Global Atomic Announces Significant Resource Upgrade at DASA Project
TORONTO, July 18, 2019 - Global Atomic Corp. (“Global Atomic” or the “Company”) is pleased to announce the results of the new Mineral Resource Estimate (“MRE”), calculated by CSA Global Pty. Ltd.,(“CSA Global”), of Perth, Western Australia, incorporating drill, probe and chemical assay data compiled from work programs on the DASA Project during 2017, 2018 and 2019. In addition, all geotechnical data derived from drill core was incorporated, which has clearly defined the structure and stratigraphic boundaries of the Block Model.
Highlights:
- Indicated Resource Increases by 56% to 101.6 million pounds eU3O8 at 1,752ppm
- Inferred Resource Increases by 81% to 87.6 million pounds eU3O8 at 1,781ppm
- Using a 1,200 ppm cut-off, the grade/tonnage report estimates 78.0 million pounds eU3O8 at 4,483ppm in the Indicated Category, an increase of 30% over the previous report
- Using a 1,200 ppm cut-off, the grade/tonnage report estimates 69.9 million pounds eU3O8 at 3,783ppm in the Inferred Category, an increase of 45% over the previous report
- The DASA Deposit remains open along strike and down dip and further expansion drilling is recommended by CSA Global

Stephen G. Roman, President and CEO, commented, “The update completed by CSA Global further confirms the robust nature of DASA. The resource is shown to contain over 100 million pounds Indicated and 87 Mlbs of Inferred Resources, and the deposit remains open for further resource expansion. Our current focus is on the rapid advancement of the project towards production. Global Atomic is commissioning CSA Global to carry out a study for an open pit at DASA, and the Company continues to discuss development options with Orano Mining SA.”
Mineral Resource Estimate
In December 2018, CSA Global was commissioned by Global Atomic to provide an updated NI 43-101 compliant Mineral Resource Estimate and PEA for the DASA Project, located in the Tim Mersoi Basin, Republic of Niger, West Africa.
The current Mineral Resource Estimate incorporates data from twenty-three additional holes that were not included in the December 2018 resource, plus chemical assay data from the diamond drilling program carried out 2017 to 2018. In addition, lithology and structural data derived from drill core was used to build a definitive geological model for the deposit. The additional data has enhanced the understanding and definition of the structural and stratigraphic boundaries of the resource, and accordingly a new Geological Model and a new Block Model have been generated.
Global Atomic has been investigating the DASA project since its discovery in 2010, and has undertaken multiple phases of exploration and evaluation programs. These programs have included; exploration and resource evaluation drill programs, mapping, geophysical investigations, downhole geophysical logging, geotechnical analysis of drill core, metallurgical sampling and analysis, hydrological studies and base line environmental work.
The DASA Project is 100% owned by Global Atomic and forms part of a larger 750km² package of six permits comprising three additional deposits.
Pit Optimization
As part of this MRE, CSA Global completed a conceptual pit optimization study based on the updated block model. The mineral resource above a 320 ppm cut-off was reported within the constraining conceptual optimized pit. The material outside of the pit-constrained resources was considered for extraction by underground mining methods and was reported at a higher cut-off of 1,200 ppm. Table 2 contains examples of tonnages and grades at varying cut-off values within the resource model.
Grade Tonnage Report
The overall unconstrained resources have increased at the DASA deposit reflecting improved geological understanding and confidence in the continuity of mineralisation. Equally important is that the MRE uses a 320 ppm cutoff for open pit and 1,200 ppm for underground. Higher cut-offs can be utilized to mine higher grade ores during periods of low uranium prices. See Table 2 below.

Further Work
Global Atomic is planning more detailed work with CSA Global on the Indicated Resources suitable for open pit mining, and on the Inferred Resources at depth which are more suited to underground mining. An announcement will be made once the scope and parameters of the studies are finalized. In parallel, the Company continues to discuss development options with Orano Mining.

Global Atomic Corp. is a TSX listed company providing a unique combination of high-grade uranium development and cash flowing zinc concentrate production.
The Company’s Uranium Division includes six exploration permits in the Republic of Niger covering an area of approximately 750 km². Uranium mineralization has been identified on each of the permits, with the most significant discovery being the DASA deposit situated on the Adrar Emoles III concession, discovered in 2010 by Global Atomic geologists through grassroots field exploration. The DASA deposit is currently undergoing a feasibility program to study a number of operating scenarios, including the option to ship mineralized material to Orano Mining’s operations in Arlit under an MOU signed with Orano in July, 2017.
Global Atomics’ Base Metals Division holds a 49% interest in Befesa Silvermet Turkey, S.L. (“BST”) joint venture, which operates a processing facility, located in Iskenderun, Turkey, that converts Electric Arc Furnace Dust (“EAFD”) into 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”, listed on the Frankfurt exchange under ‘BFSA’), holds a 51% interest in and is the operator of the BST joint venture. Befesa is a market leader in EAFD recycling, capturing approximately 50% of the European EAFD market with facilities located throughout Europe and Korea.
BST is well underway with an expansion project to significantly modernize and expand its processing plant in Turkey. The expansion is targeted to double annual production of zinc from 30 million lbs to 60 million lbs and is supported by EAFD supply currently available for processing in Turkey. The new plant is scheduled for completion by September 2019.
