Canada's Best Mining Stocks This Week: Adex Mining Leads With Over 100% Surge

This week’s market movements have spotlighted some exceptional performers among Canada’s best mining stocks, with exploration and development companies seeing substantial gains amid a volatile commodity environment. Adex Mining topped the rankings with a stunning 100 percent weekly surge, reflecting broader market enthusiasm for the resource sector driven by geopolitical tensions and supportive policy developments.

Market Tailwinds: Energy Crisis and Policy Support Boost Mining Sector

Two major factors converged to elevate Canadian mining stocks this week. The New Brunswick government unveiled its comprehensive mineral strategy on Tuesday, emphasizing streamlined permitting and transparent timelines for resource projects. The initiative also highlights collaborative engagement with First Nations and community-based development approaches—direct support for exploration companies like Adex Mining operating in the province.

Simultaneously, geopolitical tensions have reshaped commodity markets. Following escalating US-led military action, West Texas Intermediate crude surged more than 25 percent since March 1, breaching US$90 per barrel by Friday for the first time since October 2022. Oil price spikes of this magnitude historically correlate with increased exploration budgets and renewed investor interest in resource equities, benefiting the broader mining sector and energy-focused companies alike.

Commodity Markets Set the Stage for Top Performers

The broad commodity landscape showed mixed signals this week. While the S&P/TSX Composite Index declined 3.87 percent to close at 33,083.72 on Friday, March 6, and the S&P/TSX Venture Composite Index slipped 4.54 percent to 1,057.04, precious metals faced headwinds. Gold retreated 3.31 percent to US$5,170.63 per ounce, and silver dropped 6.4 percent to US$84.30. Copper also declined 2.01 percent to US$5.85 per pound. However, the CSE Composite Index gained 1.27 percent to 178.51, demonstrating resilience among smaller-cap companies where the best mining stocks often trade.

Five Best Mining Stocks in Canada This Week

1. Adex Mining: Indium and Tin Exploration Leader

Weekly Performance: +100 percent | Market Cap: C$128.67 million | Share Price: C$0.19

Adex Mining commands attention as this week’s standout performer among Canada’s best mining stocks. The exploration company holds a 100 percent stake in the Mount Pleasant project in Southwest New Brunswick, a property featuring the Fire Tower zone (tungsten and molybdenum) and the North zone (tin, zinc, and indium mineralization). The company operates 102 mineral claims spanning 1,600 hectares, including historic mining infrastructure from BHP’s 1983-1985 operations.

The Mount Pleasant project hosts the world’s largest indium reserve and North America’s largest tin deposit. Current resource estimates indicate 47 million kilograms of tin and 789,000 kilograms of indium contained in 12.4 million metric tons at average grades of 0.38 percent tin and 64 parts per million indium. A mid-February interview with New Brunswick Natural Resources Minister John Herron suggested a partnership “is due imminently with a well-known company in the Canadian mining community.” The newly announced provincial mineral strategy specifically highlights Mount Pleasant’s strategic mineralization, reinforcing the company’s positioning.

2. Southern Energy: Natural Gas Producer Capitalizes on Energy Rally

Weekly Performance: +91.67 percent | Market Cap: C$29.3 million | Share Price: C$0.115

Southern Energy represents the second-strongest performer among best mining stocks this week, though the company focuses on oil and gas assets in Mississippi’s Interior Salt Basin. Current production reaches approximately 11 million cubic feet of natural gas equivalent per day, supported by 27.9 million barrels of oil equivalent in proven reserves. The company closed a non-brokered private placement on February 12 that raised US$23.5 million, earmarked for debt repayment and development capital, including completion of two Gwinville wells.

The sharp gains reflect broader energy sector strength following crude price acceleration, demonstrating how commodity cycles influence publicly traded resource companies.

3. Africa Energy: South Africa Exploration on Restructuring Path

Weekly Performance: +86.67 percent | Market Cap: C$165.31 million | Share Price: C$0.42

Africa Energy continues among the week’s best mining stocks, maintaining focus on oil and gas exploration off South Africa’s coast. The company’s flagship asset, Block 11B/12B located 175 kilometers offshore, covers 18,734 square kilometers at depths between 200 and 1,800 meters. A recent restructuring agreement announced in May 2025 would grant Africa Energy a direct 75 percent stake, with environmental and social impact assessment approval required by May 2026.

Though the company has been quiet on announcements since late January, its participation in the week’s rally reflects energy sector momentum and renewed investor confidence in offshore exploration plays.

4. Gabriel Resources: Transylvania Gold Developer Navigates Regulatory Challenges

Weekly Performance: +60 percent | Market Cap: C$41.58 million | Share Price: C$0.16

Gabriel Resources remains among Canada’s best mining stocks despite long-standing permitting obstacles. The company has invested over US$760 million advancing the Rosia Montana gold project in Transylvania, Romania, which hosts 10.1 million ounces of gold and 47.6 million ounces of silver according to 2012 resource estimates. A decade-long regulatory standoff with Romania led to international arbitration through the World Bank’s ICSID mechanism.

Following dismissal of Gabriel’s arbitration case in March 2024, with Romania awarded US$10 million in legal costs, the company navigated enforcement proceedings through 2025. Recent developments indicate continued committee engagement, with hearings initially scheduled for January but subsequently postponed. The company’s inclusion among strong performers this week suggests market acknowledgment of potential resolution pathways.

5. Rio Silver: Peru Exploration Advances Toward Metallurgical Work

Weekly Performance: +48.05 percent | Market Cap: C$41.58 million | Share Price: C$1.14

Rio Silver rounds out this week’s best mining stocks, advancing its Maria Norte silver project in Peru. The exploration company recently secured local community approval to commence site activities, a critical milestone for development. Technical work announced in January confirmed silver mineralization grading up to 991 g/t in channel samples.

Rio Silver launched a metallurgical program in late January to assess project economics, with a private placement announced February 25 aiming to raise up to C$3 million, led by prominent investor Eric Sprott. Surface mapping and sampling are planned for Q3 2026, positioning the company for accelerated exploration advancement.

What Drives Performance Among Canada’s Best Mining Stocks?

The diversity among this week’s top performers—spanning tungsten, indium, natural gas, oil, gold, and silver—illustrates how geopolitical shocks, commodity price movements, and policy announcements collectively shape investor sentiment within Canadian mining equities. New Brunswick’s mineral strategy and international energy dynamics provided the backdrop for broad-based gains across the resource sector.

Investors tracking best mining stocks should monitor emerging developments: formal partnerships for flagship projects, completion of technical assessments, regulatory progress on stalled initiatives, and ongoing commodity price trajectories. The intersection of improved policy frameworks and elevated commodity prices creates a favorable environment for exploration and development stage companies.
