Le projet minier McIlvenna Bay au Canada semble avoir une ressource plus étendue :
Foran sees resource growth potential at Tesla discovery

Henry Lazenby | February 16, 2023

Foran Mining has released initial drill results from the 2023 winter program at the Tesla copper-zinc-gold-silver discovery, about 300 metres north of its McIlvenna Bay deposit in Saskatchewan.


Several intersections highlighted grades well above that contained in the McIlvenna Bay reserve estimate. McIlvenna Bay’s reserve is 25.7 million tonnes grading 2.51% copper equivalent.


At McIlvenna Bay, Foran aims for an underground mine to produce 38.8 million lb. copper, 63.6 million lb. zinc, 20,000 oz. gold and 486,000 oz. silver annually for the first 15 years.

Among the exploration highlights are 10.1 metres grading 4.62% copper-equivalent from 905.4 metres depth, including 3.4 metres at 8.29% copper-equivalent; 17.4 metres at 4.04% copper equivalent from 1,114.6 metres, including 2 metres at 9.47% copper-equivalent; and, 17.1 metres at 5.69% copper-equivalent from 1,205 metres, including 4.7 metres grading 7.73% copper equivalent.

Foran says preliminary data suggests Tesla and McIlvenna Bay may have been linked once, with additional drilling set to confirm the relationship. Other ground surveys are also planned.

The discovery remains open with opportunities for expansion through further drilling. Step-out hole TS-22-06A was drilled downdip to the east from the surface to a depth of 1,314 metres.

Additional assays from the Tesla Zone are pending.

BMO Capital Markets mining analyst Rene Cartier views the results positively. “In our view, Tesla is seen as a high-value target that remains open and is situated in very close proximity to McIlvenna Bay, which could support the scaling of future operations,” Cartier said in a research note.

Lancement du projet minier NewRange Copper Nickel dans le Minnesota
Teck, PolyMet launch NewRange Copper Nickel JV to advance Minnesota projects

Staff Writer | February 15, 2023

Teck and PolyMet have launched the NewRange Copper Nickel joint venture with the aim to supply critical minerals for the clean energy transition across North America. Together, they plan to become the second nickel producer in the US.

NewRange holds both the NorthMet and Mesaba copper, nickel, cobalt, and platinum group metal deposits, two significant clean energy critical mineral resources located in northeastern Minnesota.

The two resources contain measured and indicated resources of 637 million tonnes and 2 billion tonnes for NorthMet and Mesaba respectively, and additional inferred resources of 400 million tonnes and 1.3 billion tonnes respectively.

In total, the two assets represent approximately one-half of the known 7.25-billion-tonne Duluth Complex resource in northeastern Minnesota.

NorthMet is expected to produce 29,000 tonnes of ore per day over a 20-year permitted mine life, with first production targeted for 2026. Over its first full five years of operations, it is expected to deliver annual payable production of 30,000 tonnes of copper, 3,600 tonnes of nickel, 58,000 oz. of palladium, and 12,000 oz. of platinum. Estimates for Metsaba are currently unclear.

PolyMet and Teck are responsible for funding their pro rata share of costs related to the NorthMet and Mesaba projects. The owners have committed to an initial work program with an estimated budget of $170 million to maintain permits, update feasibility cost estimates, and undertake detailed engineering to position NorthMet for a development decision following permit clearances, and to advance Mesaba studies.

Glencore has committed to support PolyMet’s respective portion of NewRange’s initial $170 million work program and certain other costs and expenses in the amount of approximately $100 million.

“NewRange Copper Nickel has potential to be a modern, multi-generational operation that will support North America’s acceleration to a carbon-neutral future, build a better quality of life for people, and diversify and create significant economic benefits for northern Minnesota and beyond,” said Tannice McCoy, the newly appointed general manager of NewRange following a 21-year career with Teck.

Un prospect de Cuivre en Arizona dont j'ai pas encore parlé : Santa Cruz en Arizona
Ivanhoe Electric stock surges on Santa Cruz resource update

Staff Writer | February 14, 2023

Ivanhoe Electric has provided an updated mineral resource estimate for the Santa Cruz copper project located west of Casa Grande, Arizona, which now includes the first resource for the East Ridge deposit directly adjacent to the Santa Cruz deposit and for the Texaco deposit approximately 1.6 km to the northeast.

This resource update is based on much higher cut-off grades than the 0.39% used in the December 2021 resource statement to account for the consistency and thickness of the higher-grade exotic, oxide and enriched copper domains.

The resource at the Santa Cruz deposit reflects a 0.70% total copper cut-off, while the resources at East Ridge and Texaco reflect a 0.90% and 0.80% total copper cut-off, respectively.

Even at these higher cut-off grades, the overall project-wide contained copper in indicated resources increased by 11% to 2.8 million tonnes (226.7 million tonnes grading 1.24% total copper). Notably, contained copper in indicated resources, excluding primary sulphide mineralization, increased by 86%.

Project-wide contained copper in inferred resources also grew to 1.8 million tonnes (149 million tonnes grading 1.24% total copper), including 1.2 million tonnes of soluble copper.

The Santa Cruz deposit remains by far the largest deposit on the property, with indicated resources totaling 223.2 million tonnes grading 1.24% total copper and inferred resources totaling 62.7 million tonnes grading 1.23% total copper.

Notably, the deposit now includes 78% indicated resources at higher average grades than the previous estimate, which will form the base for the upcoming initial assessment/preliminary economic assessment.

The initial East Ridge and Texaco resource estimates reflect limited portions of the historically defined areas of mineralization, and represent what Ivanhoe Electric has delineated within the past six months.

According to the company, both East Ridge and Texaco exhibit significant potential for high-grade copper additions within the structural corridors that control the mineralization. Project-wide, Ivanhoe Electric currently has six diamond drill rigs active on site.

“We are making great strides towards our ambitious goal of constructing a low-carbon footprint, underground copper mine with minimal surface disturbance in Arizona,” executive chairman Robert Friedland said in a news release.

“This resource update is the culmination of a tremendous effort by our team at Santa Cruz. The drilling to date increases our confidence in the high copper grades at the Santa Cruz deposit and confirms the growth potential at the nearby East Ridge and Texaco deposits,” added CEO Taylor Melvin.

Shares of Ivanhoe Electric surged 11.3% to a near 52-week high of C$19.42 by 12:50 p.m. ET. The company has a market capitalization of about $1.4 billion.

RDC : Ivanhoe investira au moins 19 millions $ pour explorer le cuivre à Western Foreland en 2023

Agence Ecofin 24 fev 2023

En RDC, Ivanhoe exploite la mine de cuivre Kamoa-Kakula, codétenue avec le chinois Zijin et l’État congolais. La société canadienne détient également au moins 90 % d’intérêts dans le projet de cuivre Western Foreland, où elle a rencontré certains succès depuis le début de l’exploration en 2017.

En RDC, Ivanhoe Mines a fourni le jeudi 23 février une mise à jour pour son projet de cuivre Western Foreland, un actif qui s’étend sur 2 407 km², à proximité de son complexe cuprifère Kamoa-Kakula.

La compagnie minière canadienne a prévu un budget d’au moins 19 millions $ pour l’exploration sur cet actif en 2023, avec une partie qui sera consacrée à un programme de forage d’environ 70 000 m.

Comprenant des forages air core (AC) et au diamant (DD), ce programme soutiendra la publication d’une estimation de ressources minérales, d’ici mi-2023, pour les deux principales découvertes du projet, Makoko et Kiala. Une évaluation économique préliminaire sera ensuite lancée sur le projet afin d’estimer notamment l’investissement nécessaire pour son développement et les retombées financières potentielles.

Pour rappel, Ivanhoe Mines a lancé les travaux d’exploration à Western Foreland en 2017, découvrant le gisement Makoko, situé à environ 20 kilomètres à l’ouest du gisement de Kakula, l’année suivante puis celui de Kiala début 2020. Alors qu’il lui a fallu 24 ans pour produire le premier concentré de cuivre à Kamoa-Kakula, plusieurs facteurs invitent à l’optimisme concernant un délai plus court pour la mise en production du projet Western Foreland.

Outre la possibilité de s’appuyer sur l’expérience acquise avec Kamoa-Kakula et les installations de ce complexe de cuivre, la société peut compter sur l’explosion prévue de la demande de cuivre qui incite à des investissements accélérés dans la découverte et l’exploitation de nouveaux gisements. Ivanhoe Mines cherche d’ailleurs à attirer de nouveaux investisseurs pour financer le développement de ses activités en RDC.

RDC : la production de cuivre a augmenté de 31 % en 2022 (Banque centrale)

Agence Ecofin 13 fev 2023

La RDC demeure le leader incontesté de la production africaine de cuivre. En 2021, le pays a produit environ 1,8 million de tonnes de tonnes selon la Banque centrale.

La RDC a produit 2,36 millions de tonnes de cuivre en 2022, d’après les statistiques provisoires de la Banque Centrale du Congo publiées le mois dernier. Il s’agit d’une nouvelle hausse en glissement annuel, de 31 % cette fois-ci, confirmant une tendance qui s’est accélérée depuis 2019.

La production congolaise de cuivre est en effet passée de 1,22 million à 1,42 million de tonnes entre 2018 et 2019, avant d’atteindre 1,60 million en 2020, puis 1,79 million de tonnes l’année suivante. Si l’institution n’avance pas de raisons précises pour expliquer cette progression linéaire, on peut tout de même la rapprocher de l’entrée en production de plusieurs mines au cours de la période, dont celle de Deziwa en janvier 2020 et de Kamoa-Kakula en mai 2021.

Leader continental au niveau de la production de cuivre, la RDC peut nourrir désormais des ambitions à l’échelle mondiale en passant 3ème producteur du métal rouge devant la Chine, et juste derrière le Pérou dont la production a atteint 2,4 millions de tonnes en 2022. Le Chili reste le premier producteur mondial de cuivre avec plus de 5 millions de tonnes.

l' étude de pre-faisabilité du projet de Cuivre Molybdéne Vizcachitas au Chili est sortie :
Los Andes Copper unveils positive PFS for Vizcachitas project in Chile

By NS Energy Staff Writer 24 Feb 2023

The PFS estimates a post-tax net present value (NPV) of A$2.8bn, a pre-production capital cost of $2.4bn, with a construction period of 3.25 years, and costs are expected to be paid back within 2.5 years from the initial production

Los Andes Copper has announced the results of a positive Pre-Feasibility Study (PFS) at its fully-owned Vizcachitas porphyry copper project, located 150km north of Santiago, Chile.

Tetra Tech Sudamérica, a provider of engineering and consulting services for mining, and metallurgical processes has prepared the PFS.

The PFS estimates a post-tax net present value (NPV) of A$2.8bn, a pre-production capital cost of $2.4bn, with a construction period of 3.25 years.

The costs are expected to be paid back within 2.5 years from initial production.

The economics were calculated using the prices of $3.68/lb for copper, $12.9/lb for molybdenum and $21.79/oz for silver, said the company.

Los Andes Copper CEO Santiago Montt said: “I am extremely pleased to announce the results of the Pre-Feasibility Study for the proposed Vizcachitas mine in Chile.

“It shows that Vizcachitas is clearly a Tier 1 asset that has the potential to join the ranks as one of the largest and most profitable copper mines in Chile.

“The project is economically robust with the potential for considerable upside through further drilling to upgrade the Inferred Resource to Measured and Indicated, thereby bringing them into the mine plan.”

Vizcachitas project is located in the Andes Mountains, in the Province of San Felipe, Fifth Region of Chile, around 150km northeast of Santiago, Chile.

The project is a mineralised copper-molybdenum porphyry system associated with a complex of hydrothermal breccias and porphyries within Miocene volcanic rocks.

The PFS estimates the Proven and Probable Reserves of 1.22 billion tonnes at 0.36% copper, 136 ppm molybdenum, and 1.1 g/t silver, which equates to a copper equivalent (CuEq) grade of 0.41%.

The Measured and Indicated Resources increased by 16% to 14.8 billion lbs CuEq and Inferred Resource increased by 130% to 15.4 billion lbs CuEq, compared to the Preliminary Economic Assessment (PEA) dated June 2019.

Vizcachitas is expected to produce 8.8 billion lb copper, 273.3 million lb molybdenum and 32.7 million oz silver, in the initial life of the mine of 26 years.

The Chilean project is anticipated to produce around 183,000 tonnes of copper, at a cost of $0.93/lb copper, in the first eight years.

Los Andes Copper chairman Eduardo Covarrubias said: “The lack of new discoveries of this scale over the last 10 years and the increasing demand for copper highlights the importance of projects like Vizcachitas.

“The PFS demonstrates a robust, economically attractive project with long mine life and potential for significant further upside.

“The study focused on ensuring Vizcachitas would lead the way in sustainable mining, and we are delighted to announce that our three key targets: to reduce water usage, power consumption and the footprint of the Project have all been met, allowing us to deliver a mine that minimises its impact on the environment.”

Gros désaccords entre le minier First Quantum Minerals et le gouvernement du Panama au sujet de la mine de Cuivre Cobre Panama
First Quantum halts copper processing in Panama as dispute spirals

Cecilia Jamasmie | February 23, 2023

Canada’s First Quantum Minerals said on Thursday it had halted ore processing operations at its giant Cobre Panama copper mine, in the latest escalation of a dispute with Panama’s government over tax and royalty payments.

Negotiations between the Toronto-based miner and the country’s government over a new contract for the mine turned sour in December, when the President announced a plan to halt the operation.

The move, unusual among Latin American countries, came after the First Quantum missed a deadline to sign the new contract because it didn’t agree with the some of its terms.

Talks have continued since and, at times, they seemed to progress. Earlier this month, Panama’s maritime authority ordered First Quantum’s local unit Minera Panama to suspend loading operations at a major port, effectively blocking all exports from the mine.

The company was then asked to produce a third-party assessment confirming its scales have been properly balanced.

The miner, which said it submitted the proof on February 3, warned it would have to shut down the massive operation by mid-February because of limited storage capacity.

First Quantum has now begun a partial demobilization of its workforce of over 8,000 employees and contractors, it said on Thursday. It noted it expects the impact to increase significantly in the coming weeks if concentrate shipments do not resume.

In addition to workforce reductions, the mine has ceased purchasing supplies and services that are equivalent to $20 million in weekly revenues to more than 2,000 Panamanian companies.

“Panama has continuously demonstrated its commitment to hold talks based on good faith and trust,” the country’s Ministry of Commerce and Industries said in an emailed statement. “However, Minera Panama has demonstrated the opposite, as they have not honored their word and refuse to sign the agreement with the previously accepted terms, instead engaging in delay tactics that have lengthened the process for more than a year.”

The Cobre Panama mine’s union had called its members on Wednesday to strike against the halting of operations, arguing it would negatively impact workers.

Top copper mine

First Quantum is one of the world’s top copper miners and Canada’s largest producer of the metal. It churned out 816,000 tonnes of copper in 2021, its highest ever, thanks mainly to record output at Cobre Panama.

The Cobre Panama mine complex, located about 120 km west of Panama City and 20 km from the Atlantic coast, contributes 3.5% of the Central American country’s gross domestic product, according to government figures.

The asset is estimated to hold 3.1 billion tonnes in proven and probable reserves and at full capacity can produce more than 300,000 tonnes of copper per year, or about 1.5% of global production of the metal.

RDC : Kamoa-Kakula pourra livrer 450 000 tonnes de cuivre par an d’ici le deuxième trimestre 2023

Agence Ecofin 28 fev 2023

Pour sa première année d’exploitation complète, Kamoa-Kakula a livré environ 333 000 tonnes de cuivre en 2022. Le développement de ce complexe qui devrait bientôt devenir la deuxième plus grande mine de cuivre au monde, se poursuit avec l’augmentation de la capacité de l’usine de traitement.

En RDC, les activités de broyage ont augmenté de 22 % au complexe de cuivre Kamoa-Kakula pour atteindre désormais une capacité annuelle de 9,2 millions de tonnes de minerai. C’est l’annonce faite le lundi 27 février par le canadien Ivanhoe Mines qui précise que son actif est ainsi en bonne voie pour atteindre une capacité de production annuelle de 450 000 tonnes de cuivre au cours du deuxième trimestre 2023.

« L’équipe d’exploitation de Kamoa-Kakula continue de dépasser les attentes en livrant une fois de plus un important projet de croissance en avance sur le calendrier et le budget […]. Notre équipe d’ingénieurs dévoués est déterminée à poursuivre ce record d’excellence opérationnelle alors que nous exécutons la phase 3 de notre projet », a commenté Robert Friedland, coprésident exécutif d’Ivanhoe.

Pour rappel, la phase 3 du développement de Kamoa-Kakula permettra d’atteindre une capacité de production annuelle de 600 000 tonnes de cuivre d’ici début 2025. À titre de comparaison, la compagnie a produit 333 497 tonnes de cuivre en 2022 et vise une production de 390 à 430 000 tonnes à la mine cette année.

Panama and First Quantum agree on details for copper mine contract

Reuters | March 8, 2023 |

Panama’s government and Canada’s First Quantum Minerals agreed on the final text for a contract to operate a key copper mine, according to a statement signed by both parties Wednesday.


The new contract guarantees a minimum annual income of $375 million to the Central American government, and will be effective for 20 years with the option to renew for 20 more.

“With this contract, Panama expects to receive about ten times more than what it was getting” under the previous contract, the statement added.

The Canadian firm’s chief executive officer Tristan Pascall told Reuters he met with the Panamanian president after finalizing the text and ensured it guarantees “stable and durable” operations.

First Quantum paid $61 million in royalties to Panama’s government in 2021, while the Cobre Panama mine posted sales revenues of $3.2 billion for the year, company data showed.

Both parties agreed on all new economic terms, Pascall said in an interview.

The proposed concession contract is subject to a 30-day public consultation process and approvals by the Panamanian Cabinet, Comptroller General of the Republic and the National Assembly.

First Quantum suspended ore processing operations at the mine on February 23 after a government order halted its loading permissions at the port, limiting its capacity to store copper.

Panamanian authorities issued a resolution on Wednesday for First Quantum’ local subsidiary, Minera Panama, to resume concentrate loading operations, Pascall said, adding a ship will start loading within hours.

In 2021, Cobre Panama represented more than half of First Quantum’s earnings before interest, tax depreciation and amortization (EBITDA). It also accounts for about 3.5% of Panama’s gross domestic product.

First Quantum is working on bringing back the estimated 1,000 workers that were sent on leave while works were paused and expects to resume ore processing operations in the next few days.

Panama gives First Quantum go-ahead to operate port terminal

Reuters | March 11, 2023 | 6:25 pm Intelligence Top Companies Latin America Mexico and Central America Copper

Panama’s Maritime Authority has lifted a suspension on First Quantum Minerals’ operations at the port of Punta Rincon, which the Canadian company uses to export copper concentrate from its key Cobre Panama mine, company sources said late on Friday.


Two spokespersons for Minera Panama, First Quantum’s Panama unit, told Reuters the suspension dated Jan. 26 had been ended, which was confirmed by a source at the Maritime Authority.

The company, which spent weeks at loggerheads with Panama over Cobre Panama, had said that once the suspension ended, it would be able to resume activity at the port quickly.

The Panamanian government and First Quantum said on Wednesday they had agreed on the final text for a new contract on the operations of Cobre Panama, which accounts for about 3.5% of the country’s gross domestic product.

Because it could not work at Punta Rincon, First Quantum halted ore processing operations on Feb. 23 after reaching the maximum storage level of copper concentrate – about 10,000 tonnes – at the mine in Panama’s Donoso district.

About 60% of the copper concentrate exported through Punta Rincon is destined for factories in China. The rest is exported to other markets including Spain and Germany.

Rio Tinto keeps working to build Indigenous support for Resolution mine

Reuters | March 7, 2023

Rio Tinto Plc said it remains committed to building more support from an Indigenous group that opposes its Resolution mine project in Arizona, which could supply a quarter of America’s copper needs depending on the outcome of a court case.


Resolution is key to the Anglo-Australian mining giant’s future as the project would produce more than 40 billion pounds of copper for the green energy transition. But that copper sits below the federally owned Oak Flat Campground, a place some Apache consider home to deities.

The mine would create a crater 2 miles (3 km) wide and 1,000 feet (304 m) deep that would destroy that worship site, which the San Carlos Apache tribe strongly opposes.

A group of the world’s biggest copper producers said it aimed to slash direct and indirect greenhouse gas emissions to zero by 2050, in a move that could make the sector more attractive to environmentally-conscious investment funds.


With copper demand forecast to double to 50 million tonnes by 2050 from 2020 levels, the International Copper Association’s (ICA) roadmap released on Tuesday set a target for members to cut direct and indirect emissions by 30% to 40% by 2030, and by 70% to 80% by 2040, before reaching zero by 2050, it said.

Members include BHP Group, Chile’s Codelco, Glencore, Freeport-McMoRan, Japan’s JX Nippon Mining & Metals Corporation, and Poland’s KGHM.

There are no members from China, the world’s biggest producer of refined copper.

The copper producers plan to reduce direct and indirect emissions by decarbonising power supply, improving efficiency and scrap collection. Copper production from scrap metal can typically be done via electricity so is easier to decarbonise.

The ICA’s members will also work with customers to reduce their “scope 3” emissions by 10% by 2030, by 30% to 40% by 2040, and by 60% to 70% by 2050, it said.

“These collective ambitions show a clear trajectory to achieving defined emissions reductions of up to 85% by 2050, with the balance to be addressed through advanced technologies and enhanced collaboration,” the ICA said.

Emissions produced by the copper industry as a whole represent 0.2% of global greenhouse gas emissions. In 2018, the average emission intensity of refined copper production was 4.6 tonnes of carbon dioxide equivalent (CO2e) per tonne of copper, down by 13.4% from 5.4 tonnes of CO2e in 1990.

Given copper’s key role in the energy transition and the “ambitious” decarbonisation plans, the sector should be an attractive investment for funds that use environmental, social and governance (ESG) criteria, the ICA said.

Mongolie: début de l'extraction dans une gigantesque mine de Rio Tinto

AFP•13/03/2023

L'extraction dans une gigantesque mine de cuivre en Mongolie appartenant au géant anglo-australien Rio Tinto a débuté lundi après plusieurs années de différend autour du projet, a annoncé l'agence de presse du pays asiatique.

La mine d'Oyu Tolgoi ("Colline turquoise"), située en plein désert de Gobi et à moins de 150 kilomètres de la Chine, est considérée comme l'un des plus grands gisements connus de cuivre au monde.

Le site, qui devait initialement entrer en service en 2013, a fait l'objet d'une vaste controverse autour de son financement, du partage des bénéfices et de l'impact sur l'environnement.

Le géant minier Rio Tinto avait également pâti d'une montée du sentiment nationaliste dans la population mongole, inquiète de l'essor des firmes étrangères.

Après des années de retard, l'extraction a officiellement débuté lundi à 1.300 m de profondeur, a rapporté l'agence de presse Montsame.

L'événement a été marqué par une cérémonie en présence du Premier ministre mongol, Luvsannamsrai Oyun-Erdene, et du patron de Rio Tinto, Jakob Stausholm.

"Lorsque Oyu Tolgoi fonctionnera à pleine capacité, (le site) fournira suffisamment de cuivre pour produire plus de 6 millions de voitures électriques par an", a affirmé M. Stausholm, cité par Montsame.

Le site devait représenter pour la Mongolie une importante manne financière et peser plus de 30% de son produit intérieur brut (PIB), avaient affirmé les promoteurs du projet signé en 2009.

Oyu Tolgoi est déjà mis en valeur à ciel ouvert mais Rio Tinto assure que 80% des richesses du site résident dans ses réserves souterraines.

A l'issue d'un long bras de fer, Rio Tinto et la Mongolie avaient finalement conclu un accord en 2015 ouvrant la voie à l'exploitation et à de nouveaux travaux souterrains, qui avaient pris du retard.

Le groupe anglo-australien Rio Tinto possède, via Turquoise Hill, 66% de la société Oyu Tolgoi gérant la mine, tandis que les 34% restant sont détenus par le gouvernement de Mongolie.

Rio Tinto begins production from Oyu Tolgoi underground project

By NS Energy Staff Writer 14 Mar 2023
The underground project is an expansion of the existing Oyu Tolgoi mine in Mongolia, which has been producing through open pit operations since 2013


Rio Tinto has commenced production from the Oyu Tolgoi underground project in the Gobi Desert in Mongolia, which has involved an investment of over $7bn.

A ceremony to mark the milestone was attended by Mongolian Prime Minister Luvsannamsrain Oyun-Erdene and Rio Tinto chief executive Jakob Stausholm.

Rio Tinto holds a 66% stake in Oyu Tolgoi, while the remaining 34% is held by Erdenes Oyu Tolgoi, on behalf of the Mongolian government.

In January 2022, the parties ended a long-running dispute over the project and reached an agreement to reset their relationship and proceed with the Oyu Tolgoi underground expansion.

Rio Tinto said that 30 drawbells have been blasted and copper is currently being drawn from the underground mine.

Oyun-Erdene said: “I am proud to celebrate this major milestone with our partner Rio Tinto as we look towards Mongolia becoming one of the world’s key copper producers. The start of underground production at Oyu Tolgoi demonstrates our ability to work together with investors in a sustainable manner and become a trusted partner.

“The next phase of the partnership will enable the continued successful delivery of Mongolia’s ‘New Recovery Policy’ and Vision 2050 economic diversification strategy. Mongolia stands ready to work actively and mutually beneficially with global investors and partners.”

The Oyu Tolgoi underground project is an expansion of the existing Oyu Tolgoi copper and gold mine, which has been producing through open pit operations since 2013.

Through both open pit and underground operations, the Mongolian project is estimated to produce nearly 500,000 tonnes of copper per annum on average from 2028 to 2036. This will be adequate copper to help produce nearly six million electric vehicles annually.

The expansion project will result in an average of about 290,000 tonnes over the reserve life of nearly 30 years at the mine.

Ore from the underground project is presently being processed from Panel Zero in Hugo North Lift 1. Production is expected to be ramped up over the coming years, said Rio Tinto.

Stausholm said: “We are starting underground production 1.3 kilometres beneath the remote Gobi desert from an ore body that will be critical for global copper production and Mongolia’s ongoing economic development.

“The copper produced in this truly world class, high technology mine will help deliver the electrification needed for a net zero future and grow Rio Tinto’s copper business.”

je ne sais pas traduire Drawbells en français

meaning : Drawbells are the opening through which caved ore is extracted once the undercutting is completed. In the case of PMCHS, numerous drawbells will be required.
