Skeena Intersects 5.71 g/t AuEq over 92.15 m at Surface at Eskay Creek
Vancouver, BC (December 5, 2018) Skeena Resources Limited (TSX.V: SKE, OTCQX: SKREF) (“Skeena” or the “Company”) is pleased to announce additional Au-Ag drill results for eight holes from the recently completed Phase I surface drilling program at the Eskay Creek Project (“Eskay Creek”) located in the Golden Triangle of British Columbia. The multifaceted Phase I program was performed in the 21A, 21C and 22 Zones. Assays reported in this release are from the 21C Zone; assays from the remaining 21A and 22 Zones will be released when available. Reference images are presented at the end of this release as well as on the Company’s website.
Eskay Creek 21C Zone Phase I Drilling – Current Highlights

- 4.02 g/t Au, 83 g/t Ag (5.12 g/t AuEq) over 11.25 m (SK-18-027)
- 9.86 g/t Au, 92 g/t Ag (11.10 g/t AuEq) over 14.34 m (SK-18-029)
- 7.36 g/t Au, 1,189 g/t Ag (23.22 g/t AuEq) over 14.55 m (SK-18-031)
- 6.39 g/t Au, 157 g/t Ag (8.48 g/t AuEq) over 27.50 m (SK-18-031)
- 4.23 g/t Au, 314 g/t Ag (8.42 g/t AuEq) over 14.50 m (SK-18-032)
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 were nulled to a value of zero.
21C Zone Phase I Drilling – Discussion
The 2018 Phase I program in the 21C Zone was principally directed at collecting new material for an upcoming metallurgical optimization study. Historical drilling in this zone is tightly-spaced and sufficient for reporting dominantly indicated resources (see Resource Estimate for Eskay Creek reported September 17 2018). Reported core lengths represent 80-100% of true widths and are supported by well-defined mineralization geometries derived in conjunction with historical drilling intercepts.
A total of eight drillholes were fanned from a single collar location and totaled 2,012.6 m. Modelled mineralization and geology were predictably intersected and demonstrated excellent reconciliation of historically drilled grades and widths.
The 21C Zone displays two styles of mineralization, which is consistent with the other mineralized zones that comprise the Eskay Creek deposits. High-grade mineralization with an epithermal signature is spatially associated with clastic mudstones that occur at the contact between the hangingwall basalts and footwall rhyolites. Syngenetic, feeder-style mineralization is present in strongly-altered rhyolites below the contact mudstones.
Samples collected from this program will be utilized to generate spatially distributed master composites that will inform the metallurgical optimization studies in H1 2019.
About Eskay Creek
In December 2017, Skeena secured an option to acquire 100% interest in the Eskay Creek property. Discovered in the Golden Triangle in 1988, the former Eskay Creek mine produced approximately 3.3 million ounces of gold and 160 million ounces of silver at average grades of 45 g/t gold and 2,224 g/t silver. Eskay Creek was once the world’s highest-grade gold mine and fifth-largest silver mine by volume.
A precious and base metal-rich volcanogenic massive sulphide (VMS) deposit, Eskay-style mineralization has been the focus of considerable exploration activity in the Golden Triangle dating back to 1932. Exploration programs in 1988 led to the discovery of the 21A and 21B zones, followed by underground development of the 21B zone starting in 1990 with the official opening of the Eskay Creek mine in 1994. Over the 14-year life of the mine, approximately 2.2 million tonnes of ore were mined with cut-off grades ranging from 12 to 15 g/t AuEq for mill ore and 30 g/t AuEq for direct shipping smelter ore.
Eskay is endowed with excellent infrastructure including all-weather road access and proximity to the new 287-kilovolt Northwest Transmission Line. The Property consists of 8 mineral leases, 2 surface leases and several unpatented mining claims totaling 6,151 hectares.
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 Economic Assessment on the GJ copper-gold porphyry project.

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, 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 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.
