Cosa Resources Begins Airborne Geophysical Survey at

Charcoal and Castor Uranium Projects

Vancouver, British Columbia, November 15, 2022 – Cosa Resources Corp. (CSE: COSA) (“Cosa Resources” or the

“Company”) is pleased to announce the start of an airborne geophysical survey on the Charcoal and Castor uranium

projects. Both projects are 100% owned by the Company and located in the prolific Athabasca Basin in Northern

Saskatchewan.

Keith Bodnarchuk, President & CEO, commented: “ The start of our exploration program on the recently acquired

Charcoal and Castor uranium projects is an exciting development for Cosa . The timing of the airborne geophysical

survey is important because it will set the C ompany up for more advanced exploration in 2023. We look forward to

advancing our current uranium assets and continuing to explore value accretive opportunities for our team and

project portfolio.”

The Survey

Geotech Airborne Geophysical Surveys (Geotech Ltd.) has been contracted to fly a 1,540 line -km of Versatile Time-

Domain Electromagnetic (VTEM™ Plus) and Horizontal Magnetic Gradiometer survey over the Castor and Charcoal

projects. The VTEM™ Plus system will be flown over the project lands with flight lines spaced at 150m apart,

providing high -resolution imaging of potential mineralizing systems associated with basement -hosted uranium

deposits. The survey is now underway and will help to characterize the geology of the projects by locating conductive

stratigraphy and alteration zones in areas of structural complexity. Surveying is expected to be complete within two

to four weeks and data processing and interpretation of the results will follow immediately afterward.

The Projects

Charcoal

A large, 21,080 ha property, Charcoal is located 52 km northeast of Cameco Corp.’s Rabbit Lake – Eagle Point mine

operations. The property sits within a prominent magnetic low anomaly that extends northeast from the mine

(Figure 1). The magnetic low signature likely indicates the presence of prospective metasedimentary bedrock

beneath the glacial till cover. Additionally, historical assessment records from the Government of Sas katchewan

indicate the presence of numerous airborne electromagnetic conductors, possibly indicating the presence of

graphitic metasediments and associated brittle faults, which are often associated with uranium mineralization in the

Athabasca Basin. The p roperty is 8 km up-ice from a historical radioactive boulder field. As Charcoal is beyond the

basin edge, basement rocks extend to the top of the bedrock and there is no overlying sandstone.

Castor

Castor, like Charcoal, lies beyond the Athabasca Basin edge and therefore has no overlying sandstone cover. The

property is located 55 km north of Cameco Corp.’s Rabbit Lake – Eagle Point uranium mine operations (Figure 1).

Basement rocks extend to the top of the bedrock. Castor is located at t he intersection of a prominent northeast

trending magnetic low anomaly that is roughly parallel to the Eagle Point – Collins Bay magnetic low at Charcoal and

an east-west trending magnetic low anomaly. This intersection may be an area of enhanced structura l complexity

that would be prospective for uranium mineralization.

“may”, “would”, “could”, “schedule” and similar words or expressions, identify forward‐looking statements or

information. These forward looking statements or information relate to, among other things: the exploration,

development, and production at the Company’s mineral projects.

Forward‐looking statements and forward‐looking information relating to any future mineral production, liquidity,

enhanced value and capital markets profile of the Company, future growth potential for the Company and its

business, and future exploration plans are based on management’s reasonable assumptions, estimates, expectations,

analyses and opinions, which are based on management’s experience and perception of trends, current conditions

and expected developments, and other factors that management believes are relevant and reasonable in the

circumstances, but which may prove to be incorrect. Assumptions have been made regarding, among other things,

the price of metals; no escalation in the severity of the COVID ‐19 pandemic; costs of exploration and development;

the estimated costs of development of exploration projects; the Company’s abili ty to operate in a safe and effective

manner.

These statements reflect the Company’s respective current views with respect to future events and are necessarily

based upon a number of other assumptions and estimates that, while considered reasonable by management, are

inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies.

looking statements or forward‐ looking information and the Company has made assumptions and estimates based

on or related to many of these factors. Such fac tors include, without limitation: the Company's dependence on one

mineral project; precious metals price volatility; risks associated with the conduct of the Company's mining activities;

regulatory, consent or permitting delays; risks relating to reliance on the Company's management team and outside

contractors; the Company's inability to obtain insurance to cover all risks, on a commercially reasonable basis or at

all; currency fluctuations; risks regarding the failure to generate sufficient cash flow from operations; risks relating
