Rio Tinto today unveiled a pathway for the ongoing development of the underground project at Oyu Tolgoi in Mongolia, one of the largest known copper and gold deposits in the world. The definitive estimate details how Oyu Tolgoi underground will achieve sustainable production for Panel 0 by October 2022 for development capital of $6.75 billion.

Rio Tinto and its partners, the Government of Mongolia and Turquoise Hill Resources (TRQ), need to continue to work together to finalise three other milestones the outstanding government approvals, funding and a power solution in order to ensure that the project can commence caving operations in 2021. This will unlock the most valuable part of Oyu Tolgoi, delivering significant benefits for the shareholders of Oyu Tolgoi and the people of Mongolia.

At peak production, Oyu Tolgoi is expected to operate in the first quartile of the copper cash cost curve 1 and by 2030 is expected to be the fourth largest copper mine in the world.

Oyu Tolgoi is expected to produce 480,000 tonnes 2 of copper per year on average from 2028 to 2036 from the open pit and underground, compared with 146,300 tonnes 3 in 2019 from the open pit. The underground Ore Reserve has an average copper grade of 1.52 per cent, which is more than three times higher than the open pit Ore Reserve, and contains 0.31 grammes per tonne of gold. 4 The size and quality of this Tier 1 asset provides additional expansion options, which could see production sustained for many decades.

Arnaud Soirat, Chief Executive of Copper & Diamonds said, “We now have a pathway to bring the underground project into production, which will unlock the most valuable part of Oyu Tolgoi. We will continue to work together with the Government of Mongolia and TRQ to progress the project, including finalising all necessary approvals and agreeing a solution on power and funding.”

Note to editors

Oyu Tolgoi is jointly owned by the Government of Mongolia (34 per cent) and Turquoise Hill Resources (66 per cent, of which Rio Tinto owns a controlling interest of 50.8 per cent). Rio Tinto has been the manager of the Oyu Tolgoi project since 2010.

The open-pit mine was completed in less than 24 months and production started in 2013. Since then, more than 240 million tonnes of ore have been milled, with over one million tonnes of copper in concentrate sold.

This announcement is authorised for release to the market by Rio Tinto’s Group Company Secretary.

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.
