Column tests point Red Metal toward heap leaching at Sybella

Written by Industry Queensland on . Posted in All News, Critical minerals.

Column leach tests have strengthened Red Metal's (ASX:RDM) case for low-cost heap-leach processing at its Sybella rare earth project south-west of Mount Isa.

The tests used weak sulphuric acid at ambient temperature on coarsely crushed ore from the project's Kary Zone in North-West Queensland.

The company said the -10mm and -20mm samples recovered 70 to 76 per cent of neodymium and 71 to 78 per cent of praseodymium.

Ark Mines takes on FNQ rare earths project

Written by dev on . Posted in All News, Energy, Processing / Manufacturing.

Ark Mines has acquired the Sandy Mitchell rare earths project in Far North Queensland, with plans for a low-cost, fast start-up operation.

The company said rare earths at the project, about 230km north-west of Cairns, were amenable to panning a concentrate.

The Japan Organisation for Metals and Energy Security (JOGMEC) put in the groundwork in 2010, including undertaking particle mineral analysis, in addition to pan concentrates and more than 100 augur drill holes completed by other parties.

Ark Mines said the project contained all critical light rare earths as well as. . .

North West Minerals Province projects are being showcased to potential investors in South Korea and the United Kingdom this month in a new economy minerals roadshow.

Resources Minister Scott Stewart said the United Nations Climate Change Conference had intensified the focus on renewable energy and the materials central to the world’s energy transition.

State funds to spur rare earth phytomining work

Written by dev on . Posted in All News, Copper, Processing / Manufacturing.

A study into plants with a propensity to gather rare earths through 'phytomining' has attracted $1 million in backing from the State Government.

The University of Queensland’s Sustainable Minerals Institute is looking at whether certain types of native plants found at rare earth element-rich sites in Queensland can draw those metals out of the soil in high volumes.

Christmas dome at The Peaks project, NorthX

High hopes for standout rare earth project

Written by dev on . Posted in All News, Copper, Energy, Exploration, Gold, Processing / Manufacturing.

Scale rather than grade is the attraction of a very unusual rare earth deposit that explorer NorthX is preparing to drill in Central Queensland.

The Peaks project near Capella is based on peralkaline rhyolite formations in the shape of three raised volcanic domes.

NorthX exploration manager Stewart Parker said the only known similar deposit in the western world with this potential was Round Top in Texas, considered a strategically important project for the US.

NorthX has just received a Collaborative Exploration Initiative grant that will allow it to sink its first drill hole at the project in August.

Niche processing models for rare earth minerals

Written by dev on . Posted in All News, Copper, Energy, Gold, Processing / Manufacturing.

Hybrid models of rare earth minerals processing are likely to be the way forward as demand for niche elements increases.

Critical minerals used for defence, communications and renewable energy technologies among others, are a focus for Federal and State governments who are encouraging expanded exploration, mining, processing and manufacturing.

Potential resources have been identified in Queensland, particularly in the North West Minerals Province.

Associate Professor Paul Gow from the University of Queensland’s Sustainable Minerals Institute (SMI) recently addressed one of the largest industry conventions in the world, organised by Canada’s. . .

Rare earths in the spotlight as study probes copper-gold links

Written by dev on . Posted in All News, Copper, Exploration, Gold, Processing / Manufacturing.

The Mount Isa region is well positioned to ride the surge in rare earth interest, hosting both light and heavy rare earths associated with different types of mineralisation common to the area, a researcher says.

PhD student Ross Chandler is part of a team investigating why some copper-gold deposits in Mount Isa Inlier host rare earths while others do not in an Australian National University and Geological Survey of Queensland collaboration.

"It is something that really hasn't received a lot of attention - yet," Mr Chandler said.

"We are trying to tackle a number of the copper-gold deposits. . .

Spotlight on Queensland’s critical minerals might

Written by dev on . Posted in All News, Coal, Copper, Energy, Exploration, Gold, Processing / Manufacturing.

A raft of Queensland projects targeting critical minerals such as vanadium, graphite and cobalt are being promoted in an Association of Mining and Exploration Companies initiative.

AMEC has compiled an investment opportunities document to pique investor and company interests in the critical minerals sector domestically and internationally.

The document contains project information for a range of companies at various stages of development.

Queensland projects showcased include:

  • ActivEX's ESK & Coalstoun copper and gold project between Gayndah and Goomeri
  • Aeon Metals' Walford Creek copper-cobalt project, 340km north-north-west of Mount Isa
  • Alumtek. . .

‘Elegant solution’ to target rare earth concentrations

Written by dev on . Posted in All News, Energy, Exploration, Processing / Manufacturing.

University of Exeter researchers have revealed a new hypothesis to predict where rare earth elements neodymium and dysprosium could be found.

The elements are an essential part of digital and clean energy manufacturing, including magnets in large wind turbines and electric car motors.

Research led by Professor Frances Wall from the University of Exeter's Camborne School of Mines showed that sodium and potassium - rather than chlorine or fluorine as previously thought – were the key ingredients for making these rare earth elements soluble.

The experiments could allow geologists to make better predictions about where the best concentrations of neodymium and. . .

Centrex homes in on rare earth potential at Ardmore

Written by dev on . Posted in All News.

Centrex Metals is looking to put a figure on the rare earth potential at its Ardmore phosphate project as it gears up for a short mining campaign early next year.

In a company update today, Centrex said a preliminary study was underway into the potential for commercial quantities of rare earths at the North West Queensland deposit.

The value of these rare earths had not previously been included in economic modelling for the Ardmore project, it said.

The company remains in negotiations to raise funds for the further development of Ardmore.

Meanwhile it plans to appoint a mining contractor to. . .

Townsville leads the way in rare earths project

Written by dev on . Posted in All News, Energy.

Townsville-based academics will lead a research project on Australia’s endowment of rare earth elements. The Federal Government is providing $573,068 for the work, which will see James Cook University academics lead a team of experts from local and international universities and organisations, like Geoscience Australia and Northern Minerals. “Rare earth elements are growing in importance because of their use in batteries, mobile phones, medical equipment and other high tech products,” Federal Member for Herbert Phillip Thompson said.

Researchers tackle rare earth extraction

Written by dev on . Posted in All News, Copper, Energy, Exploration, Gold, Processing / Manufacturing.

A $920,000 Queensland project aims to give minerals explorers a 'toolbox' of approaches to improve extraction of rare earth elements (REE).

Researchers from UQ’s Sustainable Minerals Institute (SMI), Faculty of Engineering Architecture and IT (EAIT), and School of Environmental and Earth Sciences (SEES) are carrying out the work over four and a half years.

It is part of SMI’s Complex Orebodies strategic program and supported by the Geological Survey of Queensland through its New Economy Minerals Initiative.

Rare earths show potential at the Mount Isa Project

Written by dev on . Posted in All News, Copper, Exploration, Gold, Processing / Manufacturing.

Hammer Metals Limited (Hammer) has commenced a strategic review of the rare- earth-element (REE) potential of its Mount Isa Project as part of a broader asset review.

An initial investigation by Hammer of its drilling database has highlighted the potential of the Andy’s Hill iron oxide copper-gold (IOCG) prospect near Kalman and the Koppany prospect near Mary Kathleen for light REE’s specifically cerium, lanthanum, neodymium and praseodymium.

Neodymium and praseodymium are the core ingredients for the manufacturing of permanent magnets (NdFeB magnets), which are used in high-efficiency electric-motors and electric vehicles.
