Metallic Minerals Corp. announce the completion of field activities at the Company's 100%-owned, 166 square kilometer Keno Silver project, adjacent to Hecla Mining in the high-grade Keno Hill silver district of Canada'sYukon Territory. The 2023 exploration program included 1,112 meters in four diamond drill holes focused on resource expansion at the Formo target, the highest-grade and largest target area to be included in an inaugural NI 43-101 mineral resource estimate for the property expected in Fourth Quarter 2023.

The Company also conducted additional soil geochemical sampling on open-ended earlier-stage targets for future drill campaigns. Metallic Minerals holds the second largest land position in the Keno district with claims covering the east, and parts of central and western Keno Hill, including eight high-grade, shallow past-producing deposits. Hecla Mining holds the western portion of the Keno district and has recently started production from its Keno Hill mining operations, with full production expected by year-end.

Keno Hill is one of the world's highest-grade silver districts, with nearly 300 million ounces ("Moz") of silver in past production and current M&I resources1,2 and featuring excellent existing infrastructure, including grid power, road access and nearby community services. In July 2022, Hecla Mining announced the acquisition of Alexco Resource Corp, which held the western portion of the district. Hecla Mining has started production at Keno Hill, which is now their highest-grade silver operation, and is expecting to be at full production by year end with a stated goal of producing 4-5 Moz of silver per year3.

Metallic Minerals' Keno Silver project is adjacent and contiguous with Hecla Mining ground, covering the east, and parts of the central and western Keno silver district and includes eight high-grade, shallow past-producing mines. Prior to the Company's consolidation of the land package, very little modern exploration had been completed in these parts of the district due to fragmented, private land ownership. Metallic Minerals has advanced four targets in the district from discovery to resource definition stage with several additional targets at drill-ready status along the known historically productive trends.

In addition, recent exploration has defined and expanded 12 priority multi-kilometer-scale early-stage targets for reconnaissance drilling in the under-explored parts of the district where highly elevated silver, lead and zinc in soils and high-grade rock samples have been identified.
