Listen to the conference call, and if you don't hear the answer, then ask them the question. There may be more reasons for the increased cut off price than higher gold prices - one of the research reports on Victoria mentioned this fact and it (if I recall correctly) had something to do with the angle of drilling that may be done. I hope they have a replay of today's conference call. I won't be able to tune in to it, so please ask your questions when you tune in, and please report on this site the answer to your question regarding cut off levels.
Thanks.
