Key highlights include:

Numerous high-grade intercepts were encountered within the Rosarios Mine underneath and in proximity to previous mined stopes. The current drill results, when combined with historical holes drilled by First Majestic (“FM”), are expected to have a positive impact on future Mineral Resources.

• Hole RO-24-028 returned 1,306 g/t Ag.Eq¹ over 1.60 m within a broader interval of 887 g/t Ag.Eq over 2.54 m. Hole RO-24-015 returned 1,791 g/t Ag.Eq over 0.35 m within a broader interval of 711 g/t Ag.Eq over 1.03 m and 1,170 g/t Ag.Eq over 0.50 m and 1,071 g/t Ag.Eq over 1.35 m within a broader interval of 598 g/t Ag.Eq over 3.91 m.

- These high-grade intercepts are located ~ 45 m to the west a previously mined stope

• Hole RO-24-032A returned 731 g/t Ag.Eq over 1.40 m and 510 g/t Ag.Eq over 0.50 m within a broader interval of 305 g/t Ag.Eq over 5.60 m.
• Hole RO-24-034 returned 350 g/t Ag.Eq over 1.06 m, 475 g/t Ag.Eq over 0.40 m and 617 g/t Ag.Eq over 0.42 m, 396 g/t Ag.Eq over 0.40 m and 592 g/t Ag.Eq over 0.40 m and 1,085 g/t Ag.Eq over 0.50 m.

- These high-grade intercepts are located ~ 35 m under the last stope mined in this area

• Hole RO-24-026 returned 421 g/t Ag.Eq over 1.13 m and 316 g/t Ag.Eq over 1.72 m within a broader interval of 276 g/t Ag.Eq over 5.46 m. Historical hole LBT-11-01 intersected 523 g/t Ag.Eq over 0.60 m and 670 g/t Ag.Eq over 1.30 m. Hole RO-24-014 returned 285 g/t Ag.Eq over 1.02 m and 431 g/t Ag.Eq over 0.69 m. Historical hole ILP-RO-18-60 returned 1,167 g/t Ag.Eq over 1.45 m within a broader interval of 434 g/t Ag.Eq over 6.25 m.

- This high-grade area extends approximately 148 m below the last stope mined in this area and 128 m below Indicated and Inferred Resources identified by SRK

Three exploration holes confirm the continuity of the San Carlos Zone, first discovered by FM in 2015 with hole ILP-14M-15-02 returning 361 g/t Ag.Eq over 1.40 m: hole RO-24-036 returned 722 g/t Ag.Eq over 0.66 m and 284 g/t Ag.Eq over 0.50 m. The mineralization from these holes is located 135 m south of the Rosarios Zone and approximately 335 m from surface.

Greg McKenzie, President and CEO, commented: “We are pleased with the high-grade results within Central Rosarios, now with six intercepts exceeding 1,000 g/t Ag.Eq. It is important to recognize this area was predicted to be blank. The results reported today extend the high-grade mineralization up to 128 m below the Indicated and Inferred Resources identified by SRK and we anticipate the drilling will have a positive impact on future Mineral Resources, both in terms of tonnage and grade.”

Rosarios Zone

The Rosarios Zone (RO) has historically been an important part of the La Parrilla Mine Complex, characterized by a sulphide-bearing quartz-carbonate vein hosted within a fault zone striking 290 degrees and dipping 64 degrees to the northeast over a known strike length of approximately 2 km. The mineralization extends vertically for 900 m and its true width varies up to 14 m. The vein sits roughly at the northern contact of a granodiorite stock and sediments. Stockwork zones are developed either at the footwall or hanging wall of the vein; vein splays and sulphide replacement zones are typically developed in the hanging wall. The Rosarios Zone remains open along strike and at depth. The zone has been subdivided into the Western, Central, and Eastern Rosarios. Phase 1 and historical drill results from the Rosarios Zone were previously reported in the Company’s news release dated May 27, 2024. The focus of the Phase 2 drill program has been on the Central Rosarios Zone.

Central Rosarios

Holes RO-24-024 to 034 targeted the Central Rosarios Zone with the intent of providing a sufficient drilling density to identify Indicated Resources, as well as further extending Inferred Resources at depth (Figures 1, 2).

Three areas of high-grade mineralization were identified in Central Rosarios (Table 1):

Hole RO-24-028 returned 1,306 g/t Ag.Eq over 1.60 m within a broader interval of 887 g/t Ag.Eq over 2.54 m (89.70 to 92.24 m), approximately 35 m below and to the east of hole RO-24-016 which returned 498 g/t Ag.Eq over 0.5 m and 338 g/t Ag.Eq over 0.5 m within a broader interval of 181 g/t Ag.Eq over 3.52 m (78.82 to 82.34 m) and 30 m above and to the west of hole RO-24-015 (reported May 27, 2024) which returned 1,791 g/t Ag.Eq over 0.35 m within a broader interval of 711 g/t Ag.Eq over 1.03 m (75.67 to 76.70 m) and 1,170 g/t Ag.Eq over 0.50 m and 1,071 g/t Ag.Eq over 1.35 m within a broader interval of 598 g/t Ag.Eq over 3.91 m (106.94 to 110.85 m).

• This high-grade zone is located approximately 45 m to the west of previously a mined stope

Hole RO-24-032A returned 731 g/t Ag.Eq over 1.40 m and 510 g/t Ag.Eq over 0.50 m within a broader interval of 305 g/t Ag.Eq over 5.60 m (174.90 to 180.50 m). Hole RO-24-034 returned 350 g/t Ag.Eq over 1.06 m, 475 g/t Ag.Eq over 0.40 m and 617 g/t Ag.Eq over 0.42 m within a broader interval of 234 g/t Ag.Eq over 4.24 m (205.06 to 209.30 m), 396 g/t Ag.Eq over 0.40 m and 592 g/t Ag.Eq over 0.40 m within broader interval of 232 g/t Ag.Eq over 2.00 m (212.42 to 214.42 m), and 1,085 g/t Ag.Eq over 0.50 m (224.23 to 224.73 m).

• This high-grade zone is located approximately 35 m beneath the last stope mined in this area

Hole RO-24-026 returned 421 g/t Ag.Eq over 1.13 m and 316 g/t Ag.Eq over 1.72 m within a broader interval of 276 g/t Ag.Eq over 5.46 m (201.34 to 206.80 m). Historical hole LBT-11-01, approximately 47 m to the east, intersected 523 g/t Ag.Eq over 0.60 m and 670 g/t Ag.Eq over 1.30 m within a broader interval of 268 g/t Ag.Eq over 5.90 m (286.70 to 292.60 m). Hole RO-24-014 (reported May 27, 2024) returned 285 g/t Ag.Eq over 1.02 m (132.15 to 133.17 m) and 431 g/t Ag.Eq over 0.69 m (139.88 to 140.57 m) and historical hole ILP-RO-18-60 returned 1,167 g/t Ag.Eq over 1.45 m within a broader interval of 434 g/t Ag.Eq over 6.25 m (131.45 to 137.70 m).

• This high-grade zone extends approximately 148 m below the last stope mined in this area and 128 m below Indicated and Inferred Resources identified by SRK.

San Carlos Zone

The San Carlos Zone (SC) was first discovered by FM through exploration drilling in 2015 with hole ILP-14M-15-02 returning 361 g/t Ag.Eq over 1.40 m (115.45-116.85 m) (Figure 3, Table 1). Three follow-up holes were recently drilled testing continuity of the SC zone, with hole RO-24-036 returning 722 g/t Ag.Eq over 0.66 m (112.43 to 113.09 m) and 284 g/t Ag.Eq over 0.50 m (136.46 to 136.96 m) and hole RO-24-035 returning 156 g/t Ag.Eq over 0.50 m (159.95 to 160.45 m). The zone intersections in hole RO-24-035 and 036 are respectively 54 m downdip and 65 m downdip and ENE along strike from ILP-14M-15-02. The zone in RO-24-036 is 55 m ENE along strike from RO-24-035. The intercepts from these three holes are located 135 m south of the Rosarios Zone and approximately 335 m from surface, mineralization is comprised of a sulphide-bearing quartz vein zone, striking 245-255 degrees and dipping 88 degrees NNW, hosted within intensely propylitic altered sediments. San Carlos may be a fault splay from the main Rosarios Zone to the WSW into the hanging wall.

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$22.50 /oz Ag, US$1,800 /oz Au, US$0.94 /lb Pb, and US$1.35 /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, respectively 140 g/t Ag.Eq and 125 g/t Ag.Eq and are based on 2017 costs adjusted by the inflation rate and include sustaining costs.

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.

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, including, but not limited to, there being no assurance that the Company’s current and future exploration programs will grow the Mineral Resource base or upgrade Mineral Resource confidence, the risk that the assumptions referred to above prove not to be valid or reliable, the risk that the Company is unable to achieve its goal of placing La Parrilla back into production; market conditions and volatility and global economic conditions including increased volatility and potentially negative capital raising conditions resulting from the continued or escalation of the COVID-19 pandemic, risk of delay and/or cessation in planned work or changes in the Company’s financial condition and development plans; risks associated with the interpretation of data (including in respect of third party mineralized material) regarding the geology, grade and continuity of mineral deposits, the uncertainty of the geology, grade and continuity of mineral deposits and the risk of unexpected variations in Mineral Resources, grade and/or recovery rates; risks related to gold, silver and other commodity price fluctuations; employee relations; relationships with and claims by local communities and indigenous populations; availability and increasing costs associated with mining inputs and labour, the speculative nature of mineral exploration and development, including the risks of obtaining necessary licenses and permits and the presence of laws and regulations that may impose restrictions on mining, including the Mexican mining reforms; risks relating to environmental regulation and liability; the possibility that results will not be consistent with the Company’s expectations.

Such forward-looking information represents managements 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.
