VANCOUVER, BC / ACCESSWIRE / June 5, 2024 / Core Assets Corp., ("Core Assets" or the "Company") (CSE:CC)(FSE:5RJ)(OTC.QB:CCOOF) is pleased to announce the results and interpretation of a 3-Dimensional Magnetic Vector Inversion Model collected over the 2024 drilling area at the Silver Lime CRD-Porphyry Project (the "Silver Lime Project" or "Silver Lime"), central Blue Property (the "Blue Property"), Atlin Mining District of NW British Columbia.
HIGHLIGHTS
1.) Source Intrusion Discovery: The 3D magnetic model indicates that the Sulphide City Mo-Cu Porphyry Stock extends deeper and connects to a larger magnetic body measuring ~3.7 kilometres wide, which feeds at least three additional porphyry stocks beneath the Pete's CRD and AMP targets, and south of the Gally CRD target (Figure 1).
2.) Drilling Confirmation: In 2022, drillhole SLM22-006 at Sulphide City reached a depth of 471 meters, showing significant porphyry-style alteration, veining, and increased molybdenum (Mo) and copper (Cu) grades at around 315 meters depth (Figures 1, 2). Grades near the EOH returned up to 2.50% CuEq.
3.) 2024 Drilling Plan: Core Assets is fully funded for up to 5,000m of diamond drilling as well as project-wide mapping and rock sampling campaigns. We will start by drill-testing the Sulphide City Mo-Cu Porphyry Stock (80 mV/V) (Figure 1), and the potential source intrusion. Drilling is on-track to begin this week at the Silver Lime CRD-Porphyry Project.

Core Assets' President & CEO Nick Rodway commented, "Overlaps observed between our favourable magnetics, highly chargeable and conductive zones, Cu and Mo grade downhole, and the current drilled extent of the Sulphide City Mo-Cu Porphyry all point towards the continuation of the mineralized Sulphide City Porphyry to depths exceeding 1 kilometer. These overlapping datasets indicate the presence of a large, long-lived, and multi-stage, mineralized porphyry system feeding the high-grade Silver Lime skarn and CRM targets. This interpretation comes with an enhanced understanding of our 3D project geology and structures that acted as fluid pathways for the high-grade massive sulphide and epithermal mineralization observed outboard of the Sulphide City Target. Everything is on schedule, and we are excited to begin drilling this week. We'll start by testing the prospective overlap zones for porphyry Cu potential."
In early 2024, Core Assets contracted Fathom Geophysics to create a 3D magnetic inversion model utilizing the VTEM (Versatile Time Domain Electromagnetic) geophysical data collected over the Silver Lime CRD-Porphyry Project in 2021.
The 3D radial magnetic models at Silver Lime (isosurfaces; pale pink shapes in Figure 1) correlate well with highly chargeable zones below the Sulphide City, Pete's and Gally targets identified by the 2023 3D-IP (Three-Dimensional Induced Polarization) survey (high chargeability plotted as red and purple contours in Figure 1).
In 2022, SLM22-006 drill-tested the Sulphide City Mo-Cu Porphyry to a true depth of 471m and encountered strong porphyry-style alteration, veining and increased Mo and Cu grades upon intersecting the top of the highly chargeable core (80mV/V) near 320m true depth (See News Release dated December 14, 2023).
The 3D radial magnetic models (isosurface; pale pink shape in Figure 1) indicate a continuation of the Sulphide City Mo-Cu Porphyry Stock to depth where it connects to a larger magnetic body interpreted as the source intrusion (Figures 1, 3). This source intrusion measures 3.7-kilometres wide and appears to be feeding at least three additional interpreted porphyry stocks situated below the Pete's CRD and Amp targets, and 750m south of the Gally CRD Target.
Interpreted mineralized porphyry stocks (pale pink shapes) along the Pete's - Sulphide City - Gally Trend are associated with overlapping chargeable and conductive anomalies along their margins that are interpreted as probable zones of high-grade Zn-Fe-Cu massive sulphide skarn deposits.
All prospective porphyry targets presented in Figure 1, including the interpreted main source intrusion, are bound by major deep-seated faults within a 13.7km2 area (red lines in Figure 1). These structures are believed to have acted as the main pathways for the distal and widespread, high-grade massive sulphide Ag-Zn-Pb-Cu±Au carbonate replacement mineralization at the Silver Lime Project.
ADDITIONAL INFORMATION ABOUT THE 3D MAGNETIC VECTOR INVERSION (3D-MVI)
In the Winter of 2024, Fathom Geophysics Ltd. was contracted to carry out a 3D MVI on Versatile Time Domain Electromagnetic (VTEM) geophysical data obtained in 2021 for porphyry target generation and 2D and 3D structure detection. Current interpretations of the 3D amplitude, remnant magnetization, and radial symmetry inversions indicate a large, deep, buried intrusion underlying the majority of the main Silver Lime Project area. Several apparent stocks extending from the larger radial feature at depth are continuous to surface, inter-connecting each of the drilled Silver Lime targets, as well as the Amp Target, to a single large system at depth. Radially symmetrical isosurfaces from 180-720m in radius were used in this interpretation, and features are generally continuous across all relative values in the inversions.
The 3D MVI shows a possible continuation of the Sulphide City Mo-Cu Porphyry. This continuation is represented by the pale pink, magnetic radial stock (isosurface) in Figure 1 that correlates near perfectly with the boundaries of the newly modelled Mo-Cu Porphyry.
Mapped dykes and sills that are considered causative to the project-wide massive sulphide carbonate replacement and skarn mineralization show a perfect correlation to a magnetic isosurface/stock extending below the Pete's CRD Target, and proximal to the untested high chargeability anomaly (120 mV/V) located north of the 2023 drilling area. The dykes at Pete's Target are geochemically related to the Sulphide City Porphyry and may be connected to the rest of the system by narrow dykes that were not picked up by the resolution of the 3D MVI (60m resolution).
Amplitude isosurfaces, representing the overall strength of the magnetic response, correlate well with the proximal CRD and skarn skin surrounding the Sulphide City stock. Remanent magnetism isosurfaces, representing zones with a magnetic field of their own (i.e. different to that of the Earth - usually caused by magnetite or pyrrhotite) also overlie skarn and proximal CRD zones that have been mapped and cut with the drill bit at the Grizzly and Sulphide City targets. The geological model of the Sulphide City Stock, which was built without utilizing the 3D inversion data, and associated dykes correlate extremely well with the radial symmetry inversion data, bolstering the confidence of the team's interpretation of the magnetic inversion dataset. These coincident data will be used by Core Assets geologists for broader targeting across the Blue Property.
A newly discovered feature of note from this data is a radially symmetrical, anomalous, and tubular amplitude feature with a remnant magnetization halo - located approximately 750m to the south of the Gally Target. The southern end of the 2023 3D DC/IP survey covers a portion of this feature and has overlapping high chargeability and high conductivity anomalies. Marble beds with massive sulfide-bearing veinlets (see Figure 1 in News Release dated April 4, 2024) are also mapped overlying the otherwise overburden covered feature. This overlap of multiple features of note is tentatively interpreted as another intrusion related to the system at large with a surrounding massive sulphide skarn-CRD skin.
The 2D structure detection analysis applied to the 2021 VTEM data coincides strongly with mapped faults and dykes at Silver Lime. Mineralized structures and pebble dykes that were mapped and sampled in the Gally area and through the Gally-Sulphide City-Pete's Mineralized Trend over the 2023 field season and were traced for up to 225m along strike, have been traced through the structure detection filters applied by Fathom. Multiple un-sampled structures with similar strike lengths and apparent dips have also been traced via the structure detection analysis. Additional, larger-scale structures with a variety of strikes appear to encircle or bound the main mineralized areas and radially symmetrical isosurfaces at Silver Lime.
The filters and inversions were applied to the portion of the 2021 VTEM survey overlying the 9.5x10 km mineralized footprint of the SLM project, the entire VTEM survey was flown over approximately 15% of the entire Blue Property. The technical team has developed several robust theses based off incorporating the inversions with existing geochemical, structural, and diamond drilling data collected at Silver Lime, which will be tested over the 2024 field season. When additional data gathered over the upcoming season supports the interpretations developed, these targeting criteria will be able to be applied to the remainder of the property to support exploration further afield from the district-scale Silver Lime CRD-Porphyry Project.
THE 2024 EXPLORATION PROGRAM
The team is excited to continue building on several high priority targets for 2024 field season:
- The Sulphide City Cu-Mo Porphyry Target
- High-grade, near surface, structurally controlled CRD and skarn massive sulphide mineralization (Gally, Grizzly, Pete's, and Jackie)
- Vein-Hosted Au+/-Cu+/-Ag (Falcon and Amp)
- High-grade massive sulphide zinc skarn and mineralized porphyry potential (Willison West)
- The newly interpreted porphyry stock south of Gally
Drilling over the 2024 field season will prioritize the deep extension of the Sulphide City Stock - utilizing the mag inversion data, geochemistry, and structural data to guide drilling. The intrusion south of the Gally target will be ground-truthed, and if boots on the ground data is supportive of the current interpretation this new target will be drill tested. Shallow CRD and skarn massive sulphide mineralization will also be opportunistically targeted with the diamond drill.
Figure 5 breaks down the highest priority generative targets for the 2024 field season. Early season ground-truthing and mapping will be conducted at the Willison West Target to follow up on sample 152231, which graded >30% Zn, 0.11 g/t Au, 38.2 g/t Ag, 0.31% Cu 0.09% Pb. The goal of the field work to be conducted at this target is to rapidly generate a new drill target for testing in the 2024 season. Mid- to late-season generative field work will be conducted at the Falcon and Amp targets to better understand the geological and structural controls on mineralization and expand the mineralized footprints of these zones. Grassroots targets (i.e. Willison North) have been identified through various methods and will also be targeted for mapping, prospecting, and initial interpretation using fly camps to reduce costs and provide mapping geologists with increased field time.

EQUIVALENCE CALCULATION
Assay results in this news release are presented as uncut weighted averages and assume 100% metal recovery. Interval widths represent drilled HQ core lengths and true width is unknown currently. Silver equivalent (AgEq) and Copper equivalent (CuEq) grades are calculated using metal prices of silver US$21.25/oz, gold US$1,850/oz, copper US$4.00/lb, lead US$1.00/lb, molybdenum at US$30.00/lb, and zinc US$1.40/lb. Silver equivalent grade is calculated as AgEq (g/t) = Ag (g/t) + (Cu (%) * 129.08) + (Pb (%) * 32.27) + (Zn (%) * 45.18) + (Au (g/t) * 87.06). Copper equivalent grade is calculated as CuEq (%) = Cu (%) + Ag*0.0077) + (Pb (%) * 0.25) + (Zn (%) * 0.35) + (Au (g/t) * 0.674 + (Mo (%) * 7.5). See News Release dated: Dec 14, 2023.
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% ownership in the Blue Property, which covers a land area of114,074 hectares (~1,140 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 and the Carcross/Tagish First Nation. The Blue 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 Blue 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 Blue Property. The past 50 years have seen substantial advancements in the understanding of porphyry, skarn, and carbonate replacement type deposits both globally and in British Columbia'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.
