Bonterra Resources Inc. announced the first results from the ongoing infill drilling campaign at the Barry underground project as well as the latest results of the open pit project, which are expected to be used for the grade interpolation of the mineralization at depth. The Company commenced a 125,000 metres ("m") drill program at the Barry underground deposit last August, which contains 0.5 million ounces of Measured and Indicated Mineral resources and 0.7 million ounces of Inferred Mineral resources, as stated in the last mineral resource estimate. To date, 15,900 m (33 holes) of infill drilling has been completed from the surface, mainly in the upper half of the Barry underground deposit. The Barry open pit drill program was designed to fill gaps in the drill spacing in and immediately around the pit shell from the 2021 MRE. Some holes have been extended below the pit scope to target high potential underground mineralization zones and will be used for the grade interpolation of the mineralization at depth. The results obtained from the in the pit mineralization depth range confirmed the strong southeast extension potential yielded by the H6 zone. Highlights include, from 25 to 40 m vertical depth, 10.7 g/t Au over 5.7 m including 96.5 g/t Au over 0.5 m and 8.7 g/t Au over 0.5 m in hole MB-22- 509A, 1.5 g/t Au over 8.8 m in hole MB-22-518 and 5.4 g/t Au over 2.8 m including 23.7 g/t Au over 0.6 m in hole MB-22-516 . The definition drilling program of the Barry underground project is designed to convert inferred resources
from the 2021 MRE in indicated resources by decreasing the drill spacing to 25 m. The program especially aims to delineate and expand high grades mineralization shoots identified in the 2021 MRE.
The results from the H1 zone, 200m below the surface, demonstrated the continuity of these mineralized shoots over more than 150 m. Best results includes: 12.8 g/t Au over 7.9 m including 29.1 g/t Au over 2.8 m in hole MB-22-433, 10.2 g/t Au over 4,0 m including 13.9 g/t Au over 1.1 m and 48.6 g/t Au over 0.5 m in hole MB-22-430 and 12.9 g/t Au over 3.3 m including 31.3 g/t Au over 1.1 m in hole MB-22- 539A. As winter conditions allow access to drill sites, the upcoming infill program will be focused on the prolific sub-vertical 800 Zone and its surrounding H-series zones. Preliminary results from accessible drill site returned good results in accordance with 2021 MRE block model prediction. Highlights include 2.5 g/t Au over 13.8 m including 5.3 g/t Au over 2.9 m in hole MB-22-534, and 9.5 g/t Au over 2.1 m in hole MB- 22-529A. In addition to these results the highest drill hole sample ever reported at the Barry project has returned 333.0 g/t Au over 0.5 m included in a mineralized interval of 79.9 g/t Au over 2.1 m in hole MB- 22-529A from a newly interpreted H series zone nearby the 800 zone.
