Peninsula Minerals has said that it has completed 175 development drill holes during March and April 2010 for a total of 85,933ft at the Ross Project. Numerous high-grade intersections were encountered including 7.5ft at 1,370ppm U3O8 returned from drill hole RMR0399.

During this period, the focus of the drilling was on enhancing the grade and definition of the existing drill-defined resources and to convert inferred resource to indicated status, the company said.

Three drill rigs are currently engaged at Ross chasing extensions of the known target zones identified by the resource model. A fourth rig continues to test sparsely drilled target zones, with the aim of expanding the current JORC compliant resource.

The company said that out of the completed 175 drill holes at Ross, 78 holes encountered significant mineralization. A total of 26 holes recorded multiple stacked intersections of uranium mineralization.

The focus of the drilling in March and April has been predominantly within the resource zones in Sections 18 and 19. In Sections 19, 13 and 7, there are resource target zones that have yet to be tested. Three rigs are currently operating to expand these mineralized systems.
