Core Assets Reports Assay Results From the First Four Drill Holes Completed at the Silver Lime Project, Including 1.25m of 215g/t Ag, 18.8% Zn+Pb, 0.36% Cu & 5.37m of 51g/t Ag, 5.1% Zn+Pb, and 0.19% Cu
VANCOUVER, BC, March 6, 2023 / Core Assets Corp., (“Core Assets” or the “Company“) (CSE:CC) (FSE:5RJ) (OTC.QB:CCOOF) is pleased to announce assay results from the first four diamond drill holes completed at the Jackie CRD Target during the 2022 exploration program at the Silver Lime Porphyry-CRD Project (“Silver Lime”),central Blue Property (“Property”); Atlin Mining District of NW British Columbia.
A total of 1,299 metres of diamond drilling, representing four of fifteen drill holes project wide, were completed at the Jackie CRD Target in 2022. First-pass diamond drilling at the Jackie CRD Target intersected carbonate replacement mineralization near surface and to drilled depths exceeding 200 meters (Figures 1-3).
- SLM22-001 intersected 21.65m of 23g/t Ag, 1.0% Zn, 1.2% Pb, and 0.08% Cu from surface, including 1.25m of 215g/t Ag, 9.9% Zn, 8.9% Pb, and 0.36% Cu.
- SLM22-002 intersected 5.37m of 51g/t Ag, 4.0% Zn, 1.1% Pb, and 0.19% Cu from 1.10m depth, including 1.47m of 140g/t Ag, 6.3% Zn, 3.3% Pb, and 0.10% Cu.
- SLM22-003 intersected 0.93m of 62g/t Ag, 1.6% Zn, and 1.9% Pb from 154.78m depth.
- SLM22-004 intersected 7.90m of 46.7g/t Ag, 0.4% Zn, 0.7% Pb, and 0.19% Cu from 190.70m depth, including 2.00m of 126g/t Ag, 0.8% Zn, 2.0% Pb, and 0.60% Cu, and 0.62m of 338g/t Ag, 2.1% Zn, 5.8% Pb, and 1.55% Cu. (Table 1).
2022 drilling results from the Jackie CRD Target also identified gold grades associated with localized base metal sulphide veining and carbonate replacement mineralization.
- SLM22-004 intersected carbonate replacement mineralization and sulphide-bearing veinlets over 0.53m that returned 0.57g/t Au, 50.4g/t Ag, 1.8% Pb, and 0.4% Zn from 121.82m depth.
- SLM22-004 also intersected 8.00m 0.69g/t Au and 6.5g/t Ag including 2.00m of 5.42g/t Au, and 5.6g/t Ag from 335.00m depth.
- Fugitive calcite was observed in both SLM22-004 Au-bearing intercepts.
Core Assets’ President & CEO Nick Rodway commented: “In our first drill season at the Jackie Target, we have successfully tested the depth extent and mineralization potential of numerous mineralized structures or “spokes” exposed at surface. With a single drill pad, we have demonstrated that there is a high quantity of metal-rich, carbonate replacement mineralization in the subsurface. We are now confident that we can target these host structures down dip, in hopes of intersecting thicker, and continuous massive sulphide feeders in follow-up drill programs. We are also pleased to announce that we have received the remainder of our assay results from the Sulphide City and Grizzly Targets. Our team is working efficiently to compile this newly acquired data in anticipation for release in the coming weeks.”
The highest-grade massive sulphide occurrences at Jackie appear to be associated with steeply dipping, mineralized felsic dykes that crosscut the folded carbonate stratigraphy and have localized massive sulphide mineralization along proximal faults and splays (Figure 2). All surficial structures hosting massive sulphide at Jackie that were targeted during 2022 drilling are confirmed to host high-grade mineralization at depth. It is inferred that these high-grade sulphide occurrences connect to larger massive sulphide feeder zones.A causative intrusion sourcing the mineralized dykes at the Jackie Target has yet to be identified.
Core Assets has also contracted Terrane Geoscience Inc. to conduct a desk-based structural analysis of the Silver Lime Porphyry-CRD Project to assist with drill targeting, and to develop an oriented core protocol in anticipation of the 2023 exploration program. Additionally, assay results for the remaining 11 diamond drill holes (totalling 4,266 meters) completed at the Sulphide City and Grizzly Targets will be released in the coming weeks.
Assay results are presented as uncut weighted averages and assume 100% metal recovery. Interval widths represent drilled HQ core lengths and true width is unknown currently. * indicates partial drill hole assay results were previously released. Silver equivalent (AgEq) 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 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).

Sampling Protocol, Quality Assurance & Quality Control
All recovered drill core was transported by helicopter to the core logging facility in Atlin, BC for processing. Down hole surveys were conducted on all drill holes upon termination, using a Reflex Gyro Sprint downhole survey tool equipped with an azimuth positioning capability. Drill core was typically sampled over two-meter intervals and occasionally reduced in areas of higher visual sulphide mineralization. Core samples were cut in half with an electric core saw, bagged, labelled, sealed, and submitted to ALS Minerals preparation facility in Whitehorse, YT with the remaining core stored in Atlin, BC. Half core samples 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 or ICP-MS finish.
Blank rock (siliceous river rock), duplicate, and certified reference materials were inserted into the sample stream for at least every 20 samples. Certified reference materials were acquired from OREAS North America Inc. of Sudbury, Ontario and CDN Resource Laboratories Ltd. of Langley, British Columbia for the 2022 diamond drill campaign.
A total of 1,299 metres of HQ-sized diamond drilling was completed at the Jackie CRD Target in 2022.
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 dyke proximal 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. 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 surficial grade 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 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 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.
