The gold price was in focus this week as it climbed to a new record high Wednesday (September 3) on expectations of a September rate cut by the Fed and news on August 29 that a federal appellate court had struck down the majority of Trump’s reciprocal tariffs. Gold ended the week up 4.03 percent at US$3,586.27 per ounce after the lackluster jobs report pushed gold above Wednesday's highs.

1. Carlton Precious (TSXV:CPI)

Weekly gain: 77.78 percent
Market cap: C$17.74 million
Share price: C$0.24

Carlton Precious is an explorer focused on precious metals projects in the Americas and Australia.

Its flagship Esquilache silver project, located in Peru, consists of two mining concessions covering an area of 1,600 hectares. Unsubstantiated records from the property indicate historic mining produced 10 million ounces of silver between 1950 and 1962. Exposed structures show mineralization of silver, lead, zinc, copper and gold.

On March 19, Carlton reported assay results from a 2024 surface channel sampling program, with grades peaking at 13.45 grams per metric ton (g/t) gold and 1,018 g/t silver.

The company's most recent announcement came on July 14, when Carlton signed an agreement with the community of San Antonio de Esquilache for the project allowing for further exploration at the property. Carlton added that its staff has designed a program of up to 40 drill holes that it expects to commence in fall 2025.

In a September investor presentation, the company stated it is submitting its drill permit applications.

2. Quantum Critical Metals (TSXV:LEAP)

Weekly gain: 73.68 percent
Market cap: C$17.31 million
Share price: C$0.165

Formerly Durango Resources, Quantum Critical Metals is a polymetallic exploration company developing a portfolio of projects in Québec and BC, Canada. Its flagship NMX East critical metals project is in the Eeyou Istchee James Bay region of Québec and lies adjacent to Nemaska Lithium’s Whabouchi mine. According to the project page, the company has drilled four holes at the property, producing a highlighted assay of 107.68 meters from surface containing average grades of 38.85 g/t gallium, 701.03 g/t rubidium, 24.98 g/t cesium and 3.61 g/t thallium.

Quantum Critical Metals has also been working to advance its Victory antimony project in Haida Gwaii, BC. The site was initially discovered in the 1980s and hosts mineralization of arsenic, antimony and mercury. On August 25, the company announced it submitted an application to expand the property to 1,444 hectares.

The company’s most recent news came on Thursday (September 4), when it identified mica as a key carrier of critical minerals at NMX. Quantum selected samples from the 107.68 meter interval mentioned above, and the samples with the highest mica content returned significantly higher grades of critical metals.

Quantum has now sent the samples for further testing. If the testing confirms the results, stated the discovery will allow for easier removal of these elements from the rock, as the company can first isolate the mica.

3. Electric Metals (TSXV:EML)

Weekly gain: 66.67 percent
Market cap: C$79.98 million
Share price: C$0.45

Electric Metals is a mineral development company focused on advancing its flagship North Star manganese project in Minnesota, US. According to the company, the asset is North America’s highest-grade manganese resource. It plans to produce high-purity manganese sulphate monohydrate for lithium-ion batteries.

On August 26, Electric Metals released a preliminary economic assessment (PEA) for North Star. It demonstrates a base-case after-tax net present value of US$1.39 billion, with an internal rate of return of 43.5 percent and a payback period of 23 months. The report also includes an updated resource estimate with an indicated resource of 7.6 million metric tons of ore grading 19.07 percent manganese, 22.33 percent iron and 30.94 percent silicon, and an inferred resource of 3.73 million metric tons of ore grading 17.04 percent manganese, 19.04 percent iron and 30.03 percent silicon.

Momentum from the PEA release landed Electric Metals on this list of top performers last week, and its shares climbed even higher this week after the company announced the results of its annual and special shareholder meeting.

Shareholders approved all resolutions, including two related to Electric Metals’ plan to redomicile its business in Delaware, US. The first is continuance from the Canada Business Corporations Act to the Business Corporations Act of BC. Shareholders also voted to authorize a continuance of the company to the Delaware General Corporation Law, with the condition of a successful corporate move to BC.

Electric Metals CEO Brian Savage said the change is intended to align its corporate home with the company’s mission to build a fully domestic US supply of manganese.

4. Valhalla Metals (TSXV:VMXX)

Weekly gain: 66.67 percent
Market cap: C$11.53 million
Share price: C$0.15

Valhalla Metals is a polymetallic exploration company working to advance a pair of projects in Alaska’s Ambler Mining District. Its Sun project consists of 392 claims that cover an area of 25,382 hectares. A May 2022 technical report states that the indicated resource for the project is 1.71 million metric tons of ore containing 162.96 million pounds of zinc, 55.85 million pounds of copper, 42.04 million pounds of lead, 3.3 million ounces of silver and 12,000 ounces of gold.

The project is largely dependent on the construction of the 211 mile Ambler Access Road, which Trump approved in his first term. Former President Joe Biden rescinded the federal permit in 2024 due to environmental concerns.

Shares in Valhalla gained momentum this week after Congress voted 215 to 210 on Wednesday to move ahead with the project. It’s expected that the Senate will follow suit when it votes on the resolution in the next few weeks.
