Moon River Moly Ltd. Provides Early Warning

Disclosure

Toronto, Ontario--(Newsfile Corp. - May 8, 2026) - Moon River Moly Ltd. (TSXV: MOO) (OTCQB:

MRIVF) ("

Moon River

" or the "

Company

") - announces that an early warning report has been filed in

respect of Mr. Ian McDonald's ("

McDonald

") holdings of the Company.

On November 15, 2023, McDonald was granted 600,000 stock options ("

Options

") to purchase

common shares of the Company ("

Common Shares

"), 200,000 of which vested immediately and an

additional 200,000 vested on each of the first and second anniversaries of the grant date.

Immediately prior to the Option Vesting (as defined below), McDonald had beneficial ownership of, or

control or direction, over 2,944,000 Common Shares and 200,000 Options which had vested or will vest

within 60 days of such date, pursuant to previously issued Options by the Company, representing

approximately 8.93% of the issued and outstanding Common Shares on a non-diluted basis

(approximately 9.42% of the issued and outstanding Common Shares on a partially diluted basis).

On September 16, 2024, 200,000 of the Options had already vested and another 200,000 would vest

within 60 days of such date. Accordingly, as of such date, McDonald had beneficial ownership of (within

the meaning of National Instrument 62-104 -

Take-Over Bids and Issuer Bids

), or control or direction

over, 2,944,000 Common Shares and 400,000 Options (the "

Option Vesting

"). After giving effect to the

Option Vesting, McDonald had beneficial ownership of, or control or direction over, approximately 8.9%

of the then issued and outstanding Common Shares on a non-diluted basis (approximately 10.02% of

the then issued and outstanding Common Shares on a partially diluted basis).

On September 15, 2025, the Company issued 336,280 Common Shares from treasury (the

"

Issuance

"). Following the Issuance, the resulting beneficial ownership of McDonald in respect of the

Common Shares and securities convertible into Common Shares, fell below 10% of the issued and

outstanding Common Shares on a partially diluted basis, as McDonald had beneficial ownership of, or

control or direction over, approximately 8.78% of the then issued and outstanding Common Shares on a

non-diluted basis (approximately 9.92% of the then issued and outstanding Common Shares on a

partially diluted basis) (the "

Dilution

"). The Dilution arose solely as a result of the Issuance without any

action being taken by McDonald.

Subsequently, on September 16, 2025, due to the impending vesting within 60 days of an additional

200,000 previously granted Options, McDonald had beneficial ownership of, or control or direction over,

2,944,000 Common Shares and 600,000 Options (the "

Second Option Vesting

"). After giving effect to

the Second Option Vesting, McDonald had beneficial ownership of, or control or direction over

approximately 8.78% of the then issued and outstanding Common Shares on a non-diluted basis

(approximately 10.46% of the then issued and outstanding Common Shares on a partially diluted basis).

More recently, on February 26, 2026, McDonald acquired 776,470 units of the Company ("

Units

") at a

price of $0.85 per Unit, pursuant to a private placement offering (the "

Acquisition

", and collectively with

Option Vesting and Second Option Vesting, the "

Acquisitions

"). Each Unit consisted of one Common

Share and one half of one Common Share purchase warrant ("

Warrant

"). Each Warrant is exercisable

to acquire one Common Share at a price of $1.15 per Common Share for a period of 24 months,

provided that the Warrants could not be exercised until April 27, 2026.

After giving effect to the Acquisitions and the Issuance, as of February 27, 2026, McDonald had

beneficial ownership of, or control or direction over, 3,720,470 Common Shares, 600,000 Options

exercisable within 60 days and 388,235 Warrants, representing approximately 9.9% of the issued and

outstanding Common Shares on a non-diluted basis (approximately 12.22% of the issued and

outstanding Common Shares on a partially diluted basis).
