1. Volt Carbon Technologies (TSXV:VCT)

Weekly gain: 50 percent
Market cap: C$16.56 million
Share price: C$0.075

Volt Carbon Technologies is a Canada-based battery material production and development company working to advance its dry separation graphite technology and its Solid UltraBattery platform.

The process is designed to produce fewer emissions, using no chemicals and zero water inputs, resulting in no liquid waste and no downstream contamination. It has achieved graphite with 98.5 percent purity.

Volt's Solid UltraBattery, a solid-state, lithium-based battery technology, is currently in the research phase.

In BC, the company owns two exploration projects: the Mount Copeland molybdenum and rare earth project near Revelstoke, and the Redbird molybdenum-copper-rhenium project in the Skeena Mining Division.

On Thursday, Volt announced that it received the initial 40,000 metric tons of vermiculite under its recent toll purchase order with Northern Ore. For a processing fee of US$100 per metric ton, Volt will process the material through its dry-air classification facility in Guelph, Ontario, to remove sand and grit.

The 40,000 metric ton order is set to renew automatically each year, unless terminated.

When the agreement was initially announced on July 7, the companies said they had also entered into a share issuance agreement under which Volt received a 2.5 percent equity interest in Northern Ore. The agreement also notes that Northern Ore has identified a high-grade graphite occurrence on its property.

Under the terms of the deal, Northern Ore will supply Volt with a minimum of 10,000 metric tons of graphite for processing each year, subject to laboratory testing.

2. PJX Resources (TSXV:PJX)

Weekly gain: 42.86 percent
Market cap: C$35.51 million
Share price: C$0.25

PJX Resources is an exploration company focused on gold, silver and base metal properties in BC, Canada.

The company has largely been exploring claims around Cranbrook, in the southeast portion of the province. PJX has been focused on the area due to the co-existence of a significant base metals deposit with untapped gold potential.

The region is home to the historic Sullivan mine, which produced most of the region’s production of over 285 million ounces of silver, 8.5 million metric tons of lead and 8 million metric tons of zinc.

Additionally, the company states that the region may be responsible for more than 1.5 million ounces of historic placer gold production, but significant gold deposits have not yet been discovered. In total, the company has amassed a land claim of over 50,000 hectares in the region, centered around these historic claim sites.

PJX's most recent news came on July 23, when it announced the start of a 4,000 meter drill program at Dewdney Trail property targeting Sullivan-style mineralization, and closed the second tranche of a non-brokered private placement, raising gross proceeds of C$6.3 million.

The company is also active at its Zinger property targeting a reduced intrusion-related gold system. Prospecting, mapping and surface sampling are being carried out at Zinger's Gar target, with plans to drill once it receives permits.

It intends to use the proceeds from the placement to finance exploration work at its properties.

3. Hercules Metals (TSXV:BIG)

Weekly gain: 35 percent
Market cap: C$250.94 million
Share price: C$0.81

Hercules Metals is an exploration company focused on its flagship Hercules copper-silver project in Idaho, US, which hosts the Leviathan copper porphyry discovery.

Its Hercules project covers 26,000 acres, including 7,700 acres of state lease for exploration, development and mining and 1,800 acres of surface mining rights. It entered into an option agreement with Barrick Mining (TSX:ABX,NYSE:B) in July 2025 to expand its landholding, gaining the right to earn a 100 percent interest in 74,000 acres.

The most recent exploration update from the Hercules project came on July 2, when the company announced it completed a 28 line kilometer induced polarization survey at the Hook target.

It identified a chargeability feature extending across a 1.8 kilometer strike length, which it says bears similarities to the geometry of the IP signature at the Leviathan discovery.

The feature appears to begin within 100 meters of the surface in some areas, which Hercules is targeting with a drill hole testing to a depth of 200 meters.

On Thursday, the company reported that it had appointed George Ogilvie as its new president and CEO, effective September 1. The former president and CEO of Arizona Sonoran Mining, Ogilvie has over 36 years of experience in mining, operations and development. Current CEO Chris Paul will become Hercules' senior vice president of exploration.

With his appointment, Ogilvie brings a team of six senior executives and mining professionals who were also with Arizona Sonoran. The company was recently acquired by Hudbay Minerals (TSX:HBM,NYSE:HBM) for C$2 billion.

4. Zentek (TSXV:ZEN)

Weekly gain: 28.38 percent
Market cap: C$98.76 million
Share price: C$0.95

Zentek is a diversified mining and technology company that is exploring the Albany graphite project and developing processing techniques to create graphene coatings through its ZenGUARD platform.

The Albany project is located near Hearst in Ontario, Canada, and consists of 521 mining claims covering 9,760 hectares of unpatented crown land. It hosts hydrothermal graphite in two breccia pipes.

One measures 300 meters long by 157 meters wide and is open at depth beyond 500 meters, while the other is 300 meters long by 50 to 75 meters wide and is open at depth beyond 600 meters.

On April 9, Zentek announced it is working to complete a new preliminary economic assessment and updated mineral resource estimate, which it expects to be completed in the summer of 2026. It noted that the previous estimate from April 2023 reported an indicated resource of 22.9 million metric tons of ore grading 4.07 percent graphitic carbon, with an inferred resource of 13.1 million metric tons grading 2.87 percent graphitic carbon.

In late June, the company formed a 90/10 joint venture called Strategic Graphite Partners with ALO Graphite Partners. The goal is to advance graphite from the Albany project into the US supply chain.

Zentek also has a technology arm that is developing graphene coatings for use in air filtration and personal protective equipment, fire protection for structural and industrial applications, ice prevention for aviation and infrastructure and anti-corrosion applications for marine and industrial uses.

It was granted a US patent for its ZenGUARD platform in June, and announced its first US commercial order on July 7.

5. CGX Energy (TSXV:OYL)

Weekly gain: 27.5 percent
Market cap: C$96.49 million
Share price: C$0.255

CGX Energy is an oil and gas exploration company with 27.48 percent ownership of a portfolio of wells in the Corentyne block off the coast of Guyana. Frontera Energy (TSX:FEC,OTCQX:FECCF) is the company's joint venture partner in the Corentyne block and also holds a 76.05 percent interest in CGX.

The Kawa-1 exploration well was drilled in 2021 and 2022 and encountered an active hydrocarbon system extending over a 6,000 foot column, mirroring trends in the Guyana-Suriname Basin. CGX’s Wei-1 well was drilled in late 2022 and is located on-trend between the Kawa-1 well and Exxon Mobil's (NYSE:XOM) Pluma discovery.

CGX and Frontera are currently in a legal dispute with the government of Guyana, which believes the petroleum prospecting license for Corentyne expired in 2024, a stance the joint venture disagrees with. The latest update on the matter mentioned plans to meet and discuss the situation, with potential dates in November or December of last year. However, this had not been resolved by the release of its annual report in March.

Shares of CGX posted gains this week, but the company has not released any news since April 30, when it announced its adoption of semi-annual reporting for the full year ending December 31 and the half-year ending June 30.
