London-listed NQ Minerals' ordinary shares are now dual listed on the Frankfurt Stock Exchange.

NQ is also working to seek admission to the Standard List on the London Stock Exchange's Main Market.

It is currently listed on a lesser London exchange, Aquis.

NQ - which recovers value from tailings from past mining at Hellyer, west of Cradle Mountain, and hopes to start actual mining in the area - said it was among the first companies with primary listings on Aquis to achieve a dual listing with the Frankfurt exchange.

" ... we are delighted to now be dual listed on the Frankfurt exchange, the biggest continental European stock exchange and the world's 12^th largest stock exchange by market capitalisation," NQ chairman David Lenigas said.

"The German investor audience is acutely tuned into the mining sector and green investment and has a deep understanding of the end markets that our sustainably extracted minerals impact as those sectors seek to reduce their carbon footprint."

NQ's gold recovery from material left by past miners at the Beaconsfield Wetlands and its Hellyer tailings reprocessing are both believed to provide environmental benefits.

Meanwhile, potential North-West miner ELEMENTOS LIMITED has told investors technical assessment of the best development pathway for its Cleveland Tin Project, between Waratah and Savage River, was under way.

It said a new, open cut, mineable resource at Cleveland was a game changer for a simplified, low-cost start-up development.

In a presentation for the RIU Resources Round-up Event in Sydney, Elementos said Cleveland had a "significant endowment" of tin-copper tailings, open cut and underground resources, plus a large tungsten porphyry exploration target below the tin deposit.

Elementos said exploration activities at Cleveland resumed in February amid surging tin prices.

Cleveland was operated as an underground mine between 1968 and 1986.

As well as its Tasmanian interests, Elementos is developing the Oropesa Tin Project in Spain.

In other mining news, Tasmania's bauxite miner is expanding its target area for rare earth elements in the state's North.

AUSTRALIAN BAUXITE LIMITED said a new sample from its DL130 bauxite project area west of Launceston had confirmed strong enrichment of super-magnet rare earth element neodymium.

The company has been exploring for rare earth elements for 15 months in its bauxite resources.
