This week's PortfolioDirect/resources investment report rated four companies: Discovery Metals (DML), Blackthorn Resources (BTR), Cape Lambert Resources (CFE) and Bauxite Resources (BAU). Of the four, Bauxite Resources is the only one to stand out at the moment as having a potentially world-class development, with extensive tenements adjacent to those of Alcoa and BHP Billiton in the southwest of Western Australia in what has proven to be a global hub for the mineral. There are a couple of flies in the ointment, so no need to rush, including a threat of legal action by a class action funder. It also needs to lock in rail and port arrangements but does have multiple choices with Kwinana, Bunbury or Albany all options.
