Supporting documents are attached. <br /> 6.4.3 EXHIBIT C -Pre-mining and MininE Plan May(s) of Affected Lands <br /> 1. Map information:Pursuant to Rule 6.4.3, the Exhibit C maps are required to portray the <br /> following information: <br /> a. Names of creeks and roads.

Furthermore, nearly the entire proposed pit appears to be within the 100- <br /> year floodplain.
