NEW YORK ( TheStreet) -- Brigus Gold (BRD), Coeur d'Alene Mines (CDE - Get Report) and Goldcorp (GG - Get Report) climbed last week, while James River Coal (JRCC), Mines Management (MGN) and Silver Standard Resources (SSRI) eroded considerable value.
Brigus Gold emerged top gainer last week, jumping 11.5% after it was known that the company drilled more solid gold-mineralized intercepts near its Black Fox mine in Ontario. The strong gold grades from multiple drill holes attracted investors as they anticipate completion of the first resource estimate for the 147 zone, which is not far from Brigus' Black Fox gold mine, and this could further boost production there. The company is planning to have a 147-resource estimate in December.
Coeur d'Alene Mines gained 7.9% after an upgrade to buy from hold by TheStreet Ratings this past week. Goldcorp was up 4.4% after declaring its 11th monthly dividend payment of $0.034 per share for 2011. The dividend is payable Nov. 25, 2011.
