Metallic Minerals Drills Bonanza Grade of 2,851 g/t Silver Equivalent at Caribou Target on the Keno Silver Project in the Yukon Territory

VANCOUVER, British Columbia, Dec. 13, 2017 (GLOBE NEWSWIRE) -- Metallic Minerals Corp. (TSX-V:MMG) (US OTC:MMNGF) (“Metallic Minerals” or the “Company”) is pleased to announce diamond drill results from seven holes drilled on the Caribou and Duncan targets in the Keno Summit area at its 100% owned Keno Silver Project in Canada’s Yukon Territory. A total of 1,320 meters of diamond drill core was collected from 14 holes in 2017 on areas prioritized during initial exploration work, namely Caribou, Duncan and two vein targets at Homestake (see Figures 1 and 2). The results clearly show that the Caribou target is a classic Keno-type high-grade system with bonanza grades, such as hole CH017-023, which intercepted 1.6 meters grading 2,851 g/t silver equivalent (1,405 Ag g/t, 26% Pb, 3.7% Zinc and 0.28 g/t Au), and that the system is open to further expansion down dip to the north and south. Final results from 2017, including the drilling from two priority targets on the Homestake block, are anticipated in the coming weeks.

The objective at the Caribou and Duncan targets was to drill below the shallow historic mining and sampling on the structure to determine the potential of the systems to host significant high-grade silver-lead-zinc deposits and to provide vectors to assist follow-up exploration. The Company completed six drill holes that intersected the Caribou structure, with highlight assay results shown below in Table 1. One hole was drilled at the Duncan target that intersected three mineralized structural zones within Keno Hill quartzite, one of the district’s preferred host rocks, down dip from the historic mine confirming the presence of the main structural corridor. Both areas are expected to priority targets for the planned 2018 exploration program.

Silver Equivalent (Ag Eq g/t) values assume Ag $16/oz, Pb $1.10/lb, Zn $1.25/lb, Au $1,250/oz, and 100% recovery.

Greg Johnson, Metallic Minerals Chairman & CEO stated, “We are very pleased with the first drill results from the Keno Silver Project, which support our strategy of systematic exploration to rapidly advance targets to drill stage and potential resource delineation. At the Caribou target, our results confirm the existence of high-grade silver and that we have a well-mineralized structure that is open to depth, with widths of 1-3 meters that are typical of the Keno Hill silver district. We now have 14 intercepts grading more than 800 g/t silver equivalent on the Caribou structure with the system open to expansion to the north and south (see Figure 3 - Caribou Long Section below). To put this in context the average reserve grade for primary silver deposits in the industry is 300 g/t silver or 500 g/t silver equivalent¹ with the average resource grade in the Keno district at 400-500 g/t silver. Future work at the Caribou target will focus on step out drilling of the higher-grade zones to determine the ultimate scale of the mineralized system. We anticipate conducting a robust 2018 exploration program and to continue development of the 12 priority targets, along with several new priority targets that were added through acquisitions in the district this year.”

Caribou Target Area

The Caribou target, located on the east side of Caribou Hill, was discovered and worked in the 1920s and 30s and produced 87 tons of high-grade material grading 6,072 g/t silver produced from the collective workings. A limited amount of shallow drilling and surface trenching was previously completed on the prospect between 2008 and 2011 with significant high-grade results reported (see Table 2 and 4 below).

Exploration by Metallic Minerals on the Caribou target in 2017 followed up on the historic surface work with detailed stratigraphic mapping, magnetic and VLF geophysical surveys, as well as the extension of soil sample grids over the broad target area. Diamond drilling was focused on testing down dip, along the structure below the shallow historic sampling, to determine the potential depth extension of the open-ended mineralization. The results of the drilling show a shallow dipping, well mineralized structure hosted in Keno Hill Quartzite, which hosts the majority of historic production and resources in the Keno Hill silver district (See Table 3 and Figure 3 below).

The drilling further shows that the Caribou structure is open to expansion and there remains significant exploration upside with the potential to develop a resource on this target (see long section in Figure 3 below). Drill holes are shown, with their respective grades, where they pierce the plane of the vein. Planned work for 2018 would include a continuation of step-out drilling of the shallow-dipping vein along the best mineralized shoots to the north and to the south where the high-grade mineralization remains open.

Duncan Target Area

The second area targeted with drilling in the Keno Summit area was an initial test of the structure at the historic Duncan mine, which had the highest recorded grade of production in the Keno Hill silver district at 25,518 g/t silver from the shallow workings². The Duncan vein was staked in 1919 and saw limited development work in 1920s. The vein is exposed on the steep north face above Silver Basin, which has seen only limited exploration including minor hand trenching and a few bulldozer cuts since the 1920s. Metallic Minerals completed the first known drill hole on the target from the plateau south of the prospect. This down dip test confirmed the presence of a broad window of prospective quartzite and intersected three anomalously mineralized structural zones within the Keno Hill quartzite ending in 70 g/t silver equivalent material. Drilling difficulties limited the further continuation of the hole, falling short of testing the full quartzite package. However, these results confirm the presence of the Duncan target structure, which may have up to 200 vertical meters of Keno Hill Quartzite host rock positioned down dip from the high-grade Duncan shaft, with open-ended strike potential. Follow up drilling in 2018 will be designed to test the full depth potential of this highly-prospective target.

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.
