Eskay Mining Defines Multiple Mineralized Horizons Across Its 100% Owned Consolidated Eskay Precious Metal-Rich VMS Project

TORONTO, April 13, 2021 - Eskay Mining Corp. ("Eskay" or the "Company") (TSXV:ESK)(OTCQB:ESKYF)(Frankfurt:KN7) (WKN:A0YDPM) is pleased to announce that it has reviewed all data from its2020 exploration campaign and has conclusively identified multiple mineralized horizons at its 100% owned Consolidated Eskay precious metal-rich volcanogenic massive sulphide ("VMS") project in the Golden Triangle, British Columbia. This newly synthesized model of the sea floor mineralizing system demonstrates that at least six stratigraphic units are prospective for precious metal-rich VMS deposits across Eskay's 526 sq km property. Discussion about this new model will be presented by Dr. John DeDecker, VP Exploration at the Toronto Geological Discussion Group at 4PM Eastern Time, April 13,2021 (https://www.tgdg.net/event-4243258).

Summary:

• Systematic and rigorous geological investigations have been conducted since completion of the Company's successful 2020 field season. A new synthesis of the understanding of the sea floor mineralizing system demonstrates that multiple mineralized units are prospective for precious metal-rich VMS deposits across Eskay's 526 sq km property.
• On Eskay Mining's land tenure, six mineralized horizons have now been confirmed within the entirety of the Hazelton Group stratigraphy, the volcanic and sedimentary sequence of host rocks that formed on the sea floor (Figure 1). These include from top to bottom: 1) the Contact Mudstone horizon, host to the high grade Eskay Creek deposit, 2) the Eskay Rhyolite Mudstone Horizon, 3) the Bruce Glacier Mudstone Horizon, 4) The Spatsizi Mineralized Zone, 5) the Brucejack Lake Mineralized Zone, and 6) the Johnny Mt Dacite Mineralized Zone. Horizons 1-3 have been identified at the adjacent Eskay Creek property and continue onto the Company's property. Horizons 4-6 have been newly identified by Eskay and collectively represent a previously unrecognized VMS mineralizing event on the Company's land holdings and within in the Golden Triangle as a whole.
• The Johnny Mt Dacite Mineralized Zone, and the Brucejack Lake Mineralized Zone are within the Betty Creek Formation and are closely associated with mudstone, and dacitic and basaltic breccia. These rocks formed in a submarine environment and display a bimodal volcanic composition, a hallmark of back-arc rifting. Precious metal-rich sulfide mineralization hosted by these units is interpreted to be sub-seafloor replacement-style (Figure 2) and formed when mineralizing fluids percolated through and precipitated metals within dacite and basalt breccia piles in a shallow seafloor environment.
