Val-d’Or, QC – May 30, 2023 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce more results from the now completed infill and expansion drilling campaign at the Barry underground project, which holds 0.5 million ounces of Measured and Indicated Mineral resources and 0.7 million ounces of Inferred Mineral resources according to the last mineral resources estimate (the “2021 MRE”, see press release dated June 23, 2021). The primary goal of this campaign was to convert mineral resources to a higher confidence category and enhance the interpretation and grade continuity of the mineralization, primarily in the upper section of the deposit. In total, 31,349 metres (“m”) (91 holes) of infill drilling has been completed from surface since August 2022. The Company has received assays for 89 holes so far, including the holes disclosed in this release (see press releases dated November 15, 2022, December 12, 2022, March 27, 2023, and May 1, 2023, for previously released holes). To date, 1,619 samples are pending results.

Highlights include:

• 8.2 g/t Au over 8.2 m, including 16.6 g/t Au over 3.4 m and 54.5 g/t Au over 0.5 m in holeMB-23-593A
• 5.0 g/t Au over 7.2 m, including 23.0 g/t Au over 0.7 m and 16.2 g/t Au over 0.6 m in holeMB-23-599
• 7.2 g/t Au over 3.7 m, including 30.0 g/t Au over 0.5 m in hole MB-23-601A
• 6.4 g/t Au over 2.9 m, including 16.9 g/t Au over 1.0 m in hole MB-23-611

Operational Updates

In addition to the cost saving initiatives announced in November 2022 and March 2023 (see press releases dated November 23, 2022, and March 6, 2023), the Company implemented a new working schedule at the Barry site in April 2023 and expects to reduce fixed camp costs by 50% or approximately $0.5 million (“M”) in 2023. Also, the Company received proceeds of $0.4 M in Q1 2023 from the rental of the Bachelor camp during the construction of the proposed Kuikuhaacheu hydroelectric power transmission line from the Waswanipi substation to the Windfall gold project, which is approximately 15 kilometers (“km”) from Bonterra’s Barry and Gladiator deposits. More revenue is expected for the rest of the year. Finally, the Company is currently undertaking the cleaning of the Bachelor Mill to recover the gold trapped in the circuit from past production activity. This work is expected to take place in the ensuing months and the revenue generated is expected to support the Company’s exploration activities.

Marc André Pelletier, President and CEO commented: “Several revenue-generating and costcutting initiatives are currently underway to bolster our operations and facilitate our renewed focus on exploration in the Urban-Barry camp. We share the same belief as our neighbors, Gold Fields and Osisko Mining, in the untapped potential for new discoveries within the Urban-Barry camp. The findings announced today provide further confirmation of the Barry deposit’s depth potential, with the 800 Zone remaining open down plunge to the East. We are pleased with the progress of our ongoing drill campaigns at Panache South and Barry North-East, following our updated work schedule, and we thank our employees for their flexibility.”

Exploration Updates

The Company has allocated one drill rig to its Barry North-East regional exploration program, which consists of eleven drill holes covering 3,200 m (See Figure 3). This program targets induced polarization anomalies along the Mazeres fault corridor, located three km to the northeast of the Barry deposit. So far, four drill holes covering 1,654 m have been completed.

The Company also commenced a 3,500 m exploration and follow-up drill program at the Panache South target area. The program is currently testing targets North of historical showing of 12.9 g/t Au over 0.5 m and 3.2 g/t Au over 0.4 m as well as showings from the 2021 drill campaign where significant gold mineralization was intersected such as 5.5 g/t Au over 1.5 m, including 16.2 g/t Au over 0.5 m, 23.1 g/t Au over 2.3 m, including 62.3 g/t Au over 0.8 m, and 30.6 g/t Au over 1.5 m, including 91.4 g/t Au over 0.5 m from shear-hosted quartz carbonate vein systems (Panache South drill hole references in this paragraph are from the Company’s press release dated March 1, 2022). So far, two drill holes totalling 909 m have been completed.

Diamond Drilling Results Highlights:

The infill drill program at the Barry underground project was designed to convert the Inferred resources from the 2021 MRE into Indicated resources by decreasing the drill spacing to 25 m and to expand the mineralization in the sub-vertical 800 Zone at depth. The results presented in this release keep on defining the high grade ore shoots between 100 and 200 m below the surface and better delineate the mineralization in the lesser drilled portion of the 800 Zone around 250 m below the surface.

The latest infill drilling results from the 800 Zone demonstrate the continuity of the mineralization. Hole MB-23-593A returned results of 8.2 g/t Au over 8.2 m including 54.5 g/t Au over 0.5 m, hole MB 23-599 returned 5.0 g/t Au over 7.2 m including 16.2 g/t Au over 0.6 m, as well as hole MB 23-601A returned 7.2 g/t Au over 3.7m including 30 g/t Au over 0.5m and finally the MB 23-611 returned 6.4 g/t Au over 2.9 m including 16.2 g/t Au over 2.0 m. All the results confirm the plunge of the gold trend, its extension at depth and the potential to increase the mineral resources for the 800 Zone.

The Barry North-East and the Panache South properties are located on the west portion of the Urban-Barry camp, in the Macho mafic volcanic formation, where the Barry deposit and Moss showings occur along the Mazeres fault system striking N60 toward the Osisko Mining’s Windfall deposit. The Panache showing located in the northeast portion of the area occurs along the Milner fault which also hosts the Fox and Fox West Zones owned by Osisko Mining.

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 from 50 to 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 sulphides within shear zones and veins with local visible gold. The Barry deposit has been delineated over 1.4 km along strike and 700 m below surface and remains open for expansion.

Quality Control and Reporting Protocols

The Barry project’s drill core gold analyses are performed at Actlabs located in Ste-GermaineBoulé, Quebec. The external laboratories employ a rigorous QA-QC analysis program that meets industry standards. The analyses are carried out by fire assay (A.A.) with atomic absorption finish and with gravimetric finish for assay above 10 g/t Au at Actlabs and AGAT laboratories. 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 5% 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.

Val-d’Or, QC – May 1, 2023 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce more results from the now completed infill and expansion drilling campaign at the Barry underground project, which holds 0.5 million ounces of Measured and Indicated Mineral resources and 0.7 million ounces of Inferred Mineral resources according to the last mineral resources estimate (the “2021 MRE”, see press release dated June 23, 2021). The primary goal of this campaign was to convert mineral resources to a higher confidence category and enhance the interpretation and grade continuity of the mineralization, primarily in the upper section of the deposit. In total, 31,349 metres (“m”) (91 holes) of infill drilling has been completed from surface since August 2022. The Company has received assays for 80 holes so far, including the holes disclosed in this release (see press releases dated November 15, 2022, December 12, 2022, and March 27, 2023, for previously released holes).

Highlights include:

• 6.2 g/t Au over 7.7 m, including 12.8 g/t Au over 2.8 m and 13.0 g/t Au over 0.5 m inhole MB-23-598
• 26.3 g/t Au over 1.2 m, including 38.1 g/t Au over 0.7 m in hole MB-23-600
• 4.5 g/t Au over 4.2 m, including 20.3 g/t Au over 0.5 m in hole MB-23-592
• 1.6 g/t Au over 6.0 m, including 2.2 g/t Au over 2.0 m in hole MB-23-613

Marc André Pelletier, President and CEO commented: “The results reported today are encouraging for many reasons. Holes MB-23-598, MB-23-600 and MB-23-592 intercepted mineralisation consistent with the high-grade ore shoots in the 800 Zone. Meanwhile, hole MB-23-613 confirmed the extension of mineralization from the 800 Zone approximately 150 m further than the known mineralized envelope and suggests that there is continuity of the mineralization at depth. With the conclusion of the winter drill program at Duke, we have started a greenfield exploration program at Barry North-East and a more focused program at Panache South. Bonterra remains committed to continuing to explore the Urban-Barry camp where several million ounces of gold have already been discovered to date.”

Exploration Updates

The drill program at the Duke property (“Duke”), a joint venture with Osisko Mining Inc. (“Osisko”), consisting of 10 holes covering 3,387 m has been completed on schedule (see press releases dated March 6, 2023, and March 27, 2023). Also, a short drill program of two holes totaling 706 m was completed just before the spring thaw at the Nelligan property near the Bachelor Mill Complex.

Following the completion of the Duke and Nelligan programs, the Company has allocated one drill rig to its Barry North-East regional exploration program, which consists of 11 drill holes covering 3,200 m. This program targets polarization anomalies along the Mazeres fault corridor, located 3 kilometers (“km”) to the northeast of the Barry deposit (See Figure 3). So far, three drill holes covering 969 m have been completed.

The Company will also commence a 3,500 m exploration and follow-up drill program at the Panache South target. The area includes the historical Panache South showing with 12.9 g/t Au over 0.5 m and 3.2 g/t Au over 0.4 m. In 2021, the Company drilled 4,383 m at the Panache South target and intersected significant gold mineralization, including 5.5 g/t Au over 1.5 m, including 16.2 g/t Au over 0.5 m, 23.1 g/t Au over 2.3 m, including 62.3 g/t Au over 0.8 m, and 30.6 g/t Au over 1.5 m, including 91.4 g/t Au over 0.5 m from shear-hosted quartz carbonate vein systems (Panache South drill hole references in this paragraph are from the Company’s press release dated March 1, 2022).

Diamond Drilling Results Highlights:

The infill drill program at the Barry underground project was designed to convert the Inferred resources from the 2021 MRE into Indicated resources by decreasing the drill spacing to 25 m and to expand the mineralization in the sub-vertical 800 Zone at depth. The results presented in this release demonstrate the predictability of the 800 Zone geology model and highlight that the mineralization remains open at depth, following the well-defined high-grade ore shoots.

The infill drill results from the 800 Zone continue to demonstrate a high potential for high-grade mineralization, as evidenced by intersections of 6.2 g/t Au over 7.7 m, including 12.8 g/t Au over 2.8 m and 13.0 g/t Au over 0.5 meters in hole MB-23-598, 26.3 g/t Au over 1.2 meters, including 38.1 g/t Au over 0.7 m in hole MB-23-600, and 4.5 g/t Au over 4.2 m, including 20.3 g/t Au over 0.5 m in hole MB-23-592.

Furthermore, preliminary results from three holes drilled 150 meters down plunge of the 800 Zone have returned 1.6 g/t Au over 6.0 m, including 2.2 g/t Au over 2.0 m in hole MB-23-613, confirming the mineralization remains open at depth and allow to target new high-grade shoots down dip of the orebody to the east.

The Barry North-East and the Panache South properties are located on the west portion of the Urban-Barry camp, in the Macho mafic volcanic formation, where the Barry deposit and Moss showings occur along the Mazeres fault system striking N60 toward the Osisko’s Windfall deposit. The Panache showing located in the northeast portion of the area occurs along the Milner fault which also hosts the Fox and Fox West Zones owned by Osisko.

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 from 50 to 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 sulphides within shear zones and veins with local visible gold. The Barry deposit has been delineated over 1.4 km along strike and 700 m below surface and remains open for expansion.

As of now, six of ten holes have been drilled, and the drilling activities are tracking on schedule (see press release dated March 6, 2023). The drill results are expected to be released upon completion of the program. 

The drill program at Duke is part of the Company’s renewed focus on regional exploration at a rate of approximately 1,400 m per month in the Urban-Barry and Bachelor camps. 

Marc André Pelletier, President and CEO commented: “The exploration program at Duke in collaboration with our joint venture partner Osisko is progressing well. Duke is located adjacent to the Company’s Gladiator deposit and Osisko’s Windfall gold project, as well as the Barry deposit to the west. Together, these three deposits contain a significant gold resource of over 10 million ounces, and the Company remains focused on exploring the Urban-Barry camp this year. Following the completion of the infill drill program at the Barry underground project, the Company plans to update the geological model of the underground deposit to determine the next steps for the Barry deposit. Additionally, an exploration program will soon take place at the Barry Northeast and Panache properties to test high potential exploration targets.” 

Diamond Drilling Results Highlights: 

Figure 1 – Barry Project –Surface Plan, Holes, and Highlights Location 

The completed infill drill program of the Barry underground project was 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 potential of increasing quantity and continuity of the underground mineralization. 

Figure 2 – Barry Project – Composite Long Section of the Barry Deposit Looking Northwest 

Infill drilling in the 800 zone continue to delineate and increase the length and continuity of the high-grade shoots. Results like 34.7 g/t Au over 2.4m including 72.0 g/t Au over 1.1 m in hole MB-22-560A, 16.3 g/t Au over 2.8 m including 26.6 g/t Au over 1.7 m in hole MB-22-585 and 17.7 g/t Au over 3.2 m including 30.1 g/t Au over 1.8 m in hole MB-23-594 enhance the potential of high grade continuous mineralized shoots in the 800 zone (Figure 3). Assays from 17 holes drilled in the zone 800 during winter are pending. 

Figure 3 – Barry Project – Long Section, Zone 800 Looking Northwest 

Infill Drilling into the H6/D4 moderate south dipping self-intersecting zones helped to better constrain the high-grade mineralization highlighted by the 2021 MRE. Infill drilling continues to highlight the continuity of high-grade shoots through the mineralized shears. Results as 9.0 g/t Au over 9.2 m including 21.7 g/t Au over 2.0 m in hole MB-22-578, 5.6 g/t Au over 6.3 m including 10.7 g/t Au over 2.0 m in hole MB-22-575 and 4.6 g/t Au over 7.7 m including 9.2 g/t Au over 2.5 m and 11.5 g/t Au over 0.7 m in hole MB-22-554 enhance the 300 m long continuity of large high grade shoots in zone H6 (Figure 4). 

Figure 4 – Barry Project – Long Section, Zone H6 and D4 Looking Northwest 

Infill drilling in poorly defined H18 zone following the high-grade shoots has successfully intercepted high mineralization were predicted. Drill results highlight the potential for a 300 m long mineralized shoot in the shear zone located 20 m beneath the H6 shear. Demonstration is made by results in hole MB-22-565A with 6.4 g/t Au over 4.0 m including 13.2 g/t Au over 1.2 m, hole MB-22-564 returning 3.0 g/t Au over 10.4 m including 13.4 g/t Au over 1.1 m hole MB-22-575 intercepting 4.7 g/t Au over 8.1 g/t Au including 11.6 g/t Au over 1.5 m and hole MB-22-578 with 10.7 g/t Au over 1.5 m.

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 from 50 to 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 kilometre along strike and 700 m below surface and remains open for expansion.

Val-d’Or, QC – March 6, 2022 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) a Canadian gold exploration company with a large portfolio of advanced exploration assets anchored by a central milling facility in northern Quebec, Canada, provides the following operational updates:

Inflation and further Cost Saving Initiatives

In response to the challenging inflationary pressures related to project development, specifically in northern Quebec, the Company continues to significantly reduce its fixed expenses. In addition to the cost saving initiatives announced in November 2022 (see press release dated November 23, 2022), the Company has completed the transition from processing most assays at its wholly owned laboratory to an external laboratory.

Bonterra has also entered into an agreement for the rental of the Bachelor camp with the main contractor in charge of the construction of the proposed Kuikuhaacheu hydroelectric power transmission line from the Waswanipi substation to the Windfall gold project. The Company is also evaluating other cost-saving initiatives.

Infill Drill Program at Barry

On September 7, 2022, the Company began a 125,000 metres (“m”) drill program at the Barry underground deposit, which holds 0.5 million ounces of Measured and Indicated Mineral resources and 0.7 million ounces of Inferred Mineral resources according to the last mineral resources estimate (the “2021 MRE”, see press release dated June 23, 2021). To date, 31,350 m of infill drilling (107 holes) has been completed, mainly in the upper half of the deposit.

The challenging inflationary pressures related to project development have also led the Company to pause the infill drill program and engineering work related to the Barry underground deposit. However, geological interpretation work will continue at both the Barry and Gladiator deposits throughout the year.

The two rigs formerly used for infill drilling will now be utilized for a targeted regional exploration program across the Company’s 38,050 hectares land package, averaging about 1,400 m per month. This drill program will be focused primarily in the Urban-Barry property and to a lesser extent, the Bachelor property. An airborne geophysical survey will also be conducted at Bachelor to identify optimal exploration targets.

Renewed Focus on Regional Exploration

The Company is pleased to announce the launch of an exploration program at the Duke property (“Duke” or the “Property”), a joint venture with Osisko Mining Inc. (“Osisko” or the “Partner”). The Property consists of 81 mineral claims totaling 3,590 hectares, adjacent to the Company’s Gladiator deposit and Osisko’s Windfall gold project (Figure 1). Bonterra and Osisko are joint venture partners with a 70% and 30% working interest, respectively, to explore Duke (see press release dated July 13, 2021). This program is part of the Company’s renewed focus on regional exploration.

The exploration program for Duke comprises ten holes, totaling 3,300 m in the corridor of volcanic rocks bounded by the Rouleau and St Çyr faults which contains the lac Rouleau deposit that comprises Zones 18, 17 and 14. Seven holes will be drilled northeast of the Lac Rouleau deposit, where the litho-structural trend abruptly shifts from N80 to N45 degrees related to the emplacement of intrusive bodies creating potential traps for mineralizing fluids, while three holes will be drilled on the west side of the Lac Rouleau deposit, directly south of the Rouleau fault to test N60 degrees trending structures that connects the St Çyr and Rouleau faults (Figure 2).

Known gold mineralization at Duke are, like the Barry and Gladiator deposits, controlled by N60 to N80 degrees trending shear zones located on, or proximal to major regional litho-stratigraphical contacts such as the Rouleau or the St Çyr faults. Gold occurrences are often associated with the lithological complexity created by mafic to felsic intrusions. It is to be noted that the Gladiator deposit contains 0.4 million ounces of Measured and Indicated Mineral resources and 1.0 million ounces of Inferred Mineral resources, as stated in the 2021 MRE.

Marc André Pelletier, President and CEO commented: “As part of our ongoing commitment to cost reduction and optimizing capital allocation for the benefit of our shareholders, we have made the decision to pause the infill drilling campaign at the Barry deposit. We are mindful of the challenging market conditions faced by junior mining companies like Bonterra, as well as inflationary pressures such as higher energy costs for underground operations without access to the hydroelectric grid. We are pleased to note the forthcoming construction of the hydroelectrical transmission line near our projects by Miyuukaa Corporation, and we are contributing to this project by providing a camp to the main contractor. In addition, we are excited to launch a regional exploration program in collaboration with Osisko as part of our joint venture on Duke, with the goal of targeting untested ground along the Rouleau fault using two drill rigs. This program supports our view of the significant exploration potential in the Urban-Barry camp.”

Geology

La propriété Duke couvre trois unités litho-stratigraphiques de la ceinture de roches vertes Urban-Barry. La formation de Lacroix composée de roches volcaniques ultramafiques à mafiques qui encaisse le gîte Gladiator, la formation de Chanceux composée majoritairement d’unités volcano-sédimentaires et de roches volcaniques mafiques qui abrite l’indice Cominco, l’indice #4 et l’indice Centaur ainsi que des occurrences de minéralisations sulfurées volcanogènes comme l’indice Lac Morissette (Quesnel), enfin la formation Macho composée de volcanites mafiques avec des centres volcaniques felsiques qui encaissent les gîtes Barry et Windfall. Ces trois unités litho-stratigraphiques sont délimitées par deux failles majeures orientées N60 degrés sub-verticales : la faille Barry, sur laquelle le gîte de Gladiator est situé, entre la formation Lacroix et Chanceux; la faille de St Çyr se produit au contact entre les formations de Chanceux et de Macho où le gîte du Lac Rouleau est situé. La faille Rouleau parallèle aux failles St Cyr et Barry, délimitent un fort contraste magnétique dans la formation Macho créant une zone très prometteuse pour découvrir de nouveaux gîtes. La minéralisation sur la propriété Duke varie en style. Le gîte du lac Rouleau consiste en une diorite fortement altérée et cisaillée au contact entre des coulées mafiques et des tufs intermédiaires avec une minéralisation en pyrite et des veines de quartz fumé. Les indices Cominco, indice #4 et Centaur, encaissés dans un gabbro et son contact cisaillé avec les roches volcaniques, sont composés de brèches de quartz blanc associées à une forte altération carbonatée en séricite et fuchsite avec une pyritisation mineure. L’indice du Lac Morissette (Quesnel) est formé par une lentille de sulfures massifs avec un porphyre de quartz feldspaths. Le programme de forage d’exploration est conçu pour tester de nouvelles cibles le long du corridor entre les failles St Cyr et Rouleau ainsi que pour tester l’extension le long de la minéralisation connue.

Val-d’Or, QC – December 12, 2022 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce more results from the ongoing infill drilling campaign at the Barry underground project. The Company commenced a 125,000 metres (“m”) 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 (the “2021 MRE”, see press release dated June 23, 2021). 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

Marc André Pelletier, President and CEO commented: “The ongoing infill drill program at Barry is focused on the upper half of the underground deposit and continues to deliver high-grade results. 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.”

Diamond Drilling Results Highlights:

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 are shown on Figure 2.

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 (Figures 3 and 4).

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 below surface and remains open for expansion.

Val-d’Or, QC – November 23, 2022 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) a Canadian gold exploration company with a large portfolio of advanced exploration assets anchored by a central milling facility in northern Quebec, Canada, provides the following operational updates:

Cost Saving Initiatives

The Company is pleased to announce that it has completed the process of putting the underground infrastructure at the Bachelor-Moroy deposit under long-term care and maintenance (see press release dated September 7, 2022). All useable equipment, spare parts and consumables have been relocated to surface safely. Flooding of the underground infrastructure is in progress and the site remains in compliance with all applicable governmental regulations.

With respect to permitting and considering the aforementioned changes, the Company has revised the scope of the expansion for the Bachelor Mill Complex and reports that it has submitted answers to the second stage of questions to COMEX (Environmental and Social Impact Review Committee). The revised expansion project considers a daily throughput of 1,800 tonnes per day (“tpd”) (compared to 2,400 tpd in the original expansion request) and maintains the same capacity for the tailings management facility of an additional 8 million tonnes. At the revised throughput of 1,800 tpd, the Company may be eligible to permit the expansion through a more streamlined process. The Company intends to continue to work in close collaboration with the regulatory authorities and local stakeholders throughout the permitting process.

Pre-Feasibility Study (“PFS”) Update

The Company has undertaken a PFS on the Barry open pit project following the release of a positive preliminary economic assessment (“PEA”) earlier this year (see press release dated June 13, 2022). Several technical milestones have been achieved since the commencement of the PFS including 25,000 meters (“m”) of infill drilling at the open pit deposit and geochemistry, hydrogeology and geotechnical analysis at both the Barry and Bachelor Mill Complex.

Although a significant amount of progress on technical matters has been made as part of the PFS, the inability to receive timely and reasonable quotes from mining contractors, suppliers and other service providers has created a challenging environment to adequately assess the economics of the Barry open pit project. This is in addition to significant cost escalation that is prevalent throughout the mining sector. This has led the Company to re-evaluate the development plan at Barry. Specifically, the Company is planning to first complete an infill drilling program on the upper half (above 300 m elevation) of the underground portion of the Barry deposit to determine whether the higher-grade mineralization from the underground, combined with a likely larger scale operation, generates a more economically robust development.

Two drill rigs are presently in operation at Barry at a rate of 6,000 m per month (see press release dated November 15, 2022). The drilling is focused on the upper half of the underground deposit at Barry. To date, 15,900 m of infill drilling has been completed targeting the underground.

Marc André Pelletier, President and CEO commented: “Challenges in preparing the PFS as a result of inflationary pressures on energy, equipment, and labour costs are affecting the entire mining industry, especially in northern Quebec. Rather than join the ranks of mining companies that are developing assets in this challenging environment, Bonterra has decided to re-evaluate the development plan at Barry. Importantly, all the technical work carried out to date is expected to form a solid foundation for future mine development and especially for advancing the permitting.

With the Bachelor-Moroy deposit underground infrastructure under long-term care and maintenance, the Company is on track to reduce its maintenance costs and expects to reallocate those financial resources towards advancing the development of the Barry project. Other cost saving initiatives are also being considered to further reduce costs.’’

Cautionary and Forward-Looking Statements

This press release contains “forward-looking information” that is based on Bonterra’s current expectations, estimates, forecasts and projections. This forward-looking information includes, among other things, statements with respect to Bonterra’s exploration and development plans and placing the Bachelor-Moroy deposit under long-term care and maintenance. The words “will”, “anticipated”, “plans” or other similar words and phrases are intended to identify forward-looking information. This forward-looking information includes namely information with respect to the planned exploration programs and the potential growth in mineral resources. Exploration results that include drill results on wide spacings may not be indicative of the occurrence of a mineral deposit and such results do not provide assurance that further work will establish sufficient grade, continuity, metallurgical characteristics and economic potential to be classed as a category of mineral resource. The potential quantities and grades of drilling targets are conceptual in nature and, there has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the targets being delineated as mineral resources. Forward-looking information is subject to known and unknown risks, uncertainties and other factors that may cause Bonterra’s actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forwardlooking information. Such factors include but are not limited to: uncertainties related exploration and development; the ability to raise sufficient capital to fund exploration and development; changes in economic conditions or financial markets, environmental and other judicial, regulatory, political and competitive developments; technological or operational difficulties or inability to obtain permits encountered in connection with exploration activities; and labour relations matters. This list is not exhaustive of the factors that may affect our forward-looking information. These and other factors should be considered carefully, and readers should not place undue reliance on such forward-looking information.

Val-d’Or, QC – November 15, 2022 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce the first results from the ongoing infill drilling campaign at the Barry underground project as well as the latest results of the open pit project, which are expected to be used for the grade interpolation of the mineralization at depth. The Company commenced a 125,000 metres (“m”) 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 (the “2021 MRE”, see press release dated June 23, 2021). To date, 15,900 m (33 holes) of infill drilling has been completed from the surface, mainly in the upper half of the Barry underground deposit.

Highlights include:

• 79.9 g/t Au over 2.1 m, including 333.0 g/t Au over 0.5 m in hole MB-22-529A
• 12.8 g/t Au over 7.9 m, including 29.1 g/t Au over 2.8 m in hole MB-22-433
• 10.7 g/t Au over 5.7 m, including 96.5 g/t Au over 0.5 m and 8.7 g/t Au over 0.5 m in hole MB-22-509A
• 10.2 g/t Au over 4.0 m, including 13.9 g/t Au over 1.1 m and 48.6 g/t Au over 0.5 m in hole MB-22-430
• 12.9 g/t Au over 3.3 m, including 31.3 g/t Au over 1.1 m in hole MB-22-539A

Marc André Pelletier, President and CEO commented: “We are pleased with the recent results of the ongoing infill drilling campaign for the underground deposit at Barry. MB-22-529A drill hole results of 333.0 g/t over 0.5 m represents the highest reported interception ever at the Barry project. This campaign fits well with our strategy of moving the Barry asset toward a production re-start. Considering the magnitude of the underground mineral resources, the deposit has the potential to become a long-lived operation and the Company intends to further define its potential. Drilling at Barry will continue with two drill rigs on site. Also, the pre-feasibility study (“PFS”) on the Barry open pit project is at an important juncture and an update is expected before year end.”

Diamond Drilling Results Highlights:

The Barry open pit drill program was designed to fill gaps in the drill spacing in and immediately around the pit shell from the 2021 MRE. Some holes have been extended below the pit scope to target high potential underground mineralization zones and will be used for the grade interpolation of the mineralization at depth. The results obtained from the in the pit mineralization depth range confirmed the strong southeast extension potential yielded by the H6 zone. Highlights include, from 25 to 40 m vertical depth, 10.7 g/t Au over 5.7 m including 96.5 g/t Au over 0.5 m and 8.7 g/t Au over 0.5 m in hole MB-22-509A, 1.5 g/t Au over 8.8 m in hole MB-22-518 and 5.4 g/t Au over 2.8 m including 23.7 g/t Au over 0.6 m in hole MB-22-516 (figure 3).

The definition drilling program of the Barry underground project is designed to convert inferred resources from the 2021 MRE in indicated resources by decreasing the drill spacing to 25 m. The program especially aims to delineate and expand high grades mineralization shoots identified in the 2021 MRE. The results from the H1 zone, 200m below the surface, demonstrated the continuity of these mineralized shoots over more than 150 m. Best results includes : 12.8 g/t Au over 7.9 m including 29.1 g/t Au over 2.8 m in hole MB-22-433, 10.2 g/t Au over 4,0 m including 13.9 g/t Au over 1.1 m and 48.6 g/t Au over 0.5 m in hole MB-22-430 and 12.9 g/t Au over 3.3 m including 31.3 g/t Au over 1.1 m in hole MB-22-539A (figure 4).

As winter conditions allow access to drill sites, the upcoming infill program will be focused on the prolific sub-vertical 800 Zone and its surrounding H-series zones. Preliminary results from accessible drill site returned good results in accordance with 2021 MRE block model prediction. Highlights include 2.5 g/t Au over 13.8 m including 5.3 g/t Au over 2.9 m in hole MB-22-534, and 9.5 g/t Au over 2.1 m in hole MB-22-529A. In addition to these results the highest drill hole sample ever reported at the Barry project has returned 333.0 g/t Au over 0.5 m included in a mineralized interval of 79.9 g/t Au over 2.1 m in hole MB-22-529A from a newly interpreted H series zone nearby the 800 zone (figure 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 kilometre along strike and 700 m vertical and remains open for expansion.

Corporate Updates

The Company is also pleased to announce that it has retained PI Financial Corp. (“PI”) to provide marketing services in accordance with TSX Venture Exchange (“TSX”) policies. PI will trade the securities of Bonterra on the TSX for the purposes of maintaining an orderly market. In consideration of the services provided by PI, the Company will pay PI a monthly cash fee of $5,000 for a minimum term of three months and renewable thereafter. Bonterra and PI are unrelated and unaffiliated entities. PI will not receive shares or options as compensation. The capital used for market making will be provided by PI.

In addition, the Company also announces that at the annual and special meeting of its shareholders held on June 22, 2022 (the “Meeting”), the shareholders approved the adoption of Bonterra’s new omnibus equity incentive plan (the “Omnibus Plan”) and reserved common shares of Bonterra (“Common Shares”) for issuance under the Omnibus Plan. The Omnibus Plan allows the Company to issue stock options, restricted share units, performance share units and deferred share nits (the “Awards”). The Omnibus Plan is a “rolling up to 10% plan” (as that term is used by the TSX) and replaces the Company’s previous rolling 10% stock option plan. The maximum aggregate number of Common Shares that may be reserved for issuance under the Omnibus Plan at any point in time is 10% of the outstanding Common Shares in the capital of the Company at the time of the grant of an Award and the Common Shares reserved and currently available for issuance under the Omnibus Plan is 12,619,550 Common Shares (such number being equal to approximately 10% of the issued and outstanding Common Shares). On November 24, 2021, the TSX adopted a new policy governing security-based compensation (the “New Policy 4.4”). In accordance with the New Policy 4.4, the Company has adopted a number of these amendments in the Omnibus Plan. These changes include allowing option holders to exercise options on a “cashless exercise” or “net exercise” basis, as now expressly permitted by the New Policy 4.4. “Cashless exercise” is a method of exercising stock options in which a securities dealer loans funds to the option holder or sells the same shares as those underlying the option, prior to or in conjunction with the exercise of options, to allow the option holder to fund the exercise of some or all of their options. “Net exercise” is a method of option exercise under which the option holder does not make any payment to the issuer for the exercise of their options and receives on exercise a number of shares equal to the intrinsic value (current market price less the exercise price) of the option valued at the current market price. Under the New Policy 4.4, the current market price must be the 5-day volume weighted average trading price prior to option exercise. “Net exercise” may not be utilized by persons performing investor relations services. The Omnibus Plan, is further described in the Company’s information circular, a copy of which can be found on the Company’s SEDAR profile at www.sedar.com.
