Rimrock Exploration & Development, Inc. <br />J-Bird Uranium Mine/ DMO/ EPP Groundwater Quality Data <br />9.0 GROUNDWATERQUALITY DATA <br />Recent drill data and current underground conditions, suggests no groundwater exists <br />within or immediately below the mineralized zone of the formation to be mined. <br />Rimrock has developed a hydrology rationale for DRMS review and approval of drill <br />holes for groundwater presence or absence (Section 8 - Groundwater Information). <br />DRMS will require monitoring of groundwater presence or absence to adequately <br />determine baseline conditions. As directed by DBMS, in previous communication dated <br />September 23, 2008 regarding the Liberty Mine NOI Mod #2 (paragraph C), five (5) <br />quarters of data are required. "If no water is encountered initially, then a piezometer <br />should be constructed to gather the required five quarters of data. If ground water is <br />detected in measurable amounts then the piezometers may need to be pulled and water <br />quality monitor wells constructed. . . .Construction details such as screen intervals, <br />general equipment installation requirements, etc., will need to be reviewed by the <br />Division if BlueRock intends to construct the wells." <br />If groundwater of significant presence (>I gpm) is measured for two consecutive quarters, <br />SPLP parameter analysis for five quarters using a state certified laboratory will be <br />performed identifying the following (seeAttachment D <br />Table 1 <br />DRMS Recommended Water Ouality /Geochemical Analvtes <br />Field pH Nickel Ammonia <br />Electrical Conductivity Nitrate + Nitrite Antimony <br />Aluminum Selenium Beryllium <br />Arsenic Sulfate Chromium <br />Barium Uranium Chloride <br />Cadmium Vanadium Fluoride <br />Copper Zinc Manganese <br />Iron Gross Alpha Mercury <br />Lead Silver <br />Molybdenum Thallium <br />15
