ISO Isoenergy Ltd

ATHA Energy Corp. (CSE: 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 announce results from its large-scale electromagnetic (“EM”) surveys at its 100%-owned North Beacon Project and North Crest Project (together, the “Projects”). The Projects are located in Saskatchewan’s Athabasca Basin, within the Company’s North Rim Exploration District (the “North Rim Exploration District”).

EXPLORATION OUTLOOK

ATHA’s recently announced acquisition of Latitude Uranium (CSE: LUR) (“Latitude”) and 92 Energy (OTCQB: NTELF) (“92E”) is expected to provide the pro-forma company with a newly diversified portfolio of uranium projects across the exploration risk curve on top of a strong balance sheet to sufficiently capitalize its exploration-at-scale strategy. Going forward, ATHA’s exploration approach is designed with the intention of providing maximum exploration exposure by investing at scale in a large number of early-stage projects, while also seeking to deliver advanced exploration upside through the expansion of known uranium deposits and discoveries. Subject to the completion of ATHA’s acquisition transactions with 92E and Latitude, ATHA intends to leverage its forecasted $65 million pro-forma cash position to pursue a fully-funded growth strategy with focus on:

• Deposit and Discovery Expansion: Historical resource deposits at the Angilak Deposit and CMB Discoveries, as well as the GMZ Corridor (host to Gemini Discovery) remain underexplored and is expected to provide significant resource and discovery expansion potential on a regional scale.
• Advanced Exploration: Drill ready targets on a number of advanced projects owned by Latitude and 92E have identified uranium mineralization, with active geophysical surveys informing future exploration program decisions by ATHA.
• Greenfield Exploration: Pro-forma land position of 7.1 million acres across some of the highest-grade uranium districts in the world provide ATHA with a robust pipeline of early-stage projects that are currently undergoing geophysical and geochemical analysis.

GREENFIELD EXPLORATION PROGRAM

The completed surveys at the North Beacon and North Crest Projects are part of the Company’s maiden 2023 greenfield exploration program, which comprises a total of seventeen EM surveys being conducted across ATHA’s current 3.8-million-acre exploration portfolio in the Athabasca Basin. To date, full results have been received and processed from seven of seventeen project areas, resulting in over 377 km of conductive lineaments and the definition of 28 prospective targets that have now been identified across the North Rim, East Rim, and Cable Bay exploration districts. The results from today’s announcement represent three of those prospective targets, coincident with uranium mineralization. Additional EM surveys on the remaining twelve 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. The remaining portion of the first phase of ATHA’s greenfield strategy in the Athabasca Basin will include the full integration of the 2023 geophysics and regional geochemistry scheduled for completion in the first quarter of 2024.

Doug Adams, VP Exploration added: “In 2023, ATHA set out to evaluate an industry-leading land position and with a strategy in place to advance 17 projects and 3.4 million acres, ATHA continues to generate high-priority targets in the world’s leading uranium district. Historic showings in the area have identified anomalous surface geochemistry coincident with the magnetic lows and conductive highs in the ZTEM. These results have elevated North Beacon and North Crest to be high-tier targets for immediate follow-up exploration. A gravity survey has been scheduled in Q1 of 2024 to further evaluate the 122 km of conductive lineaments.”

NORTH RIM EXPLORATION PROGRAM

Historic exploration at the North Rim began in the early to mid 1900’s with production ending at mines located near Uranium City once the Eldorado mining and milling facility closed in the early 1980’s. Uranium in the Beaverlodge Mining District is structurally controlled with mineralization found in vein-filled fractures, breccias, and faults. The North Rim District remains highly prospective and is vastly under explored with modern exploration techniques. Furthermore, mining method innovation, proximity to surface, and the presence of existing infrastructure contribute to the prospectivity of this district.

The North Rim District’s exploration program covers a total of 688,268 acres of 100% ATHA owned claims using a combination of Xcite TDEM, ZTEM, MMT, and QMAGt survey types. The objective of the EM program is to identify prospective conductive units such as graphitic sheers and mapping of lithological contacts, which will then be targeted for further investigation. The graphitic sheers are typically formed in pelitic host rock which are known traps for uranium mineralization in the Athabasca Basin.

The North Beacon Project is comprised of 16 mineral claims, totalling 78,435 hectares, positioned in the structural wedge created by the ENE trending Grease River Shear Zone and the northeast trending Snowbird Tectonic Zone. Historic exploration drilling completed in 1967 on the eastern extent of the North Beacon Project intersected anomalous uranium within boulders in the overburden. Unfortunately, drilling did not progress deep enough – approximately 200 m in the North to approximately 800 m in the south – to intersect the unconformity.

The North Crest Project is comprised of 4 mineral claims, totalling 17,797 Hectares that cut across the Snowbird Tectonic Zone, approximately 18 km south of Nisto Mine. Notably, Cameco’s Centennial Deposit is an off-conductor deposit of 60MM lbs hanging wall from the conductive corridor of the Snowbird Tectonic Zone and is located 172 km south of North Crest Project. In 2008, exploration on the North Crest Project included four diamond drill holes targeting the southeast margin of the Snowbird Tectonic Zone, in an area similar to the Centennial discovery hole. The upper 100-300 meters of drilling intersected anomalous geochemistry and prospective alteration associated with brittle and brecciated structures that is often indicative of proximal uranium mineralization.

The recently completed EM surveys at North Beacon, North Crest, North Terra, North Pinnacle Projects, and North Valour-East along with the currently ongoing surveys at North Valour-West, and North Summit, notably represent the first modern exploration work on the projects in fifteen years.

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. 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 any of the Parties 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 none of ATHA, Latitude or 92E are 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.
   1. Mineral resources which are not mineral reserves do not have demonstrated economic viability.
   2. The estimate of mineral resources may be materially affected by geology, environment, permitting, legal, title, taxation, sociopolitical, marketing or other relevant issues.
   3. 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.
   4. Contained value metals may not add due to rounding.
   5. A 0.2% U3O8 cut-off was used.
   6. 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.
   7. Reported by ValOre Metals Corp. in 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.
   8. As disclosed in the above noted technical report, the historic 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.
   9. 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).
