Metallic Minerals Provides Exploration Update on Central Keno Hill Targets including Identification of Two New Multi-Kilometer Soil Anomalies at the Keno Silver Project
VANCOUVER, British Columbia, Aug. 14, 2019 (GLOBE NEWSWIRE) -- Metallic Minerals Corp. (TSX-V: MMG; US OTC: MMNGF) (“Metallic Minerals” or the “Company”) is pleased to provide the second of a series of news releases covering its Keno Silver Project, directly adjoining Alexco Resource Corp’s (“Alexco”) operations, in the Yukon Territory of Canada. These results reflect work conducted to date on the central 12 km of the 35 km-long Keno Hill Silver District (see Figure 1), with results from Keno East having been previously announced.
The Keno Hill Silver District is recognized as one of the world’s highest-grade producers of silver with over 300 million ounces of past production and current Measured and Indicated resources1,2. The district remains highly-prospective, as demonstrated by the number of recent major discoveries and the grade and scale of those deposits.
Results of on-going compilation and synthesis of historic exploration data, along with results from exploration to date in the Central Keno Hill Silver District, have confirmed:
- Bonanza-grade Keno-style silver mineralization including samples of over 1,000 g/t silver at the Caribou and Homestake advanced-stage targets with eight additional earlier stage targets that have not yet been drill tested;
- The new interpretation of a structural corridor at the Keno Summit area that encompasses the Keno Hill mine, Gold Hill, Duncan and Caribou structures and that is comparable in size and style to the Bermingham-Calumet system (see Figure 3) in the more extensively explored Galena Hill area in the West Keno Hill Silver District;
- The interpretation of additional parallel structural corridors to the north and south that host the Bounty and Homestake targets that are similar to those in the more explored parts of the district; and
- The identification of two new multi-kilometer soil targets with highly elevated silver, lead, and zinc in soils in the Keno Summit area that extend from areas with recognized high-grade Keno-type high-grade structures.

The central part of the Keno Hill Silver District was one of the original areas of historic discovery and, though less developed than the western part of the district, the area hosts over 100 million ounces of past production and current resources in shallow deposits that have not been systematically explored to depth or along strike. The Central Keno District includes the historic producing Keno Hill, Lucky Queen and Sadie Ladue mines along with six smaller high-grade historic mines on Metallic Minerals land holdings within the Keno Summit target area.
Greg Johnson, President and CEO, commented, “Over the past several months, the Company has been developing and refining its 3D geologic and structural model for the Central Keno Hill Silver District and has completed new processing and interpretation of airborne resistivity and magnetic data, including integration of new remote sensing data over this part of the project. A key indication from this work is that the advanced Caribou, Duncan, and Gold Hill drill targets form part of a much larger structural corridor that includes the historic Keno Hill mine and that is comparable in surface expression and structural setting to the +100 million-ounce Bermingham-Calumet system (see Figure 3) in the more extensively explored Galena Hill area in the West Keno Hill Silver District. In addition, parallel structures with similar structural characteristics occur both to the north and south at the Bounty and Homestake target areas (see Figure 3).
“The Central Keno District shows excellent potential for the continued expansion of areas of known silver mineralization and for new discoveries from our surface exploration work and reconnaissance drilling. This will be an important priority area of focus and follow-up work for exploration in 2019. Drilling of surface targets at the Keno Summit target area has successfully intercepted the targeted mineralized structures at over a 90% success rate. Our focus now is to vector along these mineralized structures within the preferred host rock windows to define the areas of thicker, high-grade Keno-style silver mineralization that can build towards significant mineral resources. We are excited about the second half of the year as we follow up on a number of important recent developments and value creating initiatives. We look forward to providing additional news, including new results from 2019 exploration along with an update on the modelling and plans at the Company’s targets in the West Keno Hill Silver District.”

Keno Summit Target Area
As one of the most advanced parts of Metallic Minerals’ Keno Silver Project, the Keno Summit area has been an important focus of the Company’s directed exploration programs over the last two field seasons, along with the parallel Homestake target area. The Keno Summit area contains numerous advanced-stage targets (Caribou, Duncan, Gold Hill), drill-ready targets (Silver Basin, Vanguard, and Bounty), as well as highly prospective significant early-stage prospects (Faith, Avenue, Beauvette, Vancouver, and Isabel) that are planned to be a focus for continued systematic exploration.
Recent work by Alexco has significantly advanced the geologic understanding of the structural controls to mineralization in the Keno Hill Silver District. Metallic Minerals has been applying this structural framework to the less explored parts of the District, recognizing the similarities in the structural controls and orientations within the largest historic producers and current resources. Assessing these structural orientations along with the potential structural windows in the key host rocks is an important factor in exploration on the advanced-stage targets and assists in prioritizing among the early-stage target areas.

Exploration across the entire Central Keno District has included 98 shallow reconnaissance diamond core holes and 61 prospecting RAB holes. The average grade of the 34 highlighted intervals in tables 1 and 2 below is 1,036 g/t AgEq, or 519 g/t Ag, 7.88% Pb, 1.65% Zn, and 0.71 g/t Au. A total of 543 surface rock samples have been collected from trenches, outcrops, and rubble crop material with over 92 samples returning grades over 1,000 g/t AgEq.
The following sections summarize the most significant targets in the Central Keno Hill Silver District along with results to date and exploration plans for 2019.

Caribou Target
The Caribou target area is one of the most advanced individual targets at the Keno Silver Project and is located at the eastern side of the Keno Summit area. The Caribou vein historically produced 87 tonnes of high-grade material grading 6,072 g/t silver from near surface and is interpreted to be a significant connecting structure between the main shear structures in the Keno Summit structural corridor (see Figure 3 and 4). Trenching and diamond drilling on the Caribou target have confirmed the presence of Keno-type silver-lead-zinc mineralization, including bonanza grades highlighted by CH017-023 with 1.6 meters grading 2,851 g/t AgEq (1,405 Ag g/t, 26% Pb, 3.7% Zn, and 0.28 g/t Au) and Hole CH18-30 which intersected a 2.75 m structure including 0.55 meters grading 2,918 g/t AgEq (1,768 Ag g/t, 21% Pb, 2.26% Zn and 0.36 g/t Au) (see Table 1 and 2 for complete listing of significant intervals). Drilling at Caribou has been successful in systematically intercepting the shallow mineralized structure and future exploration will focus on step out drilling from the areas of known mineralization to continue to grow the area of drill defined mineralization (see Figure 5).
The results to date at the Caribou target show:
- The main Caribou vein structure has been drill tested along approximately 350 m of strike length and 100 meter down-dip extent within a host quartzite package that is estimated to be 500m wide x 700m depth and which is open to the south;
- Drilling, primarily from 2017 and 2018, has consistently pierced the Caribou structure with 22 significant intercepts at true widths between 0.5 meters up to 4 meters with significant grades ranging from 200 g/t AgEq to over 4,000 g/t AgEq (see Table 1 and 2);
- With only relatively shallow drilling conducted to date, the potential for en echelon or parallel vein structures to the main Caribou structure have not yet been tested, nor have intersections with the main Y or P structures that define the broader structural corridor; and
- A newly identified 2 km by 1 km soil anomaly of over 10 g/t AgEq continues directly south of Caribou and supports the potential for significant extension of mineralization related to the Caribou vein system southward.
Down slope to the south of the exposed Caribou vein lies a largely untested area of Keno Hill quartzite where several significant vein intersections may occur. Veins trending into the area include the Caribou vein’s southern projected extension, along with the Devon, Divide, Avenue, Bema and the historically producing Faith vein structure. This target area contains limited outcrop that has not been drilled and is further supported by soil sampling that identified a 2 km x 1 km soil anomaly of over 10 g/t AgEq over the area that remains open to expansion. Rock sampling from surface exposures of the Faith structures returned up to 9,303 g/t AgEq (5,829 g/t Ag, 61.8% Pb, 7.2% Zn, and 1.9 g/t Au), 7,449 g/t AgEq (3,713 g/t Ag, 77.2% Pb, 0.7% Zn and 0.34 g/t Au) and 6,733 g/t AgEq (4,712 g/t Ag, 34.1% Pb, 5.7% Zn, and 1.13 g/t Au).
Exploration at Caribou is planned to continue to focus on extensions to the south including the newly identified soil anomaly, as well as to test the potential for parallel or en echelon structures and the intersections with the main Y and P controlling structures within the broader structural corridor.

Duncan Target
The Duncan target lies west of Caribou and represents another important structural target window in the Keno Summit area. The historic Duncan mine had the highest recorded production grade in the Keno Hill Silver District at 25,518 g/t silver from shallow workings. Rock sampling from surface exposures of the mineralized structures returned up to 7,649 g/t AgEq (3,713 g/t Ag, 77.6% Pb, 0.1% Zn and 0.46 g/t Au) and 6,157 g/t AgEq (3,963 g/t Ag, 44% Pb, 0.6% Zn and 0.77 g/t Au). Metallic Minerals completed the first known reconnaissance drill hole on the target from the plateau south of the prospect in 2017. This down-dip test (CH17-18) confirmed the presence of a broad window of prospective quartzite and intersected a significant segmented vein-fault structure over 22.0 m with strands composed of 3.9 m, 3.3 m and 1.3 m and ending in 70 g/t silver equivalent material. Mechanical drilling difficulties limited the further continuation of the hole, falling short of testing the full width of the identified structure. However, these results confirm the presence of the Duncan target structure, which has a potential +500 m thick window within the host Keno Hill quartzite, providing the opportunity for a Keno-type silver deposit of significant scale. Future exploration is planned to target this structural window below the area of high-grade historic production.
Gold Hill Target
The Gold Hill target area lies between the Duncan and Caribou targets to the east and the historic Keno Hill mine to the west and is interpreted to be a northeast-trending, connecting fault structure between the main shears along the Keno Summit structural corridor. Reconnaissance drilling in 2018 at Gold Hill targeted a high-grade silver, lead, zinc bearing structure that was discovered by trenching in 2017. Results from the trenching included 3.1 m at 1,023 g/t AgEq and 0.21 m at 3,526 g/t AgEq in channel samples. Four reconnaissance drill holes intersected the vein/fault structure and returned anomalous Keno-type silver-lead-zinc mineralization with GH18-003 intercepting 1.8 m grading 303 g/t AgEq (105 Ag g/t, 3.26% Pb and 0.98% Zn). These positive results at Gold Hill confirm the presence and orientation of the structure within a significant structural window that is interpreted to be over 400 m wide by 600 m deep in competent quartzite. Future exploration is planned to focus on step-out drilling along the identified mineralized structure to test for areas of increased thickness and higher-grade material within the Gold Hill structural window.
Bounty, Silver Basin and Vanguard Targets
Additional work in the Keno Summit target area, based on ongoing historic data compilation combined with prospecting, mapping and soil sampling over the last two years, has identified several target areas for first phase drill testing. The geology of the Bounty, Silver Basin and Vanguard targets demonstrates the characteristics for a Keno-type deposit including the structural setting and key host rocks. Surface vein exposures on each of the target areas have returned significant grades with work focused on refining targets for first phase drill testing. In addition, soil sampling during the 2017 and 2018 field programs has outlined significant anomalies at each of the above target areas at the Keno Summit (Figures 5 and 6).
The Bounty target is located east of the Lucky Queen Mine trend (11 Moz Ag) near a contact of basal quartzite and greenstone along a parallel structural corridor to the north of the Keno Hill mine. Surface exposures and trenching at the Bounty target have yielded grades of up to 15,795 g/t AgEq (12,078 g/t Ag, 71.1% Pb, 1% Zn and 1.33 g/t Au) and 6,711 g/t AgEq (3998 g/t Ag, 39.3% Pb, 14.6% Zn and 0.33 g/ Au). The surface expression of the structure has been identified for over 300 m on strike. This area is a priority target for target refinement and first phase drilling.
Also parallel with the main Keno Summit vein/structure corridor, the Silver Basin target area was the site of historic high-grade, near surface production. Surface sampling has highlighted multiple veins in the Silver Basin vein/fault complex with rock chip sample grading up to 10,668 g/t AgEq (7,063 g/t Ag, 73.5% Pb, 0.3% Zn and 0.8 g/t Au) and 6,206 g/t AgEq (2,956 g/t Ag, 68.1% Pb, 0.2% Zn, and 0.29 g/t Au). This area will be a priority target for target refinement and first phase drilling.
The Vanguard vein target falls within the structural corridor between the Bellekeno mine and Keno Hill mine and was the site of very high-grade historic production. Soil sampling has confirmed the surface expression of this high-grade structural system and follow up work will focus on refining targets for first phase drilling.
Vancouver, Isabel, and Diamond Targets
Exploration at the early stage Vancouver, Isabel and Diamond targets has focused on mapping and soil sampling which has identified several highly prospective targets for further follow up work in preparation for first phase drilling. The Vancouver target lies on trend with an offset portion of the high-grade Lucky Queen structure, which historically produced over 11 Moz of silver. The Diamond target, which lies along the trends of several important structures at the Keno Summit, was identified by strong soil geochemistry. Lastly, the Isabel target has a strong multi-gram silver in soil anomaly covering over 400 m that remains open to expansion and is on trend with the historic producing Shamrock and Gambler deposits that averaged over 5,000 g/t Ag1. Though earlier stage each of these targets represent significant potential for discovery with further systematic exploration.
Homestake Target
The historically productive Homestake vein corridor is located south of the Keno Summit Target Area along a parallel structural corridor. The Homestake target area is comprised of two parallel vein structures within a broad structural corridor over 200 m wide that has a demonstrated strike length of over 1 km in the host Keno Hill quartzite. Homestake #1 vein shows classic Keno-style, high-grade silver-lead-zinc mineralization, while the #2 vein can also show significantly elevated gold with modest silver grades, which is characteristic of some structures in the larger deposits within the Keno Hill Silver District. The strongest grades to date include assays of 4,027 g/t silver from drilling and 4,717 g/t silver from trenching on the Homestake #1 vein, and 22.1 g/t gold with 332 g/t silver from trenching on the Homestake #2 vein (see Tables 3 Drilling and Table 4 Trench results).
Over the larger Homestake area there is limited bedrock exposure, but soil sampling has identified a broad corridor of elevated Ag-Pb-Zn results that strikes over 4 km within the host Keno Hill quartzite (Figure 6, below). The orientation and general indications are that this structure is comparable to the structure corridors seen at the Keno Summit and Bermingham/Hector-Calumet.
Historic drilling was targeted near the Homestake adit area where the vein is exposed at surface and early stage sampling and trenching work returned high grades. Drilling at Homestake over the last two seasons has targeted both extensions of higher-grade intervals in this area and the projected intersection of the Homestake #1 and #2 veins 250 m northeast of their previously suggested extent. To date there are 21 drilled vein intersections grading more than 600 g/t silver equivalent on the Homestake structures, including five that exceed 10 g/t gold on the Homestake #2 structure. Limited drilling in 2018 intercepted the mineralized #2 structure along strike in all 3 shallow holes drill holes returning from 21 g/t AgEq to 232 g/t AgEq. The intercepted structures showed significant widening of the structures to 5.6 and 24 meters respectively within a thickening quartzite package. Exploration at Homestake will continue to focus on extensions of the structures to the southwest and northeast along the newly identified soil anomalies with a focus on targeting thicker, more massive sections of the Keno Hill Quartzite stratigraphy within the estimated 1 km thick target window.

Next Steps on Central Keno
The Company is very encouraged with the results from its Keno Silver Project to date and specifically from the Central Keno Silver District reported above where multiple targets at different exploration stages present compelling opportunities for new discoveries and rapidly building on known mineralization towards developing new mineral resources.
Results of on-going compilation and synthesis of historic exploration data, along with results from exploration to date in the Central Keno Hill Silver District, have confirmed the presence of high-grade Keno-style silver mineralization at the Caribou and Homestake advanced-stage targets and have identified eight additional earlier stage targets that have not yet been drill tested. This combined with the new recognition of structural corridors at the Keno Summit area that are comparable in surface expression and style of the +100 million-ounce Bermingham-Calumet system suggests the opportunity to develop Keno-type silver deposits in this underexplored historic producing part of the Keno Hill silver district. The identification to two new multi-kilometer soil targets in the Central Keno Silver District with highly elevated silver, lead, and zinc in soils that extend from areas with known Keno-style mineralization supports the potential for significant expansion of the these known targets at the Keno Summit target area. These new soil targets are in addition to the previously announced eight multi-kilometer soil anomalies in the East Keno Silver district that are also associated high-grade Keno-type vein structures in an area that is untested by drilling.
Exploration continues at the Keno Silver Project with a two part focus of continued exploration on the advanced stage targets which have drill defined high-grade Keno-style mineralization, in parallel with further target refinement work in preparation for drill testing on the new East Keno targets. We look forward to providing additional updates on plans and targets in the West Keno area and updates from exploration on the Keno Silver Project as the program unfolds during the 2019 exploration season.

Quality Assurance / Quality Control
All samples were assayed by 36 Element Aqua Regia Digestion ICP-MS methods at Bureau Veritas labs in Vancouver. 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.
