The remaining areas to be <br />disturbed have also been impacted, but to a lesser extent, by historic exploration activities consisting <br />primarily of road and pad construction. Surface disturbance on previously undisturbed ground is <br />largely confined to the waste pile expansion on the east end of the Whirlwind portal site. <br />Whirlwind Mine 07 (rev.
