There are always plenty of mining stocks to buy. The secret to finding a lasting investment in mining is to discover the stock that is not tied to the output of a single mine. These single shaft high flyers can go up quickly, but they also die rapidly once their ore bodies play out.

Gold Bullion Development Corp. (CDNX:GBB.V) (Other OTC:GBBFF.PK) (the "Company" or "Gold Bullion") announces that it has completed 6,842 m in 12 holes of diamond drilling in its first drill campaign on the Castle Silver property historic past-producing silver mine property located 85 kilometres northwest of the historic silver camp in Cobalt, Ontario.

Gold prices continue to linger around heady all time highs yet gold mining stocks have not enjoyed the same wild degree of success. Globally, new gold mines are cropping up such diverse places as China, the Philippines, India, Eritrea and Brazil yet the promised rich returns for investing do not seem to meet investor expectations.

The leading gold and silver mining stocks have recently lagged the precious metals themselves. Sometimes the leading mining stocks will lead the metal, however, they have been lagging the precious metals since mid-March 2011. Gold and silver are making new highs this morning while the Market Vectors Gold Miners ETF(NYSE:GDX) is still trading below its December 2010 high which was $64.62 a share.
