ATHA ENERGY PROVIDES UPDATE ON 2024 EXPLORATION PROGRAM

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)

o 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 f ive large -scale gravity anomalies on parallel conductors,

which are also coincident with EM anomalies and MAG lows. These anomalies are

high-priority targets.

o 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):

o 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):

o East Rim Exploration District: Completed Xcite TDEM and Stringer Mag surveys on East

Vertex, additionally the Company completed a VTEM+ survey on East Zenith.

o West Rim Exploration District: Completed a MMT survey across the entire district.

• Phase II Geophysics (Ongoing):

o 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.

o 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 – 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 conductor s 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 focus es on data compilation, t arget

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 exposur e 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 rel iability 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 th e

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 informati on

and conduct an analysis and reconciliation of historical drill and geological data in order to verify the historical estimat e 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 fr om 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.
