Welcome to the Investing News Network's weekly look at the best-performing Canadian mining stocks on the TSX, TSXV and CSE, starting with a round-up of Canadian news impacting the resource sector.
Statistics Canada released August’s consumer price index (CPI) figures on Monday (September 14). The data shows that inflation climbed 3 percent on an annualized basis during the month, matching July’s increase. On a monthly basis, CPI actually fell 0.1 percent in August.
Driving the annual rise was a 22.8 percent increase in gasoline prices versus the same period in 2025, following a 25.7 percent increase in July. StatsCan attributed the higher prices to the ongoing conflict between the United States and Iran, which has drastically slowed oil shipments from the Persian Gulf.
Excluding gasoline, CPI rose a slightly more modest 2.4 percent, but still higher than the 2.2 percent gain recorded in July.
The Government of Canada hosted the first Canadian Investment Summit on Monday and Tuesday (September 15). The event was created to generate investment into key sectors of the Canadian economy, including the resource sector, and to drive C$1 trillion in funding over the next 10 years.
On Tuesday, the Prime Minister's Office announced that the summit has met half of its investment goals so far, reaching C$500 billion.
The investments came from a variety of sources and included the launch of the Maple Fund, which will create C$50 billion in funding for critical infrastructure and strategic industries. The Canada Pension Plan Investment Board and Brookfield Asset Management (TSX:BAM,NYSE:BAM) created it as a partnership, with each organization contributing C$25 billion.
The Public Sector Pension Investment Board also committed to increasing its Canadian investments by 30 to 40 percent for an additional C$25 billion, for a total of C$100 billion.
Canadian banks were also on hand, promising C$325 billion in new financing, headlined by a C$150 billion commitment from TD Bank (TSX:TD,NYSE:TD), C$100 billion from Scotia Bank (TSX:BNS,NYSE:BNS), and C$70 billion from BMO (TSX:BMO,NYSE:BMO).
In parallel with the summit, the government also introduced the productivity mega deduction, which will allow companies to deduct a broader range of capital expenditures, effective the year new assets become available. The new measure will lower the effective marginal tax rate to 6.4 percent from 13 percent, roughly half the equivalent rate in the United States and the lowest in the G7.
In another news release on Monday, the government announced the advance income tax ruling program, which allows companies to request a binding decision from the Canada Revenue Agency on how tax law will apply to proposed transactions over C$1 billion before they are made.
The measure was designed to provide greater transparency and certainty to companies before they make significant investment decisions.

1. Orosur Mining (TSXV:OMI)
Weekly gain: 63.27 percent
Market cap: C$144.76 million

Orosur Mining is an exploration company focused on the development of early- to advanced-stage assets in South America.

Anzá consists of 15 mining concessions and 21 applications covering 17,293.45 hectares, and hosts three primary prospects: Pepas, APTA and El Cedro.
In February of this year, Orosur released a maiden mineral resource estimate for Pepas demonstrating an indicated resource of 201,000 ounces of gold from 1.14 million metric tons of ore grading 5.46 grams per metric ton (g/t) gold.
On Tuesday, Orosur released an exploration update on the project’s El Cedro target, at which it began drilling in late August. The release included assay results for the first 61.35 meters, from surface, of the maiden drill hole. The full 61.35 meter interval was mineralized, with an average grade of 0.93 g/t gold over its length, including a 42.15 meter interval grading 1.02 g/t gold.

On Tuesday, Bitterroot announced funding of up to US$5.22 million from the US Department of Defense. The funds will support half of the costs for exploration drilling, surveys and permitting.
“The Department of War’s DPA Title III funds are a significant investment in our shared goal to locate a high-grade domestic source of nickel,” CEO Michael Carr said. “The non-dilutive funds will reduce our cost of capital and allow the LM Project partners to finance and resume an aggressive drilling program on the highly prospective LM magma conduit.”
Then, on Wednesday (September 16), Bitterroot announced it planned to open a non-brokered private placement to raise up to C$2.4 million. Proceeds will also fund exploration work at the LM project and general working capital.

Market cap: C$33.48 million
Share price: C$0.83
Firefox Gold is an exploration company working to advance its Mustajärvi gold project in Lapland, Finland. The property covers an area of approximately 12 square kilometers and hosts more than 2.1 kilometers of strike with gold mineralization.
The company released two project-related announcements this week.
The first came on Monday, when FireFox reported assay results from seven holes of its most recent drill campaign. One highlight came from a hole in the Northeast Zone, a 7 meter interval with visible gold and an average grade of 11.36 g/t gold from a depth of 199 meters, including a smaller 1 meter section grading 57.9 g/t gold.
Then on Wednesday, FireFox reported the discovery of the new Lammas Zone, located almost 1 kilometer to the east of the main Mustajärvi Shear Zone. The discovery hole returned an average grade of 4.13 g/t over 21 meters from a depth of 114 meters, which included a 1 meter interval grading 21.6 g/t.
“The results from this hole indicate just how much potential for discovery and expansion remains in the Mustajärvi Shear Zone system,” CEO Carl Löfberg said. “Here at Lammas, work is just beginning, but this structural trend appears to have continuity over some appreciable distance.”
4. Highway 50 Gold (TSXV:HWY)

Share price: C$0.79
Highway 50 Gold is an exploration company advancing a portfolio of projects in Nevada, US.

“New discoveries are extremely rare in mature exploration terranes,” CEO and President Gordon Leask said. “This discovery is a direct result of management’s efforts in generating a novel understanding of the deep crustal architecture responsible for the emplacement of the major gold districts of north-central Nevada.”
The company also reported it staked 205 new claims around the discovery area. According to the project page, Gold Knob previously comprised 514 unpatented claims.

FAQs for Canadian mining stocks
What is the difference between the TSX and TSXV?
The TSX, or Toronto Stock Exchange, is used by senior companies with larger market caps, and the TSXV, or TSX Venture Exchange, is used by smaller-cap companies. Companies listed on the TSXV can graduate to the senior exchange.
How many mining companies are listed on the TSX and TSXV?
As of July 2026, 892 mining companies and 68 oil and gas companies are listed on the TSXV, combining for 64 percent of the 1,501 total companies listed on the exchange.
The TSX is home to 182 mining companies and 51 oil and gas companies. The exchange has 2,264 companies listed on it in total.
Together, the TSX and TSXV host around 40 percent of the world’s public mining companies.
How much does it cost to list on the TSXV?
There are a variety of different fees that companies must pay to list on the TSXV, and according to the exchange, they can vary based on the transaction’s nature and complexity.
As of April 2026, the listing fee alone will most likely cost between C$10,000 to C$70,000, and accounting and auditing fees could rack up between C$25,000 and C$100,000. Legal fees are expected to be over C$75,000 and an underwriters’ commission may hit up to 12 percent.
The exchange lists a handful of other fees and expenses companies can expect, including but not limited to security commission and transfer agency fees, investor relations costs and director and officer liability insurance.
These are all just for the initial listing, of course. There are ongoing expenses once companies are trading, such as sustaining fees and additional listing fees, plus the costs associated with filing regular reports.
How do you trade on the TSXV?
Investors can trade on the TSXV the way they would trade stocks on any exchange. This means they can use a stock broker or an individual investment account to buy and sell shares of TSXV-listed companies during the exchange's trading hours.
