Eastern Extension of Twin Zone Also Yields 50.21 g/t Gold over 2.00 Metres

Vancouver, BC (January 8, 2018) Skeena Resources Limited (TSX.V: SKE) (“Skeena” or the “Company”) is pleased to announce additional drill results from 11 holes at the Company’s Snip gold project (“Snip”) located in the Golden Triangle of British Columbia. The 2017 underground drill program finished on December 16, 2017 with a total of 8,650 metres drilled over 62 holes. Assays are still pending for 34 holes.

Cross sections and drill hole data are available on the Company’s website. A detailed table of length-weighted gold composites is presented at the end of this news release.

High Grades Intersected at Twin Zone East

Targeting the eastern extension of the Twin Zone on Section 4860E, drill hole UG17-040 intersected 50.21 g/t Au over 2.00 metres while 40 metres up dip, drill hole UG17-030 intersected 12.84 g/t Au over 2.90 metres. On the same section 110 metres further up dip, drill hole UG17-039 intersected two additional intersections grading 20.17 g/t Au over 2.40 metres and 14.40 g/t Au over 1.55 metres. During historical production at the Snip mine, the Twin Zone comprised the bulk of the produced ounces and ranged in width from 0.5 to 15.0 metres.

Supplementary results on section 4860E include drill hole UG17-030 which intersected 21.77 g/t Au over 7.2 metres, including 133.00 g/t Au over 1.00 metres. This newly discovered mineralization may indicate a new shear zone located between the Twin Zone and 150 Vein that warrants follow-up.

412 Zone Drilling

Section 4930E was drilled with four fanned drill holes to confirm the historical drilling in the newly defined 412 Zone. Highlights include drill hole UG17-018 which intersected 22.01 g/t Au over 1.90 metres as well as 7.99 g/t Au over 3.00 metres. Located 80 metres down dip of UG17-018, drill hole UG17-020 intersected 132.00 g/t Au over 0.50 metres. The 412 Zone appears to be a series of parallel, high-grade shears located in the footwall, below the Twin Zone and 150 Veins in an area without previous mining.

Skeena’s CEO, Walter Coles Jr. commented, “We are delighted by the drill results to date from Snip as we continue to see grades and widths that are consistent with historical results. The most recent drill assays from the 412 Zone are particularly exciting as this area was never mined and we’ve been able to expand the mineralized zone. Once all results from the 2017 underground drill program have been received we will announce detailed plans for further underground drilling and surface drilling in 2018.”

Additional assay results are expected shortly. A Phase 2 underground drill program is expected to commence in February with surface drilling planned for summer 2018.

Quality Assurance and Quality Control

A rigorous chain-of-custody and quality assurance/quality control program, consisting of the insertion of certified standard control samples, duplicates and blanks, was applied to the NQ 2-diameter, sawn half-core samples. Sample preparation and analyses for 2017 samples were completed at Activation Labs in Kamloops, B.C. Gold is determined by 50-gram fire assay followed by an atomic absorption finish, or by gravimetric finish for samples over 10 g/t. Silver and other elements are determined by an ICP analysis following aqua regia digestion. Samples with over 100 g/t silver, 0.5% lead or 1% zinc are re-analyzed by a 4-acid digestion followed by ICP-OES.
