Dore Copper Mining Corp. completed two drill holes totaling 1,392 meters which successfully extended the Southwest Zone of the former Cedar Bay copper-gold mine located in the Chibougamau mining camp, approximately 5 kilometers by road from its Copper Rand mill.

The Southwest Zone is located 300 meters to the southwest of the Cedar Bay mine Main Zone and was partially developed in late 1960s by Campbell Chibougamau Mines Limited on two levels  right to the property limit with Patino Mining. The best results of Campbell’s drilling campaign in the Southwest Zone included 5.2 meters of 2.56% Cu and 3.9 meters of 2.22% Cu and 1.3 g/t Au1. The potential extension of the Cedar Bay Southwest Zone along strike to the southeast was never tested by Patino Mining and subsequent companies that controlled that ground. In total, approximately 1,080 meters of strike length had not been tested up to the Lac Dore Fault.

Copper mineralization was intersected at a vertical depth of 541 meters with 0.40 meter of 1.70% Cu and 2.03 g/t Au, characterized by chalcopyrite disseminations and blebs in a discontinuous massive iron oxide band. The strong alteration footprint intersected in hole CDR-24-10 in the anorthosite to gabbroic rocks is characteristic of the Dore Lake Complex magmatic-hydrothermal system and is interpreted to be an indicator of proximity to mineralized ore bodies of the Cu-Au central mining camp.

The Company plans to conduct downhole geophysics to locate stronger conductors near and along the structure as the first hole may not have crossed it. The strong alteration footprint intersected in the second hole is promising as it indicates approximately 400 meters of strike length untested towards the Doré Lake Fault.

Dore Copper received a grant from the Government of Québec of approximately C$182,000 towards the drilling program and geometallurgical characterization. The grant has been offered under the Mineral Exploration Support Program for Critical and Strategic Minerals (Programme de soutien à l’exploration minière pour les minéraux critiques et stratégiques 2021-2024 or PSEM-MCS), which is overseen by the Ministry of Natural Resources and Forests (Ministère des Ressources naturelles et des Forêts or MRNF).

Cedar Bay Mine:

The Cedar Bay mine operated from 1958 to 1990 and produced 3.9 million tonnes grading 1.56% Cu and 3.22 g/t Au2. The ore from the mine was processed at the Copper Rand mill located 5 kilometers by road. The deposit was mined to a depth of 670.5 meters and the existing shaft extends to a depth of 1,036 meters.

About Dore Copper Mining Corp.

Dore Copper Mining Corp. aims to be the next copper producer in Québec with an initial production target of +50 Mlbs of copper equivalent annually by implementing a hub-and-spoke operation model with multiple high-grade copper-gold assets feeding its centralized Copper Rand mill3. The Company has delivered its PEA in May 2022 and is proceeding with a feasibility study.

The Company has consolidated a large land package in the prolific Lac Dore/Chibougamau and Joe Mann mining camps that has historically produced 1.6 billion pounds of copper and 4.4 million ounces of gold2. The land package includes 13 former producing mines, deposits and resource target areas within a 60-kilometre radius of the Company's Copper Rand Mill.
