Cosa Resources Announces Summer

Exploration Plans for Athabasca Basin

Uranium Projects

Vancouver, British Columbia--(Newsfile Corp. - May 9, 2024) -

Cosa Resources Corp.

(

TSXV: COSA

)

(

OTCQB:

COSAF

) (

FSE: SSKU

) ("

Cosa

" or the "

Company

") is pleased to announce its summer

exploration plans for its portfolio of Athabasca Basin uranium projects.

Highlights

Diamond drilling at Ursa to follow up positive winter drilling results and test second high priority

target area

Ambient Noise Tomography (ANT) surveys to prioritize strike at Ursa and follow-up airborne survey

results at Orion

Airborne Electromagnetic (EM) and Gravity surveying at Aurora and Orbit to advance these

shallow, prospective projects toward drill readiness for 2025

Keith Bodnarchuk, President & CEO, commented:

"After a successful winter drill program, we are eager

to return to the field and continue exploration at the 100% owned Ursa Project. Alongside summer

drilling at Ursa, including following up on the exciting results at drill hole UR-24-03, we will be

advancing multiple other projects to drill readiness for 2025. With the completion of our

oversubscribed C$6.5 million bought deal financing earlier this year, we are fully funded to complete

this work and well positioned to take advantage of a strengthening uranium market by expanding our

pipeline of exciting drill targets across many of our highly underexplored uranium projects."

Andy Carmichael, VP of Exploration, commented:

"We are planning a busy summer season in the

southeastern Athabasca with exploration plans that respond to the encouraging results of initial

drilling at Ursa and reflect the discovery potential we see in our Orion, Aurora, and Orbit projects.

Completing ANT before resuming drilling at Ursa will improve prioritization of existing targets and

potentially highlight new target areas on trend. ANT work at Orion will follow-up the prominent,

kilometre-scale sandstone hosted conductivity anomaly identified in 2023 and guide future

exploration efforts. Work at Aurora and Orbit will advance these prospective projects towards drill

readiness, which, despite being within 25 kilometres of the Key Lake Mill, have seen little to no

modern exploration."

Ursa and Orion Ambient Noise Tomography Surveys

Ambient Noise Tomography (ANT) surveying is planned at Ursa and Orion beginning in May (Figures 1

to 3). Cosa expects ANT to prove a rapid, low-cost, low-impact method to evaluate broad areas for

prospective structures and alteration zones. Using data collected from a grid of compact, standalone

sensors to measure naturally occurring seismic activity, ANT produces a three-dimensional model of

subsurface seismic wave velocity. As the Athabasca sandstone is relatively homogenous and seismic

wave velocity varies with changes in the host rock, velocity variations can be attributed to post-

Athabasca faulting and/or alteration zones characteristic of the region's high-grade uranium deposits.

Although ANT is relatively new to the Athabasca Basin, recent exploration drilling in the region targeting

ANT anomalies has successfully intersected zones of hydrothermal alteration at depth.

At Ursa, ANT will be deployed over the 27-kilometres of conductive strike length hosting the alteration

and structure intersected by UR24-03 at Kodiak, the Kodiak North, Smokey, and Panda West target

areas, and all three weakly mineralized historical drill holes within the Project (Figure 2). Cosa

anticipates preliminary ANT results will influence Ursa summer drilling planned to begin in August.

At Orion, ANT will follow up a prominent zone of anomalous sandstone conductivity identified by Cosa's

2023 MobileMT™ survey. The 4-kilometre-long, 1.4-kilometre-wide anomaly is coincident with flexures in

basement conductive trends (Figure 3). Cosa will use ANT to locate seismic velocity anomalies

coincident with the conductivity features and to optimize the locations of ground EM surveying used to

generate targets for diamond drilling.

Aurora and Orbit Airborne Surveys

Cosa will complete comprehensive airborne electromagnetic (EM) and gravity surveys to advance its

Aurora and Orbit properties toward drill readiness for 2025 (Figure 4). EM surveying will be completed

by Geotech Ltd.'s helicopter borne VTEM™ Plus system with the objective of identifying basement-

hosted conductivity anomalies consistent with prospective graphitic structures and/or large zones of

hydrothermal alteration. Gravity surveying will be completed by Xcalibur Multiphysics's Falcon® Airborne

Gravity Gradiometer system (AGG) with the objective of identifying gravity anomalies consistent with

large zones of hydrothermal alteration and to improve the understanding of basement geology. Top

priority drill targets would be gravity low anomalies coincident with basement-hosted conductive

features. Airborne surveys commenced in early May.

Ursa Diamond Drilling

Planning is ongoing for summer diamond drilling at Ursa. Drilling is expected to include following-up the

broad zone of hydrothermal alteration and post Athabasca structure intersected well above the

unconformity by drill hole UR24-03 (Figure 5; see Cosa news release dated April 24, 2024) as well as

initial drill testing of a second target area. It is anticipated that ANT survey results will be used to

influence drill strategy and targeting.

About Cosa Resources Corp.

Cosa Resources is a Canadian uranium exploration company operating in northern Saskatchewan. The

portfolio comprises roughly 209,000 ha across multiple projects in the Athabasca Basin region, all of

which are underexplored, and the majority reside within or adjacent to established uranium corridors.

Cosa's award-winning management team has a long track record of success in Saskatchewan. In 2022,

members of the Cosa team were awarded the AME Colin Spence Award for their previous involvement

in discovering IsoEnergy's Hurricane deposit. Prior to Hurricane, Cosa personnel led teams or had

integral roles in the discovery of Denison Mines' Gryphon deposit and 92 Energy's Gemini Zone and

held key roles in the founding of both NexGen and IsoEnergy.

Cosa's primary focus through 2024 is initial drilling at our Ursa Project, which captures over 60-

kilometres of strike length of the Cable Bay Shear Zone, a regional structural corridor with known

mineralization and limited historical drilling. It potentially represents the last remaining eastern

Athabasca corridor to not yet yield a major discovery. Modern geophysics completed by Cosa in 2023

identified multiple high-priority target areas characterized by conductive basement stratigraphy beneath

or adjacent to broad zones of inferred sandstone alteration – a setting that is typical of most eastern

Athabasca uranium deposits. Initial drilling results from Ursa in winter 2024 are positive and include the

intersection of a broad zone of alteration with associated structure in the Athabasca sandstone located

250 to 460 metres above the sub-Athabasca unconformity. Follow-up is planned in the second half of

2024.
