"Esperanza Resources [EPZ – TSX.V]
Current Price: $2.03
52 Week Range: $1.11 - $2.48
Mkt Cap: $108.90M
A big day for Esperanza raised the stock price by 4%, but this is indicative of the recent surge the stock has been running up 16% since February 2. Built around the model of using Joint Ventures to push its projects forward, Esperanza is involved in multiple projects in Peru and Mexico. Prospect generation is their nature, and they've got plenty to boast. Their primary focus is gold at its Cerro Jumil property in Mexico, but since we're writing about silver in this commentary, our attention is turned to the San Luis project in Peru. This joint venture project with Silver Standard Resources has a NPV of $109 million with projections of producing 1.9 million ounces of silver annually. Giving Silver Standard [SSRI - NASDAQ] the tab to bring this project into production lessens the risk involved, but does give Silver Standard the opportunity to seize and 80% interest. Given this company's track record of discovering projects, Esperanza has a solid model going forward, with room to grow. They've seen above $4 prices in the past, and there's confidence they can meet their pre-2008 levels again."
