Copper Mineralisation Confirmed at Two Turiscai Sites, Assays Due Late 2025

Early Signs of Copper Potential

Tivan Limited (ASX – TVN) has reported promising early fieldwork results from its Turiscai Project in Timor-Leste, with visual confirmation of copper mineralisation at two distinct sites, Mota Sohi and Mota Klere. This initial discovery follows the first week of field activities by Tivan’s local geology team, who conducted geological mapping and collected rock samples across accessible areas of the project.

The Turiscai Project covers seven exploration licenses spanning 344 square kilometres, an area geologically analogous to some of the region’s most significant copper-gold deposits, including Grasberg and Ok Tedi. Strategically located about 40 kilometres south of Dili, the project benefits from existing transport routes, facilitating efficient access to key sites.

Systematic Exploration and Next Steps

Stage 1 exploration has focused on reconnaissance sampling and geological mapping, with 51 locations visited and 20 rock samples collected. Visual observations identified various copper minerals such as bornite, chalcopyrite, azurite, and malachite within weathered phyllitic schist formations. While these visual estimates provide encouraging signs, Tivan cautions that laboratory assays are essential to determine the true economic potential.

Assay results from the initial samples are anticipated between September and December 2025. The timeline reflects necessary approvals from Timor-Leste’s local authorities to export samples for analysis at ALS Geochemistry laboratories in Brisbane. Tivan is collaborating closely with the Instituto de Geociências de Timor-Leste and the Autoridade Nacional dos Minerais Timor-Leste to streamline this process.

Building Local Capacity Ahead of Wet Season

Recognising the importance of local expertise, Tivan plans to expand its field capabilities in Timor-Leste before the onset of the wet season later this year. The company’s country representative, Francisco da Silva Mendonça, will coordinate efforts from the new Dili office alongside the Australian geology team. This approach aims to maximise exploration productivity during favourable seasonal conditions.

Executive Chairman Grant Wilson highlighted the significance of the early findings and the strong partnership with Timor-Leste’s government. He reaffirmed the company’s target to commence preliminary resource drilling in the second quarter of 2026, a critical milestone for advancing the project towards resource definition.

Strategic Implications

Tivan’s Turiscai Project represents a strategic entry into a region with underexplored copper-gold potential but geological settings comparable to world-class deposits. The early visual confirmation of mineralisation, combined with systematic sampling and planned drilling, positions the company well to unlock value. However, investors should note that assay results and subsequent drilling outcomes will be pivotal in validating the project’s commercial prospects.
