Blossom Gold Reports Initial Metallurgical Results and Engagement of Metallurgical Advisor for the Rosebud Open-Pit, Heap-Leach Project

TORONTO, Aug. 27, 2026 (GLOBE NEWSWIRE) -- Blossom Gold Inc. (formerly, 1290448 B.C. Ltd.) (“ Blossom ” or the “ Company ”) (TSX: BGAU) is pleased to announce initial bottle roll test results for multiple host rock types and alteration styles from both oxidized and fresh rock at the Rosebud Open-Pit Heap-Leach Project ("Rosebud" or the "Project") in Pershing County, Nevada. The results represent the beginning of a metallurgical test program to define the recovery characteristics of the major host rocks in the Rosebud deposit for the purpose of mine planning and feasibility studies. Kappes, Cassiday and Associates of Reno (“KCA”) is conducting the test work program.

Blossom is also very pleased to announce the engagement of Jim Wickens as metallurgical advisor for the Rosebud Project. Mr. Wickens is well known as an operating metallurgist with over 40 years of experience, much of that on projects in Nevada with Placer Dome, Barrick, and Augusta Gold. Mr. Wickens will be intimately involved in the development and review of metallurgical programs underway and planned with KCA for upcoming feasibility studies.

Blossom provided 50-foot (15.2m) intervals of PQ core to KCA’s Reno facilities. The intervals are composited and crushed to produce material for bottle roll leach tests on different crush sizes, followed by loading material into columns for further testing to establish a leach curve for material types and sizes. Intervals were selected to provide information on rock type, alteration style, and grade from near cutoff of 0.17gAu/t to 1gAu/t.

The initial bottle roll leach results are from five intervals in three metallurgical drill holes, BG26-002, BG26-007 and BG26-008. Further results are pending for intervals from three additional holes, BG26-004, BG26-005, BG26-006 as well as another metallurgical interval from BG26-008. Th
