Endeavour Silver (AMEX: EXK) continues to stand out as an immutable engine of growth. Even after a significant retreat from recent highs, the stock remains some 82% above where it stood when I heralded a major growth spurt in the making back in August of 2010. Eager to continue an impressive six-year streak of expanding annual production volumes, Endeavour is targeting 3.7 million ounces of silver production in 2011 ... for a respectable 12.6% increase. I view near-term weakness in Endeavour's shares as an invitation to partake in one of the industry's foremost growth opportunities.
