Yandal’s Exploration Surge Hinges on Uncertain Arrakis Mineralisation Width

Exploration Breakthrough at Arrakis

Yandal Resources Limited (ASX, YRL) has delivered a compelling update for the September 2025 quarter, confirming its second major gold discovery within a year at the Arrakis prospect, located in the Caladan target area of the Ironstone Well-Barwidgee Gold Project in Western Australia’s prolific Yandal Greenstone Belt. Reverse circulation (RC) drilling has returned significant fresh rock gold intercepts beneath a 2.2-kilometre mineralised trend initially defined by air-core drilling, including standout results such as 54 metres at 1.2 grams per tonne (g/t) gold from 108 metres depth, featuring higher-grade zones up to 4.7 g/t over 8 metres.

This discovery underscores the potential scale of the mineralised system and validates Yandal’s exploration methodology, which combines detailed gravity surveys with targeted drilling. The Arrakis trend’s continuity into fresh rock suggests a robust geological setting that could support a substantial resource in the future.

Advancing Exploration and Strategic Asset Management

Alongside the Arrakis breakthrough, Yandal has progressed exploration at the New England Granite target, where a 5,000-metre air-core drilling program is testing newly identified structural targets. Early results and geological interpretations indicate that mineralisation is associated with deformation zones both near and away from the intrusive margins, guiding refined targeting strategies for 2026.

At the Mt McClure Gold Project, a comprehensive ground gravity survey was completed to enhance structural and stratigraphic understanding, setting the stage for future drilling campaigns. Meanwhile, the Flushing Meadows deposit, hosting a 268,000-ounce gold resource, remains a focus for upcoming exploration aimed at expanding mineralisation along strike and at depth.

On the corporate front, Yandal executed a binding agreement to divest its Gordons Gold Project to Horizon Minerals Limited for A$2.81 million in cash and shares, enabling the company to concentrate resources on its core projects. The sale is expected to complete shortly, providing additional financial flexibility.

Capital Raising and Financial Position

Post-quarter, Yandal successfully completed a placement raising approximately A$13.5 million before costs, issuing over 46 million new shares at 29 cents each. This capital injection is earmarked to accelerate exploration activities at Arrakis, New England Granite, and Flushing Meadows, underpinning an aggressive drilling and development program through 2026.

At quarter-end, the company held approximately A$2.26 million in cash and cash equivalents, supported by in-the-money unlisted options that could provide a further A$2.6 million if exercised by mid-November 2025. Operating expenditure for the quarter included around A$2.12 million on exploration, reflecting the company’s commitment to advancing its project pipeline.

Looking Ahead

Yandal’s near-term plans include ongoing diamond drilling at Arrakis to extend and better define the mineralised system, further air-core drilling across the Caladan target area, and follow-up RC drilling on 200-metre spaced lines to delineate the extent of mineralisation. The New England Granite air-core program is nearing completion, with results anticipated soon to guide 2026 drilling. The company also aims to develop a targeted exploration strategy for Flushing Meadows focusing on fresh rock mineralisation and parallel targets.

These activities position Yandal Resources to potentially unlock significant value from its portfolio in one of Australia’s most prolific gold belts, with the Arrakis discovery providing a promising foundation for growth.
