There is a more than touch of irony in the news that Gina Rinehart has purchased a 10% stake in Ten Network, given her well-known dislike of giving media interviews or revealing very much at all about her vast mining empire, Hancock Prospecting.

While the Ten stake won't exactly mean that Rinehart will be appearing regularly on Ten Network's 7PM Project, it will mean at least a small slice of her empire will be open to a great deal of public scrutiny.
