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, QC – January 5, 2022 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF,

FSE: 9BR2) (“Bonterra” or the “ Company”) is pleased to provide new exploration results from the

regional drilling campaign on th e Moss property. The recent dr illing 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 fir st drill tested by the Company in 2016.

The discovery hole BE-16-09 retu rned 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 dr ill 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 consis ts 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 hol es representing a total of 6,99 0 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 Windf all deposits. The Moss property is

dominated by massive to pillowed basaltic to andesitic rocks wi th minor felsic volcanic rocks and

tuffaceous horizons across the central and southeastern property area with local gabbroic to dioritic and

felsic intrusions. Mineralizati on at Moss consists of a system of sub-parallel, shear hosted quartz-

carbonate-chlorite veining and st ockworks with minor sulfides w hich 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.

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.
