NEWS RELEASE
SILVER STORM DRILLS 473 g/t Ag.Eq(1,2) OVER 3.6 m AND 137 g/t Ag.Eq OVER 12.0 m,
EXTENDS THE SAN NICOLAS ZONE AT DEPTH
Toronto, Ontario, April 21, 202 6: Silver Storm Mining Ltd. (“ Silver Storm ” or the " Company")
(TSX.V: SVRS | OTCQB: 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, Mexico. Results from the holes (910 metres (“m”)) contained within this release are from
the San Nicolas Zone (“San Nicolas”) within the past-producing Quebradillas mine.
Key highlights include:
• Hole IDP-SN-26-001 returned 473 g/t Ag.Eq over 3.60 m, including 740 g/t Ag.Eq over 1.65
m and 527 g/t Ag.Eq over 0.90 m.
• Hole IDP-SN-26-001, combined with previously drilled holes, confirmed the presence of a high-
grade block of mineralization extending at least 90 m above the last mined stopes at San
Nicolas along a minimum strike length of 45 m.
• Hole IDP-SN-26-003 returned 137 g/t Ag.Eq over 11.95 m, including 320 g/t Ag.Eq over
2.75 m and 507 g/t Ag.Eq over 0.90 m.
• Hole IDP-SN-26-004 returned 420 g/t Ag.Eq over 0.40 m.
• Hole IDP-SN-26-005 returned 275 g/t Ag.Eq over 1.05 m.
• Hole EDP-SN-26-001 returned 149 g/t Ag.Eq over 8.45 m, including 285 g/t Ag.Eq over
3.50 m.
• Hole EDP-SN-26-002 returned 183 g/t Ag.Eq over 3.20 m , including 299 g/t Ag.Eq over
1.35 m.
• Hole EDP-SN-26-003 returned 137 g/t Ag.Eq over 1.10 m and 131 g/t Ag.Eq over 1.30 m.
• Holes IDP-SN-26-003 to 005 and EDP-SN-26-001 to 003, combined with the holes drilled as
part of previous drilling programs conducted by the Company, have the potential to extend the
Indicated and Inferred Resources at depth by additional 70 m and 45 m, respectively.
Greg McKenzie, President and CEO , commented: “We are pleased with the exploration and infill
drilling results at San Nicolas. Hole IDP-SN-26-001 has confirmed the presence of a high-grade block
of mineralization extending 90 m above the last mined stopes, while holes IDP-SN-26-003 to 005 and
EDP-SN-26-001 to 003 have confirmed the extension of the zone more than 85 m at depth below the
last mined stopes. These drill results have the potential to contribute towards expanding the La Parrilla
Mineral Resource at the San Nicolas Zone which remains open at depth.”
San Nicolas Zone
The San Nicolas Zone is considered part of the Quebradillas mine, located approximately 400 m to
the southwest, and connected to Quebradillas by underground development utilizing shared services
from the mine. San Nicolas had five development levels established and mined by First Majestic Silver
Corp. (“First Majestic”) and a ventilation raise from surface down to a depth of 275 m. As a result of
the drilling conducted by Silver Storm, the high-grade silver mineralization at San Nicolas can
now be traced with continuity down to a depth of approximately 480 m below surface.
The San Nicolas Zone is comprised of subvertical quartz -carbonate vein and breccia mineralization
striking northwest over approximately 600 m. Sulphide replacement zones occur within the hanging
wall and footwall along the bedding within the sediments. The sulphide mineralization is comprised of
pyrite, galena, sphalerite, acanthite, and native silver. A second set of east -west trending sulph ide-
bearing quartz-carbonate veins crosscuts the principal northwest trend. Breccia pipes (chimneys) form
at the intersection of these two trends.

Hole IDP-SN-26-001 was drilled 50 m above the topmost mined 1921 EL stope and returned 473 g/t
Ag.Eq over 3.60 m , including 740 g/t Ag.Eq over 1.65 m and 527 g/t Ag.Eq over 0.90 m . The
composited weighted average grade of historical channel samples from the 1921 EL stope returned
215 g/t Ag.Eq over a strike length of 19 m and an average width of 1.49 m.
Hole IDP-SN-26-001 was drilled in proximity to other holes that had been drilled as part of the previous
drilling programs at San Nicolas and is located:
• 22 m above and southeast of hole Q-23-024 (686 g/t Ag.Eq over 9.39 m ) and 25 m below
and southeast of the historic hole ILP-SN-19-08 (475 g/t Ag.Eq over 7.50 m) drilled by First
Majestic (see the news release published by the Company on January 29, 2024)
• 30 m above and northwest of hole Q-24-054 (294 g/t Ag.Eq over 7.00 m ) and 32 m below
and northwest of hole Q-24-056 (616 g/t Ag.Eq over 1.02 m) (see the news release published
by the Company on January 6, 2025).
Collectively these holes, along with the historic hole SLP-SN-12-02 (248 g/t Ag.Eq over 2.15 m) drilled
by First Majestic, confirm the presence of a high-grade block of mineralization, extending at least
90 m above the last mined stopes in San Nicolas along a minimum strike length of 45 m . The
high-grade block was classified as part of the Indicated Resources in the National Instrument 43-101
– Standards of Disclosure for Mineral Projects (“ NI 43-101”) Technical Report entitled "Independent
Technical Report for the La Parrilla Silver Mine, Durango State, Mexico" with an effective date of March
24, 2025 (“Technical Report”).
Holes IDP-SN-26-003 to 005 and EDP -SN-26-001 to 003 targeted the southeast depth extension of
San Nicolas, where previous drilling programs produced the following results:
• Hole Q-23-013A (584 g/t Ag.Eq over 1.00 m within a broader interval of 276 g/t Ag.Eq
over 4.09 m) and hole Q-23-014 (225 g/t Ag.Eq over 1.90 m) (see the news release published
by the Company on January 29, 2024)
• Hole Q-24-063 (632 g/t Ag.Eq over 0.40 m and 450 g/t Ag.Eq over 0.50 m) (see the news
release published by the Company on January 6, 2025)
Highlights from holes IDP-SN-26-003 to 005 and EDP-SN-26-001 to 003 include:
• Hole IDP-SN-26-003 returned 137 g/t Ag.Eq over 11.95 m, including 320 g/t Ag.Eq over
2.75 m and 507 g/t Ag.Eq over 0.90 m
• Hole IDP-SN-26-004 returned 252 g/t Ag.Eq over 0.40 m and 420 g/t Ag.Eq over 0.40 m
• Hole IDP-SN-26-005 returned 275 g/t Ag.Eq over 1.05 m
• Hole EDP-SN-26-001 returned 149 g/t Ag.Eq over 8.45 m, including 285 g/t Ag.Eq over
3.50 m
• Hole EDP-SN-26-002 returned 183 g/t Ag.Eq over 3.20 m, including 299 g/t Ag.Eq over
1.35 m
• Hole EDP-SN-26-003 returned 137 g/t Ag.Eq over 1.10 m and 131 g/t Ag.Eq over 1.30 m
These six holes have extended the San Nicolas mineralization to ~85 m below the bottommost 1874
EL stope. The composited weighted average grade of historical channel samples from the 1874 EL
stope returned 279 g/t Ag.Eq over a strike length of 35 m and average width of 1.15 m. By using the
classification criteria established in the Technical Report, these holes have the potential to extend
the Indicated Resources by additional 70 m at depth over a minimum strike length of 65 m and
to extend the Inferred Resources by additional 45 m at depth.
Silver Storm has recently added a second underground drill rig to advance the current drilling program
more rapidly. A total of 44 holes have been drilled to date (~3,000 m).

(1) The individual grades of the metals that were used as inputs into the metal equivalent Ag.Eq g/t are provided
in Tables 1 & 2.
(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 g old, 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; channel samples were taken perpendicular across the width of mineralization
and are considered true widths (“TW”).
(4) Weighted average grades were calculated over the mineralized widths of each channel across the stope
(Table 2, Figure 2).
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 phot ographed, 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.
