The 2021 drilling program totaled 41,063 meters in 43 holes (including wedge holes). Doré Copper is reporting today the results from five holes. The Corporation expects to receive assays for the remaining six holes of the program towards the end of February.
The drill results reported today have successfully expanded the copper-gold mineralization at
High-Grade Drilling Highlights
Main Vein above dyke (Figure 1)
- 3.9 meters of 8.03% Cu, 0.86 g/t Au, 42.1 g/t Ag, and 1,109 ppm Mo (hole CB-21-55)
- 4.2 meters of 6.18% Cu, 0.12 g/t Au, and 26.6 g/t Ag (hole CB-21-57) – extends mineralization 250 meters downdip from intercept 3.7 meters of 9.41% Cu, 2.84 g/t Au, 36.5 g/t Ag, and 890 ppm Mo in hole CB-21-52 (previously reported)
- Results pending from three other mineralized holes that will further expand the Main Vein above dyke along strike and at depth
Corner Bay Drilling Program
In the Main Vein above the dyke, today’s results from holes CB-21-53 (2.0 meters of 3.34% Cu and 15.6 g/t Ag), CB-21-55 (3.9 meters of 8.03% Cu, 0.86 g/t Au, 42.1 g/t Ag, and 1,109 ppm Mo), CB-21-57 (4.2 meters of 6.18% Cu, 0.12 g/t Au, and 26.6 g/t Ag) in combination with hole CB-21-52 (previously announced, 3.7 meters of 9.41% Cu, 2.84 g/t Au, 36.5 g/t Ag, and 890 ppm Mo) have defined a very high-grade copper zone of approximately 150 meters of strike length by 250 meters of vertical depth (Figure 1 and Table 1). This high-grade zone overlaps with the upper part of the Main Vein below the dyke and is still open down plunge.
In addition, holes CB-21-54 and CB-21-56 further confirmed that the mineralized area between the Main Vein below the dyke and the Deep Main Lens is continuous (Figure 2 and Table 1). This is another new area of 200 meters of strike length and approximately 300 meters of vertical extension that will be included the Mineral Resource update for the PEA.
The 2021 drilling program has successfully continued to expand the copper-gold mineralization at

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.
