Gina Rinehart has been showcasing her massive Roy Hill mine to investors, but it has not impressed all part of the local industry.

One business analyst says the timing of $10 billion iron ore project is ‘abominable’.

Roy Hill mine is more than 76 per cent complete, and Ms Rinehart intends for it to start its 55 million tonne per annum output in September.

The massive project included the construction of 344 kilometres of railway and a new port at Port Hedland.

It will allow its owners – Hancock Prospecting, Marubeni Corp, POSCO and China Steel – to enjoy an iron value currently at a six-year low.

Morningstar analyst Matthew Hodge says when investors take a tour of the site; there may not be as much joy as expected.

“The timing is abominable,” Hodges told News Corp reporters.

“They're forcing supply into a market that doesn't want it.”

Similarly, analyst David Lennox says Roy Hill is in the “worst position of all” iron ore industry members.

“The mine was being developed at a time, like Fortescue, when the costs were high and they're going to come smack bang to the market in the middle of a deadly iron ore price,” Lennox said.

“If you're making a loss on every shipment of iron ore you've got to make up that drain on your cash somewhere.”

More broadly, the experts predict an iron ore price recovery will not come until at least 2016, and even then would rely on high-cost Chinese producers exiting the market.
