For you guys that love to invest in gold, may I suggest one important point... Invest in the commodity itself. Don't make it more complicated than it needs to be .
By investing in a miner, you need two things to go right.. The price of gold, and the miner to operate his business effectively.
How is this different than any other commodity, than say Oil ? Because gold has little utility and is looked at by the investment community as a "hedge". So, make your life simpler, and buy the commodity itself...
