The Government of New Brunswick announced a new comprehensive mineral strategy on Tuesday (March 3), at the 2026 Prospectors and Developers Association of Canada conference in Toronto.
The plan calls for a streamlined permitting process that will ensure clear communication and transparent timelines. Additionally, it promises a collaborative partnership with First Nations, science-based decision-making and a community-based approach to jobs, procurement and infrastructure.
Oil prices jumped significantly this week following the start of the US-led war against Iran. West Texas Intermediate has surged more than 25 percent since March first, climbing to over US$90 per barrel in trading on Friday, the first time since October 2022.
The most significant gains came on Friday, after Iran effectively stopped traffic through the Strait of Hormuz. More than 20 percent of the world’s liquefied natural gas and 25 percent of oil shipments travel through the strait.
The price rise has had a downstream effect on gas prices in Canada and the US, increasing by up to C$0.10 per liter and US$0.27 per gallon, respectively.
Over the past week, US producers have activated four additional rigs, bringing the total rig count to 411, although that total is down by 75 from the same period last year. Most companies are unlikely to rush to restart operations shuttered due to low oil prices until there is a more sustainable rise in oil prices.
Meanwhile, the war caused turmoil in bond markets as concerns over inflation and rising central bank interest rates seeped into the market. US two-year bonds rose by 18 basis points, while Britain’s rose by 43 basis points.

While the company did not release news this week, the project may benefit from the freshly announced New Brunswick Comprehensive Mineral Strategy. The report highlights Mount Pleasant’s indium, tin and tungsten mineralization.
2. Southern Energy (TSXV:SOU)
Weekly gain: 91.67 percent
Market cap: C$29.3 million
Share price: C$0.115

According to a February 2026 corporate presentation, current production from the company’s wells is about 11 million cubic feet of natural gas equivalent per day, with 27.9 million barrels of oil equivalent in reserves.
The company’s most recent news came on February 12, when Southern closed a non-brokered private placement that generated proceeds of US$23.5 million. The company said the funds will be used to repay the balance of a US$12.9 million senior credit facility, with the rest being directed to development capital, including the completion of two wells in Gwinville.

3. Africa Energy (TSXV:AFE)
Weekly gain: 86.67 percent
Market cap: C$165.31 million
Share price: C$0.42

The restructuring would result in Africa Energy owning a direct 75 percent stake in the block, with Arostyle holding the remainder. This is contingent on the asset being granted the production rights, which itself requires approval of its environmental and social impact assessment. The report must be submitted by May 2026.
Shares of Africa Energy posted gains this week amid energy market volatility.
The company has not released any news since January 26, when it announced the resignation of Dr. Phindile Masangane as Director and Head of Strategy and Business Development. She will still assist Africa Energy as a consultant.
4. Gabriel Resources (TSXV:GBU)
Weekly gain: 60 percent
Market cap: C$41.58 million
Share price: C$0.16
Gabriel Resources is a precious metals explorer and developer focused on advancing its Rosia Montana gold project. Based in Transylvania, Romania, Rosia Montana is in a region that has seen significant historic mining. Covering 2,388 hectares, the site is host to a mid-to-shallow epithermal system containing deposits of gold and silver.
The most recent resource estimate from a 2012 technical report shows proven and probable quantities of 10.1 million ounces of gold and 47.6 million ounces of silver. Gabriel has invested more than US$760 million into Rosia Montana, but has undertaken little development at the site since the early 2010s, as Romania blocked further development.
In 2015, the company entered into arbitration through the World Bank’s International Center for Settlement of Investment Disputes (ICSID) over permitting at the site and suggested that Romania was in violation of bilateral investment treaties. In March 2024, Gabriel issued a press release with an update saying that its case against Romania had been dismissed by the ICSID, which also awarded Romania US$10 million in legal fees and expenses. Gabriel said it would review the decision with its legal team and evaluate its options.
In March 2025, Gabriel announced that the committee had ruled that a stay of enforcement of the Award would continue if Gabriel guaranteed the proven solvency of the US$10 million.
The committee was scheduled to hold hearings on January 22 and 23 of this year, but on January 19, Gabriel reported that the hearings would be postponed to a later date. A new date for the hearing has not been announced.
The company did not release news in the past week.
5. Rio Silver (TSXV:RYO)
Weekly gain: 48.05 percent
Market cap: C$41.58 million
Share price: C$1.14
Rio Silver is an exploration company advancing its Maria Norte project in Peru. The property changed hands several times in the 18 years prior to Rio Silver’s acquisition in March 2025, but saw little exploration during that time.
However, in a February 5 release, the company noted that historic mining occurred as the site hosts a reclaimed waste dump. In that announcement, the firm said it plans to advance surface mapping and sampling in the third quarter of 2026.
Throughout January, Rio Silver made several announcements regarding its exploration and development timeline. On January 6, the company reported results from technical work at the site, confirming the presence of silver mineralization with grades up to 991 g/t in a 0.7 meter channel sample.
To end the month, the company said it was launching a metallurgical program at the site to assist in determining the project’s potential value.
The most recent news came last week in a pair of releases.
The first on February 25, the company announced a new private placement to raise proceeds of up to C$3 million. Funds will be used to advance work at the Maria Norte project. The placement is being led by Sprott (TSX:SII,NYSE:SII) Founder Eric Sprott.
The second release came on February 26 when Rio reported it secured permission from the local community to begin site activities at Maria Norte. The company said it will continue working with the community to develop a formal definitive agreement for long-term exploration and mining activities.
