Bonterra Intersects 6.4 g/t Au over 1.5 m, Including 18.9 g/t Au over 0.5 m at Moss

Val-d'Or, Quebec--(Newsfile Corp. - January 5, 2022) - Bonterra Resources Inc. (TSXV: BTR) (OTCQX: BONXF) (FSE: 9BR2) ("Bonterra" or the "Company") is pleased to provide new exploration results from the regional drilling campaign on the Moss property. The recent drilling results at Moss confirm the existence of high-grade gold mineralized veining in hole UB-21-15, which returned 6.4 g/t Au over 1.5 metres ("m"), including 18.9 g/t Au over 0.5 m.

Highlights:

• 6.4 g/t Au over 1.5 m, including 18.9 g/t Au over 0.9 m in hole UB-21-15
• 6.5 g/t Au over 1.5 m in hole UB-21-16

Pascal Hamelin, CEO commented: "These new high-grade exploration drilling results at Moss are very encouraging. Moss is an important regional target that was first drill tested by the Company in 2016. The discovery hole BE-16-09 returned 9.2 g/t Au over 2.2 m and 70.9 g/t Au over 2.6 m (see press release by a predecessor Company {Metanor Resources Inc.} dated October 31, 2016). Importantly, Moss is open along strike and at depth and situated between the Company's Barry deposit and the neighboring Windfall deposit. We currently plan to continue drill testing the Moss target area in the coming year."

The recent exploration drilling targeted the expansion of existing gold mineralization interpreted to trend northeast from some key historic high grade intersections in the Moss Center and Moss East areas. Moss historic values include 15.2 g/t Au over 1.3 m, 70.9 g/t Au over 2.6 m, and 102.2 g/t Au over 0.2 m (see SIGEOM document GM 70866 - MNRQ). Mineralization at Moss consists of a system sub-parallel mineralized veins trending northeast identified along a span of approximately three kilometres ("km") and remains open along strike and at depth.

Bonterra has drilled sixteen holes representing a total of 6,990 m at the Moss since September 2021. Partial results from twelve drill holes have been received thus far. Results from the remaining four holes are pending (See Figures 1, 2, 3, 4, 5 & 6 and Table 1).

Moss is centered on the northeast trending Mazeres fault along which several gold deposits and gold showings are spatially associated including the Barry and Windfall deposits. The Moss property is dominated by massive to pillowed basaltic to andesitic rocks with minor felsic volcanic rocks and tuffaceous horizons across the central and southeastern property area with local gabbroic to dioritic and felsic intrusions. Mineralization at Moss consists of a system of sub-parallel, shear hosted quartz-carbonate-chlorite veining and stockworks with minor sulfides which include pyrite, pyrrhotite, sphalerite and gold trending northeast and identified along a span of approximately three kms.

The Moss mineralized trend is subdivided into three areas: Moss West, Moss Center and Moss East. (See Figure 2)

Table 1: Significant mineralized intersections from drilling on the Moss Property

Notes:
1) The meterage represents the length of the drilled lengths.
2) True widths are estimated to be greater than 75% of the drill intersection length.
3) The mineralized intervals shown above use a 0.5 g/t Au cut-off grade.
4) Gold results obtained between 0.1 and 0.5 g/t Au are represented as anomalous values.
5) Gold results obtained below <0.1 g/t Au are represented as no significant values.

Quality Control and Reporting Protocols

The Moss drill core gold analyses are performed at the Company's Bachelor Mine analytical laboratory (the "Laboratory") and at Activation Laboratories Ltd. ("Actlabs"). 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.

Qualified Person

Boris Artinian, P.Geo., Chief Geologist of the Company oversees all exploration activities on the Moss property. Mr. Artinian is a qualified person as defined by National Instrument 43-101 ("NI-43-101"). Marc Ducharme, P.Geo. and Bonterra's Exploration Manager, has compiled and approved the information contained in this press release. Mr. Ducharme is a Qualified Person as defined by NI 43-101.
