Toronto, Ontario – July 24, 2024 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC; OTCQB: DRCMF; FRA: DCM) 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 (“Campbell”) on two levels (114 meters and 200 meters) 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 Doré Fault.  

The two drill holes completed by Doré Copper targeting the Southwest Zone to the southeast intersected two zones of copper mineralization within strong ductile shear zones with intense hydrothermal alteration. Hole CDR-24-09 intersected 1.6 meters of 1.06% Cu and 20.7 g/t Ag, including 0.6 meter of 2.82% Cu, 54.8 g/t Ag and 0.33 g/t Au, at a vertical depth of 414 meters. The mineralized intersection is characterized by strong pervasive carbonate-chlorite-sericite alteration with banded semi-massive chalcopyrite and pyrrhotite associated with quartz veinlets. Hole CDR-24-10 intersected a wide shear structure of +130 meters (true width) characterized by pervasive black chlorite and carbonate veining alteration starting at a vertical depth of 449 meters. 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 Doré 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.

Doré 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 20212024 or PSEM-MCS), which is overseen by the Ministry of Natural Resources and Forests (Ministère des Ressources naturelles et des Forêts or MRNF). 

Ernest Mast, President and CEO of Doré Copper, commented, “We have confirmed the extension of the Cedar Bay Southwest structure towards the Lac Doré fault in two drill holes, including 1.6 meters of 1.06% Cu and 20.7 g/t Ag. We are very excited by the strong alteration in a wide shear zone characteristic of the large copper-gold ore bodies in the camp, including Doré Copper’s Copper Rand and Cedar Bay mines.  The next step is to conduct a downhole geophysical survey (pulse EM) to identify the potential for larger mineralized zones along the structure followed by additional drilling. We would also like to thank the Government of Québec for exploration grant and their support to develop the critical and strategic minerals industry within the province.”

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. 

Doré Copper 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)3. During 2020, the Corporation completed 9,025 meters of drilling and successfully extended a number of mineralized lenses (the 10-20A and 10-20B).

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 (HQ size half core) preparation and fire assay analysis were done at ALS Canada Ltd. (“ALS”) in Val-d’Or, Québec, and ICP multi-elements analysis was done at ALS in Vancouver, B.C. Samples were weighed, dried, crushed to 70% passing 2 mm, split to 250 g, and pulverized to 85% passing 75 microns. Samples are fire assayed for gold (Au) (50 g) and Aqua Regia ICP-AES finish for key elements (Ag, Cu, Mo). Samples assaying >10.0 g/t Au are re-analyzed with a gravimetric finish using a 50 g charge. 

QA/QC is done in house by Doré Copper geologists with oversight from the Senior Geologist. The check samples (blanks and standards – 4% of total samples with another 2% of core duplicates taken on half split core) that were inserted into the sample batches are verified against their certified values and are deemed a pass if they are within 3 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.

Youssouf Ahmadou, M.Sc., P.Geo., Senior Exploration Geologist of the Company and a QP within the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects, has reviewed and approved the scientific and technical information contained in this news release.

The Qualified Person (“QP”) for the Company has not verified the historical sample analytical data disclosed within this release. While the Company has obtained all historic records including analytical data from the previous owners of the Property and from various government databases, the Company has not independently verified the results of the historic sampling.

Dore Copper enters into an Agreement to acquire claims next to its flagship Corner Bay High-Grade Copper deposit 

   Download PDF   English   |   French

Toronto, Ontario – July 3, 2024 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC; OTCQB: DRCMF; FRA: DCM) is pleased to announce it has entered into an agreement with SOQUEM to acquire a 56.41% interest in a group of contiguous claims (the “Claim Group”) located immediately north and east of its flagship high-grade Corner Bay copper project in the Chibougamau mining camp, approximately 55 kilometers by road from Chibougamau, Québec. 

The Claim Group totals 17 claims covering an area of 446 ha within Dore Copper’s 100% owned Corner Bay-Devlin Property (5,446 ha) (Figure 1). The Claim Group has seen historical exploration during the 1970’s with 36 diamond drill holes totaling approximately 7,610 meters. Further exploration activities was carried out by SOQUEM between 1992 and 1998 with 28 diamond drill holes totaling 5,327 meters.  

Several parallel shear zones trending northwest-southeast were identified over a strike length of 1.4 kilometers (A, B, C, and D in Figure 1). The mineralization is characterized by narrow quartz+calcite veins (generally <1 metre) which generally contain between 10% and 40% chalcopyrite and pyrite. The mineralized zones have been tested to a vertical depth of 400 meters.

Significant historical drill intercepts on the Claim Group include1: 

  • 13.15% Cu over 0.61 meters (R1-12)
  • 5.45% Cu over 2.40 meters, including 13.9% Cu over 0.80 meters (4018-95-12)
  • 8.92% Cu over 0.91 meters (R1-31)
  • 12.45% Cu over 0.43 meters (R1-11)
  • 15.26% Cu over 0.76 meter (R1-33A)
  • 9.8% Cu over 1.25 meters (4018-95-21)
  • 12.37% Cu over 0.91 meters (R1-10)

More importantly, the potential northern strike extension of the Corner Bay deposit has never been tested on the Claim Group. The current northern limit of the Corner Bay mineral resource is approximately 430 meters south of the property boundary. Access to the Claim Group would provide an additional 800 metres along strike to test the possibility of a northern extension. In addition, a target of interest is the area of intersection between the north-south Corner Bay shear zone and the northwest-southeast shear zones of the Claim Group. Further compilation of historical geophysical surveys will assist in refining these targets. 

Ernest Mast, President and CEO of Doré Copper, commented, “The acquisition of SOQUEM’s Claim Group further consolidates the land position around our flagship Corner Bay copper deposit. High-grade copper shear zones, with similar mineralization to the Corner Bay deposit, have already been identified on the Claim Group. There are also indications that the Corner Bay deposit could extend northwards into the newly acquired claims. We plan to review and incorporate all the available data into our geological model to better define the areas which have not been adequately followed for future exploration plans.”

Terms of Agreement

Upon execution of the Agreement, SOQUEM is to receive (i) a cash payment of $20,000 and (ii) equivalent of $125,000 in common shares of the Company as consideration for the purchase of a 56.41% interest in the Claim Group. In addition, in the event that the Company completes a mineral resource estimate in accordance with NI 43-101 on the Claim Group, the Company will pay SOQUEM the sum of $100,000. On commencement of commercial production (defined as greater than 200 tonnes per day for a consecutive period of seven days), the Company will pay SOQUEM the sum of $250,000 and a 1% Net Smelter Return royalty (the “NSR”) on the production of copper and gold. The Company will have the right, at any time prior to the commencement of commercial production, to purchase 50% of the NSR for $500,000 and the other 50% for $1,000,000. The closing of the Agreement is subject to the approval of the Company’s filings with the TSX Venture Exchange.

Toronto, Ontario – March 27, 2024 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) reports that it has completed its first review of the Norhart mineralized zone, one of the priority gold targets identified on the recently acquired 65% interest in claims surrounding the Company’s 100% owned Joe Mann property. SOQUEM holds the remaining 35% interest in the joint venture (the “Joe Mann SOQUEM JV Property”) (refer to news release dated January 22, 2024). 

The Norhart gold occurrence is located approximately 1 kilometer north-northeast of the former Joe Mann mine and is easily accessible by road (Figure 1). It is comprised of five parallel east-west, sub-vertical quartz vein structures, each separated by approximately 50 to 150 meters, and traced over a strike length of more than 1 kilometer. Gold mineralization occurs in quartz shear and extensional veins with sulphides (trace to 10%) within an altered sequence of basaltic lava and felsic intrusions. 

The Norhart zone was discovered in 1995 by SOQUEM. From 1995 to 2005, a total of 68 diamond drill holes totaling 18,569 meters were completed to test the mineralized structures of Norhart over a strike length of 1.2 kilometers to a depth of less than 400 meters. During this period, a total of five parallel auriferous structures known as the Norhart, 2800, 3100, 3500 and 3900 zones were identified. The best gold intercepts were encountered in the 2800 zone, located 50 meters north of the Norhart zone and 2,800 feet (853 meters) north of the Joe Mann shaft. The high-grade gold envelope (intercepts of > 8 g/t Au) has a lateral extension of approximately 200 meters and remains open below 250 meters vertical. Long sections of the 3100, 2800 and Norhart zones (from north to south) are shown in Figure 2. 

Ernest Mast, President and CEO of Doré Copper, commented, “The Norhart high-grade gold target merits additional exploration work. The easy access to the Norhart zones, similar mineralogy and gold grades to Joe Mann make Norhart a potential target into the Company’s hub-and-spoke strategy for the Chibougamau mining camp. We plan on reviewing this target with SOQUEM to develop a drill program that will aim at expanding the mineralized zones and verifying historical intercepts.” 

Significant historical drill intercepts of the Norhart zones include:1 

2800 Zone 

  • 65.85 g/t Au and 5.9 g/t Ag over 6.34 meters (H-04-579)
  • 81.00 g/t Au and 1.4 g/t Ag over 1.2 meters (H-04-580) 
  • 26.30 g/t Au over 0.86 meter (H-04-588)
  • 6.27 g/t Au over 1.8 meters (H-04-571)
  • 9.33 g/t Au over 2.0 meters (H-04-573)

3100 Zone 

  • 14.85 g/t Au over 1.4 meters (H-04-586)
  • 14.56 g/t Au over 1.09 meters (H-04-580)
  • 5.55 g/t Au over 5.5 meters (H-572)

Norhart Zone: 

  • 24.65 g/t Au, 17.48 g/t Ag, and 0.79% Cu over 1.92 meters (H-04-578) 
  • 6.31 g/t Au over 4.75 meters (H-05-608)
  • 30.08 g/t Au over 1.0 meter (H-569)
  • 8.58 g/t Au over 2.95 meters (H-05-604)
  • 57.65 g/t Au over 0.40 meter (H-550)

The Joe Mann Property

The Company has a controlling interest in a contiguous group of claims totaling 6,209.2 ha surrounding the former high-grade Joe Mann gold mine (Dore Copper has a 100% ownership in 3,179.6 ha and a 65% ownership in 3,029.6 ha, as part of the Joe Mann SOQUEM JV) (Figure 1). The property is located 60 kilometers south of the Company’s Copper Rand mill and part of the southern Chibougamau mining camp where Northern Superior Resources Inc. and IAMGOLD Corporation have identified significant gold mineral resources.  

The Joe Mann property is located in the eastern part of the Abitibi Greenstone Belt within the upper part of the Obatogamau Formation, within a major deformation corridor known as the Opawica-Guercheville shear zone. The Company has a 100% interest in the former Joe Mann mine, which produced 1.12 million ounces of gold at an average grade of 8.26 g/t from the 1950s to 2007.1 The deposit has an inferred mineral 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, 2022.2

A number of gold occurrences and mineralized zones have been identified on the Joe Mann SOQUEM JV Property. No significant exploration work on the joint venture land has been carried out since the late 1990s, except for the Rohault and Norhart gold occurrences where the latest exploration activities took place in 2005.

Doré Copper increases size of its Joe Mann Property by acquiring a 65% interest in 3,030 hectares

   Download PDF   English   |   French

Toronto, Ontario – January 22, 2024 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) is pleased to announce that it has exercised its right to acquire a 65% interest in certain claims subject to a joint venture with SOQUEM (the “SOQUEM JV Property“), which surround and are adjacent to the Company’s 100% owned Joe Mann Property, pursuant to an earn-in option agreement (the “Option Agreement“) dated January 2, 2020, as amended October 28, 2022, between the Company and Ressources Jessie Inc. (“Ressources Jessie“). SOQUEM holds the remaining 35% interest in the SOQUEM JV Property. 

In accordance with the terms of the Option Agreement, Ressources Jessie will transfer its 65% interest in the SOQUEM JV Property, comprising 69 claims totaling 3,029.6 ha, to the Company for $300,000 in cash and 3,333,333 common shares of the Company at a deemed price of $0.12 per common share, representing $400,000 in common shares. Following this acquisition, the Company has a controlling interest in a contiguous group of claims totaling 6,209.2 ha surrounding the former high-grade Joe Mann gold mine (Figure 1) and part of the southern Chibougamau Camp where Northern Superior Resources Inc. and IAMGOLD Corporation have significant gold mineral resources (Figure 2).   

The acquisition is subject to the acceptance of the TSX Venture Exchange. The common shares issued in connection with the acquisition are subject to a four month hold period under applicable Canadian securities laws which will expire on May 23, 2024.

Ernest Mast, President and CEO of Doré Copper, commented, “With this transaction, we have consolidated a large contiguous group of claims around the former Joe Mann mine in the prolific southern Chibougamau camp. Most of the SOQUEM JV block has not been explored since the late 1990s and numerous gold targets remain to be evaluated on the property. We are looking forward to work with SOQUEM and we plan to commence a detailed review of the historical work and use new geological interpretations to generate high quality exploration targets.” 

Exploration Potential on the SOQUEM JV Property

The Company’s contiguous group of claims (Figure 1) is located in the eastern part of the Abitibi Greenstone belt within the upper part of the Obatogamau Formation, within a major deformation corridor known as the Opawica-Guercheville shear zone. The Company has a 100% interest in the former Joe Mann mine, which produced 1.12 million ounces of gold at an average grade of 8.26 g/t from the 1950s to 2007.1 The deposit has an inferred mineral 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, 2022.2

The main lithologies encountered are basalts, rhyolites, gabbros and several families of felsic, intermediate and mafic dykes. Two felsic intrusions, La Dauversière and Verneuil, are found respectively to the northeast and northwest of the claim group. The stratigraphy is east-west, dipping sub-vertically, and metamorphosed to the upper greenschist facies (epidote-amphibolite facies). 

A number of gold occurrences and mineralized zones have been identified on the SOQUEM JV Property and are briefly summarized below. An evaluation of all the exploration work conducted on the SOQUEM JV will be completed over the coming months to identify exploration targets. No significant exploration work on the SOQUEM JV Property has been carried out since the late 1990s, except for the Rohault and Norhart gold occurrences where the latest exploration activities took place in 2004. 

Rohault

The Rohault gold occurrence is located north of the former Joe Mann mine and its western extension is located approximately 300 meters north of the mine infrastructures. This structure has been tested by drilling over a 2 kilometer strike length. The Rohault mineralized zone is characterized by quartz-carbonate veins and veinlets which cut mafic lavas and intrusions. The main occurrence contains approximately 15% pyrite and 5% chalcopyrite with several interesting historical drill intercepts: 108.71 g/t Au, 16.85 g/t Ag and 1.4% Cu over 0.6 meter at a downhole depth of 44.95 meters (H-560) and 6.32 g/t Au and 0.37% Cu over 3.6 meters (including 34.5 g/t Au and 0.99% Cu over 0.6 meter) at a downhole depth of 79.2 meters (H-518).1

Norhart

The Norhart gold occurrence is located approximately 1 kilometer north of former Joe Mann mine. The gold mineralization shows similar characteristics to Joe Mann. It is comprised of five parallel quartz vein structures, separated by between 50 and 150 meters over a strike length of approximately 500 meters. Gold mineralization is within quartz veins cutting strongly altered granular felsic dykes or basalts. 

Significant historical drill intercepts in the sector of Norhart include: 65.85 g/t Au, 5.9 g/t Ag over 6.34 meters at a downhole depth of 207.46 meters (H-04-579); 160.50 g/t Au, 9.8 g/t Ag over 0.85 meters at a downhole depth of 235.0 meters (H-04-582); 81 g/t Au, 1.4 g/t Ag over 1.2 meters at a downhole depth of 234.8 meters (H-04-580); 24.65 g/t Au, 17.48 g/t Ag, 0.79% Cu over 1.92 meters at a downhole depth of 256.62 meters (H-04-578), 99.64 g/t Au, 11.8 g/t Ag and 0.12% Cu over 0.3 meter at a downhole depth of 283.85 meters (H-569); 10.04 g/t Au, 16.3 g/t Ag and 0.11% Cu over 1.2 meters at a downhole depth of 521.2 meters (H-535 EXT); 57.65 g/t Au over 0.40 meter at a downhole depth of 264.0 meters (H-550).1 ,3 

Currie-Mills

The Currie Mills (Lac James) gold occurrence is located 3 kilometers east-northeast of the former Joe Mann mine. The mineralized system is parallel to Joe Mann and contains a small historical near-surface resource (not compliant with NI 43-101). Mineralization consists of two lenses (North and South) of disseminated chalcopyrite, pyrite, pyrrhotite and arsenopyrite in centimetric to decimetric quartz-carbonate veins with locally some specks of free gold with altered and sheared non-magnetic coarse gabbros. One significant historical drill hole intercept of 3.9 /t Au over 6.9 meters at a downhole depth of 61 meters (VM87-07) is located 150 meters east of the historical resource.1,4 

Lac Meston

The Lac Meston gold occurrence is located 4.8 kilometers southwest of the former Joe Mann mine. The mineralization is found in a tonalite intrusion. An underground ramp of 305 meters was built in 1974 but did not access the mineralized zone. Significant historical drill hole intercepts include: 18.49 g/t Au over 3.61 meters (M-81-09), 34.21 g/t Au over 1.55 meters (A-12) and 6.92 g/t Au over 6.10 meters (A-14), all of which were at less than 100 meters depth.1,5,6

Adnor

The Adnor mineralized zone, located 3 kilometers west of Joe Mann, consists of a number of east-west subparallel veins within a sequence of pillowed massive basaltic flows injected by a variety of small felsic dykes. A significant drilling campaign was conducted in the early 1950s to define the mineralized zone. The highest drill intercept returned 2,297 g/t Au over 0.30 m (A-10). A subsequent drilling program in the early 1970s returned the following significant results: 14.40 g/t Au over 0.3 meter (N-7-2); 6.86 g/t Au over 0.6 meter (N-6); and 4.80 g/t Au over 1.5 meters (N-7). Highlight from the subsequent late 1980s drilling program include 11.04 g/t over 3.05 meters (H-380).1,7

Noranda – La Dauversière

This mineral occurrence is located approximately 3.5 kilometers east of Joe Mann. Gold mineralization is found in quartz carbonate veins with pyrrhotite-pyrite and chalcopyrite within sheared and altered gabbro. A number of diamond drill holes were completed by several companies prior to the late 1990s and significant results included: 8.16 g/t Au, 2.4 g/t Ag and 0.16% Cu over 0.55 meter (H-223); and 12.3 g/t Au over 1.02 meters (VM-89-26).1

Montgomery 

This mineral showing is located approximately 2 kilometers west of Joe Mann. Gold mineralization is found in quartz veins containing varying amounts of pyrite, scheelite, chalcopyrite and local visible gold within a sheared structure covering a strike length of 475 meters and up to 8 meters wide. Significant historical intersections include: 4.41 g/t Au over 0.27 meter (M-7); 106.10 g/t Au (trench # 1 channel sample); 13.56 g/t Au (trench # 2 channel sample); and 199.66 g/t Au (trench # 4 channel sample).1

Wright Hargreaves

The mineral showing (also known as “Fancamp”) is located 500 meters southwest of the Adnor showing. Gold mineralization is erratic and associated with <1 meter quartz-carbonate+/-tourmaline veins and veinlets with auriferous pyrite in massive and pillowed basalts and co-magmatic magnetic gabbro-sills. Historical trench results include 9.88 g/t Au over 1.0 meter and 6.05 g/t Au over 1.0 meter. The only significant highlight from the latest drilling program (1980s) include 4.50 g/t over 0.60 meter (87-1).1

Lac Antoine

Located near the southwest boundary of the property, the Lac Antoine gold mineralization is associated with northeast trending quartz-carbonate veins containing up to 15% pyrite and minor chalcopyrite within pillow basalts. Historical work only reports high-grade gold assays (10 to +30 g/t Au) from grab samples.1

Bloc Sud

Located near the southwest boundary of the property, the Bloc Sud gold mineralization consists of black quartz veins (+/- sulphides) within a chlorite-sericite-ankerite schist of decametric width at the contact of a basalt-tonalite dyke. An intercept of 1.96 g/t Au over 6.25 meters, including 6.98 g/t Au over 1.35 meters (H-507), was reported from a limited drilling campaign.1

The net proceeds of the Rights Offering will be used for exploration and development activities and for working capital and general corporate purposes.

Under the terms of the Rights Offering, holders of Common Shares at the close of business (Toronto time) on November 28, 2023 (the “Record Date“) will receive 0.337167854796804 of one transferable right (each whole right, a “Right“) for each Common Share held as of the Record Date. All fractional Rights will be rounded down to the nearest whole number of Rights with no additional compensation paid therefor. Each Right will entitle the holder thereof to subscribe for one Common Share (the “Basic Subscription Privilege“) at a subscription price of $0.12 per Common Share (the “Subscription Price“). The Subscription Price represents a 25% discount to the last closing price of the Common Shares on the TSX Venture Exchange prior to the announcement of the Rights Offering. Pursuant to applicable securities laws, and to the extent that other holders of Rights do not exercise all of their Rights under the Basic Subscription Privilege, each holder of Rights who fully exercises its Basic Subscription Privilege will also be entitled to subscribe for additional Common Shares on a pro rata basis at the Subscription Price in the manner prescribed by securities laws and as further detailed in the Rights Offering Circular (as defined below). The Rights Offering is expected to expire at 5:00 p.m. (Toronto time) (the “Expiry Time“) on December 22, 2023 (the “Expiry Date“). Any Rights not exercised at or before the Expiry Time on the Expiry Date will be void and will have no value.

The Rights will be listed on the TSX Venture Exchange under the trading symbol “DCMC.RT” commencing on November 27, 2023 and will be posted for trading until 12:00 p.m. (Toronto time) on the Expiry Date. 

The completion of the Rights Offering is conditional upon the satisfaction of certain conditions, including, but not limited to, the receipt of all necessary regulatory approvals, including the final acceptance of the TSX Venture Exchange.

In connection with the Rights Offering, the Corporation has entered into a standby commitment agreement (each, a “Standby Commitment Agreement“) with Ocean Partners UK Limited (“Ocean Partners“) and Equinox Partners Investment Management, LLC (together with Ocean Partners, the “Standby Purchasers“), pursuant to which the Standby Purchasers have each agreed, subject to certain terms and conditions, to exercise its Basic Subscription Privilege in respect of any Rights it holds, and, in addition thereto, to acquire any additional Common Shares available as a result of any unexercised Rights under the Rights Offering (each, a “Standby Commitment“), with each Standby Purchaser purchasing 50% of such Common Shares, such that the Corporation will, subject to the terms of the Standby Commitment Agreements, be guaranteed to issue 33,000,000 Common Shares in connection with the Rights Offering for aggregate gross proceeds to the Corporation of approximately $3,960,000.

Each of the Standby Purchasers is a “related party” of the Corporation under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101“) because each has beneficial ownership of, or control or direction over, directly or indirectly, more than 10% of the issued and outstanding Common Shares. The Rights Offering is not subject to the related party transaction rules under MI 61-101 based on a prescribed exception related to rights offerings.

Further details on the Rights Offering, including eligibility requirements for shareholders to participate and the procedures to be followed by shareholders in order to subscribe for Common Shares, will be included in a rights offering circular (the “Rights Offering Circular“), a rights offering notice (the “Rights Offering Notice“), a notice to ineligible holders (the “Notice to Ineligible Holders“) and the Standby Commitment Agreements which will be available under the Corporation’s issuer profile on SEDAR+ at www.sedarplus.ca. It is expected that a copy of the Rights Offering Notice, a direct registration system advice representing the Rights (“Rights DRS Advice“) and a subscription form (“Subscription Form“) will be mailed to each registered shareholder of the Corporation resident in the Eligible Jurisdictions (as defined below) as at the Record Date. Registered shareholders who wish to exercise their Rights must forward the Rights DRS Advice, together with the completed Subscription Form and the applicable funds, to the rights agent, Computershare Investor Services Inc., at or before the Expiry Time. Shareholders who own their Common Shares through an intermediary, such as a bank, trust company, securities dealer or broker, will receive materials and instructions from their intermediary. 

The Rights Offering will be conducted only in the provinces and territories of Canada (the “Eligible Jurisdictions“). Accordingly, and subject to the detailed provisions of the Rights Offering Circular, Rights will not be delivered to, nor will they be exercisable by, persons resident outside of the Eligible Jurisdictions unless such holders can establish that the transaction is exempt under applicable legislation. Rather, such Rights may be sold on their behalf. If you are a holder of Common Shares and reside outside of Canada, please review the Rights Offering Notice, the Rights Offering Circular and the Notice to Ineligible Holders to determine your eligibility and the process and timing requirements to receive and exercise your Rights. The Corporation requests that any ineligible holder interested in exercising their Rights contact the Corporation at their earliest convenience.

Neither the Rights being offered or the Common Shares have been or will be registered under the United States Securities Act of 1933, as amended, and may not be exercised, offered or sold, as applicable, in the United States absent registration or an applicable exemption from the registration requirements. This news release shall not constitute an offer to sell or the solicitation of an offer to buy the securities of the Corporation. There shall be no offer or sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification of such securities under the laws of any such jurisdiction. 

In order to ensure that the Corporation can meet its short‐term obligations prior to the closing of the Rights Offering, the Corporation has entered into a bridge loan agreement with Ocean Partners, pursuant to which Ocean Partners has agreed to provide an unsecured short-term loan to the Corporation in the amount of C$250,000 and bearing interest at a rate of 15% per annum (the “Bridge Loan“). The Bridge Loan constitutes a “related party transaction” for the purposes of MI 61-101 as Ocean Partners is a “related party” of the Corporation. The Corporation is exempt from the requirements to obtain a formal valuation or minority shareholder approval in connection with the Bridge Loan in reliance on sections 5.5(a) and 5.7(1)(a), respectively, of MI 61-101, as the fair market value of the Bridge Loan does not exceed 25% of the Corporation’s market capitalization as calculated in accordance with MI 61-101.

Dore Copper reports excellent concentrate grades and recoveries with low impurity element concentrations from flotation tests at its Corner Bay project

   Download PDF   English   |   French

Toronto, Ontario – October 30, 2023 – Doré Copper Mining Corp. (the “Company” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) is pleased to announce positive flotation test results at 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. This metallurgical test program is part of the work that is designed to support completion of a feasibility study for the implementation of a hub-and spoke operation model.

Key Highlights from “Lock Cycle” Flotation Tests

  • Excellent copper recoveries of 98.2% and 96.8% from a representative composite sample
  • High-quality copper concentrate grades results of 27.0% and 29.6% 

The results are an improvement over the figures included in the May 2022 preliminary economic assessment (“PEA”), where the flotation recoveries for copper were 96.7% and the copper concentrate grade was 23.7%. All metallurgical tests completed to date support the effectiveness of utilizing ore sorting technology to improve the mill feed grade and reduce the mill feed tonnage resulting in a high-quality salable copper concentrate.

Ernest Mast, President & CEO, stated, “These flotation test results validate the favorable mineralogy of the Corner Bay deposit for high performance ore sorting technology and conventional flotation to produce a high-quality copper concentrate containing low levels of deleterious metals. These figures demonstrate the robust nature of the processing plant flowsheet that will be used in the feasibility study.” 

Metallurgical Test Work Program Summary

Base Metallurgical Laboratories in Kamloops, British Columbia was commissioned to complete Corner Bay metallurgical development and locked cycle flotation testing in support of the feasibility study.

A total of 34 diamond drill holes were used to create a spatially diverse composite sample (the “CBSP” composite) that intersected copper mineralized zones within the Corner Bay Mineral Resource estimate.  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 CBSP composite was firstly compiled into a 202 kilogram sample with a grade of 2.20% Cu. The CBSP composite was then processed through the Steinert ore sorter and mixed with 26% of the unsorted underflow by-passed mineralized material to represent an overall sorted pre-concentrate mineralized material product. The CBSP composite resulted in a 123 kilogram sample with a grade of 3.31% Cu.

The composite sample was evaluated through lock cycle tests to determine the flotation metallurgical performance.  The sample was prepared to a nominal grind size of 140 microns K80 in the rougher testing and then processed through a regrind size of approximately 37 microns K80 in the cleaner tests. 

The sample responded consistently throughout the test work with excellent performance to conventional flotation processing methods and reagents. Two locked cycle tests were completed with varying retention times to determine the concentrate grade versus recovery. The tests resulted in concentrate grades of 27.0% Cu and 29.6% Cu and recoveries 98.2% and 96.8%, respectively (see Table 1).  

Minimal amounts of deleterious elements (e.g. arsenic, antimony, bismuth, cadmium etc.) were present in the concentrate, indicative of the “clean” nature of the concentrate (see Table 2). These results showed the highly commercial quality of the concentrate in terms of salability and payment terms of smelters.

Forward-looking statements include predictions, projections and forecasts and are often, but not always, identified by the use of words such as “seek”, “anticipate”, “believe”, “plan”, “estimate”, “forecast”, “expect”, “potential”, “project”, “target”, “schedule”, “budget” and “intend” and statements that an event or result “may”, “will”, “should”, “could” or “might” occur or be achieved and other similar expressions and includes the negatives thereof. All statements other than statements of historical fact included in this news release, including, without limitation, statements with respect to the timing and ability of the Company to receive necessary regulatory approvals, the Company’s ability to meet its production target, the commencement, timing and completion of a feasibility study, and the plans, operations and prospects of the Company and its properties are forward-looking statements. Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable, are subject to known and unknown risks, uncertainties and other factors which may cause actual results and future events to differ materially from those expressed or implied by such forward-looking statements. Such factors include, but are not limited to, actual exploration results, changes in project parameters as plans continue to be refined, future metal prices, availability of capital and financing on acceptable terms, general economic, market or business conditions, uninsured risks, regulatory changes, delays or inability to receive required regulatory approvals, health emergencies, pandemics and other exploration or other risks detailed herein and from time to time in the filings made by the Company with securities regulators. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ from those described in forward-looking statements, there may be other factors that cause such actions, events or results to differ materially from those anticipated. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
