a bounce that can't last or just the beginning?

Wow...love that share price! Basically up $4 in 2.5 weeks. The question for a long term holder like myself that rather than selling actually wants to accumulate more....is this a bounce that can't last or is this about to really take off and never look back?

Considering:
- Share buyback
- Liklihood of uranium deal with China
- Suggested 10-20% increase in Iron Ore contracts
- Base metal shortages continuing to drive prices up
- Oil price looking shakey and potentially going up as gasoline stocks fall to all time lows

I'm used to the patterns of BHP's share price however in this case there seems no shortage of potential good news which could simply continue to push the price higher before perhaps the $30 mark is reached (where a number of broker valuations sit) and there could be some resistance?

Any thoughts appreciated!! I don't want to miss getting some more shares before the Uranium deal and others could put this thing a bit too high for my liking?!
