VANCOUVER, BC / ACCESSWIRE / February 12, 2019 / Skeena Resources Limited (TSX.V: SKE, OTCQX: SKREF) ("Skeena" or the "Company") is pleased to provide shareholders with an update on exploration and development activities for the Company's projects located in the Golden Triangle of British Columbia, and an outlook for 2019.
2018 Advancements
In September 2018 (see news release dated September 17, 2018) the Company announced an initial resource estimate for the high-grade, past-producing Eskay Creek Project ("Eskay Creek") supported solely by historical data. Phase I drilling performed by the Company in 2018 was not included in this estimate but will be included in a resource update expected inQ1 2019.
At Eskay Creek, pit constrained Indicated Resources include 207,000 AuEq ounces within 1.09 Mt grading 5.9 g/t AuEq, and additional Inferred Resources of 589,000 AuEq ounces contained within 4.26 Mt at an average grade of 4.3 g/t AuEq.
Underground Indicated Resources include 814,000 AuEq ounces contained within 2.51 Mt grading 10.1 g/t AuEq, and an additional underground Inferred Resources of 261,000 AuEq ounces contained within 0.81 Mt grading 10.0 g/t AuEq.
The Eskay Creek deposits represent a shallow water, bimodal volcanic sequence hosted in a fault bounded basin with an epithermal VMS signature. Rhyolite facies volcanics ("Rhyolite") are overlain by mafic volcanics with a clastic mudstone ("Mudstone") occurring at the contact between the two volcanic episodes. This Mudstone represents the period of quiescence between the two volcanic events and is spatially and temporally related to the main mineralizing event at Eskay Creek. The epithermal suite of elements (Hg-Sb-As) and bonanza precious metal grades dominantly occur at this interface but are not homogenously distributed throughout the Mudstone. Rather, they are spatially associated with vents fed from underlying synvolcanic feeders.
Due to the higher precious metal tenor of the Mudstone-hosted mineralization, the vast majority of historical production at Eskay Creek occurred within this rock type whilst the Rhyolite-hosted feeder style mineralization was less developed due to its lower Au-Ag grades. Rhyolite-hosted mineralization is not enriched in Hg-Sb-As and was often blended with Mudstone-hosted zones to reduce smelter penalties for the on-site milled concentrates and Direct Shipped Ore (DSO).
Resources for Eskay Creek calculated in 2018 by the Company were categorized by rock type (Rhyolite or Mudstone) in Tables 1 and 2 below. On a tonnage weighted basis, pit constrained resources in the 21A and 22 Zones average 85% Rhyolite and 15% Mudstone. Underground resources closely mimic these ratios with 75% hosted within Rhyolite and 25% hosted within Mudstone.

2019 Outlook - Eskay Creek
An updated resource estimate is scheduled for Q1 2019, which will include all data for estimating both underground and pit constrained resources. Drilling performed in 2018 was designed to add confidence and upgrade inferred resources to indicated, as well as to collect spatially distributed material for representative metallurgical test work optimizations.
Blue Coast Research has been engaged by the Company to perform the metallurgical work and process optimizations that will be used in a Preliminary Economic Assessment ("PEA") on Eskay Creek. This phase of metallurgical test work is anticipated to be finalized by Q2 2019 and will support an upcoming PEA which is scheduled for completion in Q3 2019.
Phase II drilling at Eskay Creek will be focused on further upgrading of resources to the indicated category for future economic analyses, as well as continued exploration and expansion of Rhyolite-hosted feeder structures, analogous to the 21C and 22 Zones.
2019 Outlook - Snip
Exploration and development activities in 2019 on the Company's 100% owned Snip Gold Project ("Snip") will largely focus on exploratory regional drill assessments and follow-up drilling in the newly discovered 200 Footwall structure. Regional targeting is designed to assess and expand upon historically defined mineralization that was not extended, as well as grassroots exploration of previously untested geochemical anomalies.
