Most of us are aware of the nearology play that 4CE represents to AVZ.
I think I just bumped into who holds the tenements between the two - a Canadian company called Tantalex. There are quite a few good announcements and reports on their website.
Tantalex are pretty keen that the strike extends in a south westerly direction. In fact, they've located a potential pegmatite that visually looks like it might rest partly on their tenement, and partly on AVZ's.
I believe they started drilling in Q1, so if their results are good, there might be a flow on effect to 4CE.
