1. Century Global Commodities (TSX:CNT)

Weekly gain: 228.57 percent
Market cap: C$18.32 million
Share price: C$0.115

Century Global Commodities is an iron ore exploration and development company focused on its Joyce Lake iron ore project in Newfoundland and Labrador, Canada.

The property consists of 682 mineral claims covering a land area of 17,049 hectares, near the border of Labrador and Québec. Iron ore mining in the region dates back to the 1950s, with the Iron Ore Company of Canada producing more than 150 million short tons from its Schefferville operation between 1954 and 1982.

A December 2022 technical report estimated proven and probable reserves of 17.37 million metric tons of ore at average grades of 59.94 percent iron, 11.28 percent silicon dioxide, 0.55 percent aluminum oxide and 0.76 percent manganese.

At the time, the company demonstrated project economics with a post-tax net present value of C$184.6 million at an 8 percent discount rate, an internal rate of return of 20.01 percent and a payback period of 3.7 years.

The most recent news from Century came on June 26 when it released its financial results for the year ending March 31, 2026. The report noted that it had free cash, deposits and securities totaling C$2.4 million and working capital of C$5 million, which it said was adequate to support near-term administrative and mineral property development costs.

Century also reported C$13.8 million in revenue from its food distribution business in Hong Kong. The company established the subsidiary in 2015 to generate profits that could supplement its mining exploration arm.

2. Tethys Petroleum (TSXV:TPL)

Weekly gain: 52.78 percent
Market cap: C$126.34 million
Share price: C$1.10

Tethys Petroleum is an oil and gas exploration and production company focused on advancing operations in Kazakhstan.

The company holds a portfolio of production contracts in the North Ustyurt Basin west of the Aral Sea. The properties consist of the Kyzyloi production contract, the Akkulka and the Kul-Bas exploration licenses and production contracts.

On May 28, Tethys released its Q1 Interim Results and Corporate Update. In the report, Tethys said that oil and gas sales increased 104 percent during the quarter to US$8.1 million from US$3.97 million in the first quarter of 2025, and net profit totaled US$2 million. It attributed the rise in sales to increased petroleum output.

However, it also noted challenges regarding domestic oil sale prices and difficulties securing payments from the approved buyer of its natural gas. Due to these issues, Tethys said it would delay its planned drilling of ARD-01, which is now expected later in 2026.

Positive news for the company came this week. On Friday, Tethys announced that a Kazakhstan court ruled in its favor, overturning the forced sale of gas assets owned by its local subsidiary Tethys Aral Gas (TAG). Instead, the court indicated that TAG should be allowed to proceed with the sale of assets on a voluntary basis, which could allow TAG to receive a higher price for them.

The ruling comes as part of a long dispute surrounding a loan by a bank to Eurasia Gas Group (EGG), TAG's former oil customer. TAG used certain gas infrastructure assets as collateral for the bank loan, and EGG advanced certain funds to TAG. While the subsidiary maintains it repaid EGG, the funds were not given to the bank.

The claimant in the case is DFSK, an affiliate of the bank that was tasked with recovering EGG's bank debts from TAG in 2018. DSFK will have 10 days to appeal following the release of the full written decision, which is expected within the next five business days.

3. Star Diamond (TSX:DIAM)

Weekly gain: 50 percent
Market cap: C$19.35 million
Share price: C$0.03

Star Diamond is an exploration and development company working to advance its flagship Fort à la Corne diamond district in Saskatchewan, Canada.

The property is located 60 kilometers east of Prince Albert, Saskatchewan. Previously a joint venture with Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO), Star Diamond acquired Rio Tinto’s stake in the project in March 2024 in exchange for 119.32 million shares in Star Diamond, resulting in Rio Tinto holding a 19.9 percent ownership position in the diamond junior.

Fort à la Corne has seen extensive exploration of kimberlite deposits, including geophysical surveys, large-diameter drilling and micro- and macro-diamond analyses.

The Star-Orion South diamond project, the most advanced project area in Star Diamonds' portfolio, is located within the district.

In 2018, the company released a PEA for Star-Orion South estimating an economic case with a post-tax net present value of C$2 billion, an internal rate of return of 19 percent and a payback period of 3 years and 5 months.

In July 2024, the company published an updated mineral resource estimate. In the indicated category, the Star Kimberlite pipe hosts 34.8 million carats, grading 19.4 carats per 100 metric tons (CPHT) from 179.6 million metric tons of ore, while the Orion South pipe hosts 36.94 million carats, grading 17.9 CPHT from 206.6 million metric tons.

In Star Diamond’s first-quarter results released on May 8, it said the project is currently on care and maintenance, and the company is currently working on a pre-feasibility study as part of its progress towards a future development decision. It did not provide a timeline for completion of the study.

Additionally, Star Diamond noted that three other projects within the Fort à la Corne district – Orion North, Orion Centre and Taurus – were under review to determine the future work needed.

4. Buffalo Potash (TSXV:BUFF)

Weekly gain: 44.23 percent
Market cap: C$50.28 million
Share price: C$0.75

Buffalo Potash is an exploration and development company advancing its Disley project in Saskatchewan to production of potassium chloride, commonly known as muriate of potash (MOP).

Disley covers an area of 10,610 kilometers northwest of Regina and is located adjacent to the K+S (ETR:SDF,OTCQX:KPLUF) Bethune potash mine.

On April 27, the company released the results of a preliminary economic assessment demonstrating economics of a post-tax net present value of US$1.1 billion with an internal rate of return of 30 percent.

The included mineral resource estimate reported measured and indicated resources of 582 million metric tons of potassium chloride from 1.67 billion metric tons of ore grading 34.8 percent potassium chloride.

On July 6, Buffalo published a roadmap for the site’s development, starting with the initial production module, the first of three planned facilities. The module is designed to produce 125,000 metric tons of soluble-grade MOP annually, with first production targeted for the first quarter of 2027. In the future, the Disley West and Disley East mines would combine to produce 1 million metric tons of granular-grade MOP per year.

5. McFarlane Lake Mining (CSE:MLM)

Weekly gain: 44 percent
Market cap: C$163.4 million
Share price: C$0.36

McFarlane Lake Mining is a gold exploration company working to advance its flagship Juby gold project north of Sudbury, Ontario, Canada.

According to a September 2025 report, the asset hosts an indicated resource of 1.01 million ounces of gold with an average grade of 0.98 grams per metric ton (g/t) from 31.74 million metric tons of ore, with an inferred resource of 3.17 million ounces grading 0.89 g/t from 109.48 million metric tons.

The company's most recent exploration update came on June 22, when it reported that extension drilling at the Golden Lake deposit encountered wide mineralization to the west, with one hole returning 0.59 g/t gold over 155 meters, which included an interval of 0.7 g/t over 75.8 meters.

“The continued extension of the mineralization envelope to the west is very encouraging. These broad zones of mineralization are important for improving the economics of mining,” Mark Trevisiol, McFarlane’s CEO, said in a release.

The announcement also indicated that the company will use the results to complete a preliminary economic assessment later in the year.

In addition to exploration work, McFarlane has also been working to raise capital. On June 5, it reported the closing of a C$6.75 million private placement led by Michael Gentile, who agreed to subscribe to C$6.35 million of the offering. Pierre Beaudoin, director at Coeur Mining (TSX:CDE,NYSE:CDE), subscribed to the remainder.
