The project received regulatory approval from Peru's National Service of Environmental Certification for Sustainable Investments (SENACE). However, Teck is transitioning the project to asset preservation to evaluate opportunities to improve the business case before a final sanction decision. Early work activities were scheduled to cease in the first quarter of 2026, with contractors demobilising. A construction decision has been postponed.

The mine is expected to produce an average of 126,000 tonnes of copper per year over the first five years. Another source states the mine and concentrator are expected to produce an average of 133,000 tonnes of copper contained in concentrate during the first five years. An earlier estimate suggested an average of 76,000 tonnes per year of copper and 29,000 ounces per year of gold. Initial production was previously planned for 2028-2029.

The project plans to use a conventional concentrator plant. The process will involve crushing, grinding, flotation, thickening and filtering to produce copper-gold concentrates. The plant is designed for an average processing capacity of 64,000 tonnes per day (tpd), with the potential for up to 80,000 tpd.

The Environmental Impact Assessment (EIA) was approved in May 2023. A Feasibility Study was completed in 2019 and updated in January 2020. The project team is updating capital and operating cost estimates and developing detailed engineering plans. A formal project sanction decision could have been made as early as the first half of 2024. However, Teck has decided to postpone a construction decision to prioritise other investments. The project is being transitioned to "asset preservation" while opportunities to enhance the business case are evaluated.

The Zafranal Project is an open-pit copper and gold project in the Arequipa region of southern Peru, owned 80% by Teck Resources and 20% by Mitsubishi Materials. It received regulatory approval in May 2023 but was put into "asset preservation mode" and care and maintenance in March 2026, postponing a construction decision to prioritize other investments. Permitting, land access, and engineering design continue.

The Libby Exploration Project, formerly known as the Montanore project, is an underground stratabound sediment-hosted silver-copper deposit situated in Lincoln County, Montana. Operated by the United States mining company Hecla Mining Company, the project is currently in an advanced exploration and evaluation phase and is not in production. The current plan of operations, which has been authorised by the U.S. Forest Service, focuses on underground exploration to gather geological, hydrological, and environmental data to inform the project's future feasibility. This exploration phase involves the dewatering and rehabilitation of an existing adit, extending it by 4,200 feet, and constructing additional tunnels for data collection.

Production overview - 2025: silver 183346000 oz, copper 759420 t.

In October 2025, the U.S. Forest Service authorized Hecla's Plan of Operations, allowing underground exploration and evaluation activities to proceed for an expected 16 years. An optimistic estimate suggests 10 years before an actual mine is developed. In April 2026, environmental groups filed a lawsuit challenging the permit decision.

The Zafranal Project is a copper-gold project located in the Arequipa Region of southern Peru. The project is operated by Compañía Minera Zafranal S.A.C., which is a joint venture between Teck Resources Limited (80%) and Mitsubishi Materials Corporation (20%). In early 2026, Teck Resources announced the deferral of a construction decision for the Zafranal Project, placing it into "asset preservation mode". This decision was made to prioritise investment in its Quebrada Blanca mine in Chile. While the project's permitting, land access, and engineering studies will be maintained, initial works have been halted, and there is no clear date for a final investment decision.

Over the first five years of production, the mine is forecast to produce an average of 133,000 tonnes of copper contained in concentrate. The average annual production over the entire mine life is estimated at 76,000 tonnes of copper and 29,000 ounces of gold.

The extracted ore will be processed at a concentrator plant with a planned capacity of up to 80,000 tonnes per day. The processing method will involve crushing, grinding, flotation, thickening, and filtering to produce copper-gold concentrates.

The project is supported by approximately 30 full-time employees and a seasonal and contractor-based team. Project construction is estimated to create between 4,000 and 4,500 direct jobs over a five-year period. Once in production, it is expected to create an estimated 1,200 direct jobs.

Production overview - 2023: copper 12159 Mlbs, gold 9438 koz, silver 174086 koz.

The project is planned as an open pit mine and milling operation that will produce a high-quality copper-gold concentrate. The processing will use high flotation recoveries. The proposed slurry pipeline system to transport ore slurry from the Galore Valley Operations to the West More Tailings Management Facility will be approximately 63 km long.

The Galore Creek project is currently in the pre-feasibility stage. An updated Prefeasibility Study (PFS) is on track for completion in the fourth quarter of 2024, extended from an earlier 2023 deadline to allow for additional value engineering. A major regulatory approval process is expected to begin following the completion of the PFS. The project's existing Environmental Assessment Certificate was successfully modernized in early 2024 to support the resumption of access development. In September 2024, the Canadian government announced a conditionally approved investment of up to $20 million for the construction of a 43-kilometre access road for the project. A 2023 field program included 25,000 metres of drilling focused on resource expansion, geotechnical, and metallurgical studies to inform a Feasibility Study planned to start in 2024. The project is located within the territory of the Tahltan Nation, and a Participation Agreement was signed in 2006.

The construction of the Quebrada Blanca Phase 2 (QB2) project generated more than 30,000 jobs.

Quebrada Blanca is an operating open pit copper and molybdenum mine in Chile's Tarapacá Region. The Quebrada Blanca Phase 2 (QB2) project, a major expansion, includes a new concentrator and molybdenum plant, utilizing 100% desalinated seawater. The expanded operation began ramp-up in 2023.

Production overview - 2023: copper 56200 t; 2020: copper 13400 t.

The expanded operation includes a concentrator plant with a production capacity of 140,000 tonnes-per-day, which processes copper ore through crushing, milling, bulk flotation, thickening, and filtering. The operation is the first in the Tarapacá Region to use 100% desalinated seawater for all its production processes. A molybdenum plant was substantially completed in December 2023, with commissioning having commenced.

The mining fleet for the QB2 expansion includes Caterpillar 794AC electric drive off-highway trucks, which are autonomous-ready. The primary loading units are 58.1 m³ ultra-class electric rope shovels.

The Quebrada Blanca Phase 2 (QB2) project is a major expansion of the original mine. The project involved the construction of a new concentrator, a molybdenum plant, and associated infrastructure.

The Libby Exploration Project, formerly known as the Montanore Project, is operated by Hecla Mining Company. Acquired in 2016, it is located in Lincoln County, Montana. Currently under exploration, the project involves dewatering and extending an existing tunnel and constructing new tunnels over 16 years to determine economic viability and collect data. It holds an inferred resource of 112.2 million tons, with 183 million ounces of silver (1.6 oz/t) and 1.5 billion pounds of copper (0.7%).

If exploration is successful, a new Plan of Operations for a full-scale mine would need to be submitted and undergo a separate permitting process.

The NorthMet project is expected to create over 360 full-time operational jobs and 700 jobs during peak construction. As of late 2024, there were approximately 50 employees working on the project.

The project is a 50:50 joint venture between subsidiaries of Teck Resources and PolyMet Mining, which is majority-owned by Glencore. It combines the NorthMet and Mesaba deposits in Minnesota's Duluth Complex. The project is currently in the permitting stage and is facing legal and regulatory challenges. Several key permits have been revoked or suspended, and the Minnesota Department of Natural Resources has stayed its review of the Permit to Mine until at least August 2025. NewRange is studying potential changes to the project design, including increasing production from 32,000 to 40,000 tonnes per day, which could shorten the mine life from 20 to 15 years.

The processing plan for NorthMet involves crushing, grinding, and flotation to produce copper and nickel-copper concentrates. A second phase, which is optional, includes the construction of a hydrometallurgical plant to further process nickel sulfide concentrates.

The mining operation will use conventional truck and shovel methods. The processing plant for the NorthMet project will include a new semi-autogenous grinding (SAG) mill and a ball mill.

The Galore Creek project is currently in the pre-feasibility stage, with an updated study expected to be completed in 2024. A Feasibility Study is planned to start in 2024. In 2024, the project's existing Environmental Assessment Certificate was modernised to support the resumption of access development. A major regulatory approval process is anticipated to begin after the completion of the Pre-feasibility Study to assess proposed changes, including increased production and relocation of the Tailings Management Facility. The Province of British Columbia and the Tahltan Nation have signed a consent-based agreement for the joint assessment of the project. In September 2024, the Canadian government announced a conditionally approved investment of up to $20 million for the construction of a 43-kilometre access road for the mine.

Quebrada Blanca is an open pit copper, molybdenum, and silver mine in the Tarapacá Region, Chile. The original QB1 operation ceased supergene ore mining in 2018 and cathode production in Q4 2023. The Quebrada Blanca Phase 2 (QB2) project, inaugurated in October 2023, exploits deeper sulphide and hypogene mineralisation with a 140,000 tpd concentrator. QB2 is expected to produce an average of 316,000 tonnes of copper-equivalent per year for its first five full years.

Production overview - 2024: copper 207800 t; 2023: copper 64300 t.

The original Quebrada Blanca mine (QB1) exploited supergene copper mineralisation using heap leach, dump leach, and solvent extraction/electrowinning (SX/EW) processes to produce copper cathodes. Mining of the supergene ore ceased in 2018, and cathode production finished in the fourth quarter of 2023. The newly expanded Quebrada Blanca Phase 2 (QB2) project, which was inaugurated in October 2023, exploits the deeper sulphide and hypogene mineralisation. The process for QB2 involves a concentrator with a capacity of 140,000 tonnes per day, which includes crushing, milling, bulk flotation, thickening, and filtering to produce copper and molybdenum concentrates. The copper concentrate is then transported via a 165-kilometre pipeline to a new port facility for shipment. The operation also includes a molybdenum plant.

The mining fleet for the QB2 expansion includes the addition of 30 Komatsu 930E-4SE haul trucks to the existing fleet. The primary loading units are 58.1 m³ ultra-class electric rope shovels. The processing plant includes a primary crusher, overland conveyor, grinding mills, flotation cells, thickeners, and filters. PROK was engaged to manufacture and supply 57 engineered pulleys for the project.

The Quebrada Blanca Phase 2 (QB2) project is a major expansion that extends the mine's life and develops the sulphide resource underlying the original supergene deposit. The QB2 project was inaugurated in October 2023. The initial mine life of QB2 is 27 years, utilising only about 18% of the 2022 reserves and resources, which indicates significant potential for future expansions. A further expansion, the Quebrada Blanca Mill Expansion (QBME), is being advanced and is expected to start production in 2026, potentially increasing the mine's throughput by 15% to 25%.

The construction phase is expected to create approximately 2,900 jobs. Following construction, the ongoing operations will support around 1,500 direct jobs.

The HVC Mine Life Extension Project is a brownfield extension of Teck Resources Limited's existing Highland Valley Copper (HVC) Operations. The project is located at the current HVC site, which is approximately 17 kilometres west of Logan Lake and about 50 kilometres southwest of Kamloops in British Columbia, Canada. The project is designed to extend the life of the Highland Valley Copper operation from 2028 to 2046.

NuevaUnión is a major undeveloped copper-gold-molybdenum project located in the Atacama region of Chile. It is a 50/50 joint venture between Teck Resources Limited and Newmont Corporation. The project combines two large porphyry deposits, the Relincho (copper-molybdenum-silver) and La Fortuna (copper-gold), which are situated approximately 40 kilometres apart.

The 2018 PFS projected an average annual production over the first five years of 224,000 tonnes of copper, 269,000 ounces of gold, and 1,700 tonnes of molybdenum. A 2019 report mentioned a potential mine life of 38 years. More recent, albeit preliminary, estimates from 2024 suggest a potential annual copper production of 224,000 tonnes starting from 2034.

The initial development plan, based on a Preliminary Economic Assessment, involves a conventional open-pit mining operation. Ore from the La Fortuna deposit is planned to be transported via a conveyor to a single-line mill and concentrator facility at the Relincho site.

phased development approach is designed to reduce the initial capital investment, with future expansions to be funded by project cash flows.

In March 2026, Teck Resources announced its decision to postpone a construction decision for the Zafranal project, placing it into "asset preservation mode". This was done to prioritise investment at its Quebrada Blanca mine in Chile. Early work activities were scheduled to cease within the first quarter of 2026, with contractors demobilising from the site. Despite the pause, the company is continuing with the permitting process, land access, and feasibility and engineering studies. In January 2026, Peru's National Service of Environmental Certification for Sustainable Investments (SENACE) approved the project's second Technical Support Report, authorising modifications for project optimisation with an associated investment of US$21.2 million. This followed the approval of the first Technical Support Report in August 2025 for modifications valued at US$330 million. The project's Environmental Impact Study received approval from SENACE in May 2023. In September 2025, before the postponement, the company had aimed to start construction in 2026 with initial production planned for 2028-2029.

The mine is expected to produce copper-gold concentrates. Estimated average annual production is 76,000 tonnes of copper and 29,000 ounces of gold. Other estimates state an average of 126,000 tonnes of copper per year over the first five years, or an average of 133,000 tonnes of copper contained in concentrate during its first five years of production.

The project plans a conventional sulphide flotation concentrator with a processing capacity of up to 80,000 tonnes of ore per day.

The expanded operation, known as Quebrada Blanca Phase 2 (QB2), was inaugurated in October 2023. Ongoing optimization efforts are in place through a 'QB Action Plan' to address production constraints, particularly related to the tailings management facility, and to enable unconstrained production.

Approximately 27% of the operation's employees are women. In late 2024, new three-year collective bargaining agreements were ratified with two of the three labour unions at Quebrada Blanca, representing 78% of the workforce.

The Quebrada Blanca (QB) mine is a long-life copper operation located in the Tarapacá Region of northern Chile at an elevation of 4,400 metres. The ownership structure consists of Teck Resources Limited with a 60% interest, Sumitomo Metal Mining Co., Ltd. and Sumitomo Corporation with a collective 30% interest, and the Chilean state-owned company Codelco with a 10% non-funding interest. The Quebrada Blanca Phase 2 (QB2) expansion project develops the deeper sulphide resources that lie beneath the original supergene deposit. While first copper was achieved in March 2023, the ramp-up has faced challenges, particularly with slower-than-expected development of the Tailings Management Facility, which has constrained production. Despite this, the operation achieved design mill throughput rates by the end of 2024. The company is targeting a transition to steady-state operations in 2026. QB is a leader in sustainable practices, being the first in the Tarapacá Region to use 100% desalinated seawater for all its processes, and an agreement is in place to source 100% renewable power starting in 2025. A remote Integrated Operations Centre for the mine is located in Santiago.

Production overview - 2024: copper 207800 t; 2023: copper 56200 t.

The expanded operation includes a concentrator plant with a production capacity of 140,000 tonnes per day. The processing of copper ore involves crushing, milling, bulk flotation, thickening, and filtering to produce copper and molybdenum concentrates. Construction of the molybdenum plant was substantially completed in December 2023, and it was scheduled to be ramped-up in the second quarter of 2024. The operation uses 100% desalinated seawater, which is transported 165 kilometres from a port facility via a pipeline. Copper concentrate is also transported to the port through a pipeline. All major construction at the site, including the shiploader at the port, was completed in the first quarter of 2024. Cathode production from the legacy operation ended in the fourth quarter of 2023, and the plant is being decommissioned.

The mining fleet includes a fleet of Caterpillar 794AC electric drive off-highway trucks, which are being enabled for autonomous operation.

The initial mine life for the expanded QB operation is 27 years, which will utilise only about 15-18% of the 2022 reserves and resources, indicating significant potential for future growth. Teck is advancing the Quebrada Blanca Mill Expansion (QBME) project, a low-capital intensity optimisation and debottlenecking project to potentially increase throughput by a further 15-25%. The QBME project is expected to begin production in 2026.

The Libby Exploration Project, formerly the Montanore project, is an underground exploration project located about 20 aerial miles south of Libby in Lincoln County, Montana. It is operated by Hecla Mining Company, which acquired it in 2016. The project's purpose is to conduct underground mineral exploration and data collection to determine the economic viability of a silver and copper deposit. As of 31 December 2024, the project had an Inferred Resource of 112.2 million tons grading 0.7% copper and 1.6 ounces per ton silver. The United States Forest Service (USFS) issued a final decision notice and finding of no significant impact in October 2025, authorising the exploration plan to proceed. However, as of April 2026, the USFS decision is being challenged in court by a coalition of conservation groups. Hecla is also seeking a new water discharge permit from the Montana Department of Environmental Quality, which was expected in 2026.

Production overview - 2024: copper 1500000000 lbs, silver 183000000 oz.

Expected metallurgical recoveries are 88% for silver and 92% for copper.

The project plans to use an existing 7,000-foot adit.

The authorised Plan of Operations includes dewatering and rehabilitating an existing 7,000-foot adit. The plan involves extending this adit by 4,200 feet, with some reports suggesting an extension of nearly a mile. An additional 6,300 feet of lateral shafts would also be constructed to support exploration from approximately 25 underground drill stations. The project also includes expanding the existing waste rock storage area and building a second site. If exploration proves successful, a new Plan of Operations for construction and development would need to be submitted, triggering a new public permitting process.

The extension project is expected to create approximately 2,900 jobs during the construction phase. Ongoing operations will support about 1,500 direct jobs, an increase of 200 positions.

The Highland Valley Copper Mine Life Extension (HVC MLE) project is a brownfield extension of Teck Resources' existing Highland Valley Copper (HVC) Operations in British Columbia, Canada. Located about 17 kilometres west of Logan Lake and 75 kilometres southwest of Kamloops, it was formerly known as the Highland Valley Copper 2040 Project (HVC 2040). Construction commenced in August 2025, following receipt of an environmental assessment certificate and all required permits in June 2025, and board approval from Teck in July 2025.

The extension project is expected to yield approximately 1.95 million tonnes of additional copper from about 900 million tonnes of ore. Average annual copper production over the extended mine life is estimated to be 132,000 tonnes. Production for the existing operation was 98,800 tonnes of copper in 2023, 102,000 tonnes in 2024, and 127,100 tonnes in 2025.

The processing method involves autogenous and semi-autogenous grinding and flotation.

The mining fleet includes electric shovels and haul trucks. Teck has implemented autonomous haulage systems, with a fleet of 35 autonomous Caterpillar 793F models. The operation is also testing Shovel-Sense technology, which uses sensors on shovel buckets to analyse ore composition in real-time.
