ATHA Energy Announces Results from Large-Scale Electromagnetic Survey Program ON Plateau Project

Exploration Programs

ATHA ENERGY ANNOUNCES RESULTS FROM LARGE-SCALE ELECTROMAGNETIC SURVEY PROGRAM ON

PLATEAU PROJECT

Vancouver, British Columbia , October 31, 2023 – ATHA Energy Corp. (CSE: SASK) (FRA: X5U) (OTCQB:

SASKF) (“ATHA” or the “ Company”), holder of the largest uranium exploration portfolio in the highest

grade uranium district in the world, is pleased to announce results from its large -scale electromagnetic

(“EM”) surveys at its 100% -owned Plateau project (the “ Project”), located in Saskatchewan’s Athabasca

Basin, within the Company’s Cable Bay exploration district (the “Cable Bay Exploration District”).

The completed survey is part of the Company’s maiden 2023 exploration program, which comprises a

total of seventeen EM surveys being conducted across the Athabasca Basin on ATHA’s 3.4 -million-acre

exploration portfolio. The 2023 exploration program is organized into four distinct exploration districts:

North Rim District, East Rim District, West Rim Distri ct, and Cable Bay District – encompassing all major

producing, past producing, and developing uranium mining camps within the Athabasca Basin. In August

of this year, the Company commenced the largest ever multi -platform EM survey in the history of the

Athabasca Basin, designed to de-risk and test ATHA’s dominant land package, which is the largest reported

land package in the history of the Athabasca Basin and further complimented by ATHA’s 10% carried

interests on claims held by NexGen Energy Ltd. (TSX: NXE) and IsoEnergy Ltd. (TSX‐V: ISO).

To date, results have been received and processed from four of seventeen project areas, resulting in 122

km of conductive lineaments and the identification of fifteen prospective targets across the North Rim,

East Rim, and Cable Bay exploration districts . Additional EM surveys on the remaining thirteen projects

have also been completed and are now being processed, with the anticipation of those results further

defining the prospectivity of the largest exploration portfolio in the Athabasca basin throughou t the

remainder of 2023. The remaining portion of the first phase of ATHA’s exploration -at-scale strategy will

include the full integration of the 2023 geophysics and regional geochemistry scheduled for completion

in the first quarter of 2024.

HIGHLIGHTS

● Expert’s MMT survey (the “ Survey”) was successfully deployed at Plateau, with a total of 2,068-

line km flown;

● The Plateau Project has 25 km of exposure along the Cable Bay Shear Zone (the “CBSZ”), which is

a major crustal-scale structure that extends across the Athabasca Basin in a Southwest-Northeast

strike direction;

● The CBSZ shows similar geological characteristics to the Wollaston -Mudjactic Transition Zone ,

which is a corridor located 65 km to the west of the Project and hosts the Cigar Lake and McArthur

River mines that respectively represent the highest-grade and largest high-grade uranium mines

in the world;

● The CBSZ structural corridor has known uranium occurrences and is comprised of the prospective

Mudjatik Domain, which contains pelitic, graphitic-pelitic, and mylonite units that are all known

hosts for uranium mineralization;

● The Survey indicates the Plateau Project area hosts the right geological conditions to host both

unconformity and crystalline basement styles of uraniu m and similar to those found at the Cigar

Lake and Eagle Point mines, respectively; and

● Analysis of the Survey showed approximately 62 km of cumulative conductors found across the

Project area, including two highly prospective targets coincident with conductors and prospective

structural disruptions that are on trend and potential source from previously discovered

radioactive boulders.

Doug Adams, VP Exploration added: “The completion of the Cable Bay Plateau MMT survey by Expert has

defined the lineation of the Cable Bay Shear Zone through the median and northern portion of the

property. Coincident with this regional structure are occurrences of enhanced conductivity, which will be

the basis for a targeted evaluation of the trend, including the 2D and 3D inversions scheduled for the end

of 2023 , followed by the integration of the 3D geochemistry and geology. The full integration of all

geophysical, geochemistry and geological data sets will be completed in the first quarter of 2024 and will

be part of the Cable Bay Exploration Districts regional evaluation.”

CABLE BAY EXPLORATION PROGRAM

The Cable Bay Exploration District derives its name from the Cable B ay Shear Zone , a crustal -scale

structure that extends North to South across the Athabasca Basin. During previous uranium cycles, most

exploration focused on the southern and northern margins of the Athabasca Basin where uranium

mineralization was discovered, with only limited exploration activity completed along the CBSZ – making

it one of the last remaining untested crustal -scale structures in the Athabasca Basin . With the

development of new technologies and a better understanding of controls on uranium mineralization, the

Cable Bay Exploration District has seen renewed interest, with a significant increase in exploration along

the corridor. The CBSZ is highly prospective for the discovery of both unconformity and basement styles

of uranium mineralization.

ATHA’s 2023 survey program in the Cable Bay Exploration District provides the Company with EM

coverage over a total of 402,219 acres of 100% owned claims, using a combination of Xcite TDEM and

MMT surveys depending on the geological settings.

The Plateau Project is comprised of nine mineral claims, totalling 67,307 acres along the Cable Bay fault

corridor. The Cable Bay fault is a brittle structural zone at the Mudjatik and Taltson suture zone, with

radioactive boulders discovered in 1981 on an island in Cree Lake that measured 2 ,000 cps. Those

showings, along with results from the Survey, demonstrate the high prospectivity of the Plateau Project

and the Cable Bay Exploration District as a whole.
