the prospectivity of South Spring Hill, which historically produced around 94,600 ounces of gold during mining operations dating back to the late 19th century. The historical recovered grade is estimated at approximately 6.6 g/t gold, indicating a high-grade system that modern exploration techniques are now poised to re-evaluate.

Strategic Advantages and Project Infrastructure

The Exploration Target lies within a package of owned and leased mineral claims that benefit from existing underground access and a conditional use permit allowing gold production. Notably, the project includes a mill circuit that was operational as recently as 2022, providing Haranga with a significant infrastructure advantage that could accelerate development timelines.

Chairman Michael Davy highlighted the strategic importance of South Spring Hill within the broader Lincoln Gold Project, noting the potential for multiple remnant orebodies along strike and at depth. The Mother Lode is globally recognised for its extensive gold mineralisation, with occurrences historically identified at depths exceeding 2,000 metres. Haranga’s systematic approach aims to prioritise resource growth opportunities to build scale and quality, supporting a robust development scenario.

Advancing Towards JORC Compliance and Ongoing Drilling

In addition to the Exploration Target, Haranga is targeting the conversion of a 2015 NI 43-101 foreign resource estimate for the Lincoln-Comet deposit; comprising approximately 958,910 tonnes at 9.29 g/t gold for around 286,000 ounces; into a JORC-compliant Mineral Resource Estimate by the end of April 2026. This conversion is critical for aligning the project with Australian reporting standards and enhancing investor confidence.

Drilling and dewatering activities are progressing on schedule, with assay results from underground drill holes expected in April. These results will inform further targeting of mineralisation repetitions at depth, potentially expanding the resource base. Haranga plans additional surface and underground diamond drilling over the next two years, subject to access, to further delineate and upgrade the Exploration Target.

Robust Historical Data and Independent Assessment

The Exploration Target is supported by an independent assessment conducted by Odessa Resources Pty Ltd, which utilised historical drilling and sampling data alongside modern geological modelling. The deposit features two sub-parallel, northeast-dipping lodes separated by barren rock, with significant gold intersections confirmed in both hangingwall and footwall positions.

Haranga has also undertaken rigorous due diligence on assay data quality, employing modern fire assay and screen fire techniques, supplemented by photon assay verification to address the coarse gold component typical of Mother Lode deposits. The company’s commitment to data integrity and thorough geological logging underpins confidence in the Exploration Target’s potential.
