Domestic Projects
Ur Energy, Inc. Project
 Ur-Energy USA, Inc. is in the process of developing the Great Divide Basin In Situ Leaching (ISL) Uranium Project, Sweetwater County, Wyoming. The Ur-Energy Great Divide Basin project includes two claim areas: the Lost Soldier claim area and the Lost Creek claim area. The Lost Soldier claim area is located approximately three miles west of the town of Bairoil, WY. The Lost Creek claim area is 10 miles southwest of the Lost Soldier claim area. An NI 43-101 study of the Lost Soldier project states that Roscoe Postle Associates considers the relevant historic resources on the project to consist of 6.2 million pounds of Demonstrated Resource and 3.8 million pounds of Inferred Resource at an average eU3O8 grade of 0.16%. An NI 43-101 study of the Lost Creek project states that Roscoe Postle Associates considers the relevant historic resources on the project to consist of 5.7 million pounds of resource at an average eU3O8 grade of 0.062%.
Tar Creek Superfund Project
 AATA provided project technical support to complete a full Remedial Investigation/Feasibility Study (RI/FS) for the 40 square mile Tar Creek Superfund Site, Rural Operable Unit #4. AATA conducted extensive characterization studies of chat, flotation tailings, and other mine residues over the large historical lead/zinc mining area in NE Oklahoma, in support of Blue T Corp, the USEPA, Oklahoma DEQ, and other agencies.
Betze Seeps and Springs Project
 The Betze-Post Mine, operated by Barrick Goldstrike Mines Inc. (BGMI), is located approximately 27 miles northwest of Carlin, Nevada, USA. Mining operations require that groundwater be removed to main a dry and safe working environment for the pit and underground workings. Dewatering program began in 1988 when mine operations first encountered the groundwater table. Under the agreement with the Bureau of Land Management ( BLM), Barrick initiated the annual seep and spring monitoring program in 1989. The study consists of evaluating water chemistry and measuring flow rates, as well as collecting vegetation data sets at designated sites. A total of 35 sampling sites in nine drainage systems (catchments) were selected in the project area, covering over 450 square miles and crossing three counties (Elko, Lander, and Eureka) in the state of Nevada. Plate 1 shows the topography and locations of monitoring sites in the study area. The monitoring sites are subdivided into two groups based on their geographic locations and the starting time of the monitoring program. The East Seeps and Springs, located in the Tuscarora Range, were first sampled in 1989; while the West Seeps and Springs in the Sheep Creek Range were first sampled in 1995. Tables 1.1a and 1.1b present a summary on each monitoring.
