Global Atomic Corporation reported assay results from four holes drilled in 2018 at its DASA project, Republic of Niger. All four holes have returned substantially higher assay grades than previously reported probe results. Highlights: Significant high grade intersection of 17,118 ppm U3O8 (1.71%) returned over 98 meters ("m") in ASDH563, 135% higher than the previous probe-only estimate of 7,277 ppm eU3O8; Laboratory assay limit of 17.62% U3O8 exceeded over an interval of 3.5m from 235.5m to 239.0m in ASDH563; ASDH543 intersected 6,919 ppm (0.69%) U3O8 over 75m, approximately 37% higher than the prior probe estimate of 5,041 ppm eU3O8; These assay results indicate the probe underestimated previously released DASA drill results. Based on existing probe data, knew that DASA was a significant uranium deposit, however, the grades and widths reported here will enhance the resource figures already announced and will calculate an updated Mineral Resource Estimate as soon as all assays are received from the 2018 drill program. Uranium resource estimates are typically calculated using data from downhole probes that use a scintillometer to measure radioactivity. Probes are carefully calibrated against known, standard holes. For the drilling in 2018 Global Atomic used probes calibrated both against standard holes in Bessines, France and in Arlit, Niger. The DASA resource update published in July 2018 used the historic database of results, plus probe data from 36 of the 58 holes drilled. Chemical assay data allows a further calibration on the dataset. For the 58 holes drilled by Global Atomic in 2018, XRF analysis at ALS Global Vancouver is currently underway. Results for the first four holes have been released, and are shown below. The assay data from the remaining 54 holes is expected in the coming weeks. Once all assay and probe data is returned, a final correlation coefficient (the K-factor) can be calculated. A Mineral Resource Estimate updated to include all 58 holes drilled in 2018, with a new K-factor applied to results, will be released in first half of 2019. Global Atomic uses the industry convention to report estimate grades ("eU3O8") until the data set is updated with assay results and a new K-factor calculation applied, when grades can be reported as U3O8. Results received from four holes ASDH538, ASDH541, ASDH543, and ASDH563 show consistently higher grades than the probe results previously reported. ASDH538 returned 95.2 meters ("m") at 5,451 ppm (0.55%) U3O8 which is approximately 23% higher than the previous probe- only estimate. ASDH541 returned 44.3m at 7,286 ppm (0.73%) U3O8 grading 9% higher than the prior probe estimate and ASDH543 returned 75.0m, grading 6,919 ppm (0.69%) U3O8 approximately 37% higher than the prior probe estimate. ASDH563 returned a 98.0m intersection, at 17,118 ppm (1.71%) U3O8 significantly higher than the previous probe-only estimate recorded over an interval of 107.3m. Grade intervals established from assaying are definitive. Within drill hole ASDH563 a 3.5m interval from 235.5m to 239.0m exceeded ALS Labs assay limit of 17.62% U3O8 and further steps are being taken to determine the grade of these samples. The company has implemented a quality assurance and control programme to ensure sampling and analysis of exploration work is conducted in accordance with industry standards. Drill core is pulverized and split in Niamey, Niger. The pulps are then sent to ALS laboratories in Vancouver for 36 element ICP and XRF assaying. Certified reference standards and blanks are inserted into the sample stream on a regular interval basis and monitored as part of the QA/QC program.
