Doré Copper Provides Update on Its Project Activities

TORONTO, Aug. 01, 2023 (GLOBE NEWSWIRE) -- 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).
