Silver Storm Drills 516 g/t Ag.Eq Over 3 m Within Broader Interval of 302 g/t Ag.Eq Over 15 m in Norte-Sur and Extends High-Grade Zone 180 m at Depth

TORONTO--(BUSINESS WIRE)--Silver Storm Mining Ltd. (“Silver Storm” or the "Company") (TSX.V: SVRS | OTC: SVRSF | FSE: SVR), is pleased to announce drill results from its Phase 2 diamond drilling program at the Company’s 100% owned La Parrilla Silver Mine Complex, located in Durango Mexico. Results from the 5 holes (1,182 metres (“m”)) contained within this release are from the Norte-Sur Zone, within the Quebradillas mine.

An overview video on the La Parrilla Project is available at: www.youtube.com/watch?v=dybgKXcGrYo

Key highlights include:

Numerous high-grade intercepts were encountered within the Norte-Sur Zone up to 180 m beyond the last mined levels where the following channel samples and mining widths were observed (Figures 2 & 3):

• 1749 EL graded 358 g/t Ag.Eq¹ over a strike length of 51 m and an average width of 3.6 m
• 1737 EL graded 407 g/t Ag.Eq over a strike length of 28 m and an average width of 3.2 m; however, FM had only mined ~50% of this stope when the operation was placed on care & maintenance

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 Q-24-040 successfully returned 516 g/t Ag.Eq over 3.00 m, 406 g/t Ag.Eq over 0.50 m, and 592 g/t Ag.Eq over 1.00 m within a broader interval of 302 g/t Ag.Eq over 15.00 m.
• Hole Q-24-041 intersected 356 g/t Ag.Eq over 1.55 m at the previously interpreted northwestern boundary of the Norte-Sur Zone which highlights the potential for expansion of the zone along strike in this direction.
• Hole Q-24-042 returned 299 g/t Ag.Eq over 4.30 m including 914 g/t Ag.Eq over 0.50 m and 655 g/t Ag.Eq over 0.60 m. Prior to reaching the Norte-Sur target, this hole intersected 4.50 g/t Au over 1.00 m. Another gold-rich zone was also intersected further down the hole returning 4.56 g/t Au over 1.39 m.
• Hole Q-24-043 successfully intersected 287 g/t Ag.Eq over 6.60 m, including 523 g/t Ag.Eq over 1.58 m and 397 g/t Ag.Eq over 1.00 m and 491 g/t Ag.Eq over 0.55 m. These high-grade intersections, located approximately 180 m below the last mined area within the Norte-Sur Zone, demonstrate the potential for resource expansion at depth.

Greg McKenzie, President and CEO, commented: “Our Phase 1 & 2 high-grade drill results demonstrate the Norte-Sur Zone extends at least 180 metres below the previous mined stopes, with excellent lateral continuity, and remains open at depth. The distribution of high-grade drill holes in this area, combined with channel sample results taken within previously mined stopes, provide us with confidence in prioritizing this area for potential restart of mining activities.”

Norte-Sur Zone

The Norte-Sur Zone (NS) is a fault-vein hosted in the limestone and granodiorite stock with replacement bodies developed in the footwall and hanging wall. It strikes northwest and dips 71° to the northeast (315/71) over a known strike length of 125 m (Figure 1). The mineralization extends vertically for 565 m and its true width varies up to 5 m. The last two levels developed at depth on the Norte-Sur Zone returned the following composited weighted average grades from historical channel samples, which are representative of the mineralization mined from this area:

• 1749 EL graded 358 g/t Ag.Eq over a strike length of 51 m and an average width of 3.6 m
• 1737 EL graded 407 g/t Ag.Eq over a strike length of 28 m and an average width of 3.2 m; however, FM had only mined ~50% of this stope when the operation was placed on care & maintenance

Holes Q-24-040, Q-24-041, Q-24-042

Three infill holes were designed to demonstrate vertical continuity between holes Q-23-007 (324 g/t Ag.Eq over 8.72 m, including 436 g/t Ag.Eq over 4.46 m) and ILP-Q-18-50 (479 g/t Ag.Eq over 3.85 m including 564 g/t Ag.Eq over 2.90 m), as well as expand the current boundary of Indicated Resources ~100 m down-dip. The three holes are located approximately 135 m below the last mined level in Norte-Sur.

Hole Q-24-040 successfully returned 516 g/t Ag.Eq over 3.00 m, 406 g/t Ag.Eq over 0.50 m, and 592 g/t Ag.Eq over 1.00 m within a broader interval of 302 g/t Ag.Eq over 15.00 m (186.60 to 201.60 m) – Table 1; Figure 2.

Hole Q-24-041 intersected 356 g/t Ag.Eq over 1.55 m (207.90 to 209.45 m) at the previously interpreted northwestern boundary of the Norte-Sur Zone which highlights the potential for expansion of the zone along strike in this direction.

Hole Q-24-042 returned 299 g/t Ag.Eq over 4.30 m (207.00 to 211.30 m), including 914 g/t Ag.Eq over 0.50 m and 655 g/t Ag.Eq over 0.60 m. Prior to reaching the Norte-Sur target, this hole intersected 4.50 g/t Au over 1.00 m (167.05 to 168.05 m). Another gold-rich zone was also intersected further down the hole returning 4.56 g/t Au over 1.39 m (228.45 to 229.84 m).

Hole Q-24-043

Hole Q-24-043 was designed to test the Norte Sur Zone at depth, successfully intersecting 287 g/t Ag.Eq over 6.60 m (242.40 to 249.00 m), including 523 g/t Ag.Eq over 1.58 m and 397 g/t Ag.Eq over 1.00 m and 491 g/t Ag.Eq over 0.55 m. Although the widths appear to be narrowing at depth, the shallow angle of this hole to the zone (20-30 degrees) prevented it from obtaining an adequate cross-section of the mineralization. More importantly, these high-grade intersections, located approximately 180 m below the last mined area within the Norte-Sur Zone, demonstrate the depth extension of the mineralization which remains open at depth. The vertical continuity established by hole Q-24-043 should allow for expansion of Inferred Resources to depth. Q-24-043 is one of the deepest holes drilled to date within the Quebradillas mine (~600 m vertical depth from surface) exhibiting the potential to expand mineralization at depth within all zones in the mine.

(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. (2) Weighted average grades were calculated over the mineralized widths of each channel across the stope (Figures 1 & 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 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.
