Underground exploration activities have included rehabilitating the existing workings to gain safe <br />access to the ore body plus geological and environmental sampling. Energy Fuels plans to collect a <br />bulk ore sample by driving a drift between the Urantah Decline and the Packrat Mine (see Map C- <br />1 B). <br />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 <br />Mine portals are located approximately one-half mile north of the Whirlwind portal and almost 300 <br />feet lower in elevation. The Packrat portals access the Salt Wash directly from the side of Lumsden <br />Canyon (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). Eazly <br />miners used track methods to mine most drifts. The drifts in the south part of the mine are still <br />relatively small with a width of about six feet. The northern drifts were later widened and extended <br />•i using rubber tired equipment and aze typically nine feet high by twelve feet wide. The Packrat Mine <br />had two ventilation shafts; asixty-inch diameter shaft neaz the end of the northern workings and a <br />thirty-six-inch shaft called Ten Straight near the end of the southern workings. The lazger <br />ventilation shaft was backfilled as part of reclamation, but the Ten Straight is still open and <br />protected by a metal grate. <br />The Packrat Mine operated until 1990 when depressed uranium prices caused it to go on standby. <br />Umetco later reclaimed the mine surface azea in 2002. Energy Fuels reopened the mine in eazly <br />2007 under prospect permit P-2007-003. Under this permit, the road to the Packrat and the main <br />portal were reopened. A small pad azea (less than 0.6 acre) was established in front of the portal. <br />This work was completed in May 2007 and is not shown on Map C-lA. Energy Fuels is currently <br />establishing ventilation and rehabilitating portions of the Packrat Mine so that exploration activities <br />can be safely conducted. <br />.J <br />Whirlwind Mine June 07 D-2 <br />
