Odd numbered cuts 13 through 21J _ <br />`i ~ <br />should not be included in the mine plan given the uncertainty . <br />of their location pending exploration J <br />4. Paragraph C, water diversions and impoundments is unclear as to <br />the matter of rerouting Bear Creek.

Flatter than 2:1 could be 2.1:1 as a matter of extreme. <br />Final contours for the refuse areas are not shown.
