The acquired property interests fit well with Ur-Energy's corporate strategy of expanding the resource base available for processing at the Lost Creek facility while the database will be useful to Uranium One with respect to its Allemand-Ross project in Wyoming's Powder River Basin. The Property Interests The Property Interests being conveyed to Ur-Energy are contiguous with the southeast, north and southwest boundaries of the Company's Lost Creek Project which is licensed by the US Nuclear Regulatory Commission ("US NRC") and permitted with the Wyoming Department of Environmental Quality. The Property Interests comprise two Wyoming State Mineral Leases and one hundred seventy-five federal mining claims, collectively totalling approximately 5,250 acres (2,124 hectares). Combined with the Company's current property holdings, the Lost Creek Property will include over 39,000 contiguous acres (15,783 hectares) when the transaction is completed. In addition, Uranium One will provide certain geologic data files related to the area in which the State Mineral Leases and federal mining claims are located. Prior to entering into this Agreement, Ur-Energy already possessed a database containing approximately 1,000 historic drill holes within the area of the Property Interests. Ur-Energy's technical team plans to use the available historic drill data to determine a resource for the newly acquired Property Interests and expects to incorporate those resources into an updated NI 43-101 report for the Lost Creek Property. The Database In consideration for the Property Interests, Uranium One will acquire a geologic database containing over 3,000 unique drill hole logs, greater than 200 report maps, cross-sections and reports covering an area of interest in Converse County, Wyoming that includes Uranium One's Allemand-Ross project. About Ur-Energy Ur-Energy is a junior uranium company currently completing mine planning and permitting activities to bring its Lost Creek Wyoming uranium deposit into production.
