Cosa Resources Acquires Helios Uranium Property in Athabasca

Basin, Saskatchewan

Vancouver, British Colum bia, April 6, 202 3 – Cosa Resources Corp. (CSE: COSA) ( “Cosa Resources” or the

“Company”) is pleased to announce it has acquired the Helios property covering 12,835 hectares of prospective

uranium exploration ground in the northern Athabasca Basin. The property was acquired by staking and is 100%

owned by Cosa Resources with no encumbrances.

Highlights

 Target areas include the southern extension of a conductive trend with weak uranium mineralization and

over 15 kilometres of strike length along a major structural zone.

 Cosa’s 100% owned uranium exploration portfolio now comprise s 100,652 hectares of highly prospective

exploration ground in the Athabasca Basin.

 Low-cost staking has expanded Cosa’s s trategically located portfolio to five properties within prospective

uranium corridors.

Keith Bodnarchuk, President & CEO, commented: “ Similar to our Ursa project, this is an example of our technical

team leveraging past experience and discovery success to identify overlooked , cost-effective acquisitions. The

acquisition cost for Helios was only ~$8,000. With a land package now totaling more than 100,000 hectares, we

continue to create a strong pipeline of projects in the prolific Athabasca Basin.”

Andy Carmichael, VP of Exploration commented: “Despite containing electromagnetic conductors, a major structural

zone, and being located along strike of uranium occurrences, t he Helios area has been largely overlooked since the

early 1980s. As only two historical drill holes have been completed within the property, exploration potential is

excellent and we look forward to advancing this early-stage asset.”

The Helios Property

The 12,835-hectare Helios property was acquired by staking and is 100% owned by Cosa Resources with no

encumbrances. The property is located 14 kilometres south of the northern rim of the Athabasca Basin and 2 8

kilometres southwest of the community of Fond du L ac. Provincial winter roads extending from Stony Rapids to

Fond du Lac and Uranium City provide ground access to the area (Figure 1).

The broader Helios area was initially explored from 1968 to 1970 and again from 1977 to 1981. Work in the latter

period discovered the Ware’s Uran ium Occurrence , a zone of outcropping sandstone cut by uranium -bearing

fracturing located six kilometres along strike to the north of Helios . Limited f ollow-up drilling in 1979 determined

the fracturing penetrates the full thickness of the Athabasca sands tone and drill hole 3991H-03 intersected 0.18%

U3O8 over 0.1 metres within a zone of hydrothermal alteration at the unconformity. Little additional follow-up was

completed and minimal modern exploration has been completed throughout the area.

Two initial target areas have been identified on the property. The northern portion of Helios covers the extension

of two sub -parallel, curvilinear conductive trends flanking a central magnetic high. Results from a 2005 airborne

electromagnetic survey suggest these conductive trends continue onto the Helios property . The Ware’s Uranium

Occurrence is associated with the more westerly of these trends (Figure 2). A 2007 drill hole testing this trend four

kilometres north of Helios intersected favourable illitic and chloritic clay patterns over broad intervals in the middle

to lower sandstone . The depth to the unconformity is expected to be between 375 and 500 metres within the

northern target area.

The southern portion of Helios covers 15 kilometers of the Grease River Shear Zone (GRSZ), a major east-northeast-

trending basement structure with a mapped length of over 300 kilometres (Figure 2). The Fond du Lac uranium

deposit, located 29 kilometres northeast of Helios, is interpreted to be related to the GRSZ. Dr illing immediately

east of Helios suggests that post- Athabasca faulting related to the shear zone has offset the sub -Athabasca

unconformity by up to 30 metres . Within the property, historical electromagnetic and DC- resistivity surveys have

defined approximately five kilometres of basement -hosted electromagnetic conductors associated with the GRSZ

with potential for a further 10 kilometre extension to the west-southwest (Figure 2). The depth to the unconformity

is interpreted to be between 445 and 850 metres in the southern target area.

With only two drill holes completed on the property, mineralization along strike to the north, and the presence of a

major structural feature, t he early-stage Helios property warrants considerable work . Initial steps will include

reinterpretation of historical airborne surveys in advance of ground work to develop targets for drill testing. Cosa is

pleased to add the Helios property to its portfolio and will continue to search for and acquire highly prospective

projects that have been overlooked and underexplored.
