Estrella makes history with manganese drill program in Timor-Leste
In mobilising a man-portable diamond rig from Dili to the Lautem region, Estrella says its joint venture (JV) with the East Timorese Government's Murak Rai Timor and drilling contractor CoreSearch marks the beginning of an intrepid new era for resource development in the South East Asian nation.
The inaugural hole is now underway, targeting manganese mineralisation just below an outcropping unit. The company has also started initial trenching to pinpoint the key geological contact within the Noni Formation.
The broader campaign will comprise an initial 3000 metres of diamond drilling and 10,000m of reverse circulation drilling, followed by a further 10,000m of reverse circulation drilling in a second phase after results start to roll in.
The campaign isn't just a technical achievement. Cultural integration has played a central role, with local elders blessing the site through traditional ceremonies. More than 40 members of the local community were also engaged in hand-clearing tracks to the drill pad.
Estrella has reinforced the tracks with machinery to ensure long-term access and erosion control. Follow-up drill sites have already been prepped 100m from the first line.
The project sits within Estrella's northernmost Lautem project area and includes multiple drill targets across the Ira Miri, Sica and Lalena prospects.
The initial drilling program will zero in on the manganese-rich zones mapped at Ira Miri.
Estrella has also set its sights on the region's broader mineral potential, including a large limestone deposit lying above the manganese horizon.
Two weeks ago, Estrella unveiled a landmark deal that could see up to 500 million tonnes of premium limestone shipped from Timor-Leste over the next five years, targeting South East Asia's surging industrial minerals demand.
The high-grade, coral-rich limestone sits atop the Baucau Formation within Estrella's 195-square-kilometre concession and directly overlies its manganese targets. This makes exploration doubly efficient as both resources can be assessed in tandem during drilling.
Recent assays have proved the limestone is a high-purity calcite with few impurities, meaning it could be perfect for use in cement, glass production, agriculture and as a key neutralising agent in nickel processing and environmental remediation.
Since drilling at Ira Miri will offer Estrella a first glimpse beneath the surface of Timor-Leste's largely untouched terrain, Estrella plans to release early manganese assays in June at the International Manganese Institute's conference in Tokyo.
The company and its government-backed JV partner see the event as a fantastic opportunity to spotlight Timor-Leste's emerging role in the global critical minerals sector.
Operations have been fast-tracked under a special approval from the Timorese mining regulator and broader environmental clearances are pending.
As the bit bites into fresh Timorese geology, Estrella is officially a first mover to unlock the nation's untapped mineral wealth. With drills spinning, support entrenched and geology onside, the company's Timor-Leste push could soon evolve into a game-changing discovery story.

Relief in Southeast Asia as Trump's tariffs level field
Southeast Asian countries are breathing a sigh of relief after the US announced tariffs on their exports that were far lower than threatened and levelled the playing field with a rate of about 19 per cent across the region's biggest economies. US President Donald Trump's global tariffs offensive has shaken Southeast Asia, a region heavily reliant on exports and manufacturing and in many areas boosted by supply chain shifts from China. Thailand, Malaysia and Cambodia joined Indonesia and the Philippines with a 19 per cent US tariff, a month after Washington imposed a 20 per cent levy on regional manufacturing powerhouse Vietnam. Southeast Asia - with economies collectively worth more than $US3.8 trillion ($A5.9 trillion) - had raced to offer concessions and secure deals with the United States, the top export market for much of the region. Malaysia's trade ministry said its rate, down from a threatened 25 per cent, was a positive outcome without compromising on what it called "red line" items. Thailand's finance minister said the reduction from 36 per cent to 19 per cent would help his country's struggling economy face global challenges ahead. "It helps maintain Thailand's competitiveness on the global stage, boosts investor confidence and opens the door to economic growth, increased income and new opportunities," Pichai Chunhavajira said on Friday. The extent of progress on bilateral trade deals with the United States was not immediately clear, with Washington so far reaching broad "framework agreements" with Indonesia and Vietnam, with scope to negotiate further. Thailand was about a third of the way there, Pichai said. The United States on Friday slashed the tariff rate for Cambodia to 19 per cent from earlier levies of 36 per cent and 49 per cent, a major boost for its crucial garments sector. "If the US maintained 49 per cent or 36 per cent, that industry would collapse in my opinion," Cambodia's Deputy Prime Minister and top trade negotiator Sun Chanthol said. In Thailand and Malaysia, business groups cheered a tariff rate that could signal a maintenance of the status quo between rival markets, among them beneficiaries of so-called "China plus one" trade. Much remains to be worked out by the Trump administration, including non-tariff barriers, rules of origin and what constitutes trans-shipment for the purposes of evading duties, a measure targeting goods originating from China with no or limited value added, where a 40 per cent tariff would apply. Vietnam has one of the world's largest trade surpluses with the United States, worth more than $US120 billion in 2024, and has been often singled out as a hub for the illegal rerouting of Chinese goods to America. It reached an agreement in July that slashed a levy from a threatened 46 per cent to 20 per cent, but concerns remain among some businesses that its heavy reliance on raw materials and components imported from China could lead to a wider application of the 40 per cent rate.

Atlassian co-founder Scott Farquhar urges Australia to embrace AI as firm strips 150 jobs
One of Australia's first tech billionaires has called for the nation to become the data centre capital of the Asia-Pacific in the global artificial intelligence race, just hours after the software firm he helped found sacked 150 employees to replace them with AI. Atlassian co-founder Scott Farquhar said individuals, companies and countries needed to embrace AI or risk falling behind, linking the technology as key to lifting lagging productivity. He envisaged Australia hosting 'digital embassies' where foreign nations could store their sensitive government data on our soil — but under their own foreign laws. 'Why host your foreign data in any other country when you could host it in Australia with cheaper power, faster build times under the laws of your own country,' he suggested, in a speech to the National Press Club. 'We could be the provider of choice for every government in the region and for every business that needs a Southeast Asian data centre.' Mr Farquhar's tech push on Wednesday came after Atlassian chief executive Mike Cannon Brookes told employees they were being replaced with artificial intelligence. When asked about the sackings Mr Farquhar —who stepped down as joint-chief executive of Atlassian in September but remains on the board — said job changes as a result of increased AI uptake across the sector was natural and shake ups at Atlassian occurred on a 'regular basis'. Mr Cannon-Brookes told the discarded workers in a video message rather than face-to-face just hours before attending the address to support Mr Farquhar. During his address Mr Farquhar, who is chair of the Tech Council, said Australia has significant advantages for AI development — including abundant land and energy potential, a strong legal system and strategic location. However, he brushed aside security concerns over Australia collaborating with China on AI, saying he wasn't a national security expert and that the issue was more complex. 'I'm not an expert on national security. I do believe that those things are very nuanced conversations. I think it's clear that our highest security partner is the United States, and our largest trading partner is China,' Mr Farquhar said He said the Australian government and tech firms should collaborate in embracing AI technologies, to progress the speed of technology rather than bureaucracy. Adding that if Australian businesses 'simply adopted existing AI tools, we'd see a major productivity lift'. 'Research, by the Tech Council that I'm chair of, shows this could add up to $115 billion a year, in addition to our economy by 2030,' he said. He called on unions to help support workers who lose their jobs through AI take up, by supporting new six to four month 'tech trade digital apprenticeships'. He described them as short, practical qualifications to get people ready for high demand industries like data centre construction and battery installation, adding they could be stepping stone modulus to full trades. Mr Farquhar also flagged copyright law reform as a key area for the Government to tackle. 'We need to make changes to our copyright laws. Australia's copyright laws are out of sync with the rest of the world,' he said. 'While the USA and Europe have exemptions for fair use, for text and data mining, and the Australian Law Commission in 2014 recommended changes, and Australian Productivity Commission in 2016 recommended changes. 'We remain an outlier when it comes to copyright. He called on the Attorney General Michelle Rowland to 'urgently amend' the Copyright Act to 'look at fair use and text and data mining exceptions'. He said changing the Act could unlock billions of dollars of foreign investment in Australia. 'This is a barrier to AI companies who want to train or host their models in Australia, and this is even a barrier to Australian born companies who want to build our models here.' In April last year, Mr Farquhar had announced his resignation as joint chief executive of Atlassian before officially stepping down in September 2024.
