Lucapa Diamond Company, owner of NT's Merlin mine, goes into administration
Australia's diamond industry faces an unlikely future as the company behind one of the few remaining projects in the country announces it has gone into voluntary administration.
The company that owns the Merlin diamond mine in the Northern Territory on Friday said administrators were now in control of operations.
In 2021, the ASX-listed Lucapa Diamond Company took over the Merlin project, 720 kilometres south-east of Darwin, but was yet to resume production.
While the Merlin site is famous for producing Australia's largest rough diamond, operators have not produced commercial quantities for more than 20 years.
There are no operating commercial diamond mines in Australia, veteran diamond specialist John Chapman says.
Rio Tinto's Argyle mine, which produced most of the world's pink diamonds, closed in 2020.
While there are several diamond projects in the exploratory stage, Mr Chapman said the Merlin site was the most advanced.
"It had been mined at some stage — in fact, it has the honour of producing Australia's largest rough diamond at 104 carats," he said.
"It does have the production, but clearly, it's just not economic, probably because of the depth of it.
When Perth-based Lucapa bought the Merlin diamond mine for $8.5 million, the company was optimistic about taking over the historic, large-stone producer.
"There are some 4 million carats in a resource that we have analysed and believe that we can extract economically for many, many years to come," managing director Stephen Wetherall said in 2021.
But since hitting a peak in 2022, the market for the gems has plummeted.
Lab-grown diamonds can be produced for a fraction of the asking price of their mined counterparts.
And while diamonds have uses beyond jewellery, the post-COVID global economic downturn has hit markets for luxury items.
"And that's not good news for any explorers trying to make a commercial venture out of any findings."
Richard Tucker from administrators KordaMentha said Lucapa's assets in the Merlin diamond project and a shareholding in an alluvial mine in Angola had "significant upside potential".
"Lucapa's management have developed a suitable pathway to development at Merlin … further upside exists through an exciting base metals opportunity on the Merlin tenements," he said in a statement.
But with such strong competition from synthetic gem producers, does Australia's diamond industry have a future?
"Probably the short answer would be no," said Mr Chapman, who has been in the diamond business for 35 years.
"It would be a long shot to say the diamond industry has a future in Australia – but you never know.
"Explorers are out there, you never know what they might stumble across, just like they did with Argyle 30 to 40 years ago."

‘Hopeium' of rate cuts and trade talks drives ASX 200 higher
Refreshed from the King's Birthday long weekend, the ASX 200 has surged to a new record close on Tuesday thanks to trade talks and renewed hope for a rate cut in July. The benchmark ASX 200 index surged 71.50 points or 0.84 per cent to 8,587.20, surpassing its previous record close of 8,555.8 set back on February 14. The broader All Ordinaries also jumped 70.80 points or 0.81 per cent to 8,812.70. The Australian dollar slid marginally during trading, but is still buying more than 65 US cents. On an overall strong day of trading 10 of the 11 sectors finished in the green led by the big banks, consumer discretionary and technology stocks. Zip was the best performing stock on the ASX 200 as it surged more than 6 per cent to $2.32, while Tabcorp shares jumped 5.71 per cent to $0.74 and Pilbara Minerals also jumped 5.46 per cent to $1.35. CBA continued to retest its own record highs, jumping a further 1.17 per cent to $182 with Australia's biggest bank now having a market capitalisation of $304.10bn. NAB shares jumped 1.53 per cent to $39.17, Westpac climbed 0.96 per cent to $33.50 and ANZ gained 1.12 per cent to $29.83. IG Market analyst Tony Sycamore said the banks were continuing their run up from the April lows on the back of falling rates spurring on the housing and credit markets. 'If rates fall back to 3.1 per cent, which is close to where we think neutral is for the RBA, that improves affordability which adds more demand for credit for the big banks,' he said. 'What happens to their margins? I don't think there's much of a difference between 3.85 or 3.1 per cent, there's still enough fat on the bone to make their generous profits.' The tech sector closed 1.6 per cent higher with shares in NextDC soaring 5.16 per cent to $13.86, while WiseTech Global jumped 2.36 per cent to $108.01 and Xero climbed 1.82 per cent to $192.10. On a heavy macro economic day, there were a number of factors driving the local bourse. In China deflation deepened to its worst level in almost two years in May, while US job figures came in hotter than expected although this was only due to the participation rate plummeting. There were also renewed hopes of a trade talk between the US and China, although US President Donald Trump said the discussions so far had been positive but 'not easy', while Treasury Secretary Scott Bessent called it a good meeting. Domestically, Australia's latest Westpac consumer sentiment index was released, showing Australians are feeling 'cautiously pessimistic.' Mr Sycamore said a combination of stronger than expected international news and renewed hopes of a rate cut domestically helped spur on the local market. 'When you put the weak China number together with weak consumer confidence in Australia and dig below the surface in the US job numbers, it is probably arguing for more rate cuts from central banks, which is probably the hopeium that drives these stock markets,' he said. 'Along with hopes of trade deals, that is why we are still near a record high.' In company news, shares in Monash IVF Group slumped 26.85 per cent to $0.545 after the fertility giant announced an embryo mix-up at its Melbourne laboratory, meaning the wrong embryo was implanted into a patient.

Closing Bell: ASX surges 0.84pc to record close, pushed higher by tech and banking stocks
ASX sets new record close at 8587.2 points, breaking February 2025 heights 10 of 11 sectors on the up, with only Industrials dragging (-0.08pc) All Tech and 200 Banks indices add more than 1pc each It's been a convincing day of gains on the ASX, coming straight from a trading break over the long weekend. The bourse had added 0.75% by midday and had nary a wobble through the day, climbing up 0.84% by the end of trade to set a new record high close at 8587.2 points. That beats the previous record set in February of 8555 points, and places the ASX just 0.33% from its 52-week trading high. Consumer discretionary led sector gains up 1.82% while industrials was the only sector to dip, losing just 0.08%. Standout stocks in the discretionary sector included Aristocrat Leisure (ASX:ALL), up 3.63%, JB Hi-Fi (ASX:JBH) + 2.05%, Light & Wonder (ASX:LNW) +3.54% and Tabcorp (ASX:TAH) +5.71%. Looking at the ASX indices, technology and the major 7 banking stocks generated the most momentum, climbing 1.6% and 1.18% respectively to outweigh the All Ords Gold index's 1.74% drop. Gold stocks were hit by an index shift from VanEck for its main GDX ETF, which from September will use a different index without exposure to Aussie mid-caps like Capricorn Metals (ASX:CMM) and Bellevue Gold (ASX:BGL), as well as less exposure to Newmont Corporation (ASX:NEM). Fineos Corporation (ASX:FCL) jumped 7.14%, NEXTDC (ASX:NXT) climbed 5.16% and WiseTech (ASX:WTC) added 2.34%. Six of the seven major banking stocks made gains, adding between 2.55% and 0.96%. The exception was QBE Insurance (ASX:QBE), which shed 0.13%.
