Muvero Drill Hole Yields 8.46% Cs2O Over 4m, Tyranna Strengthens Cash Position to $3.9M
Tyranna Resources reports significant lithium and caesium assay results from its Namibe Project in Angola, setting the stage for focused 2025 exploration with strategic partner Sinomine Resources.
- High-grade lithium and caesium mineralisation confirmed at Muvero and Loop prospects
- Best caesium intersection: 4.05m at 8.46% Cs2O from Muvero drill hole NDDH010
- 2025 fieldwork to prioritise emerging caesium target with Sinomine partnership
- Strong financial position with $3.941 million cash and no debt at quarter end
- Ongoing evaluation of base metals, gold, and lithium opportunities in Angola
Exploration Highlights from the March Quarter
Tyranna Resources Limited (ASX: TYX) has delivered a robust set of assay results from its late 2024 diamond core drilling campaign at the Namibe Lithium-Caesium Project in Angola. Eleven drill holes across the Muvero, Loop, and Calicatas prospects revealed significant spodumene-hosted lithium mineralisation alongside high-grade caesium pollucite, underscoring the project's multi-element potential.
The standout intersection came from drill hole NDDH010 at the Muvero Prospect, which returned 4.05 metres grading 8.46% Cs2O, the highest caesium grade recorded to date by Tyranna. Lithium results were also encouraging, with the Loop Prospect delivering up to 15.72 metres at 1.58% Li2O from surface, and Muvero showing multiple spodumene intervals exceeding 1.4% Li2O.
Strategic Partnership and 2025 Exploration Focus
Managing Director David Crook highlighted the evolving focus for 2025, noting that fieldwork will increasingly target the emerging caesium zone at Muvero in collaboration with Sinomine Resources (Hainan) Lithium Co., Ltd. Sinomine’s global expertise in caesium markets is expected to add strategic value to Tyranna’s exploration efforts.
“All drilling and surface geochemistry data have been reviewed and prospective areas ranked,” Crook said. “Our partnership with Sinomine will enable a more concentrated approach on the caesium target, while we continue to assess other base metals, gold, and lithium opportunities within Angola.”
Financial Position Supports Ongoing Exploration
At the close of the March quarter, Tyranna reported a healthy cash balance of $3.941 million with no debt, underpinning its exploration activities. Operational expenditure for the quarter was $0.768 million, primarily allocated to exploration and corporate administration. The Muvero project’s exploration is funded under an agreement with Sinomine, reflecting a well-structured financial partnership.
The company’s disciplined cash management and strategic collaborations position it well to advance its portfolio in Angola’s underexplored but mineral-rich terrain.
Context and Outlook
The Namibe Project targets the Giraul pegmatite field, a historically underexplored area with known occurrences of lithium-bearing spodumene and caesium-rich pollucite. Tyranna’s drilling since 2022 has progressively delineated mineralised zones, with the recent results confirming both the scale and grade potential of the pegmatites.
Looking ahead, Tyranna plans to intensify drilling at Muvero to better define the caesium mineralisation and explore its economic viability. Concurrently, the company remains active in evaluating additional mineral prospects in Angola, aiming to capitalise on demand-driven commodities critical to the global energy transition.
Bottom Line?
Tyranna’s latest results and Sinomine partnership set a promising foundation for advancing high-value lithium and caesium resources in Angola.
Questions in the middle?
- How will Sinomine’s involvement influence the pace and scale of Muvero’s development?
- What are the next steps and timelines for resource estimation and potential feasibility studies?
- How might Tyranna’s broader exploration strategy in Angola evolve amid shifting global demand for battery metals?
