CANADIAN COPPER ANNOUNCES NEW MINERAL RESOURCE ESTIMATE AT MURRAY BROOK: +21 MILLION TONNES CONTAINING +670 MILLION IN-SITU POUNDS COPPER EQUIVALENT

Canadian Copper Inc. has released a new mineral resource estimate (MRE) for the Murray Brook project located in New Brunswick, Canada.

"The pending 100-per-cent acquisition of an advanced-stage, large and high-quality base metal deposit in a safe jurisdiction is rare. Murray Brook has several key attributes: the deposit topography is conducive to surface development, its sulphide mineral resource is more than 98 per cent M&I [measured and indicated], with an NSR [net smelter return] value of $115/tonne mineralized material. With an open-pit mineral resource of more than 21 million tonnes and situated less than 10 kilometres from a fully operational process plant, this deposit could be supplying the critical minerals Canada needs much faster than most domestic development projects," said Simon Quick, chief executive officer of Canadian Copper.

Sulphide mineral resource estimate highlights:

• Measured: 15.8 million tonnes (Mt) grading 2.60 per cent Zn (zinc), 0.43 per cent Cu (copper), 0.92 per cent Pb (lead), 0.52 gram per tonne (g/t) Au (gold) and 39 g/t Ag (silver) (1.42 per cent CuEq (copper equivalent) or 8.65 per cent ZnEq (zinc equivalent)).
• Indicated: 5.3 million tonnes grading of 2.14 per cent Zn, 0.52 per cent Cu, 0.85 per cent Pb, 0.67 g/t Au and 37.3 g/t Ag (1.41 per cent CuEq or 8.58 per cent ZnEq).

Next steps for the Murray Brook project:

• The company has designed a 12-hole, 3,000-metre drill program to determine the extent of a new copper and gold zone (MB19-01: 1.35 per cent Cu, 19 g/t Ag and 0.18 g/t Au over 26 metres) defined by 12 of the 2017 to 2019 drill holes, which are an approximate 50-metre stepout to previous drilling.
• Review process options to potentially recover the 400,000-gold-ounce mineral resource that exists within the oxide and sulphide MRE. Presently, 0-per-cent recovery is attributed for gold.
• Initiate an updated preliminary economic assessment (PEA) to include several critical trade-off studies. For example, the open-pit Murray Brook deposit is high grade (1.42 per cent CuEq or 8.65 per cent ZnEq) and conducive to low capital cost toll processing within the Bathurst region. A toll milling development scenario will improve permitting timelines and reduce project execution risk.
• Commence regional exploration across the 18 km Caribou Horizon corridor that remains highly prospective, and has produced greater than 700 million pounds of zinc plus copper, lead, silver and gold since the 1970s.

This MRE for Murray Brook is based on data with an effective date of Sept. 27, 2023.

Geologic model

The Murray Brook sulphide mineralization is classified as a sedimentary rock-hosted volcanogenic massive sulphide (VMS) deposit. This type of deposit is characterized by massive to semi-massive iron sulphide minerals that contain variable amounts of base metals and precious metals, and is well studied and documented. Genetically, these deposits are coeval with felsic volcanic centres, and are generally lens-like and stratabound, with a discordant hydrothermal pipe at the stratigraphic base of the sulphide accumulation.

Resource estimate methodology

The drilling database for the Murray Brook project contains 12,900 samples, all of which were analyzed for copper, lead, zinc, gold and silver. A total of 10,200 assays from 187 drill holes have been utilized for the mineral resource estimate. One hundred fifty-nine drill holes were completed between 2011 to 2013.

Grade capping was investigated on the one-metre composite values within the constraining domains to ensure that the possible influence of erratic high values did not bias the database. Based on the log-normal histogram performance, Pb was capped at 16 per cent, Zn at 24 per cent and Ag at 410 g/t, whereas no capping was applied for Cu and Au.

The Murray Brook mineral resource block model was constructed using Gemcom modelling software. The block model is oriented with X-axis at 110 degrees azimuth with three m by three m by three m blocks. Inverse distance squared grade interpolation was utilized for the Cu, Pb and Zn grade interpolation, whereas inverse distance cubed was used for the Au and Ag grade interpolation, both with the capped composites. The average block-model mineralized bulk density was calculated to be 4.24 tonnes per cubic metre.

The mineral resource classification was determined with Zn interpolation, due to Zn generating the highest proportionate NSR value in the block model. Based on the semi-variogram performance and density of the drilling data, the measured resource classification was justified for blocks interpolated by the first pass using at least seven composites from a minimum of four drill holes within a spacing of 25 m along strike, 40 m down dip and 15 m on the across-dip direction. Indicated mineral resources were classified to the blocks interpolated with the second pass and inferred mineral resources were classified for all remaining blocks.

Sensitivity analysis

A sensitivity analysis is presented in the table entitled "Pit-constrained sulphide mineral resource estimate sensitivity" to help conceptualize grade and tonnage estimates at various NSR cut-off value increments for the Murray Brook deposit.

Quality assurance/quality control

Drill core were sawn in half using a using a VanCon diamond saw for 2010 to 2013 drilling and a hydraulic core saw for all 2017 to 2019 drilling. All samples were weighed by a company technician, with certain samples weighed both in air and water to measure bulk density. One-half of the drill core was placed in a standard plastic sample bag and the other half carefully returned to the core box for reference. Samples were picked up from the drill core facility by bonded courier and driven to TSL Laboratories in Saskatoon throughout the 2010 to 2013 drill programs. Samples taken during the 2017 to 2019 drill programs were picked up at the core facility by courier and transported to the ALS Global facility in Sudbury for sample preparation, before being shipped to the ALS Global laboratory in Vancouver for geochemical assaying.

Samples at TSL were crushed to 70 per cent passing minus-10 mesh (1.70 millimetres (mm)), from which a 1,000-gram (g) portion is riffle split and pulverized to 95 per cent passing minus-150 mesh (106 micrometres). Samples at ALS Global were crushed to 70 per cent less than two mm, from which a 250-gram portion was riffle split and pulverized to better than 85 per cent passing 75 micrometres. Samples at TSL and ALS were assayed for Cu, Pb, Zn and Ag using a four-acid total digestion with AAS (atomic absorption spectroscopy) finish (TSL) or ultratrace aqua regia followed by ICP-MS (inductively coupled plasma mass spectrometry) (ALS). Gold was determined by a standard lead collection fire assay procedure using a 30-gram aliquot with an AAS finish, with overlimit samples reanalyzed by fire assay with gravimetric finish. Quality control procedures included the routine insertion of prepared certified reference materials and sourced blank material. QA/QC field duplicates have been routinely assayed.

Data verification

The authors validated the post-2010 assays in the database against independently acquired analysis certificates from the laboratories that conducted the assaying. Additionally, the authors collected independent due diligence samples on the site visit and verified them against the database. The authors are of the opinion that the data in the Murray Brook database are suitable for mineral resource estimation.
