Skeena Intersects 4.11 g/t AuEq over 22.08 metres at Eskay Creek

VANCOUVER, BC / ACCESSWIRE / April 23, 2020 / Skeena Resources Limited (TSXV:SKE)(OTCQX:SKREF) ("Skeena" or the "Company") is pleased to announce gold-silver drill results from the Company's 2020 Phase I surface drilling program at the Eskay Creek Project ("Eskay Creek") located in the Golden Triangle of British Columbia. Four ground-based surface drill rigs were utilized for the 2020 Phase I program in the 21B and 21C Zones to infill and upgrade areas of Inferred resources to the Indicated classification. Reference images are presented at the end of this release as well as on the Company's website.

Phase I Eskay Creek Drilling Highlights:

• 3.62 g/t Au, 41 g/t Ag (4.11 g/t AuEq) over 22.08 m (SK-20-259) - 21B Zone
• 2.61 g/t Au, 10 g/t Ag (2.74 g/t AuEq) over 36.19 m (SK-20-263) - 21B Zone
• 3.91 g/t Au, 21 g/t Ag (4.18 g/t AuEq) over 19.60 m (SK-20-264) - 21B Zone
• 4.61 g/t Au, 203 g/t Ag (7.32 g/t AuEq) over 8.43 m (SK-20-248) - 21C Zone

Gold Equivalent (AuEq) calculated via the formula: Au (g/t) + [Ag (g/t) / 75]. Reported core lengths represent 80-100% of true widths and are supported by well-defined mineralization geometries derived from historical drilling. Grade capping of individual assays has not been applied to the Au and Ag assays informing the length weighted AuEq composites. Processing recoveries have not been applied to the AuEq calculation and are disclosed at 100%. Samples below detection limit are nulled to a value of zero.

2020 Drilling Demonstrates Continuity in 21B Zone

The 2020 Phase I infill program at Eskay Creek continues to demonstrate the excellent continuity of the current resource model which is derived largely from historical drilling. Phase I infill drilling within the 21B and 21C Zones, which are situated in the deeper portions and later phases of the planned open-pit mining sequence, have correlated extremely well with the historical drilling with respect to grades, widths and spatial distribution.

In the 21B Zone, historical drill hole C97853 (1997) positioned nearest to the current Phase I drilling intersected 3.07 g/t AuEq over 18.26 metres in rhyolite breccias and minor mudstones. This intercept is separated by a horizontal strike distance of 20 metres to the north, and the lithologies and grades are similar to those observed in 2020 infill drill holes with intercepts of 3.62 g/t Au, 41 g/t Ag (4.11 g/t AuEq) over 22.08 metres (SK-20-259) and 3.91 g/t Au, 21 g/t Ag (4.18 g/t AuEq) over 19.60 metres (SK-20-264). Additional thicknesses of mineralization were also intersected in SK-20-263 which averaged 2.61 g/t Au, 10 g/t Ag (2.74 g/t AuEq) over 36.19 metres. Precious metal mineralization hosted in this portion of the 21B Zone is largely associated with sericite altered rhyolite breccias and flows.

A total of 4,327 metres has been drilled at Eskay Creek during the 2020 Phase I drill program so far. Additional results will be released shortly.

About Skeena

Skeena Resources Limited is a junior Canadian mining exploration company focused on developing prospective precious metal properties in the Golden Triangle of northwest British Columbia, Canada. The Company's primary activities are the exploration and development of the past-producing Eskay Creek mine, which contains a combined Indicated and Inferred 4Moz, 4.4 g/t gold-equivalent open-pit resource. The Company recently completed a Preliminary Economic Assessment (PEA) on Eskay Creek which highlights an after-tax NPV5% of C$638M, 51% IRR and a 1.2-year payback. Skeena is also exploring the past-producing Snip gold mine.

Qualified Persons

Exploration activities at the Eskay Creek Project are administered on-site by the Company's Exploration Managers, Colin Russell, P.Geo. and Adrian Newton, P.Geo. In accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects, Paul Geddes, P.Geo. Vice President Exploration and Resource Development, is the Qualified Person for the Company and has prepared, validated and approved the technical and scientific content of this news release. The Company strictly adheres to CIM Best Practices Guidelines in conducting, documenting, and reporting its exploration activities on its exploration projects.

Quality Assurance - Quality Control

Once received from the drill and processed, all drill core samples are sawn in half, labeled and bagged. The remaining drill core is subsequently securely stored on site. Numbered security tags are applied to lab shipments for chain of custody requirements. The Company inserts quality control (QC) samples at regular intervals in the sample stream, including blanks and reference materials with all sample shipments to monitor laboratory performance. The QAQC program was designed and approved by Lynda Bloom, P.Geo. of Analytical Solutions Ltd., and is overseen by the Company's Qualified Person, Paul Geddes, P.Geo, Vice President Exploration and Resource Development.

Drill core samples are submitted to ALS Geochemistry's analytical facility in North Vancouver, British Columbia for preparation and analysis. The ALS facility is accredited to the ISO/IEC 17025 standard for gold assays and all analytical methods include quality control materials at set frequencies with established data acceptance criteria. The entire sample is crushed and 1kg is pulverized. Analysis for gold is by 50g fire assay fusion with atomic absorption (AAS) finish with a lower limit of 0.01 ppm and upper limit of 100 ppm. Samples with gold assays greater than 100ppm are re-analyzed using a 50g fire assay fusion with gravimetric finish. Analysis for silver is by 50g fire assay fusion with gravimetric finish with a lower limit of 5ppm and upper limit of 10,000ppm. Samples with silver assays greater than 10,000ppm are re-analyzed using a gravimetric silver concentrate method. A selected number of samples are also analyzed using a 48 multi-elemental geochemical package by a 4-acid digestion, followed by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) and Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) and also for mercury using an aqua regia digest with Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) finish. Samples with sulfur reporting greater than 10% from the multi-element analysis are re-analyzed for total sulfur by Leco furnace and infrared spectroscopy.
