That's 0.7% "tin equivalent", not tin. The tin content at 0.45% tin equiv cutoff is 0.4%, which is equal to the average %Sn deposit alone according to their announcements.

Whilst I can see why they use the term, I find it confusing and annoying. The figure depends on a fixed price ratio between Sn/W/Fe, so will change with time. Also, the "equivalent" part gets missed out in the telling such that people think of it as 0.7%tin...... PLUS tungsten and iron.

I'd prefer them to just stick with the "3-in-1" pitch that they have used and list the metals separately.

Whinge, whinge.... these shareholders are never happy!!
