EXHIBIT D <br /> (F) Nature, Depth And Thickness of The Ore Body [ Confidential] <br /> The West Side Placer ore body is a surface deposit covered by a thin layer of topsoil. Topsoil averages 8" - 16"in depth. The <br /> thickness of the ore body varies from 6 to 80 feet,with an average depth of 30 feet. This deposit is situated on top of the <br /> Wasatch Formation,which is estimated to be approximately 1600 feet thick.
