Top 5 Junior Copper Stocks on the TSXV in 2026

1. Tintina Mines (TSXV:TTS)

Year-to-date gain: 446.67 percent
Market cap: C$271.44 million
Share price: C$2.05

Tintina Mines is advancing its flagship Domeyko Sulfuros copper-gold project in Chile. The site is located in the Atacama region of Northern Chile and comprises 75 mining concessions totaling 10,056 hectares.

On February 2, Tintina released a preliminary economic assessment for the property. The study outlines a pre-tax net present value of US$560 million, an internal rate of return of 15 percent and a payback period of eight years from a base-case copper price of US$4.30 and a gold price of US$2,500.

Its most recent news came on June 2 when the company announced it was opening a private placement to raise C$91 million in proceeds to advance work at Domeyko Sulfuros toward a final investment decision.

The offering will be anchored by an investment from a new investment vehicle, G Mining Capital, split between Sumitomo (OTC Pink:SSUMF,TSE:8053) and the family that founded G Mining Services.

It will also include participation from Franco-Nevada (TSX:FNV,NYSE:FNV).

Shares in Tintina reached a year-to-date high of C$2.15 on June 3.

2. Kingfisher Metals (TSXV:KFR)

Year-to-date gain: 338.46 percent
Market cap: C$143.56 million
Share price: C$1.15

Kingfisher Metals is an exploration company focused on its HWY 37 project in British Columbia, Canada. The property, located in BC’s Golden Triangle, covers 933 square kilometers and hosts several epithermal and porphyry copper and precious metals deposits, including Hank and Williams, which were identified during historical exploration of the site.

Kingfisher has been actively exploring the property in 2026, announcing on April 16 it identified the new Turquoise near-surface porphyry target within the Hank-Mary district, 6 kilometers from existing infrastructure at HWY 37.

“Turquoise represents a compelling new drill target that we’re excited to test this summer,” Kingfisher CEO Dustin Perry said.

Then on April 28, Kingfisher announced that initial results from geochronological studies confirmed that its porphyry mineralization across the Hank, Mary and Williams deposits was formed in the Early Jurassic period, between 190 million and 186 million years ago.

According to the company, it was one of the most fertile timespans for mineralization in BC, and the timing window overlaps with the formation of the Mitchell deposit at Seabridge Gold's (TSX:SEA,NYSE:SA) nearby KSM project.

In addition to exploration, Kingfisher has also focused on fundraising. On March 3, it closed a bought deal private placement for gross proceeds of C$30 million through a mix of flow-through and hard dollar shares.

The company said it will use the flow-through proceeds for qualifying exploration expenditures at its properties in BC, with the hard dollar funding planned for exploration and corporate expenses.

On May 6, Kingfisher reported that it was fully funded for its 2026 exploration program that would commence in mid-June and run until the fall season. It includes a 15,000 meter drill program focused on advancing the Hank system and de-risking the broader regional target pipeline, plus multiple surveys at both HWY 37 and the company's Forrest Kerr project.

After spiking in mid-January on the Williams news, Kingfisher hit a year-to-date high of C$1.39 on May 13.

3. Barksdale Resources (TSXV:BRO)

Year-to-date gain: 294.12 percent
Market cap: C$65.95 million
Share price: C$0.335

Barksdale Resources is a copper explorer focused on advancing its Sunnyside asset in Arizona, US. The property covers approximately 21 square kilometers south of Tucson. It hosts an intrusive complex that the firm believes to be an extension of the copper-zinc-lead-silver system found at South32's (ASX:S32,OTCPL:SOUHY) Taylor deposit.

In 2025, the company achieved several milestones under its earn-in agreement and completed the initial 51 percent in September following a C$1 million cash payment. Prior to the payment in June, Barksdale said it would work toward increasing its interest in the property to 67.5 percent.

On May 4, Barksdale provided results from the first four holes of its 2026 drill program at Sunnyside, testing the Triple C copper-silver target.

“The 2026 exploration program is focused on near surface copper and silver targets that can quickly add value to the portfolio,” CEO William Wulftange said.

One of the drill holes intersected 392.19 meters grading 0.45 percent copper from a depth of 3.05 meters, including 60.96 meters grading 0.9 percent copper from a depth of 173.74 meters and 60.96 meters grading 0.93 percent copper from a depth of 265.18 meters.

In its most recent update, on June 11, Barksdale shared it had completed 20,005 feet of drilling across 19 holes so far, and its current drilling was testing near-surface targets. Barksdale expects the program to be completed in early July, and is planning to follow it with a 50,000 foot Phase 2 drill program in fall 2026..

Additionally, the company said it is developing a plan to conduct an airborne survey of the property to define targets for a controlled-source magnetotellurics survey.

Shares of Barksdale Resources reached a year-to-date high of C$0.53 on May 20.

4. Panoro Minerals (TSXV:PML)

Year-to-date gain: 248.65 percent
Market cap: C$409.65 million
Share price: C$1.29

Panoro Minerals is a copper explorer focused on advancing its flagship Cotabambas copper-gold project in the Apurimac region of Southern Peru.

The property consists of two primary mineralized zones, and exploration on the property dates back to the mid-1990s and has largely focused on an 18-square-kilometer area in the northeast portion of the property.

According to the most recent mineral resource estimate, published in January 2024, Cotabambas hosts an indicated copper resource of 3.75 billion pounds of copper from 507.3 million metric tons of ore with an average grade of 0.33 percent, and an additional inferred resource of 2.96 billion pounds of copper from 496 million metric tons of ore with an average grade of 0.27 percent.

The company has been actively exploring the site in 2026, and commenced a 15,000 meter drill program in mid-April.

On June 8, Panoro released assay results for a drill hole encountered continuous mineralization over 850 meters. Starting at 414 meters downhole, the hole intersected a higher-grade 317.6 meter interval grading 0.46 percent copper, including intersections of 162 meters grading 0.65 percent copper and 66.1 meters 0.83 percent copper. Additional gold and silver mineralization raised copper equivalent results in the hole.

The company also stated that it encountered potassic alteration at depth, "potentially signaling drilling is approaching the porphyritic source of the South Pit deposit." Additionally, the company said it was expanding its drill program to 45,000 meters, adding 30,000 meters, and would conduct further drilling along strike.

“The results validate our thesis that the high-grade mineralization continues at depth, which should allow us to potentially expand resources at Cotabambas meaningfully,” President and CEO Luquman Shaheen said.

The company has also been working to secure funding throughout much of the first half of the year, raising C$4 million in February and completing an upsized private placement for gross proceeds of C$21 million on May 13.

Shares in Panoro reached a year-to-date high of C$1.46 on June 2.

5. Selkirk Copper (TSXV:SCMI)

Weekly gain: 191.38 percent
Market cap: C$155.07 million
Share price: C$1.69

Selkirk Copper Mines is a gold and copper exploration and development company working to advance the Minto mine project in the Yukon, Canada.

The property covers 26,850 hectares of mineral tenure centered around the past-producing Minto copper-gold-silver mine, which was abandoned in 2023.

The Selkirk First Nation, which holds a controlling interest in Selkirk Copper, became the first Indigenous nation in Canada to own a mine when it purchased Minto in early 2025.

Selkirk Copper released an updated mineral resource estimate for the project in July 2025, demonstrating a total indicated resource of 333.8 million pounds of copper, 186,600 ounces of gold and 1.73 million ounces of silver from 12.59 million metric tons of ore with average grades of 1.2 percent copper, 0.46 grams per metric ton (g/t) gold and 4.3 g/t silver.

Since the start of 2026, Selkirk has released several project updates.

On April 15, the company announced the completion of the Phase 1 drill program comprising 52,288 meters across 175 holes, one of the largest exploration programs in the Yukon over the past 10 years.

Additionally, the release states Selkirk assumed responsibility for all site operations on April 1 and was eyeing a potential restart of mining at the site in mid-2027.

Then on June 3, the company released the final assays from Phase 1 drilling, and shared that it had already drilled 14,000 meters of the 50,000 meter Phase 2 drill program. Selkirk said the focus of the new activities is on resource expansion, infill, geotechnical drilling and data collection.

Selkirk plans to complete an updated MRE and preliminary economic assessment in mid-2026 that will incorporate the Phase 1 results.

Regarding project funding, the company announced on April 30 that it had closed an upsized bought-deal private placement of C$35 million. Then, on May 25, the company reported that it had closed on a C$500,250 private placement from the Selkirk First Nation.

Selkirk said it intends to use the funds from both placements to continue development and restart activities at the mine.

Shares in Selkirk reached a year-to-date high of C$2.10 on May 13.
