Toronto, Ontario – May 27, 2026 – Galleon Gold Corp. (TSXV: GGO) (OTCQX: GGOXF) (FSE: 3H90) (the “Company” or “Galleon Gold”) announces results of a drill intercept in a highly strategic location at its 100%-owned West Cache Gold Project (the “Project” or “West Cache”) in Timmins, Ontario. The intercept further reinforces the potential scale and significance of Zone #9.

WC-26-237 Highlights

• WC-26-237 with 12.69 g/t Au over 12.35 m including 16.07 g/t Au over 9.25 m
• High grade hosted in a broad intercept of 4.07 g/t Au over 40.9 m
• Intercept is located 275 meters down-dip from high grade Zone #9 intercepts and the area of the planned bulk sample

“Intersecting 16.07 g/t gold over more than 9 meters — within nearly 41 meters grading 4.07 g/t gold — is one of the most significant drill holes completed to date at West Cache, and results of this scale and grade have the potential to materially enhance the economics of the Project,” said David Russell, CEO & President. “This intercept also provides strong confidence that the mineralized shoot extending from the 2020 discovery of Zone #9 near surface down to the historic West Deep drilling may in fact be continuous, or that we are dealing with multiple high-grade shoots. Credit goes to our VP Exploration, Leah Page, who planned and is executing this highly successful 2026 drill program.”

How This Drilling Corridor Relates to the Bulk Sample

Over the past several months, the Company has provided regular updates on its planned, fully financed 86,500 tonne bulk sample program. Surface construction has advanced on schedule, with completion of the access roads, hydro line, and box cut excavation. The bulk sample is designed to extract Zone #9 material between the 150m and 210m levels.

The WC-26-237 intercept is located approximately 295 meters down-plunge (275 meters down-dip) from the planned bulk sample stopes and 440 vertical meters below surface. Approximately 200 meters of the projected plunge between the bulk sample area and the high-grade intercept remains untested.

Geological Overview of WC-26-237 Intercept

The high-grade intercept in WC-26-237 is hosted in sheared greywacke, siltstone, and mudstone of the Porcupine Assemblage. Semi-massive to massive sulphide and “buckshot” bands of pyrite, red sphalerite, and chalcopyrite comprise the dominant mineralization style, along with fine-grained, disseminated pyrite. Low angle (relative to core axis) structures and ductile deformation that crosscut the dominant foliation and bedding are evident up to 75-meters into the zone’s hanging wall and persist through the mineralized footwall. Shearing and deformation are most pronounced in the hanging wall and footwall of the intercept where tight folding, kink bands, and en-echelon tension gashes are prominent. While the structural indicators are apparent in higher-elevation intercepts on Zone #9 in the planned bulk sampling area, their intensity is greater in the WC-26-237 intercept. The mineralization style, structural features, and grade continuity are key indicators that the WC-26-237 intercept is part of the Zone #9 system at depth.

As stated in the Company’s 2022 Preliminary Economic Assessment, an interpretation of a northerly-northwesterly plunge of Zone #9 was being evaluated, which aligns with the WC-26-237 intercept. The plunge was first tested with WC-26-236 (assays pending) which was drilled 75-meters to the east of WC-26-237. Following the WC-26-237 intersection, the Company attempted to offset the high-grade intercept lower on the projected plunge with WC-26-238, and higher on-plunge with WC-26-240. Assays from those holes are also pending.

Figures and Tables

Figure 1 and 2 show cross-sectional views of holes WC-26-236 to WC-26-240 in relation to other Zone #9 intercepts and the West Deep while Figure 3 provides core photos of the intercept’s high-grade sulphide mineralization and the mineralized footwall approximately 30-meters below the intercept. Table 1 outlines the composited assay intervals and true thickness estimation for the high-grade intercept. The drill hole intersection of the mineralized zone was nearly perpendicular, as shown in the core photos in Figure 3. The WC-26-237 intercept along with logging information from WC-26-236, WC-26-238 and WC-26-240 have prompted reinterpretation of the Zone #9 longitudinal section, which is pending the receipt of assay data from the other 2026 intervals.

Quality Assurance (QA) / Quality Control (QC)

Quality Control and Assurance procedures and protocols are executed to ensure sampling and analysis of all exploration work is conducted in accordance with best practices. Core produced at the West Cache Property is delivered to the Company’s Timmins logging facility by the drill contractor with all logging, cutting, labeling, and bagging completed under supervision of Qualified Geologists. NQ sized core is predominantly sawn in half with one half of the core prepared for shipment, while the other half is retained for future assay verification.

Core samples are transported from the Company’s Timmins logging facility to AGAT Laboratories in Thunder Bay, Ontario for both prep and 30g fire assay analysis. Results are reported in batches of 60-72 samples and average 4-5 QC samples per certificate. Commercially prepared certified reference material (CRM) and duplicate samples are inserted at an average rate of 6% to 8%.  At least one blank, standard and duplicate (pulp or coarse) is inserted for every 50 samples and additional QC samples are inserted at the Geologist’s discretion. All samples reported have been checked against the Company’s internal, and the Lab’s, quality control samples.
