BLOSSOM GOLD INTERCEPTS 106.8M AT 0.42GAU/T AND 44.8M AT 1.22GAU/T, AND EXTENDS NEAR-SURFACE MINERALIZATION AT ITS ROSEBUD OPEN-PIT HEAP-LEACH PROJECT

Blossom Gold Inc. has released further drill results from its continuing 2026 exploration program at the Rosebud open-pit heap-leach project in Pershing county, Nevada. This release builds on exploration results reported on June 30, 2026, and Aug. 12, 2026, and highlights continued expansion and infill success across the South, East and Northwest zones.

Highlights:

• South zone: Thick gold mineralization continues to surround the historic south mined zones and extend updip along the South Ridge fault zone. BG26-031 intersected 44.8 metres at 1.22 grams per tonne gold from 149.8 m, including 3.2 m at 5.06 g/t Au from 181.8 m.
• Near-surface oxide: RC26-009 intersected 60.1 m at 0.33 g/t Au from surface, including 19.6 m at 0.68 g/t Au from 40.5 m, and RC26-010 intersected 14.6 m at 0.24 g/t Au in the oxidized domain of the South zone.
• East zone: BG26-042 intersected 106.8 m at 0.42 g/t Au from 74.8 m, including 24.2 m at 0.72 g/t Au from 156.0 m. This supports a broad halo of gold mineralization around the historic mine workings.
• Maiden Northwest zone hole: BG26-033 intersected 18.5 m at 0.20 g/t Au from 38.9 m, starting at the upper bedrock contact. This may be part of a shallow zone of mineralization extending across the north part of the deposit.
• Program update: Four rigs are operating, with 11,585 m (38,000 feet) remaining in the 2026 surface program. The 8,230-metre (27,000-foot) underground infill program is expected to begin in Q4 2026, and an updated mineral resource estimate is expected in Q1 2027.

"The Blossom exploration program is picking up the pace, with 19,911 m of drilling completed so far this year. Our third batch of results continues to demonstrate the scale of the mineralized system at Rosebud, both around the historic workings and in the areas the underground operation left behind," said Rick Winters, chief executive officer of Blossom Gold. "In the South zone, BG26-031 returned 44.8 m at 1.22 g/t Au, including 3.2 m at 5.06 g/t Au, confirming thick gold mineralization around the historic south mined zones. Closer to surface, our reverse circulation drilling delivered as well, with RC26-009 intersecting 60.1 m at 0.33 g/t Au from surface in oxidized material. That is the kind of near-surface mineralization our open-pit, heap-leach vision is built on. In the East zone, BG26-042 intersected 106.8 m at 0.42 g/t Au, further defining the broad halo of mineralization around the old mine. Our first hole in the Northwest zone also found gold mineralization starting at the upper bedrock contact, which points to a potential shallow zone across the north part of the deposit.

"We have four rigs turning 24/7, with 11,585 m of surface drilling remaining in the 2026 program. Rehabilitation of the underground portal is on track to establish drill bays and begin the 8,230-metre underground infill program in the fourth quarter. Together, these programs will inform the updated mineral resource estimate we expect to deliver in the first quarter of 2027," added Mr. Winters.

Technical drilling for permitting and design work is now 100 per cent complete, with expansion resource drilling the focus of the continuing program. Three core drill rigs and one RC (reverse circulation) rig remain devoted to drilling aimed at expanding and upgrading the existing inferred open-pit resource of 70.8 million tons at 0.018 ounce per ton Au (0.62 g/t Au) and 0.189 ounce per ton silver (6.49 g/t Ag) for 1.28 million ounces of gold and 13.4 million ounces of silver (see About Blossom Gold Inc. section below for more information).

In the South zone, results from diamond drill holes BG26-031 and BG26-041 and RC drill holes RC26-009 and BG26-010, combined with previously reported South zone drill holes, confirm that significant thicknesses of gold mineralization surround the historic south mined zones and continue updip along the South Ridge fault zone, with gold grade extending to or near the top of bedrock. The oxidized domain extends to depths ranging from 20 to 75 metres below the surface.

In the East zone, results from diamond drill holes BG26-039 and BG26-042, together with previously reported East zone drill holes, support the presence of a broad halo of gold mineralization surrounding historic mine workings and extending southward and westward along strike toward the South zone. Gold mineralization intercepted by these two drill holes is in the non-oxidized domain.

Diamond drill hole BG26-033 targeted the Northwest zone and indicates there is a zone of gold mineralization starting at the upper bedrock contact. These results are similar to previously reported results from Site T in the Northeast zone and may represent a shallow zone of mineralization extending across the northern part of the deposit. Additional recent drilling from Site M of hydrothermally altered and mineralized rocks suggests this zone may extend to the northwest of BG26-033. Assay results for drill holes from Site M are pending.

"Drilling of the updip South Ridge fault zone targets is showing two zones of gold mineralization each hosted by dacite flows and breccia," stated Dr. John DeDecker, vice-president, exploration, of Blossom. "The upper zone is in the oxidized domain and is near surface, and the lower zone is higher grade, in the non-oxidized domain, and occurs at depth surrounding the historic mine workings. The presence of elevated gold grades in dacite is consistent with the interpretation by the former mine geologists that coherent volcanic rocks are more susceptible to fracturing and vein formation than strongly clay- and chlorite-altered fine-grained tuffaceous rocks are."

As previously noted, drill hole assay results are reported by zone over the approximately two-kilometre-by-1.6-kilometre open-pit target; the Northwest, Northeast, Southwest, South and East zones. In the East and South zones, the target is an updip extension of South Ridge fault zone (SRFZ) mineralization above the previously mined orebodies in areas of low drill density owing to the historic focus on high-grade underground mineralization. The Northeast and Northwest zones are in the Rosebud shear zone with low, historic drill density. Expansion drilling in these zones target the potential to add resource and push the resource pit shell to the north. The Southwest zone is also in the Rosebud shear zone domain and targets areas of low drill density to potentially expand the open-pit resource to the property boundary in the southwest of the Rosebud claims.

Drill hole inclination is taken into account to determine the true thickness of mineralized intervals from surface. All intervals Blossom reports will be true thicknesses unless otherwise noted. Only gold values are reported. In situ, the silver to gold ratio at Rosebud is 10:1 based on the National Instrument 43-101 technical report as well as historic production, adjusted for recoveries. However, Blossom will report gold only as opposed to gold equivalent results until such time the company has better information on forecast silver recoveries from the continuing metallurgical testing.

Blossom Gold continues to advance the 2026 Rosebud exploration program, which includes continued surface drilling with four drill rigs with a priority on resource expansion and infill holes going forward, though technical drilling will also be scheduled as needed in support of the project's plan of operations, environmental impact statement and feasibility study. To date, the company has drilled 19,911 metres of the planned 31,496-metre surface drilling campaign.

About Blossom Gold Inc.

Blossom is a Canadian-based precious metals exploration and development company that recently began trading on the Toronto Stock Exchange 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 ounce per ton (6.8 g/t Au), when gold prices ranged from $250 (U.S.) to $350 (U.S.) per ounce, 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 70,755,000 tons grading 0.62 g/t Au (0.018 ounce per ton gold) and 6.49 g/t Ag (0.189 ounce per ton gold) 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 $2,500 (U.S.) and $35 (U.S.) per ounce, respectively. The deposit is open in all directions.
