Metallic Minerals Announces Surface Sampling Results with up to 988 g/t Silver and 24.4 g/t Gold from McKay Hill Project in the Yukon Territory

Vancouver, British Columbia--(Newsfile Corp. - October 24, 2017) - Metallic Minerals Corp. (TSXV: MMG) (OTC Pink: MMNGF) ("Metallic Minerals" or the "Company") is pleased to announce results from field exploration programs conducted at its 100% owned McKay Hill silver and gold project, located 50 kilometers ("km") north of the historic Keno Hill silver district, adjacent to ATAC Resources Ltd.'s Rackla Gold project in Canada's Yukon Territory (see Figure 1 below).

The McKay Hill project occurs within a belt of silver-lead-zinc related deposits that stretch from the Alaska border to the southern part of the Yukon and includes the famous Keno Hill silver district. McKay Hill is an historic high-grade producer that shows potential to host a significant district scale vein system similar to Keno Hill, with at least 16 identified vein structures that have seen very limited modern exploration. McKay Hill was discovered in the 1920s and worked on between 1926-29, including a shallow drill program by Consolidated Mining and Smelting Company of Canada (now Teck Resources Limited). Between 1948 and 1949, East Bay Gold produced 143 tonnes of high-grade material from the No. 6 vein at McKay Hill, grading 390.8 g/t Ag and 74.1% Pb.¹

Historic surface sampling at McKay Hill returned high-grade silver, lead and zinc mineralization associated with vein structures. More recent field work conducted by Metallic Minerals, and its predecessor, confirmed these historic high grades of silver, lead and zinc and also demonstrated the presence of significant associated gold and copper values. Exploration work in 2017 included follow up rock and soil sampling, reconnaissance and detailed mapping of veins in the Central Zone and Independence Ridge areas. In addition, high resolution satellite photography was collected over the entire property to provide mapping and topographic ground control for use in future programs. Soil sampling extended the existing soil grid in the Central Zone to cover open anomalies and a new soil grid was established at the Independence Ridge area. Mapping and prospecting noted some distinctive hydrothermal and structural characteristics to the mineralization, which suggests the potential for a large mineralized system.

Most of the exploration at McKay Hill to date has been conducted on the Central Zone where veins No. 1 to 9, Bella, Blackhawk and Snowdrift occur near the area of historic production. Much of the claim block remains under-explored, including in the Independence Ridge area to the east of the Central Zone, where at least four vein zones are exposed. Additional vein targets occur to the north and west of the Central Zone near the Falls, Red, and White Hill targets. Highlights from sampling to date at McKay Hill are shown below in Table 1, with 2017 samples denoted by an asterisk. Tables 2 and 3 provide a comprehensive summary of all significant rock sample results collected to date on the property. The locations of these samples are shown on Figure 2.

Table 1 - Highlight Rock Sample Values to Date from McKay Hill:

Greg Johnson, CEO & Chairman stated, "We are very encouraged by the results we have seen thus far from McKay Hill with 23 samples from 12 of the 16 known vein structures running greater than 300 g/t silver, which is the average reserve grade of global primary silver producers². The assay results from rock sampling and soil grid work have verified the potential for high-grade silver, lead, and zinc mineralization, as well as demonstrated very significant gold and copper in this emerging district scale property. Two distinct soil anomalies remain open to further expansion covering more than 1.5 kms of total length with elevated silver, gold, lead, zinc and copper values. Results from the SkyTEM EM survey in Figure 3 show several additional areas on the property with similar geophysical characteristics to the Central Zone. Based on our initial results, additional field work has been conducted this month to extend soil sampling over mineralized areas that remain open to expansion and further staking was undertaken to expand the property by another 20% to 35.4 km². The results from McKay Hill support continued work on the project in 2018 and we are excited to have a second property in our portfolio that is advancing to the drill testing stage, substantiating the potential to develop numerous high-grade drill targets."

McKay Hill Project Next Steps

The information provided by the 2017 field program, and a comprehensive review of historic data, has enabled the Metallic Minerals technical team to begin developing future programs which are expected to commence in 2018 and consist of:

1. Additional prospecting and surface geochemical sampling on areas of the property not covered to date, particularly over the identified geophysical targets (see Figure 3);

2. Mapping over the expanded soil grids and chip sampling of newly identified vein occurrences;

3. Expansion of the existing soil grids of the Central Zone and Independence Ridge areas where the anomalous trends remain open;

4. Trenching and geophysical surveys to define and prioritize potential drill targets on the most advanced prospects including the No. 1, 6, and 8 veins, and the Snowdrift, Blackhawk and Independence veins; and

5. Potential drilling on the most advanced targets identified through preliminary surface work.

Keno Silver Project Update

The 2017 field exploration program at the Company's flagship high-grade Keno Silver Project, adjacent to Alexco Resource Corp., in the Keno Hill silver district was completed in September. All materials from surface sampling, trenching and drilling have been sent for analysis. Assay results are anticipated in the coming weeks, following one of the busiest Yukon exploration seasons in years.

Quality Assurance / Quality Control

Analytical work in 2017 was done by Bureau Veritas Commodities Canada Ltd. with sample preparation in Whitehorse, Yukon and geochemical analysis in Vancouver, British Columbia. Each rock (grab) sample was analyzed for 36 elements using an Aqua Regia digestion with inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and inductively coupled Plasma-mass spectrometry (ICP-MS) (AQ202). Samples with over limit silver and gold were re-analyzed using a 30-gram fire assay fusion with a gravimetric finish (FA530-Ag, Au). Over-limit lead and zinc samples were analyzed by multi-acid digestion and atomic absorption spectrometry (MA404) or titration (GC516, GC8917). All results have passed the QAQC screening by the lab.
