Bonterra intersects 8.0 g/t Au over 12.1 m near surface northeast of the Barry Gold Deposit

Val-d’Or, QC – October 05, 2021 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce results from the ongoing drilling campaign at the Barry project. Recent drilling results expand upon the northeast sector of the Barry deposit near surface and at depth. The latest results obtained from 21 diamond drill holes are designed to expand the 2021 mineral resource estimate (“2021 MRE”) released in June (see press release dated June 23, 2021). Drilling highlights include 8.0 g/t grams-per-tonne gold (“g/t Au”) over 12.1 metres (“m”) in the near-surface zone AB8, approximately 75 m northeast of the 2021 MRE.

The Company is currently drilling at a rate of approximately 6,000 m per month, focused on expanding its main gold deposits highlighted within the recently released 2021 MREs.

Highlights include:

  • 8.0 g/t Au over 12.1 m, including 14.9 g/t Au over 3.7 m in MB-21-384
  • 1.8 g/t Au over 13.5 m, including 10.4 g/t Au over 1.0 m in MB-21-372
  • 2.5 g/t Au over 8.3 m, including 11.2 g/t Au over 1.7 m and 4.6 g/t Au over 3.5 m, including 25.6 g/t Au over 0.6 m in MB-21-382

Pascal Hamelin, CEO commented: “These near surface results, in particular in hole MB-21-384 substantiates our view that a strong mineralized potential exists at Barry from the recent exploration drilling which intercepted thick and continuous gold mineralization intervals near surface and within 200 m depth immediately adjacent to the 2021 MRE. More assays are pending from this same sector, and we look forward to receiving more diamond drill results from this area.”

The Barry drilling campaign is currently focused on the expansion of key gold mineralized zones around the 2021 MRE. Multiple diamond drill holes tested open pit potential to the northeast of the open pit resource shell in the 2021 MRE and followed up on deeper intercepts with holes MB-21-382 and MB- 21-383 (see press release dated March 1, 2021). High-grade gold mineralization occurring near-surface above open pit cut-off grade was intercepted at approximately 50 m northeast of the existing pit shell in the AB7 and AB8 zones and mineralization remains open to the east. Expansion drilling has confirmed the mineral continuity of several known H-Type zones and has intercepted new additional H-type zones north of the 1000 zone, returning high-grade intercepts at less than 200 m depth and laterally within 50 to 100 m of the existing resource along the 1000 zone. Follow-up drilling of this target area northeast of the Barry gold deposit will continue throughout the remainder of Q4 2021 and into Q1 2022 in order to better define their geometries. Drilling also continues to test extensions and outlining continued potential at depth of the H series mineralized structures to the southwest of Barry (Table 1, Figures 1, 2, 3, 4 and 5).

Barry Deposit Geology

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 vertical and remains open for expansion.

1) The meterage represents the length of the drilled lengths.

2) True widths are estimated to be greater than 70% of the drill intersection length.

3) The shown mineralized intervals listed are above 0.5 g/t Au.

4) Gold results obtained below 0.1 g/t Au are represented as no significant values

Quality Control and Reporting Protocols

The Barry project’s drill core gold analyses are performed at the Company’s Bachelor Mine analytical laboratory (the “Laboratory”). The Company employs a rigorous QA-QC analysis program that meets industry standards. The analyses are carried out by fire assay (A.A.) with atomic absorption finish. Blanks, duplicates, and certified reference standards are inserted into the sample stream to monitor the Laboratory’s performance. The Company’s QA-QC program requires that at least 10% of samples be analyzed by an independent laboratory. These verification samples are sent to ALS Minerals laboratory facility located in Val-d’Or, Quebec. The verifications show a high degree of correlation with the Laboratory’s results.
