Doré Copper Mining Corp. announced results from its drilling campaign of 1,557 meters completed in July 2023 at the Gwillim and Jaculet projects, both located near Chibougamau, Québec. 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. 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. 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. 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.
