(WWL), on behalf of Western Uranium Corporation (WUC), has <br /> prepared this letter as a formal submittal of baseline hydrochemical data collected at monitoring wells <br /> installed at the Sunday Mine Complex located in western Montrose County, Colorado. The Sunday <br /> Mine Complex consists of five uranium mines located on the west flank of Disappointment Valley. <br /> DRMS permit numbers consist of the following: <br /> Sunday Mine:M-1977-285 <br /> Carnation Mine:M-1977-416 <br /> St.Jude Mine:M-1978-039HR <br /> Topaz Mine:M-1980-055 HR <br /> West Sunday Mine:M-1981-021 <br /> These data fulfill a data request requirement by Colorado Division of Reclamation,Mining, and Safety <br /> (DRMS). <br /> Background <br /> Groundwater monitoring program at the Sunday Mine Complex was initiated by Energy Fuels <br /> Resources (USA) Inc. (EFR) in 2013 as a result of discussions with DRMS and the U.S. Bureau of <br /> Land Management(BLM). The purpose of the monitoring program was to fulfill a five-quarter water <br /> quality baseline investigation per DRMS'request,and to acquire information that would lead to a better <br /> understanding of the hydrogeology of the mine complex and vicinity. Pinon Ridge Mining LLC <br /> acquired the Sunday Mines Complex from EFR in August,2014. <br /> WWL understands that EFR, DRMS, and BLM agreed to the installation of several groundwater <br /> monitoring wells that would be used to assess and investigate hydrogeological conditions in the vicinity <br /> of the mine complex and provide chemistry data per DRMS' request. Four monitoring wells were <br /> constructed; MW-Sun1, MW-Sun2, MW-Sun3, and MW-TPZ. EFR, DRMS and BLM discussed the <br /> potential need for two additional wells if it was found that information from initial phase of well <br /> installation was insufficient to adequately understand site hydrogeologic conditions. <br /> Applications in Earth Science 743 Horizon Court Suite 330,Grand Junction,CO 81506 <br /> Phone:(970)242-0170 Fax:(970)242-0270 <br />
