VANCOUVER, BC / ACCESSWIRE / September 7, 2021 / Skeena Resources Limited (TSX:SKE)(OTCQX:SKREF) ("Skeena" or the "Company") is pleased to report that it has initiated a 35,000 metre regional and near mine exploration drilling program at the Eskay Creek gold-silver project ("Eskay" or the "Project") located in the Golden Triangle of British Columbia. One surface-based helicopter supported drill rig is currently active at the Project testing the strike extensions of the 22 Zone. Additional rigs will be added as they become available. Reference images are presented at the end of this release as well as on the Company's website.

Overview

When Eskay Creek was optioned in 2017 and ultimately purchased from Barrick in 2020, the Company's drilling programs almost wholly focused on de-risking the project through category conversion (infill) drilling. To date, very little grassroots exploration has been performed on the property by Skeena. The purpose of the 2021 exploration program is to perform focused and expedited regional and near mine exploration with the goal of adding greater than 1 million ounces of gold equivalent resources to enhance the existing Eskay Creek mine plan. Pragmatic exploration will focus on defining bodies of near surface, bulk tonnage Au-Ag mineralization to provide supplemental feed for the Company's current Prefeasibility Study level contemplated truck and shovel open-pit mine plan. Ranking will favour targets with spatial proximity to the proposed processing facilities.

Although considerable exploration potential exists for additional underground resources, these are not considered in this year's exploration directive due to higher costs per ounce for discovery and delineation and the Company's current focus on open-pit mineralization.

2021 Drill Targets

A total of 35,000 metres has been allocated for the 2021 regional exploration drilling program. Judicious target ranking matrices were developed to maximize the likelihood of enhancing the global project economics and these criteria were derived from the 2021 desktop studies and field-based programs. Overall, allocation of drill metres will be dynamic and results driven as new information becomes available from the 2021 program.

Primary targets include strike and depth extensions of the 22 Zone (refer to attached image) as well as rock and soil anomalies that occur along the main Eskay Trend from the 21A Zone south towards the 22 Zone and Tom MacKay Zones. Detailed targeting within these larger areas is further constrained by deposit specific geological, structural, geophysical, and geochemical considerations known to be critical for emplacement of Eskay Creek style mineralization. The southernmost mineralized occurrence of Contact Mudstone within the Eskay Rift occurs in the 21A Zone. As such, targets located south of this locale are dominantly searching for synvolcanic feeders as well as newly identified mineralization hosted by the Lower Mudstone and Even Lower Mudstone units. Historic drill testing of these target models outside of the currently defined resources is very sparse. Significantly, a two-kilometre-long trend of identified targets located a short distance to the south of the 21A Zone has no historic drill testing.

Secondary targets include the Eskay Porphyry, which has received only limited historical drilling and was never analyzed for gold, as well as favourably altered Lower Mudstone and dacite units located on the east limb of the Eskay Anticline. These lower stratigraphy target areas have never been drill tested and experienced only limited historic exploration activity through the early 1990's.

New Geophysical Datasets

The Company has collected high resolution airborne magnetic tensor gradiometry data across the entire property as well as a detailed three-dimensional DCIP survey over the axis of the Eskay Creek anticline from the Bowser Basin south to the Tom MacKay Zones. The incorporation of these datasets into the larger litho-structural model has allowed for an understanding of the geophysical responses of the known Eskay Creek mineralization and has illuminated the electrical and magnetic responses of Eskay style mineralization that can be applied to other regional targets.

2021 Soils Program

To date, the inherited soils data collected by previous operators has demonstrated strong correlations between proven Au-Ag mineralization exposed at surface and B-Horizon Au soil anomalies. Examples include the 22 Zone, 21A Zone, HW and Tom MacKay Zones. As such, the utilization of soil programs has proven effective in determining the locations and potentially areal extents of mineralized bodies exposed at surface. Historical soils coverage was discontinuous across the property, particularly along the Eastern Limb of the Eskay Anticline. Further to this, data collected prior to Skeena's ownership is poorly documented, generally lacks any quality assurance/quality control checks and is therefore of dubious quality. The 2021 exploration program will be supported by a recently completed soil survey which essentially covers the entire property apart from areas defined as Bowser Basin. The program entailed 116 line kilometres on 100 metre line spacings with 25 metre sample intervals. Given the

surficial footprint criteria for a near surface bulk tonnage target, these soil grid parameters permitted adequate coverage to detect an economic target without unnecessary detail or cost.

2021 Mapping Program

In parallel with the soil program, a regional mapping and lithogeochemical sampling program was conducted over selected areas of the property with the secondary goal of populating a database of rock samples for lithogeochemical characterization. The mapping has assisted in developing a broader litho-structural understanding of the Eskay Rift, whilst the collection of in situ samples supported the litho-geochemical framework.

Eskay Creek Feasibility Study Update

Skeena is also pleased to report that it has awarded the Feasibility Study contract for Eskay Creek to Ausenco Engineering Canada Inc. ("Ausenco"), supported by SRK Consulting (Canada), and AGP Mining Consultants. The Feasibility Study is on track to be completed in Q1 2022.
