 Val-d’Or, QC – February 6, 2025 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) congratulates Urbana Corporation (“Urbana”) on initiating a 4,150 meters (“m”) winter drill program on the Urbana property located adjacent to the Moss target on the Company’s Phoenix JV with Gold Fields Ltd. (see Urbana’s press release dated on February 3, 2025). 

The Urbana property is crossed by the regional Mazères Fault, which is the main structural corridor that hosts the Barry deposit (0.689 million ounces in the Measured and Indicated categories and 0.689 million ounces in the Inferred category) and where recent drilling at the Moss Target identified high-grade gold mineralization similar to the high-grade Lynx Zone at the Windfall project (see press releases dated December 11, 2024, August 6, 2024 and April 15, 2024). 

Cesar Gonzalez, Executive Chairman, commented: “We are pleased to see Urbana initiate a drilling campaign in this highly prospective and emerging gold camp, where nearly 10 million ounces of gold have already been discovered across the Windfall, Barry, and Gladiator deposits. Despite these significant discoveries, the camp remains underexplored, with strong potential for additional finds—demonstrated by the recent discovery of Lynx-type mineralization at the Moss Target by Gold Fields. We wish our neighbors at Urbana much success in their exploration campaign.”

Recent drilling results at the Moss target, where Lynx-style gold mineralization has been identified, highlights the strong potential for further discoveries. We are eager to collaborate with Gold Fields to advance Quebec’s newest emerging gold camp.” 

Additional Assay Results from the Moss Target 

To date, over 60,000 meters (“m”) have been drilled, and approximately C$16 million has been spent on the Project this year by Osisko under the JV Agreement. The extensive drilling program at Moss target has led to high-grade mineralization discovery similar to the Windfall-Lynx Zone. The extension at depth is confirmed by drill holes OSK-PHX-24-078 and OSK-PHX-24-096 returning 38.33 g/t Au over 1.1 m (including 69.6 g/t Au over 0.6 m) and 7.37 g/t Au over 4.2 m (including 28.6 g/t Au over 0.4 m), respectively (see press release dated August 6, 2024). The majority of the assay results have now been processed, with key results displayed on a longitudinal section in Figure 2. Significant intercepts not previously reported are shown below. 

Highlights at the Moss Target: 

• 6.23 g/t Au over 2.8m, including 18.1 Au g/t over 0.9m in hole OSK-PHX-24-112 
• 12.3 g/t Au over 0.5m and 3.97 g/t Au over 3.4 m in hole OSK-PHX-24-073 
• 7.50 g/t Au over 0.9 m, including 20.9 g/t Au over 0.3 m in hole OSK-PHX-24-106 
• 5.05 g/t Au over 1.0 m in hole OSK-PHX-24-053 

Start of Drilling by Gold Fields at the Phoenix JV 

Gold Fields is in the draft planning stage for a potential 20,000 meters drill program. Final targets remain subject to internal review and prioritization. Possible geophysical surveys are also at draft planning stage. The Operator has identified several prospective targets based on historical data including, gold showings, drill results, and geophysical surveys (see Figure 1 – Plan View of Target Areas on the Phoenix JV). 

Gold Fields plans to mobilize utilizing three to four drill rigs during the latest drilling campaign, primarily along the Barry Shear Zone where the Gladiator SW and NE/Titan targets are located. Those targets are next to the Gladiator deposit, which 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 mineral resource estimate (“2021 MRE”). In addition, a detailed review of the core samples from both Barry and Gladiator deposits is also planned. Other areas will be targeted such as Duke NE, Chanceux, Tourmaline Ridge extension and Rouleau Till as part of the program. Two drill rigs are currently turning on the Gladiator SW target, with over 3,000 m drilled to date.

Option Agreement Provides Osisko Mining an Option to Earn-In a 70% Interest in Bonterra’s Gladiator and Barry Projects, and Adjoining Duke and Lac Barry Properties 

Val-d’Or, QC – November 28, 2023 – Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR2) (“Bonterra” or the “Company”) is pleased to announce that it has executed a definitive earn-in and joint venture agreement (the “Agreement”) with Osisko Mining Inc. (“Osisko”), further to the news release of Bonterra dated September 25, 2023 and entitled “Bonterra Announces Binding Letter Agreement for Joint Venture with Osisko Mining”. Under the Agreement, Osisko has the right to acquire up to a 70% interest in the Company’s Gladiator and Barry projects, in addition to the adjoining Duke and Lac Barry properties held through joint venture agreements with Osisko and Gold Royalty Corp., respectively (collectively, the “Properties”), all located in Quebec’s Eeyou Istchee James Bay region and consisting of an aggregate of 496 claims over 22,508 hectares, as shown on the accompanying map. 

 Pursuant to the terms of the Agreement, Osisko has paid the Company initial up-front payments totalling $5 million. Osisko can earn a 70% interest in the Properties, reducing the Company’s interest in the Gladiator, Barry and Duke Properties to 30% and its interest in the Lac Barry joint venture to 15%, by expending $30 million dollars on qualifying expenditures on the Properties over the next three years. Specific terms of the Agreement include: 

• Completion of $30 million in work expenditures on the properties, with a minimum spending commitment of $10 million per year over the three year period following the execution of the Agreement; 

• Osisko will have the right to carry over work expenditures from year to year, and to pay cash in lieu of expenditures in the event of a shortfall; 

• Osisko will be the operator for the Properties during the exploration earn-in period; 

• Once a 70% interest in the Properties is earned by Osisko, the Properties will be operated as a joint venture (the “Joint Venture”), with Osisko as the operator, and each party required to contribute to future work expenditures in accordance with the proportional interests in the Joint Venture; 

• Dilution of a party to less than 10% of the Joint Venture will result in the conversion of their respective Joint Venture interest to a 1% net smelter return royalty, 50% of which is subject to a buyback right of $1 million; and 

• In its sole discretion, Osisko may accelerate its exercise of the earn-in right. 

Marc-André Pelletier, Chief Executive Officer and President of the Company, commented “We’re excited to announce our partnership with Osisko on the Properties. With a $30 million exploration budget over three years and leveraging Osisko’s expertise in this prolific gold camp, we believe we’re well positioned for significant exploration and development success on the Gladiator and Bary projects. Concurrently, we have three drill rigs turning at our 100%- owned Desmaraisville property near the Bachelor Mill Complex and are focusing on high-grade intercepts that were previously drilled, but not followed up on. 

With the additional $4 million received on closing ($1m already received) and the revenue streams from leasing the Bachelor camp and selling gold from the mill clean-up, we expect to have ample funds to complete this year’s more than 15,000 meters drill campaign at the Desmaraisville properties.” 

The Agreement has been approved by the TSX Venture Exchange. 

As payment for its role as the Company’s financial advisor in connection with the Joint Venture, Cormark Securities Inc. received an advisory fee of $200,000 in cash and $200,000 in common shares of the Company. McMillan LLP acted as the Company’s legal advisors in connection with the Joint Venture. Bennett Jones LLP acted as Osisko’s legal advisors in connection with the Joint Venture.

Val-d’Or, QC – March 27, 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 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 in the upper section of the deposit. In total, 31,349 meters (“m”) (91 holes) of infill drilling has been completed from surface since August 2022. The Company has received assays for 75 holes so far, including the ones in this release (see press releases dated November 15, 2022 and December 12, 2022 for previously released holes). 

 Highlights include: 

• 34.7 g/t Au over 2.4 m, including 72.0 g/t Au over 1.1 m in hole MB-22-560A 
• 17.7 g/t Au over 3.2 m, including 30.1 g/t Au over 1.8 m in hole MB-23-594 
• 11.6 g/t Au over 3.3 m, including 19.8 g/t Au over 1.8m in hole MB-23-589 
• 9.0 g/t Au over 9.2 m, including 21.7 g/t Au over 2.0 m in hole MB-22-578 
• 8.2 g/t Au over 6.0 m, including 17.6 g/t Au over 2.7 m in hole MB-22-556 
• 6.4 g/t Au over 4.0 m, including 13.2 g/t Au over 1.2 m in hole MB-22-565A 

 Duke Joint Venture Drill Program Update 

 In March, the Company announced a 3,300 m drill program at the Duke property (“Duke”), a joint venture with Osisko Mining Inc. (“Osisko”). 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.

Caution regarding 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 – April 7, 2022 – 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 the southwest sector at depth. The latest results obtained from 43 diamond drill holes are designed to increase the 2021 mineral resource estimate (“2021 MRE”) (see press release dated June 23, 2021). Drilling highlights include 7.1 grams-per-ton gold (“g/t Au”) over 7.6 metres (“m”) in the near-surface zone AB08, approximately 200 m northeast of the previously released intercept 8.0 g/t Au over 7.6 m (see press release dated October 5, 2021).

The Company is currently drilling at a rate of approximately 7,500 m per month, focused mainly on expanding its Barry and Gladiator gold deposits highlighted within the recently released 2021 MREs.

Highlights include:

• 7.1 g/t Au over 7.6 m, including 20.1 g/t Au over 1.4 m and 13.2 g/t Au over 1.4 m in hole MB-21-417
• 1.3 g/t Au over 12.0 m, including 3.0 g/t Au over 4.8 m in hole MB-21-404
• 2.3 g/t Au over 9.0 m, including 6.8 g/t Au over 2.6 m in hole MB-21-409
• 17.4 g/t Au over 4.4 m, including 146.0 g/t Au over 0.5 m in hole MB-21-410
• 10.8 g/t Au over 5.1 m, including 23.1 g/t Au over 1.4 m in hole MB-22-416
• 12.1 g/t Au over 6.1 m, including 73.5 g/t Au over 0.5 m in hole MB-22-420

Marc André Pelletier, President and CEO commented: “These recent drill results confirm the extension of the mineralization near surface and at depth at Barry, extending the existing mineral resource by over 200 m to the northeast from the resource pit shell, and up to 50 m to the southwest of the underground resource. The continuation of the H12 zone and the discovery of new H series at depth demonstrate the potential to add more ounces beyond the existing 2021 MRE.

Work is currently underway on a Preliminary Economic Assessment (“PEA”) based on the open pit resources at Barry in the 2021 MRE. The PEA is projected to be completed in late Q2 2022 and is expected to demonstrate the potential for restarting mining operations in the near term. The Company will soon undertake infill and definition drilling on the underground portion of the deposit to better understand the potential of an underground mining scenario.

At present, exploration activities at Barry include one drill rig drilling an additional 400 m to the northeast of the existing open pit resources and a second drill on regional exploration targets, approximately 5 kilometers to the northeast of the Barry deposit.

At the Bachelor Mine Complex, the permitting process for the mill and tailings management area expansion is ongoing, and the Company expects to provide additional information by mid-year with a COMEX permit expected by end of 2022 and provincial permits thereafter.”

The Barry drilling campaign is currently focused on the expansion of key gold mineralized northeast of the 2021 MRE. Multiple diamond drill holes have been designed to confirm the open pit extension potential to the northeast. Several drill holes have confirmed the extension of the mineralization near surface with large intercepts grading above the open pit resource cut-off grade (1.0 g/t Au). Specifically, hole MB-21-417 extended the near surface mineralization by 200 m with 7.1 g/t Au over 7.6 m, including 20.1 g/t Au over 1.4 m and 13.2 g/t Au over 1.4 m in the AB08 zone and 3.9 g/t Au over 6.3 m, including 10.1 g/t Au over 2.0 m in a new H series zone (figure 2).

Expansion drilling has also confirmed the mineral continuity and expansion of several known H-Type zones, particularly the H12 zone with holes MB-22-420 and MB-22-416, which respectively intersected 12.1 g/t Au over 6.1 m, including 73.5 g/t Au over 0.5 m and 10.8 g/t Au over 5.1 m, including 23.1 g/t Au over 1.4m, expanding the mineralization by 75 m at depth and 50 m to the southwest beyond the 2021 MRE (figure 3).

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.

The following table shows the significant intersections of the drill holes presented in this press release:

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 conducted 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.
