Latest Limestone Resources News

Estrella Resources has moved its Timor-Leste strategy into a more consequential phase, with maiden drilling approved at the Laleno Dome copper-gold target and high-grade surface results supporting a porphyry interpretation. Manganese export approvals and a major Werumata limestone resource upgrade add near-term catalysts, although cash covered only 1.27 quarters of reported funding.

Estrella Resources has upgraded confidence in its Werumata limestone project, moving 274Mt into the Indicated category after expanding bulk-density data. The total resource falls to 533Mt from 621Mt, but the company says the change reflects revised density assumptions rather than less mineralised rock.

Estrella Resources has delivered a 27,371-tonne manganese stockpile and a maiden 621-million-tonne limestone resource in Timor-Leste, but the operational progress came alongside a $23.98 million FY2026 loss and a $21.13 million impairment of Western Australian assets. The next test is whether the manganese stockpile can become cash and whether Werumata can move beyond an Inferred resource.

Estrella Resources has expanded its Timor-Leste exploration footprint by 100km2 while securing conditional approval to export a 100-tonne manganese sample to an Indonesian customer. The company is also preparing 3,000 metres of drilling and a possible upgrade to part of its 621Mt Werumata limestone resource.

Cassius Mining has secured $2.025 million through a well-supported placement at a 16.67% discount, aiming to fund its Soalara Limestone Project in Madagascar and ongoing arbitration against Ghana.

Estrella Resources has identified multiple high-conductivity anomalies at its Ira Miri project via a novel UAV geophysical survey, prompting plans for the deepest mineral exploration drilling ever in Timor-Leste starting September 2026.

Estrella Resources has delivered a 27,371-tonne manganese stockpile with nearly 5,000 tonnes grading above 49% Mn at Ira Miri and declared a maiden 621Mt JORC Inferred limestone resource at Werumata, underpinning its emerging Timor-Leste portfolio.

Estrella Resources has launched a cutting-edge UAV-based electromagnetic survey at its Ira Miri manganese project to explore deeper and lateral extensions of high-grade mineralisation, aiming to refine geological models and support mining licence applications.

Estrella Resources has announced a substantial maiden JORC (2012) inferred limestone resource of 621 million tonnes at its Werumata project in Timor-Leste, highlighting multiple product streams and significant upside potential.

Estrella Resources has completed a Category B market appraisal at its Ira Miri manganese project, confirming a 27,371 tonne stockpile including nearly 5,000 tonnes of high-grade manganese. Exploration upside remains significant with open mineralisation and upcoming geophysical surveys.

Estrella Resources has initiated Timor-Leste’s inaugural hard rock mineral extraction at its Ira Miri manganese project, advancing towards full-scale mining and simultaneously progressing a major limestone resource at Werumata.

Estrella Resources has completed its 2025 drilling program at the Werumata Limestone Project in Timor-Leste, reporting broad, high-grade limestone and chalk intersections that pave the way for a maiden JORC resource estimate.
