reading through the announcement in more detail, the statement " giving rise to significant total upside tonnage potential" confirms what my thoughts are about the conservative early estimations of 1.7 to 3billion tonnes.
Figure 4B shows samples at 506.25m with 90% magnetite and the announcement refers to the incline extending 1km with near surface ( "shallow depths"). All sounds pretty good to me.
I can't remember reading anywhere about 90% magnetite in such large expanse before. The diagram shows the incline with the magnetic measurements coming through in thick width to shallow depths 1km from the hole, how good is that for potential tonnage and high grade magnetite.
I think this is really going to get some great media coverage in the not to distant future. But , hey, I could be wrong ( but I don't think so), :-))))
