Teck Resources
Teck Resources Limited is a Canadian mining company headquartered in Vancouver, British Columbia, focused on the production of copper and zinc metals critical for infrastructure, electrification, and the energy transition.[1][2] Originating from the 1913 incorporation of Teck-Hughes Gold Mines Limited in Ontario, the company expanded through acquisitions, including the 2001 purchase of Cominco Ltd., which bolstered its zinc and copper assets, and evolved into a major diversified resource producer with operations spanning Canada, the United States, Chile, and Peru.[3][4] In 2023, Teck separated its steelmaking coal operations into Elk Valley Resources, a move that rejected a takeover bid from Glencore and positioned the core business as a pure-play metals company emphasizing copper growth to meet rising demand from renewable energy and electric vehicles.[5][6] Key assets include the Red Dog zinc mine in Alaska, one of the world's largest of its kind, and the Highland Valley Copper mine in British Columbia, alongside development projects like Zafranal in Peru.[2] The company reports strong financial performance, with adjusted EBITDA reaching $1.2 billion in Q3 2025, driven by higher copper and zinc prices, though it revised downward its annual copper production guidance due to operational challenges at Highland Valley.[7][8] Teck has achieved recognition for operational scale and resource stewardship but encountered notable controversies over environmental impacts, particularly selenium contamination from its former Elk Valley coal mines affecting waterways like the Kootenay River system, leading to a $60 million penalty in 2021 under Canada's Fisheries Act for deleterious substance deposits.[9][10] In September 2025, Teck announced a proposed merger of equals with Anglo American plc to create a premier copper producer, subject to regulatory and shareholder approvals.[11]
Overview
Company Profile
Teck Resources Limited is a diversified mining company headquartered in Vancouver, British Columbia, Canada, specializing in the production of copper, zinc, and steelmaking coal.[12][13] The company engages in the full spectrum of mineral activities, including research, exploration, development, processing, smelting, refining, and reclamation of properties primarily in the Americas and Asia.[13] Its operations span world-class assets such as the Red Dog zinc mine in Alaska, Highland Valley Copper in British Columbia, and projects in Chile and Peru.[2] Founded in 1913 as Teck-Hughes Gold Mines, the company evolved through mergers and rebranding, operating as Teck Cominco Limited before changing to Teck Resources Limited in April 2009.[14][15] Jonathan Price serves as President and Chief Executive Officer, having been appointed on November 1, 2023.[16] Teck emphasizes responsible mining practices, targeting net-zero emissions and nature-positive outcomes through conservation and reclamation efforts exceeding mined areas.[1] As of December 31, 2024, Teck employs approximately 7,200 people, reflecting a reduction from prior years following the divestiture of its steelmaking coal business.[17] The company positions itself as a key supplier of critical metals for global development and the energy transition, with copper and zinc forming core segments post-coal sale.[1][4]Strategic Focus and Market Position
Teck Resources maintains a strategic emphasis on responsibly developing and operating long-life, world-class assets in copper, zinc, and steelmaking coal, prioritizing metals essential for global electrification, renewable energy infrastructure, and decarbonization efforts. The company's approach integrates operational excellence with sustainability imperatives, including targets for Scope 1 and 2 emissions reduction, water stewardship, and tailings management, while operating in stable jurisdictions such as Canada, the United States, Chile, and Peru to mitigate geopolitical risks.[18][19] Central to Teck's growth strategy is expanding copper production capacity, with a portfolio of high-return projects featuring lower capital intensity, such as the Quebrada Blanca Phase 2 operations in Chile, which ramped up in 2023 and contributed to projected copper sales increases of 25% to C$6.9 billion in 2025 driven by higher volumes and prices. This copper-led pivot reflects a broader reorientation from historical diversification toward high-demand base metals aligned with energy transition needs, including phasing out legacy structures like multiple voting shares to enhance governance.[20][21][22] A pivotal development in Teck's strategy occurred on September 9, 2025, with the announcement of a merger of equals with Anglo American plc, aiming to form a combined entity with enhanced scale in copper production—potentially positioning it as a top-tier global producer—and diversified exposure to critical minerals while retaining steelmaking coal assets. Sustaining capital expenditures for 2025 are guided at $1.0–$1.2 billion, supporting ongoing expansions amid volatile commodity cycles.[7][23] In the global market, Teck ranks as one of Canada's premier diversified miners, with a market capitalization of approximately $20.7 billion USD as of October 2025, underpinned by attributable copper production of around 300,000–350,000 tonnes annually and zinc output exceeding 600,000 tonnes. Its competitive edge derives from tier-one assets like the Red Dog zinc mine in Alaska—the world's largest of its kind—and Elk Valley Resources steelmaking coal operations, which supply premium metallurgical coal for low-emissions steelmaking, though the latter faces scrutiny over emissions profiles compared to emerging green alternatives.[24][25][12]History
Early Foundations
Teck-Hughes Gold Mines Limited was incorporated on September 26, 1913, by Norman Whitmore Teck to develop gold properties in the Kirkland Lake area of Ontario, amid the region's early 20th-century gold rush.[26][27] The venture capitalized on discoveries in northern Ontario, where placer and hard-rock gold mining had accelerated following earlier Yukon finds in 1896, though Teck-Hughes specifically targeted quartz veins in the Kirkland Lake camp.[3] Initial operations emphasized exploration and development of underground gold mines, with production ramping up as infrastructure like railways supported access to remote sites.[28] By the 1920s and 1930s, Teck-Hughes had established itself as a steady gold producer, contributing to Canada's position as a major gold exporter during periods of high metal prices driven by global economic demands.[3] The company's assets grew through acquisitions of additional mining claims and stakes in base metal prospects, diversifying beyond pure gold dependency amid fluctuating markets.[4] Through the mid-20th century, Teck-Hughes steadily expanded its portfolio of Canadian mining operations, including interests in silver and base metals, while maintaining gold as a core focus until post-World War II shifts toward broader resource development.[4] This foundational era laid the groundwork for Teck's evolution from a regional gold miner to a diversified entity, culminating in a 1963 restructuring into Teck Corporation Limited via merger with Canadian Devonian Petroleums, which marked the 50th anniversary of the original founding and signaled a pivot to larger-scale mining and petroleum ventures.[28][29]Key Mergers and Expansions
In 2001, Teck Corporation merged with Cominco Ltd., its majority-owned subsidiary, to form Teck Cominco Limited, integrating complementary zinc, copper, and coal assets and establishing the entity as North America's third-largest diversified mining company by market capitalization at the time.[30][31] The transaction, approved by shareholders on April 26, 2001, leveraged Teck's existing 50.1% stake in Cominco to create operational synergies in lead-zinc smelting and metallurgical coal production.[32] Teck further expanded its copper portfolio through the 2007 acquisition of Aur Resources Inc. for C$4.1 billion (US$3.9 billion) in cash and shares, adding high-quality assets including a 22.5% interest in Peru's Antamina copper-zinc mine and increasing annual copper output by over 91,000 tonnes immediately.[33][34] The deal, completed in September 2007 after regulatory approvals, diversified Teck's reserves and positioned it as a leading intermediate copper producer amid rising global demand.[35] A major foray into metallurgical coal came in 2008 with the C$14.1 billion (US$13.8 billion) acquisition of Fording Canadian Coal Trust, the largest coal deal on record at the time, which doubled Teck's exposure to seaborne steelmaking coal and integrated key Elk Valley mines in British Columbia.[36][37] The transaction, structured as cash and 0.245 Teck Class B shares per Fording unit and closing in October 2008, solidified Teck's role as the world's second-largest exporter of hard coking coal.[38] In a strategic pivot, Teck divested its steelmaking coal operations in 2023 by spinning off Elk Valley Resources and selling a 77% stake to Glencore for US$6.9 billion in cash, with additional interests to Nippon Steel (20%) and POSCO (3%), generating proceeds to fund copper expansions while retaining focus on critical minerals.[39][40] On September 9, 2025, Teck entered a merger-of-equals agreement with Anglo American plc to create Anglo Teck, a Canada-headquartered entity valued at approximately US$60 billion, combining premier copper assets like Teck's Quebrada Blanca and Anglo's Los Bronces to produce over 800,000 tonnes of copper annually post-synergies.[41][42] As of October 2025, the all-share deal—providing Anglo shareholders 62.4% ownership—remains on track for completion in 12-18 months pending regulatory approvals, including under Canada's Investment Canada Act.[7]Transition to Modern Operations
The 2001 merger of Teck Corporation and Cominco Ltd. formed Teck Cominco Limited, consolidating Cominco's leading zinc and copper assets with Teck's coal and copper operations to create a diversified mining powerhouse.[31] This integration enabled expanded production scales and technological synergies across North American and international sites.[43] In 2008, Teck Cominco streamlined its identity and structure by announcing a rebranding to Teck Resources Limited on October 1, with the legal name change effective April 23, 2009, alongside reorganization into five strategic business units for improved focus on coal, copper, zinc, and energy sectors.[44] This modernization emphasized operational efficiency and portfolio diversification, supporting investments in projects like the Fording River and Elk Valley coal expansions. Through the 2010s, Teck advanced modernization via automation, environmental controls, and large-scale developments such as Quebrada Blanca Phase 2, enhancing output while addressing sustainability demands. By the early 2020s, amid rising emphasis on critical minerals, Teck exited non-core assets including Alberta oil sands stakes in 2022.[45] In February 2023, Teck proposed spinning off its steelmaking coal unit to shareholders, aiming to refocus as a premier producer of energy transition metals like copper and zinc.[46] After navigating a Glencore acquisition bid, Teck sold its coal operations in 2024, completing the shift to a metals-centric model.[47] In August 2024, it adopted a new business structure as a pure-play energy transition metals company.[48] Further restructuring in January 2025 grouped assets into copper growth, zinc, and exploration units to prioritize energy transition materials.[49] On September 8, 2025, Teck entered a merger of equals with Anglo American, targeting over 70% copper exposure in the combined entity to capitalize on electrification demands.[41] This positions the post-merger Anglo Teck as a top-tier supplier of responsibly mined critical minerals.[50]Core Operations
Copper Production
Teck Resources maintains copper production operations across Canada and Chile, focusing on open-pit mining and concentration processes to yield copper concentrates, with some cathode output. Its primary assets include the wholly owned Highland Valley Copper mine in British Columbia, Canada, which produces copper and molybdenum concentrates via autogenous and semi-autogenous grinding followed by flotation; the 30% attributable interest in Quebrada Blanca (QB) in Chile, an open-pit operation with a concentrator designed to significantly expand output upon full ramp-up; and the 22.5% interest in Carmen de Andacollo in Chile, which generates copper concentrates from hypogene ore and cathode from oxide ore.[51][52][53] In 2023, Teck's attributable copper production totaled 297,000 tonnes. This rose to 446,000 tonnes in 2024, reflecting a 50% year-over-year increase driven primarily by the initial ramp-up at QB, which contributed substantially despite ongoing optimization efforts. However, production faced headwinds from tailings management issues at Highland Valley Copper and slower-than-expected QB commissioning, leading to revised quarterly outputs, such as 104,100 tonnes in Q3 2025 compared to 114,500 tonnes in the prior year's equivalent period.[54][23][7] For 2025, Teck adjusted its consolidated copper guidance downward to 415,000–465,000 tonnes from 470,000–525,000 tonnes, attributing the revision to persistent challenges at QB, including lower-than-planned output of 170,000–190,000 tonnes for that site alone, amid a comprehensive operational review and temporary halt on expansion pursuits to prioritize fixes. The company anticipates QB reaching 240,000–275,000 tonnes annually by 2027 under optimized conditions, underscoring copper's role in its growth strategy despite near-term constraints.[55][8][7]Zinc Production
Teck Resources ranks among the world's largest producers of mined zinc, with operations centered on the production of zinc concentrates from primary assets and refined zinc through downstream processing. Zinc in concentrate production reached 616,000 tonnes in 2024, supporting 35% of the company's total revenue that year.[56] The majority of output derives from the Red Dog Operations in Alaska, supplemented by attributable production from the Antamina mine in Peru, where Teck holds a 22.5% interest and zinc is extracted as a co-product alongside copper.[23] [56] The Red Dog mine, situated 170 kilometers north of the Arctic Circle in northwest Alaska, is Teck's flagship zinc asset, operated under a long-term lease agreement with the Iñupiat-owned NANA Regional Corporation established in 1982.[57] In 2024, Red Dog yielded 556,000 tonnes of zinc contained in concentrate, following 540,000 tonnes in 2023 and 553,000 tonnes in 2022, through open-pit mining methods involving drill-and-blast, truck-and-shovel extraction from sedimentary deposits.[57] The operation also produces lead concentrates and has an estimated mine life extending to 2031 based on current reserves.[57] Concentrates from Red Dog are shipped via sealift to global markets, including Teck's Trail facility and international smelters in Asia and Europe.[57] At Antamina, a joint venture in northern Peru, Teck's share of zinc production contributed to overall totals, with guidance for 95,000 to 105,000 tonnes in 2025, reflecting variability tied to the mine's copper-focused sequencing and ore grades.[23] This byproduct zinc is processed into concentrate at the site before export.[23] Refined zinc production occurs at Trail Operations in British Columbia, one of the world's largest integrated zinc-lead smelting and refining complexes, which processed concentrates into 256,000 tonnes of refined zinc in 2024 against an annual capacity of 295,000 tonnes.[56] Trail sources material from Red Dog and other suppliers, producing special high-grade zinc slabs registered on the London Metal Exchange, alongside alloys and die-cast products.[56] The facility employs hydrometallurgical and electrolytic refining to achieve high purity levels.[56]Steelmaking Coal
Teck Resources' steelmaking coal operations were located in the Elk Valley of southeastern British Columbia, Canada, and primarily involved four open-pit mines: Elkview, Fording River, Greenhills, and Coal Mountain.[58][59] These facilities extracted premium hard coking coal, characterized by low volatile matter, low ash, and high coke strength, suitable for the blast furnace-basic oxygen furnace process that accounts for approximately 72% of global steel production.[60] Teck positioned itself as the world's second-largest seaborne exporter of steelmaking coal prior to divestiture.[60] Annual production capacity reached 26 to 27 million tonnes, supported by proven and probable reserves of 831 million tonnes as of December 31, 2023.[61] In 2023, actual output totaled 23.7 million tonnes, surpassing revised guidance of 23.0 to 23.5 million tonnes due to operational efficiencies in the fourth quarter, where sales reached 6.1 million tonnes.[62][63] The coal exhibited among the lowest carbon intensities for the sector, benefiting from British Columbia's predominantly renewable electricity grid (97% low-carbon sources).[60] In a strategic shift toward copper and other critical minerals, Teck restructured its steelmaking coal assets via Elk Valley Resources (EVR). It first divested a 23% interest to Nippon Steel Corporation and POSCO in early 2023, then agreed in November 2023 to sell its remaining 77% stake to Glencore plc for US$6.9 billion in cash, implying an enterprise value of US$9 billion for EVR.[39] The transaction received final Canadian regulatory approval on July 5, 2024, and closed on July 11, 2024, after which Glencore assumed full operational control of the Elk Valley mines.[64][65] Consequently, Teck ceased steelmaking coal activities effective mid-2024, excluding them from 2025 production guidance.[23]Major Projects
Quebrada Blanca
Quebrada Blanca is an open-pit copper-molybdenum mine located in the Tarapacá Region of northern Chile, approximately 240 kilometers southeast of the port city of Iquique.[52] The operation includes a concentrator plant, tailings facility, utilities infrastructure, and a desalination plant for seawater use, with ore processing capacity of 140,000 tonnes per day.[66] Teck Resources holds a 60% indirect interest and acts as operator, with Sumitomo Metal Mining Co., Ltd. and Sumitomo Corporation collectively owning 30%, and the remaining 10% held by Chile's state-owned Empresa Nacional de Minería (ENAMI).[52] Development of Quebrada Blanca began with Phase 1 operations starting in 1994, focusing on initial copper extraction from oxide ores.[67] The project transitioned to sulfide ores, necessitating the major expansion known as Quebrada Blanca Phase 2 (QB2), approved for construction in 2019 with an estimated capital cost of approximately US$5 billion.[68] Construction faced delays due to COVID-19 impacts, leading to a suspension in 2020 and resumption later that year, pushing first production from the targeted Q4 2021 to 2023.[69] QB2 commissioning advanced with first copper concentrate produced on March 31, 2023, followed by an official inauguration in October 2023.[70][71] At full capacity, QB2 is designed to produce around 316,000 tonnes of copper-equivalent annually for the first decade, including copper and molybdenum byproducts, effectively doubling Teck's consolidated copper output.[71] Initial ramp-up targeted 285,000 to 315,000 tonnes of copper in 2024–2026, but operational challenges, including throughput constraints and equipment issues, prompted downward revisions.[70][72] In Q3 2025, mine output fell 24.6% quarter-over-quarter to 39,600 tonnes of copper, contributing to a 9.1% overall drop in Teck's copper production.[42] Updated guidance for 2025 lowered expected copper production to 170,000–190,000 tonnes from 210,000–230,000 tonnes, with impacts extending through 2028 due to persistent debottlenecking efforts.[73][8] The mine's estimated life is 27 years as of fiscal year 2023, supported by proven and probable reserves of approximately 1.4 billion tonnes of ore grading 0.41% copper.[74][67] Ongoing optimizations include potential synergies with the adjacent Collahuasi mine, owned by Anglo American and partners, amid Teck's proposed merger with Anglo American announced in September 2025, which could enhance regional efficiencies though joint venture dynamics with Sumitomo partners remain a factor.[41][75]Highland Valley Copper
Highland Valley Copper is an open-pit copper mine situated approximately 17 kilometres west of Logan Lake in south-central British Columbia, Canada. Teck Resources maintains a 100% ownership interest in the operation, which produces copper and molybdenum concentrates via autogenous and semi-autogenous grinding followed by flotation processing. The mine has historically processed large volumes of ore, supporting Teck's copper portfolio as one of its flagship assets.[76] Initial mining activities in the Highland Valley area commenced in 1962. In mid-1986, the Highland Valley Copper partnership was established through the consolidation of operations previously managed by Lornex Mining Corporation Ltd. and Cominco Ltd., enabling integrated development of multiple deposits in the region. This structure laid the foundation for expanded production under Teck's eventual full control.[77] Annual copper production at Highland Valley Copper has varied with ore grades and operational factors, recording 119,000 tonnes in 2022, 99,000 tonnes in 2023, and 102,000 tonnes in 2024. For 2025, Teck anticipates output between 120,000 and 130,000 tonnes, reflecting adjustments for lower-than-expected grades encountered in recent mining phases. The operation sustains around 1,500 direct jobs and contributes to local economic activity through procurement and community programs.[76][78] Teck approved the Highland Valley Copper Mine Life Extension Project in July 2025, committing $2.1 to $2.4 billion in capital expenditures to prolong operations from 2028 through 2046. Construction commenced in August 2025, encompassing Valley Pit pushbacks with additional waste stripping, expansions to the mining fleet, upgrades to the grinding circuit and tailings capacity, and enhancements to power and water systems. The project is projected to yield an average of 132,000 tonnes of copper annually over its lifespan, while generating approximately 2,900 construction jobs and an estimated $500 million in annual GDP during operations. All major environmental permits were secured in June 2025, marking this as British Columbia's largest investment in critical minerals development to date.[79][80]Red Dog Mine
The Red Dog Mine is an open-pit zinc-lead mine operated by Teck Resources, located approximately 170 kilometers north of the Arctic Circle in northwest Alaska, near Kotzebue.[57] It represents one of the world's largest zinc operations and the largest critical minerals mine in the United States, producing zinc concentrates that account for a significant portion of global supply.[81] The mine's concentrates are shipped seasonally via a winter ice road to the DeLong Mountain Terminal port for export to customers in Asia, Europe, and Teck's Trail smelter in British Columbia.[57] Development began in 1982 under an innovative operating agreement between Teck (then Cominco) and NANA Regional Corporation, an Iñupiat-owned Alaska Native entity that owns the subsurface mineral rights.[57] Commercial production commenced in 1989 following environmental permitting and infrastructure construction, including a 52-mile access road and concentrate storage facility.[82] The initial Main Pit was supplemented by the Aqqaluk deposit starting in 2010 to extend reserves, with the overall mine plan projecting operations through 2031 based on proven and probable reserves.[83] Mining employs conventional drill-and-blast methods with truck-and-shovel fleets, processing ore at an on-site mill to produce zinc and lead concentrates.[57] Annual zinc production has averaged over 500,000 metric tons in recent years, with 555,600 tonnes mined in 2024 despite planned grade declines.[84] Comparable figures include 540,000 tonnes in 2023 and 553,100 tonnes in 2022, alongside lead output of approximately 60,000-70,000 tonnes annually.[57] For 2025, Teck guidance forecasts 430,000-470,000 tonnes of zinc due to lower ore grades in the mine sequence, with third-quarter 2025 output at 122,000 tonnes of zinc and 27,400 tonnes of lead.[23] [85] The operation generated $2.059 billion in revenue in 2024, reflecting its economic scale.[57] Teck and NANA maintain the Traditional Resource Initiative (TRI), a collaborative framework established to monitor and mitigate impacts on subsistence resources like caribou, aligning mining with local Iñupiat cultural practices.[86] This partnership supports approximately 715 jobs in the Northwest Arctic Borough, annual wages of $75 million, and local spending exceeding $160 million, fostering economic development in remote communities.[87] In 2024, Red Dog achieved Zinc Mark verification, certifying responsible production practices for its zinc output.[88]Elk Valley Operations
The Elk Valley Operations represented Teck Resources' primary steelmaking coal mining activities in the Elk Valley region of southeastern British Columbia, Canada, encompassing open-pit extraction of metallurgical coal essential for steel production.[58] The operations included four key mines—Elkview, Fording River, Greenhills, and Line Creek—located near communities such as Sparwood, Fernie, and Elkford, with reserves supporting long-term production through large-scale surface mining methods.[89] [90] Coal extraction in the Elk Valley dates to the late 19th century, with underground mining predominant until the shift to open-pit operations in the 1960s, enabling higher volumes for export markets.[59] Teck consolidated control of these assets in October 2008 via the acquisition of Fording Canadian Coal Trust and related partnerships for US$14 billion, integrating them into its steelmaking coal division and positioning the company as the world's second-largest seaborne exporter of the commodity.[91] Elkview Operations, for instance, initiated production in the early 1900s and expanded under Teck to yield consistent output of premium hard coking coal.[90] Annual production from these mines reached 21.5 million tonnes of steelmaking coal in 2022, rising to 23.7 million tonnes in 2023 amid operational optimizations and market demand.[92] [62] Facilities featured advanced processing plants for washing and beneficiation, with rail transport via Canadian Pacific and BNSF lines facilitating exports primarily to Asia and Europe.[60] Economically, the operations generated substantial regional impact; as of 2020, Fording River alone contributed approximately one-third of Teck's $3.9 billion in cumulative economic benefits to the Elk Valley, including jobs, infrastructure, and royalties.[93] In November 2023, Teck divested its steelmaking coal unit by transferring assets to Elk Valley Resources (EVR), selling a 77% stake to Glencore for US$6.93 billion in cash and a 20% stake to Nippon Steel Corporation, retaining a 3% interest convertible to dividends.[39] [92] The deal, aimed at refocusing Teck on copper growth, received final Canadian regulatory approval on July 5, 2024, marking the end of Teck's direct operational oversight while ensuring continued production under new ownership.[64]Environmental Management and Sustainability
Water Quality and Pollution Controls
Teck Resources implements water stewardship practices centered on protecting downstream water quality through source controls, treatment technologies, and rigorous monitoring programs. The company's approach emphasizes adaptive management, structured around a six-step cycle that includes setting objectives, monitoring, evaluation, and adjustment based on empirical data from operations.[94] Source control measures prioritize designing mine waste facilities to inhibit acid rock drainage (ARD) and reduce contaminant leaching at the origin, aiming to minimize the need for downstream interventions.[95] In the Elk Valley steelmaking coal operations, where selenium and nitrate from geological sources pose primary challenges, Teck adheres to the Elk Valley Water Quality Plan (EVWQP), which establishes short-, medium-, and long-term targets protective of aquatic life and human health.[96] This includes constructing biological treatment facilities using processes like fluidized bed reactors for selenium removal and denitrification for nitrates, with operational plants achieving approximately 95% removal efficiency for both contaminants.[97] By February 2022, the third such facility was completed, contributing to a total treatment capacity of up to 12.5 million gallons per day across sites.[98] Extensive monitoring supports these controls, with Teck required to sample water quality at 155 locations in the Elk Valley and Koテンanusa Reservoir, generating data for annual reports prepared by independent scientists.[99] Compliance with regulatory directions, such as those under Canada's Fisheries Act, has driven additional mitigations, including expanded effluent treatment to address mine-related discharges.[100] Investments exceeding $1 billion have been allocated to these facilities and related infrastructure, with ongoing full-scale trials testing advanced removal technologies for scalability.[101][102]Biodiversity and Land Reclamation
Teck Resources manages biodiversity through the application of the mitigation hierarchy, which emphasizes avoiding impacts where possible, minimizing disturbances, rehabilitating affected areas, and offsetting residual effects.[103] All of its operating sites implement biodiversity management plans aligned with protocols from the International Council on Mining and Metals and Mining Association of Canada Towards Sustainable Mining.[103] The company commits to no exploration or mining in World Heritage sites and has adopted a net positive impact goal, aiming to halt and reverse biodiversity loss by 2030 in line with global frameworks.[103] A key target is to conserve or rehabilitate at least three hectares of land for every one hectare disturbed by operations, measured from a 2020 baseline, with all sites required to have net positive impact plans by the end of 2025.[104] As of 2023, prior to the divestiture of its steelmaking coal assets, Teck's total land footprint spanned 34,690 hectares, with 6,415 hectares reclaimed and 28,275 hectares pending reclamation; that year, 307 additional hectares were reclaimed across sites including Elk Valley, Quebrada Blanca, and Red Dog.[103] Following the 2024 sale of Elk Valley Resources, the adjusted footprint for remaining operations was 14,601 hectares, including 1,611 hectares reclaimed, with 17 hectares reclaimed on-site and 3 hectares restored off-site in 2024.[104] Cumulative off-site conservation and restoration since 2020 reached approximately 52,000 hectares by 2024, yielding a reported ratio exceeding 40:1 relative to 1,218 hectares disturbed in that period.[104] In the Elk Valley coal operations—divested in 2024—Teck advanced progressive reclamation using geomorphic landform design to mimic natural topography, revegetating over 800 hectares in 2021 alone as part of its largest rehabilitation initiative.[105] These efforts earned Teck the 2023 British Columbia Mine Reclamation Award in the coal category from the Technical and Research Committee on Reclamation for exemplary spoil management and ecosystem restoration at sites like Line Creek.[106] Post-divestiture, successor Elk Valley Resources received the 2024 award for West Line Creek rock spoil reclamation, building on Teck's foundational work.[107] At other sites, initiatives include Indigenous-led biodiversity assessments for the Highland Valley Copper extension, a Chilean conservation fund protecting ecosystems near Quebrada Blanca, and pilots for biochar soil enhancement at Red Dog to support revegetation in Arctic conditions.[104] Reclamation incorporates baseline ecosystem mapping and habitat suitability modeling to guide restoration toward pre-mining conditions, though long-term success depends on monitoring adaptive management.[103]Climate and Emissions Strategies
Teck Resources has established a climate strategy centered on reducing operational greenhouse gas (GHG) emissions through technological adoption and portfolio adjustments, with an ambition to reach net-zero Scope 1 and 2 emissions across its operations by 2050.[108] This approach emphasizes immediate emissions cuts via energy efficiency and low-carbon technologies, while advocating for policy frameworks like carbon pricing that prevent leakage and maintain competitiveness for trade-exposed industries.[109] The company's 2024 divestiture of steelmaking coal assets refocused its portfolio entirely on lower-intensity base metals production, such as copper and zinc, aligning with demand for materials essential to low-carbon transitions.[109] Key targets include achieving net-zero Scope 2 (purchased electricity) emissions by 2025 and reducing overall operational carbon intensity by 33% by 2030, measured against a 2020 baseline that was rebased following the coal asset sale in accordance with GHG Protocol guidelines.[110] For Scope 3 emissions, Teck aims for net-zero by 2050, with an interim goal of 40% reduction in shipping emission intensity by 2030.[110] Carbon offsets are capped at less than 10% of total reductions, limited to under 100,000 tonnes CO2e annually, prioritizing direct abatement over external credits.[110] Decarbonization efforts involve electrification of mobile equipment, adoption of renewable diesel and low-carbon fuels, and integration of renewables into power supply, achieving 82% renewable electricity usage in 2023 across operations.[109] Specific implementations include 100% renewable power at the Carmen de Andacollo copper mine and a power purchase agreement for Quebrada Blanca Phase 2 expected to avoid 1.6 million tonnes CO2e annually by 2025.[109] A carbon capture pilot at Trail Operations, launched in late 2023, captures 1 tonne of CO2 per day, with broader exploration of capture and storage technologies evaluated via marginal abatement cost analyses.[110] Teck collaborates with equipment manufacturers and participates in initiatives like the North Pacific Green Corridor to develop low-emission supply chains.[109] In 2023, Teck reported Scope 1 emissions of 863 kilotonnes CO2e (primarily from diesel at 453 kt and natural gas), Scope 2 market-based emissions of 611 kt CO2e, for a combined Scope 1+2 total of 1,474 kt CO2e, and Scope 3 emissions of 3,400 kt CO2e, with Category 10 (processing of sold products) comprising about 30% of the broader footprint.[109] Compared to 2022 figures of 881 kt CO2e for Scope 1+2 (pre-coal divestiture restatement), the company notes progress toward intensity targets, with copper operations ranking in the 36th percentile and zinc mining in the 20th percentile globally per independent benchmarks.[109] Challenges include rising carbon costs (28.6 million USD in 2023) and dependencies on emerging technologies like carbon capture, whose scalability remains unproven at industrial levels, though Teck's governance integrates climate risks into board-level oversight.[109]Controversies and Regulatory Challenges

Teck Resources' coal mining operations in the Elk Valley of British Columbia have been a primary source of selenium discharges since the expansion of open-pit mining in the region during the 1960s, with selenium leaching from waste rock piles exposed to rainfall and snowmelt, entering waterways such as the Fording, Elk, and Michel Rivers.[111] Selenium, a naturally occurring element mobilized by the oxidation of sulfide minerals in overburden, accumulates in aquatic ecosystems, where concentrations exceeding 2 micrograms per liter can impair fish reproduction by reducing larval survival rates and altering thyroid function in species like westslope cutthroat trout.[111] In the upper Fording River, selenium levels rose steadily from 2013 to 2020, reaching averages above regulatory limits in downstream segments, contributing to transboundary pollution flows into Lake Koocanusa and the Kootenai River in Montana and Idaho.[112] Regulatory scrutiny intensified in the 2010s after monitoring revealed non-compliance with British Columbia's Environmental Management Act and federal Fisheries Act effluent standards, prompting the 2014 Elk Valley Water Quality Plan, a collaborative framework between Teck, provincial authorities, and the Ktunaxa Nation aimed at stabilizing selenium trends through water treatment and enhanced monitoring.[96] In March 2021, Teck Coal Limited pleaded guilty to Fisheries Act violations for deleterious discharges of selenium and calcite into the Fording River, resulting in a $60 million penalty—the largest such fine in Canadian history—and a directive to implement specific reduction measures, including expanded treatment capacity.[112] Further penalties followed, including a $16 million administrative fine in February 2023 from British Columbia for delays in constructing water treatment facilities at Fording River operations, where selenium effluent limits were exceeded due to inadequate calcite scaling prevention.[113] Teck has invested over $1.2 billion by 2023 in mitigation, including biological treatment plants at Line Creek and Elkview mines that have reduced downstream selenium by up to 70% at those sites, alongside trials of sulfate-reducing bioreactor technology for nitrate and selenium removal.[114] [102] However, challenges persist, as selenium loading from legacy waste rock continues to elevate concentrations in untreated tributaries, with 2022 monitoring showing Fording River levels at 40-60 micrograms per liter near mine outflows, prompting additional federal charges in July 2024 for ongoing Fisheries Act breaches involving toxic substance releases into fish-bearing waters.[115] An August 2025 upholding of an $800,000 provincial penalty highlighted repeated weekly discharge limit violations at Elk Valley sites, occurring 80-85% of the time in 2017-2018.[116] These issues have raised human health concerns, with a 2024 British Columbia study indicating elevated selenium in locally harvested fish—up to five times grocery store equivalents—potentially posing risks for high-consumption diets among Indigenous communities.[117]Historical Contaminations
Teck Resources' Trail Operations, located in Trail, British Columbia, have been associated with significant historical contamination stemming from lead-zinc smelting activities that began in the early 20th century. For over five decades, from approximately the 1890s through the mid-20th century, the smelter discharged untreated slag—a byproduct laden with arsenic, mercury, lead, and other heavy metals—directly into the Columbia River, with daily volumes reaching up to 450 tons of toxic material.[118] [119] This practice contributed to widespread sediment contamination in the Upper Columbia River Basin, extending into the United States, where elevated levels of these metals persisted in riverbeds and floodplains.[120] [121] Aerial emissions from the smelter, particularly during the mid-20th century, dispersed lead particulates across surrounding areas, resulting in soil and vegetation contamination that affected local ecosystems and human health for nearly a century.[122] The 1938-1941 Trail Smelter arbitration between Canada and the United States addressed transboundary air pollution from sulfur dioxide and other emissions, establishing precedents for international environmental liability, though waterborne slag discharges continued unabated until regulatory changes in the 1990s.[123] By 2012, Teck acknowledged responsibility for these legacy discharges, leading to commitments for remediation under the Upper Columbia River Site cleanup efforts, including sediment capping and habitat restoration.[119] [121] In addition to riverine pollution, historical operations at Trail resulted in localized spills and emissions that contaminated nearby properties. For instance, in 2016, a spill of metal-laden wastewater occurred at the facility, lasting 15-20 minutes and prompting immediate containment measures, though it highlighted ongoing risks from legacy infrastructure.[124] In 2015, Teck entered an agreement with the U.S. Environmental Protection Agency to remediate lead-contaminated residential and allotment properties in northeastern Washington, addressing fallout from historical smelter emissions.[120] These incidents underscore the long-term persistence of contaminants from pre-regulatory era practices, with bioavailability studies indicating uptake into aquatic biota even decades later.[125]Legal and Compliance Actions
Teck Resources has faced multiple legal actions and compliance penalties primarily related to environmental violations at its mining operations. In March 2021, Teck Coal Limited pleaded guilty to two counts under Canada's Fisheries Act for unlawfully depositing selenium and calcite into Fording, Elk, and Coal creeks from its steelmaking coal mines in British Columbia's Elk Valley, resulting in a $60 million penalty—the largest fine ever under the Act at the time—comprising $15 million in fines and $45 million directed toward pollution reduction measures.[126][127] Subsequent enforcement included a $16.1 million administrative penalty imposed by British Columbia's Ministry of Environment in February 2023 for selenium exceedances and delays in constructing a water treatment plant at the Fording River Operations, marking one of the province's largest such penalties for mining pollution.[113] In January 2023, Teck Metals Ltd. was fined $2.2 million by a British Columbia provincial court for 27 counts of unauthorized effluent discharges into the Columbia River from its Trail Operations smelter between 2007 and 2019, violating the Metal and Diamond Surface Mining Effluent Regulations.[128] More recent proceedings encompass federal charges filed in July 2024 against Teck Coal for five Fisheries Act violations at its Line Creek Operations, alleging deleterious selenium discharges into Michel Creek and the Elk River watershed from 2019 to 2023, with potential penalties up to $6 million per count if convicted.[115] In August 2024, British Columbia levied an additional $220,500 administrative penalty on Teck Coal for 29 unauthorized waste discharges across its Elk Valley sites between 2021 and 2023.[129] Internationally, Teck Alaska Incorporated settled with the U.S. EPA in August 2024 for $429,000 over hazardous waste management violations at Red Dog Mine, including improper storage and disposal of lead-contaminated materials.[130] Ongoing litigation includes Pakootas v. Teck Metals Ltd., a CERCLA case stemming from historical smelter emissions contaminating the Upper Columbia River, where in February 2024 a federal court ruled that plaintiffs must adhere to specific natural resource damage assessment procedures, potentially limiting claims against Teck for cleanup and restoration costs.[131] In May 2023, U.S. environmental groups sought judicial review in Montana federal court challenging U.S. EPA approvals of selenium discharge permits for Teck's Elk Valley coal mines, arguing transboundary pollution into U.S. waters.[132] In Chile, the Superintendencia del Medio Ambiente filed charges in 2023 against Teck's Quebrada Blanca operations for non-compliance with water management requirements, risking fines up to $8 million.[133] These actions reflect regulatory scrutiny over Teck's wastewater treatment and pollutant controls, with the company often resolving matters through pleas or settlements while committing to enhanced mitigation.Economic Contributions and Community Engagement
Job Creation and Regional Development
Teck Resources' operations have historically supported substantial direct employment, with the company employing 12,100 workers globally as of December 2022, prior to the divestiture of its steelmaking coal assets.[134] Following the July 2024 sale of its Elk Valley steelmaking coal business to Glencore, Teck's workforce contracted to approximately 7,200 employees by December 2024, concentrated in copper, zinc, and energy segments across Canada, the United States, Chile, and Peru.[135] These direct roles span mining, processing, engineering, and support functions, with a focus on skilled trades, technical expertise, and operational safety training provided through in-house programs.[136] In resource-dependent regions like British Columbia's Elk Valley, Teck's steelmaking coal operations—prior to the 2024 transaction—generated significant multiplier effects, sustaining over 31,000 full-time equivalent jobs province-wide in 2022 through direct payroll, supplier contracts, and employee expenditures.[137] Locally, these activities accounted for nearly 47% of total employment in communities including Sparwood, Fernie, and Elkford, bolstering sectors such as transportation, retail, and services via induced economic activity.[138] The operations contributed $6.3 billion to British Columbia's gross domestic product that year, representing about 80% of the GDP in the broader Southeast region encompassing Cranbrook, Fernie, Sparwood, and Elkford.[139] Regional development extended beyond jobs through fiscal transfers and infrastructure support, with Teck's Elk Valley activities generating $1.5 billion in annual revenues to federal, provincial, and local governments in 2022 via taxes, royalties, and fees, funding public services and capital projects.[138] Community investments included workforce training initiatives, such as apprenticeships and skills programs tailored to local needs, which enhanced employability in mining-adjacent industries and mitigated boom-bust cycles.[140] In 2018, steelmaking coal operations alone drove $3.9 billion in total economic contributions to the Elk Valley, including employee wages and local procurement that stimulated business growth and housing development.[140] Post-divestiture, residual economic benefits persist through Teck's retained interests and ongoing copper-focused projects, though scaled to match operational shifts.[141]Indigenous Partnerships and Relations
Teck Resources maintains a formal Indigenous Peoples Policy that emphasizes building relationships through consultation, respect for rights and cultures, and sharing economic benefits from mining operations, with executive involvement in negotiations and grievance resolution.[142] The company reports 85 active agreements with Indigenous groups as of 2021, covering exploration, operations, and closure phases, including 10 new impact benefit agreements that year focused on revenue sharing, employment, and business opportunities.[143] Key partnerships include a 2017 participation agreement with the Fort McKay First Nation for the Frontier oil sands project, which outlined economic participation such as equity stakes and joint ventures.[144] Teck has procured goods and services from Indigenous suppliers as part of its commitment to local economic development, with engagement activities in 2019 involving 17 communities on agreement implementation, including business development topics.[145][146] Community investments directed toward Indigenous organizations totaled $2.8 million in 2021 across 96 groups, comprising 11.3% of Teck's overall spend.[143] Educational initiatives feature a partnership with Indspire since 2012, supporting First Nations, Inuit, and Métis students through scholarships and programs; this was extended via a three-year agreement announced on April 2, 2025, including $150,000 for the Building Brighter Futures program.[147] Internationally, Teck entered a US$1 million multi-year partnership with UN Women in 2016 to empower Indigenous women in northern Chile via skills training and economic opportunities.[148] Teck also integrates traditional knowledge from Indigenous groups into reclamation planning at sites like those in Canada.[149] Relations have faced strains, particularly amid Teck's proposed 2025 merger with Anglo American, which drew opposition from groups such as the Osoyoos Indian Band; they threatened legal and political challenges over potential impacts on Indigenous rights, title, and a planned copper smelter, demanding enforceable revenue-sharing and job commitments.[150][151] British Columbia First Nations leaders expressed concerns that the merged entity might dilute existing obligations to Indigenous communities.[152] These tensions highlight ongoing negotiations in resource development, where economic partnerships coexist with disputes over environmental and cultural effects.[153]Supply Chain and Global Impact
Teck Resources operates an integrated supply chain that spans procurement, production, and distribution for its primary commodities of copper, zinc, and steelmaking coal, with operations concentrated in Canada, the United States, Peru, and Chile. The company sources critical inputs such as heavy mobile equipment, machinery, fuels, lubricants, and explosives from international suppliers, implementing oversight mechanisms including supplier codes of conduct aligned with Teck's anti-bribery and corruption policies to mitigate risks like ethical lapses or supply disruptions.[154][155] These practices extend to value chain partners, requiring compliance with fundamental ethical principles to ensure operational integrity across global sourcing networks.[155] Distribution logistics rely heavily on rail transport and port facilities for exporting concentrates and metallurgical coal, with steelmaking coal shipments primarily directed to Asian markets for global steel production and zinc exports redirected toward Asia in response to U.S. tariffs implemented in early 2025.[156] Copper production from assets like Highland Valley Copper in Canada feeds into smelters worldwide, while potential U.S. tariffs on critical minerals are projected to have minimal effects due to Teck's diversified markets and domestic processing capabilities at facilities like Trail Operations.[157] As of October 2025, Teck's liquidity stood at $9.5 billion, bolstering supply chain resilience amid market volatility and enabling strategic adjustments to trade barriers.[11] On a global scale, Teck's output of approximately 300,000 tonnes of copper and 600,000 tonnes of zinc annually supports essential applications in electrification, renewable energy infrastructure, and defense technologies, reducing dependence on higher-risk suppliers like China amid export restrictions on rare earths and processed minerals.[2][158] The company's North American-centric assets position it favorably for supply security in allied nations, with ongoing discussions for direct mineral supplies to U.S. and Canadian defense sectors underscoring its role in geopolitical resource strategies.[159] This contributes to broader economic impacts, including billions in annual exports that underpin global manufacturing while exposing downstream industries to commodity price fluctuations driven by supply chain bottlenecks.[7]Recent Developments
Operational Reviews and Production Guidance
Teck Resources conducted a comprehensive operational review launched in August 2025 and completed on October 7, 2025, targeting performance enhancements at its Quebrada Blanca (QB) copper-molybdenum mine in Chile through a dedicated QB Action Plan that addressed tailings management facility (TMF) constraints, mill availability, and recovery rates. The review highlighted ongoing TMF development challenges, including the need to raise dam crest heights for safe, unconstrained production, while noting progress in sand plant improvements and geotechnical work. At Highland Valley Copper (HVC) in British Columbia, Canada, the assessment identified grade variability and sequencing issues contributing to lower-than-expected output. These findings led to adjusted mine plans emphasizing realistic recovery assumptions and operational efficiencies, with TMF expansion efforts continuing under regulatory oversight.[8][160] In its unaudited third-quarter 2025 results released on October 22, 2025, Teck reported QB copper production of 39,600 tonnes, a decline of 12,900 tonnes from Q3 2024, primarily due to TMF limitations restricting mill throughput. Zinc production at Red Dog mine in Alaska rose 14% quarter-over-quarter to 165,000 tonnes, supported by higher grades and improved mill utilization, while steelmaking coal output at Elk Valley Resources (post-divestiture) totaled 5.4 million tonnes amid weather-related disruptions. Overall, the quarter reflected resilient adjusted EBITDA of $860 million, up 19% from Q3 2024, driven by higher copper prices offsetting volume shortfalls.[7][11] Following the review, Teck revised its full-year 2025 production guidance downward for copper to 415,000–465,000 tonnes enterprise-wide, reflecting QB constraints and HVC grade challenges, a reduction of approximately 55,000–60,000 tonnes from prior estimates. Specific updates include QB copper at 170,000–190,000 tonnes and HVC copper at 120,000–130,000 tonnes, with molybdenum at QB projected at 3,000–3,500 tonnes. Zinc guidance remained at 525,000–575,000 tonnes, led by Red Dog, while steelmaking coal forecasts were adjusted to 22.0–23.0 million tonnes. Updated net cash unit costs for QB copper rose to $1.75–$2.00 per pound, incorporating higher sustaining capital of $940–$1,010 million. These projections assume zinc prices of US$1.27 per pound and molybdenum at US$22.50 per pound.[7][161]| Commodity/Mine | 2025 Production Guidance (tonnes) | Key Factors |
