Doré Copper Reports High-Grade Gold Mineralization at Gwillim Including 9.67 g/t Au Over 5.3 Metres

Doré Copper Reports High-Grade Gold Mineralization at Gwillim Including 9.67 g/t Au Over 5.3 Metres

Doré Copper Mining Corp. (the “Corporation” or “Doré Copper”) (TSXV: DCMC; OTCQX: DRCMF; FRA: DCM) announces positive assay results from the first of two drill holes completed in late 2022 on the KOD zone of the Gwillim property, which is under a 50/50 joint venture with Argonaut Gold Inc. (through its wholly owned subsidiary Prodigy Gold Inc.). Doré Copper is the operator of the joint venture. Gwillim is located approximately 8 kilometers by road northwest of Chibougamau, Québec.

Drilling Highlights


  • Zone B: 9.67 g/t Au over 5.3 meters (visible gold)
  • Zone C: 11.10 g/t Au over 3.0 meters

In addition to the drilling program, the joint venture completed a 146 line-kilometer VTEMTM airborne electromagnetic survey over the property and a televiewer acoustic and optical survey in seven drill holes of the KOD zone. The VTEM™ survey results have identified several conductive anomalies. Specifically, one large anomaly is located at the KOD zone starting at a depth of 150 meters, just west of holes KOD-22-04 and 05.

Ernest Mast, President and CEO of Doré Copper, commented, “The limited drilling to date on the KOD zone is demonstrating good continuity of the high-grade gold mineralization from surface to a vertical depth of approximately 600 meters and the system remains open at depth. Further work is warranted to test the strike and depth extension of the KOD zone, along with a number of conductive anomalies.”

Gwillim Drilling Program

Doré Copper drilled two holes totaling 1,320 meters in December 2022 to follow up on positive results from two holes completed the prior year on the KOD zone (Table 1), located 300 meters south of the mined Gwillim Main zone (refer to news release April 21, 2022). Hole KOD-22-04 intersected two main mineralized zones, of 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 are interpreted as zones B and C of the KOD mineralized structure (Figures 1 and 2, and Table 1). These gold intercepts in zones B and C are located approximately 190 and 215 meters, respectively, below hole KOD-21-03. In addition, a wide zone of low-grade mineralization, 0.86 g/t Au over 42.3 meters, was intersected from 460 to 502.3 meters. Assays are pending from 130 to 323.5 meters.

The KOD mineralized system remains open along strike and below 600 meters. Assays are pending for hole KOD-22-05, drilled on the same pad as KOD-22-04 and approximately 60 meters west-southwest of zone B intersected in KOD-22-04.

Gold mineralization in the KOD zone is found mainly in millimetric to centimetric quartz veins intersecting the massive basalt unit close to the contact with gabbroic or quartz-feldspar (“QFP”) dykes, which range from 30 centimeters to 10 meters. In some places, these veins can take the expression of silica flooding in basaltic pillow rims, associated with pyrite, pyrrhotite and chalcopyrite. Visible gold is occasionally observed.

A televiewer acoustic and optical survey was conducted in seven holes (87-KOD-20, 87-KOD-21, KOD-18-01, KOD-21-02, KOD-21-03, KOD-22-04 and KOD-22-05) to gain a better understanding of the orientation of the mineralized zones and the QFP dykes. The analysis and survey results will be available once the assays have been received for KOD-22-05.

In January 2023, Doré Copper and its joint venture partner contracted the services of Geotech to carry out a 146 line-kilometre airborne VTEM™ survey over the joint venture property. The flight lines were flown at a 75 meter spacing. The objective of the geophysical survey is to outline any conductors that could represent masses of sulphides. A number of anomalies have been identified in this survey and are expected to be followed up in the field starting in the summer of 2023. A significant, large anomaly is located on the KOD zone starting at a depth of 150 meters, just west of holes KOD-22-04 and 05 (shown on Figure 2).
