INTRODUCTION This report describes the installation, development, and hydraulic testing of perched monitoring wells MW-38, MW-39 and MW-40 at the White Mesa Uranium Mill (the “Mill” or the “site”) near Blanding, Utah. The three wells were installed far to the southeast of the tailings management system as shown on Figure 1. All three wells were installed as required by the January 19, 2018 Groundwater Discharge Permit. These wells are located far to the southeast (cross-gradient) of the tailings management system. All three wells were installed during the week of February 12, 2018. Development consisted of surging and bailing (during February and March, 2018) followed by overpumping (during March, 2018). Hydraulic testing consisted of slug tests conducted during the week of March 19, 2018.

DRILLING AND CONSTRUCTION Well installation procedures were similar to those used previously at the site for the construction of other perched zone wells (Hydro Geo Chem, Inc. [HGC], 2005). Drilling and construction were performed by UCOLO Drilling, LLC, and borings logged by Mr. Lawrence Casebolt under contract to Energy Fuels (USA) Corporation (EFRI). As-built diagrams for the well construction, based primarily on information provided by Mr. Casebolt, are shown in Figures 2 through 4. The depths to water shown in the as-built diagrams were based on water level measurements taken just prior to development (in feet below land surface). New wells were surveyed by a State of Utah licensed surveyor and the location and elevation data are provided in Table 1. 2.1 Drilling and Logging Procedures All borings were drilled by air rotary using tricone bits. Drill cuttings samples for all borings were collected at 2½-foot depth intervals and placed in labeled, zip-sealed plastic bags and labeled plastic cuttings storage boxes Copies of the lithologic logs submitted by Mr. Casebolt are provided in Appendix A. For each well an 11-inch diameter tricone bit was used to construct borings of sufficient diameter to install 8-inch-diameter, Schedule 80 poly vinyl chloride (PVC) surface (conductor) casings. The surface casings extended to depths of approximately 9 feet below land surface. Once the surface casings were in place, the boreholes were drilled by air rotary (and foam as needed) using a 6¾ inch diameter tricone bit. The boreholes penetrated the Dakota Sandstone and the Burro Canyon Formation and terminated in the Brushy Basin Member of the Morrison Formation. Although not specifically noted in the lithologic log, drilling fluid return from the lowermost portion of the MW-39 borehole (near the contact between the Burro Canyon Formation and underlying Brushy Basin Member) had a reddish color and sheen. This color change may be due to the change in color from the light-colored sandstone of the Burro Canyon Formation to the purplish-brown to red shale within the uppermost portion of the Brushy Basin Member; however, both the color and sheen may also indicate the presence of iron bacteria. If present in the formation, iron bacteria are expected to influence the chemistry of the perched groundwater collected from this well. Pyrite in the MW-39 borehole was also noted at the contact between the Burro Canyon Formation and underlying Brushy Basin Member (as noted in the lithologic log) and is also Installation and Hydraulic Testing of Perched Monitoring Wells MW-38, MW-39 and MW-40, White Mesa Uranium Mill (As-Built Report) H:\718000\MW38_39_40\report\MW38_39_40_instal_final.doc June 12, 2018 4 expected to impact the chemistry of the perched groundwater collected from this well. The influence of pyrite in the perched groundwater zone is discussed in HGC (2012). 2.2 Construction The wells were constructed using 4-inch diameter, Schedule 40, flush-threaded PVC casing and 0.02-slot, factory-slotted PVC screen. Colorado Silica Sand was used as a filter pack and installed to depths of approximately 4 to 6 feet above the screened intervals. The annular spaces above each filter pack were sealed with hydrated bentonite chips. Well casings were fitted with 4-inch PVC caps to keep foreign objects out of the wells and lockable steel security casings were installed to protect the wells. 2.3 Development Wells were developed by surging and bailing followed by overpumping. Development records are provided in Appendix B.

HYDRAULIC TESTING Hydraulic testing consisted of slug tests conducted by HGC personnel using a methodology similar to that described in HGC (2005). 3.1 Testing Procedures The 3-foot long slug used for the tests in MW-39 and MW-40, which displaced approximately 3/4 gallons of water, is described in HGC (2002). Due to the small saturated thickness at MW-38, a shorter (approximately 1 ½ foot long) slug displacing approximately 0.36 gallons, was used for the test at that well. Both slugs consisted of sealed, pea-gravel-filled PVC pipe; the 3-foot long slug used schedule 80 PVC and the 1 ½ foot long slug used schedule 40 PVC. Level TrollTM 0-30 pounds per square inch absolute (psia) data loggers were used for the tests. The Level Trolls were deployed below the static water column of the tested wells and used to measure the change in water level during the test. A 0-30 psia Baro-TrollJ was used to measure barometric pressure and was placed in a protected environment near the wells for the duration of the testing. Automatically logged water level data were collected at 3-second intervals and barometric data at 5-minute intervals. Prior to each test, the static water level was measured by hand using an electric water level meter and recorded in the field notebook. The data loggers were then lowered to a depth of approximately ten feet below the static water level in each well except MW-38. Because the water column height in MW-38 was only approximately 6 feet, the logger was lowered to the base of the well casing. Background pressure readings were then collected for approximately 1 to 3 hours prior to beginning each test. The purpose of collecting the background data was to allow correction for any detected water level trends. Once background data were collected, the slug and electric water level meter sensor were suspended in the tested well just above the static water level. Each test commenced by lowering the slug to a depth of approximately two feet below the static water level over a period of a few seconds and taking water level readings by hand as soon as possible afterwards. Hand-collected data recorded in the field notebook were obtained more frequently in the first few minutes when water levels were changing more rapidly, then less frequently as the rate of water level change diminished. Upon completion of each test, automatically logged data were checked and backed up on the hard drive of a laptop computer. Installation and Hydraulic Testing of Perched Monitoring Wells MW-38, MW-39 and MW-40, White Mesa Uranium Mill (As-Built Report) H:\718000\MW38_39_40\report\MW38_39_40_instal_final.doc June 12, 2018 6 3.2 Hydraulic Test Data Analysis Data from each test was analyzed using AQTESOLVETM (HydroSOLVE, 2000), a computer program developed and marketed by HydroSOLVE, Inc. In preparing the automatically logged data for analysis, the raw data were converted to displacements and the total number of records was reduced. All data collected in the first 30 seconds (except for a negative displacement caused by initial water level oscillation) were retained, then every 2nd, then 3rd, then 4th, etc. record was retained for analysis. For example, if the first 10 records were retained (30 seconds of data at 3-second intervals), the next records to be retained would be the 12th, the 15th, the 19th, the 24th, etc. Data were analyzed using two solution methods: the KGS unconfined method (Hyder et al., 1994) and the Bouwer-Rice unconfined method (Bouwer and Rice, 1976). When filter pack porosities were required by the analytical method, a value of 30 percent was used. The saturated thicknesses were taken to be the difference between the depth of the static water level measured just prior to each test and the depth to the Brushy Basin Member contact as defined in the drilling logs (Appendix A). The static water levels were below the tops of the screened intervals in all three wells and the saturated thicknesses were taken to be the effective screen lengths. An increase in barometric pressure during the test at MW-39 appeared to influence the automatically-logged data, and the displacements calculated from that data were corrected accordingly. Figure 5 compares corrected and uncorrected water level displacements for automatically logged data at MW-39. Corrections did not need to be applied to displacements at MW-38 and MW-40. The KGS solution allows estimation of both specific storage and hydraulic conductivity, while the Bouwer-Rice solution allows estimation of only the hydraulic conductivity. The Bouwer- Rice solution is valid only when a straight line is identifiable on a plot of the log of displacement versus time (indicating that flow is nearly steady), and is insensitive to both storage and the specified initial water level rise. Generally, only the later time data are interpretable using Bouwer-Rice. In analyzing data from MW-40, near-straight line portions of middle and late-time data were both analyzed. The KGS solution accounts for non-steady flow and storage, is sensitive to the specified initial water level rise, and generally allows a fit to both early- and late-time data. Both KGS and Bouwer-Rice solutions were used for comparison. Automatically logged and hand-collected data were analyzed separately using both solution methods. The hand-collected data therefore served as an independent data set and a check on the accuracy of the automatically logged data.

Appendix C contains plots generated by AQTESOLVETM that show the quality of fit between measured and simulated displacements, and reproduce the parameters used in each analysis. Appendix D provides both raw and corrected displacement data. Estimates of hydraulic conductivity range from approximately 1.8 x 10-5 centimeters per second (cm/s) to 1.3 x 10-4 cm/s using automatically logged data, and from approximately 1.4 x 10-5 cm/s to 2.1 x 10-4 cm/s using hand-collected data. Estimates are within the middle portion of the range previously measured at the site (approximately 2 x 10-8 cm/s to 0.01 cm/s). In general, there is good agreement between estimates obtained from the two solution methods and between estimates obtained from automatically logged and hand-collected data. All estimates are within a factor of two, except for the late-time Bouwer-Rice estimate for MW-40, which was a factor of 3 lower than the highest estimate for that well (using automatically logged data). Although there was generally good agreement between the KGS and Bouwer-Rice results, because the KGS solution accounts for non-steady flow and aquifer storage, the results obtained using KGS are considered more representative than those obtained using Bouwer-Rice.

CONCLUSIONS Procedures for the installation, hydraulic testing, and development at new perched monitoring wells MW-38, MW-39 and MW-40 are generally similar to those used previously at the site for the construction, testing, and development of other perched zone wells.
