Last week's PortfolioDirect/resources weekly investment report gave a portfolio grade rating to Renaissance Minerals Limited. PortfolioDirect/resources seeks to identify those stocks most likely to produce excess returns from exploration surprise using transparent assessment criteria. Of the four stocks reviewed, only Renaissance Minerals was rated a suitable portfolio alternative. The Renaissance activities are centered on exploration properties in Cambodia. Exploration has been founded on a valid analogue that matches the observed geology and points to a larger resource position with potential for material resource development. With drill testing of the Rhyolite Ridge and Area 1 targets to begin this month (subject to monsoonal conditions), the company's program of work has the capacity to deliver telling results from an investment standpoint within a reasonable timeframe.
