TORONTO, ON / ACCESSWIRE / January 18, 2023 / Eskay Mining Corp. (“Eskay” or the “Company”) (TSXV:ESK)(OTCQX:ESKYF)(Frankfurt:KN7)(WKN:A0YDPM) is pleased to announce it has confirmed the presence of a precious metal-rich volcanogenic massive sulfide (“VMS”) mineralized system at Tarn Lake-Scarlet Knob in the northeastern part of its 100% controlled Consolidated Eskay Property in the Golden Triangle, British Columbia.
- During the 2022 exploration campaign, Eskay Mining’s geologic team confirmed the presence of a major new precious metal-rich VMS mineralized system at Scarlet Knob-Tarn Lake.
- A spot rock chip sample collected at the Scarlet Knob VMS target on the eastern margin of Bruce Glacier has yielded 56.9 g/t Au and 154 g/t Ag. This sample displays sulfide mineralogy and textures indicative of a VMS origin and, importantly, is hosted by a stratigraphic unit that hosts the main Eskay Creek deposit located approximately 7km to the west.
- Additional spot rock chip samples collected by Eskay’s exploration team at Scarlet Knob and Tarn Lake in 2022 as well as recently identified legacy sample data confirms the presence of robust Au- and Ag-rich VMS mineralization along a northeast trending zone approximately 500m long. Gold grades of these other samples range from less than 0.1 g/t up to 56.6 g/t and silver grades range from less than 1 g/t up to 142 g/t.
- A spot rock chip sample collected along the western margin of Bruce Glacier at Tarn Lake yielded 9.2 g/t Au and 9.3 g/t Ag. Its visual appearance and mineralogy are nearly identical to that of the high-grade sample collected approximately 800m to the east at Scarlet Knob.
- Additional spot rock chip samples collected by Eskay’s exploration team at Tarn Lake in 2022 as well as recently identified legacy sample data confirms the presence of significant Au- and Ag-rich VMS mineralization over an area approximately 300m across. Gold grades of these other samples range from less than 0.1 g/t up to 7.8 g/t and silver grades range from less than 1 g/t up to 174 g/t.
- Preliminary results from the first ever drill holes completed at Tarn Lake include 4.10 g/t Au and 98.30 g/t Ag (5.39 g/t Au Eq) over 5.43m within 2.47 g/t Au and 72.20 g/t Ag (3.42 g/t Au Eq) over 11.34m within 0.80 g/t Au and 22.97 g/t Ag (1.10 g/t Au Eq) over 41.41m in hole TN22-10 providing drill confirmation of a significant new VMS discovery.
- Eskay Mining’s geologic team think that mineralization at Tarn Lake and Scarlet Knob potentially connect under the rapidly receding terminus of Bruce Glacier. Previously reported BLEG (stream sediment) geochemical anomalism displayed by several samples in this region may be derived in part from the Scarlet Knob-Tarn Lake VMS system.
- Given the Scarlet Knob-Tarn Lake VMS system shares strong similarities to the Eskay Creek deposit, Eskay Mining is planning to conduct first ever drilling at Scarlet Knob as well as aggressive follow up drilling at Tarn Lake in 2023.
“A major focus of Eskay Mining’s 2022 exploration program was identifying new precious metal-rich VMS mineralization in underexplored areas of the large Consolidated Eskay Property,” commented Dr. John DeDecker, VP of Exploration for Eskay Mining Corp. “At Scarlet Knob-Tarn Lake, our team has confirmed the presence of a second major trend of Au- and Ag-rich VMS mineralization at the northern end of the Eastern anticline which runs parallel to the Eskay anticline that hosts the world class Eskay Creek deposit located approximately seven km to the west. Our rock chip samples from this area, some of which returned bonanza gold grades, display a similar appearance to mineralization at Eskay Creek. Importantly, the host rock at Scarlet Knob-Tarn Lake is the Eskay rhyolite, the same stratigraphic host unit at Eskay Creek. Preliminary results from our maiden drill program at Tarn Lake confirm the discovery of a significant zone of Au- and Ag-rich VMS mineralization. We are particularly excited about the potential connectivity between Tarn Lake and Scarlet Knob. We are planning maiden drilling at Scarlet Knob and aggressive follow up drilling at Tarn Lake in 2023.”
“Over the past three years, our geological team has made extraordinary progress toward our mission of discovering new high-grade VMS deposits across the Consolidated Eskay Property,” commented Mac Balkam, CEO of Eskay Mining. “Our large property has the right geology to host deposits comparable to the original Eskay Creek Mine, and we all know that VMS deposits typically occur in clusters. Our team’s 2022 work in the Scarlet Ridge-Tarn Lake trend, 7 Kilometers due east of the original mine, shows very encouraging gold and silver results from both rock chip samples and drill core. A rock chip sample from Scarlet Knob returned 56.9 g/t gold and 154 g/t silver, has an appearance similar to high-grade mineralization at Eskay Creek and is hosted by the same rock units as those at Eskay Creek. When plotted with legacy results including a 56.6 g/t gold and 32 g/t silver sample, a 500m long high-grade trend is now evident, with additional samples ranging from 1-10 g/t Au extending a further 900 m to the northeast. Straight across Bruce Glacier and 800m to the west, rock chip samples have defined a 300m wide zone of gold- and silver-rich VMS mineralization. We were able to get a few widely spaced holes in this target before the end of season and were able to confirm this discovery with solid drill results. There are compelling signs that Scarlet Knob and Tarn Lake connect under the toe of Bruce Glacier. I am delighted that our 2022 results validate our thesis that Eskay Consolidated has multiple precious metal-rich VMS targets with potential like that of the original mine. The Eskay team is very excited about conducting follow up work at Scarlet Knob-Tarn Lake as well as at TV-Hexagon-Mercury and SIB-Lulu. The stage is set for an exciting 2023 exploration program.”
Tarn Lake and Scarlet Knob
During the 2022 exploration campaign, a 300m wide zone of Au- and Ag-rich VMS mineralization was discovered by Eskay Mining’s geologic team at Tarn Lake (Figure 1). The highest-grade spot rock chip sample, collected along the western margin of Bruce Glacier, yielded 9.2 g/t Au and 9.3 g/t Ag (Figure 2). Additional spot rock chip samples collected at Tarn Lake in 2022 as well as recently identified legacy sample data bear gold grades ranging from less than 0.1 g/t up to 7.8 g/t and silver grades ranging from less than 1 g/t up to 174 g/t.
Near the end of the 2022 diamond drill program, Eskay Mining’s geologic team completed the first ever drilling at Tarn Lake, a series of widely spaced holes targeting areas underneath the location from which promising surface samples had recently been collected (Figure 3). Preliminary results from the first ever drill holes completed at Tarn Lake include:
- 4.10 g/t Au and 98.30 g/t Ag (5.39 g/t Au Eq) over 5.43m within 2.47 g/t Au and 72.20 g/t Ag (3.42 g/t Au Eq) over 11.34m within 0.80 g/t Au and 22.97 g/t Ag (1.10 g/t Au Eq) over 41.41m in hole TN22-10, and
- 3.96 g/t Au and 11.86 g/t Ag (4.12 g/t Au Eq) over 1.91m within 1.90 g/t Au and 7.94 g/t Ag (2.00 g/t Au Eq) over 6.95m in hole TN22-12.
A summary of significant preliminary assays from Tarn Lake is presented in a table below. Remaining assays from Tarn Lake drill holes will be reported once they have returned from the lab.
Mineralization at Tarn Lake is associated with sets of east-west trending andesite dikes, interpreted to represent VMS syn-volcanic feeder structures, and occurs as sub-seafloor sulfide replacement of favorable stratigraphic horizons (Figures 4 and 5). It is hosted by the Eskay rhyolite, one of the primary host rocks at the Eskay Creek mine. Assay results show that both the semi-massive and disseminated sulfide mineralization are Au- and Ag-bearing, an encouraging sign indicating that precious metal mineralization may be more extensive in this area.
Spot rock chip sampling at Scarlet Knob in 2022 yielded a notable high-grade sample grading 56.9 g/t Au and 154 g/t Ag. Additional spot rock chip samples collected by Eskay’s exploration team as well as recently identified legacy sample data bear gold grades ranging from less than 0.1 g/t up to 56.6 g/t and silver grades range from less than 1 g/t up to 142 g/t. These collectively define a northeast trending zone approximately 500m long.
Rock chip samples from Scarlet Knob, on the eastern flank of Bruce Glacier, bear a strong resemblance to those collected at Tarn Lake, on the western side, some 800m distant (Figures 6 and 7). Like Tarn Lake, mineralization at Scarlet Knob is hosted by the Eskay rhyolite. Eskay Mining’s geologic team thinks there is a likelihood that VMS mineralization connects between these two areas underneath the toe of the rapidly receding Bruce Glacier. Further exploration will focus on establishing connectivity along this ~1 km long east-west corridor. Ability to drill through ice in this area is being examined.
Scarlet Ridge and Scarlet Valley
In 2022, Eskay Mining’s geologic team identified zones of stockwork and replacement-style VMS mineralization at Scarlet Ridge and Scarlet Valley. Mineralization is associated with east-west trending andesite dikes interpreted to be syn-volcanic VMS feeder structures. Surface sampling and diamond drilling were conducted at both locations, both techniques yielding anomalous gold and silver grades (Figures 8, 9 and 10). Significant drill results are summarized in a table below.
Eskay Mining’s geologic team views the hydrothermal alteration and anomalous precious metal concentrations at Scarlet Ridge and Scarlet Valley to be distal components of the VMS system centered around Scarlet Knob-Tarn Lake. Therefore, emphasis will be placed on follow up exploration around the latter location in 2023. SkyTEM data indicates the presence of a significant conductive feature immediately southwest of Tarn Lake in need of field follow up examination (Figure 11).
2022 Exploration Program
The fundamental goal of the 2022 exploration program was to identify new precious metal-rich VMS deposits across the Consolidated Eskay Project through early-stage work including mapping and geochemical sampling, and more advanced work including widely spaced drilling. During the 2022 exploration season, Eskay Mining successfully completed 29,500m of diamond drilling along the TV-Jeff corridor and along the Scarlet Ridge-Tarn Lake trend.
Drill results discussed in this news release come from holes drilled along the Scarlet Ridge-Tarn Lake trend. Significant assays from fifteen drill holes that are part of this release are tabulated in a table below. Holes with no significant results are not listed in this table.
Further analytical data is expected back over the next few weeks. This includes assays from additional drill holes drilled along the Scarlet Ridge-Tarn Lake trend, holes drilled at the TV deposit and analyses from substantial numbers of soil, surface rock chip, and infill BLEG samples from across the project. These will be presented to the market as they become available.
Au Eq and Ag Eq Calculations and True Width:
Note on use of Au eq (Au eq=Au+Ag/76) and Ag eq (Ag eq=Au*76+Ag): Mineralization at the TV and Jeff deposits displays similar characteristics and mineralogy to the Eskay Creek deposit and therefore for Au eq, and Au:Ag, a ratio of 76:1 is used and Au eq and Ag eq values are deemed to be reasonable based on assumed gold recovery (84.2%) and silver recovery (87.3%) as reported in the Eskay Creek Project NI 43-101 Technical Report and Prefeasibility Study, British Columbia, Canada, Effective Date: 22 July, 2021, Prepared for: Skeena Resources Ltd., Prepared by: Absence Engineering Canada Inc.
True widths of reported intercepts are not fully understood at this time but given the moderately dipping tabular nature of these deposits and the steep angle of drilling, Eskay geologists estimate true widths represent approximately 70-90% of the reported drill intercept lengths.
QA/QC, Methodology Statement:
Halved HQ drill core samples are submitted to ALS Geochemistry in Terrace, British Columbia for preparation and analysis. ALS is accredited to the ISO/IEC 17025 standard for gold assays. All analytical methods include quality control standards inserted at set frequencies. The entire sample interval is crushed and homogenized, 250 g of the homogenized sample is pulped. All samples were analyzed for gold, silver, mercury, and a suite of 48 major and trace elements. Analysis for gold is by fire assay fusion followed by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) on 30 g of pulp. Analysis for silver is by fire assay and gravimetric analysis on 30 g of pulp. Mercury is analyzed using the trace Hg Inductively Coupled Plasma Mass Spectroscopy (ICP-MS) method. All other major and trace elements are analyzed by four-acid digestion followed by ICP-MS.
Historical rock chip sample data is sourced from Assessment Report AR19675 by Granges dated February 7, 1990. Eskay Mining is unable to fully verify this data, and it should be treated as such by the reader.
