Last week’s other top-gaining mining stocks on the TSX were Sierra Metals, Lundin Mining, Copper Mountain Mining and Orocobre.

The S&P/TSX Composite Index (INDEXTSI:OSPTX) was up last week, increasing 0.28 percent to close the five-day period at 15,741.94.

The index edged up in early trade on Friday (March 16), supported by an increase in the financial and energy sectors.

On Friday, the gold price was up on the back of a weaker dollar and political concerns. Silver also inched up, while copper was on track for a weekly loss.

Despite those factors, a number of stocks in the mining sector saw significant share price increases last week. The five top gainers are as follows:

  • Sierra Metals (TSX:SMT)
  • Arizona Mining (TSX:AZ)
  • Lundin Mining (TSX:LUN)
  • Copper Mountain Mining (TSX:CMMC)
  • Orocobre (TSX:ORL)

Here’s a look at those companies and the factors that moved their share prices last week.
