To Zinc Punter,
I wouldn't be hanging by the left one, waiting for a "quick result" from this drilling program. This is different in that they drill the holes in 2 stages(different ship drills each stage).
HDR has moved from being a daytraders stock to a long term hold (refer the positions taken by Fidelity & the instos). If you want to day trade IMHO probably better to find a specie to play with.
Cheers, Snoball.
