Exploration Surge at Nuckulla Hill Raises Stakes for Auravelle Investors

Expanding the Exploration Footprint

Auravelle Metals Limited (ASX: AUV) has embarked on a major new phase of exploration at its flagship Nuckulla Hill Project in South Australia. Central to this push is a detailed aerial magnetic survey spanning the entire 40-kilometre strike of the highly prospective Yarlbrinda Shear Zone, a structural corridor known to host significant gold mineralisation in the region.

The survey, covering an impressive 9,400 line kilometres at a fine 25-metre spacing, promises to deliver a far more granular geological picture than previous data, which was spaced at 200 metres. This enhanced resolution is expected to sharpen target identification and refine existing prospects, including the high-priority Sheoak gold prospect where recent drilling returned encouraging results of 28 metres at 3.4 grams per tonne gold.

Integrating Advanced Techniques

Complementing the magnetic survey, Auravelle has completed a down-hole televiewer survey at Sheoak. This technology provides detailed imagery of the drill hole walls, offering insights into the structural controls on mineralisation that are not evident from drill chips alone. Such structural understanding is critical for optimising future drilling programs and improving the chances of discovering economically viable gold deposits.

Meanwhile, preliminary metallurgical testwork using bottle roll leaching methods has commenced on key mineralised intervals at Sheoak. Early-stage recovery data will be vital for assessing the potential ease and efficiency of gold extraction, informing future development strategies.

Drilling and Broader Exploration Plans

In-fill and extensional reverse circulation (RC) drilling at Sheoak is set to begin in the coming weeks. This drilling aims to both fill gaps in the existing mineralisation model and extend the known gold zones along strike and at depth, potentially expanding the resource footprint.

Beyond Sheoak, Auravelle is preparing for discovery-focused air-core drilling at Nuckulla Hill scheduled for mid-Q2, alongside ongoing soil sampling and heritage surveys. The company is also planning maiden sampling at its Skye Gold Project in South Australia and soil sampling at the Crown Gold Project near Kalgoorlie in Western Australia, signalling a broad and aggressive exploration agenda.

Strategic Positioning in a Prospective Region

The Yarlbrinda Shear Zone, which Auravelle is targeting, is a well-regarded gold corridor that hosts Barton Gold’s nearby 1.6 million ounce Tunkillia Gold Project. Auravelle’s focused efforts to delineate and expand gold mineralisation here could position the company as a significant player in this emerging gold province.

Managing Director Andrew Muir emphasised the rapid progress and multi-faceted approach, highlighting the integration of geophysical, structural, metallurgical, and drilling data to build a robust understanding of the mineral system. This comprehensive strategy aims to unlock new discoveries and advance the project towards development.
