Drill Results Exploration Programs

ATHA ENERGY COMPLETES MAIDEN EXPLORATION PROGRAM AT

THE ANGILAK PROJECT IDENTIFIES MULTIPLE NEW MINERALIZED

TRENDS AND EXPANDS URANIUM MINERALIZATION AT LAC 50

HIGHLIGHTS:

● The Angilak Project is host to the Lac 50 Uranium Deposit (the “Lac 50 Trend”), one of the largest

high-grade deposits outside of the Athabasca Basin, with a historical mineral resource estimate

of 43.3M lbs at an average grade of 0.69% U 3O8.1 Drilling conducted by Latitude Uranium at the

Angilak Project in 2023 intersected grades of up to 7.54 % U3O8 over 1.6 m.

● The 2024 Angilak Exploration Program has concluded after twenty-five diamond drill holes were

completed between early June and late August for a total of ~10,051 m. The program was highly

successful and on budget.

● All objectives were successfully achieved with the expansion of the historic footprint of

mineralization along the Lac 50 Trend and the identification of new parallel mineralized trends

called the Lac 48, Lac 52, and Lac 54 Trends.

● The Lac 48, Lac 50 (host to the historic Lac 50 Deposit), Lac 52, and Lac 54 Trends remain open in

all directions with high prospectivity for further discovery and expansion of uranium

mineralization. Additionally, untested areas between the newly identified trends are also

prospective for discovery of new mineralized trends.

● Regional Exploration at Angilak: Thirteen holes were completed at prospective regional targets

proximal to the Lac 50 Trend for a total of 5,167 m.

▪ All holes discovered new lenses of uranium mineralization, expanded on previously

discovered showings, or identified prospective structures. Three prospective trends – all

parallel to the Lac 50 Trend – were tested:

1. Lac 48 Trend – located ~1 km to the southwest of the Western-Extension Zone at

Lac 50. One hole was drilled during 2024 at the Blaze target and intersected high-

grade mineralization with a peak of 10,642 cps at 94.9 m depth. The Lac 48 Trend

consists of several parallel mineralized corridors with approximate strike lengths

of 500 to 1,100 m (Figure 2a).

2. Lac 52 Trend – located ~750 m to the north of the Main Zone at Lac 50. A total of

eight holes were drilled during 2024 along the 5.2 km long corridor within the

Pulse and Mushroom Lake Target areas. Drilling along the Lac 52 Trend is

highlighted by holes:

▪ PL-DD-030: intersected high -grade mineralization between 262.4 and

262.7 m with a peak of 30,273.4 cps recorded via gamma probe.

▪ ML-DD-009: intersected high -grade mineralization with a peak of

14,870.5 cps at 102.7 m depth.

3. Lac 54 Trend – located ~1.5 km to the north of the J4/Ray Zones. A total of four

holes were drilled during 2024, all intersecting uranium mineralization, extending

the mineralized strike length to ~1.1 km.

● Mineral Expansion at the Lac 50 Deposit – Twelve holes were drilled, targeting expansion of

uranium mineralization beyond the modeled grade shells from the 2013 historic resource , for a

total of 4,884 m.

▪ All holes achieved the objectiv e of intersecting uranium mineralization outside of the

historic mineralized domains and expanding the footprint of mineralization of the known

zones, along with identification of new tuff horizons.

1. Jay4/Ray Zones – A total of five holes were drilled during 2024, all successfully

intersecting uranium mineralization . Importantly, mineralization intersected

approximately 400 m along strike to the west of the J4/Ray Zones extends the

prospective mineralized strike length to ~1.8 km.

2. Western-Extension, Main Zone, and Eastern -Extension – A total of eight holes

were drilled, all intersecting uranium mineralization , expanding on known zones

of mineralization and identifying new tuff horizons. Importantly, as more drilling

along the trend occurs , the Company continues to clarify the lithological and

structural controls on mineralization demonstrating continuity between the

historic mineralized domains . The footprint of m ineralization extends along the

Lac 50 Trend over a strike length of ~3.9 km.

● Radioactivity results from the first six drill holes can be found here. Details on the remaining

nineteen drill holes, including strip logs, can be found here.

● Phase II (geophysics & ground geochemistry): Commenced at the Angilak Project in early August

and is c omprised of airborne geophysics consisting of electromagnetic (“ EM”), mag, and VLF

survey types, in addition to targeted ground geochemistry sampling and mapping . The program

is expected to be completed by mid-September.

Vancouver, British Columbia, September 3, 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 district s in the world, is pleased to announce the completion of its 2024

Exploration Program at its 100% -owned Angilak Project in Nunavut. During Phase I : diamond drilling,

which began in early June and continued through to late August , the Company completed twenty-five

diamond drill holes for a total of ~10,051 m. Drilling targeted expansion along the Lac 50 Trend, as well as

discovery and expansion along several regional targets, identified as the Lac 48, 52, and 54 Trends (see

Figures 2a and 2b). All samples have been sent to SRC laboratories in Saskatoon, SK for assay analysis.

ANGILAK PROJECT – NUNAVUT

The Angilak Project is situated within the Angikuni Basin, approximately 225 km southwest of Baker Lake

in the Kivalliq Region of Nunavut (Figure 1). The Angilak Project is host to the Lac 50 Uranium Deposit,

which has a historical mineral resource estimate of 43.3M lbs at an average grade of 0.69% U3O8.1

The 2024 Angilak exploration program consist ed of diamond drilling, airborne geophysical surveys, and

surficial sampling and mapping programs. Exploration activities prioritized areas proximal to known zones

of uranium mineralization for expansion and discovery. In addition to the Lac 50 Trend, the Company also

expanded mineralization along the newly term ed Lac 48, Lac 52, and Lac 54 Trends. Samples from the

2024 exploration program have been sent to SRC laboratories and results are currently pending.

Troy Boisjoli, CEO added: “We are extremely excited about the results from our work at the Angilak

Project. The successful identification of uranium mineralization along strike at the deposit, combined with

the confirmation of uranium mineralization across multiple proximal parallel trends, underscores the

immense potential of this project. Thes e results not only extend the footprint of known mineralization

but also illuminate new opportunities for significant resource growth. We believe this progress mark s a

pivotal moment for ATHA as we execute an aggressive growth strategy at a time when the uranium

industry is facing a potential unprecedented structural supply deficit. T his project continues to show

potential to unlock the uranium endowment in Nunavut which could become one of the most significant

emerging uranium districts in recent history.”

Cliff Revering, VP Exploration added: “The objectives we had set for ATHA’s 2024 drilling at Angilak were

to expand the footprint of mineralization of the historic Lac 50 mineralized domains, as well as to identify

new zones of mineralization within the main Lac 50 Trend and proximal exploration target areas, and we

are very happy to report that we were successful in achieving both primary objectives. The combined

results from our drilling campaign and surficial mapp ing program have allowed us to build on the

understanding of the lithological and structural controls on mineralization within this highly prospective

uranium district. The geological picture at Angilak continues to develop and we are excited by the

direction the project is heading. We would also like to extend our appreciation to our technical teams and

contractors for their hard work, dedication , and professionalism in executing this program on time and

within budget.”

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 insuffi cient

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 deri ved 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 o f

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 r esults

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 d ated

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, wou ld 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 cond uct 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 constr ain

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.
