Hayasa Metals Announces Option Agreement

on Vardenis Copper-Gold Project

Vancouver, British Columbia--(Newsfile Corp. - August 27, 2025) - Hayasa Metals Inc. (TSXV: HAY)

(OTCQB: HAYAF) (FSE: FR2) ("

Hayasa

" or the "

Company

") is pleased to announce that it has entered

into an amended and restated option and joint venture agreement (the "

Agreement

") which grants Teck

Resources Limited ("

Teck

") the sole and exclusive option to acquire up to an 80% interest in Mendia

Resources LLC ("

Mendia

"), the company that owns the geological exploration license relating to the

Vardenis copper-gold project located in east-central Armenia (the "

Vardenis Project

"). The Agreement

supersedes the option agreement previously entered into by the Company to acquire up to a 100%

interest in Mendia.

Joel Sutherland, CEO of Hayasa, commented,

"Having Teck as an investor is a positive signal for any

junior exploration company.

I speak for all of us at Hayasa when I say that we are exceptionally

pleased Teck has elected to partner with us on advancing Vardenis.

The introduction of Teck at the

project level continues the momentum we are seeing in the region, and we expect that the next 12

months will be exciting times for HAY shareholders."

Dennis Moore, President and Chairman of Hayasa, added,

"The partnership with Teck highlights the

geological potential of Vardenis and reflects the strategic value of our work to date. We are delighted

to align with a world-class operator that brings both technical expertise and financial capacity. This

agreement lays a clear path forward for the project while preserving long-term upside for our

shareholders."

Highlights of the Agreement

The Agreement provides for the following:

The Company and the existing majority shareholder of Mendia (the "

Existing Shareholder

") will

grant Teck the sole and exclusive option to acquire a 70% interest in Mendia (the "

Initial Option

"),

which may be exercised by Teck upon (i) incurring an aggregate of US$15 million in exploration

expenditures on the Vardenis Project by December 31, 2029, (ii) fulfilling its firm commitment to

complete 4,300 meters of diamond drilling on the Vardenis Project by October 31, 2026, including

3,000 meters by December 31, 2025, and (iii) making

any required payments to the Existing

Shareholder.

If Teck exercises the Initial Option, it will have a further sole and exclusive option to acquire an

additional 10% interest in Mendia, which would bring Teck's total interest in Mendia to 80% (the

"

Second Option

"). Teck may exercise the Second Option by delivering to Hayasa and the

Existing Shareholder a National Instrument 43-101 compliant pre-feasibility study in respect of the

Vardenis Project within six years of exercising the Initial Option. Teck will receive the remaining

10% interest in Mendia held by the Existing Shareholder for a US$3.5 million payment. Following

Teck's exercise of the Second Option, the shareholders of Mendia are expected to be as follows:

Teck (80%) and Hayasa (20%).

During the term of the Initial Option and, if applicable, the Second Option, Teck will be solely

responsible for funding all expenditures and costs relating to the Vardenis Project, including costs

related to keeping the Vardenis Project in good standing.

Hayasa will initially be the manager of the Vardenis Project during the term of the Initial Option, with

Teck having the right to replace Hayasa as the manager at any time.

If Teck incurs a minimum of US$2.5 million in the 30-month period following the date of the

Agreement but chooses not to exercise the Initial Option, the Agreement will terminate and Teck

will be granted a 1.0% net smelter returns royalty on the Vardenis property, payable by Mendia.

If Teck exercises the Initial Option and elects not to pursue the Second Option, or if Teck exercises

the Second Option, a corporate joint venture (the "

Joint Venture

") will be deemed to be formed

between Teck and Hayasa (and if applicable, the Existing Shareholder) (each, a "

Shareholder

")

in accordance with the terms of the Agreement. A Shareholder's interest in Mendia will be

converted to a 1.0% net smelter return if its interest is diluted to below 10% or if it defaults on cash

calls in certain circumstances.

For a period of 18 months from the Joint Venture formation date (the "

Deferral Period

"), Hayasa

may elect to defer the contribution of its proportionate share of the costs of approved programs,

which costs will be contributed by Teck on behalf of Hayasa and will become repayable by Hayasa

within 18 months from the end of the Deferral Period.

The Agreement is subject to certain conditions precedent, including the approval of the TSX Venture

Exchange.

About the Vardenis Project

The Vardenis Project is located in the Central Tethyan Belt in east central Armenia, on a road-

accessible property spanning 9,399 hectares. In 2023, the Company entered into an option agreement

with Mendia and its majority shareholder, which secured the Company's option to earn a 100% interest

in the Vardenis Project (see Hayasa's news release dated June 6, 2023). This option agreement has

been superseded by the Agreement.

The Vardenis project lies 25 km along strike and within the same belt as the 4.8 million ounce Amulsar

gold deposit, where production is planned to commence in early 2026.

A former Dundee Precious

Metals project, previous exploration at Vardenis defined an area of advanced argillic and QSP (quartz-

sericite-pyrite) alteration, 35 km

2

in size, which hosts seven mineralized zones arranged in a concentric

arc.

In late 2023, the Company completed 770 meters of diamond drilling in the Razmik copper-

molybdenum zone which encountered long sulfide-rich intervals displaying strong alteration, brecciation

and quartz veining indicative of porphyry-style mineralization.

Chief Financial Officer Paul Hansed to retire at year end

Hayasa also announces that its Chief Financial Officer,

Paul Hansed

, will be retiring at the end of the

2025 calendar year. Paul's career spans 17 years in the junior mining sector, following a distinguished

tenure of 19 years at KPMG. He will remain actively involved in training and onboarding his successor,

who the Company expects to announce prior to year-end.

Joel Sutherland, CEO, commented:

"Paul is an excellent CFO, his attention to detail is unequalled and

his perspective will be missed.

It is our hope that 2026 brings a lower handicap Paul's way and, in all

seriousness, we wish Paul peace and prosperity as he begins his retirement."

Dennis Moore, President and Chairman, added:

"Paul has been a pillar of strength for this company,

providing trusted financial leadership during a critical period of growth. We are grateful for his

dedication and service, and we wish him every success in his well-earned retirement."
