Metallic Minerals Appoints Dr. M. Stephen Enders to its Board of Directors

March 14, 2024 – Vancouver, BC – Metallic Minerals Corp. (TSX.V: MMG; OTCQB: MMNGF) (“Metallic Minerals” or

the “Company”) is pleased to announce that Dr. M. Stephen Enders has been appointed to the Company’s Board of

Directors. Steve brings over 47 years of experience in mineral exploration and mining, working on some of the world’s

most significant copper and gold deposits. Steve is a major addition to the Metallic team and the Company looks forward

to his invaluable contributions to the advancement of the La Plata copper-silver-gold-PGE and Keno Silver projects.

Steve’s distinguished career includes former positions as Senior Vice President of Worldwide Exploration for Newmont

Mining Corporation, the world’s largest gold company, and President of Phelps Dodge Exploration Corporation (now

Freeport McMoRan), one of the world’s largest copper companies. In addition, he was also a director of Copper

Mountain Mining Corp. (recently acquired by HudBay Mining) and former Executive Chairman, Director, and COO of

EMX Royalty Corporation. As a co-founder of Cupric Canyon Capital LLC, Steve has been part of the team that has

advanced the Khoemacau copper-silver mine in Botswana from exploration into production backed by private equity

investors.

In addition to his achievements in industry, Dr. Enders has served as

Department Head for Geology and Geological Engineering and for Mining

Engineering at the Colorado School of Mines until 2023 and is on the Board

of Governors for the CSM Foundation.

Dr. Enders is an Honorary Lecturer and past President of the Society of

Economic Geologists (SEG) as well as former President of the SEG Foundation

Board of Trustees. He received the Distinguished Achievement Medal from

the Colorado School of Mines in 2009, the Ben F. Dickerson Award from the

Society for Mining, Metallurgy & Exploration in 2014, and the Ralph W.

Marsden Award from the Society of Economic Geologists in 2016.

Dr. Enders holds a BSc degree in geological engineering from the Colorado School of Mines and MSc and PhD degrees

from the University of Arizona.

Metallic Minerals Chairman and CEO, Greg Johnson, stated, “We are very pleased to welcome Steve to the Metallic

Minerals Board of Directors. Steve’s depth of technical experience in exploration and development of major copper and

gold deposits and mines worldwide with companies such as Newmont and Phelps Dodge, along with his hands on

entrepreneurial experience in high-growth opportunities is a terrific addition to our board’s current expertise in deposit

discovery and advancement, process engineering, mine building and project financing.”

Steve Enders stated, “I am excited by the opportunity to help Metallic Minerals advance the La Plata discovery. It is

rare indeed today to find an outcropping porphyry copper deposit that has not yet been mined. The presence of high-

grade copper mineralization with precious metal credits is promising for a potential underground mine that could be

developed in the future with a net positive impact for all stakeholders.”

Grant of Long-Term Performance Incentives

Metallic Minerals further announces that, subject to the approval of the TSX Venture Exchange, it has granted 1,875,000

stock options (each, an “Option”) to certain directors, officers and employees of the Company in accordance with the

Company’s Long-Term Performance Incentive Plan. Each Option is exercisable into one common share in the capital of

the Company (“Share”) at a price of $0.30 per share, being the closing price of the Shares on the TSX Venture Exchange

on March 13, 2024, for a period of five years from the date of grant. The Options are subject to certain vesting

requirements in accordance with the shareholder approved plan.

About Metallic Minerals

Metallic Minerals Corp. is a Canadian exploration and development stage company, focused on copper, silver, gold, and

Klondike districts of the Yukon. Our objective is to create shareholder value through a systematic, entrepreneurial

At the Company’s La Plata project in southwestern Colorado, the expanded 2023 NI 43-101 mineral resource estimate

highlights a significant porphyry copper-silver resource containing 1.2 Blbs copper and 17.6 Moz of silver with numerous

additional targets showing potential for a district scale porphyry corridor. Drill results announced in early 2023 included

the longest and highest-grade interval ever encountered at La Plata and one of the top intersections for any North

American copper project in the past several years. In May 2023, the Company announced a 9.5% strategic investment

by Newcrest Mining Limited (acquired by Newmont Corporation in November 2023) to accelerate the advancement of

the La Plata project. A 4,500-meter drill program focused on expanding the current mineral resource and testing

extensions of strong porphyry-style mineralization was completed in December 2023 with results pending. In the 2023

Fraser Institute’s Annual Survey of Mining Companies, Colorado ranked 5th globally for investment attractiveness and

2nd in the USA.

In Canada’s Yukon Territory, Metallic Minerals has consolidated the second-largest land position in the historic high-

grade Keno Hill silver district, directly adjacent to Hecla Mining Company’s operations, with more than 300 Moz of high-

grade silver in past production and current M&I resources1,2. The new 2024 Resource Estimate at the Company’s Keno

Silver Project adds 18.16 Moz silver equivalent ounces3 to the district3. Hecla, the largest primary silver producer in the

USA and third largest in the world, is anticipating full production at its Keno Hill operations in 20242.

The Company is also one of the largest holders of alluvial gold claims in the Yukon and is building a production royalty

business by partnering with experienced mining operators, including Parker Schnabel of Little Flake Mining from the

Discovery Channel show Gold Rush.

All of the districts in which Metallic Minerals operates have seen significant mineral production and have existing

infrastructure, including power and road access. Metallic Minerals is led by a team with a track record of discovery and

exploration success on several major precious and base metal deposits in the region, as well as having large-scale

development, permitting and project financing expertise. The Metallic Minerals team has been recognized for its

environmental stewardship practices and is committed to responsible and sustainable resource development.
