Bonterra Resources Inc. announced more results from the ongoing infill drilling campaign at the Barry underground project. The Company commenced a 125,000 metres 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, 21,800 m of infill drilling has been completed from the surface, mainly in the upper half of the Barry underground deposit. Since the previous release dated November 15, 2022, assays from 11 holes have been received. Highlights from these assays are presented in the present release. The ongoing infill drill program of the Barry underground project is designed to convert the Inferred resources from the 2021 MRE into Indicated resources by decreasing the drill spacing to 25 m. The program especially aims to delineate and expand high-grade mineralized shoots identified in the 2021 MRE. Results from recent assays, including those in this press release, underscore the economic potential of the underground mineralization with high-grade intersections between 100 m and 300 m below surface in well know mineralized lenses. For example, MB-22-541 reported 21.9 g/t Au over 4.4 m, including 158.5 g/t Au over 0.5 m in H8 Zone, 200 m below surface; MB-22-548 returned 8.1 g/t Au, over 4.0 m, including 44.5 g/t Au over 0.7 m from the H3 Zone, 300 m below the surface; MB-22-547A
returned 4.3 g/t Au over 5.8 m, including 24.2 g/t Au over 0.5 m from H11 Zone, 350 m below surface; 13.0 g/t over 3.7 m, including 49.7 g/t Au over 0.5 m 100 m below the surface from AB 17 Zone; and lastly MB-542 reported 7.5 g/t Au over 2.8 m, 100 m below the surface from the AB 01 Zone. These strong intercepts as well as certain intercepts highlighted in press releases throughout 2022. The sub-vertical 800 Zone and its surrounding H-series zones continue to provide high-grade drilling results as highlighted by hole MB-22-547A returning 6.7 g/t Au over 3.9 m, including 27.2 g/t Au over 0.7 m and hole MB-22-542 returning 2.6 g/t Au over 4.2, including 14.5 g/t Au over 0.5 m. The Barry gold deposit is characterized by three dominant sets of structures, all dipping to the southeast. The sub-vertical shear zones and the H-Series shear zones dipping 25 to 40 degrees are hosted within intermediate to mafic volcanics and tuffs with local felsic intrusions. Contact zones dip at 50-65 degrees along the lower and upper contacts of the D1, D2 and D3 felsic intrusions with mafic volcanics. Gold mineralization is associated with disseminated sulfides within shear zones and veins with local visible gold. The Barry deposit has been delineated over 1.4 kilometres along strike and 700 m below surface and remains open for expansion.
