Top 5 Canadian Mining Stocks This Week: St. Augustine Rises 67 Percent on Private Placement
Explore the week's best-performing Canadian mining stocks on the TSX, TSXV and CSE, and dive into the Canadian and US news affecting commodities prices and stock markets.

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 and US news impacting the resource sector.
A report released on Wednesday (June 11) by Canada’s Climate Institute suggests Canada risks missing out on a C$12 billion market for critical minerals should the government not drive investment in Canada’s mining sector.
The report outlines a growing need for minerals like copper, cobalt, lithium, nickel, graphite and rare earths, all of which are found in Canada. These critical minerals are all used to produce goods needed for the energy transition.
Overall, to meet this demand, the mining sector will require an estimated US$480 billion to US$750 billion in investment globally. To remain competitive, the institute suggests Canada will need to generate between C$30 billion and $65 billion in investments in upstream projects between now and 2040.
To reduce investor risk and ensure Canada and local communities see a net benefit, the report makes several suggestions aimed at different levels of government. It recommends the federal government collaborate with an arms-length financial institution to develop or expand risk-sharing agreements to support mineral assets through price volatility, and provincial governments strengthen mining regulations to mitigate risks and liabilities.
Additionally, it recommends both levels of government facilitate greater participation by Indigenous communities in mining projects through scaling up their resources for capacity and increasing their access to capital.
South of the border, the US Bureau of Labor Statistics released May’s consumer price index (CPI) data on Wednesday. The figures show a worsening of year-over-year inflation as all-items CPI ticked up to 2.4 percent from the 2.3 percent recorded in April. On a monthly basis, it rose just 0.1 percent versus the 0.2 percent the previous month.
Analysts had been expecting a steeper increase, but the numbers were offset by energy price declines in May.
However, the expectation is that higher figures will be coming over the next few months as the effects of the Trump administration’s tariffs begin to work their way through the economy. The slow response to the tariffs is primarily attributed to retailers working through inventories which were purchased prior to the tariffs coming into effect.
The CPI and other data will play a crucial role in the Federal Open Market Committee’s rate decision when it meets next week, on June 17 and 18. The overwhelming consensus by market watchers is the Fed will continue to hold the current range of 4.25 to 4.5 percent until its September meeting.
