Lithium Australia NL (ASX:LIT) was featured on Finfeed for the company’s development of “disruptive technologies for the sustainable and ethical production of battery materials.” The article also talks about Lithium Australia’s progress on its SiLeach® pilot plant in NSW, Australia, as well as its Front-End Engineering and Design (FEED) study.

According to the article:

The concentrates generated from Waste2 will be tested in a SiLeach® pilot plant located within the ANSTO Minerals facilities at Lucas Heights in NSW. The pilot plant is configured for operating conditions that reflect those of the latest SiLeach process, which includes recovery of lithium by way of phosphate precipitation.

The pilot plant run is set to kick off in early August. The aim is to produce lithium products to commercial specifications, using the data obtained during the test run to finalise FEED design criteria.

LIT managing director, Adrian Griffin, said: “Lithium Australia continues its war on waste. In processing the Waste2 material, we will clearly demonstrate that we can take the particular waste provided, run it through the SiLeach pilot plant and create a commercial lithium chemical.”

Resolution Minerals Ltd Drilling Program at Sunrise Gold Prospect Completed

Adelaide, Australia (ABN Newswire) – Resolution Minerals Ltd (ASX:RML) (FRA:NC3) is pleased to announce that it has completed the Company’s first drilling program on the Sunrise Gold Prospect at the 64North Project in Alaska. Drilling was conducted along an existing access road, targeting outcropping granite hosted mineralisation, analogous in style to Kinross’s Fort Knox Gold Mine, which is one of Alaska’s most profitable mines. The Sunrise Prospect was identified in 2020 by a RML trenching program and is located less than 5km from Northern Star’s operating Pogo Gold Mine.

Summary

– A 1400m long “fence line” of 27 shallow RAB drill holes designed to test outcropping mineralisation at the Sunrise Prospect has been completed.

Argyle Diamond Mine Closure: The End of a Sparkling Era

Pink and red diamonds are among the most special gems in the world. The value of these highly sought-after natural stones speaks for itself, but their rarity has arguably increased since the closure of Rio Tinto’s (ASX:RIO,LSE:RIO,NYSE:RIO) Argyle mine.

The asset, which ceased mining activity on November 3, 2020, had been in operation since 1983. In that time, 865 million carats of rough diamonds were produced.

The unique geological chemistry of the Western Australia location birthed the rarest hues, including champagne, cognac, blue, violet and of course, the coveted Argyle pink and red diamonds. Millions of carats of white diamonds were produced at the prolific property as well.

Graphite Metallurgical Test Work Update

Highlights:

  • Bulk sample of Springdale graphite concentrate estimated to be completed in Q2 2021.
  • Concentrate material will then be sent to Germany to test its amenability for the production of battery anode material suitable for use in EVs.
  • Final test results expected in Q3 2021.

Comet Resources Ltd (ASX:CRL) is pleased provide an update on ongoing test work on natural flake graphite from its Springdale Graphite Project (Springdale) located in Western Australia. Both excellent grade and recoveries were achieved on initial tests, leading to commencement of work to produce a bulk sample for further testing. Importantly, the graphite concentrates previously produced demonstrated a unique and potentially very valuable characteristic in its small size distribution, with two-thirds of the product passing the 38 µm size fraction screen. Generally, this small size fraction of graphite is a by-product of processing of larger flake fractions, which produces smaller size graphite, but in doing so also damages the smaller flake material in the process, reducing their performance and value. Deposits that contain high quality ultra-fine graphite are uncommon and are potentially suitable for supplying the expanding battery anode market, which continues to grow as the sales of electric vehicles (EVs) increase. Graphite suitable for battery anode production also achieves premium pricing in graphite markets, making it a highly sought-after product.

Medallion Completes Diagnostic Testing with Australian Nuclear Science and Technology Organization

Medallion Resources Ltd. (TSX-V: MDL; OTCQB: MLLOF; Frankfurt: MRDN) “Medallion” or the “Company”) announces completion of a suite of diagnostic test work at the Australian Nuclear Science and Technology Organization (ANSTO) in Sydney, to extract rare earth elements (REE) from mineral sand monazite. The monazite was sourced from an Australian mineral sand mine. Discussion is ongoing with additional prospective suppliers.

Mineral sand monazite is an abundant REE-rich feedstock, that can be accessed as a by-product from global mineral-sand mines that target zirconium and titanium, without the need for additional mining. Medallion’s business model is centered on the Medallion Monazite Process , a transferable and scalable technology designed to accept multiple mineral-sand monazite feedstocks and extract high-value REEs with high efficiency, high recovery and zero liquid waste.
