SILVER STORM COMMENCES REHABILITATION ACTIVITIES AT LA PARRILLA

Silver Storm Mining Ltd. has commenced rehabilitation activities at its 100-per-cent-owned La Parrilla silver mine complex in Durango state, Mexico.

Highlights:

• Processing plant rehabilitation program has commenced;
• Engineering contractor engaged and mobilized: Dynamic Engineering Services Ltd. was awarded the contract for rehabilitation of the La Parrilla processing plant; estimated completion time is seven to nine months;
• Sulphide circuit will be expanded to 1,250 tonnes per day, representing a 25-per-cent increase;
• Long-lead items ordered for processing plant, including flotation cells;
• Underground rehabilitation work under way: initial activities include drift cleaning, scaling, ventilation upgrades and recommissioning of underground services;
• Strategic restart plan: SRK Consulting (Canada) Inc. has been engaged to review the company's restart plan for La Parrilla.

"The commencement of rehabilitation activities and the ordering of long-lead items at La Parrilla marks an important milestone for Silver Storm," stated Greg McKenzie, president and chief executive officer. "With the existing infrastructure in place and recent financings completed, we are taking decisive steps in respect of the company's objective of bringing the historic La Parrilla silver mine complex back into production and creating value for our shareholders and the communities of Durango. Rehabilitation and preparation activities will take seven to nine months, and, subject to further technical evaluations, we could target the potential restart of operations as early as the second quarter of 2026."

Plant rehabilitation to be completed by Dynamic Engineering, expansion of sulphide circuit

The company is pleased to announce that Dynamic Engineering has been engaged to complete the rehabilitation of the La Parrilla processing plant.

As part of the rehabilitation activities, the nameplate capacity of the sulphide circuit of the processing plant will be expanded to 1,250 tonnes per day. A larger-capacity sulphide circuit will better align with the mineralization profile of La Parrilla, which is characterized by a large growth in sulphide material as disclosed in the most recent technical report for La Parilla filed by the company in March, 2025.

Dynamic Engineering mobilized its team to site at La Parrilla on Sept. 3, 2025, to commence its work and has made significant progress. Activities include rehabilitating the kitchen/mess hall, living quarters and office areas, replacing the roofs on several buildings, as well as purchasing tools and equipment for the rehabilitation efforts.

Rehabilitation of the processing plant is expected to take approximately seven to nine months to complete. Activities will comprise the maintenance, rehabilitation and installation of the new equipment required for any potential resumption of mineral processing activities at La Parrilla.

In July, 2025, the company placed an order for eight new 1,000-cubic-foot rougher and scavenger cells for the flotation circuit, which meet the requirements for the expanded feed rate. A new cyclone has also been ordered to increase the capacity of the grinding circuit. Manufacturing of these systems is well under way. Delivery of the flotation cells and cyclone is expected by December, 2025.

The crushing and milling circuit will have the primary jaw crusher replaced, the ball mills relined, motor systems serviced, and all feed lines, conveyors, screens and cyclones serviced and repaired. The building housing for the secondary crushing system will be reinforced. As part of the expansion of the sulphide circuit, one of the site's three ball mills will be redirected from the oxide circuit to process feed exclusively to the sulphide circuit.

The oxide leach and tailings plant will also be partially rehabilitated, including the repair of five leach tanks in order, and all related mechanical parts serviced and repaired. All pumps and valves will be removed, serviced, cleaned, reinstalled and repaired if required. The tailings systems will be inspected, cleaned and serviced.

Following the mechanical completion of rehabilitation activities of the processing plant, Dynamic Engineering will lead, manage and supervise all commissioning activities through the completion of wet commissioning.

SRK Canada review

The company's plans to restart La Parilla are largely based on internal data and reports in conjunction with management's knowledge of the property and the existing estimate of mineral resources on the property. There is no preliminary economic assessment, prefeasibility study or feasibility study of mineral reserves demonstrating economic and technical viability for the project, resulting in increased uncertainty and higher risks of economic and technical failure than would be the case if such studies were completed.

SRK Consulting (Canada) has been engaged to review all components of the company's plans to restart La Parrilla, including geomechanical, ventilation, water management, underground mine design, development schedules and mineral processing considerations.
