It's always difficult to pare a long list of potential highfliers down to a single favorite stock, but when I asked myself which of my own gold and silver holdings I'd be buying more of at this juncture, Gammon Gold came out right on top. While an array of smaller-cap alternatives could well outperform these shares, I consider Gammon the ideal combination of existing market heft, incredible growth potential, and a decidedly undervalued share price. I recently identified three specific developments that could jump-start these shares over the coming months, and over the long term I expect Gammon shares to appreciate handsomely.
