TORONTO, ON / ACCESS Newswire / August 6, 2026 / Silver Storm Mining Ltd. ("Silver Storm" or the "Company")
(TSXV:SVRS)(OTCQX:SVRSF)(FSE:SVR), is pleased to announce drill results from the diamond drilling program at the
Company's 100%-owned La Parrilla Silver Mine Complex ("La Parrilla") located in Durango State, Mexico. Drillhole results in
this release are from the Rosarios Zone within the past-producing Rosarios mine.
Key highlights include:
Hole IDP-RO-26-004 returned 215 g/t Ag.Eq over 11.90 metres ("m") (ETW 11.9 m).
Hole IDP-RO-26-007 returned 200 g/t Ag.Eq(1,2) over 15.35 m (ETW(3) 13.3 m).
Hole IDP-RO-26-005 returned 297 g/t Ag.Eq over 7.30 m (ETW 7.2 m), 160 g/t Ag.Eq over 4.85 m (ETW 4.8 m), and
196 g/t Ag.Eq over 3.85 m (ETW 3.8 m).
Hole IDP-RO-26-002 returned 239 g/t Ag.Eq over 5.90 m (ETW 5.7 m).
Hole IDP-RO-26-008 returned 481 g/t Ag.Eq over 1.65 m (ETW 1.6 m) and 149 g/t Ag.Eq over 4.10 m (ETW 3.9 m).
Hole IDP-RO-26-003 returned 442 g/t Ag.Eq over 1.00 m (ETW 0.9 m).
The infill drill results from the Rosarios Zone highlighted the potential to extend the Indicated Resources by additional
100 m toward the surface along a strike length of 125 m.
Greg McKenzie, President and CEO, stated: "We are pleased to deliver yet another impressive set of drill results, this time
demonstrating the potential to increase the La Parrilla Mineral Resource at the Rosarios Zone. We will continue our 15,000 m
drilling program to grow the resource footprint while operations ramp up at La Parrilla."
Rosarios Zone
The Rosarios Zone has historically been an important part of La Parrilla and is characterized by a sulphide-bearing quartz-
carbonate vein hosted within a fault zone striking west-northwest and dipping 64 degrees to the northeast over a known strike
length of approximately 2 km. The mineralization at Rosarios extends vertically for 900 m, and its true width varies by up to 14
m. The Rosarios vein is located roughly at the northern contact of sediments and granodiorite stock. Stockwork zones are
developed either in the footwall or hanging wall of the Rosarios vein, while vein splays and sulphide replacement zones are
typically developed in the hanging wall. The Rosarios Zone remains open both along strike and at depth.
Table 1 summarizes the results from the 8 infill holes drilled at the Rosarios Zone targeting the oxide mineralization.
Highlights from the near-surface drilling conducted in the western portion of the Rosarios Zone include:
Hole IDP-RO-26-007 returned 200 g/t Ag.Eq over 15.35 m (ETW 13.3 m) in oxide mineralization.
Hole IDP-RO-26-004 returned 215 g/t Ag.Eq over 11.90 m (ETW 11.9 m) in oxide mineralization.
Hole IDP-RO-26-005 returned 297 g/t Ag.Eq over 7.30 m (ETW 7.2 m) in sulphide mineralization, as well as 160 g/t
Ag.Eq over 4.85 m (ETW 4.8 m) and 196 g/t Ag.Eq over 3.85 m (ETW 3.8 m) in oxide mineralization.
Hole IDP-RO-26-002 returned 239 g/t Ag.Eq over 5.90 m (ETW 5.7 m) in oxide mineralization.
Hole IDP-RO-26-008 returned 481 g/t Ag.Eq over 1.65 m (ETW 1.6 m) in oxide mineralization and 149 g/t Ag.Eq over
4.10 m (ETW 3.9 m) in oxide mineralization.
Hole IDP-RO-26-003 returned 442 g/t Ag.Eq over 1.00 m (ETW 0.9 m) in oxide mineralization.
The infill drill results from the Rosarios Zone demonstrate the potential to extend the Indicated Resources by additional 100
m toward the surface along a strike length of 125 m.
Underground rehabilitation and development activities within the past-producing Rosarios mine are underway. All mineralized
intersections reported in this release are proximal to existing infrastructure and development within the mine.
Silver Storm has two underground drill rigs and one surface drill rig in operation to advance the current drilling program. A total
of 115 holes have been completed to date (~13,000 m).

1. The individual grades of the metals that were used as inputs into the metal equivalent Ag.Eq g/t are provided in Table 1.
2. All results in this release are rounded. Assays are uncut and undiluted. Widths are core-lengths, not true widths. Silver
equivalent: Ag.Eq g/t was calculated using commodity prices of US$30.00 /oz Ag, US$2,500 /oz Au, US$0.95 /lb Pb, and
US$1.25 /lb Zn applying metallurgical recoveries of 70.1% for silver and 82.8% for gold in oxides and 79.6% for silver,
80.1% for gold, 74.7% for lead and 58.8% for zinc in sulphides. Metal payable used was 99.6% for silver and 95% for gold
in doré produced from oxides, and 95% for silver, gold, and lead and 85% for zinc in concentrates produced from
sulphides. Cut-off grades considered for oxide and sulphide were 135 g/t Ag.Eq and 115 g/t Ag.Eq, respectively. The cut-
off grades were based on 2017 costs adjusted by the inflation rate and include sustaining costs.
3. Estimated true widths ("ETW") of mineralization have been calculated from core-lengths for drill core where orientation
of the zone is known.
Sample Analysis and QA/QC Program
Silver Storm uses a quality assurance/quality control (QA/QC) program that monitors the chain of custody of samples and
includes the insertion of blanks, duplicates, and reference standards in each batch of samples sent for analysis. The drill core is
photographed, logged, and cut in half, with one half retained in a secured location for verification purposes and one half shipped
for analysis. Sample preparation (crushing and pulverizing) is performed at ALS Geochemistry, an independent ISO 9001: 2001
certified laboratory, in Zacatecas, Mexico and pulps are sent to ALS Geochemistry in Vancouver, Canada for analysis. The entire
sample is crushed to 70% passing -2 mm, and a riffle split of 250 grams is taken and pulverized to better than 85% passing 75
microns. Samples are analyzed for gold using a standard fire assay with Atomic Absorption Spectrometry (AAS) (Au-AA23)
from a 30-gram pulp. Gold assays greater than 10 g/t are re-analyzed on a 30-gram pulp by fire assay with a gravimetric finish
(Au-GRA21). Samples are also analyzed using a 34 element inductively coupled plasma (ICP) method with atomic emission
spectroscopy (AES) on a pulp digested by four acids (ME-ICP61). Overlimit sample values for silver (>100 g/t), lead (>1%), zinc
(>1%), and copper (>1%) are re-assayed using a four-acid digestion overlimit method with ICP-AES (ME-OG62). For silver
values greater than 1,500 g/t, samples are re-assayed using a fire assay with gravimetric finish on a 30-gram pulp (Ag-GRA21).
Samples with lead values over 20% are re-assayed using volumetric titration with EDTA on a 1-gram pulp (Pb-VOL70). No
QA/QC issues were noted with the results reported herein.

Cautionary Note Regarding Forward Looking Statements:
Certain statements in this news release are forward-looking and involve a number of risks and uncertainties. Such forward-
looking statements are within the meaning of the phrase ‘forward-looking information' in the Canadian Securities
Administrators' National Instrument 51-102 - Continuous Disclosure Obligations. Forward-looking statements are not comprised
of historical facts. Forward-looking statements include estimates and statements that describe the Company's future plans,
objectives or goals, including words to the effect that the Company or management and Qualified Persons (in the case of
technical and scientific information) expects a stated condition or result to occur. Forward-looking statements may be identified
by such terms as "believes", "anticipates", "expects", "estimates", "may", "could", "would", "will", or "plan". Since forward-
looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent
risks and uncertainties. Although these statements are based on information currently available to the Company, the Company
provides no assurance that actual results will meet management's expectations. Risks, uncertainties and other factors involved
with forward-looking information could cause actual events, results, performance, prospects and opportunities to differ
materially from those expressed or implied by such forward-looking information. Forward-looking information in this news
release includes, but is not limited to: the future exploration performance at La Parrilla, the timing and extent of current and
future drill programs, the potential dimensions of the Mineral Resource extension at the Rosarios Zone, and the ability to
increase the Mineral Resources therein.
In making the forward-looking statements included in this news release, the Company and Qualified Persons (in the case of
technical and scientific information) have applied several material assumptions, including that the Company´s financial
condition and development plans do not change because of unforeseen events, that future metal prices and the demand and
market outlook for metals will remain stable or improve, management's ability to execute its business strategy and no unexpected
or adverse regulatory changes with respect to La Parrilla. The Company cautions that its decision to potentially restart
operations at La Parrilla, and any related production decisions, are largely based on internal Company data, historical
operating results, reports, and engineering assessments and are not supported by a current mineral reserve estimate prepared in
accordance with NI 43-101, preliminary economic assessments, pre-feasibility studies, or feasibility studies that demonstrate
economic and technical viability. As a result, there is increased uncertainty and a higher degree of economic and technical risk
associated with any such production decision than would be the case if such mineral reserves estimates or studies were
completed and relied upon to support a production decision. No mineral reserves have been established for La Parrilla, and
mineral resources that are not reserves do not have demonstrated economic viability. The absence of mineral reserve estimates
prepared in accordance with NI 43-101, preliminary economic assessments, pre-feasibility studies, or feasibility studies
supporting a production decision increases the uncertainty of achieving any particular level of mineral recovery or the cost of
such recovery and heightens the risks associated with developing a commercially mineable deposit. Historically, projects
advanced without the support of such mineral reserves estimates and studies have experienced a significantly higher incidence of
economic and technical failure. There can be no assurance that production at La Parrilla will commence as anticipated or at all,
or that any anticipated production levels or operating costs will be achieved. A failure to commence production would have a
material adverse effect on the Company's ability to generate revenue and cash flow to fund its operations. Similarly, a failure to
achieve anticipated production costs would have a material adverse effect on the Company's cash flow and future profitability.
Forward-looking statements and information are subject to various known and unknown risks and uncertainties, many of which
are beyond the ability of the Company to control or predict, that may cause the Company's actual results, performance or
achievements to be materially different from those expressed or implied thereby, and are developed based on assumptions about
such risks, uncertainties and other factors set out herein.
Such forward-looking information represents management's and Qualified Persons' (in the case of technical and scientific
information) best judgment based on information currently available. No forward-looking statement can be guaranteed, and
actual future results may vary materially. Accordingly, readers are advised not to place undue reliance on forward-looking
statements or information.
