I think that you will find that on this occasion 400% actually equates to a 4.8 mt resource of the highest grade lithium and not Zero as you stated in your post.
The resource has grown substantially and as the following taken from the announcement states.

The Seymour Lake Lithium Project contains Exploration Targets (2012 JORC Code) totalling4.5Mt - 7.2Mt @ 0.8%Li2O - 2.4%Li2O.

Now that's conservatively over 10 mt just on the pegmatites that we intersected /drilled and there are a lots and lots of other targets to get our teeth into. Just look at the what the other asx listed lithium company I have refered to in the past, have recently announced.( A new recently discovered pegmatite). The resource/spodumene that ADV own has always been of the highest quality and now we will have the tonnage as well. The stock market will wake up to this little beauty , soon enough. All people have to do is compare our resource with similar sized resource lithium companies and compare market cap. ADV is way way under valued for its lithium alone, not even taking into account our gold tenements and this will rerate when the market cops onto it.

All imo and DYOR
