Red Mountain Mining, Paladin Energy, Gryphon Minerals and Nickelore have been reviewed and rated this week in PortfolioDirect/resources. Red Mountain Mining, a Philippines gold explorer, was given a portfolio grade rating. It is suitable for an investor seeking to build a portfolio of investments where returns will be driven by exploration success. The PortfolioDirect rating system distinguishes between explorers, mine developers and companies with mature production profiles. The three categories take account of the different investment drivers and risk characteristics in the sector. Paladin Energy, the best known of the companies in the group reviewed this week, is in the third category. Without any significant organic growth, Paladin Energy is unable to demonstrate the necessary future value uplift for a portfolio grade rating.
