Toronto, Ontario – May 3, 2023 – Doré Copper Mining Corp. (the “Corporation” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) is pleased to announce its plans to drill several high priority copper-gold targets in the Central Chibougamau mining camp, located in proximity to its existing Copper Rand mill, near Chibougamau, Québec (Figure 1). The drilling program is scheduled to start at the end of June.
High Priority Drilling Targets:
Jaculet (Figure 2)
The Jaculet mine, located 2.5 kilometers by road from the Copper Rand mill, was in operation from 1960 to 1971 and produced a total of 1,091,000 tonnes at 1.84% Cu, 1.44 g/t Au and 6.85 g/t Ag (20,074 tonnes of Cu and 1.57 tonnes Au)1. Jaculet was mined to a depth of 366 meters (1,200 feet) and the shaft was deepened to 500 meters (1,650 feet) in 1972. The Jaculet mineralized system consists of two distinct shear zones, known as Zone 1 and Zone 2, which both remain open at depth with very little development below 366 meters.
Two surface holes completed in 1956 by Chibougamau Jaculet Mines Ltd. intersected Zone 1 at a vertical depth of approximately 400 meters. Hole V17 and V17A (wedge from V17, located approximately 50 meters to the east) intersected 4.55% Cu and 0.86 g/t Au over 6.7 meters and 4.25% Cu and 0.59 g/t Au over 6.4 meters, respectively.
Doré Copper plans to drill two holes for a total of 1,300 meters. The first hole will test the potential down plunge extension of holes V17 and V17A in Zone 1. The second hole will test another potential ore shoot located approximately 400 meters to the west.
The Jaculet deposit is defined by two distinct subparallel shear zones, known as Zone 1 and Zone 2, separated by approximately 200 meters, where the veins within both zones typically range from 91 to 137 meters in strike length. Zone 1 extends for approximately 500 meters and has an average strike of 290° with a northerly dip ranging from 55° to near vertical. Mineralization in Zone 1 consists of chalcopyrite and minor pyrite within the sheared and altered gabbroic anorthosite. Zone 2 extends for approximately 670 meters in length and is oriented at 80° north dipping 80-85° to the south. Mineralization consists of stringers of pyrite with erratic lenses of chalcopyrite associated with siderite, sericite and chloritoid.
Cedar Bay Southwest Zone Extension (Figure 3)
The Southwest Zone, located 300 meters southwest of the Cedar Bay Main Zone, was partially developed by Campbell Chibougamau Mines Limited up to the 200-meter (650-feet) level, right at the property limit with Patino Mining. 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 800 meters of strike length have not been tested up to the Lac Doré Fault.
Doré Copper plans to drill two holes from the same pad for a total of 1,500 meters to test the potential southeast extension of the Cedar Bay Southwest Zone.
The Cedar Bay mine operated from 1958 to 1990 and produced 3.9 million tonnes grading 1.56% Cu and 3.22 g/t Au1. 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. Doré Copper, while private, completed four holes (including wedges) totaling 4,842 meters in 2018 and reported an Indicated resource of 130,000 tonnes at 9.44 g/t Au and 1.55% Cu, and an Inferred resource of 230,000 tonnes at 8.32 g/t Au and 2.13% Cu (effective date of December 31, 2018)2. During 2020, the Corporation completed 9,025 meters of drilling and successfully extended a number of mineralized lenses (the 10-20A and 10-20B).

Toronto, Ontario – April 18, 2023 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) is pleased to announce positive results from ore sorting test work for its flagship Corner Bay high-grade copper-gold project located approximately 55 kilometers by road from the Corporation’s Copper Rand mill, near Chibougamau, Québec.
Steinert was commissioned to complete ore sorting tests at their facility in Kentucky, United States, using a XRT sensor (X-ray transmission) and a laser sensor on a spatially diverse sample from the Corner Bay deposit.
The results support the first ore sorting test work that was completed for the preliminary economic assessment (“PEA”) and further confirm the effectiveness of utilizing ore sorting technology to improve the processed grade and reduce the mill feed tonnage.
Highlights of Ore Sorting Test
Copper grade increase of77%, from 2.20% to 3.93%
Recovery of 93.6% Cu
Reject material contains 48% of the initial mass with a copper grade of 0.30%
Gold, silver and molybdenum grade also upgraded with excellent recoveries and low concentration in reject
Cost and environmental benefits include:
Lower transportation costs and greenhouse gas emissions (GHGs) due to a reduction of transported material from the mine to the mill
Lower energy consumption at the mill due to higher feed grade and hardness decrease of the feed material
Less tailings produced
Additional capacity of the mill to treat additional materials
Waste material at the mine site (reject material) to be used as backfill
Commenting on the results of our second ore sorting tests, Ernest Mast, President & CEO, stated, “This test work further validates the favorable mineralogy of the Corner Bay deposit for ore sorting technology and confirms the prior ore sorting results obtained from the Corner Bay stockpile, which were included in the PEA. Preliminary ore sorting test work at Devlin in 2022, our secondary hub-and-spoke asset, had also indicated positive results. Ore sorting of the Corner Bay and Devlin will remain part of any future development scenarios due to its economic and sustainability benefits.
Ore Sorting Tests
As a first step, the Steinert XRT was calibrated with high, medium and low grade and waste samples representative of the selected drill core samples of the Corner Bay deposit (Figure 1). A continuous production run was done on the 202 kg sample. The testing was done with three passes with the explicit aim of generating grade vs recovery vs mass pull curves, with each pass related to an adjustment in the sensitivity. Results are shown in the table below.
The sum of the two pre-concentrates (Test 2 in table below) represented 52.5% of the feed mass at a grade of 3.93% Cu (an increase of 77%) and resulted in a cumulative copper recovery of 93.6%. The final reject portion represented 47.5% of the feed mass at a grade of 0.30% Cu, representing 6.4% of the copper fed in the sorter. In addition, all other metals to be recovered (gold, silver and molybdenum) showed an upgrade in grade:
Gold grade: from 0.17 g/t to 0.29 g/t
Silver grade: from 7.91 g/t to 13.82 g/t
Molybdenum grade: from 0.037% to 0.064%
Lastly, the arsenic grade of the two pre-concentrates was found to be 12ppm which leads to a final concentrate with very low levels of arsenic.
Minimal fines were generated in the test work and were not considered for calculations. In practice, the fine material from the mining and crushing would join the pre-concentrate in the ore sorting circuit and would result in a higher recovery than indicated in the test work. In addition, as the sorter can be calibrated to control the final reject grade, a higher copper feed grade would result in higher recoveries.

Corner Bay Composite Sample
A spatially diverse composite sample was prepared by Doré Copper by selecting 34 diamond drill holes which intersected mineralized zones within the Corner Bay Mineral Resource estimate (“MRE”) (Figure 1; one mineralized sample was outside the current MRE). The core material selected represented different rock types: semi and massive sulphides, quartz veins, diorite dyke, and fresh and altered anorthosite. The drill core was sampled by cutting a quarter split NQ core. The longer pieces of quarter split core were further manually broken down into 1 to 3 inches length to simulate a crushed product. The composite sample weighted 202 kg and graded 2.20% Cu (Test 4 in table above) and included an 18% external mining dilution from the hanging wall and foot wall of the mineralized interval.
The PEA did not include the silver and molybdenum content (currently excluded from the MRE). The composite sample indicated silver and molybdenum grades that would be expected in the deposit (Test 4 in table above).
Substantial Benefits of Ore Sorting
As already indicated in the Company’s PEA (May 10, 2022), ore sorting technology offers substantial benefits versus conventional processing. It will reduce operating costs for milling, flotation and tailings management due to a significant rejection of low-grade material. Sorting is expected to decrease the hardness of the ore sent to the mill (lower Bond Work Index of the sorter pre-concentrate product compared to the feed), and so, non-negligeable energy savings could be foreseen. The commensurate increase in the head grade of the ore that will report to the flotation circuit has the potential to result in improved metallurgical recoveries in the flotation circuit and higher concentrate grades.
Further metallurgical and environmental testing, including comminution, flotation and leachability testing, will be carried out to progress the feasibility study and ongoing permitting.

Toronto, Ontario – March 2, 2023 – Doré Copper Mining Corp. (the “Corporation” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) is pleased to announce the discovery of a new copper-gold mineralized zone at the Doré Ramp copper-gold deposit located 2.5 kilometers from the existing Copper Rand mill, near Chibougamau, Québec. To date, the Company has completed six holes, including two wedge cuts, for a total of 7,020 meters. Assays have been received for the first three holes (Table 1).
This new copper-gold mineralized zone was intersected in all six holes over a strike length of approximately 360 meters (Figure 1). It is located approximately 300 meters to the south of the Doré Ramp zone with parallel strike and dipping approximately 55° to the southwest as per current interpretation. The new zone is characterized by a 2 to 8 meter zone of quartz veining containing localized disseminated and/or massive chalcopyrite and pyrite within a large ductile fault zone that is strongly sericitized and chloritized. The first three holes drilling intersections include:
LDR-22-01W2: 3.98% Cu and 0.36 g/t Au over 2.35 meters, including 16.45% Cu and 0.7 g/t Au over 0.35 meter (Figure 2)
LDR-22-01W1: 2.34% Cu and 0.97 g/t Au over 1.8 meters, including 3.01% Cu and 1.24 g/t Au over 1.4 meters
LDR-22-01: 0.58% Cu and 0.65 g/t Au over 0.4 meter
Holes LDR-22-03 and 04 (assays pending) intersected chalcopyrite and pyrite mineralization in the new zone.
This drilling program was initially designed to test the continuity of the Doré Ramp copper-gold mineralized zone at depth. Hole LDR-22-01, at a vertical depth of approximately 900 meters, returned 4.37% Cu, 0.87 g/t Au and 13.0 g/t Ag over 2.4 meters, including 17.6% Cu, 1.76 g/t Au and 43.9 g/t Ag over 0.5 meters (news release September 12, 2022). Hole LDR-22-01W1 intersected the Doré Ramp zone approximately 50 meters west and below the above-mentioned intercept with 0.60% Cu and 2.85 g/t Au over 1.6 meters, including 1.61% Cu and 7.57 g/t Au over 0.6 meter. Hole LDR-22-01W2, located 40 meters west and above intercept in LDR-22-01, did not intersect any signification mineralization on the Doré Ramp zone.
The latest hole completed LDR-23-04 (assay pending) is the first hole to intersect the Doré Ramp zone in multiple parallel mineralized zones containing chalcopyrite and pyrite starting at a vertical depth of 800 metres (Figure 3). The Company plans to continue its exploration drilling program at Doré Ramp and other targets on the property.
Ernest Mast, President and CEO of Doré Copper, stated, “The discovery of a new mineralized zone at Doré Ramp, in addition to our exploration drilling which has extended the Doré Ramp zone at depth, confirms the Company’s exploration model of additional copper-gold zones on the east side of the Lac Doré fault, in the vicinity of the Doré Ramp and Copper Rand deposits. These encouraging results to date, in close proximity to the Copper Rand mill, support additional exploration drilling to potentially enhance our hub-and-spoke operation model for the Chibougamau mining camp.”
Doré Ramp Deposit
The Doré Ramp deposit is within the Chibougamau Central mining camp and as many other deposits and mineral occurrences it is within a wide shear zone of 100 to 400 meters perpendicular to the Lac Doré fault. In the Chibougamau Central camp, the copper and gold-rich mineralized zones are in contact with acidic to intermediate dykes interpreted as originating from the Chibougamau Pluton. The Doré Ramp deposit starts at 80 meters below surface and has been tested over a strike length of approximately 500 metres. It consists of a series of subparallel pinch and swell veins, varying in thickness from 0.3 to 7.7 meters, over a strike length of up to 300 meters. A number of mineralized lenses are displaced by northeast faults at 15 to 30 metres intervals.
The Doré Ramp deposit was drilled in a few different phases from 1984 to 1992. A total of 47 drill holes from surface are reported during that period. A double ramp approximately 1 kilometer long was excavated in 1991-92 to a vertical depth of 160 metres, followed by an underground drilling campaign of 46 holes totaling 10,200 metres testing the deposit to a depth of 240 meters. Only five holes tested the deposit between 300 and 600 meters. At the end of 1992, Westminer Canada reported a historical estimate of 209,120 tonnes at 1.23% Cu and 5.4 g/t Au, from a depth of the surface pillar of 115 meters to 350 meters (Source: Westminer Canada Limitée, Project Lac Dore, November 1992). This estimate is considered to be historical in nature and should not be relied upon. A Qualified Person has not completed sufficient work to classify the historical estimate as a current mineral resource or mineral reserve. The Company is not treating the historical estimate as current mineral resources or mineral reserves). No subsequent exploration programs were carried out on the Doré Ramp deposit.
Other Exploration Targets in Central Chibougamau Camp
Doré Copper continues its compilation work on the area around the large Copper Rand property in the Central Chibougamau Camp and intends to follow up on a number of exploration targets in 2023. The Doré Ramp North Zone and Copper Rand South targets have not been tested below depths of 500 meters (Figure 3).
Doré Ramp North Zone
The Doré Ramp North Zone is located 450 meters northeast of the Doré Ramp deposit (and approximately 2 kilometers southwest from Copper Rand mine and mill) and is defined by a shear corridor parallel to the Doré Ramp shear. Information collected from 11 historical drill holes targeting the Doré Ramp North show similar mineralization to the Doré Ramp. The best intersections reported were 2.13% Cu and 1.25 g/t Au over 2.3 metres (hole S4-91-6) and 1.43% Cu and 1.68 g/t Au over 2.75 metres (hole S4-91-9) (Source: Westminer Canada Limited, drill logs March 1991).
Copper Rand South
Copper Rand South (also known as Kerr Addison) is another shear corridor parallel to the Copper Rand shear located 490 meters to the southwest. The shear is approximately 60 meters wide and hosts a number of mineralized veins with chalcopyrite, pyrrhotite, sphalerite, and pyrite. A portion of the deposit was mined as part of the Copper Rand mine between the 230 and 400 meter levels (e.g., veins 60-1, 57-3 and 65-5). Reported mined grades range from 1.20% Cu and 3.6 g/t Au from 230 to 300 meters, and 1.76% Cu and 0.93 g/t Au from 300 to 400 meters.
There is an area of approximately 450 meters in strike length that has not been explored towards the Lac Doré Fault. Geophysical surveys from 1991 indicate a conductive zone of approximately 100 square meters in that area. Copper Rand South remains open below 400 meters.

CB-22-86: 5.1 meters of 5.68% Cu, 0.32 g/t Au, 18.3 g/t Ag, and 510 ppm Mo
CB-22-83: 2.6 meters of 3.69% Cu, 10.3 g/t Ag, and 414 ppm Mo
Main Vein above dyke
CB-22-96: 3.3 meters of 2.53% Cu, 0.40 g/t Au and 2.1 meters of 4.73% Cu, 0.23 g/t Au, 45.5 g/t Ag, and 401 ppm Mo
Ernest Mast, President and CEO of Doré Copper, commented, “We have completed nearly 40,000 meters of drilling at Corner Bay in 2022, mostly infill drilling required for the feasibility study. Overall, the results confirm the continuity of the copper mineralization in the deposit. We have also identified a number of holes from 2004 with high-grade copper mineralization in the upper portion of the deposit that were not incorporated in the mineral resource. It is our intention to continue the Corner Bay infill drilling program in 2023 following the exploration drilling at the Doré Ramp and Joe Mann as detailed in the September 12, 2022 news release. Subject to improved market conditions and additional funding, we now expect to complete the feasibility study in 2024.”
Corner Bay Drilling Program
The drilling program which started in early 2022 is designed to infill the Corner Bay deposit at a 50 to 60 meter spacing from surface to a depth of 1,000 meters. From today’s results, 9 holes intersected the Main Vein above the dyke and the remaining 3 holes intersected the Main Vein below the dyke. The results are continuing to confirm the continuity of the copper mineralization for the Main Vein above and below the dyke (Figure 1 and Table 1).
The results today have defined the presence and continuity of a second vein located 50 meters east of the Main Vein above the dyke (Figure 2). This second vein has been intersected by six drill holes to date (CB-21-53, 58, 60 and CB-22-96, 97 and 98) and remains open up-dip. Mineralization in this area appears to be parallel and controlled by mafic dykes, interpreted as originating from the Chibougamau Pluton. Hole CB-21-53 intersected 2.0 meters of 3.34% Cu, 0.56 g/t Au, and 15.6 g/t Ag (February 8, 2022 news release), hole CB-21-58 intersected 0.6 meter of 0.9% Cu, and hole CB-21-60 intersected 1.6 meters of 1.27% Cu.
Following a review of the required drilling for the feasibility study, the Company has identified nine (9) holes from 2004 that were excluded from the current mineral resource estimate (see Figure 1 and Table 2). All holes intersected copper mineralization at a shallow depth in the two subparallel veins (Main Veins) above the dyke. Significant high-grade intercepts included:
CB-04-13: 7.07 meters of 10.09% Cu, 0.61 g/t Au
CB-04-15: 13.0 meters of 3.23% Cu, 0.38 g/t Au
CB-04-17: 13.25 meters of 8.52% Cu, 0.51 g/t Au
Corner Bay Deposit
In the Preliminary Economic Assessment announced on May 10, 2022, the Mineral Resource estimate (“MRE”) for Corner Bay contains an Indicated Resource of 2.68 Mt at 2.66% Cu and 0.26 g/t Au containing 157 million pounds of copper and 22,000 ounces of gold and an Inferred Resource of 5.86 Mt at 3.43% Cu and 0.27 g/t Au containing 443 million pounds of copper and 51,000 ounces of gold, based on a cut-off grade of 1.3% Cu and a copper price of US$3.75 per pound (refer to Technical Report dated June 15, 2022)1. The Corner Bay deposit contains significant silver and molybdenum which have not been included in the prior MREs. The feasibility study will include the addition of silver and molybdenum as by-products.
The Corner Bay deposit is hosted by the intrusive Lac Doré Complex on the southern flank of the Chibougamau anticline. A regional north-northeastern diorite dyke also cuts the area. Several significant shear zones oriented north-south and northwest-southeast have been identified in the area. The Corner Bay area is characterized by copper porphyry style mineralization and by copper mineralization in shear zones commonly associated with dykes related to the Chibougamau Pluton.

Drilling and Quality Control
The Company is using Miikan Drilling as the drilling contractor. Miikan is a joint venture between Chibougamau Diamond Drilling Ltd., the First Nations community of Ouje-Bougoumou and the First Nations community of Mistissini both located in the Eeyou Istchee territory.
Sample preparation and analysis within the mineralized zones are completed at AGAT Laboratories in Mississauga, Ontario. For AGAT, samples are weighed, dried, crushed to 75% passing 2 mm, split to 250 g, and pulverized to 85% passing 75 microns. Samples are then fire assayed for Au (50 g) and 4 acid digest ICP-OES finish for 43 elements. Outside the mineralized zones, sample preparation is completed at SGS Canada Inc. in Val-d’Or, Québec and analysis (fire assay and ICP analysis) is completed at SGS Canada Inc. in Burnaby, B.C. Samples are weighed, dried, crushed to 75% passing 2 mm, split to 250 g, and pulverized to 85% passing 75 microns. Samples are then fire assayed for Au (50 g) and sodium peroxide fusion ICP-MS finish for 34 elements.
QA/QC is done in house by Doré Copper Geologists with oversight from the Vice President Exploration. The check samples (blanks and standards – 4% of total samples with another 2% of core duplicates) that were inserted into the sample batches are verified against their certified values and are deemed a pass if they are within three standard deviations of the certified value. The duplicates are evaluated against each other to determine mineralization distribution (nugget). If there are large discrepancies in the check samples, then the entire batch is requested to be re-assayed.

Toronto, Ontario – November 18, 2022 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) is pleased to announce that it has entered into an agreement (the “Amending Agreement“) on October 28, 2022 to amend the earn-in option agreement (the “Option Agreement“) dated January 2, 2020 between the Company and Ressources Jessie Inc. (“Ressources Jessie“) pursuant to which the Company has an option to acquire the Joe Mann Property (the “Property“) from Ressources Jessie, as previously announced on January 2, 2020. The Joe Mann mine, located 60 kilometers south of Chibougamau, Quebec, produced 1.12 million ounces of gold at an average grade of 8.26 g/t from the 1950s to 20071. The deposit has an inferred resource of 680,000 tonnes grading 6.78 g/t Au and 0.24% Cu, which was included in the Company’s Preliminary Economic Assessment (PEA) of its hub-and-spoke operation announced on May 10, 20222.
Pursuant to the terms of the Amending Agreement, the Company has agreed to accelerate the final scheduled cash and share payments under the Option Agreement. The Company has made the final scheduled cash payment of $1,500,000 to Ressources Jessie (thus fulfilling the scheduled cash payment obligations), and will issue 3,333,333 common shares in the capital of the Company (“Common Shares“) to Legault Metals Inc. (“Legault“) at a deemed price of $0.30 per Common Share for an aggregate value of $1,000,000 upon acceptance of the TSX Venture Exchange (thus fulfilling all scheduled share payment obligations). The deadline for the Company to incur the remaining exploration expenditures on the Property, totaling approximately $830,000, has also been extended to February 28, 2023.
Following the fulfillment of the scheduled cash and share payment obligations, Ressources Jessie will commence the transfer of the Property to the Company. Upon exercise of the option, the Company is required to grant to Ressources Jessie a 2% net smelter return (“NSR“) royalty on the mine production from the Property. The Company will be entitled to buy back 1% NSR in consideration for a payment to Ressources Jessie of $2,000,000 and to buy back an additional 0.5% NSR in consideration for a payment to Ressources Jessie of $4,000,000.
Pursuant to the original terms of the Option Agreement, upon the commencement of commercial production at the Property, Doré Copper will make an additional $1,000,000 cash payment to Ressources Jessie and issue $1,500,000 in Common Shares to Legault.
The Company is currently drilling a hole on the eastern side of the Joe Mann mine, below the deepest mined level, to test the down plunge extension of a historical underground hole that returned 9.33 g/t Au over 2.4 meters (U-9161_D). In early 2023, the Company plans to test a geophysical anomaly located approximately 500 metres south of the mine.
