12.00% CONVERTIBLE UNSECURED DEBENTURE

Due October 19, 2029

DENARIUS METALS CORP. (the "Corporation") for value received hereby acknowledges itself indebted and, subject to the provisions of the Trust Indenture (the "Indenture") dated as of October 19, 2023 between the Corporation and TSX Trust Company (the "Indenture Trustee"), as amended and supplemented as of October 31, 2023, as amended and supplemented as of December 31, 2024 promises to pay to [●], the registered holder thereof, on October 19, 2029 (the "Maturity Date") or on such earlier date as the principal amount thereof may become due in accordance with the provisions of the Indenture the principal sum of $[●] in lawful money of Canada on presentation and surrender of this Debenture at the main branch of the Indenture Trustee in Toronto, Ontario in accordance with the terms of the Indenture and to pay interest on the principal amount thereof from October 19, 2023 at the rate of 12.00% per annum, in like money, in arrears in equal monthly installments (less any tax required by law to be deducted) on the last day of each month and on the Maturity Date (the "Interest Payment Date") and, should the Corporation at any time make default in the payment of any principal or interest, to pay interest on the amount in default at the same rate, in like money.

Interest hereon shall be payable by electronic funds transfer or by cheque mailed to the registered holder thereof and, subject to the provisions of the Indenture, the electronic funds transfer or mailing of such cheque shall, to the extent of the sum represented thereby (plus the amount of any tax withheld), satisfy and discharge all liability for interest on this Debenture.

A Gold Premium Payment (as defined in the Indenture) shall be payable to the holder in accordance with the terms and provisions of the Indenture.

This Debenture is one of the 12.00% convertible unsecured debentures due on the Maturity Date of the Corporation issued or issuable under the provisions of the Indenture (referred to herein as the "Debentures"). The Debentures are limited to an aggregate principal amount of $25,000,000 in lawful money of Canada. Reference is hereby expressly made to the Indenture for a description of the terms and conditions upon which the Debentures are or are to be issued and held and the rights and remedies of the holders of the Debentures and of the Corporation and of the Indenture Trustee, all to the same effect as if

the provisions of the Indenture were herein set forth, to all of which provisions the holder of this Debenture by acceptance hereof assents.

The Debentures will be issued in denominations of $1.00 and integral multiples in excess thereof. This Debenture is convertible, at the option of the holder thereof, upon surrender of this Debenture at the principal office of the Indenture Trustee in Toronto, Ontario, at any time prior to 5:00 pm (Toronto time) on the Business Day immediately preceding the Maturity Date, into common shares in the capital of the Corporation (“Common Shares”) (without adjustment for dividends or distributions on Common Shares issuable upon conversion or for interest accrued on Debentures surrendered for conversion) at a conversion price of $0.45 per Common Share (the “Conversion Price”), all subject to the terms and conditions and in the manner set forth in the Indenture. The holder of a Debenture so surrendered for conversion shall be entitled to receive in cash accrued and unpaid interest in respect thereof for the period from and including the last Interest Payment Date up to but excluding the Date of Conversion. The Indenture makes provision for the adjustment of the Conversion Price in the events therein specified. No fractional Common Shares will be issued on any conversion or payment in lieu thereof. Debentureholders converting their Debentures will receive accrued and unpaid interest thereon.

Upon the occurrence of a Change of Control of the Corporation, the Debentureholders shall have the right, in their sole discretion, to require the Corporation to either: (i) purchase the Debentures, in whole or in part, at a price equal to 101% of the principal amount of such Debentures plus accrued and unpaid interest (if any) up to, but excluding, the date the Debentures are so repurchased; or (ii) if the Change of Control results in a new issuer, convert the Debenture into a replacement debenture of the new issuer in the aggregate principal amount of 101% of the aggregate principal amount of the Debenture; or (iii) convert the Debentures at the Conversion Price.

The indebtedness evidenced by this Debenture, and by all other Debentures now or hereafter certified and delivered under the Indenture, is an unsecured obligation of the Corporation, and is subordinated in right of payment, to the extent and in the manner provided in the Indenture, to the prior payment of all Senior Indebtedness, whether outstanding at the date of the Indenture or thereafter created, incurred, assumed or guaranteed.

The principal hereof may become or be declared due and payable before the stated Maturity Date in the events, in the manner, with the effect and at the times provided in the Indenture.

The Indenture contains provisions making binding upon all Debentureholders outstanding thereunder resolutions passed at meetings of such holders held in accordance with such provisions and instruments signed by the holders of a specified majority of Debentures outstanding, which resolutions or instruments may have the effect of amending the terms of this Debenture or the Indenture.

The Indenture contains provisions disclaiming any personal liability on the part of holders of Common Shares or the directors or officers of the Corporation in respect of any obligation or claim arising out of the Indenture or this Debenture.

This Debenture may only be transferred, upon compliance with the conditions prescribed in the Indenture, in the register to be kept at the principal offices of the Indenture Trustee in Toronto, Ontario and in such other place or places or by such other registrars (if any) as the Corporation with the approval of the Indenture Trustee may designate. No transfer of this Debenture shall be valid unless made to the register by the registered holder thereof or his, her or its executors or administrators or other legal representatives, or his, hers or its attorney duly appointed by an instrument in form and substance satisfactory to the Indenture Trustee or other registrar, and upon compliance with such reasonable requirements as the Indenture Trustee or other registrar may prescribe and upon surrender of this Debenture for cancellation.

10 -

This Debenture shall not become obligatory for any purpose until it shall have been certified by the Indenture Trustee under the Indenture.

This Debenture is governed by the Indenture. If any provisions of this Debenture are inconsistent with the provisions of the Indenture, the provisions of the Indenture shall take precedence and shall govern. Capitalized words or expressions used in this Debenture shall, unless otherwise defined herein, have the meaning ascribed thereto in the Indenture. This Debenture may be executed by electronic means and acceptable by the holder of such electronic Debenture (including, without limitation by facsimile) shall be deemed to be an original and legally effective between the holder, the Corporation and the Indenture Trustee pursuant to the terms of the Indenture.
