Numbers I've been using come from ILZSG and WBMS, but the numbers differ widely, and seem to be changing constantly depending on the day of the week. Some days it is hugely in surplus, next day the surplus is only going to be "small"
Even Tony Barnes in the presentations on 2007 full year results shows 2008 Zinc Balance as heavily in surplus (p24 -http://www.zinifex.com/common/files/2007_Full_Year_Results.pdf)
If these guys dont know, how are we suppose to make a sound judgement????
