April 10, 2023 – Vancouver, BC – Metallic Minerals Corp. (TSX.V: MMG; OTCQB: MMNGF) (“Metallic Minerals” or the “Company”) is pleased to announce final results from the 2022 exploration program at its 100% owned high-grade Keno Silver project in the historic Keno Silver District of Yukon, Canada. A total of 642 meters (m) were drilled in six (6) holes at the Caribou target in the Central Keno area to test extensions of known high-grade and bulk-tonnage mineralization. This work was completed as part of a larger 3,265 m drill program focused on target extension drilling at our advanced-stage “resource-ready” targets (Caribou, Formo and Fox) in anticipation of an inaugural NI 43-101 mineral resource estimate for the Keno Silver project in 2023.
- Drilling at the Caribou target continues to successfully extend high-grade silver mineralization both down-dip and south along strike of the known extents of the Caribou structure with a total of 71 intercepts in 5,980 meters of drilling to date.
- Hole CH22-01 intersected two separate higher grade vein intervals within a broad zone of bulk tonnage mineralization. From 91.5 to 92.0 meters a 0.5 m interval contained 348 (g/t) silver equivalent (“AgEq”) (see Table 1, Footnote 1) and 125.2 to 125.7 m the hole intercepted 0.5 m of 1,201 g/t Ag Eq bounding a zone of 34.2 m grading 38 g/t Ag Eq.
- The southernmost drilling at the Caribou target, first drilled in 2021, continues to demonstrate strong potential for further extension with 1,310 g/t Ag Eq encountered over 0.5 m at a near-surface depth of 44 m in hole CH22-05.
- The Company has retained SGS Geological Services to complete the inaugural resource estimate and modelling work is underway.
Metallic Minerals President, Scott Petsel, stated, “The Caribou vein target in the Central Keno Area is a classic example of “Keno-style” high-grade Ag-Pb-Zn vein mineralization and shows excellent potential for resources of significant scale. As one of five near-term resource targets on the property, Caribou has consistently returned grades over 1,000 g/t Ag Eq and, more recently, has been recognized as a potential bulk tonnage target returning widths of mineralization up to 34.2 meters of potentially economic grades in a shallowly dipping configuration.”
“With high-grade results at the Caribou, Formo and Fox area targets, along with the continued delineation of broad bulk tonnage mineralization near surface, we are continuing to demonstrate the extensive exploration potential of the district. We look forward to completing a first resource for the Keno Silver project in the second half of 2023 and are also expecting to announce a resource update on our La Plata Project in Colorado in Q2, following the exceptional drill results announced on February 28th, 2023.”

Central Keno Hill Silver District
The central part of the Keno Hill Silver District is host to over 100 million ounces of past production and current Indicated resources in shallow deposits that, to date, have not previously seen systematic exploration to depth or along strike. Central Keno was one of the original discovery areas in the region and hosted the historic producing Keno Hill mine, along with eight other high-grade deposits including those on Metallic Minerals land holdings. Metallic Minerals’ work to date in this area shows the presence of a major structural corridor that is comparable in surface expression and structural setting to the +150 million-ounce Bermingham-Calumet system in the extensively explored western part of the district.
Caribou Target Area
The road accessible Caribou target in the central part of the district is one of the most advanced individual targets at the Keno Silver project. Eighty-three (83) drill holes totalling 5,980 m (a 72 m average hole depth), have been drilled since 2008 at Caribou making it the Keno Silver project’s most drilled target area. The Caribou deposit historically produced very high-grade material grading more than 1,000 g/t silver from near surface and is interpreted to be a significant connecting structure between the main shear structures in the Keno Summit structural corridor. The Caribou deposit spatially occurs within a high-level silver-in-soil anomaly of over 10 g/t Ag Eq that extends over 2.5 km long by 1.5 km in width and that remains open to expansion.
Figure 1 – Keno Silver District Geology and Deposits
Mineralization at the Caribou target consists of high-grade, north-striking Ag-Pb-Zn structures with a shallow 34-degree dip. Exploration on the high-grade vein structure has also defined a surrounding envelope of broader bulk tonnage mineralization. These broader zones of mineralization not only include wide veins but also parallel veinlets, stringers and breccia zones. In the 2021 and 2022 drilling of the broader Caribou zone returned intervals up to 34.2 m wide (averaging 18.2 m), with grades between 35.2 g/t Ag Eq and 134 g/t Ag Eq. These wide widths combined with a shallow dip and a near surface environment (deepest intercept is only 120 m from surface), make this bulk tonnage and high-grade mineralization potentially amendable to low cost, bulk tonnage mining methods.
Similarly, the Fox and Formo targets also show broader zones of mineralization that may be amenable to lower cost mining methods, as was successfully demonstrated in the Keno District at the Hector Calumet and Onek deposits by United Keno Hill Mines in the 1980s1.

Ag Eq (g/t)
Notes to reported values:
- Ag equivalent is presented for comparative purposes using conservative long-term metal prices (all USD): $20.0/oz silver (Ag), $1,800/oz gold (Au), $1.00/lb lead (Pb), $1.40/lb zinc (Zn).
- Recovered Silver Equivalent in Table 1 is determined as follows: Ag Eq g/t = [Ag g/t x recovery] + [Au g/t x recovery x Au price/ Ag price] + [Pb % / 10,000 x recovery x Pb price / Ag price] + [Zn% / 10,000 x recovery x Zn price / Ag price].
- In the above calculations: 1% = 10,000 ppm = 10,000 g/t.
- The following recoveries have been assumed for purposes of the above equivalent calculations: 95% for precious metals (Ag/Au) and 90% for all other listed metals, based on recoveries at similar nearby operations.
- Intervals are reported as measured drill intersect lengths and may not represent true width.

Recap of 2022 Exploration at the Keno Silver Project
Metallic Minerals completed 3,265 m meters of diamond drilling in 23 holes at the Keno Silver Project during 2022 with the aim of extending advanced-stage “resource-ready” targets in anticipation of an inaugural resource estimate for the project in 2023. Additionally, LiDAR data collection and ground based geophysics were completed to further support project advancement and target generation.
These final Caribou results from drilling during the 2022 field exploration program caps-off what was an exceptional year at the Keno Silver Project with 138 significant intervals of greater than 100 g/t Ag Eq and 22 intervals over 500 g/t Ag Eq drilled within 23 holes. A robust drill program focused on continued resource expansion and to test new targets is being planned for 2023.
