Critica claims Australia’s biggest clay-hosted | Australian Markets

Critica Restricted has laid declare to Australia’s largest clay-hosted uncommon earths discovery after revealing a mammoth 1.8 billion tonne maiden world useful resource grading 1700 components per million (ppm) whole uncommon earth oxides (TREO) at its Jupiter project, which is a component of the company’s greater Brothers project in Western Australia.

The whopping useful resource, ready by unbiased world consultancy SRK Consulting, contains a precedence goal of 500 million tonnes working at 2200ppm TREO. With a exceptional cut-off grade of 1800ppm, the block is earmarked as high-grade.

Administration mentioned the near-surface and extremely constant nature of the globally vital deposit has opened a myriad of choices in the case of future processing and development situations.

The maiden useful resource has come sizzling on the heels of first go metallurgical testing that delivered an 830 per cent uplift in grade utilizing a easy, room-temperature flotation course of.

Take a look at work run over a number of samples of Jupiter’s mineralisation managed to elevate an initial grade of 1430ppm TREO into a exceptional high-grade focus of 13,310ppm TREO.

When 94.5pc of the fabric was eliminated, the remaining concentrated product nonetheless ran at an spectacular uncommon earth parts restoration fee of more than 50pc with out being additional optimised.

Critica is constant to run disciplined testing on the mineralised materials to spice up recoveries, helped by a well-regarded abroad specialist with expertise within the metallurgical idiosyncrasies that Jupiter has thrown up.

Whereas Jupiter shouldn’t be a traditional ionic clay deposit – favoured as a result of of the straightforward processing required – it’s clay-hosted.

The company says as a result of of its huge dimension, grade and proximity to main infrastructure, there may be each probability of discovering a comparatively low-cost processing resolution, when the metallurgists have solved the puzzle.

It’s extremely thrilling to have the ability to unveil Australia’s premier clay hosted uncommon earths deposit – the numbers communicate for themselves. Our maiden useful resource represents a main milestone that now we have, relatively remarkably, delivered in simply over a 12 months from saying the invention in November 2023.

Uncommon earth parts are essential in producing the high-performance magnets utilized in electric autos, wind generators and superior electronics. Jupiter accommodates a extremely precious subset of these parts, together with neodymium, praseodymium, dysprosium and terbium, which account for about 23pc of the full uncommon earth parts.

With $6 million within the bank as on the finish of December and most of the pricey drilling now accomplished, Critica seems to stay in uncommon financial health. It would transfer ahead within the subsequent few months with superior metallurgical testing and a few extra focused drilling throughout a number of satellite tv for pc deposits at Jupiter.

So as to add to its near-term funding choices, Critica has a tungsten-tin asset that has been languishing on the company’s guide for an extraordinary 18 years and is at present up for sale. It would doubtless be courting some sudden curiosity from potential patrons for the project, after China’s latest resolution to ban the export of tungsten amongst different metals in retaliation for US tariffs.

The Mount Lindsay project in Tasmania hosts one of the most important undeveloped tin deposits within the world, containing more than 80,000t of the steel in addition to a vital 13,000t tungsten useful resource.

With China decided to retain its tungsten for home use, 80pc of the worldwide provide of the gray steel has immediately evaporated, leaving western nations scrambling for various sources.

Critica has had a remarkably fast turnaround in fortunes lately.

The beginning gun was fired began after Leggat, the then newly appointed managing director, determined to pivot the company by focusing its efforts on the Jupiter grounds – a project which had been largely sitting within the “to do” file gathering mud.

Between promoting its Riley iron ore belongings in Tasmania, bringing two new sticky institutional traders onto the register with a $3.5m investment and raising a additional $6m in a placement, the company was in a position to high up the bank stability with $12m in new funds.

Critica then set about drilling 40,000m of exploration holes into Jupiter, ensuing within the largest ever clay-hosted discovery of uncommon earths in Australia.

All of this was achieved in little more than 12 months and for simply a bit more than $6m in exploration spend.

Punters are more likely to be hoping for a related repeat efficiency within the coming 12 months after the share price rallied 120pc in 2024. Critica appears to be having a red-hot crack at unlocking Jupiter’s metallurgical code – if it succeeds the punters are unlikely to be disillusioned.
