Skeena Discovers Additional High Grade Mineralization at Eskay Creek Albino Waste Facility Including 10.13 g/t AuEq over 16.77 metres

Receive up-to-date information about the company directly via push notification

Vancouver, BC (December 8, 2021) Skeena Resources Limited (TSX: SKE, NYSE: SKE) (“Skeena” or the “Company” - https://www.commodity-tv.com/ondemand/companies/profil/skeena-resources-ltd/ ) is pleased to report new drilling results from the 2021 Phase II Albino Waste Facility (“AWF”) investigation at the Eskay Creek gold-silver project (“Eskay Creek” or the “Project”) located in the Golden Triangle of British Columbia. This expansion program, totaling 212 m over 12 vertical drill holes, was completed utilizing an air rotary drill rig from the surface of the permitted AWF in Q4 2021. Analytical results from the recently completed drill holes are detailed in this release. Reference images are presented at the end of this release as well as on the Company’s website.

Eskay Creek AWF Phase II 2021 Highlights:

  • 90 g/t Au, 317 g/t Ag (10.13 g/t AuEq) over 16.77 m (SK-21-899)
  • 53 g/t Au, 168 g/t Ag (6.77 g/t AuEq) over 12.20 m (SK-21-901)
  • 84 g/t Au, 222 g/t Ag (8.80 g/t AuEq) over 13.72 m (SK-21-903)
  • 39 g/t Au, 156 g/t Ag (5.47 g/t AuEq) over 16.77 m (SK-21-908)
  • 76 g/t Au, 151 g/t Ag (5.77 g/t AuEq) over 16.76 m (SK-21-909)

Gold Equivalent (AuEq) calculated via the formula: Au (g/t) + [Ag (g/t) / 75]. True widths equate to 100% of reported sample lengths. 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.

 

Phase II Drilling Substantively Increases AWF Mineralization

Phase II AWF expansion drilling has been very successful in increasing the Au-Ag mineralization discovered during the Company’s initial drill program in Q1 2021. This new drilling was completed from a floating barge on the water surface of the AWF on 50 m staggered drill centers. Highlights of the drilling include SK-21-899: 5.90 g/t Au, 317 g/t Ag (10.13 g/t AuEq) over 16.77 m, SK-21-903: 5.84 g/t Au, 222 g/t Ag (8.80 g/t AuEq) over 13.72 m and are comparable in grade and width to the mineralization intersected in the Phase I program. Courtesy of this expansion drilling, mineralization within the AWF has now been increased to an area measuring 350 m by 125 m. The remainder of the AWF is untested by drilling and remains open for expansion.

To date, the combined Phase I and Phase II programs have intersected a mineralized horizon averaging 13.20 m (true thickness) across 20 drill holes with length weighted grades averaging 4.03 g/t Au, 163 g/t Ag (6.21 g/t AuEq), 39 ppm Hg, 331 ppm As and 922 ppm Sb. The length weighted concentrations of Hg, As and Sb from the combined AWF programs are, to date, consistent with the Company’s pit constrained Mineral Resource Estimate (MRE) for the in situ Eskay Creek deposits.

Current Status and Next Steps

The Company anticipates continuing the Phase II program in early Q1 2022 with two drill rigs from the ice surface once the engineered ice thicknesses at the AWF meets safety requirements. Staggered 50 m drill spacings are expected to be completed to determine the extents of the mineralization followed by infill on 25 m centers.

 

Albino Waste Facility Discussion

Situated west of the Eskay Creek mine site, the Albino Waste Facility was utilized by former operators as a subaqueous repository for mine waste and included both development waste rock as well as mill tailings. It is estimated that approximately 2 million tonnes of waste rock and tailings material was deposited into the AWF during the previous operations at Eskay Creek.

During historical operations, the underground mine development was largely driven in the often-mineralized footwall rhyolite sequences below the mined contact mudstone. Although these rocks possessed variable Au-Ag tenor, former operators considered the rhyolite hosted mineralization uneconomic due to the high cutoff grades required at the time. Hence, this development rock was transferred to the AWF for subaqueous deposition.

Cautionary note to U.S. Investors concerning estimates of mineral reserves and mineral resources

Skeena’s mineral reserves and mineral resources included or incorporated by reference herein have been estimated in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) as required by Canadian securities regulatory authorities, which differ from the requirements of U.S. securities laws. The terms “mineral reserve”, “proven mineral reserve”, “probable mineral reserve”, “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are Canadian mining terms as defined in accordance with NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) “CIM Definition Standards – For Mineral Resources and Mineral Reserves” adopted by the CIM Council (as amended, the “CIM Definition Standards”). The U.S. Securities and Exchange Commission (the “SEC”) has mineral property disclosure rules in Regulation S-K Subpart 1300 applicable to issuers with a class of securities registered under the Securities Exchange Act of 1934 (the “Exchange Act”), which rules were updated effective February 25, 2019 (the “SEC Mineral Property Rules”) with compliance required for the first fiscal year beginning on or after January 1, 2021. Skeena is not required to provide disclosure on its mineral properties under the SEC Mineral Property Rules or their predecessor rules under SEC Industry Guide 7 because it is a “foreign private issuer” under the Exchange Act and entitled to file reports with the SEC under MJDS.

The SEC Mineral Property Rules include terms describing mineral reserves and mineral resources that are substantially similar, but not always identical, to the corresponding terms under the CIM Definition Standards. The SEC Mineral Property Rules allow estimates of “measured”, “indicated” and “inferred” mineral resources. The SEC Mineral Property Rules’ definitions of “proven mineral reserve” and “probable mineral reserve” are substantially similar to the corresponding CIM Definition Standards. Investors are cautioned that, while these terms are substantially similar to definitions in the CIM Definition Standards, differences exist between the definitions under the SEC Mineral Property Rules and the corresponding definitions in the CIM Definition Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that Skeena may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had Skeena prepared the mineral reserve or mineral resource estimates under the standards adopted under the SEC Mineral Property Rules.

In addition, investors are cautioned not to assume that any part or all of Skeena’s mineral resources constitute or will be converted into reserves. These terms have a great amount of uncertainty as to their economic and legal feasibility. Accordingly, investors are cautioned not to assume that any “measured”, “indicated”, or “inferred” mineral resources that Skeena reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an “inferred mineral resource” will ever be upgraded to a higher category. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or prefeasibility studies, except in rare cases where permitted under NI 43-101.

For these reasons, the mineral reserve and mineral resource estimates and related information presented herein may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the U.S. federal securities laws and the rules and regulations thereunder.

Gold Equivalent (AuEq) calculated via the formula: Au (g/t) + [Ag (g/t) / 75]. True widths equate to 100% of reported sample lengths. 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.
