Blossom Gold Announces Rehabilitation of Decline #2 Underway at Rosebud

TORONTO, Aug. 25, 2026 (GLOBE NEWSWIRE) — Blossom Gold Inc. (“ Blossom ” or the “ Company ”) (TSX: BGAU) is pleased to announce that Portal #2 at its Rosebud Project in Pershing County, Nevada, is now open and rehabilitation work is underway. Blossom’s mining contractor, Small Mine Development LLC (“SMD”), has mobilized to site, completed earthworks to reestablish access to the portal opening and, following drilling and blasting of the concrete plug on August 24 th , has secured full access to Decline #2 and rehabilitation of the decline.

SMD’s work involves approximately 3,000 feet (915 meters) of rehabilitation planned for Decline #2. Rehabilitation work will include ground support, ventilation, and utility installation to restore safe underground access. Underground drill stations will be established concurrently as rehabilitation work allows to provide locations for infill drilling of the Rosebud open-pit resource in accordance with Blossom’s underground, infill drilling program. The underground, infill drilling program is designed to upgrade the classification of the open-pit resource and test the potential for higher-grade underground mineralization more efficiently than is possible from surface drilling under the five-acre constraint of the Company’s Notice of Intent. Underground drilling contractors have been identified and are being evaluated. The underground infill program will involve approximately 27,000ft (8,200 meters) of drilling and will commence in Q4 2026. Results from the program are intended to support an updated Mineral Resource Estimate targeted for the first quarter of 2027, in support of feasibility studies and permitting associated with Rosebud’s Plan of Operations with the Bureau of Land Management.

Graden Colby, Blossom’s COO, commented, “Blasting the concrete closure plug and gaining full access to Decline #2 after 25 years is a fundamental milestone in our continuing evaluation of Rosebud. We had more work to do than expected to reestablish access but now that rehabilitation is underway, we expect to get back on schedule. SMD’s scope of work includes rehabilitation, drill bay development and bulk sampling for continued metallurgical testing and heap leach optimization. Infill drilling will begin in Q4 and is critical to generating the data we need to meet our schedule for an updated open-pit mineral resource estimate in Q1 2027. Portal #2 provides access to the historic workings of the former Rosebud underground mine, which produced approximately one million tons of ore grading over 15gAu/t from 1997 through 2000. Blossom continues to evaluate the potential for higher grade underground resources, which will benefit directly from the rehabilitation of Decline #2 that is now underway.”
