VANCOUVER, BC / ACCESSWIRE / September 14, 2023 / Metallic Minerals Corp. (TSX.V:MMG)(OTCQB:MMNGF) ("Metallic Minerals" or the "Company") is pleased to provide an update on drilling at the La Plata copper-silver-gold-PGE project. The first phase of the 2023 campaign is testing extensions of high-grade mineralization seen in 2022 drill hole LAP22-04, which intercepted 816 meters of continuous mineralization grading 0.41% copper equivalent ("Cu Eq") with internal higher-grade zones. The hole ended in high-grade precious metal-rich mineralization grading 11.54% Cu Eq over 0.61 meters (5.42% Cu, 47.0 g/t Ag, 0.622 g/t Au, 5.016 g/t Pt and 5.393 g/t Pt).

Highlights

• Over 2,000 meters of a planned 5,000-meter Phase 1 drill program designed to expand the existing resource have been completed.
• Hole LAP23-05 was completed to a depth of 909 meters, while hole LAP23-06 is ongoing at a depth of approximately 1,150 meters. Both these 2023 drill holes have intersected altered porphyry mineralization with visible copper sulfide including chalcopyrite and bornite similar to that seen in LAP22-04 (see Figure 1-2).
• Initial assay results are expected in the coming weeks and continuing into early 2024.
• Results of the 2023 drilling have potential to expand the size of the current resource and increase the overall grade of the deposit with the inclusion of precious metals assays for gold, platinum and palladium in addition to copper and silver in the current resource.
• Metallic Minerals has filed a National Instrument 43-101 technical report for the expanded resource estimate announced in July 2023.
• The 2023 field campaign is being funded by a strategic equity investment announced in May whereby Newcrest Mining Limited acquired a 9.5% ownership position in Metallic Minerals with the goal of accelerating advancement of the La Plata project.

Scott Petsel, Metallic Minerals' President, stated, "The team is excited about the progress and initial indications from our current drill program at La Plata. Last year's exceptional hole LAP22-04 was a major discovery of higher-grade copper and precious metal-rich, porphyry-style, mineralization starting from surface. These first two drill holes are offset holes drilled above and below LAP22-04 to test extensions of mineralization away from that discovery hole to potentially expand the resource and test the scale of size of this higher-grade zone of mineralization. The results of this program are expected to form the basis of an updated resource estimate. This program will also assist in vectoring to the strongest parts of the mineralized system as we work to maximize the opportunity to advance this potential Tier 1 asset."

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 km², remains underexplored with the potential for new discoveries of both additional copper porphyry centers, as well as high-grade epithermal silver and gold systems.

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 projects toward development.

At the Company's La Plata project in southwestern Colorado, the new 2023 NI 43-101 mineral resource estimate identifies a significant porphyry copper-silver resource containing 1.21 Blbs copper and 17.6 Moz of silver¹. The 2022 expansion drilling provided the basis for the updated resource, including 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 to accelerate the advancement of the Company's La Plata project. 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 ("Hecla") operations, with more than 300 Moz of high-grade silver in past production and current M&I resources. Hecla, the largest primary silver producer in the USA and third largest in the world, is anticipating full production at its Keno Hill operations by the end of 2023. An inaugural mineral resource estimate on the project is expected in Q4 2023, with an expansion drill program slated to commence in September.

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 television 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. The Company 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.
