BLOSSOM GOLD RECEIVES APPROVAL FOR NOTICES OF INTENT ON THE RBX CLAIMS AND ROSEBUD WEST TO ADVANCE SITE INVESTIGATIONS FOR PLANNED FACILITIES AND WATER SUPPLY

The U.S. Bureau of Land Management (BLM) has approved notices of intent (NOIs) to conduct site investigation activities on Blossom Gold Inc.'s RBX claims and the Rosebud West area. The RBX claims, located southeast of the Rosebud claim block, are planned to host the project's primary infrastructure, including the ore conveyor, secondary and tertiary crushing, agglomeration and processing facilities, the heap-leach pad, as well as the planned waste rock storage facility. The NOI for Rosebud West is southwest of the Rosebud claims and encompasses the water well field area where water is expected to be sourced for the project.

Highlights:

• RBX and Rosebud West NOIs approved: These NOIs are required to conduct investigations required for project processing facilities locations and project water supply.
• Planned infrastructure investigations: The RBX NOI covers access and condemnation holes, geotechnical test pits and shallow geotechnical probe holes over planned locations for Rosebud's conveying, crushing, heap-leach pad, processing facilities and waste rock storage facility. The Rosebud West NOI allows for the drilling and installation of groundwater monitoring wells as well as test wells in relation to the estimated 5,000-acre-foot-per-annum water supply requirement of the project.
• Permitting and feasibility inputs: Groundwater and geotechnical data collected under the RBX NOI, together with work in the well field area under the Rosebud West NOI, will support facility design and water supply planning for the feasibility study, federal plan of operations and Nevada reclamation permit applications being prepared for the project.

"Receipt of the RBX and West Rosebud NOIs allows us to maintain our critical path for expected, positive federal and state decisions to commence construction at Rosebud in 2029," said Rick Winters, chief executive officer of Blossom Gold. "The RBX claims were originally staked for the purpose of processing and infrastructure and we will conduct confirmation drilling to be sure. Rosebud West encompasses our expected primary water supply for the planned mine and processing facilities. We will be drilling monitoring and test wells as one part of our strategy for securing project water supply. The work on both NOIs will feed directly into permitting and feasibility studies," added Mr. Winters.

"Collecting site-specific groundwater and geotechnical data on the RBX claims is a critical step on our permitting path," stated Alan Haslam, vice-president, permitting, of Blossom Gold. "Baseline hydrogeology and foundation conditions beneath the planned heap-leach pad, waste rock storage and processing facilities are core inputs to the plan of operations and Nevada reclamation permit application we are preparing for submittal to the BLM Black Rock Field Office and the Nevada Division of Environmental Protection, Bureau of Mining Regulation and Reclamation, as well as to the environmental impact statement and feasibility study. Approval of the Rosebud West notice also allows us to advance work in the area where we expect to source the project's water. Starting this work now keeps our permitting timeline aligned with the feasibility study and keeps us on track for construction authorizations for Rosebud by 2029."

Blossom continues to advance the Rosebud project with surface drilling continuing, underground infill drilling expected to commence in December and continuing metallurgical testing, with initial column results beginning in December, all supporting an updated mineral resource estimate expected the end of Q1 2027. Continuing permitting, preliminary engineering and design and work under the RBX and Rosebud West NOIs will support the application for the plan of operations and initiation of feasibility in Q2 2027.

About Blossom Gold Inc.

Blossom is a Canadian-based precious metals exploration and development company that trades on the Toronto Stock Exchange under the symbol BGAU and on the OTCQX under the symbol BGAUF. 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 gold (6.8 grams per tonne gold), when gold prices ranged from $250 (U.S.) to $350 (U.S.); 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 tonnes grading 0.62 g/t Au (0.018 ounce per ton Au) and 6.49 g/t Au (0.189 ounce per ton Au) 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.
