‘The LiDAR survey was highly successful in confirming the 1,600 metre known strike length of the Dos de Mayo vein system and, perhaps more importantly, has identified new structures, often with artisanal workings that may indicate the presence of vein material,’ stated Robert Archer, Pinnacle’s President & CEO.  ‘The sheer number of historic shafts, adits and pits interpreted from the LiDAR survey underscores the prospectivity of the project and, to date, we have focused only on the northernmost 10% of the property.  As such, we are adding to our geological team to follow up on these new targets.’

Figure 2:  El Potrero Block Showing Artisanal Workings Interpreted from LiDAR Defining Main Dos de Mayo Trend and New Target Areas

On the northern, or ‘El Potrero’, claim block (Figure 2), the majority of the 3 shafts, 50 adits and 29 pits clearly outline the known trace of the Dos de Mayo vein system and the more limited exposures of the El Capulin and La Estrella veins.  However, the LiDAR also indicates the potential for an extension to this system to the southeast, across the river valley, where it would be hosted in similar andesitic rocks.  In addition, there appears to be a previously unknown northeast-southwest trend on the southeast side of the valley, also in andesites, while similar northeast-southwest trends are observed in the southwest section, presumably hosted by intrusive rocks according to government regional geology maps.  This latter scenario could give rise to a different, intrusive-related, style of mineralization.  Regionally, northeast-trending structures pre-date the northwesterly trend and are host to the Ag-Pb-Zn-Au veins of the Topia Mine, 13 kilometres to the southwest.

On the separate Maria Fernanda 2 (‘MF2′) claim block to the southwest (Figure 3), 3 shafts, 14 adits and 22 pits are somewhat scattered across the concession.  While this area has never been explored by modern methods, government maps indicate a northwest-southeast trending structure passing through the middle of the block, parallel to the Dos de Mayo system and to the regional structural trend.  The LiDAR also indicates a number of smaller structures perpendicular to this trend.  The road from Topia passes through the middle of the block and road cuts locally display intense argillic alteration and pervasive chloritization with minor pyrite that, collectively, may be indicative of a buried hydrothermal system.  Several of the pits interpreted from the LiDAR appear to lie in close proximity to this zone. Pinnacle’s geological team is planning a systematic and thorough evaluation of the area, commencing early in the New Year.

The LiDAR survey covered the entire 11 km2 property and was flown by Eagle Mapping Ltd. of Langley, British Columbia.  Reprocessing and interpretation of the data was conducted by GeoCloud Analytics of Melbourne, Australia.

LiDAR, or Light Detection and Ranging, is a remote sensing technology that uses laser light to ‘see through’ vegetation and soil cover to measure distances, with 15-30 cm scale accuracy, to underlying rock surfaces.  In this way, it can map out features such as structures and lithological contacts that can be related to mineralization but may not be exposed at surface.  The survey also included colour aerial photography with 10-15 cm resolution that will assist in surface exploration and planning of infrastructure upgrades.

Qualified Person

Mr. Jorge Ortega, P. Geo, a Qualified Person as defined by National Instrument 43-101, and the author of the NI 43-101 Technical Report for the Potrero Project, has reviewed, verified and approved for disclosure the technical information contained in this news release.

About the Potrero Property

El Potrero is located in the prolific Sierra Madre Occidental of western Mexico and lies within 35 kilometres of four operating mines, including the 4,000 tonnes per day (tpd) Ciénega Mine (Fresnillo), the 1,000 tpd Tahuehueto Mine (Luca Mining) and the 250 tpd Topia Mine (Guanajuato Silver).

High-grade gold-silver mineralization occurs in a low sulphidation epithermal breccia vein system hosted within andesites of the Lower Volcanic Series and has three historic mines along a 500 metre strike length.  The property has been in private hands for almost 40 years and has never been systematically explored by modern methods, leaving significant exploration potential.

A previously operational 100 tpd plant on site can be refurbished / rebuilt and historic underground mine workings rehabilitated at relatively low cost in order to achieve near-term production once permits are in place. The property is road accessible with a power line within three kilometres.  

Pinnacle will earn an initial 50% interest immediately upon commencing production.  The goal would then be to generate sufficient cash flow with which to further develop the project and increase the Company’s ownership to 100% subject to a 2% NSR.  If successful, this approach would be less dilutive for shareholders than relying on the equity markets to finance the growth of the Company.

About Pinnacle Silver and Gold Corp.

Pinnacle is focused on the development of precious metals projects in the Americas.  The high-grade Potrero gold-silver project in Mexico’s Sierra Madre Belt hosts an underexplored low-sulphidation epithermal vein system and provides the potential for near-term production. In the prolific Red Lake District of northwestern Ontario, the Company owns a 100% interest in the past-producing, high-grade Argosy Gold Mine and the adjacent North Birch Project with an eight-kilometre-long target horizon.  With a seasoned, highly successful management team and quality projects, Pinnacle Silver and Gold is committed to building long-term, sustainable value for shareholders.

Rio Silver Inc. (TSX-V: RYO | OTC: RYOOF) (‘Rio Silver’ or the ‘Company’) is pleased to provide an update on its Maria Norte gold-silver-lead-zinc Project in central Peru, following the completion of recent technical work and site activities conducted in accordance with National Instrument 43-101. The results confirm the presence of high-grade silver mineralization, favorable geological and metallurgical characteristics, and a clear pathway toward near-term development within one of Peru’s most prolific silver districts.

Figure 1: Maria Norte Silver Project – NI 43-101 Verification Sampling Locations
Map outlining concession boundaries and surface verification sampling locations at Rio Silver’s Maria Norte high-grade silver project in central Peru.

High-Grade Silver Confirmed by Verification Sampling

As part of the independent National Instrument 43-101 review, verification sampling was conducted by James A. McCrea, P.Geo., the independent author of the NI 43-101 Technical Report, during a site visit to the Maria Norte Project in June 2025. Sampling targeted surface vein exposures and historic waste material and returned high-grade silver values, including:

• 869 g/t silver, with associated lead and zinc, from a 0.5-metre surface vein channel sample
• 991 g/t silver from a 0.7-metre surface vein channel sample
• 396 g/t silver from a historic waste dump grab sample

Table 1: Maria Norte Verification Sampling Results (NI 43-101)*

*Verification sampling returned silver values ranging from 396 g/t Ag to 991 g/t Ag, with associated lead, zinc, and localized gold values. These results confirm the presence of high-grade silver mineralization at surface, consistent with historical sampling by previous operators and characteristic of low-sulphidation epithermal vein systems common to the Huachocolpa District.

A total of four (4) verification samples were collected, consisting of three (3) chip samples from surface vein outcrops and one (1) grab sample from a historic waste dump, with chip sample widths ranging from approximately 0.4 metres to 0.7 metres. All samples were bagged, labelled, and sealed in the field using single-use security ties, transported by the author to Lima, Peru, and analyzed by Certimin S.A., an ISO 9001–certified laboratory located in the Santiago de Surco municipality of Lima.

No additional quality control samples (blanks, standards, or duplicates) were inserted due to the limited number of samples collected, which the author considered appropriate for the exploration stage of the project. James A. McCrea, P.Geo. concluded that the sampling methods, sample handling, preparation, and analytical procedures are adequate for data verification purposes, and that the results are representative of the surface mineralization observed at Maria Norte.

CEO Comment

‘The confirmation of high-grade silver at Maria Norte reinforces what initially attracted us to this project,’ said Chris Verrico, President and Chief Executive Officer of Rio Silver. ‘These are good grades in a district known for long-life silver production, and as our team continues work on the ground, we are seeing encouraging geological indications that suggest the system may extend beyond what is currently exposed. Combined with existing infrastructure, favorable metallurgy, and strong community engagement, we believe Maria Norte offers a compelling opportunity to advance toward development while continuing to unlock further upside.’

Proven Geological Setting in a Renowned Silver District

Maria Norte is situated within the Miocene polymetallic belt of central Peru, a region that has supported decades of silver production from structurally controlled epithermal vein systems. Mineralization at Maria Norte occurs within quartz-sulphide veins and breccias, hosting silver-dominant mineralization with associated lead, zinc, and local gold values.

Mapping and structural interpretation indicate that mineralization is controlled by a well-defined vein corridor with favorable geometry for continuity along strike and at depth. This geological setting mirrors other productive operations in the district and supports the Company’s development-focused exploration strategy.

Infrastructure, Metallurgy, and Development Readiness

Historic metallurgical test work reviewed by the Company indicates that mineralization at Maria Norte responds to conventional flotation methods. Combined with the project’s location within a well-established mining district, this supports a development approach that emphasizes efficiency and capital discipline.

Key advantages at Maria Norte include:

• Favorable Metallurgy: Historic test work indicates amenability to conventional flotation processes.
• Established Infrastructure: Road access and operating processing facilities are located approximately 11 kilometers from the project.
• Reduced Capital Intensity: Proximity to existing mills has the potential to lower upfront capital requirements, shorten development timelines and reduce exposure to environmental costs related to mill operation.
• Experienced Mining District: Maria Norte is located within one of Peru’s longest-producing silver regions, which has a well-established, supportive mining culture, and experienced local workforce.

Following the recent approval of the Maria Norte acquisition, Rio Silver has advanced boots-on-the-ground activities, including site access planning, infrastructure assessments, and early permitting preparations. In parallel, the Company continues constructive engagement with local community leaders, building on a foundation of cooperation in one of Peru’s most established and supportive mining regions.

Positioned for Near-Term Development

Rio Silver’s strategy at Maria Norte is focused on advancing accessible, high-grade mineralization through staged development while continuing exploration to expand the known system. Under Peru’s established exploration and exploitation framework, development activities can progress alongside exploration, allowing the Company to advance the project efficiently and responsibly.

Management believes that the combination of verified high-grade silver, nearby processing capacity, and an experienced in-country team places near-term development firmly within the Company’s strategic horizon, subject to continued technical success and permitting.

Next Steps

• Advance Development Planning at Maria Norte: Continue site preparation activities, infrastructure assessments, and permitting work in support of staged underground access targeting accessible high-grade silver mineralization.
• Expand Geological Understanding of the System: Complete detailed mapping, channel sampling, and geophysical surveys to refine priority targets and assess continuity along strike and at depth within the known vein corridor.
• Progress Community and Stakeholder Engagement: Maintain active dialogue with local communities and stakeholders to finalize access agreements and support responsible development as work programs advance.
• Parallel Metallurgical Work at Santa Rita: Advance ongoing metallurgical test work to better understand mineral processing characteristics while technical evaluations and project integration continue.

Why This Matters to Investors

As global silver markets continue to experience structural supply deficits, projects capable of advancing high-grade silver toward development are scarce. Maria Norte stands out due to its verified grades, district-scale setting, proximity to operating mills, and disciplined development strategy. With key technical milestones achieved and field activities advancing, Rio Silver believes it is well positioned to deliver continued progress and value creation for all stakeholders as the silver cycle unfolds.

Data Verification and Qualified Persons

The author’s verification samples were sent to Certimin S.A. laboratories in the Santiago de Surco Municipality of Lima. Samples were collected in the field under the supervision of the author, as chip samples from vein outcrops and a grab sample from a waste dump; the samples were bagged, labelled and sealed with one-use ties at the time they were taken. The samples were transported by the author, from the Project to Lima and then to Certimin S.A. in Lima for final preparation.

Nevgold Corp. (‘NevGold’ or the ‘Company’) (TSXV:NAU,OTC:NAUFF) (OTCQX:NAUFF) (Frankfurt:5E50) is pleased to announce positive, consistent antimony (‘Sb’) and gold (‘Au’) pit sampling results from the historical gold leach pads at its Limousine Butte Project (the ‘Project’, ‘Limo Butte’) in Nevada. The historical gold leach pads were from mining operations in 1989-1990, which had no focus on antimony in a significantly lower gold price environment at less than US$400oz of gold. The historical leach pads are an opportunity for potential near-term antimony production. Based on historical records, it is estimated that between 2.4 million to 3.0 million tonnes of previously mined material exists on the leach pads at surface with positive, consistent antimony and gold grades based on NevGold sampling.

Key Highlights

• Large quantities of previously mined material with significant antimony at surface in historical Crushed and Run of Mine (‘ROM’) gold leach pads are an opportunity for near-term antimony production:

• • 2025 metallurgical testwork showed acid leaching with antimony recoveries up to 92%
  • Antimony recovery has minimal to no impact on gold recovery; the gold in the historical leach pads could also be recovered in the future after antimony processing is completed
  • Acid Leaching is being reviewed as the preferred metallurgical process for antimony as there is currently no reliance on downstream processing at third-party smelters or refineries; the acid leaching scenario would produce antimony metal at site through a conventional leaching scenario, which has many similarities to Solvent Extraction-Electrowinning (SX/EW) used for oxide copper in the copper industry

• Antimony is one of the highest priority Critical Minerals due to its strategic importance and military applications; Limo Butte is a brownfield mine site located in the State of Nevada with near-surface, high-grade antimony mineralization

• • Historical leach pads provide opportunity for near-term antimony production
  • The larger commercial gold-antimony opportunity can be advanced and developed in parallel to the historical leach pad opportunity, including drilling, metallurgical testwork, and the preparation of a Mineral Resource Estimate (‘MRE’) at Resurrection Ridge (including high-grade antimony Bullet Zone discovery made in 2025) and Cadillac Valley
  • A staged project development approach offers various potential development scenarios over the next 12-24 months which may achieve near-term production and cash flow

Limo Butte Planned 2025-2026 Activities / Status Update
NevGold will continue its active exploration program at Limo Butte including:

• Evaluating the historical geological database with focus on gold and antimony (completed);

• Advancing metallurgical testwork (Phase II completed);

• Continuing to drill test gold-antimony targets (ongoing, 30 drillholes completed to date);

• Advancing the Crushed and Run of Mine (‘ROM’) leach pads to near-term antimony production (Phase I sampling completed, Company will immediately commence sonic drilling and metallurgical testwork);

• Completing initial gold-antimony Mineral Resource Estimate (MRE) (in progress).

NevGold CEO, Brandon Bonifacio, comments: ‘We are extremely excited about the significant positive development around the Phase I pit sampling program of the historically mined gold leach pads at Limo Butte, as these results de-risk and rapidly advance the potential for near-term antimony production at the Project. As Limo Butte is a brownfield mine site, one key advantage is having a large amount of historically mined material already on surface in the leach pads that had a previous focus only on gold mineralization. There are a number of development scenarios that become viable with the addition of leach pad material, and all scenarios are being evaluated. We have the opportunity to be one of the near-term solutions to the United States building a fully vertically integrated antimony supply chain.’

Bonifacio continues: ‘In parallel with advancing the historical leach pad opportunity, we are also progressing the larger commercial gold-antimony mining operation at the Project with drilling, metallurgical test work, and a planned gold-antimony MRE at Resurrection Ridge (including the high-grade antimony-gold Bullet discovery made in 2025) and Cadillac Valley. This offers the Company significant optionality as we look to advance Limo Butte to a production and cash-flow scenario.’

US Executive Order – Announced March 20, 2025
The Company is pleased to report the sweeping Executive Order to strengthen American mineral production and reduce U.S. reliance on foreign nations for its mineral supply. Antimony (Sb) has been identified as an important ‘Critical Mineral’ in the United States essential for national security, clean energy, and technology applications, yet limited domestic mine supply currently exists.

The Executive Order invokes the use of the Defense Production Act as part of a broad United States (‘US’) Government effort to expand domestic minerals production on national security grounds. As it relates to project permitting, the Order states that it will ‘identify priority projects that can be immediately approved or for which permits can be immediately issued, and take all necessary or appropriate actions…to expedite and issue the relevant permits or approvals.’ Furthermore, the Order includes provisions to accelerate access to private and public capital for domestic projects, including the creation of a ‘dedicated mineral and mineral production fund for domestic investments’ under the Development Finance Corporation (‘DFC’).

This decisive action by the US Government highlights the urgent need to expand domestic minerals output to support supply chain security in the United States. This important Order will help revitalize domestic mineral production by improving the permitting process and providing financial support to qualifying domestic projects.

Importance of Antimony
Antimony is considered a ‘Critical Mineral’ by the United States based on the U.S. Geological Survey’s 2022 list (U.S.G.S. (2022)). ‘Critical Minerals’ are metals and non-metals essential to the economy and national security. Antimony is utilized in all manners of military applications, including the manufacturing of armor piercing bullets, night vision goggles, infrared sensors, precision optics, laser sighting, explosive formulations, hardened lead for bullets and shrapnel, ammunition primers, tracer ammunition, nuclear weapons and production, tritium production, flares, military clothing, and communication equipment. Other uses include technology (semi-conductors, circuit boards, electric switches, fluorescent lighting, high quality clear glass and lithium-ion batteries) and clean-energy storage.

Globally, approximately 90% of the world’s current antimony supply is produced by China, Russia, and Tajikistan. Beginning on September 15, 2024, China, which is responsible for nearly half of all global mined antimony output and dominates global refinement and processing, announced that it will restrict antimony exports. In December-2024, China explicitly restricted antimony exports to the United States citing its dual military and civilian uses, which further exacerbated global supply chain concerns. (Lv, A. and Munroe, T. (2024)) The U.S. Department of Defense (‘DOD’) has designated antimony as a ‘Critical Mineral’ due to its importance in national security, and governments are now prioritizing domestic production to mitigate supply chain disruptions. Projects exploring antimony sources in North America play a key role in addressing these challenges.

Perpetua Resources Corp. (‘Perpetua’) has the most advanced domestic gold-antimony project in the United States. Perpetua’s project, known as Stibnite, is located in Idaho approximately 130 km northeast of NevGold’s Nutmeg Mountain and Zeus projects. Positive advancements at Stibnite including technical development and permitting has led to US$75 million in Department of Defense (‘DOD’) awards, over $1.8 billion in indicative financing from the Export Import Bank of the United States (‘US EXIM’) (see Perpetua Resources News Release from April 8, 2024) (Perpetua Resources. (2025)), and recent strategic investments of US$180 million from Agnico-Eagle Mines Limited (‘Agnico’) and US$75 million from JPMorganChase’s $1.5 trillion Security and Resiliency Initiative.

The six holes are the latest completed as part of the Company’s ongoing 140,000-metre step-out drill program designed to test the overall scope of gold mineralization at the Project (see Radisson news release dated October 16, 2025). Two of the holes represent the twelfth and thirteenth directional wedges completed from pilot hole OB-24-337 and serve to expand the broad area of new high-grade mineralization being delineated across multiple veins beneath the historic O’Brien Gold Mine. All six of the holes released today intersected gold mineralization, and five of the holes returned intercepts with grades and thicknesses consistent with the Project’s existing mineral resources, continuing the very high success rate of the current drill program. Highlights include:

• OB-25-337W13 intersected 90.60 grams per tonne (‘g/t’) gold (‘Au’) over 1.0 metre within a mineralized interval averaging 30.59 g/t Au over 3.0 metres and 9.14 g/t Au over 2.7 metres, including 16.35 g/t Au over 1.4 metres;

• OB-25-337W12 intersected 25.10 g/t Au over 1.5 metres and 14.20 g/t Au over 1.5 metres and 11.40 g/t Au over 1.3 metres;

• OB-25-322W2 intersected 3.11 g/t Au over 8.0 metres including 5.93 g/t Au over 1.5 metres and 3.62 g/t Au over 4.0 metres including 6.33 g/t Au over 1.5 metres;

• OB-25-322W1 intersected 4.02 g/t Au over 4.5 metres, including 8.29 g/t Au over 1.5 metres;

Matt Manson, President and CEO: ‘Today we are releasing six new drill holes from our ongoing deep step-out drill program at O’Brien. These continue to illustrate the extension of the Project’s system of gold mineralization below the historic O’Brien mine and the current mineral resources. Of particular note are the two new wedges completed from pilot hole OB-24-337 located beneath the former mine’s final stope. These are the twelfth and thirteenth such wedges completed. Once again, we are seeing multiple high-grade intercepts of quartz-sulphide veins within broader alteration envelopes. This represents a system of gold mineralization that we have modelled as up to six veins delineated over a 250-metre (east-west) by 500-metre (vertical) area that remains open. With this step-out drill program we are steadily pushing the limits of known mineralization at O’Brien outwards and downwards. Overall, we have now completed 74 drill holes in the 140,000 metres program, 61 of which have intersected mineralization with grades and thicknesses consistent with the Project’s current mineral resources, an 82% success rate. As we start 2026, we will be operating seven drill rigs at site and ramping up to our eighth rig presently. Twelve additional step-out drill holes, including the final OB-24-337 wedges, have been completed and are awaiting assays.’

Table 1: Assay Results from Select Drill Holes

Notes on Calculation of Drill Intercepts:
The O’Brien Gold Project Mineral Resource Estimate effective May 6, 2025 (‘MRE’) utilizes a 2.20 g/t Au bottom cut-off, a US$2,000 gold price, a minimum mining width of 1.2 metres, and a 40 g/t Au upper cap on composites. Intercepts presented in Table 1 are calculated with a 3.00 g/t Au bottom cut-off. True widths, based on depth of intercept and drill hole inclination, are estimated to be 30-80% of core length. Table 2 presents additional drill intercepts calculated with a 1.00 g/t bottom cut-off over a minimum 1.0 metre core length so as to illustrate the frequency and continuity of mineralized intervals within which high-grade gold veins at O’Brien are developed. Lithology Codes: PON-S3: Pontiac Sediments; V3-S, V3-N, V3-CEN: Basalt-South, North, Central; S1P, S3P: Conglomerate; POR-S, POR-N: Porphyry South, North; TX: Crystal Tuff; ZFLLC: Larder Lake-Cadillac Fault Zone.

Gold Mineralization at O’Brien

Gold mineralizing quartz-sulphide veins at O’Brien occur within a thin band of interlayered mafic volcanic rocks, conglomerates, and porphyritic andesitic sills of the Piché Group occurring in contact with the east-west oriented Larder Lake-Cadillac Break (‘LLCB’). Gold, along with pyrite and arsenopyrite, is typically associated with shearing and a pervasive biotite alteration, and developed within multiple Piché Group lithologies and, occasionally, the hanging-wall Pontiac and footwall Cadillac meta-sedimentary rocks.

As mapped at the historic O’Brien mine, and now replicated in the modern drilling, individual veins are generally narrow, ranging from several centimetres up to several metres in thickness. Multiple veins occur sub-parallel to each other, as well as sub-parallel to the Piché lithologies and the LLCB. Individual veins have well-established lateral continuity, with near-vertical, high-grade shoots developed over significant lengths. Based on the historic data available, it is clear that the former mine was ‘high-graded’, with mining focussed on a main central stope and parallel veins identified but left undeveloped.

The historic O’Brien mine produced over half a million ounces of gold from such veins and shoots at an average grade exceeding 15 g/t Au and over a vertical extent of at least 1,000 metres. Modern exploration has focussed on delineating well developed vein mineralization to the east of the historic mine, with additional high-grade shoots becoming evident in the exploration data over what has been described as a series of repeating trends (‘Trend #s 0 to 5’).

Step-Out Drilling at O’Brien

Since the end of 2024, Radisson has been pursuing a program of broad step-outs beneath the historic O’Brien Gold mine and the existing mineral resources designed to test the extent of mineralization at the Project. This drilling is accomplished with pilot holes followed by wedges and directional drilling to maximize drill efficiency. On October 16, 2025, Radisson announced the expansion of the step-out drill program to 140,000 metres employing an eventual eight drill rigs.

The origin of the step-out drill program was the deep pilot hole OB-24-337, which was the first exploration drill hole located below the former mine workings since mining ended in 1957. This hole intersected 31.24 g/t Au over 8.0 metres, including 242.0 g/t Au over 1.0 metre at approximately 1,500 metres vertical depth (see Radisson news release dated December 16, 2024). With today’s results, assay results from a total of thirteen wedges from OB-24-337 have now been reported and up to six gold-bearing veins have been delineated over an area of approximately 250 metres (east-west) by 500 metres (vertical). The thirteenth wedge, released today, intersected 9.14 g/t Au over 2.7 metres including 16.35 g/t Au over 1.4 metres within Piché rocks just 40 metres below the final historic mining stope (Figures 1 and 3). The final two wedges, the fourteenth and fifteenth, have been completed and assay results are expected shortly. Future drilling in this area will utilize new pilot holes and wedge extensions to test the full scope of mineralization down to 2 kilometres depth.

Notes:
Hole lengths for wedges represent meterage from point of wedge. Drill hole OB-24-337 was completed in 2024 while its wedge branches were drilled in 2025.

Today’s results also include the first and second wedges completed from pilot drill hole OB-24-322, which intersected high-grade mineralization on the downwards extension of Trend #1 at 1,280 metres and 1,360 metres vertical depth, respectively. These two wedges appear to have intersected the same mineralized zone over a vertical separation of 80 metres, returning similar intercepts of 4.02 g/t Au over 4.5 metres, including 8.29 g/t Au over 1.5 metres (OB-25-322W1) and 3.11 g/t Au over 8.0 metres including 5.93 g/t Au over 1.5 metres and 3.62 g/t Au over 4.0 metres including 6.33 g/t Au over 1.5 metres (OB-25-322W2). Additional drill wedges from OB-24-322 have been completed and assays are pending.

Drill hole OB-25-371W7 is the seventh wedge from a pilot hole centered on the deep extension of Trend #2. It returned three separate intercepts of gold mineralization that were short, but with grades and thicknesses consistent with the Project’s mineral resources, in an untested area on the western side of Trend #2 towards the deep extension of Trend #1 (Figure 1). The Company considers the apparent ‘gap’ between the deep extensions of these two mineralizing trends to be a function of drill coverage rather than mineralization (Figure 2). This area offers a significant opportunity to delineate future mineral resources at relatively shallow depths and within the scope of the mine design contained in the Project’s 2025 Preliminary Economic Assessment. Further drill testing here will be an important part of the upcoming 2026 work program. The sixth drill hole release today, OB-25-377, was located in a gap area between the western and eastern portions of the former mine and intersected three narrow zones of minor mineralization.

QA/QC

All drill cores in this campaign are NQ in size. Assays were completed on sawn half-cores, with the second half kept for future reference. The samples were analyzed using standard fire assay procedures with Atomic Absorption (AA) finish at ALS Laboratory Ltd, in Val-d’Or, Quebec. Samples yielding a grade higher than 10 g/t Au were analyzed a second time by fire assay with gravimetric finish at the same laboratory. Mineralized zones containing visible gold were analyzed with metallic sieve procedure. Standard reference materials, blank samples and duplicates were inserted prior to shipment for quality assurance and quality control (QA/QC) program.
