Eskay Mining Encounters 1.51 gpt Au and 25.39 gpt Ag over 43.1m and 2.84 gpt Au and 22.17 gpt Ag over 16.4m in Extensional Drilling at the TV Deposit, Consolidated Eskay Project, Golden Triangle, BC

TORONTO, ON / ACCESSWIRE / February 23, 2023 / Eskay Mining Corp. ("Eskay" or the "Company") (TSXV:ESK) (OTCQX:ESKYF) (Frankfurt:KN7)(WKN:A0YDPM) is pleased to announce further encouraging diamond drill results from its 2022 exploration program at its 100% controlled Consolidated Eskay Property in the Golden Triangle, British Columbia.

"Results from our 2022 exploration season demonstrate Eskay's team has made considerable progress toward unraveling the district-scale potential of VMS mineralization surrounding the Eskay Creek deposit," commented Dr. John DeDecker, VP of Exploration for Eskay Mining Corp. "Achievements of the 2022 exploration program include defining a new trend of VMS mineralization along the Scarlet-Tarn corridor parallel to and approximately seven kilometers east of the Eskay anticline. Tarn Lake and Scarlet Knob are situated along an east-west trending VMS feeder structure hosted by Eskay rhyolite like that seen in the footwall of the Eskay Creek deposit. Mapping and prospecting define a westward stratigraphic younging direction suggesting that stockwork and replacement-style mineralization at Tarn Lake may represent feeders to seafloor-hosted mineralization up-section towards the important Contact Mudstone horizon, host to high-grade mineralization at Eskay Creek. This recognition is a significant step towards meeting our goal of discovering new Eskay Creek-like high-grade VMS systems. Drilling at TV now shows that Au- and Ag-bearing massive sulfide extends 100 m along strike and overlies an even more extensive zone of stockwork mineralization. We are eager to follow up on all of these encouraging results in 2023."

TV Extensional Drilling

Highlight results:

• 4.61 gpt Au and 22.17 gpt Ag (4.89 gpt Au Eq) over 6.28m within 2.84 gpt Au and 22.17 gpt Ag (3.13 gpt Au Eq) over 16.36m in hole TV22-105
• 2.66 gpt Au and 30.45 gpt Ag (3.05 gpt Au Eq) over 10.56m within 1.51 gpt Au and 25.39 gpt Ag (1.83 gpt Au Eq) over 43.09m in hole TV22-120
• 3.36 gpt Au and 109.50 gpt Ag (4.76 gpt Au Eq) over 2.00m within 1.14 gpt Au and 30.40 gpt Ag (1.53 gpt Au Eq) over 30.56m in hole TV22-97
• 6.88 gpt Au and 21.00 gpt Ag (7.15 gpt Au Eq) over 1.10m within 1.28 gpt Au and 87.92 gpt Ag (2.41 gpt Au Eq) over 14.95m in hole TV22-109

Drilling at TV in 2022 expanded the footprint of both the Upper Massive Sulfide Zone and Stockwork Zone at TV (Figures 1, 2 and 3). Massive sulfide mineralization now extends approximately 100 m along strike, ranges from 5 to 10 m in thickness, and is characterized by sulfide lenses hosted by intensely silicified carbonaceous mudstone associated with peperitic dacite (Figures 4 and 5). Massive and semi-massive sulfide mineralization overlies an extensive stockwork feeder zone hosted by dacitic and andesitic breccia and peperite. Stockwork mineralization now extends approximately 175 m along strike, 175 m down dip, and ranges in thickness from 50 to 100 m. Significantly, drill holes testing the up-dip extent of the stockwork zone (TV22-106, 108, and 112) intercepted strongly anomalous Au and Ag values with interspersed values over 1 gpt Au equivalent. Rock chip samples collected from the vicinity of these drill holes suggest that this up-dip zone may contain higher grade pockets of Au and Ag mineralization (Figure 2).

Significant mineralized intervals from 2022 drill holes completed in the vicinity of the TV deposit are presented in the table below. A complete list of the coordinates of drill holes including holes without significant mineralized intercepts is found at the bottom of this release.

Au Eq and Ag Eq values have all been adjusted to the silver-to-gold ratio of 78:1 for this news release.

Tarn Lake

Assay results from the maiden drill program at Tarn Lake have already defined an 80m-long open-ended trend of Au mineralization that dips west-northwest (Figures. 1, 7 and 8). Rock chip sample results suggest that Au mineralization extends up-dip from the drill holes to the surface. Mineralization remains open down-dip.

Sulfide mineralization intercepted by drilling is dominantly replacement-style and stockwork-style (Figure 9), and is hosted by intensely altered Eskay rhyolite. This style of mineralization and intense hydrothermal alteration are consistent with a position in the immediate sub-seafloor environment of a VMS feeder zone. Geological mapping, drilling, and lithological facies analyses show extensive rhyolite-bearing volcaniclastic debris flow beds, peperitic rhyolite, and flow-banded rhyolite defining a rhyolite dome complex that formed at a paleoseafloor position proximal to a syn-volcanic VMS feeder structure, supporting the interpretation based on mineralization and alteration. Based on this geology, Eskay's exploration team thinks there is considerable potential for the presence of seafloor-hosted VMS mineralization at one or more horizons at Tarn Lake, as is seen along the parallel Eskay Creek-Sib-Lulu trend to the west (Figure 10).

Eskay's geological mapping team has determined that the stratigraphic younging direction along the Scarlet-Tarn trend is to the west, and that the contact between the Eskay rhyolite and the Willow Ridge basalt lies to the west of Tarn Lake (Figure 10). The contact between these lithologies defines the Contact mudstone horizon that hosts the world-class Au-Ag mineralization at Eskay Creek Mine. Given that recent rock chip sampling indicates Au mineralization continues west of Tarn Lake, it is possible the Tarn VMS system continues up-stratigraphy to the Contact mudstone horizon. These findings are a significant step towards our goal of finding Eskay Creek-like VMS deposits on the Consolidated Eskay Property.

In addition to the potential for Au and Ag mineralization down-dip and up-section from 2022 drilling, there is considerable potential for mineralization to extend beneath Bruce Glacier to Scarlet Knob along east-west trending feeder structures (Figure 11). These feeder structures are delineated by andesite dikes surrounded by sulfide mineralization and intense hydrothermal alteration of the host Eskay rhyolite.

Significant drill results from hole TN22-8 completed at Tarn Lake are presented in the table below.

Au Eq and Ag Eq values have all been adjusted to the silver-to-gold ratio of 78:1 for this news release.

2022 Exploration Program

The fundamental goal of the 2022 exploration program was to identify new precious metal-rich VMS deposits across the Consolidated Eskay Project through early-stage work including mapping and geochemical sampling, and more advanced work including widely spaced drilling. During the 2022 exploration season, Eskay Mining successfully completed 29,500m of diamond drilling along the TV-Jeff corridor and along the Scarlet Ridge-Tarn Lake trend.

Drill results discussed in this news release come from holes drilled in the vicinity of the TV deposit and the newly discovered Tarn Lake mineralizing system. As of this news release, all assays have returned from the 2022 drill program.

Au Eq and Ag Eq Calculations and True Width:

Note on use of Au eq (Au eq=Au+Ag/78) and Ag eq (Ag eq=Au*78+Ag): Mineralization at the TV and Jeff deposits displays similar characteristics and mineralogy to the Eskay Creek deposit and therefore for Au eq, and Au:Ag, a ratio of 78:1 is used and Au eq and Ag eq values are deemed to be reasonable based on assumed gold recovery (84.2%) and silver recovery (87.3%) as reported in the Eskay Creek Project NI 43-101 Technical Report and Prefeasibility Study, British Columbia, Canada, Effective Date: 22 July, 2021, Prepared for: Skeena Resources Ltd., Prepared by: Absence Engineering Canada Inc.

True widths of reported intercepts are not fully understood at this time but given the moderately dipping tabular nature of these deposits and the steep angle of drilling, Eskay geologists estimate true widths represent approximately 70-90% of the reported drill intercept lengths.
