Skeena Intersects 10.52 g/t Gold Over 4.10 Metres at Snip

Drill Results

Skeena Intersects 10.52 g/t Gold Over 4.10 Metres at Snip

Vancouver, BC ( August 9, 2018) Skeena Resources Limited (TSX.V: SKE, OTCQX: SKREF )

(“Skeena” or the “Company”) is pleased to report additional assay results for six drill holes from the

Phase II underground drilling program at the Company’s 100% owned Snip Gold Project (“Snip”)

located in the Golden Triangle of British Columbia.

The Phase II drilling program is now complete. A total of 9,583 metres was drilled over 48 underground

drill holes and two surface drill holes. Building upon the data gathered from the Phase I campaign, the

Phase II program was designed to expand newly modelled zones via widely spaced exploratory drill

step-outs, further delineate known mineralization in areas of low drilling density and validate the

historical data in preparation for a mai den resource estimate at Snip. A reference mine section is

presented at the end of this release, and on the Company’s website.

Phase II Drilling Highlights:

• 11.03 g/t Au over 3.00 m (UG18-101)

• 185.00 g/t Au over 0.60 m (UG18-101)

• 23.84 g/t Au over 1.50 m (UG18-103)

• 17.93 g/t Au over 2.00 m (UG18-103)

• 8.68 g/t Au over 3.90 m (UG18-103)

• 10.52 g/t Au over 4.10 m (UG18-104)

Eastern Twin Zone Continues to Demonstrate Continuity

Delineation drilling on the Eastern Twin Zone continues to add gold grade and confidence to areas

that were not fully sampled during previous operator s’ historical drilling programs. The Phase II

program is designed to populate this area with new drilling and analytical data in preparation for a

maiden resource estimate at Snip.

2018 Phase II drillhole UG18-104, which intersected 10.52 g/t Au over 4.10 metres in the Eastern

Twin Zone, is located 25 metres downdip of UG18 -102 which intersected 11.14 g/t Au over 2.00

metres. These new intersections are bracketed up and down dip by previously reported 2018 drillholes

UG18-093 and UG18-091 which intersected 9.14 g/t Au over 10.20 metres and 5.60 g/t over 19.85

metres respectively, for a total dip extent of 75 metres.

Additional mineralization surrounding the Eastern Twin Zone was also intersected by UG18-101 which

averaged 11.03 g/t Au over 3.00 metres in the footwall. UG18-101 also intersected 185.00 g/t Au

over 0.60 metres occurring 15 metres into the hangingwall to the Eastern Twin Zone, where a new

zone of mineralization is beginning to be defined.

Discussion of Historical Data and Practices

Regrettably, prior to the implementation of National Instrument 43- 101 standards, reclamation of the

mine in 1999 included disposal of all historical drill core, resulting in the inability to now validate any

prior operators’ databases to modern standards. This lack of historic drill core and supporting drilling

documentation, paired with the wide spacing of historical drilling in undeveloped areas necessitates

that Skeena devote a percentage of its drilling campaign to validate the historical data. This will allow

for high confidence underground resources to be reported.

About Skeena

Skeena Resources Limited is a junior Canadian mining exploration company focused on developing

prospective precious and base 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

Snip mine and the recently optioned Eskay Creek mine, both acquired from Barrick. In addition, the

Company has completed a Preliminary E conomic Assessment on the GJ copper -gold porphyry

project.

On behalf of the Board of Directors of Skeena Resources Limited,

Qualified Persons

Exploration activities at the Snip Gold 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, labelled 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 250 grams 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 10 ppm are re-analyzed

using a 1,000g screen metallic fire assay. A selected number of samples are also analyzed using a

48 multi -elemental geochemical package by a 4- acid digestion, follow ed by Inductively Coupled

Plasma Atomic Emission Spectroscopy (ICP -AES) and Inductively Coupled Plasma Mass

Spectroscopy (ICP-MS).
