Odyssey Gold Unveils High-Grade Metallurgical Drill Results at Tuckanarra

Context of the Metallurgical Drilling

Odyssey Gold Limited (ASX:ODY) has released assay results from its recent metallurgical drilling program at the Tuckanarra Project, situated in Western Australia's prolific Murchison Region. The program involved two triple-tube diamond drillholes designed to generate representative samples for gravity and leach metallurgical testwork, focusing on shallow oxide mineralisation within the Cable East structure.

The drilling aimed to validate and enhance understanding of gold mineralisation continuity and grade, supporting the existing approved Mining Proposal and feeding into an upcoming scoping study. Notably, the results from these holes have outperformed historic drillholes from the early 1990s, suggesting a potential upgrade in resource quality.

Key Assay Highlights and Geological Insights

The standout intercept was from hole MET002, which returned 22.3 metres at 7.4 grams per tonne (g/t) gold, with a true width estimated at approximately 15 metres starting from 8.7 metres downhole. Additional significant intervals included 3.7 metres at 1.2 g/t and 3.75 metres at 0.9 g/t from MET001 and MET002 respectively. These grades compare favourably to historic holes such as 92TRC336, which reported 30 metres at 3.8 g/t.

Geologically, the mineralisation is associated with pisolite-rich oxide zones and quartz veining within banded iron formations and ultramafic units. The drilling confirmed the presence of nuggety gold mineralisation, which historically may have been underestimated due to partial digestion in earlier assay methods. The use of photon assay technology, which analyses larger sample sizes, has provided a more representative assessment of gold content.

Implications for Mining and Resource Development

The metallurgical samples collected are intended to generate composites that reflect the material types and grades expected in the shallow oxide mining stage. Although MET002’s grade exceeded the target composite for leach testwork, ongoing metallurgical testing will refine processing parameters such as gravity recovery, cyanidation efficiency, and grind optimisation.

Odyssey’s Executive Director, Matt Syme, emphasised the encouraging nature of these results, highlighting the potential for high-grade oxide mineralisation to support near-term mining operations. The company plans to integrate these findings into an updated Mineral Resource Estimate (MRE) and advance a scoping study to assess economic viability.

Next Steps and Exploration Outlook

Further work includes detailed geological interpretation to better define mineralisation controls and continuity. A reverse circulation (RC) drilling program is scheduled to test extensions of the Cable Hanging Wall structure to the south, along with laterite targets to the west and high-grade zones north of the Cable Pit. These efforts aim to upgrade inferred resources to indicated status and potentially expand the resource base.

Overall, the metallurgical drilling results at Tuckanarra reinforce Odyssey Gold’s strategy to develop a robust, shallow oxide gold operation with promising grades and recoveries. The integration of modern assay techniques and comprehensive geological data marks a significant step forward in unlocking the project’s value.
