Papillon Resources (PIR), Lucapa Diamond Company (LOM), Rox Resources (RXL) and Ironbark Zinc (IBG) have been reviewed and rated in the latest weekly PortfolioDirect/resources investment report. Ironbark Zinc is an example of a company battling against the odds to extricate itself from the 'Phase I value trap'. Meanwhile, Papillon Resources seems more likely to make the transition. Rox Resources has been given one of the top ratings for an explorer but Lucapa Diamond Company brings a couple of additional advantages. Diamond exploration lends itself to exploration surprise but, more importantly, as it enters production it can be used in a portfolio to modify the inevitable exposure to Chinese business conditions experienced by most companies in the sector.
