TORONTO, ON / ACCESS Newswire / August 6, 2026 / Silver Storm Mining Ltd. ("Silver Storm" or the "Company") (TSXV: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. Drillhole results in this release are from the Rosarios Zone within the past-producing Rosarios mine.

Key highlights include:

• Hole IDP-RO-26-004 returned 215 g/t Ag.Eq over 11.90 metres ("m") (ETW 11.9 m).

• Hole IDP-RO-26-007 returned 200 g/t Ag.Eq^(1,2) over 15.35 m (ETW⁽³⁾ 13.3 m).

• Hole IDP-RO-26-005 returned 297 g/t Ag.Eq over 7.30 m (ETW 7.2 m), 160 g/t Ag.Eq over 4.85 m (ETW 4.8 m), and 196 g/t Ag.Eq over 3.85 m (ETW 3.8 m).

• Hole IDP-RO-26-002 returned 239 g/t Ag.Eq over 5.90 m (ETW 5.7 m).

• Hole IDP-RO-26-008 returned 481 g/t Ag.Eq over 1.65 m (ETW 1.6 m) and 149 g/t Ag.Eq over 4.10 m (ETW 3.9 m).

• Hole IDP-RO-26-003 returned 442 g/t Ag.Eq over 1.00 m (ETW 0.9 m).

• The infill drill results from the Rosarios Zone highlighted the potential to extend the Indicated Resources by additional 100 m toward the surface along a strike length of 125 m.

Greg McKenzie, President and CEO, stated: "We are pleased to deliver yet another impressive set of drill results, this time demonstrating the potential to increase the La Parrilla Mineral Resource at the Rosarios Zone. We will continue our 15,000 m drilling program to grow the resource footprint while operations ramp up at La Parrilla."

Rosarios Zone

The Rosarios Zone has historically been an important part of La Parrilla and is characterized by a sulphide-bearing quartz-carbonate vein hosted within a fault zone striking west-northwest and dipping 64 degrees to the northeast over a known strike length of approximately 2 km. The mineralization at Rosarios extends vertically for 900 m, and its true width varies by up to 14 m. The Rosarios vein is located roughly at the northern contact of sediments and granodiorite stock. Stockwork zones are developed either in the footwall or hanging wall of the Rosarios vein, while vein splays and sulphide replacement zones are typically developed in the hanging wall. The Rosarios Zone remains open both along strike and at depth.

Table 1 summarizes the results from the 8 infill holes drilled at the Rosarios Zone targeting the oxide mineralization.

Highlights from the near-surface drilling conducted in the western portion of the Rosarios Zone include:

• Hole IDP-RO-26-007 returned 200 g/t Ag.Eq over 15.35 m (ETW 13.3 m) in oxide mineralization.

• Hole IDP-RO-26-004 returned 215 g/t Ag.Eq over 11.90 m (ETW 11.9 m) in oxide mineralization.

• Hole IDP-RO-26-005 returned 297 g/t Ag.Eq over 7.30 m (ETW 7.2 m) in sulphide mineralization, as well as 160 g/t Ag.Eq over 4.85 m (ETW 4.8 m) and 196 g/t Ag.Eq over 3.85 m (ETW 3.8 m) in oxide mineralization.

• Hole IDP-RO-26-002 returned 239 g/t Ag.Eq over 5.90 m (ETW 5.7 m) in oxide mineralization.

• Hole IDP-RO-26-008 returned 481 g/t Ag.Eq over 1.65 m (ETW 1.6 m) in oxide mineralization and 149 g/t Ag.Eq over 4.10 m (ETW 3.9 m) in oxide mineralization.

• Hole IDP-RO-26-003 returned 442 g/t Ag.Eq over 1.00 m (ETW 0.9 m) in oxide mineralization.

The infill drill results from the Rosarios Zone demonstrate the potential to extend the Indicated Resources by additional 100 m toward the surface along a strike length of 125 m.

Underground rehabilitation and development activities within the past-producing Rosarios mine are underway. All mineralized intersections reported in this release are proximal to existing infrastructure and development within the mine.

Silver Storm has two underground drill rigs and one surface drill rig in operation to advance the current drilling program. A total of 115 holes have been completed to date (~13,000 m).
