Blossom Gold Announces a Gold Discovery on the Kamma Claims

TORONTO, Oct. 06, 2026 (GLOBE NEWSWIRE) -- Blossom Gold Inc. (formerly, 1290448 B.C. Ltd.) (“Blossom” or the “Company”) (TSX: BGAU) is pleased to announce initial precious metals mineralization on its 100%-owned Kamma Claims, located west of the Company's Rosebud Open-Pit, Heap-Leach Project ("Rosebud" or the "Project") in Pershing County, Nevada. The discovery comes from the Company's first phase, reverse circulation ("RC") drilling program at Kamma, which commenced on August 31, 2026.

Highlights

• Hole KM26-003 intersected 7.6 meters grading 0.16 gAu/t from 38.1 meters or 0.005opt gold from 125 feet. KM26-003 represents a discovery of gold mineralization under shallow alluvium along a pronounced magnetic anomaly that is coincident with a range-bounding fault in a similar structural setting to the mineralization at the Hycroft Mine approximately 3 miles to the north.
  
• Targeting model validated: mineralization is associated with structures interpreted from aeromagnetic anomalies as conduits for mineralizing hydrothermal fluids, consistent with the Company's geological model.
  
• Favourable geological setting: Kamma occupies a graben setting similar to the Rosebud Claim Block and is positioned stratigraphically between the Hycroft Mine and Rosebud.
  
• Program status: The first phase RC program of seven scout holes totaling 10,000 feet (3,050 meters) has been completed. The primary objectives were to characterize alluvial depth, lithology, presence of hydrothermal alteration, and the potential for gold mineralization under alluvial cover on the Kamma claim block. All of these objectives were met in the process of making the Kamma discovery. Going forward, geochemical and lithological analyses of all drill holes will be used to vector towards potential higher-grade feeder structures with a core drilling program. Additional surface-based geochemical and geophysical work is being considered to complement RC drillhole-based geochemical vectoring.
  

“It does not get any better than this. You get some good ground in a good setting. You appreciate why plenty of serious folks didn’t focus on it. You turn it over to smart folks with good ideas who put boots on the ground and apply science. Lady Luck smiles. And there it is, gold mineralization!” said Rick Winters, Chief Executive Officer of Blossom. “This is an outstanding first phase result and we will now step back, get all the data we can out of our initial drilling and develop follow-up plans. Kamma has a solid budget through 2027 to advance this discovery and provides a second avenue for value creation while we continue to advance Rosebud to feasibility.”

The first phase Kamma RC program began in late August 2026 following approval of a Bureau of Land Management Notice of Intent in June 2026. The program was planned to test targets on the Kamma Claims, west of Rosebud and south of the Hycroft mine.

“The results confirm the aeromagnetic feature we targeted with KM26-003 representing a zone of hydrothermal alteration associated with gold mineralization along a mapped range-bounding fault parallel to those that host gold-silver mineralization the at Hycroft Mine, approximately 3 miles north,” added Dr. John DeDecker, Vice President, Exploration. “The style of alteration and mineralization we are seeing is encouraging and very reminiscent of what we see at Rosebud. We will conduct further geochemical analyses to vector toward higher-grade feeder structures in follow-up core drilling. It is particularly encouraging that the alluvial cover in many spots is relatively thin and that the gold intercepted by KM26-003 occurs at a depth of 38 meters.”

The Kamma Claims are situated in a graben setting similar to the Rosebud Claim Block and, although the area has a history of significant placer gold production, it had seen limited modern exploration prior to Blossom's program. Mapping completed ahead of drilling identified Badger Formation conglomerate rocks, placing the Kamma Claims stratigraphically between the Hycroft Mine and Rosebud. The Company's work indicates the claims host potential primary structures (Figure 1) that could provide mineralization pathways like those at the adjacent Hycroft Mine, including the Vortex silver discovery. The best zone of gold mineralization in KM26-003 is hosted in plagioclase-porphyritic dacite immediately below the alluvial contact at a down-hole depth of 25 meters and is associated with intense hydrothermal alteration and disseminated sulfide mineralization. Several additional intervals of weaker hydrothermal alteration and gold mineralization occur throughout KM26-003 suggesting proximity to hydrothermal fluid conduits (Figure 2).

The first phase RC drilling program has provided a good understanding of the depth to bedrock and bedrock lithologies across the claim block. Further geochemical analyses of all drill holes will be used to develop hydrothermal alteration and gold-pathfinder element models to assist with vectoring towards the core of this newly discovered gold-bearing hydrothermal system. The Company will integrate these results with the geophysical and geological datasets to design follow-up drilling, including step-out holes along strike and deeper holes to test the interpreted feeder structures. The Kamma program is funded within Blossom's existing 24-month budget, and results will guide 2027 drilling decisions. Exploration at Kamma is being advanced in parallel with the Company’s ongoing work at Rosebud.

A variety of magnetic anomalies were drilled to characterize depth of alluvial cover, lithology, hydrothermal alteration, and presence of mineralization. KM26-003 is associated with a pronounced magnetic low trending NNE for approximately 1,000 meters on the property, that is associated with a range-bounding fault that is parallel to mineralized faults at the Hycroft Mine approximately 3.5 miles to the north.

Several gold anomalies associated with hydrothermal alteration of the host dacite were intercepted throughout the hole, with the strongest anomaly occurring immediately below the alluvial cover-bedrock contact at a depth of only 80 feet (~25 meters). The presence of these anomalies suggests that the range-bounding fault hosts a gold-bearing hydrothermal system in a similar structural setting to Hycroft Mine 3.5 miles to the north.
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 gAu/t), 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.
