Cosa Resources Completes Geophysical Surveys at Heron

Copper Project

Vancouver, British Columbia, April 28th, 2022 – Cosa Resources Corp. (CSE: COSA) ( “Cosa Resources” or the

“Company”) is pleased to announce the completion of the field portion of the ground geophysical program at its

flagship Heron Copper Project (“Heron” or the “Project”) in Northern Saskatchewan. Cosa Resources holds an option

to acquire a 100% interest in the Heron Copper Project.

Keith Bodnarchuk, President & CEO, commented: “Following a successful Initial Public Offering and listing on the

Canadian Securities Exchange in March, and having now closed a $2 million non-brokered private placement in April,

our focus has shifted to the exploration of our Heron Copper Project in Northern Saskatchewan. Through the great

work of our technical team, we have completed phase one at Heron, which consisted of ground geophysical survey s

designed to follow-up and advance the most prospective targets generated by our 2021 airborne geophysical survey.

Our technical team is currently reviewing the preliminary data to help guide future exploration at Heron.”

The Survey

The 2022 winter exploration program at Heron consisted of magnetic and electromagnetic ground geophysical

surveys. The surveys were completed in April 2022 and were designed to follow up on the highest priority target

area from the 2021 airborne geophysical survey. The primary objective of the geophysical program was to map and

characterize the electrical and magnetic properties of the subsurface within the project area to focus future drilling

programs for the exploration of sedimentary-hosted copper deposits. The program consisted of a combined total of

60 km of magnetic and electromagnetic survey coverage with a line spacing of 100 m , tightening to 50 m spacing

overtop of the strongest airborne anomalies.

About Heron

Heron is a copper exploration project located in Northern Saskatchewan, approximately 180 kilometres north of La

Ronge. The Project is comprised of three mineral claims totaling 11,122 hectares and is immediately adjacent to the

Janice Lake Copper Property, a highly prospective sedimentary -hosted copper project owned by Forum Energy

Metals Corp. and currently under option to Rio Tinto Exploration Canada. All claims at Heron are within 30 kilometres

of the newly constructed Janice Lake trail , and a high -voltage powerline runs within 4 k ilometres of the central

mineral claim. Heron covers an underexplored area underlain by Wollaston Group sandstones which host the

stratabound sedimentary copper on the parallel Janice Lake property. In August 2021, Cosa Resources completed a

property-wide airborne magnetics survey. The survey successfully outlined multiple target areas based on magnetic

highs interpreted to be similar to the magnetic highs that host c opper mineralization at the Janice Lake property.

Cosa Resources holds an option to acquire a 100% interest in the Heron Copper Project.

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

information.

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 exploratio n and development;

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

manner.

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

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.

Many factors, both known and unknown, could cause actual results, performance, or achievements to be materially

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

on or related to many of these factors. Such factors 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 o r at

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