Blossom Gold names Graden Colby as COO and Executive Director

TORONTO, May 06, 2026 (GLOBE NEWSWIRE) -- Blossom Gold Inc. (“ Blossom ” or the “ Company ”) (TSX: BGAU) is pleased to announce the appointment of Graden Colby as Chief Operating Officer effective May 12, 2026. Mr. Colby will remain on the Board as Executive Director. Concurrently, Brandon Throop has assumed the expanded role of Vice President, Corporate Development & Investor Relations.

Graden Colby is a seasoned mine developer and operations leader with over 20 years of progressive experience in underground and open pit mining in Nevada. Graden is known for building high-performance teams and delivering results in complex, large-scale environments and brings an exceptional track record in safety leadership, operational execution, and mine development to Blossom. Most recently, Mr. Colby spent over five years at Nevada Gold Mines, where he oversaw better than 5Mtons/year underground operations producing over 900,000 ounces of gold annually as well as over 60Mtons/year of open pit production.

Prior to that, Graden spent 14 years at Newmont Mining Corporation in roles of increasing responsibility, including as Mine Manager at the Leeville operations and the Carlin Portal Mines. Earlier in his career at Newmont, he served as Superintendent at Carlin Portal Mines and General Foreman at the Midas Mine. Mr. Colby holds a Bachelor of Science in Mining and Mineral Engineering from the Colorado School of Mines.

Rick Winters, CEO of Blossom, stated: "I have always told investors that you do not want bankers building mines. Blossom shareholders and stakeholders need not be concerned about our ability to advance Rosebud. Graden’s depth of experience with several Nevada gold mining operations, combined with his reputation for building strong teams, safety programs and delivering results, makes him an ideal fit.

There could be no clearer testament to our intentions of building a mine than the addition of an operator of Graden's caliber to our senior leadership team. We all look forward to working with Graden and the contributions he will make as we continue to derisk and unlock the potential of this very exciting project.” Graden Colby, Blossom’s Chief Operating Officer, commented: “Rosebud is a compelling development asset in the best gold mining jurisdiction in the United States. It was a relatively easy decision to serve as Director after reviewing the extensive historic database on the Project.

While on the Board, I have watched Blossom assemble a strong, capable team that is executing a focused deposit expansion and infill drilling program, permitting and development effort aimed at initiating a feasibility study in 2027 for a major open pit, heap leach operation. This experience and my belief in Rosebud made accepting the role as Chief Operating Officer and Executive Director a no brainer. I look forward to working alongside Rick and the team to ensure we continue to perform in advancing the Company through all the milestones required to advance Rosebud to production.” 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 g/t Au), 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.
