1. Adex Mining (TSXV:ADE)

Weekly gain: 100 percent
Market cap: C$128.67 million
Share price: C$0.19

Adex Mining is an exploration company that holds a 100 percent stake in the Mount Pleasant project in Southwest New Brunswick, Canada. The property contains two main deposits: the Fire Tower zone, which hosts tungsten and molybdenum mineralization, and the North zone, which hosts tin, zinc and indium.

The asset consists of 102 mineral claims covering 1,600 hectares, as well as equipment and facilities from historic mining operations conducted by BHP (ASX:BHP,NYSE:BHP,LSE:BHP) between 1983 and 1985.

According to its most recent investor presentation released on June 11, the property hosts the world’s largest indium reserve and North America’s largest tin deposit. Indicated resources for the North zone demonstrate contained metal values of 47 million kilograms of tin, and 789,000 kilograms of indium from 12.4 million metric tons with average grades of 0.38 percent tin and 64 parts per million indium.

Adex Mining has not released news since it published its interim management discussion and analysis on November 18.

In a mid-February interview, New Brunswick Natural Resources Minister John Herron revealed that a deal “is due imminently with a well-known company in the Canadian mining community” for Adex’s Mount Pleasant project.

While the company did not release news this week, the project may benefit from the freshly announced New Brunswick Comprehensive Mineral Strategy. The report highlights Mount Pleasant’s indium, tin and tungsten mineralization.

2. Southern Energy (TSXV:SOU)

Weekly gain: 91.67 percent
Market cap: C$29.3 million
Share price: C$0.115

Southern Energy is an oil and gas company with assets located in Mississippi, US. The majority of its production is natural gas.

Its operations are centered around the state’s Interior Salt Basin, in the northeastern Gulf Coast Region. Southern has an interest in producing wells spread across several assets, including Gwinville, Mechanicsburg and Mount Olive East.

According to a February 2026 corporate presentation, current production from the company’s wells is about 11 million cubic feet of natural gas equivalent per day, with 27.9 million barrels of oil equivalent in reserves.

The company’s most recent news came on February 12, when Southern closed a non-brokered private placement that generated proceeds of US$23.5 million. The company said the funds will be used to repay the balance of a US$12.9 million senior credit facility, with the rest being directed to development capital, including the completion of two wells in Gwinville.

The share price gains also come amid volatility in the energy market.

3. Africa Energy (TSXV:AFE)

Weekly gain: 86.67 percent
Market cap: C$165.31 million
Share price: C$0.42

Africa Energy is a South Africa focused oil and gas exploration and development company.

Its flagship asset is Block 11B/12B located approximately 175 kilometers off the south coast of South Africa. The block covers an area of 18,734 square kilometers and depths between 200 meters and 1,800 meters.

It holds a 4.9 percent interest in the asset through its investment in Main Street 1549, a 49/51 joint venture with Arostyle Investments. The three other partners in the asset announced plans to withdraw from the Block 11B/12B joint venture in July 2024, and announced a definitive agreement for the new ownership structure of the Block 11B/12B asset in May 2025.

The restructuring would result in Africa Energy owning a direct 75 percent stake in the block, with Arostyle holding the remainder. This is contingent on the asset being granted the production rights, which itself requires approval of its environmental and social impact assessment. The report must be submitted by May 2026.

Shares of Africa Energy posted gains this week amid energy market volatility.

The company has not released any news since January 26, when it announced the resignation of Dr. Phindile Masangane as Director and Head of Strategy and Business Development. She will still assist Africa Energy as a consultant.

4. Gabriel Resources (TSXV:GBU)

Weekly gain: 60 percent
Market cap: C$41.58 million
Share price: C$0.16

Gabriel Resources is a precious metals explorer and developer focused on advancing its Rosia Montana gold project. Based in Transylvania, Romania, Rosia Montana is in a region that has seen significant historic mining. Covering 2,388 hectares, the site is host to a mid-to-shallow epithermal system containing deposits of gold and silver.

The most recent resource estimate from a 2012 technical report shows proven and probable quantities of 10.1 million ounces of gold and 47.6 million ounces of silver. Gabriel has invested more than US$760 million into Rosia Montana, but has undertaken little development at the site since the early 2010s, as Romania blocked further development.

In 2015, the company entered into arbitration through the World Bank’s International Center for Settlement of Investment Disputes (ICSID) over permitting at the site and suggested that Romania was in violation of bilateral investment treaties. In March 2024, Gabriel issued a press release with an update saying that its case against Romania had been dismissed by the ICSID, which also awarded Romania US$10 million in legal fees and expenses. Gabriel said it would review the decision with its legal team and evaluate its options.

In March 2025, Gabriel announced that the committee had ruled that a stay of enforcement of the Award would continue if Gabriel guaranteed the proven solvency of the US$10 million.

The committee was scheduled to hold hearings on January 22 and 23 of this year, but on January 19, Gabriel reported that the hearings would be postponed to a later date. A new date for the hearing has not been announced.

The company did not release news in the past week.

5. Rio Silver (TSXV:RYO)

Weekly gain: 48.05 percent
Market cap: C$41.58 million
Share price: C$1.14

Rio Silver is an exploration company advancing its Maria Norte project in Peru. The property changed hands several times in the 18 years prior to Rio Silver’s acquisition in March 2025, but saw little exploration during that time.

However, in a February 5 release, the company noted that historic mining occurred as the site hosts a reclaimed waste dump. In that announcement, the firm said it plans to advance surface mapping and sampling in the third quarter of 2026.

Throughout January, Rio Silver made several announcements regarding its exploration and development timeline. On January 6, the company reported results from technical work at the site, confirming the presence of silver mineralization with grades up to 991 g/t in a 0.7 meter channel sample.

To end the month, the company said it was launching a metallurgical program at the site to assist in determining the project’s potential value.

The most recent news came last week in a pair of releases.

The first on February 25, the company announced a new private placement to raise proceeds of up to C$3 million. Funds will be used to advance work at the Maria Norte project. The placement is being led by Sprott (TSX:SII,NYSE:SII) Founder Eric Sprott.

The second release came on February 26 when Rio reported it secured permission from the local community to begin site activities at Maria Norte. The company said it will continue working with the community to develop a formal definitive agreement for long-term exploration and mining activities.

FAQs for Canadian mining stocks

How much does it cost to list on the TSXV?

There are a variety of different fees that companies must pay to list on the TSXV, and according to the exchange, they can vary based on the transaction’s nature and complexity. The listing fee alone will most likely cost between C$10,000 to C$70,000. Accounting and auditing fees could rack up between C$25,000 and C$100,000, while legal fees are expected to be over C$75,000 and an underwriters’ commission may hit up to 12 percent.

The exchange lists a handful of other fees and expenses companies can expect, including but not limited to security commission and transfer agency fees, investor relations costs and director and officer liability insurance.

These are all just for the initial listing, of course. There are ongoing expenses once companies are trading, such as sustaining fees and additional listing fees, plus the costs associated with filing regular reports.

How do you trade on the TSXV?

Investors can trade on the TSXV the way they would trade stocks on any exchange. This means they can use a stock broker or an individual investment account to buy and sell shares of TSXV-listed companies during the exchange’s trading hours.

Platinum investment strength offsets softer overall demand

The forecast marks a shift from earlier expectations that the platinum market would return to balance in 2026.

Instead, strong investment sentiment and resilient exchange-traded fund holdings have pushed the market back into deficit territory. Even so, total demand for platinum is expected to decline moderately this year.

The WPIC projects overall demand will fall about 8 percent year-on-year to roughly 7.619 million ounces.

Much of that drop reflects a normalization in investment demand after a surge in 2025, when inflows into platinum exchange-traded funds and physical investment products climbed sharply.

However, demand for physical platinum bars and coins is expected to continue growing.

The WPIC forecasts that bar and coin investment will jump 35 percent in 2026 to 725,000 ounces, reaching the highest level recorded in the Platinum Quarterly dataset.

Investment purchases of platinum are increasing as the metal gains attention as a lower-priced alternative to gold, and as retail investment products become more widely available.

Supply growth lags as platinum deficit persists

While demand patterns shift across sectors, platinum supply growth remains limited.

Total platinum supply is expected to rise just 2 percent in 2026 to about 7.379 million ounces.

Mine output is forecast to remain essentially flat at roughly 5.553 million ounces, with production gains in South Africa and Zimbabwe offset by declines in North America and Russia.

The modest increase in supply will largely come from recycling. Higher platinum prices have encouraged the recovery of spent autocatalysts and recycled jewelry, pushing recycling supply up about 10 percent in 2025. That trend is expected to continue this year, with recycled metal rising another 10 percent to approximately 1.827 million ounces.

Still, the additional recycled material is unlikely to fully offset the underlying market tightness. As Raymond noted, another factor that could further deepen the deficit has yet to be fully reflected in current forecasts.

“One item not yet captured in the supply/demand balance is any exchange stocks warehoused with the Guangzhou Futures Exchange, which could potentially deepen the deficit versus current projections once these are made publicly available,” he said. For platinum investors, the persistence of deficits suggests that the market’s underlying fundamentals remain supportive even as demand moderates from last year’s highs.

“The price rally we’ve seen this year has not solved the deficit,” he said.

“Normally, in a deficit market, you would expect the price to increase. Clearly, the elevated prices we’ve experienced is still insufficient to attract more supply into the market or drag more metal out of aboveground stocks.”

With supply growth limited and inventories shrinking, the platinum market is likely to remain structurally tight, sustaining investor interest through 2026.

Addressing data fragmentation in exploration

Once companies open up capital expenditures to the exploration side of the mining sector, several questions arise, most notably: Where are the minerals?

At its core, exploration relies on the geosciences, with a geologist in the field, sampling rocks, conducting surveys and using the data gathered to estimate where the best place is to put a drill for a look below the surface.

Mining is a data-driven enterprise, and depending on the project, the information can come from a range of methods, from modern techniques to historic observations, meaning the data is fragmented across a variety of sources and formats.

AI and machine learning can be good at processing and interpolating large quantities of information. However, data accessibility creates another roadblock.

“Across our industry, vast volumes of exploration data are sealed in archive rooms, and legacy systems can’t read through third-party data sets,” Tepponen said. “That data is neither structured, searchable nor interoperable. That means AI cannot make easy sense of it, and in many cases, that data was never extracted.”

For Tepponen, one of the challenges the mining industry needs to overcome is data fragmentation. Without enough data or proper information, there is an increased risk of making the wrong exploration decisions.

“Time matters because capital is finite. Drill meters are expensive, and decisions about capital allocation have multi-year impacts down the line,” he said.

The way BHP has implemented a data-centric approach is building a central data platform that integrates the decades of exploration data, standardizes it and makes it accessible through a central team within the company.

Tepponen says the platform supports 52 standardized core geoscience types, backed by more than 100 years of data, helping its exploration teams save months of time.

“Our geoscientists can access more than 4 million drill hole cores and 9,000 geophysical surveys through one portal,” he added.

Using BHP’s in-house AI extraction tool, one team of geoscientists obtained data from thousands of drill holes from 30,000 legacy document records. They then used the central data platform to combine that with modern drilling data.

According to Tepponen, the team completed the work in a few hours, while doing so manually would have taken months, and results were higher quality than the previous method.

However, he stressed that the integration of AI into its workflow wasn’t about replacing geoscience teams, but about “amplifying the work of geoscientists by creating a digital tool that enables them to focus on higher value.”

Additionally, the information in the platform is not limited to BHP’s data. Tepponen explained that the entire system is built on an open-source database designed to break down data silos and enable cross-sector collaboration.

Using targeted optimizations to avoid disruptions

While exploration poses a bottleneck to the development of new projects for future supply, disruptions to existing operations significantly impact current output.

It’s often impossible to predict major events like extreme weather, civil unrest or regulatory changes. However, operators can foresee some disruptions that result in hundreds of hours of downtime throughout the industry every year.

Tepponen outlined one persistent problem: oversized rocks and foreign objects making their way through processing plants.

“If an uncrushable rock or piece of metal gets into the crusher, it can cause blockages, damage belts and create significant downtime,” he said. “If it travels downstream, it can damage equipment and create critical bottlenecks.”

In Western Australia, BHP employs a hub-and-spoke model that connects five mines to a central processing facility. If one of the hazards disrupts operations at the facility, it can affect operations at the mines connected to it.

Additionally, fixing these issues exposes maintenance teams to higher-risk tasks, so eliminating the problem in the first place improves both productivity and safety.

Tepponen explained that historically, workers would be used to identify the hazards before they were loaded onto the truck, but once they reached the conveyor, they became much harder to remove.

The company now employs a real-time monitoring system that detects objects, alerts controllers and can automatically stop the conveyor.

“These are actually very simple technologies available commercially off the shelf. Cameras and machine learning control systems applied to a real world operational constraint,” he said.

In the prior three years, these incidents had caused over 1,000 hours of downtime, according to Tepponen. However, since it installed the monitoring system, the company hasn’t experienced any major disruptions or destruction events caused by oversized rocks, a change that he said amounts to hundreds of thousands of metric tons per year of increased processing.

“It’s a small system-level optimization that can deliver outsized returns on the AI journey. This is not a massive program. This is identifying simple constraints, applying proven technology,” he said, and emphasized the process of controlled testing, iteration and then deploying at scale. ‘That’s how systematic innovation actually happens.’

Testing scenarios with digital twin simulations

In his third use case example, he turned to BHP’s semi-autogenous grinding (SAG) mill at its Escondida operation in Chile, at which differing particle size and hardness in ore feed was impacting production.

The company used AI to create a digital twin of the value chain, which included everything that was known about the operation, such as ore body knowledge, processing behavior and operational constraints.

“That digital simulation enabled scenario testing and gave us the ability to inform blasting and blending strategies to predict granularity,” Tepponen said, noting that monthly production losses attributed to the problem fell by around 70 percent.

“The lesson, when the ore body knowledge is connected directly to the processing decisions, the system becomes more stable and predictable.”

BHP has since applied the approach to other operations, including ones in Australia and Chile.

“The Gen AI integration is multicultural, so non-technical users and the technical users can run scenarios in their first language,” he said, an aspect that he said is very important for the local companies at its operations.

Building foundations, collaboration key to AI usefulness

Tepponen was emphatic that AI alone wasn’t a “superhero.” BHP needed to specifically design these AI platforms in order to achieve these results.

“One of the most important lessons we have learned is we don’t actually get value from AI by starting with AI. The value comes from the foundations, consistent data standards, interoperability. You need to start at the bottom and make your way to the top.”

Tepponen also stressed the value of collaboration, noting that companies tend to be protective of their intellectual property, but opportunities are being missed that could be mutually beneficial.

“The hard truth is, no company can solve this problem of data fragmentation and system integration,” he said, and the industry would benefit from a collaborative approach on standards, interoperability and data throughout the value chain.
