Doré Copper Intersects 3.7 Meters at 9.41% Copper, 2.84 G/T GOLD and 36.5 G/T Silver at Corner BAY – Continues to Expand Deposit
PRESS RELEASE
DORÉ COPPER INTERSECTS 3.7 METERS AT 9.41% COPPER, 2.84 G/T GOLD
AND 36.5 G/T SILVER AT CORNER BAY – CONTINUES TO EXPAND DEPOSIT
Toronto, Ontario – January 19, 2022 – Doré Copper Mining Corp. (the "Corporation" or "Doré Copper")
(TSXV: DCMC; OTCQ X: DRCMF; FRA: DCM) is pleased to announce additional results from its 2021
drilling campaign at its flagship Corner Bay property, located in the Chibougamau mining camp,
approximately 40 kilometers by road from Chibougamau, Québec.
In 2021, Doré Copper completed 43 holes (including wedge holes) totaling 41,063 meters and is reporting
today the results from 13 holes. The assay results for the remaining 11 holes are pending. Prior results
were incorporated into the Mineral Resource Estimate announced on October 6, 2021.
These latest drill results have further expanded the deposit in three areas and will be incorporated , with
other pending results , into an updated Mineral Resource estimate of the Corner Bay deposit for the
preliminary economic assessment (“PEA”) anticipated at the end of the first quarter of 2022.
Drilling Highlights

• Main Vein below dyke connected to Lower Deep Lens with five holes, including CB-21-45 with
3.8 meters of 2.97% Cu, 0.45 g/t Au and 4.4 g/t Ag, CB-21-47 with 7.35 meters of 5.08% Cu, 0.27
g/t Au and 8.6 5 g/t Ag and CB-21-49 with 7.1 meters of 3.24% Cu and 0.23 g/t Au – Two other
mineralized holes with assays pending
• Main Vein below dyke further extended at southern end with two holes
Main Vein above dyke (Figure 2)
• CB-21-52: 3.7 meters of 9.41% Cu, 2.84 g/t Au and 36.5 g/t Ag – Extending Main Vein above dyke
along strike.
• Results pending for four other mineralized holes that will further expand the zone along strike
and at depth
“We are continuing to have success in expanding the Corner Bay deposit. These positive drill results from
three different areas of the deposit , as well as pending assays from the remaining of the 2021 drilling
program, are expected to further increase the mineral resources that will be reported in the upcoming PEA”
stated Ernest Mast, President and CEO of Doré Copper. “The connection of the Main Vein above the dyke
with the Lower D eep Lens is very significant. In addition , the intercept in hole CB -21-52 is the highest
copper equivalent grade recorded in the history of the deposit. Our 2022 drilling plans include approximately
40,000 meters of infill drilling at Corner Bay to upgrade the Inferred Resource to Indicated Resource for the
feasibility study that will commence after the completion of the PEA at the end of Q1 2022.
Corner Bay Drilling Program
The r esults reported today from t he 2021 drilling program ha ve successfully continued to expand the
copper-gold mineralization at Corner Bay in three areas of the deposit (Figure 3), bringing the total strike
length to over 1,100 metres. Of significance, the intercepts in holes CB-21-44, CB-21-45, CB-21-47, CB-
21-49 and CB-21-51 have effectively connected the Main Vein below the dyke to the Lower Deep Lens
(Figure 1 and Table 1). Two additional holes with assays pending have intersected copper mineralization.
These seven holes cover approximately 200 meters of strike length and 250 meters of vertical depth.

In addition, CB-21-39, CB-21-41 and CB-21-42 have expanded the Main Vein below the dyke to the south
by approximately 100 meters (at certain elevations ) from the October 2021 Mineral Resource Estimate
(Figure 1). The other holes (CB-21-39W1, CB-21-40, CB-21-43 and CB-21-46) drilled at the southern limit
of the Main Vein below the dyke did not intersect any significant mineralization and have limited the southern
extension of the Main Vein.
Hole CB-21-52 intercepted 3.7 meters of 9.41% Cu, 2.84 g/t Au , 36.5 g/t Ag and 890 ppm Mo
(molybdenum) (Figure 2 and Table 1). This hole has expanded the Main Vein above the dyke along strike
to the south by approximately 50 meters. This intercept is the highest copper equivalent grade recorded in
the history of the deposit.
The Corporation continues to obtain high molybdenum values in the intersections reported e.g. 682 ppm in
hole CB-21-45, 582 ppm in hole CB-21-49, and 890 ppm in hole CB-21-52. Over the course of 2022, Doré
Copper plans to initiate molybdenum recovery test work as part of the feasibility study.

Corner Bay Deposit
In the Mineral Resource estimate of October 6, 2021, t he Corner Bay deposit contains an Indicated
Resource of 2.66 Mt at 2.68% Cu and 0.26 g/t Au containing 157 million pounds of copper and 22,000
ounces of gold and an Inferred Resource of 4.54 Mt at 3.20% Cu and 0.27 g/t Au containing 320 million
pounds of copper and 39,000 ounces of gold , based on a cut-off grade of 1.3% Cu and a copper price of
US$3.75 per pound (refer to Technical Report dated November 10, 2021)2.
The Corner Bay deposit is hosted by the intrusive Lac Doré Complex on the southern flank of the
Chibougamau anticline. A regional north -northeastern diorite dyke also cuts the area. Several significant
shear zones oriented north -south and northwest -southeast have been identified in the area. The Corner
Bay area is characterized by copper porphyry style mineralization and by copper mineralization in shear
zones commonly associated with dykes related to the Chibougamau Pluton.
Drilling and Quality Control
The Company is using Miiken Drilling as the drilling contractor. Miiken 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 preparation was done at SGS Canada Inc. in Val-d’Or, Québec, and fire assay and ICP analysis
was done at SGS Canada Inc. in Burnaby, B .C. Samples were weighed, dried, crushed to 75% passing
2 mm, split to 250 g, and pulverized to 85% passing 75 microns. Samples were then fire assayed for Au
(50 g) and sodium peroxide fusion ICP-MS finish for 34 elements.
QA/QC is done in house by Doré Cop per Geologists with oversight from the Exploration Manager . The
check samples (blanks and standards – 4% of total samples with another 2% of core duplicates) that were
inserted into the sample batches are verified against their certified values and are dee med 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.
