Mining and energy companies feature prominently in the recently released OTCQX Best 50 2026 list, with seven resource-focused firms among the top 10 performers for this year’s edition.
The rankings evaluate companies based on a combination of one year total return and average daily dollar volume growth, offering investors insight into companies delivering strong performance across diverse sectors.
Below is a closer look at the seven mining companies that secured top 20 positions on the OTCQX Best 50 list for 2026, starting with the highest-ranked name on this year’s list.
1. Ucore Rare Metals (TSXV:UCU,OTCQX:UURAF)
Ucore Rare Metals claimed the top overall position on this year’s OTCQX Best 50 list.
Ucore is focused on developing downstream rare earths separation and refining infrastructure, with a particular emphasis on heavy rare earths used in permanent magnets for defense, clean energy and advanced manufacturing.
Central to that strategy is the company’s planned Strategic Metals Complex in Louisiana, US, which is being developed with backing from the Department of Defense and the state of Louisiana.
In August, Ucore moved to strengthen its future feedstock supply by signing a non-binding letter of intent with Critical Metals (NASDAQ:CRML) for a proposed 10 year offtake arrangement tied to the Tanbreez rare earths project in Southern Greenland. Deliveries will start in in 2027 or upon commercial production — whichever is later.
The company has also advanced the technical and financial foundations of its US refining plans. In mid-2025, Ucore and representatives of the defense department completed the formal project kickoff for an US$18.4 million Phase 2 award to support construction of the company’s first commercial-scale RapidSX separation system at the Louisiana site.
The Phase 2 funding focuses on demonstrating the effectiveness of Ucore’s proprietary technology in separating key rare earth elements, including dysprosium, a critical input for high-performance permanent magnets.
2. Discovery Silver (TSX:DSV,OTCQX:DSVSF)
Discovery Silver ranked third overall on this year’s OTCQX Best 50 list, capping a year marked by a major acquisition that repositioned the company as a Canada-based gold producer.
In early 2025, Discovery reached an agreement with Newmont (NYSE:NEM,ASX:NEM) to acquire the Porcupine operation in Ontario for total consideration of US$425 million. The deal represented the final phase of Newmont’s divestiture program as it streamlined its portfolio to focus on tier-one assets.
Located in Ontario’s Timmins Mining Camp, the Porcupine Complex is one of Canada’s most prolific gold-producing districts, with approximately 70 million ounces of gold produced since 1910.
The assets acquired by Discovery include the Hoyle Pond underground mine, one of North America’s highest-grade gold mines with more than 4 million ounces produced since the late 1980s.
Following completion of the acquisition, Discovery said it intends to continue both production and exploration activities across the Porcupine Complex as part of its broader growth strategy.
3. Andean Precious Metals (TSX:APM,OTCQX:ANPMF)
Andean Precious Metals placed fourth on this year’s list.
In November 2025, Andean secured a new US$40 million revolving credit facility with National Bank of Canada, enhancing its financial flexibility as it advances its strategic and operational priorities. Andean said the facility improves liquidity and provides a more efficient cost of capital compared with its previous arrangements.
Earlier in the year, the company entered into a long-term agreement with Corporación Minera de Bolivia (COMIBOL) to purchase up to 7 million tonnes of oxide ore from mining concessions located within a 250 kilometer radius of Andean’s San Bartolomé processing facility. The 10 year agreement provides Andean with a potential long-term source of feedstock, subject to economic viability under prevailing market conditions.
4. Lundin Mining (TSX:LUN,OTCPL:LUNMF)
In seventh place is Lundin Mining. In late 2025, Lundin agreed to sell its Eagle nickel-copper mine and the associated Humboldt mill in Michigan to Talon Metals (TSX:TLO,OTCID:TLOFF), consolidating its US nickel-copper assets under a single operator, while sharpeing its focus on larger-scale copper operations in Brazil and Chile.
The Eagle mine, which Lundin acquired in 2013, had been a long-running contributor to the company’s base metals portfolio. As of the third quarter of 2025, the operation had produced more than 194,000 metric tons of nickel and 185,000 metric tons of copper, generating over US$3.2 billion in revenue.
Aside from that, Lundin is advancing what it has described as a “generational” discovery at the Filo del Sol deposit in Argentina. Last May, the company released an initial mineral resource estimate for the Filo del Sol sulfide deposit, as well as updated resource estimates for the oxide portion of Filo del Sol and the nearby Josemaria deposit.
Held in a 50/50 joint venture with BHP (ASX:BHP,NYSE:BHP,LSE:BHP), the combined assets — collectively referred to as the Vicuña resource — rank among the world’s largest copper, gold and silver resources and are considered to be within the top 10 copper resources globally by size.
5. Graphite One (TSXV:GPH,OTCQX:GPHOF)
Claiming the eight spot on the OTCQX Best 50 list is Graphite One, which in November of last year confirmed the presence of rare earths at its Graphite Creek deposit, located north of Nome, Alaska. Geochemical analysis of drill core samples identified elevated levels of heavy rare earths, as well as all five principal permanent magnet rare earths.
Graphite One is currently advancing a fully integrated, US-based graphite supply chain, encompassing mining at Graphite Creek, transport through the port of Nome, and downstream processing at a planned advanced graphite and battery materials facility in Warren, Ohio. The Ohio complex is also designed to include a co-located recycling facility intended to reclaim graphite and other battery-related materials. The project has received significant federal backing, including a US$37.5 million Defense Production Act Title III grant.
6. G Mining Ventures (TSX:GMIN,OTCQX:GMINF)
G Mining Ventures placed ninth on this year’s OTCQX Best 50 list.
In 2025, shares of G Mining were added to several major equities indexes, including the NYSE Arca Gold Miners Index (INDEXNYSEGIS:GDM), the MVIS Global Junior Gold Miners Index, the S&P/TSX Composite Index (INDEXTSI:OSPTX) and the iShares MSCI Canada ETF (ARCA:EWC).
The company is anchored by the Tocantinzinho gold mine in Brazil and the Oko West gold project in Guyana. A key development came this past December, when the Guyana Geology and Mines Commission granted G Mining a 20 year mining license for its 100 percent owned Oko West project.
The mining license followed the issuance of a final environmental permit in September and the company’s formal construction decision in October. Early works that began under an interim environmental permit have continued under the final approval, allowing construction activities to progress without interruption.
7. Heliostar Metals (TSXV:HSTR,OTCQX:HSTXF)
Gold producer Heliostar Metals comes in at number 10 on the OTCQX Best 50 list.
Heliostar’s growth strategy is centered on its portfolio of Mexican assets, including two producing mines and four development-stage projects, which have become the foundation of its expansion plan. Ana Paula is its flagship development project, with a feasibility study scheduled for completion in H1 2027.
Alongside Ana Paula, Heliostar is focused on increasing production and extending mine life at its La Colorada and San Agustin operations in Mexico.
