"Total" represents the length weighted average of the sum of all samples collected over the 8m long channel at Pete's CRD Target. True widths are currently unknown.
High-grade massive sulphide in the form of carbonate replacement mineralization at Pete's is hosted in limestone near NW-SE trending lithological contacts with biotite schist and is observed intermittently for over 300m (Table 1, Figures 1-2). This new Target is located along trend with the limestone units at the high-grade Grizzly CRD Target and the Amp Target - which is host to both massive sulphide carbonate replacement and base metal sulphide veins with exceptional silver, lead, and zinc grades and local copper and gold. In each Target area, high-grade mineralization is currently observed near predominantly NNE-SSW trending faults and associated splays that have caused minor displacement of the folded stratigraphy. In 2022, during project-wide prospecting and reconnaissance sampling, sulphide-bearing vein samples collected from the Amp Target graded up to 474g/t Ag, 13.7% Pb, 7.6 % Zn, and 0.37g/t Au (Figure 1). Combined, these three Target areas currently boast an average surficial grade of 143g/t Ag, 3.0% Pb, 5.8% Zn, 0.28% Cu, and 0.15g/t Au over 117 surficial samples, defining a 1.57 KM2 zone of carbonate replacement mineralization located within the 6.6 x 1.8 KM mineralized project area.
"The Silver Lime Porphyry-CRD Project continues to produce exceptional metal grades along surface and at depth" said Core Assets' President & CEO, Nick Rodway. "In addition to first-pass diamond drilling, in 2022 our team also completed ground reconnaissance which led to the discovery and extension of the Pete's CRD Target. Pete's Target is interpreted as numerous chimney-style massive sulphide bodies that are along trend with the Grizzly CRD and Amp targets; and, are located more than a kilometer away from the exposed Sulphide City Porphyry. We are currently integrating all geological data as it becomes available and the Core Assets team is eagerly awaiting drilling assay results as we continue to prepare for an aggressive, CRD focused diamond drilling campaign in 2023."

2022 Silver Lime Project Drill Results Update
Core Assets completed 5,355 metres of diamond drilling over 15 HQ-sized holes at the Silver Lime Porphyry-CRD Project in 2022. In October of 2022, the Company reported rushed assay results for select intervals from two drill holes (SLM22-001 and SLM22-011) that contained classic carbonate replacement massive sulphide mineralization, confirming that surface mineralization continues and gets stronger with depth. SLM22-011 (Grizzly CRD Target) returned 1.97m grading 661g/t Ag, 13.2% Zn, 14.0% Pb, 0.27% Cu, and 0.22g/t Au including 1.16m of 1,145g/t Ag, 23.5% Zn, 23.2% Pb, 0.52% Cu, 0.37g/t Au, whereas SLM22-001 (Jackie CRD Target) returned 17.19m of 28g/t Ag, 1.2% Zn, 1.4% Pb, and 0.10% Cu including 1.25m of 215g/t Ag, 9.9% Zn, 8.9% Pb, and 0.36% Cu.
The Company expects to report the full assay results for SLM22-011 and SLM22-001 and the remaining drill holes completed at the Silver Lime Porphyry-CRD Project as soon as they become available.

QA/QC and Sample Preparation
All channel samples were cut in the field using a gas-powered diamond blade rock saw. Locations were marked with spray paint across presumed mineralized horizons and parallel lines were cut approximately 5 centimetres apart. Perpendicular lines were then cut at approximately 1-metre sample intervals. 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.
All rock samples were shipped by ground to ALS Preparation Facility in Whitehorse, YT where they were finely crushed and sieved to <75 microns. Samples were then shipped to ALS Geochemistry in North Vancouver, BC where they were analysed for gold by fire assay with an AA finish, over limits for Ag, Pb Cu and Zn and additional elements were analysed using four acid digestion with an ICP-AES finish.
About the Silver Lime Porphyry-CRD Project
The Silver Lime Porphyry-CRD Project is predominantly hosted in carbonate rocks of the Florence Range Metamorphic Suite (ca. 1150Ma). Target limestone and marble host rocks are intercalated with upper amphibolite grade metapeltic rocks, quartzite, and amphibole-bearing gneiss. The protoliths to the metasedimentary units include continentally derived clastic strata and platform carbonate, whereas the amphibole-bearing gneiss is interpreted as probable basaltic flows, sills, dykes, and tuffaceous units related to early rifting of the ancestral North America continental margin (i.e., Mihalynuk, 1999). Younger felsic to intermediate intrusive rocks are also widespread within the project area and range from Triassic to Eocene in age. Widespread Eocene magmatic activity was associated with Cordillera-wide, brittle strike-slip faulting. Eocene volcano-plutonic centres in the western Cordillera are known to host porphyry, skarn, and epithermal-type mineralization extending from the Golden Triangle in NW BC to the Tally-Ho Shear Zone in the Yukon (>100 kilometers).
Three well-defined target areas exist at the Silver Lime Porphyry-CRD Project and include the Jackie, Sulphide City, and Grizzly targets. The Jackie Target represents a distal expression of Ag-Pb-Zn-Cu CRM that consists of numerous massive-to-semi massive sulphide occurrences measuring up to 30 metres long and 6 metres wide and 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 in multiple directions. Many sulphide occurrences at Jackie are clustered and hosted within NE-SW trending faults and fault splays, proximal to undeformed felsic dykes oriented sub-parallel to faulting. These fault-hosted sulphide bodies are interpreted as "spokes" that typically broaden at depth and express continuity back towards a causative intrusion. The Sulphide City Porphyry-Skarn Target is characterized by multiple semi-massive to massive sulphide occurrences measuring up to 40 metres along strike and 8 metres wide. In 2022, detailed geological mapping and diamond drilling discovered a Mo-Cu-bearing and causative porphyry intrusion. The Sulphide City Target boasts an average surficial grade of 13.3g/t Ag, 0.34% Cu, and 3.9% Zn (83 rock samples) that remains open. The Grizzly Ag-Zn-Pb-Cu-Au CRD Target represents the largest, untested surficial exposure of CRM globally. Carbonate replacement manto, chimney, and dyke-contact skarn mineralization at Grizzly are observable at surface across open strike lengths of up to 1 kilometer, and at widths of over 5 meters. Average surficial grade at the Upper Grizzly CRD Target yields values of 164.7g/t Ag, 0.42% Cu, 3.8% Pb, and 7.1% Zn over 450m strike length, whereas the Lower Grizzly Manto has an average graded of 70. g/t Ag, 0.36% Cu, 0.2% Pb, and 7.1% Zn over an inferred strike length of 1km.

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 of111,747.96 ha (~1,117 km²). The Property 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 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.
