Global Atomic Updates Dasa's Mineral Resource Estimate

Significant Conversion of Inferred to Indicated Expected to Impact Mineable Reserves

TORONTO, May 23, 2023 /CNW/ - Global Atomic Corporation ("Global Atomic" or the "Company"), (TSX: GLO) (OTCQX: GLATF) (FRANKFURT: G12) announced today that the Company has updated its Mineral Resource Estimate ("MRE") for its Dasa Project in the Republic of Niger.

The new MRE was calculated by AMC Consultants, ("AMC"), of Perth, Western Australia, incorporating drill, probe and chemical assay data compiled from an extensive 16,000-meter drill program initiated in September 2021, that focused on infill drilling to upgrade Inferred Resources to the higher resource classification of Indicated, which allows these resources to be included in an updated Mine Plan and Mineral Reserve.

In addition, all geotechnical data derived from drill core was incorporated. The geological model of the Dasa Deposit continues to demonstrate excellent continuity and the next phase of drilling in now being planned.

It is important to note that unlike the 2019 MRE the new MRE is focused solely on an Underground Mine Model and does not include open pit modelling of near surface mineralization. As shown in Table 2 below, this had the effect of increasing tonnage with varying impact on grade depending upon the applied cut-off grade.

Global Atomic President and CEO, Stephen G. Roman commented, "The results of the drill program were successful in significantly increasing Dasa's Indicated Resources, much of which is expected to be upgraded to a Mineable Reserve when included in the planned revision to Dasa's Mine Plan and Updated Feasibility Study.  The drilling also gave us a big boost in additional Inferred Resources with excellent grades that will be the target for further drilling."

"The Company intends to update the Dasa mine plan and Feasibility Study by the end of this year, using the new MRE as well as actual costs for mining and capital costs for the processing plant.   As the current Feasibility Study is based on a US$35/lb uranium sale price and spot prices are now above US$50/lb, there will be an opportunity to lower the cut-off grade, increase the mineable reserves and improve Dasa Project economics."

In the following table, the Indicated Resource using a cut-off grade of 1,500 ppm eU₃O₈, has increased by 50%, showing an excellent conversion factor from Inferred.

Based on Dasa's previous MRE, that was effective as of June 1, 2019, the Company identified specific areas of Indicated Resources and significant areas of Inferred Resources, particularly in the lower left-hand side of Figure 1 below and between Zones 2 and 3.   This information guided the location of infill drilling as part of the 16,000-meter drill program.  

Drill cores from the program were assayed at ALS Labs in Vancouver, Canada, by wavelength dispersion X-Ray Fluorescence Spectrometry for Uranium on pressed powder pellet for all the samples then on disc (pulp sample + lithium borate flux; mixture fused at 1050 – 1100°C) for all samples grading above 1,500 ppm.

The assaying carried out by ALS and the high-grade samples above 12% uranium content by SGS Lakefield laboratory were validated and used to calculate a new Gamma Probe / Assay correlation line. The newly derived equivalent grades were used for the 2023 MRE.   Figure 2 shows a significant conversion of Inferred to Indicated Resources and the potential for an expansion of Dasa's Mineral Reserve.

About Global Atomic

Global Atomic Corporation (www.globalatomiccorp.com) is a publicly listed company that provides a unique combination of high-grade uranium mine development and cash-flowing zinc concentrate production.

The Company's Uranium Division includes four deposits with the flagship project being the large, high-grade Dasa Project, discovered in 2010 by Global Atomic geologists through grassroots field exploration. With the issuance of the Dasa Mining Permit and an Environmental Compliance Certificate by the Republic of Niger, the Dasa Project is fully permitted for commercial production. The Phase 1 Feasibility Study for Dasa was filed in December 2021 and estimates yellowcake delivery to utilities to commence in 2025. Mine excavation began in Q1 2022.

Global Atomic's Base Metals Division holds a 49% interest in the Befesa Silvermet Turkey, S.L. (BST) Joint Venture, which operates a modern zinc production plant, located in Iskenderun, Türkiye. The plant recovers zinc from Electric Arc Furnace Dust (EAFD) to produce a high-grade zinc oxide concentrate which is sold to zinc smelters around the world. The Company's joint venture partner, Befesa Zinc S.A.U. (Befesa) holds a 51% interest in and is the operator of the BST Joint Venture. Befesa is a market leader in EAFD recycling, with approximately 50% of the European EAFD market and facilities located throughout Europe, Asia and the United States of America.
