MTB Metals Arranges Flow Through Placement

Vancouver, B.C. August 12, 2025 - MTB Metals Corp. ("MTB" or the "Company") (TSX.V: MTB, OTCQB: MBYMF, Frankfurt: M9U) is pleased to announce that it has arranged a flow through private placement for up to $300,000 priced at $0.025 per unit, consisting of one share on a flow-through basis and one half of a warrant, exercisable for 18 months at $0.05 into a non-flow-through share. The proceeds will be used exclusively to advance the Company's Telegraph and Southmore projects. Up to $80,000 of the proceeds may be paid to non-arms-length parties for exploration services in the normal course of business.

Lawrence Roulston, CEO commented: "The further work on our two high potential projects will add considerable value and bring us closer to having joint venture partners to fund future work."

About MTB Metals:

MTB is advancing two copper-gold projects in the prolific Golden Triangle of northern British Columbia:

Telegraph: MTB controls 350 square kilometres of property located in the vicinity of 4 notable porphyry deposits being advanced by major mining companies: Galore (Teck/Newmont), Schaft (Teck), Saddle (Newmont) and the operating Red Chris copper-gold mine (Newmont). Field work by MTB, together with earlier results, provides compelling evidence for the presence of one or more porphyries, similar to others in the area. MTB has an option to earn 60% of claims representing 27% of the property and controls 100% of the balance of the property.

Southmore: 50 square kilometer property hosts several significant copper and gold occurrences. Surface samples include a sample with 12.7% copper and another with 29.4 g/t gold.

MTB also holds royalties on four projects in the Golden Triangle, including two past producing mines and it holds 480,072 shares of Dolly Varden Silver.

NEITHER TSX VENTURE EXCHANGE NOR ITS REGULATION SERVICES PROVIDER (AS THAT TERM IS DEFINED IN THE POLICIES OF THE TSX VENTURE EXCHANGE) ACCEPTS RESPONSIBILITY FOR THE ADEQUACY OR ACCURACY OF THIS RELEASE.

This news release includes certain statements and information that may constitute forward-looking information within the meaning of applicable Canadian securities laws. Forward-looking statements relate to future events or future performance and reflect the expectations or beliefs of management of the Company regarding future events. Generally, forward-looking statements and information can be identified by the use of forward-looking terminology such as "intends" or "anticipates", or variations of such words and phrases or statements that certain actions, events or results "may", "could", "should", "would" or "occur". This information and these statements, referred to herein as "forward-looking statements", are not historical facts, are made as of the date of this news release and include without limitation, statements regarding discussions of future plans, estimates and forecasts and statements as to management's expectations and intentions with respect to, among other things, the exploration of the Company's properties and the benefits the Company will derive from the sale of certain non-core exploration projects to Dolly Varden.

These forward-looking statements involve numerous risks and uncertainties and actual results might differ materially from results suggested in any forward-looking statements. These risks and uncertainties include, among other things, that the Company will not receive the necessary regulatory approvals in respect of the sale of certain non-core exploration projects, that the Company will not continue to focus on its Telegraph porphyry copper-gold project, that the Company's shareholders will not benefit from exploration success on the sold properties, that the Company will not continue to advance its Southmore copper-gold project or that it will be unable to secure a joint venture partner to fund further work at Southmore, and that the Company is not well positioned to unlock the value of the copper-gold system at the Telegraph porphyry copper-gold project.

In making the forward looking statements in this news release, the Company has applied several material assumptions, including without limitation, that the Company will receive the necessary regulatory approvals in respect of the sale of certain non-core exploration projects, that the Company's exploration plans will align with management's current expectations, that the Company will derive the benefits from the sale of the properties currently anticipated, and that the Company will secure a joint venture partner to further work at Southmore.

Although management of the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements or forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements and forward-looking information. Readers are cautioned that reliance on such information may not be appropriate for other purposes. The Company does not undertake to update any forward-looking statement, forward-looking information or financial out-look that are incorporated by reference herein, except in accordance with applicable securities laws.
