Ur-Energy Delineates Deeper Resources at Lost Creek
Littleton, Colorado (Marketwire – January 6, 2011) Ur-Energy Inc. (TSX:URE, NYSE Amex:URG) (“Ur-Energy” or the “Company”) announces completion of a 2.5 month drilling campaign on its Lost Creek permit area in the Great Divide Basin, Wyoming. This drilling campaign accomplished several goals, the most significant of which was the delineation of deeper resources in the KM stratigraphic horizon of the Lost Creek deposit, which lie below Mine Unit #1 resources contained in the HJ stratigraphic horizon. The Lost Creek permit area is currently in the advanced stages of obtaining permits to mine uranium by means of In-situ Recovery (ISR) from the HJ stratigraphic horizon.
Earlier in 2010, a separate drilling program focused on delineating a second well field (Mine Unit #2) in the HJ horizon (Ur-Energy Press Release dated March 17, 2010). Delineation drilling for the first well field (Mine Unit #1) was completed in 2008.
The latest 2010 activities at Lost Creek were aimed at advancing the permitting process. A total of 39,061 feet (11,905 m) of drilling was completed with four rotary drill rigs. This recent drilling program accomplished the following: 45 drill holes to complete delineation of resources within the KM horizon beneath Mine Unit #1; improvements to 19 monitoring wells; installation of 2 new monitoring wells; and 6 wide-spaced exploration holes to test deeper horizons.
Mine Unit #1 is currently being permitted to recover uranium only within the HJ stratigraphic horizon, a unit that starts at about 325 feet (99 m) deep. Resources within the underlying KM stratigraphic horizon, with the top of the horizon at about 475 feet (145 m) deep, will be permitted and mined as a separate future mine unit. Because some resources within the KM horizon underly Mine Unit # 1 they required delineation before mining Mine Unit #1. Mineral intercepts averaged 14.1 feet (4.3 m) of 0.049% eU3O8.
Recompletion work-overs were conducted on 19 monitoring wells, 18 of which are within Mine Unit #1. This was carried out at the request of the Wyoming Department of Environmental Quality (WDEQ) in conjunction with their review of Ur-Energy’s application for the Permit to Mine which will include Mine Unit #1. The drilling also included the installation of two new observation monitor wells. This concludes the pre-mining installation of regional and Mine Unit #1 monitoring wells that will be used for operational monitoring. There are now a total of 157 installed monitoring and baseline wells within the Lost Creek permit area.
Six deep, wide-spaced exploration holes were drilled in the southwest area of the property which is approximately 1 to 1½ miles (1.6-2.4 km) south of the main ore trend. Drilling depths were to 1200 feet (366 m). These holes were intended to test for potential roll fronts in the HJ, KM, and deeper
