Estrella turns Timor-Leste exploration into stockpile and resource milestones

Timor-Leste milestones meet a sharply higher loss

Estrella Resources Limited (ASX:ESR) has spent FY2026 turning its Timor-Leste portfolio from an exploration story into a potential commercialisation story. The company completed a surveyed 27,371-tonne manganese stockpile at Ira Miri and declared a maiden 621-million-tonne JORC (2012) Inferred Mineral Resource at the Werumata Limestone Project. The financial result was far less flattering: the group recorded a $23.98 million net loss, compared with a $2.08 million loss a year earlier.

The largest contributor was a $21.13 million impairment of exploration and evaluation assets. Estrella said its Carr Boyd and Spargoville Western Australian projects were fully impaired during the year, citing the collapse in nickel prices, volatility in market conditions and its strategic focus on Timor-Leste. After the write-down, exploration and evaluation assets stood at $9.69 million, down from $22.55 million.

Manganese stockpile awaits conversion into revenue

At Ira Miri, the company completed what it described as Timor-Leste’s first hard-rock minerals extraction under the country’s modern Mining Code. The Stage 1 stockpile contains 27,371 tonnes grading 28.64% manganese, including 4,984 tonnes at 49.38% manganese. In-situ pit sampling recorded grades of up to 60.22% manganese, while the extraction campaign was completed with zero lost-time injuries.

That inventory is not yet a sale. Nine parties had expressed interest in purchasing some or all of the trial parcel by 30 June, but no binding sales agreement had been executed at that date. The company’s FY2027 plan says a customer has since been selected, with export documentation lodged and the sale conditional on government approval. The subsequent approval disclosed in the report was conditional, making the first shipment and the eventual realised price more important than the headline tonnage alone.

Werumata adds scale but remains an Inferred resource

Werumata supplies the other major operational milestone. Drilling returned average calcium carbonate grades of 83% in Baucau Limestone and 77.5% in Batu Putih Chalk, supporting a central resource estimate of 621 million tonnes. The resource is divided into 493 million tonnes aimed at acid-neutralisation markets, 33 million tonnes for industrial uses and 95 million tonnes for road base, construction aggregate and fill. All three products are described as direct-shipping material requiring crushing and screening only.

The qualification matters. Every tonne remains classified as Inferred, and the estimate covers only a small western portion of a concession extending more than six kilometres eastward. Estrella says a larger density sampling programme could support an upgrade in confidence, while further drilling, customer negotiations and port land access remain on its work programme. Its Master Agreement with PT Raka Energi Mandiri remains on foot, but is expected to be updated to reflect revised milestones before a definitive offtake arrangement can emerge.

Cash position keeps funding in the frame

Estrella held $5.24 million in cash at 30 June, down from $6.56 million a year earlier. Operating activities used $1.15 million, while investing activities absorbed $9.09 million, including $8.61 million on exploration and evaluation. Financing activities provided $9.36 million, including $10.01 million of application funds received in advance. The company explicitly identifies continued reliance on equity markets for exploration and development funding.

The next operating markers are unusually concrete: the first manganese shipment and sale, an approximately 3,000-metre Ira Miri drilling programme scheduled for October 2026, further Werumata drilling and progress on port access and customer agreements. Estrella also carries an ongoing legal dispute over its Mt Edwards lithium royalty and had 1.15 billion options on issue at the report date. The resource headlines are substantial; the balance sheet and execution timetable will determine how much of that scale becomes a business.
