5 Best-performing Copper Stocks on the TSX in 2025

1. Trilogy Metals (TSX:TMQ)

Year-to-date gain: 602.37 percent
Market cap: C$2.42 billion
Share price: C$11.87

Trilogy Metals is a polymetallic exploration and development company working to advance its Upper Kobuk mineral projects in Northern Alaska, US, which it owns in a 50/50 joint venture with South32 (ASX:S32,OTC Pink:SHTLF).

Its most advanced asset is the Arctic copper, zinc, lead, gold and silver project, which is in the feasibility stage. In an updated feasibility study from February 2023, the company reported annual payable production volumes 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, the study pegged the net present value at US$1.11 billion, with an internal rate of return of 22.8 percent and a payback period of 3.1 years.

Trilogy’s other key asset is the Bornite copper-cobalt project located 25 kilometers southwest of its Arctic project. The site hosts widespread mineralization and has seen historic exploration dating back to the 1950s.

A preliminary economic assessment for Bornite, dated January 15, established an after-tax net present value of US$393.9 million, with an internal rate of return of 20 percent and a payback period of 4.4 years. The updated mineral resource included with the report estimates an inferred resource of 6.53 billion pounds of copper with an average grade of 1.42 percent from 208.9 million metric tons of ore.

Trilogy’s Upper Kobuk assets are among the mineral projects dependent on the approval and construction of the Ambler Access Road, a planned 211 kilometer industrial road through Alaska.

Trilogy’s share price saw substantial gains in October after the US Senate repealed a land management plan that prevented the construction of the access road due to environmental concerns, and the current US administration supported its construction.

Additionally, Trilogy reported on October 6 that it had entered into a binding letter of intent that would see the US Department of Defense (DoD) invest US$17.8 million in Trilogy in exchange for 8.22 million Trilogy shares, or 10 percent of the company. The DoD would also hold warrants for an additional 7.5 percent, exercisable only after the road is constructed.

The funds are earmarked for exploration and development of the Upper Kobuk projects.

According to the release, the DoD will work to facilitate financing for the road’s construction and collaborate with Trilogy to expedite mine permitting using the FAST-41 process.

Shares in Trilogy reached a year-to-date high of C$14.70 on October 14.

2. St. Augustine Gold and Copper (TSX:SAU)

Shares in St. Augustine Gold and Copper reached a year-to-date high of C$0.58 on July 28.

3. Northern Dynasty Minerals (TSX:NDM)

Year-to-date gain: 337.65 percent
Market cap: C$2.15 billion
Share price: C$3.72

Northern Dynasty Minerals is an exploration and development company focused on the Pebble project, a copper-molybdenum-gold-silver project located 200 miles southwest of Anchorage in the Bristol Bay region of Alaska.

Pebble, which the company says is “one of the greatest stores of mineral wealth ever discovered,” hosts a measured and indicated copper resource of 6.5 billion metric tons and an inferred copper resource of 4.5 billion metric tons.

The Pebble property’s measured and indicated resources for molybdenum, gold and silver total 1.26 million metric tons, 53.82 million ounces and 249.3 million ounces, respectively.

The project stalled in 2020 during the permitting phase following a US Environmental Protection Agency (EPA) veto that suggested the proposed mine would damage the Bristol Bay watershed.

Early in 2024, the Supreme Court declined to hear the matter on procedural grounds, sending it back to the federal district court and the federal circuit of appeals before the Supreme Court would hear it.

Northern Dynasty spent the rest of 2024 advancing its case in Alaska’s state court. In March of that year, it announced the filing of actions to vacate the EPA’s veto.

In 2025, shares of Northern Dynasty began to surge following Trump’s March 20 executive order that called for expedited approvals for domestic mineral production and included copper as a strategically important mineral.

Since Trump became president, Northern Dynasty has been attempting to work with the EPA to vacate the veto on the project. On February 18, the company agreed to grant the EPA a requested 90 day extension to allow for review by the new leadership in the agency, and granted a further 30 day extension on May 14 and a 20 day extension on June 12.

Although the company had hoped to reach a settlement in early July, it ultimately was forced to file a motion for summary judgment on July 17 to have the EPA veto removed.

The most recent update came on October 8, when Northern Dynasty reported that it had filed a brief with the court and presented arguments as to why the veto should be removed. The company’s president and CEO stated in the release that he believes the company has a strong case.

Shares in Northern Dynasty reached a year-to-date high of C$3.89 on October 14.

4. Imperial Metals (TSX:III)

Year-to-date gain: 251.63 percent
Market cap: C$1.17 billion
Share price: C$6.47

Imperial Metals is a mine development and production company with operations in British Columbia, Canada.

It holds a 30 percent interest in the Red Chris mine in BC’s Golden Triangle, with the remainder owned by Newmont (TSX:NGT,NYSE:NEM,ASX:NEM). Imperial also fully owns the Mount Polley copper-gold mine, which reopened in June 2022, and the Huckleberry copper mine, which has been under care and maintenance since 2016.

Provincial approvals of a 4 meter raise of the embankment at its Mount Polley tailings storage facility has been the subject of an ongoing lawsuit this year after the Xatśūll First Nation applied for an interim injunction challenging them in April.

A June 30 update reported that the BC Supreme Court reserved judgment on the case following a four-day hearing.

The Supreme Court ultimately dismissed the Xatśūll First Nation’s application for the injunction and judicial review of the approvals on August 6.

Imperials’ most recent update on the case came on September 3, when the Xatśūll First Nation filed a notice of appeal to overturn the dismissal of the judicial reviews. However, they did not appeal the injunction decision, meaning the company can complete the raise and continue mining at Mount Polley.

In an exploration update at the mine on August 12, Imperial reported the discovery of copper mineralization in a 400 meter blind target step-out hole located 4 kilometers from the mill site. The hole showed significant visual native copper, with one intercept returning 0.7 percent copper over 7 meters and another returning a grade of 0.25 percent copper over 20 meters.

The company stated that the results were significant because the hole is 390 meters away from the nearest known mineralized zone and the hole is unique in the prominence of native copper, raising the possibility of other similar-style mineralization in the area.

On August 29, Imperial announced that it received approval for a permit amendment allowing the company to expand Mount Polley’s operations and extend its operating life, including pit development and expansion of storage areas within the existing mine site footprint.

Shares in Imperial reached a year-to-date high of C$6.75 on October 2.
