production costs

I do not hold but this company has been on my watchlist for about 12 months . I dont ususally post on shares i dont have shares in except as in this case to find information so I have some questions
1. has anyone got an idea of how much it will cost to get product to export i.e. build infrastructure such as a mine and specialist wharf facilities at say wyndham?

2. Would the company be more liokely to build a railway to wyndham or use a truck fleet?

I ask because having completed buying in another company I am getting ready for further investments albeit on a small scale
