BACKGROUND:
ATHA Energy Corp. commenced its 2024 Exploration Program - the Company's most significant exploration program to date and one of the largest uranium focused exploration programs globally - in January of this year. The program targets Canada's most prospective regions for high-grade uranium discovery.
2024 EXPLORATION PROGRAM UPDATE:
Gemini Project 2024 Exploration Program

  * Phase I Geophysics (Complete)
      * Ground Gravity Survey ("GGS") - (Completed February 2024): 92 Energy
        completed a comprehensive GGS focused on the Gemini Mineralized Zone
        ("GMZ") and surrounding area encompassing prospective parallel
        conductors. The results of the GGS were received in late March and
        highlight:
          * The continuation of alteration associated with the GMZ Discovery to
            the southwest within the Gemini Project area.

* The identification of five large-scale gravity anomalies on parallel

            conductors, which are also coincident with EM anomalies and MAG
            lows. These anomalies are high-priority targets.
      * Fleet Space's Exosphere Ambient Noise Tomography ("ANT") - (Completed

April 2024): The ANT system is a non-intrusive, ground-based geophysical survey system designed to measure naturally-occurring seismic vibrations

        in the earth's crust caused by wave action, weather, and other
        anthropogenic activities.
          * Results are pending, however, other ANT surveys completed in the
            Athabasca Basin have been successfully correlated with uranium
            mineralization and associated alteration of the surrounding rock
            mass.
  * Phase II Target Development, Optimization, and Machine Learning (Currently
    Ongoing):
      * Results from Phase I Geophysics, in addition to all data collected
        during previous exploration programs and an ongoing structural study

conducted by SRK Consulting on the controls of uranium mineralization at

        GMZ, will be compiled and utilized to produce a detailed 3D geological
        model of the GMZ. The 3D geological model will be coupled with ATHA's
        proprietary machine learning process to further derisk and advance
        exploration targets at the GMZ and surrounding area prior to
        commencement of Phase III - Diamond Drilling.

Athabasca Basin 2024 Exploration Program

  * Phase I Geophysics (Complete):
      * East Rim Exploration District: Completed Xcite TDEM and Stringer Mag
        surveys on East Vertex, additionally the Company completed a VTEM+
        survey on East Zenith.
      * West Rim Exploration District: Completed a MMT survey across the entire
        district.
  * Phase II Geophysics (Ongoing):
      * North Rim Exploration District: Completed a Gravity Hi-Res Mag survey
        over North Valour, North Beacon, and North Crest. Additionally, the
        Company will commence a MMT survey on North Pinnacle and a QMAGt survey
        on North Summit mid-May.
      * Cable Bay Exploration District: Completed a Gravity Hi-Res Mag survey
        and is currently conducting an ANT survey on the Cable Bay Ridge
        Project.

VANCOUVER, British Columbia, May 15, 2024 (GLOBE NEWSWIRE) -- ATHA Energy Corp. (TSX.V: SASK) (FRA: X5U) (OTCQB: SASKF) ("ATHA" or the "Company"), holder of the
largest uranium exploration portfolio in two of the highest-grade uranium districts in the world, is pleased to provide an update on completed, ongoing, and pending geophysical surveys conducted as part of the Company's 2024
Exploration Program. At the 100%-owned Gemini Project located in the Athabasca Basin, Saskatchewan, the Company completed Phase I Geophysics of its 2024 Gemini
Exploration Program, which consisted of a Ground Gravity Survey ("GGS") and Fleet Space's Exosphere Ambient Noise Tomography (ANT). Both surveys focused on the GMZ, and surrounding area encompassing prospective parallel conductors and aim to identify alterations that may indicate the presence of uranium mineralization. Results from Phase I are being utilized in the currently ongoing
Phase II of the 2024 Gemini Exploration Program, which focuses on data compilation, target development, and optimization. The objective of Phase II is the development of a detailed 3D geological model of the GMZ that will be coupled with ATHA's proprietary machine learning. These processes will further derisk targets, optimize planning and execution during the Company's pending Phase III - Diamond Drill program, commencing in August of 2024.
Additionally, the Company commenced its Athabasca Basin 2024 Exploration Program
in January. The program is comprised of two Phases; Phase I is a continuation of
the Company's maiden 2023 Exploration Program, which covers all of ATHA's Athabasca Basin projects with aerial EM and MAG. The objective of Phase I is to identify high-priority targets that will then undergo additional testing and derisking during Phase II. Phase I was completed during the first half of 2024.
Phase II builds on the results from the maiden 2023 Exploration Program in addition to the results from Phase I. Projects where high-priority targets were identified are undergoing additional testing with geophysical systems such as QMAGt, MMT, Gravity, and ANT survey types. These additional surveys will further
characterize and derisk previously identified high-priority targets and help to identify additional areas of interest. As part of Phase II the Company has completed four surveys across four projects on two of its Exploration Districts.
One survey is ongoing with two additional surveys commencing mid-May. The Company is in the process of analyzing results that will then be evaluated and prioritized for testing during future drill programs.
EXPLORATION OUTLOOK:
The Company's core objective is discovery and development of its portfolio of uranium-focused projects. With the acquisition of Latitude Uranium and 92
Energy, ATHA's portfolio now totals 8.1 million acres across Canada's three most
prospective jurisdictions for uranium discovery and development. The Company's portfolio is highly diversified across the exploration risk curve. With projects
ranging from advanced exploration stage, like Angilak, which hosts the Lac 50
Deposit - one of the largest, highest-grade uranium deposits outside of the Athabasca Basin; to post-discovery projects like Gemini - which contains GMZ, a recent shallow, basement-style, high-grade uranium discovery on the eastern margin of the Athabasca Basin; through to highly prospective greenfields projects with numerous uranium occurrences and high-priority derisked geophysical targets. ATHA's exploration approach is designed to provide maximum exploration exposure by investing at scale in a large number of early-stage projects, derisking those targets, and seeking to deliver advanced exploration upside through the expansion of known uranium deposits and additional discoveries. ATHA's growth strategy is fully funded based on the Company's robust cash position.

Historical Mineral Resource Estimates
All mineral resources estimates presented in this news release are considered to
be "historical estimates" as defined under NI 43-101, and have been derived from
the following (See notes below). In each instance, the historical estimate is reported using the categories of mineral resources and mineral reserves as defined by the CIM Definition Standards for Mineral Reserves, and mineral reserves at that time, and these "historical estimates" are not considered by ATHA to be current. In each instance, the reliability of the historical estimate
is considered reasonable, but a Qualified Person has not done sufficient work to
classify the historical estimate as a current mineral resource, and ATHA is not treating the historical estimate as a current mineral resource. The historical information provides an indication of the exploration potential of the properties but may not be representative of expected results.
Notes on the Historical Mineral Resource Estimate for the Angilak Deposit:
1. This estimate is considered to be a "historical estimate" under NI 43-101
and is not considered by any of to be current. See below for further details regarding the historical mineral resource estimate for the Angilak Property.

     a. Mineral resources which are not mineral reserves do not have
        demonstrated economic viability.

b. The estimate of mineral resources may be materially affected by geology,

        environment, permitting, legal, title, taxation, sociopolitical,
        marketing or other relevant issues.
     c. The quality and grade of the reported inferred resource in this
        estimation are uncertain in nature and there has been insufficient
        exploration to define these inferred resources as an indicated or
        measured mineral resource, and it is uncertain if further exploration
        will result in upgrading them to an indicated or measured resource
        category.
     d. Contained value metals may not add due to rounding.
     e. A 0.2% U3O8 cut-off was used.
     f. The mineral resource estimate contained in this press release is
        considered to be "historical estimates" as defined under NI 43-101 and
        is not considered to be current.
     g. The "historical estimate" is derived from a Technical Report entitled

"Technical Report and Resource Update For The Angilak Property, Kivalliq

        Region, Nunavut, Canada", prepared by Michael Dufresne, M.Sc., P.Geol.
        of APEX Geosciences, Robert Sim, B.Sc., P.Geo. of SIM Geological Inc.
        and Bruce Davis, Ph.D., FAusIMM of BD Resource Consulting Inc., dated
        March 1, 2013 for ValOre Metals Corp.
     h. As disclosed in the above noted technical report, the historical

estimate was prepared under the direction of Robert Sim, P.Geo, with the

        assistance of Dr. Bruce Davis, FAusIMM, and consists of three-
        dimensional block models based on geostatistical applications using
        commercial mine planning software. The project limits area based in the

UTM coordinate system (NAD83 Zone14) using nominal block sizes measuring 5x5x5m at Lac Cinquante and 5x3x3 m (LxWxH) at J4. Grade (assay) and
geological information is derived from work conducted by Kivalliq during

        the 2009, 2010, 2011 and 2012 field seasons. A thorough review of all
        the 2013 resource information and drill data by a Qualified Person,

along with the incorporation of subsequent exploration work and results, which includes some drilling around the edges of the historical resource

        subsequent to the publication of the 2013 technical report, would be
        required in order to verify the Angilak Property historical estimate as
        a current mineral resource.
     i. The historical mineral resource estimate was calculated in accordance

with NI 43-101 and CIM standards at the time of publication and predates

        the current CIM Definition Standards for Mineral Resources and Mineral
        Reserves (May, 2014) and CIM Estimation of Mineral Resources & Mineral
        Reserves Best Practices Guidelines (November, 2019).
     j. A thorough review of all historical data performed by a Qualified
        Person, along with additional exploration work to confirm results would
        be required to produce a current mineral resource estimate prepared in
        accordance with NI 43-101.

2. Notes on the Historical Mineral Resource Estimate for the Moran Lake

    Deposit:
     a. Jeffrey A. Morgan, P.Geo. and Gary H. Giroux, P.Eng. completed a NI
        43-101 technical report titled "Form 43-101F1 Technical Report on the
        Central Mineral Belt (CMB) Uranium Project, Labrador, Canada, Prepared
        for Crosshair Exploration & Mining Corp." and dated July 31, 2008, with
        an updated mineral resource estimate for the Moran Lake C-Zone along
        with initial mineral resources for the Armstrong and Area 1 deposits.

They modelled three packages in the Moran Lake Upper C-Zone (the Upper C

        Main, Upper C Mylonite, and Upper C West), Moran Lake Lower C-Zone, two
        packages in Armstrong (Armstrong Z1 and Armstrong Z3), and Trout Pond.
        These mineral resources are based on 3D block models with ordinary

kriging used to interpolate grades into 10 m x 10 m x 4 m blocks. A cut-

        off grade of 0.015% U3O8 was used for all zones other than the Lower C
        Zone which employed a cut-off grade of 0.035%. A thorough review of all
        historical data performed by a Qualified Person, along with additional
        exploration work to confirm results, would be required to produce a
        current mineral resource estimate prepared in accordance with NI 43-101
        standards.

3. Notes on the Historical Mineral Resource Estimate for the Anna Lake Deposit:

     a. The mineral resource estimate contained in this table is considered to
        be a "historical estimate" as defined under NI 43-101, and is not
        considered to be current and is not being treated as such. A Qualified
        Person has not done sufficient work to classify the historical estimate
        as current mineral resources. A qualified person would need to review
        and verify the scientific information and conduct an analysis and
        reconciliation of historical drill and geological data in order to
        verify the historical estimate as a current mineral resource.

b. Reported by Bayswater Uranium Corporation in a Technical Report entitled

        "Form 43-101 Technical Report on the Anna Lake Uranium Project, Central
        Mineral Belt, Labrador, Canada", prepared by R. Dean Fraser, P.Geo. and
        Gary H. Giroux, P.Eng., dated September 30, 2009.
     c. A 3-dimensional geologic model of the deposit was created for the
        purpose of the resource estimate using the Gemcom/Surpac modeling
        software. A solid model was created using a minimum grade x thickness
        cutoff of 3 meters grading 0.03% U3O8. Intersections not meeting this

cutoff were generally not incorporated into the model. The shell of this

        modeled zone was then used to constrain the mineralization for the
        purpose of the block model. Assay composites 2.5 meters in length that
        honoured the mineralized domains were used to interpolate grades into
        blocks using ordinary kriging. An average specific gravity of 2.93 was
        used to convert volumes to tonnes. The specific gravity data was
        acquired in-house and consisted of an average of seventeen samples
        collected from the mineralised section of the core. The resource was
        classified into Measured, Indicated or Inferred using semi-variogram
        ranges applied to search ellipses. All resources estimated at Anna Lake

fall under the "Inferred" category due to the wide spaced drill density. An exploration program would need to be conducted, including twinning of historical drill holes in order to verify the Anna Lake Project estimate as a current mineral resource.
