Metallic Minerals Launches First Phase Drill Program at the La Plata Copper-Silver-Gold-PGE Project in

Southwest Colorado, USA

July 11, 2023 – Vancouver, BC – Metallic Minerals Corp. (TSX.V: MMG; OTCQB: MMNGF) (“Metallic Minerals” or the

“Company”) is pleased to announce the start of the 2023 exploration and drill campaign at the La Plata copper-silver-

gold-PGE project, located in southwest Colorado.

In May 2023, Newcrest Mining Limited completed a 9.5% strategic equity investment into Metallic Minerals with the

goal of accelerating advancement of the La Plata porphyry project. This funding will support a two-phase drill campaign

in 2023 that will build on the success from work in 2022. The initial phase is expected to consist of approximately 5,000

meters of diamond core drilling, primarily focused on resource expansion at the Allard porphyry deposit.

A top p riority for the program will be to conduct step-out drilling from the major discovery in drill hole 22 -04 which

intersected 816 meters of 0.41% Cu Eq (0.30% Cu, 2.47 g/t Ag, 0.038 g/t Au, 0.055 g/t Pd and 0.093 g/t Pd) from

surface and ended in 5.39% CuEq over 5.2 m (2.44% Cu, 18.7 g/t Ag, 5.0 g/t Au+PGE). Hole 22-04 did not reach target

depth and ended in mineralization due to mechanical issues. Drilling in 2023 will test the lower limits of mineralization

and some holes are scheduled for as deep as 1,200 meters.

Scott Petsel, Metallic Minerals’ President, stated, “We see a real opportunity for world class scale and grade at La Plata

and have confidence in our ability to quickly grow the existing resources. Hole 22-04 was not only the widest and highest-

grade drill hole ever drilled on the project, it was also one of the top holes drilled in the last several years at any copper

project in North America. We also expect to be able to increase the overall grade of the resource moving forward as we

include precious metals credits previously not accounted for. Our exploration work over the past two years has defined

16 additional untested porphyry targets across the greater property, which appear to have very similar characteristics

to the Allard deposit and could result in additional new discoveries. The drill is currently mobilizing to site.”

The Allard deposit remains open to significant expansion within the resource area to the east, north and west and to

depth, with the potential to add gold, platinum and palladium to the current copper and silver resource with the

completion of additional exploration drilling. In addition, the larger porphyry system at the La Plata project, which covers

an area of over 10 km 2, remains underexplored with the potential for new discoveries of both additional copper

porphyry centers, as well as high-grade epithermal silver and gold systems.

Yukon Mining Alliance 2023 Property Tours

Metallic Minerals will be participating in the Yukon Mining Alliance Property Tours and Investment Conference in

Dawson City on July 19th. Select tour participants will visit Metallic’s Australia Creek alluvial gold royalty property in the

Klondike Gold District, currently under lease to Parker Schnabel’s Little Flake Mining as seen on Discovery Channel’s

Gold Rush television program. More information whereabout the YMA Property Tours and Conference can be found

About Metallic Minerals

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

other critical minerals in the La Plata mining district in Colorado, and silver and gold in the high-grade Keno Hill and

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

approach to making exploration discoveries, growing resources, and advancing our projects toward development.

In 2023, the Company announced a 9.5% strategic investment by Newcrest Mining Limited for the continued

advancement of the Company’s La Plata project in southwestern Colorado. The inaugural NI 43-101 mineral resource

estimate, announced in 2022, identified a significant porphyry copper-silver resource containing 889 Mlbs copper and

15 Moz of silver and an updated estimate is currently being finalized. Notably, Colorado was recently ranked 5th globally

for investment attractiveness and 2nd in the USA In the 2023 Fraser Institute’s Annual Survey of Mining Companies.

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’s operations, with more than 300 Moz of high-grade

silver in past production and current M&I resources. Hecla Mining Company, the largest primary silver producer in the

USA and third largest in the world, completed the acquisition of Alexco Resources and their Keno Hill operations in

September 2022. Hecla is targeting to start production at the Keno Hill operations by Q3 2023. Metallic Minerals is

anticipating the announcement of inaugural mineral resource estimate at Keno Silver in the second half of 2023.

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 hit

television show, Gold Rush, on the Discovery Channel.

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, 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.
