Codelco to start lithium exploration at Salar de Maricunga, Chile
The exploration campaign will be carried out over a maximum period of ten months at the Maricunga salt flat.


17 Feb 2022

Chilean state-owned miner Codelco plans to start lithium exploration at the Salar de Maricunga salt flat in Chile’s Atacama Region by the end of next month.

The mining company received the last sector permit in January 2022 after securing an environmental permit to develop the salt flat in November 2020.

Codelco will undertake the exploration campaign at its mining property in the Maricunga salt flat, outside of the Nevado de Tres Cruces National Park, over a maximum estimated period of ten months.

Based on the concentrations of the discovered lithium, the company will determine its environmentally and economically viability to advance the project to the next development stages.

The Chilean miner expects the exploration work to unearth a high-grade reserve of lithium, an ultra-light metal, which is key for manufacturing batteries for electric vehicles, reported Reuters.

In a press statement, Codelco said: “It should be remembered that the National Policy for Lithium and the Governance of the Salars, issued in 2016, commissioned Codelco, together with the Ministry of Mining, to evaluate the feasibility of exploiting the existing lithium in the Salar de Maricunga, through public-public partnerships. private, considering the respect and care of the social, economic and environmental axes.”

Les Chinois annoncent avoir reperé un gros gisement de Lithium de spodumène dans les hauts plateaux du Tibet.

China scientists discover huge lithium deposit in Everest region
Bloomberg News | February 16, 2022

An official science publication in China is trumpeting what its quoted geologists called a “breakthrough” discovery of lithium in the same region as Mount Everest.


The hard-rock resource has the potential to host the third-biggest mine of its kind in China, according to ScienceNet.cn, a website backed by the Chinese Academy of Sciences, or CAS. It’s located some 3 kilometers from the Qiongjiagang peak in the region of the world’s highest mountain.

To be sure, it’s an early-stage discovery, and there’s plenty of global mineral deposits that look promising but end up not being viable.

But the world needs massive amounts of new lithium supplies to feed accelerating demand in electric vehicles and energy storage. And for China, finding viable domestic sources would be welcome as the country relies on imports for more than 70% of its supplies, even as it dominates global battery production.

The newly-discovered resource is a type of lithium-bearing rock called spodumene, an alternative to the brine lakes that dominate supply in China and in South America. The ore deposit on the Qinghai-Tibet plateau could hold as much as 1.0125 million tons of lithium oxide, according to the cited CAS geologists.

The project is still in the very first of four stages, with the final being full exploration to come up with a detailed mine plan, according to the report. The potential mine site is also far from the core nature reserve of Mount Everest and has suitable transport links, the cited experts said.

The media attention on this mineral find comes with prices of lithium rocketing higher amid tight supplies. Lithium carbonate in China gained more than 400% in China last year, and nearly 50% so far in 2022.

Finistère: 600 personnes contre une exploitation de lithium à Tréguennec

AFP•26/02/2022

Quelque 600 personnes se sont rassemblées samedi à Tréguennec, petite commune du Sud-Finistère, pour dire leur opposition à une éventuelle exploitation d'un important gisement de lithium, ce métal très recherché pour la fabrication de batteries, découvert sur un site naturel protégé.

"Nous craignons qu'un projet d'extraction de lithium puisse voir le jour à Tréguennec", a expliqué à l'AFP Stéphane Le Garrec, un habitant du secteur à l'initiative du rassemblement. "Aujourd'hui, il s'agit de marquer le coup, de montrer l'intérêt des gens pour le sujet et pour la protection de la biodiversité", a-t-il ajouté.
La page Facebook "Lithium à Tréguennec, Non, Merci!!!" dont il et à l'origine comptabilisait samedi, une semaine après son lancement, près de 9.000 membres.

Le gisement de lithium de Tréguennec a été révélé par le Bureau des recherches géologiques et minières (BRGM) en 2018, mais les récents propos de membres du gouvernement rapportés dans la presse sur une possible exploitation du métal ont déclenché l'inquiétude des habitants.

"Des ballons d'essai on en a déjà vus, à Plogoff notamment", a rappelé Viviane Gacquière, 50 ans, en référence au combat (1978-1981) victorieux des habitants du village breton contre un projet de centrale nucléaire.

"S'ils veulent renouveler leur petite expérience ici on ne se laissera de nouveau pas faire parce que le Bigouden, il est coriace", a-t-elle assuré, un panneau à la main sur lequel on pouvait lire "Nous ouvrons l’œil... la protection de la biodiversité est notre priorité".

"Tréguennec n'est pas à vendre!", "Non au lithium", ou encore "Appel à la vigilance, la tempête Pompili menace sur le gisement de lithium de Tréguennec", pouvait-on lire sur d'autres panneaux.

Interrogée par Les Echos, le 17 févier, la ministre de la Transition écologique Barbara Pompili avait affirmé que "la France doit extraire du lithium sur son territoire".

Le gisement se situerait sur le site d'une ancienne carrière, au niveau du lieu dit Prat-ar-Hastel, une zone de marais et de dunes classée Natura 2000. Ce serait le deuxième plus important de France après celui de Beauvoir (Allier).

Le lithium est un des composants les plus recherchés dans le monde actuellement pour la fabrication des batteries électriques automobiles, et son cours explose sur le marché mondial.

Projet de construction d'une mine de lithium en Arkansas :

Standard Lithium, Lanxess sign development deal for lithium project in US

By NS Energy Staff Writer 25 Feb 2022

Standard Lithium is expected to control all the for the development of the project, including the completion of the front end engineering design (FEED) study

Standard Lithium has entered into an agreement with Lanxess to advance the plan for the development of the first commercial lithium project in Arkansas, US.

The companies will collaborate on the construction of an operational Lanxess facility in El Dorado, Arkansas.

Under the deal, Standard Lithium is expected to control the development of the project, including the completion of the front end engineering design (FEED) study.

Standard Lithium will have a minimum of 51% majority equity interest in the project and can also own 100% of the project.

The firm will also hold 100% ownership of its South West Arkansas project, including extraction technologies, relevant intellectual property and know-how.

Standard Lithium CEO Robert Mintak said: “This agreement builds upon the successful working relationship that has been established between the companies.

“By entering into this Agreement, Standard Lithium takes ownership of the Project and its development timelines with a clear path towards delivering the first new commercial lithium production in the USA in over 50 years.”

Standard Lithium will establish an initially wholly-owned company to own 100% of the project during pre-FEED and FEED engineering studies. The FEED engineering will help conduct a NI43-101 definitive feasibility study (DFS) in the fourth quarter of this year.

Through a series of commercial agreements, Lanxess will accommodate the brine supply for the project and the project site lease. It will also be responsible for the rights of way, infrastructure, and other services related to the project.

Upon completion of a DFS, Lanxess will have an option to purchase an equity stake of up to 49% and not less than 30% in the project company.

Standard Lithium will hold 100% of the project, including customary dividends, distribution, or similar rights, in case Lanxess does not purchase an ownership interest.

In addition, the companies have agreed to jointly develop the second and third projects on the Lanxess properties.

Les permis environnementaux pour la mine de Lithium de Thacker Pass au Nevada sont finalisés :

Lithium Americas secures final permits for Thacker Pass lithium project in US

By NS Energy Staff Writer 28 Feb 2022

The water pollution control permit, mine reclamation permit and class II air quality operating permit are the three final permits approved for the Thacker Pass project

Lithium Americas has secured the final key state-level permits from the Nevada Division of Environmental Protection (NDEP) for its Thacker Pass lithium project in Humboldt County, Nevada, US.

The water pollution control permit, mine reclamation permit and class II air quality operating permit are the three final permits approved for the Thacker Pass project.

The permits have been approved after a 30-day public comment period and NDEP’s review of extensive input from the public.

NDEP carried out broad reviews of the mine site plan and verified the air models and calculations for the class II air quality operating permit.

The regulator has also evaluated needed bonding for land disturbance and reclamation under the mining reclamation permit.

In addition, the regulator assessed authorised mine operations and ore processing activities, including setting monitoring and reporting requirements, under the pollution control permit.

Lithium Americas president and CEO Jonathan Evans said: “With the final key state environmental permits in hand, Lithium Americas can begin to advance Thacker Pass towards construction.

“Thacker Pass provides an opportunity to enable a US-based battery supply chain for the growing electric vehicle market.

“Our commitment to developing Thacker Pass in the most environmentally responsible way is demonstrated from over a decade of conducting the necessary planning, design and engagement.”

Located at the southern end of the McDermitt Caldera, the Thacker Pass is said to be developed as an open-pit mining operation using conventional continuous mining equipment.

Recent drilling at the project suggested that the lithium mineralisation is considerable across the Caldera.

The company said that lithium-rich clays are expected to be in the range from a few metres up to 90m in the project area.

In October last year, Lithium Americas announced an increase in mineral resource estimate to 13.7 million tonnes

Rock Tech Lithium to build €400m lithium-hydroxide converter in Romania
The Romanian facility is one of the five lithium-hydroxide converters planned to be built by the Canadian cleantech company by the year 2029

By NS Energy Staff Writer 08 Mar 2022

Rock Tech Lithium has inked a memorandum of understanding (MoU) with the Romanian government to build a lithium-hydroxide converter in the country with an investment of €400m.

The new plant will produce materials for making lithium batteries used in electric cars. It is anticipated to produce enough lithium hydroxide per year that can be used for making batteries of 500,000 electric cars.

The planned Romanian lithium-hydroxide converter will be Rock Tech Lithium’s second facility in Europe after the €470m battery-grade lithium hydroxide production facility in Brandenburg, Germany.

Romanian Energy Minister Virgil Popescu signed the MoU on behalf of the government.

Popescu said: “I am very pleased that Romania will enter the map of large battery components manufacturers. Because, we must say, no battery can work without lithium. Basically, these refineries, these two refineries to be built in Europe, will make this lithium powder, one in Germany, one in Romania.

“Lithium is an energy resource. We are not talking at the moment of lithium exploitation, to probably anticipate a certain question from you about lithium exploitation in Romania, but we are talking about lithium brought from the mines in Canada.”

Rock Tech Lithium said that the Romanian facility is one of the five lithium-hydroxide converters it plans to build by 2029.

The Canadian cleantech company’s chairman Dirk Harbecke said that the Romanian project will create 700 new jobs, both directly and indirectly.

Presently, Rock Tech Lithium is scouting for a location for the construction of the lithium-hydroxide converter.

The Canadian company tweeted: “It took us almost two years to find and sign our first location in Brandenburg. To keep our ambitious targets, we need to plan wisely and long term.”

Rock Tech Lithium’s factory in Guben, Brandenburg is slated to start operations in 2024. Once commissioned, it can produce nearly 24,000 metric tonnes of lithium hydroxide per annum, which is enough to supply close to 500,000 electric cars with lithium-ion batteries.

Sayona reports upgraded resources for Quebec lithium projects

Canadian Mining Journal Staff | March 1, 2022

Australia-based Sayona Mining (ASX: SYA) has enhanced its position in North America’s lithium sector with new and upgraded mineral resource estimates for its flagship North American Lithium (NAL) and Authier projects in Québec.


Following independent studies by consultants BBA and SGS Canada, the JORC compliant (Australia’s equivalent to NI 43-101) lithium resource base for the two projects has approximately doubled to 119.1 million tonnes grading 1.05% Li2O (lithium oxide), for 1.25 million tonnes of Li2O. This was the first JORC resource estimate on the projects since their acquisition in 2021.


Meanwhile, the total Canadian NI 43‐101 measured and indicated resources increased to 87.8 million tonnes at 1.05% Li2O, for 919,900 tonnes of contained Li2O. Another 31.2 million tonnes at 1.07% Li2O for 334,200 tonnes Li2O were inferred.

The resource update represents the identification of the first underground constrained resources at NAL, taking advantage of higher grade mineralization at depth. Together with significant inferred mineralization within the open pit constrained estimation, this offers scope for further future resource increases under the NI 43‐101 reporting code, Sayona said.

“This expansion is a major achievement for Sayona as we further enlarge our leading lithium resource base in North America. Since the start of 2020, we have now grown our Quebec resource base nearly six times and with further increases expected soon from Moblan,” Sayona’s managing director Brett Lynch said in a news release.

“With lithium prices surging on the back of an increasing structural supply deficit, our upcoming definitive feasibility study for an integrated NAL‐Authier operation, expected in coming weeks, is set to show significantly enhanced profitability for the benefit of shareholders.”

The NAL project was acquired by the company and its joint venture partner Piedmont Lithium (ASX: PLL) in August 2021, after the asset was placed under creditor protection. The Authier project, with proven and probable reserves of 12.1 million tonnes grading 1% Li2O, also came with the NAL acquisition.

Soutien total à l'exploitation minière du lithium en Alsace

Sam 19/02/2022 Moteurnature

Il y avait des rumeurs, voici le temps de la confirmation. La première étape fut de vérifier qu'il y avait bien des ressources importantes de lithium sur le territoire français, c'est fait. Il y a des ressources en Alsace, à mi-chemin entre Haguenau et Wissembourg. Le premier site d'exploitation serait à Soultz-sous-Forêts. Il y en a aussi de l'autre côté de la frontière, et les allemands ont eux aussi le projet d'exploiter ces ressources, qu'on peut qualifier de vitales. Car ce n'est pas un quart, ni la moitié, mais 100 % des voitures électriques, qui possèdent une batterie lithium-ion. Elles auront peut-être demain des batteries lithium-air, le lithium va rester une matière première essentielle. Et quand on voudrait que toutes les voitures neuves soient électriques en 2035, les besoins sont énormes.

On s'était habitué à ce que le lithium provienne d'Amérique du Sud, ou d'Australie, d'endroits très reculés où personne ne va voir ce qu'il se passe, il est préférable pour l'environnement que cela soit ici, au plus près, sous le contrôle du code minier français, et des multiples règlementations européennes. Il y a aussi un potentiel minier pour le lithium en Nouvelle Aquitaine, et toutes les personnes qui sont proches des sites seront contre, comme beaucoup de gens sont contre les éoliennes, les centrales nucléaires, les sites industriels... Mais si on refuse tout, il faudra se passer de tout. Barbara Pompili, la ministre de l'environnement, s'est courageusement prononcée en faveur de l'exploitation minière en France dans une interview aux Echos, il faut la soutenir. La France vient d'enregistrer le pire déficit commercial de son histoire, le pays n'a pas les moyens de tergiverser.

South Korean steel manufacturer POSCO has commenced the construction of a new lithium hydroxide (brine lithium) plant in Argentina, with a total investment of around $839m.

The company is building the new plant at the Salar del Hombre Muerto salt-lake in Argentina.

POSCO Argentina, a wholly-owned subsidiary of the company, will carry out the construction and operation of the new lithium plant, along with its financing.

The new brine lithium plant will have a production capacity of 25,000 tonnes of lithium hydroxide per annum, which is adequate to address demand from 600,000 electric vehicles.

The construction is expected to be completed in the first half of 2024.

In addition, POSCO is planning to enhance the plant’s production capability to 50,000 tonnes from the end of 2024, by making additional investment in 25,000 tonnes per year.

Overall, the company aims to have a capacity of 100,000 tonnes by 2028 to address the demand for about 2.4 million electric vehicles.

POSCO is said to be the first in Argentina to produce lithium hydroxide through the complete process, from acquisition of mining rights, exploration, construction and operation.

In 2018, it acquired salt lakes in Argentina, in view of growing global lithium demand due to expansion of electric vehicle industry.

Brine lithium consulting company Montgomery & Associates has confirmed the presence of 13.5 million tonnes of lithium reserves in the saltlake, at the end of 2020

The possible mining activity at the prospect is expected to produce at least 2.8 million tons of lithium carbonate.

POSCO stated: “The currently skyrocketing price of lithium has reached five times the price when the lake was acquired (market price of $70,000 per ton of lithium).

“Considering the normal operating profit margin of 50% in the lithium mining industry, the lake is forecast to produce ten trillion won in accumulated operating profit.”

Recently, Reuters reported that Posco ia making $4bn investment in a new lithium mining project in Argentina, to address the increasing demand for rechargeable battery metal.

Atlantic Lithium annonce des ressources bien plus élevée en Lithium de spoduméne de Ewoyaa au Ghana.

Atlantic Lithium shares rise on new Ghana resource estimate

Henry Lazenby | March 24, 2022


A new resource estimate on the Ewoyaa lithium deposit in Ghana had expanded the compliant resource base by 42%. Credit: Atlantic Lithium.

The London-quoted equity of Atlantic Lithium has more than doubled over the past 12 months after the company reported on March 24 a new resource estimate on the Ewoyaa deposit in Ghana had expanded the compliant resource base by 42%.


Sitting within the company’s Cape Coast Lithium Portfolio, the West Africa asset now sports a Joint Ore Reserves Committee-compliant indicated and inferred resource of 30.1 million tonnes grading at 1.26% lithium oxide.

The company reports that additional resources come at essentially the same overall grade, which attests to the project’s “robust geological fundamentals.” This includes a 294% increase to 20.5 million tonnes at 1.29% lithium oxide in the indicated category and 9.6 million tonnes at 1.19% lithium oxide in the inferred category.

Atlantic reports mineralization remains open depth and along strike with additional untested pegmatites within the immediate deposit area, providing confidence for future resource upgrades.

The company is currently engaged in resource expansion and exploration reverse-circulation drilling with one drill rig active on site. On the regional front, auger drilling is underway with six rigs active over the portfolio, while a contract for undertaking a detailed airborne geophysical survey has been awarded. A soil sampling survey Is also underway over a newly granted Cape Coast licence.

Atlantic believes significant exploration upside remains within the broader 560 sq. km. Cape Coast lithium portfolio, which includes a historical resource estimate of 1.48 million tonnes at 1.67% lithium oxide at the Egyasimanku Hill deposit.

Atlantic believes the resource update can significantly improve existing project economics.

A December 2021 scoping study, based on 21.3 million tonnes grading 1.31% lithium oxide, delivered robust financial outcomes for a two million tonnes per annum operation, producing an average of 300,000 tonnes of 6% spodumene concentrate over an 11.4-year mine life.

Over this period, the operation is expected to deliver revenues exceeding $3.43 billion, with an after-tax net present value (8% discount) of $789 million and an internal rate of return of 194%.

Early estimates peg the pre-production capital at $70 million with a payback period of fewer than 12 months.

C1 cash operating costs have been estimated at $249 per tonne of 6% lithium spodumene concentrate free-on-board Ghana Port, after by-product credits.

Shares closed up 11.56% in London on Thursday at 47.3p apiece, taking the 12-month gain to more than 115%.
