Tyranna Resources Hit Spodumene-Bearing Pegmatites at Muvero Prospect

Tyranna Resources (ASX:TYX) has provided a comprehensive update on the Muvero Prospect drilling program, a pivotal element of the Namibe Lithium Project, where 17 RC drill-holes (MRC01 to MRC17) have successfully reached a depth of 2,656 metres, uncovering encouraging intersections of spodumene-bearing pegmatites.

Drilling Highlights

The completion of drill-holes MRC01 to MRC17 has marked a significant milestone, with spodumene identified in drill-cuttings from 13 of these holes.

Impressively, over 75% of the drill-holes intersected spodumene-bearing pegmatite, confirming the presence of valuable lithium resources.

The prospect’s unexplored depth also showed potential, with unexposed spodumene-bearing pegmatites confirmed.

Distinctive Intersections

In seven drill-holes, specifically MRC01, MRC02, MRC03, MRC04, MRC05, MRC08, and MRC11, three distinctly recognisable intersections of spodumene-bearing pegmatite were revealed.

The diverse spodumene content emphasises abundant resources and offers nuanced insights into mineralisation, with composition details, including cleavelandite, lepidolite, elbaite, muscovite, and quartz, enhancing Tyranna’s understanding of these geological intersections.

Discussion of Drilling Progress

Spanning 500m East-West and 300m North-South, the Muvero Prospect showcases three major pegmatite outcrops and numerous smaller formations.

The ongoing drilling effort has concentrated on the western section, encompassing 15% of the total prospect area, and has yielded notable success with 40 identified intersections of spodumene-bearing pegmatite, exhibiting depths from surface to approximately 120m.

Understanding the nature of Muvero’s pegmatite is crucial, with spodumene primarily presenting as phenocrystic megacrysts within a coarse-grained matrix.

While RC drilling poses challenges in spodumene identification due to fragmented samples, distinctive intersections, illustrated in Figure 2, facilitate visual confirmation.

However, Tyranna maintains a cautious stance, underscoring that visual estimates must not replace laboratory analysis for precise economic evaluation.

Next Steps

Operational efficiency has been a central focus of the drilling program, with most personnel operating out of Namibe initially.

As facilities have improved, operations are transitioning to the camp, reducing travel time and enhancing safety. Looking ahead, drilling is poised to resume in January 2024, with approximately 6,000m left to be drilled at Muvero, alongside exploration at other prospects.

The initial batch of samples has been dispatched for processing, with assay results anticipated in January 2024. These results will play a crucial role in validating visual estimates and further solidifying the economic potential of the Namibe Lithium Project.

Tyranna Technical Director, Peter Spitalny, expressed enthusiasm about the findings, stating that the extensive spodumene intersections in a mere 15% of the Muvero prospect are promising.

“The fact that more than 75% of the drill-holes have intersected spodumene-bearing pegmatite, but drilling has only occurred in about 15% of the Muvero prospect is exciting. Drilling at Muvero will resume in January 2024, with drilling coverage expanding to ensure that the entire prospect is explored effectively and is likely to continue through to April 2024,” he said.

“Tyranna believes the drilling to be completed in 2024 at Muvero will discover substantial amounts of spodumene bearing pegmatite, and drilling of other prospects will yield positive results that further enhance the value of the Namibe Lithium Project!”
