Blossom Gold Announces Selection of Kappes, Cassiday and Associates as Lead for Rosebud’s Feasibility, the Rosebud Technical Team and Provides an Update on Permitting Activities Supporting a 2029 Start of Construction

TORONTO, Oct. 21, 2026 (GLOBE NEWSWIRE) — Blossom Gold Inc. (“Blossom Gold” or the “Company”) (TSX: BGAU) is pleased to announce the appointment of Kappes, Cassiday & Associates (“KCA”) as lead consultant for the Feasibility Study at its Rosebud Open-Pit Project (“Rosebud” or the “Project”) in Pershing County, Nevada. The Feasibility Study is expected to commence in the second quarter of 2027, following the delivery of an updated Mineral Resource Estimate (“MRE”) at the end of the first quarter of 2027. The Company is also pleased to announce progress with permitting activities required for the Project’s Environmental Impact Statement to maintain Blossom Gold’s schedule to advance Rosebud to construction by 2029.

Highlights

• KCA appointed lead Feasibility Study consultant: Reno-based KCA brings more than 50 years of heap leach, metallurgical, engineering and construction experience and is already familiar with Rosebud through its ongoing metallurgical test work on Rosebud metallurgical samples. KCA’s track record includes several major design through construction contacts, including for Agnico Eagle (engineering, procurement and construction management (“EPCM”) the contract for Pinos Altos and EPCM contract for La India), Gammon Lake Resources (EPCM contract for Ocampo) and Pan American Silver (EPCM contract for Dolores), to name a few.
• Full technical team in place for permitting and feasibility: KCA will coordinate feasibility work alongside Northern Lights Mining (resource estimation and mine design), GMining Services (mine geotechnical evaluation and studies), and NewFields MDTS (processing facilities geotechnical evaluation and design). Permitting is coordinated by principal environmental consultant Westland Resources (Federal and State coordination, biological, cultural, tribal engagement) and supported by SRK Consulting (hydrological and geochemical evaluation, studies and monitoring)
• Project Schedule aligned to allow commencement of construction in 2029 with first-production in late-2030, early-2031.

“We chose KCA to lead the Rosebud Feasibility Study because of KCA’s clear enthusiasm to be the lead for Rosebud’s feasibility and, most importantly, KCA does not build facilities that don’t work,” said Graden Colby, Chief Operating Officer of Blossom Gold. “KCA has a track record of taking feasibility studies through to engineering, procurement and construction, as it did at Pinos Altos and La India for Agnico Eagle and at Ocampo for Gammon Lake. Like Agnico and Gammon, that is exactly the standard we want for Rosebud, an owner-operator approach to feasibility with EPCM execution that leads to successful mines. KCA is familiar and works well with our other technical consultants and we look forward to the effort.”

On Track for Updated MRE in Q1:27 and Initiation of Feasibility/EIS in Q2:27

Drilling continues at Rosebud, 26,555m drilled since April with three core and one RC rig conducting expansion and infill drilling from surface. Rehabilitation of decline #2 is on schedule after Small Mine Development LLC (SMD) successfully worked through the one major fault in both declines, a splay off the South Ridge Fault. Timberline Drilling Inc. of Elko, Nevada has been selected as the underground drilling contractor for Rosebud. Drilling is expected to begin in December following establishment of drill stations. The remaining drill program to support the MRE involves an additional 11,585m of surface and 8,232m of underground drilling through Q1:27, for an expected total of over 46,000m of new NI 43-101 information for the updated resource estimate.

While feasibility will formally kick-off in Q2:27 there is and has been preliminary engineering done in support of the overall permitting process, both the Federal Environmental Impact Statement (EIS) and State of Nevada process. Blossom and our consultants have already identified expected water and power requirements, provided planning profiles for ore and waste, established facility layouts and infrastructure corridors. Geotechnical, geochemical and hydrology drilling for the expected open-pit has largely been completed. This work and related studies will feed directly into the feasibility study.

Permitting efforts are on schedule with critical path elements met to date. Annual, required raptor surveys were completed. Rosebud’s initial, humidity cell tests (HCT), considered a long lead element of waste characterization, are underway. Pre-EIS meetings have been held with regulators and interested parties. The Project Area for permitting has been defined and presented to Federal and State regulators. Baseline requirements have been determined and documented. Biological surveys began in September with archeology/culture surveys beginning in October. Blossom’s Tribal, community and government engagement efforts have begun.

Metallurgical testing continues with material going through Rosebud’s assessment process at KCA’s lab, including bottle rolls, columns and additional testing to assess carbon-in-leach, carbon-in-pulp and flotation processing. Column results will begin being reported later in Q4.

“I wish every shareholder could visit site and see what has transpired since we began work in April this year!” said Rick Winters, Chief Executive Officer of Blossom Gold. “There were only two years in Rosebud’s history when there was over 25,000m of drilling, in 1990 under LAC Minerals and 1998 under the Hecla/Newmont JV. With an expected 46,000m of Blossom drilling we are very confident we can meaningfully expand and upgrade our existing NI 43-101 inferred open-pit resource of 70.8Mtons at 0.018opt gold and 0.189opt silver (0.62gAu/t and 6.49gAg/t). Our technical drilling is near completion and all focus is on the next 20,000m of resource expansion and infill drilling. The underground is on track after SMD did a great job getting through the one difficult section of the decline. Timberline Drilling will be generating deposit infill information before you know it. Much is underway and the project is on schedule, but what shareholders should expect is a lot of news flow. Drill results as we execute our surface and underground programs and catch-up on approximately 5,000m of resource core yet to be logged. Metallurgical news with column results beginning in December and continuing there after as well as important project execution updates. With our OTCQX Best Markets listing we will work hard to get the story and value proposition out to a new set of investors that could not participate before. Improving liquidity will benefit all shareholders as we advance Rosebud and pursue our discovery at Kamma.”

About Blossom Gold Inc.

Blossom Gold is a Canadian-based precious metals exploration and development company that trades on the TSX under the symbol BGAU and the OTCQX under the symbol BGAUF. Blossom Gold 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.
