Vancouver B.C – TheNewswire - June 9 th 2026 - Golden Goose Resources Corp. (“Golden Goose” or the “Company”) CSE: (CSE: GGR) is pleased to report assay results from its first channel sampling program at the Gran Esperanza Project, located in the Los Menucos District, Río Negro Province, Argentina.

Channel Assay Highlights 1

• 0.70 m grading 8.84 g/t Au from the Bonanza vein (Channel LE_CH26_011)

• 1.14 m grading 3.99 g/t Au from the Chapita vein (Channel LE_CH26_019)

• 0.72 m grading 4.19 g/t Au from the Genaro target (Channel LE_CH26_246)

• 0.70 m grading 2.40 g/t Au from the Felisa target (Channel LE_CH26_071)

• 0.64 m grading 2.49 g/t Au and 49.6 g/t Ag from Chapita West (Channel LE_CH26_024)

1 True widths of mineralized zones and veins described in channel cuts and mapping have not yet been confirmed at this time.

Dustin Nanos, CEO of Golden Goose Resources, commented: “The results from our inaugural channel sampling program at Gran Esperanza are highly encouraging and have met — and in several instances exceeded — our geological objectives for this phase of work. High-grade gold mineralization has been confirmed at surface across multiple parallel structures, and new target areas have been identified in both the western and eastern sectors of the property, meaningfully expanding the known mineralized footprint. The consistency and distribution of results across the property is compelling and has strengthened our confidence in the scale and continuity of this gold system. With a strong technical foundation now in place, we are excited to advance Gran Esperanza toward its next phase of exploration. We look forward to launching a maiden drill program to test mineralization at depth and along strike — results we believe will be critical to defining the depth and lateral extent of a gold system that continues to demonstrate encouraging scale and continuity.”

The 2026 exploration campaign focused on geological mapping of the entire property, detailed geological and structural mapping, and systematic channel sampling. The program successfully confirmed multiple gold-bearing structures, expanded the known mineralized footprint, and identified several new exploration targets. The Bonanza, Dorada and Chapita structures returned the most significant gold grades and represent the highest-priority exploration corridor identified by the current program (Table 1).

Detailed mapping and channel sampling results

The western sector of the property hosts the principal mineralized vein systems identified to date (Figure 1). Outcropping veins are composed of multiple segments associated with granitic intrusive rocks and regional shear zones, forming en-echelon and sigmoid vein geometries with an average apparent thickness of 0.5 meters, locally reaching up to six meters wide.

Quartz veins commonly display comb, drusy, breccia, and minor banded and cockade textures with preserved sulfides as pyrite, chalcopyrite and minor galena-sphalerite. Several targets also exhibit stockwork-style veining surrounding the main structures. Field observations support the potential for at least three hydrothermal pulses, distinguished with minimal alteration halos developed around the veins, and showing pervasive silicification and an argillic alteration composed of illite and sericite.

Geochemical analysis of samples taken from the surface channels indicates that the highest gold-equivalent (> 1 g/t Au Eq.) intercepts are concentrated within the Bonanza Main Target area (Figure 2, Table 1), specifically hosted by the following E-W subparallel segmented vein systems: Bonanza Norte, Bonanza, the vein system Felisa Norte-Dorada-Chapita-Chapita W veins and the Felisa-Laguna southern veins.

These veins show a main structure surrounded by a stockwork or halo of veinlets and are related to strong structural control where regional ENE-WSW faults crosscut with local NW-SE faults, but also with regional NNW-SSE inferred faults.

High-grade (>1.0 g/t AuEq) anomalous channel sample results were also returned from the Genaro and Camino vein systems (Table 1). The Genaro vein comprises an E-W trending quartz vein located north of the Bonanza Main Zone, while the Camino vein corresponds to a WNW-ESE trending structure situated south of the Bonanza Main Zone, suggesting potential continuity and extension of the parallel E-W vein corridor.

In addition, eleven channel samples returned values ranging between 0.5 and 1.0 g/t AuEq, the majority of which are spatially associated with the Bonanza Main Zone.

Mineralization across the vein system is characterized by generally low silver, arsenic, antimony, and base metal contents, indicating a predominantly gold-dominant system.

The Nadia vein, located in the western sector of the property, exhibits a distinct polymetallic Pb-Ag-Zn geochemical signature, returning a 0.53 m channel sample grading 67.9 g/t Ag, 0.47% Pb, and 0.16% Zn, with no significant gold values (Channel LE_CH26_203). Separately, the highest copper value identified during the program was 0.18% Cu over 0.50 m from channel sampling at the Montiel vein. A full listing of channel locations and attributes from the 2026 campaign at Gran Esperanza can be found in Table 2. The Company notes that its news release dated April 22, 2026, stated that 341 channel samples were taken from 265 surface channels; the correct number of channel samples is 324, taken from 264 channels. This change has no impact on the assay results, interpretations, or any other technical information contained in this release.

Rock chip sampling results

In addition to the systematic channel sampling program, the exploration team collected twelve rock chip samples from newly identified vein systems and target areas across the property.

Regional geological mapping led to the discovery of multiple previously unrecognized quartz vein systems in the eastern sector of the project area, a zone with no known historical exploration. These newly identified veins are characterized by comb-textured quartz and appear to be structurally associated with granite foliation and regional shear zones. A total of nine rock chip samples collected from these eastern vein systems returned low-level gold and silver values.

An additional three rock chip samples were collected from newly identified veins in the western sector of the property. One sample returned a significant gold anomaly of 2.65 g/t Au from a 0.30 m wide quartz vein located between the Bonanza Norte and Genaro vein systems.

Sampling and QA/QC

A total of 324 channel samples from 264 channels were cut with a saw machine along continuous sections perpendicular to the mapped veins, with systematic and unbiased sampling. One additional surface channel was mapped and described but no channel samples were submitted for analysis from this channel location ( see Table 2 for all channel locations). Rock-chip samples in the eastern sector were collected along continuous sections perpendicular to the mapped veins. In either case, samples were placed directly into sample bags, each containing two internal sample identification tags, then securely sealed by the geological team. Samples remained under the direct supervision of the geological team until shipped via courier directly to the Alex Stewart International Argentina laboratory in Mendoza, an ISO/IEC 17025 accredited independent analytical laboratory. Samples are prepared with P5 code and then analyzed with fire assay for gold (Au4-50) and multi-elements by ICP (ICP-AR 39). Silver (>200 g/t) over-limits are analyzed by gravity method (Ag4A-50). Seventeen (17) QAQC samples including blanks, Certified Reference Materials, and field duplicates, were inserted into the analytical batch before shipping all material to the laboratory.
