  • 284g/t Ag, 0.57% Cu, 12.3% Pb, and 11.0% Zn over 2.5m including 383g/t Ag, 0.82% Cu, 16.6% Pb, and 10.3% Zn over 1.5m

VANCOUVER, BC / ACCESSWIRE / January 31, 2022 / Core Assets Corp., ("Core Assets" or the "Company") (CSE:CC)(FSE:5RJ)(OTCQB:CCOOF) is pleased to announce channel sample results from five outcropping carbonate replacement massive sulphide occurrences at the Jackie Target, part of the 6.6km long by 1.8km wide Silver Lime carbonate replacement deposit ("CRD") prospect within the Company's 100% controlled Blue Property (the "Property"), in the Atlin Mining District of British Columbia. Sawn channel samples were collected as part of Core Assets' 2021 maiden field campaign at Silver Lime. Additional 2021 channel sampling results from the nearby Grizzly Discovery Zone and Sulphide City Target are expected to return in February 2022.

Highlights

  • All channel samples were collected from zones of CRD massive sulphide mineralization. Unlike vein-hosted deposits, CRDs typically manifest as continuous deposits of interconnected bedding parallel sulphide replacement deposits called mantos and crosscutting structurally controlled sulphide pipes called chimneys. The scale of CRD systems can potentially extend for multi-kilometres around their source, typically a causative mineralized porphyry system. The Silver Lime prospect demonstrates such scale (Figure 1).
  • As a first pass attempt to evaluate the grade of replacement sulphide mineralization at Jackie, five sulphide bodies, all outcropping within an area measuring 400 x 380 meters, were channel sampled at an average sample interval of 0.5m (Figure 2). All five sulphide bodies yielded high-grade base metal-silver results including:
    • 486g/t Ag, 0.36% Cu, 9.4% Pb, and 13.0% Zn over 1.4m including 1,080g/t Ag, 0.36% Cu, >20% Pb, and 13.2% Zn over 0.5m in channel CH21-14 (Figure 3).
    • 336g/t Ag, 0.26% Cu, 7.9% Pb, and 9.5% Zn over 1.25m including 851g/t Ag, 0.29% Cu, >20% Pb, and 9.7% Zn over 0.35m in channel CH21-11.
    • 284g/t Ag, 0.57% Cu, 12.3% Pb, and 11.1% Zn over 2.5m including 383g/t Ag, 0.82% Cu, 16.6% Pb, and 10.3% Zn over 1.5m in channel CH21-13.
    • 200g/t Ag, 0.24% Cu, 6.6% Pb, and 13.5% Zn over 1.5m including 516g/t Ag, 0.10% Cu, 18.6% Pb, and 17.0% Zn over 0.5m in channel CH21-12.
    • 29g/t Ag, 0.20% Cu, 1.3% Pb, and 11.4% Zn over 3.8m in channel CH21-15.
  • Of the 22 channel samples collected, 12 samples assayed greater than 100g/t Ag, 16 greater than 0.20% Cu, 14 greater than 1.0% Pb, and all channel samples collected assayed greater than 5.0% Zn (Table 1).
  • Remaining 2021 channel sampling results from the Grizzly Discovery Zone and Sulphide City, both CRD targets nearby Jackie, are expected to be released in February 2022.

Core Assets' President and CEO Nick Rodway comments, "The 2021 maiden channel sampling program at the Silver Lime prospect on Core Assets' Blue Property was designed to assess the grade of massive sulphide occurrences discovered and mapped early in the field program. These sawn channel results confirm assays of early grab samples taken upon discovery of these remarkable outcropping sulphide bodies. All five sulphide bodies sampled at Jackie have confirmed high-grade mineralization within an area of 400 x 380m. Our working thesis is that these massive sulfide bodies are part of an interconnected network of sulphides occurring in the subsurface and likely linked with the nearby Grizzly Discovery Zone and Sulphide City target. Once we see channel results from these other two areas, we should have a very good understanding of the grades that this large CRD system can yield, and we may also begin to see a geochemical vector that points towards the causative porphyry underlying this system. We are already planning an aggressive diamond drilling program for 2022 to test this CRD system and porphyry exploration model."

2021 Channel Sampling - Jackie Target

The Jackie Target, part of the Silver Lime Prospect within Core Assets' Blue Property, consists of numerous massive- to semi-massive sulphide occurrences each measuring up to 30 metres long and 6 metres wide. These sulphide occurrences comprise an approximate area of 400 metres by 380 metres, within the extensive 6.6-kilometre by 1.8-kilometre mineralized zone that remains open. During 2021, 22 samples were collected across five sawn channels ranging from 1.25 metres to 3.8 metres in length. Significant Ag, Cu, Pb, and Zn values returned from all five sulphide bodies that were channel sampled. These massive sulphide pipes appear to replace favorable limestone beds where they are intersected by prominent northeast-southwest trending faults (Figure 1). Of the 22 channel samples collected, 12 samples assayed greater than 100g/t Ag, 16 greater than 0.20% Cu, 14 greater than 1.0% Pb, and all channel samples assayed greater than 5.0% Zn.

The best silver results from a channel sampled at Jackie came from channel CH21-14 which assayed 486g/t Ag, 0.36% Cu, 9.4% Pb, and 13.0% Zn over its entire length of 1.4m. The best combined Pb-Zn result, 23.5%, came from channel CH21-13 which assayed 284g/t Ag, 0.57% Cu, 12.3% Pb, and 11.1% Zn over 2.5m. This channel also graded highest in Cu, 0.57%. Channel CH21-11 returned 1.25m of 336g/t Ag, 0.26% Cu, 7.9% Pb, and 9.5% Zn, including 0.35 metres of 851g/t Ag, 0.29% Cu, >20% Pb, and 9.7% Zn.

To date, 263 historic and modern surface samples have been collected at the Jackie Target. In total, 52 samples have returned assay values greater than 100g/t Ag, 58 greater than 0.20% Cu, 41 greater than 5.0% Pb, and 76 greater than 5.0% Zn. At this time, geologists from Core Assets speculated that this zone of high-grade channel and grab samples is located less than one kilometre east-northeast of a possible causative porphyry ("hub").

Applying an exploration model in which the Jackie CRDs form "spokes" and the causative porphyry represents the "hub," Core Assets' geologists speculate that ore fluids migrated away from the porphyry heat and metal source along structurally controlled networks of faults and fractures. During fluid propagation, ore fluids mixed with fluids from other sources (i.e., meteoric/connate waters or basin brines) resulting in precipitation of sulphide bodies that formed through fluid neutralization as ore fluids interacted with, and dissolved limestone. This resulted in a hub and spoke like geometry with the porphyry in the center and the CRDs forming spokes surrounding it. Such a hub and spoke model is the case at such systems as the world-class Bingham Canyon porphyry-skarn-CRD deposits in Utah, USA.

About the Jackie Target

The Jackie Target is part of an extensive Zn-Pb-Ag-Cu-Bi CRD system at Silver Lime. Favourable limestone beds host the majority of carbonate replacement style mineralization, and a wide range of intermediate-to-felsic volcanic and plutonic rocks and gneissic country rocks are also affected by massive-to-disseminated base metal sulphide mineralization. Massive sulphide composition and replacement textures observed in samples collected from Jackie are characteristic of significant, world class CRDs. These consist of an early sphalerite-chalcopyrite assemblage overlapped with a later phase of galena and/or Fe-sulphides (pyrite, pyrrhotite). The presence of fugitive calcite and opaque sphalerite suggests that the Jackie Target sits within close proximity to the source of ore-forming fluids. The presence of pyrite/marcasite replacing early pyrrhotite is indicative of a long-lived mineralizing CRD system. Core Assets' geologists noted that massive sulphide textural complexity at Silver Lime is most intense in areas closest to the inferred porphyry "hub".

QA/QC and Sample Preparation

All channel samples were cut in the field using a gas-powered diamond blade saw. Locations were marked with spray paint across presumed mineralized horizons and parallel lines were cut approximately 5 cm apart. Perpendicular lines were then cut at approximately 50 cm sample intervals or less. A hammer and chisel were then used to remove the rock from the channels and the samples were placed in pre-labelled sample bags. Locations were obtained using a handheld GPS and azimuth measurements were collected using a compass. Samples were stored in 5-gallon pails in a secure location until ready for shipment. Quartz blanks were inserted approximately every 25 samples as part of QA/QC procedures.

All rock samples and quartz blanks were shipped by ground to ALS Geochemistry in Whitehorse, YT for multielement analysis (including Ag) by four-acid digestion with ICP-MS instrumentation (package ME-ICP61) and Au, Pd, Pt by fire assay (package PGM-ICP27). Any overlimit for Ag, Cu, Pb and Zn were analyzed using the applicable assay package ME-OG62. No certified reference materials were submitted for analysis with the Company relying on the laboratories internal QA\QC in this regard.

About Core Assets Corp.

Core Assets Corp. is a Canadian mineral exploration company focused on the acquisition and development of mineral projects in British Columbia., Canada. The company currently holds 100% title ownership in the Blue Property, which covers a land area of ~108,337 Ha (~1,083 km²). The project lies within the Atlin Mining District, a well-known gold mining camp located in the unceded territory of the Taku River Tlingit First Nation. The Property hosts a major structural feature known as The Llewellyn Fault Zone ("LFZ"). This structure is approximately 140km in length and runs from the Tally-Ho Shear Zone in the Yukon, south through the property to the Alaskan Panhandle Juneau Ice Sheet in the United States. Core Assets believes that the south Atlin Lake area and the LFZ has been neglected since the last major exploration campaigns in the 1980's. The LFZ plays an important role in mineralization of near surface metal occurrences across the property. The past 50 years have seen substantial advancements in the understanding of porphyry, skarn, and carbonate replacement type deposits both globally and in BC's Golden Triangle. The company has leveraged this information at the Blue Property to tailor an already proven exploration model and believes this could facilitate a major discovery. Core Assets is excited to become one of Atlin Mining District's premier explorers where its team believes there are substantial opportunities for new discoveries and development in the area.
