Golden Arrow advances four gold targets across 10km at Atakama; plans drill

Vancouver, British Columbia--(Newsfile Corp. - July 27, 2026) - Golden Arrow Resources Corporation (TSXV: GRG) (FSE: G6A) (OTCQB: GARWF) (" Golden Arrow " or the " Company ") is pleased to provide an update on its ongoing surface exploration program at the Atakama Gold Project in Chile (" Atakama "). The program has advanced the four priority near-surface gold targets identified to date-Paula, Lolita Norte, Dos Marias and Cerro Sur-across the nearly 10-kilometre width of the property. Key results and observations from the four target areas include: Strong gold grades at surface: The gold in the four zones is mainly structurally hosted in north-to-northwest trending quartz-carbonate-barite-specularite-rich veins and breccia zones with dominant quartz-sericite alteration (see Figure 1).

Paula: 2025 trenching identified a core mineralized zone of 380 metres long by 77 metres wide including five trenches with greater than 1 g/t Au over more than 20 metres (see Figure 3 and Table 1; originally reported January 12, 2026 ). Additional sub-parallel mineralized zones trenched up to 200 m away, and follow-up detailed mapping supports a broader mineralized zone than initially indicated. The target is open in all directions.

Lolita Norte: +3.5 km-long gold-hosting vein system with rock chip sample highlights including 1.5 m @ 4.75 g/t Au and 0.35 m @ 20.5 g/t Au . Dos Marias: +3km-long target with identified gold in extensive shear zones up to 20 metres wide along a northwest-trending structure. Cerro Sur : +8km-long target with highlight rock chip samples of 0.45 m @ 29.72 g/t Au and 1.7 m @ 10.81 g/t Au .

Historic drilling at this target provides the only sub-surface geological information to date. This systematic work has strengthened the Company's understanding of these targets and is guiding the next phase of exploration, including a planned initial drill progr
