NorthWest Copper lifts Lorraine copper-gold resource

Henry Lazenby | July 27, 2022 |

NorthWest Copper Corp. (TSXV: NWST; US-OTCQX: NWCCF) has released a new mineral resource estimate on the Lorraine project, about 40 km. from the company’s Kwanika-Stardust project in Central British Columbia.


The June 30 technical report draws on drilling completed between 1949 and 2009 and calculates an indicated resource of 12.9 million tonnes for 156,093 lb. of copper, grading at 0.55% copper and 0.66% copper-equivalent.


The inferred resource is 45.2 million tonnes for 427,931 lb. of metal grading at 0.43% copper and 0.50% copper-equivalent.

“This updated mineral resource estimate adds to our overall copper-gold resource base with both size and good grades close to surface,” NorthWest Copper CEO Peter Bell said in a statement. “Our portfolio continues to deliver results, and the proximity of Lorraine to our flagship Kwanika-Stardust projects is significant.”

The company said the increased resource holds the potential for it to at least examine the potential for inclusion in a regional hub and spoke operation, given the shallow nature of the high-grade mineralization and its proximity to established access.

Un futur gisement minier au Canada, Colombie Britannique
Seabridge expects to invest $1.5bn in copper-rich underground mine at KSM

By NS Energy Staff Writer 04 Aug 2022

The company undertook a PEA study to assess a possible future expansion of the Canadian project to the copper rich Iron Cap and Kerr deposits

Seabridge Gold expects an initial capital cost of $1.5bn to develop a copper-rich underground mine at its fully-owned Kerr Sulphurets Mitchell (KSM) project in Canada.

As per the findings of a preliminary economic assessment (PEA) study, a sustaining capital of $12.8bn is needed over the 39-year mine life of the underground operations.

The Canadian firm said that the PEA was carried out to assess a possible future expansion of the KSM mine to the copper rich Iron Cap and Kerr deposits. The mine is located in northern British Columbia.

As per the study, Seabridge Gold will mainly focus on developing the Iron Cap block cave mine, which is complemented by a small open pit at Kerr.

Glencore va mettre 400 millions de dollars pour moderniser une raffinerie/fonderie de Cuivre (au Quebec) qui pollue actuellement beaucoup trop fortement l' air à l' Arsenic.
Glencore to invest more than $400m in Quebec copper smelter overhaul

By NS Energy Staff Writer 19 Aug 2022
The planned revamp of the Horne Smelter will reduce toxic emissions from the plant to a safer level by 2027

Glencore is set to invest C$520m ($403m) over a period of five years to modernise a copper smelter in northern Quebec, Canada.

According to a Bloomberg report, the planned revamp of the Horne Smelter is expected to reduce toxic emissions from the plant to a safer level by 2027.

Located in Rouyn-Noranda, the Horne Smelter is a custom copper smelter which processes concentrate and recycled material from Glencore’s mining operations and other parties.

This is the company’s only copper smelter in Canada. It employs 650 people.

A public health study that encompassed the period from 2005 to 2018 found arsenic levels at the site to be at 165 nanograms per cubic metre, which is 55 times the standard safe level.

Glencore North America head of copper operations Claude Belanger noted that the overhauling works will bring down the arsenic level to 15 nanograms by 2027.

Other works at the plant will include installing a high-capacity air cleaning system to capture dust and building a new energy-efficient casting wheel.

Belanger was quoted by the publication as saying: “It does not exist anywhere in the copper industry.

“It takes time to develop projects like that. These are new technologies. We want to improve environmental performance.”

According to Glencore website, Horne Smelter can process 820,000 tonnes of concentrates and recyclables per year. Its annual production capacity for anodes 210,000 tonnes.

The company is said to be in discussions with Quebec’s government for financial assistance regarding the investment.

Rio Tinto veut controler la totalité du projet Oyu Tolgoi
Rio Tinto sweetens offer price for Turquoise Hill Resources to $3.1bn

By NS Energy Staff Writer 25 Aug 2022

The British mining company increased its bid to $3.1bn, from an initial offer price of C$34 ($26) per share or a total of $2.7bn that was rejected earlier this month, citing the offer price is too low

Rio Tinto has improved its proposal to acquire the remaining 49% stake in Canadian mineral exploration and development company Turquoise Hill Resources.

The British mining company increased its bid to $3.1bn, from an initial offer price of C$34 ($26) per share or a total of $2.7bn that was rejected earlier this month.

By acquiring Turquoise Hill, Rio Tinto aims to gain direct control of a large-scale copper-gold mining project in Mongolia, dubbed Oyu Tolgoi.

Under the terms of the revised proposal, Turquoise Hill shareholders are expected to receive a cash consideration of C$40 ($31) per share, an 18% increase from its initial proposal.

The improved proposal is subject to customary closing conditions, including approval by a majority of the votes cast by Turquoise Hill minority shareholders, said Rio Tinto.

Rio Tinto chief executive Jakob Stausholm said: “Rio Tinto believes this offer not only provides full and fair value for Turquoise Hill shareholders but is in the best interests of all stakeholders as we work to move the Oyu Tolgoi project forward.

“We will continue to take a disciplined approach to capital allocation and strongly encourage the Board of Turquoise Hill to engage constructively, and to support and recommend in favor of Rio Tinto’s Improved Proposal.”

Rio Tinto’s initial proposal was rejected by the Mongolian government, which owns the 34% stake in Oyu Tolgoi property, citing the offer price as too low.

In addition, the initial offer had seen opposition from major Turquoise Hill shareholders, including Pentwater Capital Management, and SailingStone Capital Partners.

In December last year, Rio Tinto agreed to write off Mongolia’s $2.3bn debt to cover its share of the development costs for the Oyu Tolgoi copper-gold mine.

Earlier this year, the company ended a long-running dispute over the development of the Oyu Tolgoi underground project in Mongolia.

The capital expenditure (CAPEX) for the project development was estimated at $7bn, which has been increased by $300m from the initial $6.75bn, in December 2020.

Botswana : Sandfire peut produire jusqu’à 55 000 tonnes de cuivre par an (DFS) à Motheo

Agence Ecofin 30 aout 2022

Au Botswana, une industrie du cuivre émerge depuis quelques mois grâce à quelques projets phares. En dehors de la mine de cuivre Khoemacau entrée en production l’année dernière, on peut aussi citer le projet Motheo, dont la construction a débuté depuis quelques mois.

La compagnie minière Sandfire Resources a publié le mardi 30 août une étude de faisabilité définitive pour le projet d’agrandissement de la mine de cuivre Motheo, actuellement en construction au Botswana. Cette dernière devrait livrer 440 000 tonnes de cuivre sur 10 ans, avec un pic de production annuelle à 55 000 tonnes.

Cette estimation est basée sur l’exploitation du gisement A4 grâce à la construction d’une mine à ciel ouvert et l’augmentation de la capacité annuelle de l’usine de traitement de la mine. Elle devrait atteindre 5,2 millions de tonnes, contre 3,2 millions dans les plans actuels de Sandfire.

Notons que l’investissement total pour atteindre ces ambitions est estimé à 397 millions de dollars. Sous réserve de l’obtention des autorisations nécessaires, les premières livraisons de minerai devraient intervenir au dernier trimestre 2025.

Pour rappel, la première phase de l’exploitation de la mine de cuivre Motheo devrait débuter au cours du deuxième trimestre de l’année prochaine, avec l’entrée en production du gisement principal.

L' offre plus élevée de Rio Tinto sur Oyu Tolgoi a été jugée intéressante par Turquoise Hill Resources :
Rio Tinto signs agreement to acquire 49% of Turquoise Hill for $3.3bn

By NS Energy Staff Writer 01 Sep 2022

Upon completion of the transaction, Rio Tinto will have a 66% stake in Oyu Tolgoi a large copper-gold mining project in Mongolia, with the remaining 34% owned by the Government of Mongolia

Rio Tinto has signed an agreement in principle to acquire the remaining 49% stake in Turquoise Hill Resources, at a price of C$43 per share in cash, for a total of around $3.3bn.

The agreement marks the latest development in the company’s efforts to acquire Turquoise Hill, which gives direct control over the Oyu Tolgoi project in Mongolia.

Rio Tinto currently owns 102,196,643 common shares of Turquoise Hill, representing approximately 51% of the issued and outstanding common shares of Turquoise Hill.

The company also holds anti-dilution rights that allow it to acquire additional securities of Turquoise Hill to maintain its proportionate equity stake in Turquoise Hill.

Last month, it has increased its offer price to C$40 ($31) per share, from the initial price of C$34 ($26), which was rejected by the Mongolian government.

Rio Tinto said that C$43 per share is its best and final offer, and is unanimously approved by an independent Special Committee of Turquoise Hill’s Board of Directors.

Rio Tinto chief executive Jakob Stausholm said: “Rio Tinto is committed to moving Oyu Tolgoi forward in direct partnership with the Government of Mongolia to realise its full potential for all stakeholders.

“This agreement represents another significant step following the recent commencement of the underground operations, and will simplify governance, improve efficiency and create greater certainty of funding for the long-term success of the Oyu Tolgoi project.”

The transaction is planned to be implemented under the Business Corporations Act, and both companies intend to expeditiously finalise an arrangement agreement.

It requires approval of Turquoise Hill shareholders with 66.67% votes, and the approval of a majority votes from Turquoise Hill minority shareholders.

The transaction is expected to be completed soon after receiving approve of the Turquoise Hill shareholders, said Rio Tinto.

Upon completion of the transaction, Rio Tinto will have a 66% stake in Oyu Tolgoi with the remaining 34% owned by the Government of Mongolia.

Oyu Tolgoi is a combined open pit and underground copper and gold mining project, located 550km south of Mongolia’s capital Ulaanbaatar.

Rio Tinto Copper chief executive Bold Baatar said: “The transaction simplifies the ownership structure of Oyu Tolgoi and enables Rio Tinto to focus on working in partnership directly with Erdenes Oyu Tolgoi and the Government of Mongolia to create long-term value for all stakeholders.

Codelco voit sa production future de cuivre baisser en 2023.
Codelco’s copper output to fall further in 2023 — report

Reuters | August 31, 2022

Chile’s Codelco, the world’s largest copper producer, expects its output of the red metal to fall further next year amid project delays, local newspaper El Mercurio reported on Wednesday, citing the chairman of the state-owned miner’s board.

Codelco lowered its copper production outlook for 2022 to about 1.5 million tonnes last week, blaming lower recovery levels at some of its mines and ore grades at the Chuquicamata site.

The company previously had expected to produce 1.61 million tonnes of copper this year.

“The production outlook for 2023 is 1.45 million tonnes. For the five-year period between 2023 and 2027, the best forecast we have is 1.5 million tonnes on average,” Codelco Chairman Maximo Pacheco told El Mercurio.

Pacheco, who has been the miner’s chairman since March, said it was necessary to increase investments in “structural projects” that could offset the natural reduction in the mineral grades.

“To sustain future output, we have to develop projects that maintain that level of production and we’re facing difficulties in doing that,” he said.

“Structural projects are effectively behind schedule and over budget,” said Pacheco, describing discussions over the projects as a priority for Codelco’s board of directors. He did not provide further details.

Un prospect de Cuivre au Nevada : Elder Creek project
McEwen, Rio Tinto to jointly develop copper project in Nevada

Cecilia Jamasmie | September 6, 2022

McEwen Copper, a subsidiary of McEwen Mining , has inked a deal with Rio Tinto that gives the global miner an option to become a majority joint venture partner in the Elder Creek project, in Nevada.


To exercise the option, Rio’s subsidiary Kennecott Exploration would have to invest $18 million over a maximum of seven years. After that the two companies would form an unincorporated joint venture where Kennecott would be the largest partner and project operator.

Elder Creek is an early-stage copper-gold porphyry project, located about 9 km from SSR Mining’s Marigold mine complex in northern Nevada.

It consists of 577 unpatented mining claims in Nevada, which is prospective for porphyry copper mineralization and well placed in a district hosting several large copper and gold mines, including Marigold, Lone Tree and Phoenix.

McEwen holds a 1.25% net smelter return royalty on all the claims that comprise the Elder Creek property.

The company also owns Los Azules copper project in San Juan, Argentina. This is an advanced large-scale porphyry copper exploration project located in the Andean Cordillera copper belt, about 90 km (56 miles) north of Glencore’s El Pachón project and near the border with Chile.

L’offre mondiale de cuivre est menacée par une grève à la mine géante d’Escondida au Chili

Agence Ecofin 15 sept 2022

Le Chili est le premier producteur mondial de cuivre et la mine d’Escondida y contribue largement, avec environ 1 million de tonnes chaque année. Des perturbations dans la production sur cette mine sont donc particulièrement surveillées.

La menace de grève qui plane sur la mine de cuivre chilienne Escondida, la plus grande du monde, n’est toujours pas écartée. Au lendemain des deux jours de débrayage annoncés et finalement suspendus par les travailleurs cette semaine, aucun accord n’a été trouvé alors que ces derniers envisagent toujours un arrêt complet de travail.

Les employés avaient en effet déposé il y a quelques jours une motion de grève pour suspendre les activités 12 heures par jour le 12 et le 14 septembre, afin de protester par rapport aux conditions de travail non sécurisées à la mine. Peu de détails ont filtré sur le type d’accident craint par les mineurs, mais BHP assure avoir fermé de façon préventive les zones mises en cause.

Il faut dire que le sujet est délicat actuellement au Chili, après que la mort de deux travailleurs lors de la construction d’une mine en juillet a incité le président socialiste Gabriel Boric à envisager la ratification d’une convention de l’Organisation internationale du travail sur la santé et la sécurité dans les mines.

… comme en 2017 ?

Dépêchées sur place, les équipes de la Direction nationale du travail et du régulateur minier Sernageomin doivent rendre bientôt leurs conclusions. Si cette médiation échoue, l’approvisionnement mondial en cuivre sera forcément perturbé. Avec plus d’un million de tonnes livrées en 2021, Escondida représente en effet près de 5 % de l’offre totale, selon l’estimation sur la production minière mondiale faite par l’USGS pour l’année écoulée (21 millions de tonnes).

L’impact d’une potentielle grève sur la production de cuivre à Escondida reste encore à évaluer, et donc les conséquences au niveau des prix. Surtout que la demande mondiale est déjà affectée par le ralentissement de l’activité économique depuis quelques mois en Chine, premier consommateur mondial.

Cependant, les spéculations sur l’évolution de la situation peuvent pousser les prix vers le haut, comme c’est déjà arrivé jeudi dernier, quand des contrats à terme sur le métal rouge ont momentanément progressé de 4 %, après l’annonce de la grève cette semaine. La situation n’est pas sans rappeler celle de 2017, quand une grève de plus de 40 jours a favorisé la hausse des prix du cuivre sur le marché.

Plusieurs pays dont les économies dépendent du cuivre, comme la RDC et la Zambie en Afrique, devraient donc garder un œil sur le cas d’Escondida, dans l’espoir d’accroitre leurs revenus en cas de hausse durable des prix. Sur le London Metal Exchange le 14 août, le métal rouge s’est négocié à près de 7 900 $ la tonne, bien loin de son récent pic à plus de 10 000 $.

Philippine town revokes permit for Tampakan copper-gold project

Staff Writer | September 19, 2022

A local government in the Philippines has cancelled Sagittarius Mines’ permit for the Tampakan copper-gold project in the country’s South Cotabato province, citing concerns about the survival of hundreds of indigenous peoples that live nearby.


Tampakan, considered the Southeast Asian country’s biggest untapped copper-gold reserve, was stalled for over a decade following a 2010 ban on mining, which was extended to open-pit operations in 2017.

Former President Rodrigo Duterte, who ended his six-year term in June, lifted the nationwide ban late last year to revitalise the mining industry.

The move paved the way for Sagittarius Mines to reopen the $5.9 billion project, in which commodities giant Glencore used to have a controlling stake, but abandoned it amid regulatory uncertainties.

Mayor Leonard Escobillo of Tampakan told local press the permit had been revoked due the company’s “fraud, erroneous classification and misrepresentation of its business status.”

“There’s nothing personal in this case. We are just doing our job,” Escobillo told reporters.
The asset, which has estimated resources of 15 million tonnes of copper and 17.6 million ounces of gold, was one of at least 12 metallic mines expected to begin commercial operations this year.

Most of the mines awaiting permits are nickel projects, one of the metals in highest demand these days due to its use electric vehicles batteries and other devices that can help the world transition to cleaner technologies.

Tampakan was expected to have an average annual production capacity of 375,000 tonnes of copper and 360,000 ounces of gold in concentrate.

Rio Tinto sanctions $55m Kennecott underground mining project

By NS Energy Staff Writer 28 Sep 2022

The underground mining will bring an additional production of 30,000 tonnes of copper at the Kennecott project through the period to 2027

Rio Tinto has sanctioned an investment of $55m to begin underground mining at the Kennecott copper project located near Salt Lake City, Utah in the US.

The underground mining operations are expected to bring an additional production of nearly 30,000 tonnes of copper at the Kennecott project through the period to 2027, alongside the existing open pit operations.

The production of the first ore from the underground operations is anticipated in early 2023, while full production is targeted for the latter half of the year.

According to Rio Tinto, the produced ore will be processed through the existing facilities at the Kennecott project.

Initially, the underground mining will focus on the Lower Commercial Skarn (LCS) area. LCS has an estimated mineral resource of 7.5Mt at 1.9% copper, 11.26g/t silver, 0.84g/t gold, and 0.015% molybdenum.

Its probable ore reserve is 1.7Mt at 1.9% copper, 10.07g/t silver, 0.71g/t gold, and 0.044% molybdenum.

As part of underground development work, Rio Tinto is trialling the performance and suitability of the battery electric haul truck and loader supplied by Sandvik Mining and Rock Solutions at the Kennecott site.

The underground battery electric vehicles are expected to boost productivity and bring down carbon emissions from future underground mining fleets, said Rio Tinto.

Rio Tinto Copper chief executive Bold Baatar said: “This investment will allow us to quickly bring additional volumes of high quality copper to the market and build our knowledge and capabilities as we evaluate larger scale underground mining at Kennecott.

“We are progressing a range of options for a significant resource that is yet to be developed at Kennecott, which could extend our supply of copper and other critical materials needed for electric vehicles and renewable power technologies.”

Rio Tinto stated that feasibility studies are also being carried out to extend Kennecott open-pit mining operations beyond 2032.

The mining major also aims to complete a feasibility study on the next phase of underground production at the mine in 2023.

Anglo American begins commercial operations at Quellaveco copper project
The copper project in Peru is anticipated to yield 300,000 tonnes per year of copper equivalent volume on average over its first ten years


By NS Energy Staff Writer 27 Sep 2022

Anglo American has started the commercial operations at its Quellaveco copper project in Peru, which involved an investment of $5.5bn.

The launch of commercial operations follows the successful testing and final regulatory clearance, stated the mining major. Its first copper concentrate was produced in July 2022.

The Quellaveco copper mine is located 34km east of southern Peru’s Moquegua region.

Anglo American chief executive Duncan Wanblad said: “Our delivery of Quellaveco, a major new world class copper mine, is testament to the incredible efforts of our workforce and our commitment to our stakeholders in Peru over many years.

“Quellaveco alone is expected to lift our total global output by 10% in copper equivalent terms and take our total copper production close to 1 million tonnes per year.

“At a highly competitive operating cost, Quellaveco exemplifies the asset and return profile that is central to our portfolio quality and our ability to provide customers with a reliable and sustainable supply of future-enabling metals.”

The Quellaveco copper project is anticipated to produce 300,000 tonnes per annum of copper equivalent volume on average during its first ten years.

Anglo American said that it has revised the production guidance for the Quellaveco mine following a commissioning and testing period, and receipt of final regulatory clearance to between 80,000 to 100,000 tonnes of copper, compared with the previous target of 100,000 to 150,000 tonnes.

According to the miner, Quellaveco will be fully ramped up during the next nine to 12 months.

Anglo American base metals business CEO Ruben Fernandes said: “We designed Quellaveco as one of Anglo American’s and South America’s most technologically advanced mines, incorporating autonomous drilling and haulage fleets – a first in Peru – a remote operations centre, as well as a number of Anglo American’s digital and advanced processing technologies.

“Drawing its electricity supply entirely from renewables, Quellaveco is setting an example of a low emission mine producing a critical metal for decarbonising the global economy – copper.”

The Quellaveco copper project is owned 60:40 by Anglo American and Mitsubishi.

Copper Mountain Mining annonce une augmentation des ressources de Cuivre dans son projet en Colombie Britannique.
Ceci devrait permette une augmentation de production à 65 000 t de cuivre par an. Durée de la mine de 32 ans.
Pour le moment la mine produit 45 000 t de cuivre par an. ( open pit)
Copper Mountain nearly doubles BC mine resource to 1.1 billion tonnes

Copper Mountain Mining (TSX: CMMC) has announced updated mineral resource and reserve estimates for its 75% owned copper mine located in southern British Columbia. Based on the new reserves, the company has also provided a revised life of mine plan that supports a mill expansion scenario to 65,000 t/d from 45,000 tonnes per day.

The latest update sees the Copper Mountain mine grow its measured and indicated resources to 1.1 billion tonnes averaging 0.22% copper, 0.09 g/t gold and 0.64 g/t silver. Total contained metals of 5.5 billion lb. of copper, 3.4 million oz. of gold and 23.4 million oz. of silver each represent 70%, 68% and 62% increases over the previous estimate.

Included in the resources were proven and probable reserves of 702 million tonnes averaging 0.24% copper, 0.10 g/t gold and 0.71 g/t silver, for 3.7 billion lb. of copper, 2.3 million oz. of gold and 16 million oz. of silver.

Incorporating the updated reserve base, the Copper Mountain mine plan has been extended to 32 years with the 65,000 t/d expansion commencing in 2028. Annual production is projected at 114 million lb. of copper, 54,000 oz. of gold and 367,000 oz. of silver.

The revised life of mine plan also results in robust economics of $1.24 billion in after-tax net present value (at 8% discount), up from its previous estimate of $1.0 billion. The initial capital cost required to increase throughput to 65,000 t/d is estimated to be $237 million.

“These results illustrate the size and scale of the Copper Mountain mine,” says Gil Clausen, Copper Mountain’s president and CEO. “Our large mineral reserves base underpins our updated 65,000 t/d expansion study, which estimates total production of over 4.1 billion lb. of copper-equivalent over a mine life that will extend beyond 30 years.

“Increasing plant capacity to 65,000 t/d requires only modest initial development capital, which is self funded with mine cash flow. In fact, not only is the Copper Mountain mine able to fund capital required over the life of mine, but it is also expected to generate significant free cash flow beyond these requirements. In addition, higher-grade exploration upside remains, particularly at depth, providing further reserve expansion potential,” he adds.

With the new resource update, the company’s total mineral reserve base, including the Eva copper project in Australia, now stands at 5.4 billion lb. of copper and over 2.6 million oz. of gold.

The Copper Mountain mine is located 20 km south of Princeton, BC. Mitsubishi Materials owns the remaining 25% of the project.
