Pinnacle Clarifies Previous News Release
VANCOUVER, BRITISH COLUMBIA, July 22, 2025 (TSXV: PINN, OTC: PSGCF, Frankfurt: P9J) –
Pinnacle Silver and Gold Corp. ("Pinnacle" or the “ Company") announces that it is clarifying its
previous news release at the request of CIRO. The Company ’s continuing underground channel
sampling in the historic Pinos Cuates mine at the El Potrero Project in Durango, Mexico has returned
multiple high-grade assays up to 85.1 grams/tonne gold (g/t Au) and 520 grams/tonne silver (g/t
Ag) over 0.5 metres. A raise (inclined tunnel) between the main and upper levels of the mine provided
additional access to the highest grade portion of the vein reported in Pinnacle news release of June 2,
2025 that returned composite channel assays of up to 19.4 g/t Au and 266 g/t Ag over 4.1 metres.
The recent installation of metal ladders provided new and safe access for the geological crew to sample
a different portion of this zone on a sub-level, resulting in composite channel assays of 50.3 g/t Au and
269 g/t Ag over 1.7 metres, 34.6 g/t Au and 228 g/t Ag over 1.0 metre, 9.84 g/t Au and 141 g/t Ag
over 4.2 metres and 8.33 g/t Au and 154 g/t Ag over 1.8 metres.
“We continue to be impressed by the tenor and consistency of the grades at Pinos Cuates,“ stated
Robert Archer, Pinnacle’s President & CEO. “While the underground workings give us access to a
portion of the mineralized zone, we still don’t know its extent. In these low -sulphidation epithermal
systems, pockets of high -grade mineralization typically pinch and swell both along strike and up and
down dip. The underground work is allowing us to characterize the mineralization such that we will be
better able to find and delineate other zones within the Dos de Mayo vein system. Some follow up
sampling on these results has already been conducted and w e are planning an underground drilling
program to better define the extent of this mineralized zone as it can be difficult to drill through
underground workings from surface.”

A total of 42 channel samples were taken in 16 composite channels in the raise. Grades ranged from
0.105 to 85.1 g/t Au and 9 to 520 g/t Ag. All samples were assayed for gold, silver and a suite of 32
other elements, including copper, lead and zinc. However, the base metal assays were consistently
low, confirming that this is a precious metal dominant system.
The Pinos Cuates mine is the middle of three historic mines along a 500 metre strike length on the Dos
de Mayo vein system on the Potrero property. Underground sampling is continuing at the Dos de Mayo
mine to the southeast and will be followed by sampling of the La Dura mine to the northwest. The vein
system has been traced on surface for 1,600 metres and there are other parallel and splay veins that
are being further defined as the property has never been systematically explored. The mine workings
are currently being accurately surveyed such that a 3D model can be created.
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 m aul. 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. T he 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.
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.
