Company Data

Introduction

Pinnacle Silver and Gold is focused on district-scale exploration for precious metals 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.

Projects in Hand

El Potrero Gold-Silver Project, Mexico

• Past producing (1989 - 1990) gold-silver mine in the heart of Mexico’s Sierra Madre Belt, one of the most prolific gold-silver producing regions in the world
• High-profile address – 4 operating mines within a 35 km radius
• Cienega (Fresnillo) – 4,000 tpd Au-Ag-Pb-Zn
• Tahuehueto (Luca Mining) – 1,000 tpd Au-Ag-Cu-Pb-Zn
• Topia (Guanajuato Silver) – 250 tpd Ag-Au-Pb-Zn
• San Geronimo (private) – 150 tpd Ag-Pb-Zn
• 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. A historic resource based upon underground sampling of those three mines is reported to consist of 45,561 tonnes at 8.0 g/t gold and 186 g/t silver. 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 operating 100-tonne-per-day 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. Surface rights covering the plant and mine area are privately owned (no community issues).
• Good Infrastructure
• Drive (8 hours) or fly (1 hour) from Durango City into Topia
• Mining town with skilled labour, supplies, etc.
• Road accessible, power line within 3 km
• Sits on a ‘ledge’, making logistics easier
• Water in river valley below
• Pinnacle will earn an initial 50-per-cent 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 per cent (subject to a 2-per-cent net smelter return royalty). If successful, this approach would be less dilutive for shareholders than relying on the equity markets to finance the growth of the Company.

Exploration & Development

• Vein system has been mapped & sampled for 1.6 km along regional NW-SE trend
• Vein in old pit returned 13.2 g/t Au and 2,280 g/t Ag and 5.2 g/t Au and 745 g/t Ag from 2 grab samples. Visible gold and the more typical ‘ginguro’ mineralization were observed.
• Multiple artisanal mines along complex vein system in anastomosing pattern
• All historic mines have been cleaned; Pinos Cuates and Dos de Mayo mines have been mapped and sampled, with follow-up sampling continuing
• Lack of any systematic ‘modern’ exploration increases potential for development of district-scale operation

Progress to Date

In four months Pinnacle has made significant progress:

• Cleaned all roads, trails and plant area; Rehabilitation of historical underground workings
• Underground mapping and sampling of 343 metres in Pinos Cuates and Dos de Mayo mines; 515 samples taken
• Delineated 35-metre-long zone of mineralization averaging 12.2 g/t Au equivalent with average width of 2.5 metres
• Traced Dos de Mayo vein system for 1,600 metres along strike, mapping with detailed follow up, cleaning of old trenches and sampling; 228 samples taken
• Discovered surface showing with 2,280 g/t Ag and 13.2 g/t Au
• Enhanced geological understanding of controls on mineralization
• Assessed plant infrastructure; Estimate of cost & time requirements for restart in progress
• Developing permitting strategy; Initiated baseline studies; Arranged meeting with environmental authorities for review of permit requirements
• Developing good relationships with local communities, providing jobs

Next Steps

• Continued surface mapping and sampling
• Follow-up underground sampling of Pinos Cuates and Dos de Mayo mines then mapping & sampling of La Dura mine
• Redesign of plant & complete cost & time requirements for restart
• Meet with environmental authorities for review of permit requirements – Baseline studies
• Property-wide LiDAR survey
• Underground and surface diamond drilling later in 2025
• Seeking a permit exemption for underground drilling
• Initiate discussions with federal electrical authority regarding extension of power line to plant site
• Discuss potential offtake agreement & project financing with metal traders

North Birch & Argosy Gold Mine Projects, Ontario

• Projects are almost contiguous & comprise a total of 4,454 hectares

Argosy Gold Mine Project

• Past producing (1931 - 1952) gold mine adjacent to North Birch Project
• 101,875 oz of gold produced at 12.7 g/t
• Pinnacle owns 100% subject to a 2.5% NSR
• Only 72 historic drill holes (>10,500 m) and no work on property since 2004
• Depth Potential
• Only 4 veins mined, to a maximum depth of about 270 metres
• 2002-04 drilling intersected multiple new, unmined veins and gold mineralization extending to a vertical depth of 400 m
• 3D Leapfrog model illustrates depth potential below old mine workings

North Birch Gold Project

Iron Formation Target

• Folded Iron Formation (IF) is an attractive target for gold mineralization
• IF hosted Au deposits are well known throughout the world
• Largest is Homestake Mine, S. Dakota: 40+ Moz
• Similar structural setting to Musselwhite Mine (Newmont-Goldcorp; 7+ Moz in past production & Reserves), also in NW Ontario

Summary

News Update

On February 26, 2026, Pinnacle Silver and Gold Corp. has provided an update on various aspects of the high-grade El Potrero project in Durango, Mexico, as it continues to advance toward a production decision. Since commencing work on the project one year ago, Pinnacle has made significant progress in following parallel tracks to fast-track the project toward a production decision as the goal is to commence production as soon as possible.

Having completed extensive underground and surface channel sampling and 3-D modelling, the company is in a position to commence rehabilitation of the historic mine workings on the main Dos de Mayo vein trend. Underground delineation drilling will commence following the preparation of drill stations. In addition, an application for the surface drilling permit has been submitted, a second round of metallurgical testing is under way, a feasibility study for the extension of the power line has been commissioned and a new access agreement has been signed with the local community.

"One year in, we are extremely pleased with the progress to date on the Potrero project," stated Robert Archer, president and chief executive officer of Pinnacle. "The commencement of underground rehabilitation is a significant milestone in the advancement of the project as it is not often that the first drill program on a project comprises underground delineation drilling rather than surface exploration. We believe that the underground drilling program will be followed immediately by surface drilling. Following on the excellent results of our first round of metallurgical tests that returned an average of 95.1-per-cent gold recovery, this current round of tests will add mineralogical studies, more extensive gravity separation and optimization of leach tests. The feasibility study for the power line extension will provide the details we need to get approval from the Comision Federal de Electricidad and give us an estimate of costs and time required for this activity. Importantly, we have signed an agreement with the local Ejido El Carmen supporting our work on their land covering the northern block of the Potrero project, where the mines and plant are located. With all of this work moving forward in parallel to derisk the project, we anticipate being able to make a production decision before year-end."

On February 23, 2026, Pinnacle Silver and Gold Corp. has signed an amendment agreement with the vendor of the Potrero project in Durango, Mexico, whereby the original payment of $750,000 (U.S.) due on Feb. 21, 2026 (see Pinnacle news release of Feb. 24, 2025), will be split into three equal portions. The new payment schedule will comprise payments of $250,000 (U.S.) on each of Feb. 24, May 24 and Aug. 24, 2026. All other cash payments and share issuances remain the same.

Robert Archer, president and chief executive officer of Pinnacle, stated: "We are very appreciative of the opportunity to spread out the payments as this will allow us to better budget our direct project costs and place more emphasis on advancing the project. With our recently completed financing, we are continuing our fast-track approach to production at El Potrero with the upcoming underground drilling program."

On February 04, 2026, Pinnacle Silver and Gold Corp. has signed a one-year contract, effective Feb. 1, 2026, with San Diego Torrey Hills Capital, to provide investor relations services for the company. Under the terms of the agreement, Pinnacle will pay SDTHC $2,000 (U.S.) per month and issue a one-time grant of 300,000 three-year incentive stock options in the share capital of the company. The options granted pursuant to the agreement shall vest as follows: (i) 25 per cent on the three-month anniversary of the date of grant; (ii) 25 per cent on the six-month anniversary of the date of grant; (iii) 25 per cent on the nine-month anniversary of the date of grant; and (iv) 25 per cent on the 12-month anniversary of the date of grant. The options are subject to the approval of the TSX Venture Exchange.

The company is also granting, subject to TSX-V approval, 2.17 million incentive stock options to directors, officers and consultants of the company. These options will be valid for three years and will vest immediately. All options granted herein shall have an exercise price of 20 cents.

On February 02, 2026, Pinnacle Silver and Gold Corp. has closed a second and final tranche of the non-brokered private placement announced on Nov. 25, 2025. Pursuant to the closing of the second and final tranche of the offering, the company issued 10,915,492 units at a price of 14 cents per unit for gross proceeds of $1,528,169. With the completion of this tranche, the offering is now fully subscribed for total gross proceeds of $2,595,713 and consisted of a total of 18,540,663 units, with each unit comprising one common share in the capital of the company and one-half share purchase warrant. Each whole warrant shall be convertible into an additional share at an exercise price of 20 cents for a period of 24 months from the date of issuance.

The net proceeds raised from the offering will be used to advance the high-grade El Potrero gold-silver project in Durango, Mexico, for project evaluations and for general working capital.

On January 20, 2026, Surface and underground sampling of the Estrella vein at Pinnacle Silver and Gold Corp.'s high-grade El Potrero gold-silver project in Durango, Mexico, has confirmed the presence of strong gold-silver mineralization in that vein. The limited mine workings are 42.5 metres long and channel sampling identified two mineralized zones yielding 5.49 grams per tonne Au (gold) and 48 g/t Ag (silver) over an average width of 0.72 metre and strike length of 12 metres, and 1.87 g/t Au and 51 g/t Ag over an average width of 1.1 metres and a strike length of 22.5 metres. The two zones are separated by 18 metres of lower-grade material in the adit but could coalesce below this. Individual samples assayed up to 17.7 g/t Au and 24 g/t Ag over 0.5 metre, 8.77 g/t Au and 32 g/t Ag over 0.5 metre, and 3.51 g/t Au and 196 g/t Ag over 0.8 metre. On surface, the vein has been traced for almost 150 metres along strike and is still open in both directions, reaching a width of 6.0 metres at the northern end of the exposure. Systematic channel sampling will be conducted in the coming weeks as, to date, grades from surface sampling reached 3.35 g/t Au and 204 g/t Ag.

Following up on the underground channel sampling at the historic La Dura 2 mine workings that returned 1.98 g/t Au and 98 g/t Ag along a 12-metre strike length (see Pinnacle news release of Nov. 12, 2025), surface sampling of the vein has extended the gold-silver mineralization along strike such that the zone can now be followed for approximately 45 metres. Within the seven vein samples taken on surface, assays included 6.89 g/t Au and 208 g/t Ag over 1.4 metres, 5.95 g/t Au and 185 g/t Ag over 1.0 metres, 5.75 g/t Au and 230 g/t Ag over 0.7 metres, and 3.39 g/t Au and 248 g/t Ag over 1.3 metres. This additional information will aid in delineation drilling of La Dura once the surface program begins.

"The identification of high grades of gold and silver mineralization in the Estrella vein is a key development for the Potrero project as the vein is approximately 500 metres southwest of the main Dos de Mayo structure that hosts the three principal mines on the property, and it significantly opens up the size of the mineralized system, both laterally and vertically," stated Robert Archer, Pinnacle's president and chief executive officer. "At surface, La Estrella sits at an elevation of 1,880 masl (metres above sea level) whereas Dos de Mayo is predominantly exposed between 1,490 and 1,570 masl, suggesting that there could be up to 400 metres of vertical continuity of the epithermal system preserved below La Estrella. Geologically, the vein exhibits brecciated, lattice bladed and banded textures, and contains substantial amounts of clay minerals such as kaolin, with red, orange and lemon-yellow oxides, all features that typically occur in the upper parts of a low-sulphidation epithermal system. La Estrella is developing into an important drill target once permits are in place.

Similarly, the identification of significantly higher-grade gold-silver mineralization in outcrop at La Dura 2 has more than tripled the known strike length of this mineralized zone. Given the limited extent and orientation of the underground workings here, this zone will be drilled from surface as soon as possible."

On January 13, 2026, Pinnacle Silver and Gold Corp. has provided an update on progress at the high-grade El Potrero gold-silver project in Durango, Mexico. Having just signed the agreement at the end of February, 2025, to acquire up to a 100-per-cent interest, the company has made significant progress in advancing the project with the goal of fast-tracking it to production and capitalizing on high precious metal prices.

"Two thousand twenty-five was a pivotal year for Pinnacle with the rapid progress towards production on the Potrero project," stated Robert Archer, Pinnacle's president and chief executive officer. "After only 10 months on the project, we have established a substantial high-grade epithermal gold-silver system and are ready to initiate underground delineation drilling to be followed by surface drilling to fill in gaps and test new targets. Metallurgical testwork is continuing and discussions are progressing for an offtake agreement to secure production financing. Project evaluations are also ongoing, with the goal of making another acquisition this year. We look forward to continued progress through 2026 and to keeping shareholders up to date on the company's development."

On January 06, 2026, Pinnacle Silver & Gold Corp. announced that it interprets multiple new targets from lidar survey at El Potrero.

The airborne lidar (light detection and ranging) survey recently flown over Pinnacle Silver and Gold Corp.'s high-grade El Potrero gold-silver project in Durango, Mexico (see Pinnacle's news release of Nov. 24, 2025) has confirmed known structural trends, outlined previously unknown structures, and identified a total of 64 adits, six shafts and 51 prospecting pits on the two claim blocks comprising the project.

"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 and chief executive officer. "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 per cent of the property. As such, we are adding to our geological team to follow up on these new targets."

On the northern, or El Potrero, claim block, the majority of the three 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 predate the northwesterly trend and are host to the Ag-Pb-Zn-Au (silver-lead-zinc-gold) veins of the Topia mine, 13 kilometres to the southwest.

On December 18, 2025, Pinnacle Silver and Gold Corp. announced that it has closed a first tranche of the non-brokered private placement announced on November 25, 2025 (the “Offering”) for gross proceeds of $1,067,532.94. The first tranche consisted of 7,268,171 units (the "Units") with each Unit, priced at $0.14, comprising one common share (“Share”) in the capital of the Company and one-half share purchase warrant ("Warrant"). Each whole Warrant shall be convertible into an additional Share at an exercise price of $0.20 for a period of 24 months from the date of issuance.

The net proceeds raised from the Offering will be used to advance the high-grade El Potrero gold-silver project in Durango, Mexico, for project evaluations, and for general working capital.

On December 15, 2025, Pinnacle Silver and Gold Corp.'s geological team, led by Jorge Ortega, qualified person, has prepared an inaugural underground drilling program for the high-grade El Potrero gold-silver project in Durango, Mexico. Systematic underground channel sampling has been conducted since acquiring the project at the end of February and comprises 773 samples in the three historic mine workings along 500 metres of the Dos de Mayo epithermal vein system. This work has identified several shoots of high-grade gold-silver mineralization in the three mines (see Pinnacle news releases of June 2, July 22, Sept. 9 and Nov. 12, 2025), with individual grades up to 85.1 grams per tonne gold and 520 grams per tonne silver. Several hundred surface channel samples above the historic mines grading up to 37.4 grams per tonne gold and up to 2,280 grams per tonne silver (see Pinnacle news release of June 2, 2025) imply continuity of the mineralization to surface.

As the underground sampling was limited to the extent of the mine workings, detailed drilling is necessary to determine the ultimate size, shape and grade of the mineralized zones. Consequently, Pinnacle's geological team has compiled the results and created 3-D models of the Dos de Mayo vein and the exposed mineralization in the three mines in order to create a program of systematic drilling, whereby the vein structure will be tested every 12.5 metres along strike and vertically. As the holes will be collared either in or immediately adjacent to the vein structure, holes will be relatively short, in the range of 20 to 25 metres in length. At present, it is anticipated that the entire program will comprise approximately 2,600 metres in 112 holes and take about six weeks to complete.

"The underground drilling will be a significant step in the development of the Potrero project," stated Robert Archer, Pinnacle's president and chief executive officer. "It is not common that the first drill program on a new project is underground. However, we are fortunate to have good access to at least some of the mineralization through the historic mine workings and this detailed program will essentially be delineation drilling rather than exploration.

"With the results of this program, we will gain a very good understanding of the principal mineralized zones such that we can begin putting together a preliminary mine plan. Follow-on surface drilling can then test the areas between the mine workings in addition to less developed veins like El Capulin and La Estrella that are being sampled for the first time."

A certain amount of development work will be required in the historic workings to create enough room for the drill set-ups and make sure that the drillers will have a safe working environment. This work will begin early in the new year and will take about one month to complete, with drilling to follow as soon as possible.

On December 10, 2025, Further to the TSX Venture Exchange bulletin dated Feb. 26, 2025, the exchange has accepted documentation for the remaining finder's fee payable to an arm's-length party.

On November 25, 2025, Pinnacle Silver and Gold Corp. is arranging a non-brokered private placement to raise gross proceeds of up to $2.52-million. The placement will consist of up to 18 million units with each unit, priced at 14 cents, comprising one common share in the capital of the company and one-half share purchase warrant. Each whole warrant shall be convertible into an additional share at an exercise price of 20 cents for a period of 24 months from the date of issuance. Finders' fees consisting of 6 per cent in cash commission and 6 per cent in non-transferable finders' warrants may be paid in connection with the offering. Each finder's warrant entitles the holder to acquire one common share at 20 cents per share over a 24-month period. The company expects the offering to close on or about Dec. 19, 2025.

The net proceeds raised from the offering will be used to advance the high-grade El Potrero gold-silver project in Durango, Mexico, for project evaluations, and for general working capital.

On November 24, 2025, Pinnacle Silver and Gold Corp. has flown an airborne lidar survey over the high-grade El Potrero gold-silver project in Durango, Mexico. The survey covered the entire 11-square-kilometre property and was flown by Eagle Mapping Ltd. of Langley, B.C. Reprocessing and interpretation of the data will be conducted by GeoCloud Analytics of Melbourne, Australia, and will take approximately two weeks, with final results available by early to mid-December.

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- to 30-centimetre-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- to 15-centimetre resolution that will assist in surface exploration and planning of infrastructure upgrades.

"Although we have been able to follow and map out the Dos de Mayo vein system along strike for approximately 1,600 metres so far, our geologists are restricted by the amount of outcrop exposure," stated Robert Archer, Pinnacle's president and chief executive officer. "The lidar survey should allow us to connect the dots along this structural trend and allow us to better define not only the main vein but parallel and splay veins nearby. This knowledge, along with additional features such as flexures and fault offsets in the vein structures, will be crucial for interpreting the geological environment and planning the surface drill program. In addition, lidar is known for its ability to detect subtle and sometimes buried features such as old mine workings, overgrown pits and trenches that could lead to the discovery of previously unknown mineralization."

On November 12, 2025, Pinnacle Silver and Gold Corp. provided the sampling results from the historic La Dura mine at the high-grade El Potrero gold-silver project in Durango, Mexico. The identification of another zone of gold-silver extends the mineralized strike length along the Dos de Mayo vein structure to almost 500 metres, with significant gaps between the three principal mines that will have to be drill-tested ( see map below ), thereby increasing the potential. The Dos de Mayo vein has never been previously drilled.

The La Dura mine consists of a main adit that follows the vein for approximately 60 metres along strike to the northwest of the portal and two smaller adits about 10 metres above and to the southeast of the main adit. These two smaller adits, one of which is consistently mineralized, are collectively called La Dura 2. There has been less underground development at La Dura than at either of the Pinos Cuates or Dos de Mayo mines and channel sampling comprises only 146 of the 722 samples taken underground to date on the project. Of those 146 samples, 40 were taken from the two small adits. The mineralized zone identified was sampled by six composite channels along an exposed 12 metre strike length, and has an average width of 1.3 metres and average grades of 1.98 g/t Au and 98 g/t Ag, with individual grades up to 4.51 g/t Au and 269 g/t Ag over 0.5 metres. Very fine visible gold was observed in places. Given that only 12 metres of the mineralized zone is exposed, there is significant potential to expand this with additional mine development and drilling.

“The discovery of this third zone of gold-silver mineralization along the Dos de Mayo vein is further evidence of the repeatability of these zones along strike ,” stated Robert Archer, Pinnacle’s President & CEO. “It appears that the main La Dura adit was developed in the wrong direction at that particular elevation, as it returned only anomalous grades, and the mineralization exposed at La Dura 2 was likely discovered later as it has not been developed any further than this small exposure. As we know that there is some grade variability within the system, the 12 metre strike length and slightly lower grades than we have seen at the other mines suggests only that this exposure has just scratched the surface of this zone, and additional work will be needed to determine the ultimate extent of the mineralization. These preliminary grades at La Dura 2 are still comparable to other low-sulphidation epithermal systems in Mexico and serve to underscore the high-grade nature of the gold-silver mineralization defined to date on the project.”

On October 30, 2025, Pinnacle Silver and Gold Corp. announced that it will be participating in the 51st Annual New Orleans Investment Conference at the Hilton New Orleans Riverside November 2 - 5, 2025.

The New Orleans Investment Conference gathers some of the world’s brightest and most successful analysts, newsletter writers and investors. This year’s event will highlight all major asset classes, including Gold and Silver.

On October 28, 2025, Pinnacle Silver and Gold Corp. announced the positive results from the preliminary scoping metallurgical tests for the high-grade El Potrero gold-silver project in Durango, Mexico including excellent gold recoveries up to 96.79% and averaging 95.09%. Highlights:

• Three samples from the mineralized zone within the Pinos Cuates underground mine were sent to the SGS Lab in Durango, Mexico for grinding, bottle roll cyanide leach and gravity tests.
• Initial grind calibration tests in a ball milling application achieved a target grind of 80% passing 270 mesh (53 micron) particle size.
• Bottle roll cyanide leach tests resulted in consistently high gold recoveries of 92.81%, 95.68% and 96.79%, averaging 95.09% . Silver recoveries were lower and more variable, at 41.41%, 73.53% and 49.11%, with an average of 54.68%, indicating the presence of a more complex mineralogy and a need for further test work such as extended leach times.
• Average unoptimized reagent consumption was 0.71 kg/t NaCN and 1.62 kg/t CaO, both within expected ranges for a preliminary test.
• Initial gravity tests utilising a Knelson concentrator and Mozley table resulted in variable recoveries ranging from 29.1% to 76.38% for gold and 3.98% to 15.91% for silver.

“We are very pleased with the results from this preliminary round of metallurgical tests , especially for gold recoveries, and considering that there were only three samples from one of the three historic mines,” stated Robert Archer, Pinnacle’s President & CEO. “These tests were run using simple baseline parameters and without any optimization. The results indicate that we need to conduct mineralogical tests on the mineralization to determine the nature of the gold and silver occurrences. While it is likely that gold occurs either as free particles or in electrum, silver can occur in electrum, silver sulphides or silver sulphosalts. Once this has been established, further testing will be able to fine tune the metallurgical processes in order to increase recoveries, particularly for silver. Metallurgical testing is an iterative process, and it is expected that sampling of the other mines on the property will result in further variations. However, this is the whole point of the testing as we aim to maximize recoveries and streamline the flow sheet prior to rebuilding the plant.”

On October 21, 2025, Pinnacle Silver and Gold Corp. has appointed Carlos Castro Villalobos, Ing, as project manager for the high-grade El Potrero gold-silver project in Durango, Mexico. Mr. Castro Villalobos is a highly experienced mining engineer, having built and operated mines for a number of companies throughout Mexico.

In addition, the qualified person (QP) for the project and author of the National Instrument 43-101 report, Jorge Ortega, PGeo, continues in the role of exploration manager and is already actively supervising the company's geological team, which has taken more than 1,000 surface and underground samples at the site, and is building a solid understanding of the controls on gold-silver mineralization in this high-grade low-sulphidation epithermal system.

"I am excited to be working with both Carlos and Jorge again," stated Robert Archer, Pinnacle's president and chief executive officer. "As former general manager of the Guanajuato mine and exploration manager for Great Panther Silver, respectively, they both played integral roles in the growth of that company. Our current mine geologist also used to work at the Guanajuato mine during that time. As we move forward towards a production scenario at El Potrero, it is gratifying to be able to draw on their expertise in building a new team, to maximize the chance of success."

On September 24, 2025, Pinnacle Silver and Gold Corp.'s continuing surface mapping and sampling, in conjunction with the previously announced high-grade gold-silver mineralization in the historic Pinos Cuates and Dos de Mayo mines, is revealing the presence of a robust low-sulphidation epithermal system at the Potrero project in Durango, Mexico. Not only has the surface sampling extended the underground mineralization to surface, but a parallel vein some 200 metres to the southwest, called El Capulin, is demonstrating good continuity of gold-silver mineralization. Highlights:

• Surface sampling above the Pinos Cuates and Dos de Mayo mines has extended high-grade gold-silver mineralization over a vertical distance of up to 80 metres;
• Silver grades of 2,280 grams per tonne and 1,444 g/t at surface imply a potential vertical zonation with silver increasing upward in the system;
• A newly defined mineralized vein called El Capulin lies parallel to, and approximately 200 metres away from, the Dos de mayo vein and has been traced and sampled for approximately 375 metres along strike with grades up to 6.27 g/t Au (gold) and 99 g/t Ag (silver);
• The identification of El Capulin and the vertical extension of gold-silver mineralization have significantly increased the potential of the project.

"We are extremely pleased with how the combination of underground and surface sampling is coming together to define a strong, well-defined and high-grade vein system at El Potrero," stated Robert Archer, Pinnacle's president and chief executive officer. "On the Dos de Mayo trend, the higher silver grades at surface continue to suggest there may be some vertical zonation, with silver increasing upward. As one moves uphill to El Capulin, the continued presence of gold-silver mineralization up to 1,720 masl infers that mineralization here could extend downward to similar levels seen on the Dos de Mayo structure, or a vertical distance of approximately 200 metres. These observations are consistent with low sulphidation systems in the Topia district and elsewhere in Mexico, and bode well for the potential to develop significant zones of mineralization."

On September 09, 2025, Systematic underground channel sampling in the historic Dos de Mayo mine at Pinnacle Silver and Gold Corp.'s El Potrero project in Durango, Mexico, is providing a good look at the gold-silver distribution within the known mineralized zone. Fifty-three channel samples, in 13 composite channels, were taken within a raise (inclined tunnel approximately 1.5 metres in diameter) connecting two levels 25.5 metres apart. Composite assays up to 11.2 grams per tonne gold (g/t Au) and 179 grams per tonne silver (g/t Ag) over 3.5 metres, 15.55 g/t Au and 222 g/t Ag over 1.1 metres, and 11.93 g/t Au and 190 g/t Ag over 1.4 metres (see table 1) were obtained, with individual assays up to 27.6 g/t Au and 366 g/t Ag over 0.6 metre. The weighted average of mineralized composites within the raise assayed 6.43 g/t Au and 110 g/t Ag.

"As at the historic Pinos Cuates mine (see news releases for June 2 and July 22, 2025), the existing underground workings at Dos de Mayo are giving us an important understanding of the nature of the gold-silver mineralization at El Potrero," stated Robert Archer, Pinnacle's president and chief executive officer. "What we are seeing is consistent with these low-sulphidation epithermal systems, where pockets of high-grade mineralization (called clavos in Mexico) occur within a defined horizon, likely consistent with the boiling zone of the hydrothermal fluids. At both mines, the main level appears to have been the haulage level as they are mostly unmineralized, although sporadic higher-grade assays were received. Despite the lack of historic production records, it seems likely that the haulage levels were constructed below, and outside of, the mineralized horizon.

"It is important to note that sample lengths do not represent the width of the vein or the extent of the mineralization. They are simply the composite lengths of the individual channels sampled end to end and may be taken at any angle to the trend of mineralization, depending upon what is exposed underground. While the systematic and close-spaced nature of the sampling does give a representative characterization of the mineralization, the full extent of this particular clavo, as at Pinos Cuates, is as yet unknown and will require drilling to determine.

"On a larger scale, the underground sampling is providing crucial information to better understand the distribution of gold and silver mineralization such that we can correlate with the surface sampling within the collective 500-metre strike length of the historic mines and then extrapolate along the entire 1,600-metre strike length that we have defined to date. We are currently in the planning stages for an underground drilling program at all three main mines that will effectively be delineation drilling on a fairly detailed scale. Further information on that will be released in due course."
