Silver Storm Demonstrates Resource Growth Potential at the C550 Zone, Expands the 2026 Drilling Campaign by 9,000 Metres
Toronto, Ontario, May 21, 2026: Silver Storm Mining Ltd. (“Silver Storm” or the "Company") (TSX.V: 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. Drill results in this release are from the C550 and C535 Zones within the past-producing Quebradillas mine.
Key highlights include:
C550 Zone
Hole IDP-QB-26-042 returned 160 g/t Ag.Eq(1,2) over 3.55 metres (“m”) (ETW(3) 2.5 m) and 165 g/t Ag.Eq over 1.90 m (ETW 1.2 m).
Hole EDP-QB-26-004 returned 1,226 g/t Ag.Eq over 0.30 m (ETW 0.2 m) and 144 g/t Ag.Eq over 2.50 m (ETW 2.0 m).
Hole IDP-QB-26-013 returned 167 g/t Ag.Eq over 1.80 m (ETW 1.0 m) and 622 g/t Ag.Eq over 0.70 m (ETW 0.4 m).
Hole IDP-QB-26-020 returned 195 g/t Ag.Eq over 1.66 m (ETW 1.7 m) and 331 g/t Ag.Eq over 2.95 m (ETW 2.9 m).
These drill results are consistent with historical channel sample results from the four mined levels within the C550 Zone. On average, the channel sample widths varied from 1.0 m to 2.4 m, while grades varied between 182 g/t to 309 g/t Ag.Eq.
The infill and exploration drill results at the C550 Zone demonstrated the potential to extend the Indicated Resources by 75 m along strike and 90 m at depth, while the Inferred Resources could potentially be extended by 50 m at depth.
C535 Zone
Hole IDP-QB-26-021 returned 441 g/t Ag.Eq over 21.72 m (ETW 3.8 m), including 771 g/t Ag.Eq over 9.27 m (ETW 1.6 m).
Hole IDP-QB-26-041 returned 513 g/t Ag.Eq over 2.00 m (ETW 1.3 m) 45 m down-dip from hole IDP-QB-26-021.
Greg McKenzie, President and CEO, commented: “We are pleased with the infill and exploration drill results at the C550 Zone that demonstrated the potential to grow the La Parrilla Mineral Resource. At the C535 Zone, drilling returned high-grade intercepts that support our plan to conduct further exploration work in the near term.
Given the success of the 2026 La Parrilla drill campaign to date, the initial 6,000 m campaign will be expanded with additional 9,000 m of drilling.”
