Blossom Gold reopens Portal #2 at Rosebud

TORONTO, July 16, 2026 (GLOBE NEWSWIRE) -- Blossom Gold Inc. (“ Blossom ” or the “ Company ”) (TSX: BGAU) is pleased to announce that the reopening of Portal #2 at its Rosebud Project in Pershing County, Nevada, is underway. Blossom’s mining contractor, Small Mine Development LLC (“SMD”), began mobilizing on schedule July 7 and is now executing earthworks to reestablish access to the portal opening. It is anticipated that earthworks will be complete and Portal #2 opened the week of July 20. Rehabilitation will be conducted to allow safe access to drill and blast the concrete plug established during closure and reclamation of the portal. Following removal of the plug, SMD will have full access to Decline #2 and will begin the rehabilitation required to establish drill bays for underground, infill drilling of the Rosebud open-pit resource, planned to commence in the fourth quarter of 2026.

"Opening the underground has been a fundamental milestone in Blossom’s plans for Rosebud, allowing us the do the resource drilling we would not have been able to achieve from surface drilling under the five acre constraint of our Notice of Intent (“NOI”)." said Rick Winters, Blossom's CEO. "This work is authorized under a modification to the Federal NOI received in March as well as a new State of Nevada temporary water pollution control permit (“WPCP”), demonstrating the ability of Blossom’s permitting team and quality of our State and Federal regulators in understanding, assessing and approving our plans for the underground at Rosebud. We will continue permitting to allow us to make best use of our existing underground infrastructure and resources.”

Graden Colby, Blossom’s COO commented, “Small Mine Development is one of the best underground, mining contractors in the business for what we need at Rosebud. We look forward to working with SMD to complete the planned rehabilitation of Decline #2. Their work will also include drill bay development. We expect SMD will conduct bulk sampling for continued metallurgical testing and heap leach optimization. We continue to evaluate our higher-grade underground resources. SMD’s involvement enhances our execution planning and tightens our costing for development and bulk sampling. Of course, the most important near-term result is providing critical access by Q4 to test open-pit resource expansion and infill target potential more effectively than surface drilling alone and keep us on schedule for an updated Mineral Resource Estimate in the first quarter of 2027 to support a feasibility study and continued permitting for operations."

Portal #2 provides access to the historic workings of the former Rosebud underground mine, which operated from 1997 through 2000. Approximately 3,000 feet (915 meters) of rehabilitation in Decline #2 is planned for completion in late October. Concurrent with and following rehabilitation, drill bays will be established in accordance with the underground, infill drilling program currently under design to upgrade the open-pit resource. Underground drillers have been identified and are being assessed for the underground drilling contract. Blossom continues to evaluate the potential for higher grade underground resources, which will benefit directly from the work rehabilitation of Decline #2 makes possible.

About Blossom Gold Inc.

Blossom is a Canadian-based precious metals exploration and development company that recently began trading on the TSX under the symbol BGAU. Blossom acquired the Rosebud Project in connection with the TSX-listing and will be focused on the exploration and development of the project. The Rosebud Project includes the former Rosebud Mine, where mining was conducted from 1997 through 2000 by the Rosebud Mining Company, a Newmont-Hecla joint venture, using underground mining methods where the mine operated at a cut-off grade of approximately 0.2 opt Au (6.8 g/t Au), when gold prices ranged from US$250 to US$350/oz; with mined material truck-hauled approximately 120 miles to an existing Newmont oxide mill for processing.

The current vision for the Rosebud Project is to evaluate the remaining higher-grade mineralization and the surrounding larger volume of lower grade mineralization as a potential open pit mining operation with on-site, heap-leach processing and recovery of gold and silver. The Rosebud Project currently hosts an Inferred Mineral Resource of 70.755 million tons grading 0.62gAu/t (0.018opt Au) and 6.49gAg/t (0.189opt Ag) for 1.28 million ounces of gold and 13.4 million ounces of silver. The mineral resource estimate was open pit constrained using long term gold and silver prices of US$2,500 and US$35 per ounce respectively. The deposit is open in all directions.
