Metallic Minerals Provides Corporate and Project Update Including Key Catalysts for 2025

March 19, 2025 - Vancouver, BC - Metallic Minerals Corp. (TSX-V: MMG | OTCQB: MMNGF) ("Metallic Minerals"

or the "Company") is pleased to provide a corporate and project update covering the key goals and achievements

over the past year together with the outlook for anticipated catalysts in 2025 across its portfolio of projects in

established mining districts in Canada and the USA.

Key Corporate and Project Highlights:

• Released inaugural NI 43-101 Inferred Mineral Resource Estimate at the Keno Silver project of 18.2 million

ounces silver equivalent contained within 2.5 million tonnes with an average grade of 233 grams per tonne

(“g/t”) silver equivalent (120 g/t silver, 0.10 g/t gold, 0.80% lead and 1.77% zinc)1.

• Released results from 4,530 meters of a drill program at the La Plata project in Colorado funded by Newmont

Corporation's strategic 9.5% equity investment2.

• Undertook district-scale exploration and target prioritization work at the La Plata project in collaboration with

Newmont’s technical team to advance and prioritize new targets to a drill-ready status.

• Received additional royalty payments from gold production at the Australia Creek property in the Klondike

district of the Yukon with significant project development work to support expanded production in 2025.

• Appointed Dr. Stephen Enders, former Senior Vice President of Worldwide Exploration for Newmont, to the

Board of Directors.

Greg Johnson, Chairman & CEO of Metallic Minerals, stated, "We are very pleased with the significant

achievements across our portfolio over the past two years, highlighted by our inaugural inferred resource estimate

at Keno Silver and the strategic partnership with Newmont Corporation to advance our La Plata project. The

upcoming year promises to be transformative for Metallic Minerals as we anticipate key catalysts that include: an

updated resource estimate for La Plata, which will incorporate precious metals analyses not previously included,

results from our Keno Silver drill program, and continued growth in our gold royalty production in the Yukon. With

the large and mid-cap mining indices breaking above downtrend lines which extend back to the peak of the last

commodity cycle in 2011, there’s strong evidence that the sector has moved into a new cycle. Couple this with the

Venture Index which seems poised to follow, Metallic Minerals is exceptionally well-positioned to capitalize on

the favorable market dynamics for both copper and precious metals."

Corporate Developments

Metallic Minerals has made significant progress on the corporate front over the past two years, securing a strategic

9.5% equity investment from Newmont Corporation in 2023, followed by two subsequent top-up financings by

Newmont in 2024. The Company established a joint technical committee with Newmont to provide expertise and

collaboration on the La Plata project, leveraging Newmont's considerable experience with similar deposits in their

portfolio including their world-class Cadia and Red Chris mines. Additionally, the Company strengthened its board

of directors with the appointment of Dr. Stephen Enders, who brings valuable industry expertise from his previous

roles as Senior Vice President of Worldwide Exploration for Newmont, President of Phelps Dodge Exploration

Corporation, and Department Head for Geology and Geological and Mining Engineering at the Colorado School of

Mines.

La Plata Copper-Silver-Gold-PGE Project, Colorado USA

At the La Plata project, the Company released results in 2024 from 4,530 meters of diamond drilling funded by

Newmont's strategic investment. These results confirmed and extended significant copper-precious metals

mineralization with all holes intersecting continuous porphyry style mineralization over their entire length (up to

1,350 meters). The NI 43-101 Inferred Mineral Resource Estimate for the project defined 1.21 billion pounds of

copper and 17.6 million ounces of silver with 147.3 million tonnes at an average grade of 0.37% copper and 3.72

g/t silver (0.41% copper equivalent) using a 0.25% copper equivalent cut-off grade3.

Delays on lab results for platinum group element analyses have been resolved for surface samples and drill core

from La Plata. This data, along with results from the most recent drilling incorporating new geologic modelling of

the deposit are being incorporated in an updated mineral resource estimate anticipated to be completed in Q2-

2025. The updated resource estimate will include platinum, palladium and gold, in addition to copper and silver,

for the portion of the deposit that contains these elements.

Metallic Minerals completed extensive district-scale exploration and target prioritization work in 2024 in

collaboration with Newmont's technical team, resulting in the advancement of four new targets to a drill-ready

status, with over 20 additional target areas identified within the 25 square kilometer porphyry system footprint.

Results from this sampling and mapping work are being interpreted and are anticipated to be released in coming

weeks.

Working with researchers at Cardiff University, the Company has initiated mineralogical test work and analysis of

copper, silver, gold and platinum group metal mineralization at La Plata.

In addition, the USGS announced the release of its high-resolution airborne magnetic and radiometric survey over

the La Plata mining district. These surveys were completed as part of the USGS Earth Mapping Resource Initiative

focused on areas that have been identified as potential critical minerals resources for the United States. The La

Plata deposit hosts a suite of four elements including copper, platinum, palladium and tellurium, that are now

listed as critical minerals in the USA.

Metallic Minerals also held its first community open house events and launched a project website as part of its

engagement with the local stakeholders, communities, and tribal groups associated with the La Plata project.

Keno Silver Project, Yukon Territory

A major milestone at the Keno Silver project was the announcement of an inaugural NI 43-101 Inferred Mineral

Resource Estimate totaling 18.2 million ounces silver equivalent contained within 2.5 million tonnes at a grade of

223 g/t silver equivalent (120 g/t silver, 0.10 g/t gold, 0.80% lead and 1.77% zinc) across four separate deposits:

Formo, Fox, Caribou and Homestake1. Over 40 additional targets have been identified and advanced on the project

through surface sampling or drilling, which highlights the opportunities for continued new discoveries and the

development of new resource areas.

The Company also completed 718 meters of drilling in 2024, focusing on resource expansion at the Formo deposit

and advanced multiple new targets including the strategically located Rain and Shine prospect near Hecla Mining's

district mining and milling operations. Results from drilling and surface sampling will be released as part of an

upcoming Keno Silver project update in a future news release.

Klondike Gold Royalty Portfolio

Metallic Minerals is one of the largest owners of alluvial gold mining claims in the Yukon Territory and is focused

on building a portfolio of gold royalties in the historic Klondike Gold District to provide a revenue stream to

complement its exploration activities. The Company has realized royalty revenue from alluvial gold production in

both 2023 and 2024 and is seeking new operators for its significant additional claim holdings.

The Company has made substantial recent progress on new production royalty agreements and has completed

project infrastructure development to support increased production in 2025. Metallic Minerals has also initiated

the permit renewal process on its existing operations and has filed new applications on additional undeveloped

claims to support expanded royalty production.

Anticipated Catalysts for 2025

Results from surface sampling, mineralogical testing and an updated resource estimate for the La Plata project are

in process, as well as drill results from the Keno Silver project. In addition, planning is underway for exploration

programs in 2025 at La Plata, Keno Silver and the Klondike.

Near-term Catalysts (Q2 2025)

• District-wide surface sampling at La Plata showing development of high-priority drill targets in addition to

resource expansion potential at the Allard resource area.

• Mineralogical test work at la Plata in collaboration with researchers at Cardiff University.

• Updated resource estimate for La Plata incorporating recent drilling funded by Newmont. This update will

incorporate expanded precious metals analyses, including first inclusion of platinum, palladium and gold, in

addition to copper and silver, in the mineral resource estimate.

• Results from resource expansion drilling at Keno Silver.

Development Catalysts in 2025

• Planned exploration programs at both La Plata and Keno Silver projects.

• High potential for new discoveries and continued resource growth at both La Plata and Keno Silver.

• Anticipated increase in royalty production from Australia Creek operations and potential for new royalty

agreements.

Market Context and Commodity Outlook

The fundamental outlook for both copper and precious metals remains highly constructive. The large and mid-cap

mining indices are outperforming the general market, supporting that the sector has moved into the early stages

of a new major commodity cycle. The Venture Index, which is dominated by exploration and development

companies like Metallic Minerals, is also on the verge of breaking out and demonstrates the exceptional value

present in resource stage companies today.

Copper market dynamics are being driven by:

• Accelerating demand from global electrification and renewable energy adoption.

• Supply constraints from aging mines and lack of new major discoveries.

• Critical role in clean energy transition and infrastructure development.

Precious metals markets are supported by:

• Ongoing macroeconomic uncertainty and inflation concerns.

• Central bank purchasing activity.

• Supply-demand fundamentals particularly for copper and silver.

Metallic Minerals is well-positioned with its portfolio of copper and precious metals projects in top-tier North

American jurisdictions to capitalize on these favorable market dynamics through 2025.
