Hudbay Minerals (TSX, NYSE: HBM) has secured permission from the British Columbia government to proceed with a three-phased expansion of its Copper Mountain mine that would extend the operation into 2040.

In a statement issued on Feb. 20, Hudbay said it has secured amended environmental permits issued by the BC Major Mines Office for the New Ingerbelle expansion project at Copper Mountain, one of the largest copper producers in Canada. Currently, the open-pit mine located 20 km south of Princeton is expected to run until 2033.

First Quantum pegs Argentina copper mine’s value at $5.9B

Frédéric Tomesco | February 20, 2026 |

A new technical report on First Quantum Minerals’ (TSX: FM) Taca Taca copper-gold project in northwest Argentina shows the project’s value has more than doubled in five years thanks in part to higher reserves and commodity prices.


Assuming an 8% discount rate, a copper price of $4.50 per lb. and a gold price of $3,000 per oz., Taca Taca has an after-tax net present value of $5.92 billion and an after-tax internal rate of return of 19.3%, First Quantum said late Thursday in a statement. That compares with the $2.36 billion NPV and 15.3% IRR that a March 2021 study had calculated.

“We see Taca Taca as an attractive project for First Quantum,” BMO Capital Markets analyst Matthew Murphy said Friday in a note.

Taca Taca is one of several mining projects that Argentina is counting on to lift economic output and close the gap with neighbouring Chile, the world’s leading copper producer. It would also help First Quantum, which is working to overcome the closure of the Cobre Panama copper mine, its main asset, by the Panamanian government.

Developing Taca Taca as an open-pit mine with an initial processing capacity of 40 million tonnes a year would cost about $4.2 billion, First Quantum estimates. Expanding capacity to 60 million starting in the fifth year of operation would cost an additional $1 billion. First Quantum’s 2021 study didn’t provide construction cost estimates.

Increased reserves

Located in the Puna region of Argentina’s Salta province, Taca Taca sits at an elevation of 3,500 metres, about 230 km west of the city of Salta and 55 km east of the Chilean border. No local communities live within or close to the project’s footprint.

Updated proven and probable reserves of 1.99 billion tonnes grading 0.42% copper, 0.01% molybdenum and 0.09 gram gold per tonne support an open-pit mine life of 35 years, First Quantum said. Contained metal stands at 8.43 million tonnes of copper, 244,400 tonnes molybdenum and 5.53 million oz. gold.

This represents a 13% increase in combined proven and probable reserves, a 9% rise in in-situ copper metal and a 9% climb in in-situ gold metal compared with the 2021 technical report. Mineralization remains open at depth and locally along the deposit margins to the south and east, First Quantum says.

Annual output over the first 10 years is pegged at 291,000 tonnes of copper and 133,000 oz. of gold at cash costs of 97¢ per pound. Production over the mine’s life is projected at 209,000 tonnes of copper and 96,000 oz. gold at cash costs of $1.26 per pound.

First Quantum plans to apply for financing under Argentina’s large investment incentives program, known as RIGI, over the coming months. RIGI, a creation of populist conservative President Javier Milei, is aimed at mining and energy projects with investments of more than $200 million.

Cuivre : MMG prévoit 400 millions $ en 2026 pour agrandir sa mine au Botswana

Agence Ecofin 06 mars 2026

Dans un contexte de hausse des prix et de boom anticipé de la demande mondiale de cuivre, les compagnies minières multiplient les investissements pour se positionner. Au Botswana, le groupe chinois MMG s’inscrit dans cette dynamique avec l’agrandissement de sa mine Khoemacau.

Au Botswana, la société minière chinoise MMG Limited a annoncé mardi 3 mars son intention d’investir 400 millions de dollars dans le projet d’agrandissement de sa mine de cuivre Khoemacau en 2026. L’objectif est de tripler le niveau de production actuel du site, afin d’atteindre 130 000 tonnes de concentré par an d’ici 2028.

Rachetée par MMG en 2023, Khoemacau constitue actuellement l’autre source de production industrielle de cuivre du Botswana, aux côtés de la mine Motheo de Sandfire Resources. Alors que sa production reste encore relativement modeste, avec 42 120 tonnes de cuivre extraites l’an dernier. La société a lancé début février le projet d’agrandissement dont le coût total est estimé à 900 millions de dollars. Le budget prévu pour 2026 doit permettre de faire progresser les travaux au cours des prochains mois.

Concrètement, pour atteindre le cap des 130 000 tonnes de cuivre, MMG prévoit notamment la construction d’une nouvelle usine destinée à doubler la capacité de traitement de la mine. Le programme inclut aussi des travaux destinés à étendre les opérations de Khoemacau à de nouveaux gisements tels que Mango et Zeta Nord-Est.

Selon MMG, ce projet constitue une « initiative stratégique visant à renforcer la rentabilité et l’envergure à long terme » de son portefeuille d’actifs cuprifères. Cette ambition s’inscrit dans un contexte favorable de hausse des prix du cuivre et d’anticipations de forte croissance de la demande, portée notamment par la transition énergétique et l’essor de l’IA. Côté botswanais, la mise en œuvre de ce projet débloque de nouveaux investissements pour l’industrie cuprifère en pleine émergence et la diversification de l’économie nationale, encore dépendante des diamants.

Comme pour tout projet minier, le succès dépendra de la capacité de MMG à mener le chantier à terme tout en respectant le calendrier annoncé. En parallèle, la société devrait poursuivre l’exploitation avec l’objectif de produire jusqu’à 53 000 tonnes de cuivre pour l’exercice en cours.
