• 1.2 Packrat Mine <br />The Packrat Mine is an older mine that probably was first developed in the 1950's and consists of <br />several miles of drifts with numerous stopes or rooms mined off of each drift. The three Packrat Mine <br />portals are located approximately one-half mile north of the Whirlwind portal and almost 300 feet <br />lower in elevation. The Packrat portals access the Salt Wash directly from the side of Lumsden Canyon <br />(see Maps C-lA and C-2). <br />The mine workings extend in a southwesterly direction though the Salt Wash unit (see Map C-1B), <br />which is relatively flat lying (the formations dips to the northeast at one to three degrees). Early miners <br />used track methods to mine most drifts. The drifts in the south part of the mine are still relatively small <br />with a width of about six feet. The northern drifts were later widened and extended using rubber tired <br />equipment and are typically nine feet high by twelve feet wide. The Packrat Mine had two ventilation <br />shafts; a sixty-inch diameter shaft near the end of the northern workings and athirty-six-inch shaft <br />called Ten Straight near the end of the southern workings. The larger ventilation shaft was backfilled <br />as part of reclamation, but the Ten Straight is still open and protected by a metal grate. <br />• <br />The Packrat Mine operated until 1990 when depressed uranium prices caused it to go on standby. <br />Umetco later reclaimed the mine surface area in 2002. Energy Fuels reopened the mine in early 2007 <br />under prospect permit P-2007-003. Under this permit, the road to the Packrat and the main portal were <br />reopened. A small pad area (less than 0.6 acre) was established in front of the portal. This work was <br />completed in May 2007 and is not shown on Map C-lA. Energy Fuels is currently establishing <br />ventilation and rehabilitating portions of the Packrat Mine so that exploration activities can be safely <br />conducted. <br />This permit application outlines further modifications to the site for the full mine operation. Surface <br />disturbances associated with exploration activities are included in this application so that the 112d <br />Permit will incorporate and supersede existing exploration permits. <br />• <br />Whirlwind Mine 07 (rev.
