Near the base of the new unpermitted road and prior to crossing the La Plata River where a <br />mobile crusher and road construction material would be stored <br />3. At May Day Level 2 of the mine complex where fuel, potable water, and a portalet would be <br />located <br />The mine complex itself incorporates four locations — May Day Level 2 (lowest level), May Day <br />Level 1 (mid - level), May Day Level 3 ( "the Lamb "), and Idaho mine site.
