Metallic Minerals Announces Start of Drilling at La Plata Silver-Gold-Copper Project in Southwest Colorado, USA, and Extends Warrant Expiry

VANCOUVER, BC / ACCESSWIRE / July 27, 2022 / Metallic Minerals (TSX.V:MMG)(OTCQB:MMNGF) ("Metallic Minerals", or the "Company") is pleased to announce the start of its 2022 exploration and drill campaign at the La Plata silver-gold-copper project, located in southwest Colorado. This is the Company's second diamond core drill program at La Plata and follows the establishment of a new NI 43-101 compliant mineral resource estimate announced earlier this year (see news release dated April 26, 2022).

The initial focus of the 2022 drill program is to extend the limits of previously drill-identified mineralization in the Allard resource area, which is expected to form the basis for updated and expanded resource estimate in 2023. The Company is in the process of completing a follow-up ground-based induced polarization geophysical survey designed to support resource expansion drilling, as well as to help refine and prioritize additional copper-silver-gold porphyry targets developed from the Company's systematic exploration and the application of new technologies on the project.

La Plata Project Highlights

• Inaugural National Instrument 43-101 ("NI 43-101") compliant inferred mineral resource issued April 2022 for the Allard deposit totals 889 million pounds of copper and 15 million ounces of silver in a constrained model, with 115.7 million tonnes at an average grade of 0.39% copper equivalent ("Cu Eq") (0.35% Cu and 4.02 g/t Ag) using a 0.25% Cu Eq cut-off grade¹.
• Drilling highlights at the Allard porphyry system include 395 m grading 0.57% copper equivalent (0.51% Cu, 6.3 g/t Ag and 0.017 g/t Au) in LP-03, and 854 m at 0.26% Cu, including 254 m grading 0.41% Cu, in drill hole LP-01. Both drill holes started and ended in mineralization.
• Exploration drilling in 2022 is designed to expand limits of known mineralization in the Allard resource area and to test newly developed targets representing potential new copper-silver-gold porphyry mineralization.

Project History

The road accessible La Plata project covers 33 km² approximately 20 km northeast of Mancos, Colorado within the historic high-grade La Plata mining district located at the southwest end of the prolific Colorado Mineral Belt. Mineralization is related to a large-scale precious metals-rich porphyry copper system with associated high-grade silver and gold epithermal vein and replacement deposits.

The La Plata district has a long and rich history of mining with the first silver deposits discovered in the 1700s by Spanish explorers. High-grade silver and gold production has been documented from the 1870s through the early 1940s from vein structures, replacement bodies and breccia zones at over 90 individual mines and prospects³. From the 1950s to 1970s, major miners including Rio Tinto (Bear Creek) and Freeport-McMoRan (Phelps Dodge) explored the district focusing on the significant potential for bulk-tonnage disseminated and stockwork hosted mineralization². Freeport-McMoRan retained ownership of claims in the district until 2002 when they sold their holdings to the current underlying vendors during the lows of the last metal price cycle.

A total of 56 drill holes totaling 15,200 m have been drilled on the property since the 1950s which confirm the presence of large multi-phase porphyry system with significant silver, gold and copper. This large-scale mineralized system is associated with a 10 km² strongly magnetic signature with intense hydrothermal alteration. Surrounding the central porphyry system is an associated high-grade silver and gold-rich epithermal system measuring at least 8 km by 2 km that hosts 56 identified vein, replacement, and breccia structures. Historical production from some of these high-grade structures included bonanza grades for silver and gold².

In addition to the development of the inaugural resource estimate, exploration completed by Metallic Minerals at La Plata to date has included confirmation drilling, resampling of historic drill core and underground sampling, surface mapping, and soil sampling. The Company has also completed comprehensive geophysical surveys over the project including airborne resistivity and magnetics, ground-based induced polarization surveys, and analysis of multi-spectral remote sensing data to establish mineralized anomalies and domains for the various styles of mineralization. This work has identified 16 untested potential porphyry centers outside of the main Allard resource area, as well as developed targets with potential for significant high-grade epithermal silver and gold.

Warrant Extension

Metallic further announces that the Company has applied to the TSX Venture Exchange for approval to extend the expiry date on 9,587,500 warrants that were due to expire August 13, 2022 (the "Warrants") to February 13, 2023. The Warrants were originally issued as part of a financing completed in August 2020 (see news release dated August 13, 2020) led by Canaccord Genuity Corp. on behalf of a syndicate of underwriters including Red Cloud Securities Inc. and Mackie Research Capital Corporation. The warrants entitle the holder to acquire one common share at an exercise price of $0.60.

About Metallic Minerals

Metallic Minerals Corp. is an exploration and development stage company, focused on silver, gold and copper in the high-grade Keno Hill and La Plata mining districts of North America. Our objective is to create shareholder value through a systematic, entrepreneurial approach to making exploration discoveries, growing resources and advancing projects toward development. Metallic Minerals has consolidated the second-largest land position in the historic Keno Hill silver district of Canada's Yukon Territory, directly adjacent to Alexco Resource Corp's operations, with more than 300 million ounces of high-grade silver in past production and current M&I resources. Hecla Mining Company, the largest primary silver producer in the USA and fourth largest in the world, announced the acquisition of Alexco in July 2022. Metallic recently announced the inaugural NI 43-101 mineral resource estimate for its La Plata silver-gold-copper project in southwestern Colorado. The Company also continues to add new production royalty leases on its holdings in the Klondike gold district in the Yukon. All three districts 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, as well as having large-scale development, permitting and project financing expertise.

Footnotes

1) See Technical Report on the Inaugural Mineral Resource Estimate for the Allard Cu-Ag Porphyry Deposit, La Plata Project, Colorado, USA with an effective date of April 3, 2022. The Mineral Resource has been estimated in conformity with CIM Estimation of Mineral Resource and Mineral Reserve Best Practices Guidelines (2019) and current CIM Definition Standards - For Mineral Resources and Mineral Reserves (2014). The constrained Mineral Resources are reported at a base case cut-off grade of 0.25% CuEq, based on metal prices of $3.60/lb Cu and $22.50/oz Ag, assumed metal recoveries of 90% for Cu and 65% for Ag, a mining cost of US$5.30/t rock and processing and G&A cost of US$11.50/t mineralized material. (1) Cu Eq* calculations are based on 100% recovery of all metals using the same metal prices used for the resource calculation. All figures are rounded to reflect the relative accuracy of the estimate. The current Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability. The quantity and grade of reported Inferred Resources in this Mineral Resource Estimate are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as Indicated or Measured. However, based on the current knowledge of the deposits, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
