Written By Silver Storm Mining Inc.

Toronto, Ontario, April 21, 2026: 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.”
