Metallic Minerals Reports High-Grade Silver, Lead, Zinc, and Copper Results from 2018 Exploration Program at the McKay Hill Project in Yukon Territory
VANCOUVER, British Columbia, Jan. 28, 2019 (GLOBE NEWSWIRE) -- Metallic Minerals Corp. (TSX-V: MMG;
Although earlier stage than the Company’s Keno Silver Project to the south, Metallic see’s similar potential for a district scale high-grade silver-lead-zinc-copper system at McKay Hill based on results to date including:
- Total of 37 vein structures identified on the property to date, with the discovery of 18 new silver-lead-zinc-rich structures in 2018, with 61 samples ranging 1,000 to 4,326 g/t silver equivalent;
- The outline of six kilometer-scale areas of highly elevated silver, lead, zinc, copper and gold in soils and rock sampling; and
- Advancement of the Central Zone targets to drill-ready stage along with demonstration of the potential to host bulk-tonnage mineralization.
The McKay Hill Project occurs within a belt of silver-lead-zinc related deposits that stretches from the Alaska border to the southern part of the Yukon and includes the famous Keno Hill Silver District. McKay Hill was discovered in the 1920s and had production in the 1940s of high-grade material from the No. 6 Vein Corridor grading 390.8 g/t Ag and 74.1% Pb.1 With at least 37 vein structures (including the 18 new structures discovered in 2018) which have only seen limited exploration, the area shows potential to host a significant district-scale vein system similar to Keno Hill.
Metallic CEO and Chairman, Greg Johnson, stated,
"We are very pleased to report these additional rock and trenching results from our 2018 exploration program at the McKay Hill Project, which significantly advanced the project with 18 newly defined vein structures, including some spectacular bonanza grades. To date, a total of 61 rock samples have exceeded 1,000 g/t silver equivalent values with values up to 4,326 g/t silver equivalent in rock samples and up to 2,126 g/t silver equivalent over 2 meters in channel sampling. Work in 2018 has identified 6 separate kilometric-scale target areas with high-grade silver values along with associated lead, zinc and copper mineralization covering an area approximately 3 kilometers by 1.5 kilometers wide in soil and rock sampling (See news release December 4th, 2018, Metallic Minerals Identifies Multiple Kilometer-long Anomalies at McKay Hill, Yukon Territory). These results have significantly expanded the areas of known mineralization but cover only a small portion of the 44 square kilometer property, supporting the potential for the discovery of additional mineralized targets in future programs. This year’s program successfully achieved the key objectives of expansion of the main Central Zone target through trench, rock and soil sampling and identifying and refining six additional kilometric-scale target zones, including the West McKay, Bella, Red, Falls and Snowdrift and Independence Zones (see Figure 1). A comprehensive exploration program is being planned for 2019 at McKay Hill in coordination with the Company’s Keno Silver Project exploration activities. We look forward to providing additional updates on Metallic’s portfolio of projects in coming weeks.”
Central Zone Target Area
The Central Zone was the focus of historic exploration, and production occurred from a small area of the No. 6 Vein within the Central Zone. Exploration work in 2018 has substantially expanded the number of the Central Zone vein exposures, and understanding thereof, resulting in the identification of high-quality targets for drill testing. Importantly, this year’s program has demonstrated that the historically productive No. 6 Vein is part of a much larger system of vein structures than had been previously recognized, now termed the No. 6 Vein Corridor. At least 20 major north-northeast-trending vein structures have been identified in the Central Zone along with northeast-trending stockwork zones in what is now interpreted to be a >1 kilometer-long by 250-metre-wide mineralized corridor that remains open to expansion at both ends (see Figure 1 inset).
The northeast-trending No. 6 Vein Corridor consists of widespread, near-vertical, high-grade silver-bearing massive sulfide veins. Very high combined silver and gold grades occur where these veins intersect with the numerous NNE trending gold and copper enriched veins. To date, 35 samples in the Central Zone have exceeded 1,000 g/t silver equivalent (“Ag Eq”) values, demonstrating the potential for high-grade mineralization in these vein systems (see Table 2 values from 2018 sampling). In addition, as part of the exploration program in 2018, a portable excavator was used to trench across key vein intersections to allow for detailed mapping of the structures, including their orientations and true thickness, and to better understand their relationships with the underlying geology (see Figure 2). Sample results from the trenches that indicate these features, returned composite mineralized widths of up to 16 m of 321 g/t Ag Eq and 7.3 m at 542 g/t Ag Eq with both trenches internal to the mineralized boundary, suggesting the potential for significantly broader packages of bulk tonnage mineralization. The small size of the equipment and topographic limitations did not allow for longer trenches to test across the entire 250 m wide mineralized zone in 2018, but such sampling will be a priority in future programs.
Bella and other Surrounding Target Areas
In addition to the work on the Central Zone, exploration on the surrounding areas included the West McKay, Bella, Falls, Red, Independence, Snowdrift, Nash and White Hill targets. Work in these target areas focused on systematic soil grid sampling, along with rock sampling within the identified zones of interest. Results of the 2018 field program have revealed more than a dozen newly discovered vein structures in new areas for follow with seven rock samples returning greater than 500 g/t Ag equivalent values.
Analytical metal values from the 2018 assays provide encouraging results and select assays from all surface related sampling activities at the McKay Hill Project are presented in Table 2. Select sample results from these veins, highlighted in grey, show elevated silver, gold, copper, lead and zinc numbers. These veins returned promising results for initial sampling efforts on new discoveries.

While compilation and analysis of the new results is ongoing, the Company envisions the following next steps for the McKay Hill Project:
- Continued reconnaissance and prospecting of the broader project area including the 42 new claims staked in 2018;
- Continued mapping, soil sampling and trenching activities to extend the six identified target areas as well as to expand covered with new soil grids over additional targets and extensions of current open anomalies; and
- Refinement of targets on the Central Zone mineralization for initial drill testing focused on the No. 6 Vein Corridor to assess the composite grades over the length and width of the kilometric scale corridor.

About the McKay Hill Project
The 100% owned McKay Hill Project covers 44 km2 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, approximately 50 kilometers to the south. McKay Hill is a historic high-grade producer that shows potential to host a significant district scale vein system like Keno Hill, with at least 37 identified mineralized vein structures that have seen very limited modern exploration. Recent field work conducted by Metallic Minerals has confirmed high grades of silver, lead and zinc as well as significant associated gold and copper values. Targets include both high-grade structurally controlled mineralization as well as potential bulk tonnage mineralization.
All 2018 rock and soil samples collected on the property were processed at Bureau Veritas Mineral Laboratories in Vancouver British Columbia.

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.
