Probably a good idea to buy very soon. I was very fortunate that I physically drove to my broker to deposit funds on Tuesday, so that I could buy more Kimber on market's open Wednesday. A run, do not walk type of situation if you will. I bought at 69 cents. That turned out to be MINUTES before the run to 97 cents. Same thing in Silver Standard yesterday. I bought in at $14.88 right before the big move to about $19 or so yesterday.
You have to be in it to win it. Long term, this is a great place to be. Kimber is my favorite non-producing Explorer, and has been for over 3 years. It was one of the first gold stocks I bought when I discovered the sector.
