Estrella Resources (ASX:ESR) Announces Significant Manganese Discovery
Estrella Resources Limited (ASX: ESR) has announced the intersection of 6.45 meters of massive manganese oxides in its maiden drill hole, EMDD001, at the Ira Miri Prospect in Lautém, Timor-Leste. This milestone represents the first modern metallic minerals exploration in the country’s history.
Discovery Details
Drill hole EMDD001 encountered mineralisation 1.35 meters down hole, ending in manganese oxides at a depth of 7.8 meters. Positioned three meters from the main Ira Miri discovery outcrop, initial rock-chip laboratory assays in February 2025 returned manganese grades between 40.0% and 58.6%. Additionally, trenching eight meters to the southeast revealed non-outcropping massive manganese oxides just 0.7 meters below the surface, extending to a depth of three meters.
Drill Program
The exploration program includes an initial 3,000 meters of diamond drilling and 10,000 meters of reverse circulation (RC) drilling. A secondary round of 10,000 meters of RC drilling is planned following a geological review. The successful drilling was achieved within six months from the initial discovery in November 2024, with full mobilisation by CoreSearch from Darwin.
Executive Comments
Estrella Managing Director Chris Daws stated, “What a fantastic discovery for Estrella and our loyal shareholders! While these are early results from just our first hole and trench in Timor-Leste, the findings are significant. Not only does it provide confirmation that manganese mineralisation extends sub surface, it also provides further confidence in the accuracy of our developing exploration model which seeks to identify rich manganese deposits.”
Murak Rai Timor Managing Director Jose Goncalves added, “We are very pleased that the initial drill hole at Ira Miri Prospect has encountered massive manganese oxides as hoped. We look forward to resuming the drilling to uncover more potential across the targeted area.”
