Joseph Gutnick back with another gold play in WA JOSEPH Gutnick, the Melbourne-based investor who at one point controlled half the active goldmines in Western Australia, is understood to be dipping his toe in the water again with an investment in Western Australian tiddler Blackham Resources. Blackham, which listed in 2006 at 20c and has a promising brownfield gold resource called Matilda near Wiluna in WA, requested a trading halt on Friday at 15c. Blackham was founded by Cazaly Resources' Nathan McMahon, who still owns just over 10 per cent of its capital.
