Blossom Gold Completes Drilling of Metallurgical Core Holes and Begins Delivering Metallurgical Samples to Kappes, Cassiday & Associates to Initiate Metallurgical Testing on Rosebud Mineralization
TORONTO, May 19, 2026 (GLOBE NEWSWIRE) -- Blossom Gold Inc. (“Blossom” or the “Company”) (TSX: BGAU) is pleased to announce that all initially planned metallurgical drill holes at its Rosebud Project in Pershing County, Nevada have been completed. Blossom and Kappes, Cassiday & Associates ("KCA") are now coordinating on the selection of sample intervals to initiate metallurgical test work with the first of several core shipments having arrived at KCA for preparation and initiation of test work.
Eight, larger diameter metallurgical holes totaling approximately 4,000 feet (~1,200 meters) of PQ core have been drilled, targeting all principal host rock types spatially distributed across the Rosebud deposit. Blossom, in coordination with KCA, is in the process of selecting 50-foot intervals of core to provide mineralized samples for bottle roll and column testing to establish precious metal leaching, recovery and material handling information for further heap leach design and engineering. The first five of several sample intervals have been received by KCA and work is underway to prepare samples for testing. Bottle roll testing will begin generating results in 30 to 45 days, providing initial precious metal recovery estimates of the sample intervals in associated columns. Column leaching will begin generating meaningful results in three to six months as mineralization recovery curves are established. As a result, initial column recovery results are anticipated to be available beginning in September and continue through the end of 2026.
"Shipping our first metallurgical core to KCA marks a significant step in derisking the Project and unlocking the economic potential of Rosebud," stated Rick Winters, Blossom Gold’s CEO. "KCA are widely recognized as among the foremost experts in heap leach testing and design, and have always been my go-to experts when evaluating heap-leach opportunities. This test work will provide the data and information required for continued design and as input to feasibility studies. We anticipate positive precious metal recovery results based on what we have seen in core and look forward to sharing results with the market as they become available."
Current drilling at Rosebud is focused on: 1) geochemistry requirements to initiate long lead, humidity cell testing for environmental assessment; 2) hydrological and geotechnical holes to support environmental assessment and feasibility studies; and 3) exploration drilling to expand and upgrade the Rosebud deposit. We expect to begin generating assay results on exploration drilling beginning in June and continuing through the end of 2026.
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.
