Canada’s mining sector delivered strong gains this week, with junior mining stocks leading the charge amid shifting inflation data and central bank policy expectations. Investors looking for high-growth opportunities in Canadian mining stocks have reason to take notice, as several TSX Venture Exchange (TSXV) and CSE-listed companies delivered double-digit returns.

Here’s a breakdown of the top 5 performing Canadian mining stocks this week, based on share price gains as of market close on Friday, July 18, 2025.

📈 Market Overview: Inflation, Interest Rates & Commodity Prices

Canada’s June CPI rose to 1.9% year-over-year, up from 1.7% in May, driven by softer gasoline price declines and increased prices in durable goods and groceries. Despite expectations for a 2% rise, the figure suggests that the Bank of Canada may delay further interest rate cuts at its upcoming meeting on July 30.

Meanwhile, the S&P/TSX Composite Index hit a new all-time high, closing at 27,314.01, while the TSX Venture Index jumped 2.53%, ending the week at 797.75.

On the commodity side:

• Gold prices climbed to US$3,349.66/oz, up 0.78%

• Silver surged 3.13% to US$38.15/oz

• Copper remained strong, trading near record highs at US$5.60/lb

These bullish commodity trends provided a tailwind for several small-cap mining stocks in Canada.
