Drillhole Orientation Details

Limo Butte Geology & Antimony Summary
A review of historical geochemical and drilling data at the Limousine Butte Project has identified multiple areas with strong gold-antimony potential. These zones correlate closely with outcrops of the Devonian Pilot Shale, the primary host rock for Carlin-type gold mineralization in the area. Positive gold grade at Limousine Butte is typically associated with silicification and the formation of jasperoid breccias within the Pilot Shale, an alteration feature also observed in the positive antimony results.

Through the Project data review, the Company uncovered reports detailing two small-scale historic mining operations at the Nevada Antimony Mine and Lage Antimony Prospect within the Limo Butte Project boundary. The Nevada Antimony Mine featured two prospect pits that extracted stibnite (formula: Sb ₂ S ₃ ) from a hydrothermal breccia. The Lage Antimony Prospect reported historical additional prospect pits extracting antimony.

Historical geochemical rock chip sampling within the past-producing Golden Butte pit from a Brigham Young University (‘BYU’) Thesis study produced numerous results that exceeded 1% antimony in jasperoid breccias (see Figure 1). Several results were greater than 5% antimony, including a sample of 9.6% antimony with visible stibnite and stibiconite . BYU Thesis Report

US Executive Order – Announced March 20, 2025
The Company is pleased to report the recent, 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 no domestically mined 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’, NASDAQ:PPTA, TSX:PPTA) 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 the technical development and permitting has led to US$75 million in Department of Defense (‘DOD’) awards, and 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))

‘We continue to make excellent progress in moving the Potrero Project forward,’ stated Robert Archer, Pinnacle’s President & CEO.  ‘I joined our consultants in a comprehensive site review last week that provided valuable guidance for permitting and a plant re-build and we are encouraged on both fronts.  In parallel, our geological team is making significant strides in their interpretation of the gold-silver mineralizing system at El Potrero and we are commencing plans for an underground drilling program in addition to surface drilling.  To date, we have taken in excess of 600 rock samples from underground and surface, with the latest batch in the SGS lab in Durango, and are starting to get a good understanding of the geology that will be critical in the planning stages going forward.’

Geological Program

A review was conducted with the geological team whereby the importance of a quartz-feldspar (+/- biotite) porphyry dyke is being recognized as it follows the same structure that hosts the mineralized quartz breccia vein system (see Figure 2).  These types of dykes, and their potential association with rhyolite domes, are commonly associated with epithermal systems.

The dyke is pre-mineral as evidenced by the presence of quartz veinlets and associated weak gold-silver values within.  It may have provided a competency contrast with the host andesitic volcanics and/or opened up the structure for the injection of mineralizing fluids.  As such, the presence of the dyke appears to be an important component in localizing gold-silver mineralization within the breccia and may well become a critical exploration feature.

In particular, it was observed that some of the underground workings are entirely within the dyke and the presence of potentially mineralized vein breccia, presumably in the wall of the workings, needs to be drill-tested.  The possibility of doing this via an underground drilling program is currently being assessed as it could be faster and cheaper than a surface drill program.

Follow-up sampling is being conducted in the areas of high-grade gold-silver mineralization that has been identified to date, including the upper level of the historic Pinos Cuates mine (see Figure 3) where composite channel samples returned up   19.4 grams per tonne gold (g/t Au) and 266 grams per tonne silver (g/t Ag) over 4.1 m etres, with individual samples returning up to 37.3 g/t Au and 346 g/t Ag ( see Pinnacle news release of June 2, 2025 ).

Additional channel sampling is also being conducted in areas that were previously restricted by accessibility that has now been improved by the installation of metal ladders.  First pass sampling of the Dos de Mayo mine is complete, with 167 samples taken and submitted to the SGS lab in Durango.  Underground mapping and sampling will now progress to the easternmost La Dura and La Dura 2 workings, where fine-grained visible gold and ginguro (grey-black bands of electrum and silver sulphides) were observed on the site visit.

Surface prospecting, mapping and sampling along the main Dos de Mayo vein system is continuing, with cleaning and sampling of historical trenches being conducted in areas of interest such as the old pit with vein material containing visible gold and ginguro that assayed 13.2 g/t Au and 2,280 g/t Ag and 5.2 g/t Au and 745 g/t Ag in two grab samples (see Pinnacle news release of June 2, 2025 ).

A program of combined underground and surface diamond drilling is being devised in order to systematically test the Dos de Mayo vein system.  Underground drilling would consist of short (10-20 metres), closely spaced (10-15 metres) holes drilled into the walls of the underground workings and would be designed to test the width, continuity and grade of the breccia vein.  Results would be used to guide future mine development.  Surface holes would be more widely spaced (potentially 50 metres) and would be designed to give a more complete cross-section through the 500 metre mine area as well as test the continuity of the vein structure and mineralization along strike of the historic mines.  Further details will be provided in due course.

Plant Assessment

With access roads to the project and the area around the plant having been completely cleaned up, an inspection was conducted by a plant consultant to assess the approximate cost and schedule to get it ready for production again.  While a final report will be submitted to the company within approximately 3-4 weeks, it was determined that the basic infrastructure (framework, excavation and civil pads) appears to be sound, thereby significantly reducing both costs and time to get it production-ready.  As such, future costs required will be focused on specific equipment such as new/refurbished crushers, ball mill, pumps, leaching and solution recovery equipment, and the Merrill Crowe circuit, etc.  This will ensure required plant capacity and reliability during operation.

Metallurgical testing will also be undertaken and once all the equipment has been sized and a new flowsheet designed, water balance and connected power requirements will be determined that will, in turn, provide the basis for permitting and discussions with the Comision Federal de Electricidad – the federal electrical commission.  The existing power line comes to within about three kilometres of the plant, but a new or upgraded substation may need to be established to provide sufficient power to the site.  Potential areas for a dry-stack tailings storage facility were also examined as a means of water recovery and conservation.

Further details will be provided as the assessment progresses.

Permitting

A permit consultant was taken to the project to initiate a site review for the purpose of permitting near-term diamond drilling, mid-term mine development and site preparation, and future production.  As anticipated, the Company was advised that the previous disturbance of the site by historic activity will significantly speed up and simplify the permitting process.  Guidelines on the requirements for baseline studies, to include extensive photos, soil and water samples, etc. were discussed and a compilation of this material has already been initiated.  A more formal proposal from the consultant will be submitted to the Company within the next two weeks, whereby the permitting process can get underway.

At a higher level, meetings were held with the Company’s corporate and environmental lawyers to discuss the anticipated process of completing and filing permit applications with the authorities in such a way as to minimize any potential delays.

QA/QC

The technical results contained in this news release have been reported in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects (‘NI 43-101’).  Pinnacle has implemented industry standard practices for sample preparation, security and analysis given the stage of the Project.  This has included common industry QA/QC procedures to monitor the quality of the assay database, including inserting certified reference material samples and blank samples into sample batches on a predetermined frequency basis.

The systematic chip channel sampling was completed across exposed mineralized structures using a hammer and maul.  The protocol for sample lengths established that they were not longer than two metres or shorter than 0.3 metres.  The veins tend to be steeply dipping to vertical, and so these samples are reasonably close to representing the true widths of the structures.  Samples were collected along the structural strike or oblique to the main structural trend.

All samples were bagged in pre-numbered plastic bags; each bag had a numbered tag inside and were tied off with adhesive tape and then bulk bagged in rice bags in batches not to exceed 40 kg.  They were then numbered, and batch bags were tied off with plastic ties and delivered directly to the SGS laboratory facility in Durango, Mexico for preparation and analysis.  The lab is accredited to ISO/IEC 17025:2017.  All Samples were delivered in person by the contract geologist who conducted the sampling under the supervision of the QP.

SGS sample preparation code G_PRP89 including weight determination, crushing, drying, splitting, and pulverizing was used following industry best practices where all samples were crushed to 75% less than 2 mm, riffle split off 250 g, pulverized split to >85% passing 75 microns (μm).  All samples were analyzed for gold using code GA_FAA30V5 with a Fire Assay determination on 30g samples with an Atomic Absorption Spectography finish.  An ICP-OES analysis package (Inductively Coupled Plasma – Optical Emission Spectrometry) including 33 elements and 4-acid digestion was performed (code GE_ICP40Q12) to determine Ag, Zn, Pb, Cu and other elements.

Qualified Person

Mr. Jorge Ortega, P. Geo, a Qualified Person, and independent from Pinnacle, 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.  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.  (These resources are historical in nature and Pinnacle is not treating these estimates as current mineral resources as a qualified person on behalf of Pinnacle has not done sufficient work to classify them as current mineral resources.)  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 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.  Surface rights covering the plant and mine area are privately owned (no community issues).

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 district-scale exploration for precious metals in the Americas.  The addition of the high-grade Potrero gold-silver project in Mexico’s Sierra Madre Belt complements the Company’s project portfolio 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.

Although Charbone believes that the expectations reflected in the forward-looking statements are reasonable, forward-looking statements involve risks and uncertainties, and undue reliance should not be placed on forward-looking statements, as unknown or unpredictable factors could cause actual results to be materially different from those reflected in the forward-looking statements. The forward-looking statements may be affected by risks and uncertainties in the business of Charbone. These risks, uncertainties and assumptions include, but are not limited to, those described under ‘Risk Factors’ in the Corporation’s Filing Statement dated March 31, 2022, which is available on SEDAR at www.sedar.com; they could cause actual events or results to differ materially from those projected in any forward-looking statements.

Except as required under applicable securities legislation, Charbone undertakes no obligation to publicly update or revise forward-looking information.
