Bonterra Announces Encouraging Initial Drill Results at Moss Target of Phoenix JV with Osisko Mining

Val-d’Or, QC – April 15, 2024 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce encouraging drill results and an update on the ongoing drilling program on the Phoenix JV (formerly known as the UrbanBarry Property) (the “Project”). The Project is under a definitive earn-in and joint venture agreement (the “Agreement”) with Osisko Mining Inc. (“Osisko Mining”). Under the Agreement, Osisko Mining has the right to acquire up to a 70% interest in the Project by spending $30 million in work expenditures, with a minimum spending commitment of $10 million per year over a threeyear period (see press release dated November 28, 2023 for more details).

To date, approximately 20,000 meters (“m”) have been drilled on the Project and exploration efforts are on track to exceed the minimum spending commitment of $10 million per year outlined in the Agreement. There are currently five drill rigs on the Moss target, while one is dedicated to the Barry northeast target (see Figure 1).

The first drill results at the Moss target, located five kilometers (“km”) southwest of the multimillion ounce Windfall Gold deposit, have confirmed similarities with the geological character of the high-grade Lynx Zone along the Mazères Fault that extends towards the Moss target.

Highlights at Moss Target Include:

  • 5.18 g/t Au over 3.3 m, including 16.75 g/t Au over 1.0 m and,3.19 g/t Au over 2.9 m, including 12.70 g/t Au over 0.7 m in hole OSK-PHX-24-04
  • 6.76 g/t Au over 0.8 m and 9.63 g/t Au over 0.5 m in hole OSK-PHX-24-13
  • 9.52 g/t Au over 0.3 m in hole OSK-PHX-24-030

Marc-André Pelletier, President and CEO commented: “Today’s results are very encouraging and demonstrate geological similarities to the Windfall gold deposit. Notably, most of the drill hole intercepts at Moss are within 400 m below surface, with additional drilling planned to confirm mineralization continuity at depth. Osisko Mining intends to mobilize one additional drill rig in the next few months, bringing the total to six operational rigs at the Moss target. Although it’s still early in the discovery process, we’re excited by the results thus far and impressed by Osisko Mining’s commitment to accelerating the development of the Urban-Barry mining camp, where nearly ten million ounces have already been identified to date.”

Highlights of the Diamond Drilling Program:

The drilling program at the Moss target includes several drill fences designed at defining the lithostructural context of the area, which according to current geological models, is similar to that encountered at the Lynx Zone within the Windfall gold deposit. Notably, this involves exploring the presence of altered felsic volcanic rocks, felsic porphyritic dikes, and high-grade gold mineralization associated with quartz veins within the footwall of the Mazères fault. Additionally, these drill fences seek to intersect potential new mineralized lenses situated between the Mazères fault and the Moss showing.

Quality Control and Reporting Protocols (adopted by Osisko Mining)

NQ core assays were obtained by either 1-kilogram screen fire assay or standard 50-gram fireassaying-AA finish or gravimetric finish at ALS Laboratories in Val-d’Or, Québec, or Vancouver, British Colombia. The 1-kilogram screen assay method is selected by the geologist when samples contain coarse gold or present a higher percentage of pyrite than surrounding intervals. All samples are also analyzed for multi-elements, including silver, using Four Acid Digestion-ICP-MS method at ALS Laboratories. Drill program design, Quality Assurance/Quality Control (“QA/QC”) and interpretation of results is performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for QA/QC purposes by Osisko Mining as well as the lab.

Bonterra Intersects 1.77 g/t Au over 12.1 m, Including 2.33 g/t Au over 7.0 m on its 100% owned Desmaraisville South Project

Val-d’Or, QC – February 27, 2024 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce the results from its 15,000 meters (“m”) drill program at its 100% owned Desmaraisville South project. The purpose of the program was to test several new geological and geophysical targets along with historical near surface gold mineralization along the edges of the O’Brien Syenite Intrusion (“O’Brien Intrusive”) and to identify the location of a regional corridor of deformation located north of the property.

The diamond drilling was conducted within four kilometers (“km”) of the Bachelor Mill Complex. To date, Bonterra has received all assay results, including QA-QC samples, from the 57 diamond drill holes completed between August 23 and December 22, 2023. Please refer to press releases dated December 4, 2023, December 14, 2023, and February 5, 2024, for exploration updates on the Desmaraisville North and South projects and the surrounding area.

Highlights Include:

  • 1.77 g/t Au over 12.1 m, including 2.33 g/t Au over 7.0 m in hole BRDS-23-043
  • 0.61 g/t Au over 11.1 m in hole BRDS-23-033
  • 0.80 g/t Au over 5.6 m, including 5.27 g/t Au over 0.5 m in hole BRDS-23-002
  • 3.89 g/t Au over 1.0 m in hole BRDS-23-052

Marc-André Pelletier, President and CEO commented: “The drilling campaign at our 100%-owned Desmaraisville property resulted in the interception of several economic gold values and the discovery of new types of mineralization less than four km from the Bachelor Mill. Specifically, a gold intercept in hole BRDS-23-052 led to the discovery of a promising area along the OpawicaGuercheville regional deformation corridor, which hosts multiple gold showings over a 200 km long corridor in the region. Now that all of the results from the 2023 drilling campaign are in hand, our geology team is working on compiling and modeling these results, as well as the results of the 2023 geophysical surveys, to generate prospective drill targets for exploration later this year.

At our Phoenix JV, operated by Osisko Mining Inc., exploration efforts are progressing well, with approximately 6,000 m drilled to date. Currently, three drill rigs are focused on the Barry southwest target, while two are dedicated to the Moss target. As a reminder, the Moss target is located only five km southwest from the Windfall Gold deposit and shows a similar geological character to the Lynx Zone along the Mazères Fault that runs across both the Lynx Zone and the Moss target. Looking ahead, Osisko Mining plans to add a third drill rig at Moss in March, bringing the total operational rigs on the Phoenix JV to six.”

Highlights of the Diamond Drilling Results:

The diamond drilling program at the Desmaraisville South project had several objectives. The main objectives were to intersect gold mineralization; (1) on the eastern side of the O’Brien Intrusive (“East Area”), (2) along the extensions of various gold zones discovered in 2015 south of the O’Brien Intrusive (“South Area”) and finally, (3) to drill test geophysical targets and historical gold showings west of the Bachelor Lake felsic intrusion (“Bachelor Lake Intrusive”).

In addition, the ongoing geological and geophysical compilation work has allowed the company to identify two major gold-bearing structures: the Opawica-Guercheville deformation corridor, which hosts numerous gold showings and deposits that have been the subject of historical resource calculations, and the Lamarck-Wedding Fault, which hosts the former Lake Shortt Gold Mine (Figure 1).

The gold mineralized zone containing 1.77 g/t Au over 12.1 m, including 2.33 g/t Au over 7.0 m in hole BRDS-23-043 (Figure 2, Tables 1 and 2) consists of a strongly silicified and hematized zone with a brecciated texture. The zone contains up to 2% fine grained disseminated pyrite and is bordered at its lower contact by a fault zone.

The gold mineralized intersection in hole BRDS-23-033, which returned 0.61 g/t Au over 11.1 m, correspond to the up-dip projection of the intersection in hole BRDS-23-043. This gold mineralized zone comes to surface and is located 160 m to the west from the mineralized intersection in BRDS-23-043. The gold mineralization is hosted in the same basalt and brecciated and altered zone than hole BRDS-23-043 and is also bordered by a major fault at its lower contact (Figure 2, Tables 1 and 2).

BRDS-23-002 intersected a brecciated and highly silicified zone in a massive basalt. The zone is locally hematized and contains up to 2% fine grained disseminated pyrite and returned several gold intersections (Figure 2, Tables 1 and 2).

Finally, an exploration drill hole located North of the Bachelor Mill Complex, BRDS-23-052, tested the interpretated Opawica-Guercheville corridor of deformation and has returned a gold mineralized intersection containing 3.89 g/t Au over 1.0 m. The mineralized intersection consists of a strongly sericitized and sheared sedimentary unit with deformed quartz-carbonate veins and veinlets with traces of pyrite. Bonterra believes that the hole did not go across the entire corridor of deformation (Figure 3, Tables 1 and 2). Further drilling is warranted in this area to better evaluate the gold potential of the Opawica-Guercheville corridor of deformation.

Quality Control and Reporting Protocols

The Desmaraisville South project’s drill core gold analyses are performed at Activation Laboratories (“Actlabs”) located in Ste-Germaine-Boulé, Quebec, and at the Agat Laboratory (“Agat”) located in Val d’Or, 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 both Actlabs and Agat. 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 to 10% of the 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. For the entire drilling program, a total of 12,179 drill core samples and 2,160 QA-QC samples, have been sent to Actlabs and Agat.

Bonterra Intersects 2.23 g/t Au over 8.2 m, Including 9.26 g/t Au over 1.7 m on its 100% owned Desmaraisville South Project

Val-d’Or, QC – February 5, 2024 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce the latest results from its 15,000 meters (“m”) drill program at its 100% owned Desmaraisville South project. The purpose of the program was to test several new geological and geophysical targets along with historical near surface gold mineralization along the edges of the O’Brien Syenite Intrusion (“O’Brien Intrusive”) and to identify the location of two regional corridors of deformation located further to the North of the project.

The diamond drilling was conducted within seven kilometers (“km”) of the Bachelor Mill Complex. To date, Bonterra has received the assay results from 10,631 samples including QA-QC samples from the 57 diamond drill holes completed between August 23 and December 22, 2023. Assay results from 3,708 drill core samples are still pending. Please refer to press releases dated December 4 and December 14, 2023, for exploration updates on the Desmaraisville South project and the surrounding area.

Highlights Include:

  • 2.23 g/t Au over 8.2 m, including 9.26 g/t Au over 1.7 m in hole BRDS-23-021
  • 15.30 g/t Au over 1.0 m in hole BRDS-23-030
  • 0.80 g/t Au over 11.7 m, including 2.84 g/t Au over 1.4 m in hole BRDS-23-013
  • 3.66 g/t Au over 1.5 m in hole BRDS-23-004A

Marc-André Pelletier, President and CEO commented: “With the launch of the $10 million in exploration drilling as part of the Option Agreement with Osisko Mining on the Phoenix JV and positive results from the 2023 campaign at our 100%-owned Desmaraisville property, this year holds transformative potential for Bonterra. Notably, all drill hole mineralized intersections at Desmaraisville fall within 4 km of the Bachelor Mill Complex. The discovery of a new mineralization type on the east side of the O’Brien Intrusive in hole BRDS 23-021, distinct from the mineralization typically found at the Bachelor-Moroy deposits, underscores the possibility of new findings on the Desmaraisville property. Compilation work is ongoing, and the final interpretation of the 2023 geophysical surveys are expected soon. These findings will contribute to generating highly prospective drill targets for exploration later this year.”

Highlights of the Diamond Drilling Results:

The diamond drilling program at the Desmaraisville South project had several objectives. The main objectives were to intersect gold mineralization; (1) on the eastern side of the O’Brien Intrusive (“East Area”), (2) along the extensions of various gold zones discovered in 2015 south of the O’Brien Intrusive (“South Area”), (3) related to geophysical targets on the west of the Bachelor Lake felsic intrusion (“Bachelor Lake Intrusive”) enhanced by the presence of gold showings at surface and finally, (4) to test the deep southwest plunge of a zinc, lead, and silver mineralized body of the former Coniagas Mine (Figures 1 and 2).

In addition, drill holes were positioned to improve the understanding of the stratigraphy on the property and to better position the boundaries of the various formations within it. The Company is also seeking to better locate two major structures that affect these formations: the OpawicaGuercheville deformation corridor, which hosts numerous gold showings and deposits that have been the subject of historical resource calculations, and the Lamarck-Wedding Fault, host to the former Shortt Lake Gold Mine. Recent geophysical surveys on the Desmaraisville property should help Bonterra to properly position these two major structures.

The gold mineralized zone containing 2.23 g/t Au over 8.2 m, including 9.26 g/t Au over 1.7 m in hole BRDS-23-021 (Figures 2 and 3) is located at the contact between a tuff and a massive basalt rock unit. The contact zone is moderately silicified and contains 2-3% pyrite in clusters. This type of gold-bearing environment is different from the Bachelor and Moroy gold-bearing environment. This new mineralized zone appears to be related to a structural lineament trending N080 to N070 and this lineament is more than one km in length. Borehole BRDS-23-030 (Figure 2) is more than 275 m deep and has intersected an atypical gold mineralization characterized by a strong epidote alteration with a low sulphide content. The best mineralized interval returned a value of 15.30 g/t Au over 1.0m.

Drill hole BRDS-23-013 (Figure 4) intersected a gold enriched zone (0.80 g/t Au over 11.7 m, including 2.84 g/t Au over 1.4 m) associated with a strongly altered felsic dike west of the Bachelor Lake Intrusive. The host rocks directly in contact with the dike are strongly silicified. It remains to be determined whether the IP geophysical anomaly is related to this mineralized zone and if so, the mineralized zone could extend for several hundred metres.

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 both Actlabs and Agat. 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 to 10% of the 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. For the drilling program a total of 12,179 drill core samples and 2,160 QA-QC samples, have been sent to Actlabs and Agat.

Bonterra Announces Start of Exploration Drilling as part of the Option Agreement with Osisko Mining

Val-d’Or, QC – January 18, 2024 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce that exploration drilling has started on the newly named Phoenix JV (formerly known as the Urban-Barry Property) (the “Project”) as part of the definitive earn-in and joint venture agreement (the “Agreement”) with Osisko Mining Inc. (“Osisko” or the “Operator”). Under the Agreement, Osisko has the right to acquire up to a 70% interest in the Project by spending $30 million in work expenditures, with a minimum spending commitment of $10 million per year over a three-year period (see press release dated November 28, 2023).

Osisko plans to drill over 35,000 meters (“m”) on the Project in 2024, which Osisko expects will meet its minimum spending commitment of $10 million per year under the Agreement. The Operator has identified multiple targets on the Project, including the Moss target, which is located only five kilometres south-west from the Windfall Gold deposit and shows a similar geological character to the Lynx Zone. The Moss target will be tested along the Mazères Fault that runs across both the Lynx Zone and the Moss target.

Osisko plans to mobilize up to five drill rigs during the year, primarily along the Mazères Fault on the east and west sides of the Gladiator and Barry deposits and the Moss target (see Figure 1).

Marc-André Pelletier, Chief Executive Officer, and President of the Company commented “The start of exploration drilling by Osisko represents an important milestone in the development of the Project. With a $10 million exploration budget in 2024 and leveraging Osisko’s expertise in this exciting new gold camp, we believe we are well positioned for significant exploration success. In addition, the Company intends to continue exploring its 100%-owned Desmaraisville Property near the Bachelor Mill Complex in 2024. Compilation work from the 15,000 m drill program carried out in 2023 is ongoing and drilling results are expected to be released throughout Q1 2024. Last year’s exploration drilling combined with two geophysical surveys, also conducted in 2023, are expected to generate additional and promising drill targets to be tested later this year.”

Bonterra Completes an Airborne Gravity Survey and Initiates a Ground Geophysical IP Survey at its Desmaraisville Properties

Val-d’Or, QC – December 14, 2023 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce the completion of a highresolution helicopter-borne gravity survey and the commencement of a ground induced polarization (“IP”) survey at its Desmaraisville North and South Properties (the “Properties”). These comprehensive gravity and IP surveys are expected to assist the Company in its 2024 exploration program by generating exploration targets.

Bonterra contracted Sander Geophysics Ltd (“SGL”) based in Ottawa, Ontario to conduct a high-resolution helicopter-borne gravity survey on its Properties (Figure 1). The survey consisted of a total of 1,583 line-kilometers (“km”) at 200 meters (“m”) flight-line spacing and flown at a 60 m elevation over the entirety of the Properties. The purpose of the survey is to identify potential target areas of gold enrichment in enhanced basement alteration associated with large structural corridors and as well to identify potential targets for base metals (Zn, Pb and Ag) and strategic metals (Ni and Cu) associated with volcanic and ultramafic geological environments. The survey was completed in November and preliminary data has already been received. The final report and interpretations are expected by year end.

Bonterra has also contracted Abitibi Geophysics Inc. (“AG”) of Val-d’Or, Quebec to carry out an 85 line-km OreVision® 2D IP survey at its Desmaraisville South Property (Figure 2). The survey consists of a total of 80 line-km with a configuration of a = 37.5 m and n = 1 to 20 for a depth of investigation of 300 m. The surveyed area covers the Opawica-Guercheville corridor of deformation where numerous gold showings have been previously discovered and historical gold mineral resources have been estimated. The survey is expected to be completed by year end and will be used in combination with the gravity survey to identify and explore disseminated and massive sulfide mineralized zones in the Company’s as part of the Company’s 2024 exploration program.

In early December, Bonterra mobilized one drill rig south of the old Coniagas Mine to drill test the deep southwest plunge of a zinc, lead, and silver mineralized orebody (Table 1). InnovExplo of Val-d’Or, Quebec was contracted to compile and generate this exploration drill target. After the completion of the 900 m deep hole, Bonterra intends to contract AG to complete an InfiniTEM® XL BHEM survey with a patented loop configuration with depth potential up to 1,000 m. Historical production at Coniagas was over 700,000 tonnes at 10.8% Zn, 1% Pb and 183 g/t Ag.

Marc-André Pelletier, President and CEO commented: “Bonterra has redirected its exploration efforts to the 100%-owned Desmaraisville property located near the Bachelor Mill Complex after entering into an earn-in and joint venture agreement with Osisko Mining Inc. on the Urban-Barry property. The abovementioned geophysics surveys, combined with the 15,000 m drilling program currently underway, will be used to identify a fresh set of exploration targets for future drilling campaigns. We believe that the Desmaraisville property has very good potential for new discoveries in both gold and base metals, particularly around the O’Brien intrusive – host of the Bachelor-Moroy deposits and the newly discovered Desmaraisville South lens, and along the Opawica-Guercheville corridor. This regional deformation corridor, which crosses Bonterra’s property for more than 20 km, is conducive to discoveries and has had very little exploration activity in the past.”

Bonterra Intersects 10.97 g/t Au over 10.1 m, including 16.36 g/t Au over 4.7 m on its 100% owned Desmaraisville South Project

Val-d’Or, QC – December 4, 2023 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce the first drill results of its 15,000 meters (“m”) drill program at its Desmaraisville South project. Three diamond drill rigs have been mobilized on the project and are currently drill-testing several new geological and geophysical targets along with historical near surface gold mineralization along the edges of the O’Brien Syenite Intrusion (“O’Brien Intrusive”).

Located within three kilometers (“km”) of the Bachelor Mill Complex, three different areas were drill tested for their near surface gold potential. These areas are located North, East, and South of the O’Brien Intrusive (Figure 1).

At the Southern Area (“South Area”), several new drill targets were generated from the reinterpretation of previously intersected gold bearing structures. This reinterpretation was done with the use of the Bonterra drill hole database and the historical 3D models of high-grade gold intercepts drilled previously. Bonterra has drilled to date a total of 17 diamond drill holes (4,332 m) at the South Area (Figure 2 and Table 1).

Highlights include:

  • 10.97 g/t Au over 10.1 m, including 16.36 g/t Au over 4.7 m in hole BRDS-23-018
  • 4.79 g/t Au over 6.3 m, including 9.03 g/t Au over 1.5 m in hole BRDS-23-016
  • 2.65 g/t Au over 4.2 m in hole BRDS-23-016

Marc-André Pelletier, President and CEO commented: “After entering into an earn-in and joint venture agreement with Osisko Mining Inc. in the Urban-Barry camp, our Company has redirected its exploration efforts to focus on our 100%-owned Desmaraisville projects, which is close to where the Bachelor Mill Complex is situated. The current 15,000 m drill program aims to explore new targets across our land package and validate our improved geological interpretation. The recent discovery of mineralized zones at Desmaraisville South supports our current understanding of the gold potential, indicating similarities to the Bachelor and Moroy deposits on the western side of the O’Brien Intrusive, located about 3 km from the Bachelor Mill. The ongoing drill program with three rigs, set to conclude this year, should provide valuable insights that will guide our future exploration strategy. It is to be noted that the nearby Bachelor Mine historically produced over 350,000 ounces of gold from two million tonnes at a grade of 5.0 g/t Au.”

The drilling encountered several sub-parallel hematite and silica rich altered zones with trace to 8% fine grained and disseminated pyrite which host the gold mineralization (Table 2 and Figure 2). From hole to hole, these mineralized zones show various orientations and suggest that the gold mineralization is related to a large complex with brittle zones of various orientations and plunges. Many assays are still pending from the 3,955 submitted samples.

Bonterra’s review of the historical database demonstrated a lack of systematic sampling. Several gold mineralized intervals were not sampled above and below the mineralization. Bonterra will conduct a re-sampling program in early 2024. When all analytical data is received, Bonterra will update its 3D model including the geology, alteration, structures, and mineralization to better understand and evaluate the near surface gold potential of the South Area.

Quality Control and Reporting Protocols

The Desmaraisville project’s drill core gold analyses are performed at Activation Laboratories (Actlabs) located in Ste-Germaine-Boulé and Val d’Or, Quebec and at the Agat Laboratory in Val d’Or. The external laboratory 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 and with gravimetric finish for assay above 10 g/t Au at both Actlabs and Agat. 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 to 10% of the 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. For the South Area, a total of 3,955 drill core samples and 702 QA-QC samples, have been sent to Activation Laboratories Ltd and Agat Laboratory.
