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
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

- 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 8.65 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 Drilling Program
The results reported today from the 2021 drilling program have successfully continued to expand the copper-gold mineralization at
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
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.

Sample preparation was done at
QA/QC is done in house by Doré Copper 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 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.
