[I don't hold WMX shares, and I didn't hold BLK shares, however I do follow MLD - MACA Ltd - who are the mining contractors at Wiluna.  By the way, BLK is also the NYSE ticker code for Blackrock, the largest asset management company in the world, which has nothing to do with Blackham Resources (now ASX: WMX, Wiluna Mining Corp), except they shared a ticker code.]
