Eskay Mining appoints Mirza as geophysical adviser

2023-03-13 12:47 ET - News Release

Mr. Mac Balkam reports


Eskay Mining Corp. has added Riaz Mirza, MSc, as geophysical adviser to its exploration team. Mr. Mirza brings a wealth of experience in the application of geophysics for precious- and base-metal exploration in the Golden Triangle where he has been actively engaged in numerous projects over the past decade. Eskay Mining welcomes Mr. Mirza as the newest member of its world-class team of explorers in search of "Eskay Creek V2.0."

Riaz Mirza, founder of Simcoe Geoscience Limited, a global geophysical service provider, has significant experience exploring a variety of deposit types including volcanogenic massive sulfide ("VMS") deposits across the Golden Triangle, British Columbia. This experience, as well as Simcoe's reliance on "next-generation" geophysical data collection and processing, provides Eskay Mining with an entirely new set of tools with which to define new exploration targets for future drill testing.

Mac Balkam, CEO of Eskay Mining, commented: "Riaz and his team have been reviewing our geophysical data from our 100% controlled 602.55 sq km Consolidated Eskay project area with the goal of drawing direct comparisons to that from the original Eskay Creek precious metal-rich VMS deposit. Because VMS deposits typically occur in clusters, drawing direct comparisons of our data to that of our neighbor provides a huge step forward in our quest for discovering 'Eskay Creek V2.0.'"

John DeDecker, VP of Exploration for Eskay Mining, commented: "Using our large geophysical database, Riaz and his team immediately identified some compelling similarities between the amplitude, texture, distribution and depth of magnetic anomalies associated with the Eskay Creek deposit and multiple areas displaying such patterns across our Consolidated Eskay project. This very distinct magnetic signature associated with the ore bodies at Eskay Creek gives us a powerful tool with which to identify new VMS targets. Combined with our BLEG, rock chip, and soil geochemical data, we now have the ability to undertake much more tightly focused exploration work in 2023."

Riaz Mirza, Geophysical Advisor to Eskay Mining, noted: "We here at Simcoe Geoscience have already been able to use Eskay Mining's existing data to illuminate further potential VMS targets. Key magnetic signatures observed at the Eskay Creek deposit are visible in multiple locations across the Consolidated Eskay project telling us we have excellent discovery potential. With this work, Eskay will be able to better use its 2023 exploration budget by targeting its drilling more effectively. We here at Simcoe look forward to teaming up with Eskay's technical team to strategize our next approaches to exploration including focused mapping, sampling, drilling and perhaps other approaches across Eskay's large land holdings. We thank Eskay Mining's for the opportunity to work with their strong technical team as we pursue discovery of 'Eskay Creek V2.0.'"

Data, Methodology and Interpretation by Simcoe GeoscienceA Leapfrog model of mineralization at Eskay Creek was made utilizing publicly available data from the following sources:

Drill core assay results for Eskay Creek were obtained from Assessment Report number 18958, as well as news releases available on Skeena Resources Limited's website.

Rock chip assays for Eskay Creek were obtained from Assessment Report number 11160.Drill collar locations reported in Skeena Resources news releases were transformed from mine grid to UTM Zone 9 NAD83.Drill hole assay results in Au equivalent are graphically represented in the image in Figure 1.Airborne SkyTEM and magnetic data gathered in 2021 covering the Consolidated Eskay project and peripheral areas.

New analysis of these data show that there is a distinct magnetic signature associated with the Eskay Creek deposit that is clearly evident when a tilt derivative is applied to the magnetic data. This process re-scales the data range allowing for low amplitude magnetic features to be resolved graphically. Mineralized bodies appear sharply resolved as magnetic highs surrounded by distinct magnetic lows giving a bullseye-like appearance to the deposit (Figure 1). Eskay's geologic team interprets this distinct signature to result from deformation and metamorphism of hydrothermally altered rocks during post-mineralization tectonic events. A three-dimensional model of magnetic susceptibility shows a strong correlation between domains of high magnetic susceptibility with VMS mineralization situated along a surface defined by a magnetic susceptibility of 0.001 SI. Weaker magnetic susceptibility anomalies are associated with the 21A Zone and the 22 Zone.Comparable magnetic anomalies are observed in several areas across Eskay Mining's Consolidated Eskay property (Figures 2-4, and 6-9). A strong correlation is clearly evident between these anomalies and areas of known VMS mineralization (TV, Jeff, Scarlet-Tarn, Sib-Lulu, C10, and Virginia Lakes) as well as in areas where Au- and Ag-bearing sulfide rock chip samples have been collected along the Harrymel Valley, Eskay Anticline and the Scarlet-Tarn trends. In every case, VMS mineralization encountered by drilling occurs along the margins of the modeled 3D magnetic susceptibility volume as described above at Eskay Creek.

Based on observations from magnetic data, a new target named Maroon Cliffs has been identified in the far northeast part of the property (Figures 2-4). Legacy soil sampling on the west side of this anomaly shows strongly elevated Ag and Hg values (Assessment Report number 24155). Data from BLEG surveys conducted in 2020 and 2022 further support the prospectivity of Maroon Cliffs (Figure 5), with two Au BLEG anomalies immediately downstream from this newly identified magnetic anomaly. The presence of the VMS system, CBS Zone, occurring on Tudor Gold's property to the east along strike from Maroon Cliffs adds further support for the potential of this area. This new target will be a key focus of exploration in 2023.Although the target between Hexagon-Mercury and Jeff North has recently been identified through geologic mapping, and data from Eskay's 2021 SkyTEM survey, its magnetic signature proves compelling (Figure 6). In addition to a bullseye-like magnetic anomaly visible when the tilt derivative is applied, this target is also associated with several shallow protrusions evident in the 3D magnetic susceptibility model. Such protrusions are distinct at Eskay Creek where they are associated with mineralization. Helipads were constructed in this area in September 2022 to allow access to this rugged area in 2023.The TV-Jeff trend is associated with Eskay Creek-like magnetic anomalies (Figure 7), with the most prominent protrusions in the magnetic susceptibility model corresponding with areas of most intense Au and Ag mineralization. Notably, small protrusions in the magnetic susceptibility model between TV and Jeff correspond with anomalous Au and Ag values from sulfide rock chip samples and widely scattered drill holes. Eskay Mining's technical team suspects the intensity of magnetic susceptibility anomalies may correlate with the intensity of VMS mineralization. This appears to be the case at TV which is associated with the most pronounced magnetic anomaly in the area (Figure 8). Importantly, this magnetic anomaly continues into un-drill tested areas to the south and west of TV suggesting that VMS mineralization likely extends to these regions. This TV extension will be explored in 2023.The recently identified Scarlet-Tarn trend also appears to be associated with Eskay Creek-like magnetic anomalies (Figure 9). Extensive work in this area in 2021 and 2022 concluded that the Tarn Lake-Scarlet Knob area is underlain by the same rock units hosting the Eskay Creek deposit (e.g., the Eskay Rhyolite). High-grade Au and Ag anomalies associated with intense localized hydrothermal alteration were discovered through rock chip sampling and drilling. It was also determined that stratigraphic up is to the west meaning that the highly prospective Contact Mudstone horizon, host to the Eskay Creek deposit, is likely situated to the west of Tarn Lake. The observed trend of magnetic susceptibility anomalies extending to the west of Tarn Lake indicates this area could indeed host high-grade VMS mineralization similar to that at the Eskay Creek deposit. This area will be a primary focus of Eskay Mining's 2023 exploration program.
