Large cap miners are good to have and they're relatively safe, but they will not make you a lot of money. I had one miner which I bought for $0.18 and it went to $5.00. That's where you can make a lot of money and at $0.18, you aren't risking a whole lot. The exploration companies are the ones that make the huge gains and they aren't that hard to find. Watch IRVRF which I bought for $1.04 (now trading at $2.64), CNRIF which I bought as low as $0.015 (now trading at $0.11), ISVLF which I bought as low as $0.18 (now trading at $0.52), WTHVF which I bought as low as $0.15 (now trading at $0.66), and there are many more like these which I hold. And some of these low prices were just about 3-4 months ago.
