Cosa Resources Exercises Option to Acquire a 100%

Interest in the Heron Copper Project

Vancouver, British Columbia, May 1 3th, 2022 – Cosa Resources Corp. (CSE: COSA) (“ Cosa Resources” or the

“Company”) is pleased to announce that it has , on an accelerated basis, exercised its option (the “Heron Option”)

to acquire a 100% interest in the Heron Copper Project (the “Heron Project”) from the current land holders (the

“Heron Vendors”).

Keith Bodnarchuk, President & CEO, commented: “Having now met the terms of the Heron Option Agreement, we

are excited to officially take 100% ownership of the project. Since completing the IPO in March, Cosa Resources has

remained very active in creating value for stakeholders. Securing 100% ownership of Heron is another value accretive

step. The Company is in a s olid financial position with $2.4 million in the treas ury to continue exploration in the

mining-friendly jurisdiction of Saskatchewan.”

Pursuant to the terms of the Heron Option agreement, Cosa Resources has issued an additional 1,000,000 common

shares of the Company (the “Option Shares”) to the Heron Vendors and satisfied its obligation to incur a minimum

of $100,000 in eligible exploration expenditures on the Heron Project . The Heron V endors will retain a 2% Net

Smelter Return Royalty (the “NSR”) on the Heron Project. Cosa Resources will have the right to repurchase one-half

of the NSR for $2 million in cash, and the remaining one-half of the NSR for $5 million in cash.

In addition to any resale restrictions imposed by applicable securities law, the Option Shares are subject to a 24 -

month hold period with 25% being released every three months commencing on August 1 3, 2023.

About the Heron Project

The Heron Project 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 kilometres

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

copper mineralization at the Janice Lake property.

In April 2022, Cosa Resources completed magnetic and electromagnetic ground geophysical surveys at Heron . The

surveys were designed to follow up on the highest priority target area from the 2021 airborne geophysical survey

and the primary objective was to map and char acterize the electrical and magnetic properties of the subsurface

within the project area to focus future exploration for 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.

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.

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

to project financing and equity issuances; risks and unknowns inherent in all mining projects; contests over title to

properties, particularly title to undeveloped properties; laws and regulations governing the environment, health and

safety; the ability of the communities in which the Company operates to manage and cope with the implications of

COVID-19; the economic and financial implications of COVID-19 to the Company; operating or technical difficulties in
