Keith - is there a time in the next few days when you could stand
talking briefly about this on the phone? I think the fog about the
status of the Indigirka/Yakutua data could be cleared really quickly
that way. Once again, I'm really sorry it has been necessary to bother
you with this. Cheers, Malcolm
