Key highlights include:

Numerous high-grade intercepts were encountered within the Rosarios Mine underneath and in proximity to previous mined stopes. Collectively, the three high-grade zones identified within Central Rosarios during Phase 1 & 2 drilling span a strike length of 275 m down to a depth of ~600 m and remain open at depth (Figures 1 & 2).

• Hole RO-24-047 returned 584 g/t Ag.Eq¹ over 1.81 m within a broader interval of 338 g/t Ag.Eq over 4.23 m extending the high-grade zone outlined by holes RO-24-015 (1,791 g/t Ag.Eq over 0.35 m within a broader interval of 711 g/t Ag.Eq over 1.03 m), 016, & 028 (1,306 g/t Ag.Eq over 1.60 m within a broader interval of 887 g/t Ag.Eq over 2.54 m) down dip by ~50 m.
• Hole RO-24-041 returned 553 g/t Ag.Eq over 0.60 m and hole RO-24-042 returned 488 g/t Ag.Eq over 0.50 m further confirming the extent of the high-grade zone outlined by holes RO-24-014 (431 g/t Ag.Eq over 0.69 m) & 026 (421 g/t Ag.Eq over 1.13 m and 316 g/t Ag.Eq over 1.72 m) and historical holes ILP-RO-18-60 & LBT-11-01, which extend the high-grade zone approximately 148 m below the last stope mined in this area.
• Footwall sulphide zones ~60 m south of the Rosarios Zone were intersected in hole RO-24-038 which returned 444 g/t Ag.Eq over 0.50 m within a broader interval of 224 g/t Ag.Eq over 1.50 m from the RFW1 Zone, 179 g/t Ag.Eq over 0.55 m and 295 g/t Ag.Eq over 0.50 m from the RFW2 Zone, and 288 g/t Ag.Eq over 0.50 m within a broader interval of 187 g/t Ag.Eq over 1.45 m from the RFW3 Zone.

Greg McKenzie, President and CEO, commented: “We are really pleased with the drill results from Phase 1 & 2 within Central Rosarios. Three of the high-grade areas collectively reported today outline a terrific zone at depth with continuity over a strike length of 275 metres. Two of these areas were predicted to be blank within the existing resource model.

Following up on some individual historical holes, such as ILP-LBT-12-01 that returned 871 g/t Ag.Eq over 1.50 m within a broader interval of 531 g/t Ag.Eq over 6.05 m, a few drillholes were allowed to extend south of Rosarios which resulted in the discovery of four new footwall zones. A pattern of high-grade replacement sulphide zones is emerging within this area and future drilling will be planned to follow up on the potential of these footwall targets.”

The current drill results, when combined with historical holes drilled by First Majestic, are expected to have a positive impact on future Mineral Resources.

Rosarios Zone

The Rosarios Zone 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 & 2, as well as historical drill results, from the Rosarios Zone were previously reported in the Company’s news releases dated May 27, 2024 and August 15, 2024. The focus of the Phase 2 drill program within the Rosarios mine has been on the Central Rosarios Zone.

Central Rosarios

Holes RO-24-041 to 047 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). Infill drilling was conducted in two of the three areas of high-grade mineralization which were identified in Central Rosarios and previously reported in the Company’s news release dated August 15, 2024 (Table 1):

Hole RO-24-047 returned 584 g/t Ag.Eq over 1.81 m within a broader interval of 338 g/t Ag.Eq over 4.23 m (167.24 to 171.47 m), approximately 50 m below 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 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.

Holes RO-24-047 and RO-24-015 along with hole RO-24-028 (reported August 15, 2024) which 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 and 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 outline a high-grade zone within Rosarios extending 115 m vertically which is open at depth..

• This high-grade zone is located approximately 45 m to the west of previously a mined stope, within an area predicted to be blank by the existing resource model

Hole RO-24-041 which returned 553 g/t Ag.Eq over 0.60 m (76.40 to 77.00 m) and hole RO-24-042 which returned 488 g/t Ag.Eq over 0.50 m (57.30 to 57.80 m) intersected the second high-grade zone which was demarcated by hole RO-24-026 (reported August 15, 2024) which 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 and historical hole LBT-11-01 which 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. Hole RO-24-014 (reported May 27, 2024) which returned 285 g/t Ag.Eq over 1.02 m and 431 g/t Ag.Eq over 0.69 m and historical hole ILP-RO-18-60 which 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 are also within this high-grade zone.

• 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.

As previously reported on August 15, the third high-grade zone is demarcated by hole RO-24-032A which 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, and hole RO-24-034 which 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, 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, and 1,085 g/t Ag.Eq over 0.50 m.

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

Collectively, the 3 high-grade zones identified within Central Rosarios span a strike length of 275 m down to a depth of ~600 m and remain open at depth. The current drill results, when combined with historical holes drilled by FM, are expected to have a positive impact on future Mineral Resources.

Rosarios Footwall Zones

Holes RO-24-038 & 039 were drilled to target several zones of replacement sulphide mineralization (RFW1-RFW4) in the footwall of the Rosarios Zone which were identified by FM through exploration drilling in 2012 with historical hole ILP-LBT-12-01 returning 871 g/t Ag.Eq over 1.50 m within a broader interval of 531 g/t Ag.Eq over 6.05 m (319.10 to 325.15 m) (RFW1), 401 g/t Ag.Eq over 0.60 m within a broader interval of 259 g/t Ag.Eq over 1.80 m (358.70 to 360.50 m) (RFW2), 538 g/t Ag.Eq over 1.45 m (374.05 to 375.50 m)(RFW3), and 161 g/t Ag.Eq over 1.05 m (379.00 to 380.05 m)(RFW4)(Figure 3). Hole RO-24-038 returned 444 g/t Ag.Eq over 0.50 m within a broader interval of 224 g/t Ag.Eq over 1.50 m (64.50 to 66.00 m) from the RFW1 Zone, 179 g/t Ag.Eq over 0.55 m (102.65 to 103.20 m) and 295 g/t Ag.Eq over 0.50 m (103.70 to 104.20 m) from the RFW2 Zone, and 288 g/t Ag.Eq over 0.50 m within a broader interval of 187 g/t Ag.Eq over 1.45 m (114.80 to 116.25 m) from the RFW3 Zone. The sulphide replacement zone intersections in hole RO-24-38 are 19 m, 25 m, 27 m, and 29 m SW down dip beneath the respective zone intersections from hole ILP-LBT-12-01. Hole RO-24-039 returned 153 g/t Ag.Eq over 1.00 m (121.00 to 122.00 m) from the RFW2 Zone which is 55 m directly down dip beneath RFW2 in RO-24-038. The intercepts from these three holes are located ~60 m south of the Rosarios Zone and approximately 315 m from surface.

1. 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 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.
