Bonterra Resources Inc. (TSXV: BTR) has obtained high-grade results from the ongoing infill drilling campaign at the Barry underground project in Quebec.
The company commenced a 125,000 m drill programme 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 (51 holes) 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.
Highlights include:
- 21.9 g/t Au over 4.4 m, including 158.5 g/t Au over 0.5 m in hole MB-22-541
- 7.5 g/t Au over 2.8 m, including 30.3 g/t Au over 0.6 m in hole MB-22-542
- 13.0 g/t Au over 3.7 m, including 49.7 g/t Au over 0.5 m and 6.7 g/t Au over 3.9 m, including 27.2 g/t Au over 0.7 m and 4.3 g/t Au over 5.8 m, including 24.2 g/t Au over 0.5 m in hole MB-22-547A
- 8.1 g/t Au over 4.0 m, including 44.5 g/t Au over 0.7 m in hole MB-22-548
“The ongoing infill drill programme at Barry is focused on the upper half of the underground deposit and continues to deliver high-grade results,” President and CEO, Marc André Pelletier, said.
“It is common to intercept more than one lens of mineralization in a single drill hole at Barry. For example, numerous high-grade intercepts are reported across six different lenses in drill hole MB 22-547A; highlighted by 13.0 g/t Au over 3.7 m in lens AB17; 6.7 g/t Au over 3.9 m in lens 800; and 4.3 g/t Au over and 5.8 m in lens H11.
“The company intends to continue infill drilling the Barry deposit next year with two diamond drills on surface at a rate of approximately 6,000 m per month.”
The ongoing infill drill programme 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 programme 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.
