NON-BROKERED PRIVATE PLACEMENT OF UNITS

The Offering shall consist of up to 200,000,000 units of the Company (the "Units") at a price of C$0.055 per Unit (the “Issue

Price”) on a pre-Consolidation basis, or 40,000,000 Units at a price of $0.275 per Unit on a post -Consolidation basis, for

gross proceeds of up to C$11,000,000. Each Unit comprises one common share (a “Share”) and one-half of one common

share purchase warrant ( each whole warrant, a “ Warrant”). Each Warrant entitles the holder to purchase one additional

Share of the Company at an exercise price of C$0.08 (pre-Consolidation) or $0.40 (post-Consolidation) for a period of thirty

six (36) months from closing of the Offering.

It is anticipated that certain directors and officers of the Company will participate in the Offering. In addition, Nexa

Resources S.A. (“Nexa”) and Compañia de Minas Buenaventura SAA (“Buenaventura”) may participate in the Offering to

maintain their respective pro-rata interests in the Company. It is not known at this time if pre -emptive rights held by Nexa

and Buenaventura will be exercised. In the event these pre-emptive rights are exercised, the Company may issue up to an

additional 132 million Shares (pre -Consolidation) in the Offering at the Issue Price for additional gross proceeds to the

Company of approximately C$7.26 million.

All securities to be issued pursuant to the Offering will be subject to a four -month hold period under applicable securities

laws in Canada. Finder’s fees may be payable on a portion of the Offering. The Offering is subject to certain conditions

customary for transactions of this nature, including, but not limited to, the receipt of all necessary approvals, including the

approval of the TSX Venture Exchange (the “Exchange”).

The Company plans to use the net proceeds to fund an initial drill program at the Silvia gold-copper project, resource

expansion at Ayawilca including targeting of high-grade zinc mineralization, and for corporate and general working capital

purposes.

The participation of any insiders in the Offering may be considered a related party transaction within the meaning of

Multilateral Instrument 61-101 - Protection of Minority Security Holders in Special Transactions ("MI 61-101"). Such insider

participation will be exempt from the formal valuation and minority shareholder approval requirements of MI 61-101

pursuant to sections 5.5(b) and 5.7(1)(a) of MI 61-101, as the Company is not listed on any of the exchanges or markets

outlined in subsection 5.5(b) of M I 61-101, and the fair market value of the securities to be distributed to the insiders will

not exceed 25% of the Company's market capitalization.

CONSOLIDATION

Immediately prior to the closing of the Offering, the Company plans to undertake the Consolidation, on the basis of five (5)

pre-Consolidation Shares for every one (1) post-Consolidation Share.

Prior to the Consolidation, and assuming completion of the Offering and exercise of pre-emptive rights in full by Nexa and

Buenaventura, the Company will have approximately 740,698,000 shares issued and outstanding. Following the

Consolidation and assuming completion of the Offering, the Company will have approximately 148,139,600 shares issued

and outstanding.

No fractional shares will be issued under the Consolidation. The holdings of any shareholder who would otherwise be

entitled to receive a fractional share as a result of the Consolidation shall be rounded down to the nearest whole number

and no cash consideration will be paid in respect of fractional shares. The Consolidation will not affect any shareholder's

percentage ownership in the Company other than by the minimal effect of the aforementioned elimination of fractional

shares, even though such ownershi p will be represented by a smaller number of shares. Instead, the Consolidation will

reduce proportionately the number of shares held by all shareholders.

3

A letter of transmittal will be mailed to registered shareholders providing instructions with respect to exchanging share

certificates representing pre-Consolidation Shares for post -Consolidation Shares. Shareholders who hold their shares in

brokerage accounts or in book-entry form are not required to take any action as they will have their holdings electronically

adjusted by the Company’s transfer agent or by their brokerage firms, banks, trust or other nominees. In accordance with

the Company’s articles of incorporation, the Consolidation will not require shareholder approval and was approved by the

Company’s Board of Directors on September 5, 2025.

The Company will issue a subsequent news release to announce the effective date of the Consolidation once approval has

been received from the Exchange, as the Consolidation remains subject to regulatory approval.

This news release does not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of any of

the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful. The securities have not been

and will not be registered under the United States Securities Act of 1933, as amended (the " U.S. Securities Act "), or the

securities laws of any state of the United States and may not be offered or sold within the United States (as defined in

Regulation S under the U.S. Securities Act) unless registered under the U.S. Securities Act and applicable state securities

laws or pursuant to an exemption from such registration requirements.

On behalf of the Board,

“Graham Carman”
