The International Speculator in its Oct. 7, 2011, issue, refreshes its buy of Great Panther Silver Ltd. at $2.54, officially, "Buy first tranche." This is the second go-round with the Mexican silver miner. The newsletter said buy three times between May 2, 2006, and July 2, 2007, at prices ranging from $1.81 to $2.30. It then said sell on May 1, 2008, at $1.08. Assuming an investment of $1,000 for each of the three buys, the Speculator's sell yielded a loss of $1,502. The newsletter then said buy in its Sept. 5, 2011, issue, at $2.87. Assuming another $1,000 investment, the holding is worth $876. Great Panther was among several sells in mid-2008, one of the Speculator's occasional house-cleaning exercises. Then, the writer said Great Panther enjoyed improving production at Guanajuato in Mexico. The problem was the time lag until production topped out. The current buy follows a site visit by chief metals & mining investment strategist Louis James, who noted improving results from Guanajuato. The company is on track to increase production from 2.3 million ounces AgEq last year to 2.9 million ounces this year. The writer also likes Great Panther's recent high-grade drill results and figures the stock is on sale.
