Toronto-listed Western Australia gold producer Superior Gold’s CEO Chris Bradbrook says a 1.25% state gold royalty hike in WA is “annoying” but “not hugely material to us”. He said at the 2017 Denver Gold Forum at Colorado Springs, Colorado, the company favoured Australia over Canada and the US for growth investment after it paid about A$40 million for the Plutonic assets in WA. “You could not buy an asset like that in Canada,” he said.
