Dore Copper identifies gold exploration potential at Norhart Zone, just North of the former Joe Mann mine 

   Download PDF   English   |   French

Toronto, OntarioMarch 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

Toronto, Ontario November 21, 2023 – Doré Copper Mining Corp. (the “Corporation” or “Doré Copper“) (TSXV:DCMC; OTCQX:DRCMF; FRA:DCM) is pleased to announce that it is commencing a rights offering (the “Rights Offering“) to the holders of common shares in the capital of the Corporation (“Common Shares“) to raise aggregate gross proceeds of approximately $3,960,000. 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.

Doré Copper reports exploration drill results – intersects shallow mineralization grading 4.4 g/t Au over 9.8 metres at Gwillim

   Download PDF   English   |   French

Toronto, OntarioOctober 17, 2023 – Doré Copper Mining Corp. (the “Corporation” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) announces results from its drilling campaign of 1,557 meters completed in July 2023 at the Gwillim and Jaculet projects, both located near Chibougamau, Québec. 

Ernest Mast, President and CEO of Doré Copper, commented, “Our summer drilling program at Gwillim has shown the potential of the Signal Zone, another high-grade mineralized zone to the north of the KOD Zones. The geological model for Gwillim continues to advance and further work is warranted to test the potential of these high-grade zones and to identify additional gold mineralized structures.” 

Gwillim

In July 2023, Doré Copper completed three holes totaling 957 meters at Gwillim. Hole KOD-22-05 was extended by 90 meters to test KOD Zone C and the other two holes (KOD-23-06 and 07) tested a geophysical anomaly (airborne VTEM™ survey conducted in January 2023), located immediately west of the KOD zone (refer to August 1, 2023 news release). 

Hole KOD-22-05E intersected KOD Zone C from 633 to 654 meters with anomalous gold values in several decimetric zones containing variable amounts of pyrite, pyrrhotite and chalcopyrite. 

Hole KOD-23-06 intersected a 1.7 meter interval (interpreted as KOD Zone A) containing stringers of chalcopyrite and sphalerite with a highly chloritized basalt. No significant gold mineralization was reported. 

Hole KOD-23-07 intersected the Signal Zone at a downhole depth of 15.5 metres with an intercept of 4.4 g/t Au over 9.8 meters, including 16.51 g/t Au over 2.3 meters, characterized by decimetric bands of massive pyrrhotite, pyrite and traces chalcopyrite. Results from a downhole geophysical survey completed in the hole shows an off-hole anomaly located approximately 100 meters down and west of this gold intercept. The KOD Zone envelope (Zones A, B1, B2, and C) was intersected from 358.5 to 462.3 meters, characterized by several intervals containing pyrite, pyrrhotite and chalcopyrite within the pillow rims (typical of the KOD Zone). No significant gold mineralization was reported.

The Signal Zone has been historically traced over a strike length of 600 meters and is approximately 200 meters north of the KOD Zone C. In the late 1980s, approximately 2,357 meters in 27 holes tested the Signal Zone. In addition, a number of historical holes were drilled from underground intercepting both the Signal and KOD Zones.The best historical gold intersections from the surface program (see reference 3) included: 7.1 g/t Au over 2.6 meters (SZ-87-6), 34.96 g/t Au over 1.37 meters (SZ-87-10), and 22.9 g/t Au over 1.2 meters (GL-41). Dore Copper hole KOD-21-02 had also intersected the Signal Zone with 3.33 g/t Au over 13.3 metres at a downhole depth of 28.0 meters. A compilation of this historical work is currently underway.

The KOD mineralized system remains open along strike to the east and below 600 meters. The Signal zone for its part remains open below 230 meters.

The Gwillim property is under a 50/50 joint venture with Argonaut Gold through its wholly-owned subsidiary Prodigy Gold with Doré Copper being the operator. 

Jaculet

Doré Copper completed one drill hole of 600 meters in July 2023, which tested the strike extension of Jaculet Zone 1, approximately 100 meters to the west of a previously mined out area and two high-grade copper intercepts in two historical holes, at a vertical depth of approximately 400 meters. The two surface historical holes from Chibougamau Jaculet Mines Ltd. in 1956 had intersected with 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 (refer to May 3, 2023 news release).

Hole JA-23-01 intersected 2.29% Cu and 0.36 g/t Au over 1.5 meters, mainly chalcopyrite in centrimetric veins at a downhole depth of 438 meters (Jaculet Zone 1). It is now interpreted that the mineralization in hole JA-23-01 is at the periphery of the main Jaculet Zone 1 ore shoot. The deposit remains open below 400 meters.

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 (half core) preparation was done at ALS Canada Ltd. (“ALS”) in Val-d’Or, Québec, and the fire assay and ICP analysis was done at ALS in Vancouver, B.C. Samples were weighed, dried, crushed to 75% passing 2 mm, split to 250 g, and pulverized to 85% passing 75 microns. Samples are fire assayed for gold (Au) (50 g) and sodium peroxide fusion ICP-MS finish for 34 elements. Samples assaying >10.0 g/t Au are re-analyzed with a gravimetric finish using a 50 g charge. If visible gold is observed in the sample, the assay is performed by metallic screening whereby the entire sample is crushed, a 1 kg portion is pulverized and screened to 106 µm and analyzed by 50 g fire assay with gravimetric finish.

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 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.

Doré Copper provides update on its project activities

   Download PDF   English   |   French   |   GERMAN

Toronto, OntarioAugust 1, 2023 – Doré Copper Mining Corp. (the “Corporation” or “Doré Copper“) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) provides an update on its project activities located near Chibougamau, Québec. 

Exploration Activities

During Q2 2023, the Doré Copper geology team focused on data compilation and interpretation for the Gwillim and Jaculet projects. A drilling program of 1,557 meters was completed in July 2023.

Gwillim

During Q4 2022, Doré Copper completed two drill holes (KOD-22-04 and 05) totaling 1,342 meters at the KOD Zone in the western part of the Gwillim property, which is under a 50/50 joint venture with Argonaut Gold through its wholly owned subsidiary Prodigy Gold with Doré being the operator. 

Doré Copper reported the results from the first hole on May 29, 2023. KOD-22-04 intersected 9.67 g/t Au over 5.3 meters, including 19.46 g/t Au over 2.1 meters, starting at a vertical depth of approximately 580 meters and 11.10 g/t Au over 3.0 meters, which after a new revised interpretation are interpreted as Zone C of the KOD mineralized structure. 

Hole KOD-22-05, drilled on the same pad as KOD-22-04 and approximately 60 meters west-southwest of Zone C intersected in KOD-22-04 was determined to have been stopped short of Zone C by approximately 50 meters and was therefore extended in the July drilling program (see below). 

In July 2023, Doré Copper completed three holes totaling 957 meters at Gwillim. Hole KOD-22-05 was extended by 90 meters to test Zone C and the other two holes (KOD-23-06 and 07) tested a geophysical anomaly (airborne VTEM™ survey conducted in January 2023), immediately west of the projected down plunge of the near-surface high-grade gold mineralization of Zone C. 

Hole KOD-22-05E intersected Zone C from 633 to 654 meters with several specks of gold observed at the beginning of Zone C and mineralization similar to KOD-22-04 Zone C. Hole KOD-23-06 intersected a 1.5 meter interval containing chalcopyrite and sphalerite in stringers. Hole KOD-23-07 intersected the Signal Zone (approximately 250 meters north of the KOD Zone C) characterized by several meters of massive pyrite, pyrrhotite and trace chalcopyrite and KOD Zones A, B and C. 

Assays for the three holes are expected in September. The KOD mineralized system remains open along strike to the west and below 600 meters. 

Jaculet

Doré Copper completed one drill hole of 600 meters in July 2023 to test the potential down plunge extension of high-grade copper mineralization intersected in two surface historical holes from Chibougamau Jaculet Mines Ltd. in 1956. Historical holes V17 and V17A (wedge from V17 and located approximately 50 meters to the east) intersected Jaculet Zone 1 at a vertical depth of approximately 400 meters with 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 (refer to May 3, 2023 news release).

Hole JA-23-01 intersected 1.5 meters of mineralization, mainly chalcopyrite in centrimetric veins, at a downhole depth of 438 metres (Jaculet Zone 1), approximately 12 meters below the interpreted location of the historical intercepts in V17 and V17A. It is now believed that the location of the historical holes is perhaps inaccurate and more to the east, in the area of the underground workings, indicating that the mineralization hit in hole JA-23-01 is at the periphery of the main ore shoot. Assays are pending for hole JA-23-01.

Corner Bay Metallurgical Test Work

During Q4 2022, a spatially diverse composite sample from the Corner Bay core was prepared for additional ore sorting tests at Steinert’s facility in Kentucky, United States, using a XRT sensor (X-ray transmission) and a laser sensor. The composite sample weighted 202 kg and graded 2.20% Cu, and included an 18% external mining dilution from the hanging wall and foot wall of the mineralized interval. The results, announced on April 18, 2023, showed a copper grade increase of 77% (from 2.20% to 3.93%) and copper recoveries in the order of 93.5% with the final reject portion representing 47.5% of the feed mass at a grade of 0.30% Cu. Results were equally positive for gold, silver and molybdenum. Lastly, the arsenic grade of the two pre-concentrates was found to be 12 ppm which leads to a final concentrate with low arsenic levels. 

During Q2 2023, a metallurgical test program was started at Base Metallurgical Laboratories in British Columbia.  A total of four spatially diverse composites were prepared, including the samples from the Steinert ore sorting tests.  The metallurgical test work will include grind size optimization, reagent determination, and grade-recovery curves for copper. Recoveries for gold, silver and molybdenum will also be determined, as well as minor element concentrations in the copper concentrate. The program will also include thickening and filtration testing. 

Preliminary results of the metallurgical test work indicate high rougher recoveries of +95% copper with little sensitivity to a grind size between 100 and 180 microns. Complete results are expected in Q3 2023.

Environmental and Social Assessment 

In June 2023, Doré Copper received the project directive for the environmental and social assessment of its proposed hub-and-spoke operation from the Quebec Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks (MELCCFP). The project directive is for the development of two underground mines (Corner Bay and Devlin), the rehabilitation of the Copper Rand mill and the use of the existing tailings management facility. 

Activities at Copper Rand Mill

During 2022, obsolete electrical cables from the Copper Rand mill were removed as part of the refurbishment program. During Q2 2023, the cables were stripped of their aluminum and rubber sheathing and the copper was sold as #1 copper scrap. 

The Corporation project sites and infrastructures were not impacted by the forest fires in northern Quebec. All fires in the Chibougamau area are currently under control. Doré Copper sincerely thanks all involved in mitigating the impacts of the forest fires in northern Quebec and keeping our employees and local communities safe. 

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 (half core) preparation was done at ALS Canada Ltd. (“ALS”) in Val-d’Or, Québec, and the fire assay and ICP analysis was done at ALS in Vancouver, B.C. Samples were weighed, dried, crushed to 75% passing 2 mm, split to 250 g, and pulverized to 85% passing 75 microns. Samples are fire assayed for gold (Au) (50 g) and sodium peroxide fusion ICP-MS finish for 34 elements. Samples assaying >10.0 g/t Au are re-analyzed with a gravimetric finish using a 50 g charge. If visible gold is observed in the sample, the assay is performed by metallic screening whereby the entire sample is crushed, a 1 kg portion is pulverized and screened to 106 µm and analyzed by 50 g fire assay with gravimetric finish.

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 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.

Sylvain Lépine, M.Sc, P.Geo, MBA, Vice President Exploration of the Corporation and a “Qualified Person” within the meaning of National Instrument 43-101, has reviewed and approved the technical information contained in this news release.
