Canstar Options Golden Baie; Will Receive Initial 15.8M

Shares and $208K Cash , with Additional Equity Tranches

to Follow

Toronto, Ontario – March 23, 2026 – Canstar Resources Inc. (TSX-V: ROX; OTCID: CSRNF)

(“Canstar” or the “Company”) is pleased to announce that, further to its press release dated

February 17, 2026, it has executed the definitive option agreement (the “Agreement”) with

Churchill Resources Inc. (“CRI ”). The Agreement is effective as of March 20, 2026, and

grants CRI the right to earn a 100% interest in Canstar’s Golden Baie gold–antimony project

located in Newfoundland (the “Golden Baie Project”).

In connection with the execution of the Agreement, and subject to final approval of the TSX

Venture Exchange (the “TSXV”) – which the Company expects to receive shortly – and other

customary conditions. Canstar will receive the following consideration within three

business days of such approval:

• Cash Payment: A cash payment of approximately $208,167, representing

reimbursement of existing cash bonds posted on the Golden Baie Project.

• Initial Share Issuance: 15,834,097 common shares of CRI, representing

approximately 5.0% of CRI’s issued and outstanding shares on a post -issuance

basis. Based on CRI’s closing share price of $ 0.10 per share on March 20, 2026, the

initial tranche has an indicative market value of approximately $ 1.6 million. These

shares are subject to applicable statutory hold periods.

The Agreement provides for Canstar to receive up to an additional 4.99% ownership in CRI,

delivered in four subsequent tranches of approximately 1.25% each over 6 month intervals

during the 24 -month option period. In accordance with TSXV requirements, each 1.25%

tranche is subject to a maximum issuance of 7,520,000 shares per tranche, and the

aggregate maximum number of CRI shares issuable to Canstar under the Agreement is

45,914,097 shares. The actual value of the initial share consideration, as well as the value

of all future tranches, will be determined by CRI’s market capitalization at the time of each

respective issuance, as each tranche is calculated as a percentage of CRI’s then-

outstanding shares. This structure provides Canstar wi th direct economic leverage to the

advancement of the Golden Baie Project.

Summary of Additional Key Terms

Royalty: Canstar retains a 0.5% net smelter return (“NSR”) royalty on any future mineral

production from the Golden Baie Project upon CRI’s exercise of the option. The royalty does

not include a buyback provision. The Golden Baie Project remains subject to an existing

2.0% NSR royalty.

Work Commitments: To earn a 100% interest in the Golden Baie Project, CRI must incur a

minimum of $1,000,000 in exploration expenditures within the first 12 months of the option

and a minimum of $5,000,000 in total exploration expenditures within 24 months.

Eliminated Holding Obligations: As a result of the Agreement, Canstar is no longer

responsible for approximately $600,000 in assessment expenditures that were required by

August 2026 to maintain the Golden Baie Project in good standing.

Reversion: If CRI does not satisfy the required minimum exploration expenditures within the

specified timeframes, the option will terminate and the Golden Baie Project will revert to

Canstar, subject to the terms of the Agreement.

Juan Carlos Giron Jr., Canstar’s President & CEO, commented:

“With the definitive agreement executed, this transaction is effectively closed, subject to

final TSXV approval.

The equity structure is a key advantage. Each tranche is issued as a fixed percentage of

Churchill’s outstanding shares, meaning the value to Canstar scales directly with

Churchill’s market capitalization as the Golden Baie Project advances. This preserves long-

term upside while immediately strengthening our balance sheet and focus.

This transaction allows us to retain meaningful exposure to a project we know well, while

redeploying capital and attention toward our core VMS portfolio , led by our flagship Mary

March volcanogenic massive sulphide (“VMS”) project.

Golden Baie has strong fundamentals and a clear path to advancement under Churchill’s

stewardship. As exploration results emerge and the market gains familiarity with the asset,

we see a credible pathway for value creation.

More broadly, we are nearing the end of a highly productive first quarter for Canstar. In

addition to the Golden Baie option, since the start of the year, we have finalized a joint

venture of up to $11.5 million with VMS Mining Corporation , received an additional $1M in

non-dilutive exploration capital , advanced multiple geophysical programs , secured a drill

permit for the 2026 Mary March Campaign, expanded and consolidated our Mary March land

position and announced a letter of intent to acquire a new project in Sweden in one of the

world’s most well-endowed VMS mining jurisdictions.

As we move through 2026, we are transitioning from foundation-building to catalyst delivery.

With a stronger financial position, a sharper focus on VMS exploration, and a clear pipeline

of exploration milestones, we believe the Company is well positioned for a compelling year

ahead, and that the most important value drivers are still in front of us.”

Acknowledgement

Canstar acknowledges the financial support of the Junior Exploration Assistance (“JEA”)

Program from the Government of Newfoundland and Labrador Department of Industry,

Energy and Technology, which has been a valuable contribution to the exploration programs

on the Company’s Buchans-Mary March and the Golden Baie Project.

About Canstar Resources Inc.

Canstar Resources Inc. (TSXV: ROX) is a mineral exploration company focused on the

discovery of high -grade polymetallic deposits through technically rigorous exploration in

proven mineral districts.

The Company’s flagship asset is the Mary March Project, a large land package located

approximately 20 km east of the historic Buchans Mining Camp in central Newfoundland,

which produced some of the highest -grade volcanogenic massive sulphide (“VMS”)

deposits globally. Mary March hosts high-grade copper, zinc, gold and silver mineralization,

volcanic rocks consistent with the stratigraphy that hosts the Buchans deposits, and large

hydrothermal alteration zones indicative of a significant mineralizing system. Despite its

proximity to the Buchans camp, the property has seen limited modern exploration since the

original discovery, leaving substantial portions of the system underexplored.

Canstar’s exploration programs are supported by a technical team with extensive

experience exploring for and advancing volcanogenic massive sulphide deposits globally.

The Company’s exploration strategy combines district -scale geological targeting with

disciplined exploration programs designed to identify new discoveries. In addition to Mary

March, Canstar maintains exposure to additional discovery opportunities through projects

including the Golden Baie Project in Newfoundland, which hosts high- grade gold and

antimony mineralization along a major mineralized structural corridor.
