QC Copper and Gold Inc. announced drill results from its 2024 winter drilling program on the past producing Cooke and Robitaille mines trend. This drill program represents QC Copper's pivot towards resource expansion beyond what was published in Mineral Resource Estimate of January 8, 2024 when is defined Canada's Highest Grade Open Pit Copper Deposit. This drill program tested the extension between Cooke and Robitaille and identified mineralization
continuity between the two past-producing mines. The results from the four holes indicate that Cooke and Robitaille may be connected, and they show similar high-grade and long intersections to those seen at the Springer and Perry zones. These results suggest that there is potential for significant growth outside of the current Opemiska pit that could be contemplated for future economic studies. The Cooke-Robitaille trend is the most promising area for adding mineral resources to the Opemiska Project in the near term. These two past producing mines have seen significant historical drilling, approximately 5,000 drill holes, mainly from Falconbridge, the past operator of the mines. A detailed compilation of these historical drill holes is underway to identify additional areas of interest to target at the Cooke-Robitaille trend. Subsequently, the Company will announce a systematic drill campaign to deliniate mineral resources at Cooke-Robitaille. Additionally, mineral resources are expected to be added on the Eastern Veins near the conceptual pit, which has seen extensive drilling by QC Copper but requires geological modelling to define some in-pit mineral resources. The technical information contained in this news release has been reviewed and approved by Charles Beaudry, P.Geo and géo., Director and Vice President Exploration for QC Copper & Gold, a Qualified
Person, as defined in "National Instrument 43-101, Standards of Disclosure for Mineral Projects." For the exploration undertaken by QC Copper & Gold, all assay batches are accompanied by rigorous Quality Assurance procedures, including the insertion of standards and blanks and verification assays in a secondary laboratory. All the core received from the drill is split in half, bagged and sent to ALS-Global facilities in Quevillon, Quebec for sample preparation and then the pulps are shipped to AlS-Global's Vancouver laboratory or some other location in the world for analysis using ALS-Global's standardized ISO-compliant methods, all of which are listed in the laboratory certificates provided with the assay results. The remaining half core along with the rejects and the pulps returned from the laboratory are securely stored at QC Copper's facilities in Chapais, Quebec. Quality Control results, including the laboratory's control samples, are evaluated immediately on reception of batch results and corrections are implemented immediately if necessary. All drill collars are surveyed and positioned in UTM coordinates. Collars are oriented using a gyroscopic north-finding system and downhole deviations surveys are done with a single-shot gyroscopic instrument at 30 to 50m intervals. For veins oriented approximately northwest-southeast and dipping vertically, and drill holes oriented southwest and plunging between 50 and 65 dips, the true width of mineralized intersections are equal or greater than 70% of the quoted core length composite intervals.
