Top-Performing Copper Stocks List: TSX Leaders in 2025

The copper market experienced considerable price swings throughout 2025, shaped by competing economic forces and structural supply-demand dynamics. Global recessionary pressures and tariff uncertainty created volatility, yet the year concluded with prices finding support as market participants recognized an emerging supply deficit looming in 2026. Major production disruptions intensified these market conditions—critical operations at two of the world’s premier mining assets, Ivanhoe Mines’ Kamoa-Kakula and Freeport-McMoRan’s Grasberg, faced unexpected shutdowns triggered by seismic activity and material ingress incidents respectively. Simultaneously, demand for this essential base metal accelerated, propelled by AI infrastructure buildout and the global energy transition. This backdrop has created exceptional opportunities within the copper stocks list, particularly among TSX-listed mining companies. Below is a comprehensive analysis of the five most formidable copper stocks list performers on the Toronto Exchange, based on 2025 calendar-year price appreciation data compiled through December 9, 2025. The screening methodology focused on companies exceeding C$50 million in market capitalization, offering a view into the sector’s most compelling equity opportunities.

Imperial Metals: BC-Based Producer Delivers Strongest Gains in Copper Stocks List

Imperial Metals (TSX:III) achieved extraordinary performance, with shares advancing 333.7 percent over the 2025 calendar year. The company trades at C$7.98 with a market capitalization of C$1.4 billion, ranking as one of the year’s standout copper stocks list entries.

The company operates as a mine development and production entity with assets concentrated in British Columbia’s renowned mining jurisdictions. Its crown jewel, a 30 percent stake in the Red Chris mine situated within BC’s Golden Triangle, positions the company at the forefront of copper production. Newmont holds the complementary stake in this joint venture. Imperial’s fully owned asset portfolio includes the Mount Polley copper-gold operation, which resumed production in June 2022 following a multiyear hiatus, and the Huckleberry copper mine, placed on care and maintenance status since 2016.

Operational momentum accelerated substantially in 2025. Red Chris delivered impressive copper output—Q3 production reached 20.9 million pounds, representing a 10 percent year-over-year increase from 18.98 million pounds recorded in the prior-year quarter. For the nine-month period spanning January through September, production climbed even more dramatically, surging 20 percent to 67.51 million pounds versus 56.37 million pounds during the equivalent 2024 interval.

The Mount Polley expansion project advanced through a critical permitting hurdle on August 29, when the company secured approval for an amendment extending the mine’s operational life and expanding storage infrastructure. This approval enables pit development and enhanced operational scope within the existing mine boundary. The expansion initiative remained subject to ongoing judicial proceedings after the Xatśūll First Nation pursued injunction relief in April. However, the BC Supreme Court delivered a decisive judgment on August 6, dismissing the First Nation’s application for injunction and judicial review. Although the appellants subsequently filed an appeal notice on September 3, they did not contest the injunction dismissal, permitting Mount Polley operations to proceed unimpeded.

The Huckleberry asset demonstrated exploration potential through November activities, with the company releasing assay results from its 2025 drilling program. Notable intervals included 0.5 percent copper over 52.7 meters, with a high-grade sub-interval returning 0.81 percent copper and 0.23 g/t gold across 22.6 meters.

Meridian Mining: Brazilian Copper Development Stock Rises 313 Percent

Meridian Mining (TSX:MNO) emerged as the second-strongest performer within the copper stocks list universe, recording year-to-date appreciation of 313.33 percent. The equity trades at C$1.55 with an aggregate market value of C$656.72 million.

The company is advancing the Cabaçal copper-gold project in Brazil’s Mato Grosso state—a development-stage copper stocks list asset featuring an 11-kilometer mineralized corridor within a 50 square-kilometer license package. The project demonstrates compelling economics grounded in a prefeasibility study released March 10. That assessment outlined a post-tax net present value of US$984 million, assuming an internal rate of return of 61 percent and a capital recovery period of merely 17 months. The resource base encompasses 204,470 metric tons of contained copper from 51.43 million metric tons of ore averaging 0.4 percent grade. Mine life projections span 10.6 years with total lifecycle copper output reaching 169,647 metric tons, alongside meaningful silver and gold endowments.

Development activities accelerated through 2025, with the company engaging Ausenco Brazil as the lead engineering consultant to produce a definitive feasibility study targeted for completion in the first half of 2026. The extensive exploration program yielded encouraging results announced on October 7, featuring robust assay intervals of 1.4 percent copper equivalent over 27.5 meters, including a sub-interval of 6.1 percent copper equivalent over 6.4 meters. These grades of copper, gold, and silver mineralization are anticipated to support resource and reserve upgrades in the pending definitive study.

A pivotal regulatory milestone occurred on November 3, when the State of Mato Grosso formally granted preliminary licensing approval for Cabaçal—the first of three governmental authorizations required before mine commissioning. Meridian’s focus now shifts toward obtaining installation licensing, which would unlock the construction phase. The share price reached its year-high of C$1.65 on December 4, reflecting investor confidence in the project’s trajectory.

St. Augustine Gold and Copper: Philippines-Focused Developer Achieves 300 Percent Appreciation

St. Augustine Gold and Copper (TSX:SAU) constitutes the third-ranked copper stocks list component, delivering precisely 300 percent price appreciation through year-end. Shares command C$0.32 with a corresponding C$331.75 million market capitalization.

The company concentrates development efforts on the King-king copper-gold project spanning the Davao de Oro province in the Philippines, encompassing 184 mining claims. A pivotal corporate transaction closed on May 30, establishing definitive ownership dynamics. Under this restructuring, St. Augustine acquired 100 percent of Nadecor’s milling subsidiary—Kingking Milling—which holds development rights to the King-king project. Consideration included C$9.02 million in cash supplemented by 185 million shares issued to Nadecor. Exploration and development permit stewardship remains with Kingking Mining, sustained as a 40/40/20 trilateral partnership among St. Augustine, Nadecor, and Queensberry Mining and Development.

Subsequently, on June 18, the company executed a debt-to-equity conversion with Queensberry Mining, transforming C$1.67 million in outstanding obligations into 25.31 million St. Augustine common shares at C$0.066 per unit. This transaction elevated Queensberry’s ownership stake to 52 percent of total issued and outstanding equity.

The project’s updated feasibility study, released July 31, anchored assumptions on US$4.30 per pound copper and US$2,150 per ounce gold pricing. The resulting economics yielded an after-tax net present value of US$4.18 billion, reflecting an internal rate of return of 34.2 percent and payback within 1.9 years. Development spans six sequential phases, with average production over the opening five-year period estimated at 129,000 metric tons of copper and 330,000 ounces of gold annually. The full 31-year mine life projects average annual production of 96,411 metric tons of payable copper and 185,828 ounces of gold.

Optimization activities progressed through engagement with Stantec Consulting and Independent Mining Consultants on October 8 to produce an enhanced definitive feasibility study. The revised assessment prioritizes improvements including a chloride leach processing approach for low-grade sulfide stockpile recovery and increased throughput capacity. The stock achieved its year-high of C$0.58 on July 29, subsequently moderating as December concluded.

Trilogy Metals: Alaskan Polymetallic Developer Gains 269 Percent

Trilogy Metals (TSX:TMQ) occupies the fourth position among 2025’s copper stocks list champions, with shares appreciating 269.23 percent through year-end. The company trades at C$6.24 valuing the enterprise at C$1.07 billion market capitalization.

Trilogy operates as a polymetallic exploration and development firm advancing Arctic and Bornite projects within Alaska’s Upper Kobuk mineral district. The company maintains a 50/50 partnership with South32 in these assets. The flagship Arctic project, progressing through feasibility evaluation, encompasses copper, zinc, lead, gold, and silver mineralization. A February 2023 feasibility study projected annual payable production of 148.68 million pounds of copper, 172.6 million pounds of zinc, 25.75 million pounds of lead, 32,538 ounces of gold, and 2.77 million ounces of silver. After-tax economics derived a net present value of US$1.11 billion with a 22.8 percent internal rate of return and 3.1-year payback timeline.

The secondary asset, the Bornite copper-cobalt project situated 25 kilometers southwest of Arctic, hosts extensive mineralization with exploration heritage extending to the 1950s. A January 15 preliminary economic assessment established after-tax net present value of US$393.9 million, an internal rate of return of 20 percent, and 4.4-year payback. The resource base encompasses 6.53 billion pounds of copper at an average 1.42 percent grade from 208.9 million metric tons of ore.

Both projects remain contingent upon the Ambler Access Road authorization and construction—a 211-kilometer industrial corridor through Alaska designed to unlock development potential. Substantial momentum emerged during October 2025 following US Senate action to repeal prior land management restrictions that previously blocked access road construction on environmental grounds.

Policy support intensified further when the US Department of Defense agreed on October 6 to deploy US$17.8 million into Trilogy equity in exchange for 8.22 million shares—representing 10 percent ownership. Concurrently, the DoD secured warrants for an additional 7.5 percent exercisable upon access road completion. These funds specifically target exploration and development activities across the Upper Kobuk assets. According to the DoD commitment, the agency will facilitate financing arrangements for access road construction and collaborate with Trilogy to expedite mine permitting via the FAST-41 federal authorization process.

On October 24, the Alaska Industrial Development and Export Authority executed right-of-way permits with the US Army Corps of Engineers, National Parks Service, and Bureau of Land Management, formally reestablishing federal authorizations necessary for project advancement. The share price reached its annual peak of C$14.70 on October 14, representing a substantial pullback from the October highs by year-end closure.

Northern Dynasty Minerals: Pebble Project Stock Advances 234 Percent

Northern Dynasty Minerals (TSX:NDM) ranks fifth within the copper stocks list performance hierarchy, recording 234.12 percent year-to-date appreciation. The company trades at C$2.84 per share with a C$1.53 billion market capitalization.

Northern Dynasty concentrates development focus on Pebble, a copper-molybdenum-gold-silver project occupying 200 miles southwest of Anchorage in Alaska’s Bristol Bay region. The company describes Pebble as “one of the greatest stores of mineral wealth ever discovered.” The deposit hosts measured and indicated copper resources of 6.5 billion metric tons supplemented by inferred copper resources of 4.5 billion metric tons. Associated molybdenum, gold, and silver resources total 1.26 million metric tons, 53.82 million ounces, and 249.3 million ounces, respectively.

The project encountered a significant regulatory impediment in 2020 when the Environmental Protection Agency issued a categorical veto during the permitting phase, citing anticipated Bristol Bay watershed damage concerns. Early 2024 witnessed the Supreme Court declining to hear the matter on procedural grounds, redirecting the case to federal district and circuit courts before potential Supreme Court consideration. Northern Dynasty advanced its legal strategy throughout 2024 via Alaska state court filings challenging the EPA veto, formally announcing such actions in March of that year.

The competitive landscape shifted dramatically during 2025. Following a March 20 executive order prioritizing expedited approvals for domestic mineral production and designating copper as strategically essential, Northern Dynasty commenced intensive engagement with EPA leadership regarding veto removal. The company negotiated multiple deadline extensions: a 90-day extension granted February 18, an additional 30 days granted May 14, and a further 20-day extension granted June 12. Although settlement discussions progressed, the company ultimately pursued a summary judgment motion on July 17 when early-July settlement negotiations proved unsuccessful.

The company’s legal strategy continued through the remainder of 2025. On October 8, Northern Dynasty reported having filed court briefs articulating the rationale for veto removal, with company leadership expressing confidence in case strength. A revised litigation timeline emerged November 19, acknowledging delays attributable to federal government operations disruption. Under this revised schedule, the Department of Justice must submit its opening brief by February 16, 2026, with plaintiffs’ responsive filings due April 15, 2026. Northern Dynasty characterized the January 2-to-April timeline extension as excessive and reiterated its preference for EPA veto withdrawal.

December 1 brought encouraging developments when the National Mining Association, American Exploration and Mining Association, Alaska Mining Association, and US Chamber of Commerce collectively filed amicus briefs supporting Northern Dynasty’s position. Their consolidated argument emphasized:

“This case is exceptionally important to Amicis members, the mining industry, and the nation’s economy. The proposed mine—which the US EPA has unlawfully vetoed—will provide a crucial source of copper for construction, transportation, electrical and electronic projects, industrial machinery, and defense applications.”

These third-party endorsements underscore copper’s strategic importance within the domestic economy. The share price achieved a year-high of C$3.89 on October 14 before moderating into year-end trading.
