Vancouver, BC (February 17, 2021) Skeena Resources Limited (TSX: SKE, OTCQX: SKREF) (“Skeena” or the “Company”) is pleased to report additional diamond drill core results from the Phase 2 campaign of definition and exploration drilling at the Eskay Creek Project (“Eskay Creek” or the “Project”) located in the Golden Triangle of British Columbia. The Phase 2 infill program, focused upon resource category conversions for the Pre-Feasibility Study (“PFS”) on open-pit constrained resources, is now complete. The Company has also recently completed a 5,000 m near-mine exploration program at Eskay Creek and is awaiting results. Reference images are presented at the end of this release as well as on the Company’s website.

Gold Equivalent (AuEq) calculated via the formula: Au (g/t) + [Ag (g/t) / 75]. True widths range from 70-100% of reported core lengths. Length weighted AuEq composites are constrained by geological considerations. Grade-capping of individual assays has not been applied to the Au and Ag assays informing the length-weighted AuEq composites. Metallurgical processing recoveries have not been applied to the AuEq calculation and are taken at 100%. Samples below detection limit were nulled to a value of zero.

New In-Pit Mineralization Discovered Above the 21C Zone
Situated within the open-pit contemplated by the Company’s 2019 Preliminary Economic Assessment, a previously unrecognized zone of mineralization has been discovered above the 21C Zone.  Examples of this recently drilled mineralization (21C-HW Zone) include 4.65 g/t Au, 11 g/t Ag (4.80 g/t AuEq) over 30.50 m (SK-20-780), 4.33 g/t Au, 13 g/t Ag (4.50 g/t AuEq) over 20.05 m (SK-20-692), and 1.39 g/t Au, 8 g/t Ag (1.49 g/t AuEq) over 29.25 m (and SK-20-698).

A subvertical, reactivated synvolcanic structure, this newly documented zone of discordant, replacement-style mineralization occurs uncharacteristically in the hanging-wall andesites and interflow sediments above the historically mined Contact Mudstones. To date, the 21C-HW Zone mineralization has been outlined over a strike length of 160 m and is open for expansion along strike and dip. Prior to the discovery of this mineralization, the only other occurrence of an economically mineralized synvolcanic structure in the hanging wall rocks of the Eskay Creek deposits occurs at the fittingly named HW (Hanging Wall) Zone, which is situated stratigraphically above the Contact Mudstones of the 21B Zone.

“Although this newly developing zone is in its infancy, there are many positive implications associated with this finding from both a resource development and exploration perspective” comments Paul Geddes, the Company’s Vice President of Exploration and Resource Development. “Firstly, this portion of the pit constrained resource was considered unmineralized waste rock due to a lack of drill hole sampling by previous operators and it will now likely translate into additional resources in the Company’s upcoming resource update, which is expected to be released this spring. Secondly, this new information clearly demonstrates that the Eskay Creek mineralizing events in the hanging wall rocks were not constrained to a single locale as exemplified by the original HW Zone. This discovery fortifies the sizable exploration potential of this large-scale mineralizing system for both near mine and regional resource expansion.”

21E Zone Continues to Validate High Tenor of Pit Constrained Mineralization
Equally as impressive are the tenor and widths that have recently been drilled in the 21E Zone as is highlighted by 27.13 g/t Au, 271 g/t Ag (30.74 g/t AuEq) over 10.00 m (SK-20-746) including impressive subintervals grading 109.00 g/t Au, 199 g/t Ag (111.65 g/t AuEq) over 1.00 m and 89.10 g/t Au, 2,450 g/t Ag (121.77 g/t AuEq) over 0.80 m. This intercept represents a 20 m step out and potential expansion of in-pit resources due to its location outside the limits of the existing resource model. The 21E Zone is situated on the eastern flank of the Eskay Creek deposits and represent a combination of primary exhalative mineralization overprinted and enriched by auriferous fluids during protracted reactivation of synvolcanic structures.

About Skeena
Skeena Resources Limited is a Canadian mining exploration company focused on revitalizing the past-producing Eskay Creek gold-silver mine located in Tahltan Territory in the Golden Triangle of northwest British Columbia, Canada. The Company released a robust Preliminary Economic Assessment in late 2019 and is currently focused on infill and exploration drilling to advance Eskay Creek to full Feasibility by the end of 2021. Additionally, Skeena continues exploration programs at the past-producing Snip gold mine.
