Pinnacle Samples up to 12.2 g/t Gold Equivalent and Commences Field Work at El Potrero Gold-Silver Project

(TheNewswire)

VANCOUVER, BRITISHCOLUMBIA, March 18, 2025 – TheNewswire- (TSXV:PINN, OTC: NRGOF, Frankfurt: X6C) – Pinnacle Silver and GoldCorp. (" Pinnacle " or the“ Company ") is pleased to provide furtherdetails on the preliminary underground sampling program that wasconducted as part of the due diligence work on the recently acquired high-grade gold-silver El Potrero property in Durango, Mexico (see Pinnacle newsreleases dated February 24 and 25, 2025).  The Company also announces that Phase Ifield work has commenced on the project.

Preliminary sampling ofmineralized veins containing grey-black ginguro bands (very finegrained silver-gold mineralization) in the Pinos Cuates Mine returnedan arithmetic average from four chip channel samples (see Table 1below) of 8.04 g/t gold (Au) and 146 g/t silver (Ag) (9.70 g/t AuEquivalent or 853 g/t Ag Equivalent 1 ), consistentwith the historic production grades reported verbally by the vendors,and the historic resource estimate of 45,561tonnes at 8.0 g/t Au and 186 g/t Ag (10.1 g/t AuEq or 890 g/t Ag Eq 1 ). These resourcesare historical in nature and Pinnacle is not treating these estimatesas current mineral resources as a qualified person on behalf ofPinnacle has not done sufficient work to classify them as currentmineral resources.

“Having just recently closed the acquisition of thestaged option on the Potrero Property, we are wasting no time in‘hitting the ground running’ on this exciting project,” statedRobert Archer, Pinnacle’s President & CEO.  “Not only did ourdue diligence sampling confirm the high-grade nature of thegold-silver mineralization, but the historic workings stretching overa 500 metre strike length and the absence of any drilling or othermodern exploration implies significant potential for resourcedevelopment on a strong epithermal vein system.  Furthermore, we willimmediately commence cleaning the processing plant in order to puttogether a budget and schedule to make it operational onceagain.”

As part of Pinnacle’s due diligence on the property,non-systematic sampling of the main exposed structures in undergroundworkings at the Dos de Mayo, Pinos Cuates and La Dura historic mineswas undertaken during two visits in October and December of 2024 (seeFigure 1).  The lack of any detailed surface or underground maps andthe general inaccessibility of most of the old stopes containing themineralization underground led to the non-systematic nature of thesampling.  Vein exposures underground were typically less than twometres, thereby limiting the width of the veins that could be sampled. As such, professional mining contractors are being brought in torender these areas safe for a more systematic sampling program.

Assays from the first visit indicated that the veinsystem is clearly gold- and silver-bearing, while the second visitallowed for the more precise identification of mineralized zoneswithin the veins, particularly in the Pinos Cuates workings where an‘upper’ level, approximately 10 metres above the previous visit,was examined and sampled, yielding the results in Table 1 above. Values in the 35 underground samples ranged from 0.047 to 9.32 g/tAu and <2 to 254 g/t Ag.  Importantly, there is no significantamount of base metals or any deleterious elements that could impactthe metallurgy.

Following the cleaning of the underground workings, thevein system will be surveyed, mapped and systematically sampled inorder to determine the structural controls on gold-silvermineralization as the highest grades tend to occur in ‘shoots’. Once these are better defined, a diamond drilling program can beplanned to systematically test these areas for continuity.  As nodrilling has been conducted previously, the vein system is open in alldirections.

While the underground workings are being rehabilitated,surface mapping will get underway to trace out the vein system andgain a better understanding of the geological setting.  Initially,this work will focus on the area above the historic mines then workout along strike to the northwest and southeast.  From observationsmade during the due diligence period, the veins appear to splay alongstrike and several parallel veins exist both on the property and onneighbouring ground, suggesting that the system may be more extensivethan initially realized.

Given the importance of structure in these types ofvein systems, a LiDAR (Light Detection and Ranging) survey is beingplanned for the entire property.  LiDAR is a remote-sensing and lasertechnology that ‘sees’ through overburden and maps out the rocksubsurface in a way that allows for the interpretation of structuralfeatures that can be important in controlling gold-silvermineralization.  This interpretation will also be used in theplanning of upcoming drill programs.

Roads on the property are being rehabilitated and thecampsite will be cleaned and rebuilt.  In due course, discussionswill be held with the federal electrical commission to extend thepower line to the plant site, a distance of only about threekilometres.

QA/QC

The assay results contained in this news release havebeen prepared in accordance with National Instrument 43-101 Standardsof Disclosure for Mineral Projects ("NI 43-101").  Pinnaclehas implemented industry standard practices for sample preparation,security and analysis given the stage of the Project.  This hasincluded common industry QA/QC procedures to monitor the quality ofthe assay database, including inserting certified reference materialsamples and blank samples into sample batches on a predeterminedfrequency basis.

Non-systematic chip channel sampling was completedacross the exposed mineralized structures using a hammer and maul. The protocol for sample lengths established that they were notlonger than two metres or shorter than 0.3 metres.  The veins tend tobe steeply dipping to vertical, and so these samples are reasonablyclose to representing the true widths of the structures.  Sampleswere collected along the structural strike or oblique to the mainstructural trend.

All samples were bagged in pre-numbered plastic bags;each bag had a numbered tag inside and were tied off with adhesivetape 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 plasticties and delivered directly to the SGS laboratory facility in Durango,Mexico for preparation and analysis.  The lab is accredited toISO/IEC 17025:2017.  All Samples were delivered in person by thecontract geologist who conducted the sampling under the supervision ofthe QP.

SGS sample preparation code G_PRP89 including weightdetermination, crushing, drying, splitting, and pulverizing was usedfollowing industry best practices where all samples were crushed to75% less than 2 mm, riffle split off 250 g, pulverized split to>85% passing 75 microns (?m).  All samples were analyzed for goldusing code GA_FAA30V5 with a Fire Assay determination on 30g sampleswith an Atomic Absorption Spectography finish.  An ICP-OES analysispackage (Inductively Coupled Plasma - Optical Emission Spectrometry)including 33 elements and 4-acid digestion was performed (codeGE_ICP40Q12) to determine Ag, Zn, Pb, Cu and other elements.

About the Potrero Property

El Potrero is located in the prolific Sierra MadreOccidental of western Mexico and lies within 35 kilometres of fouroperating mines, including the 4,000 tonnes per day (tpd) CiénegaMine (Fresnillo), the 1,000 tpd Tahuehueto Mine (Luca Mining) and the250 tpd Topia Mine (Guanajuato Silver).

High-grade gold-silvermineralization occurs in a low sulphidation epithermal breccia veinsystem hosted within andesites of the Lower Volcanic Series and hasthree historic mines along a 500 metre strike length.  A historicresource based upon underground sampling of those three mines isreported to consist of 45,561 tonnes at 8.0 g/t gold and 186 g/tsilver. The property has been in privatehands for almost 40 years and has never been drilled or explored bymodern methods, leaving significant exploration potential.

A 100 tpd plant on site can be refurbished / rebuiltand historic underground mine workings rehabilitated at relatively lowcost in order to achieve near-term production once permits are inplace. The property is road accessible with a power line within threekilometres.  Surface rights over the plant and mine area areprivately owned (no community issues).

Pinnacle will earn an initial 50% interest immediatelyupon commencing production.  The goal would then be to generatesufficient cash flow with which to further develop the project andincrease the Company’s ownership to 100% subject to a 2% NSR.  Ifsuccessful, this approach would be less dilutive for shareholders thanrelying on the still challenging equity markets to finance the growthof the Company.
