 Vancouver, British Columbia--(Newsfile Corp. - October 9, 2025) - GoldQuest Mining Corp. (TSXV:   GQC) ("GoldQuest" or the "Company") is pleased to announce the   commencement of its 2025 drilling campaign at the Romero Gold-Copper   Project, located in the Dominican Republic.
 
 This program marks  the  first drilling completed at Romero since 2018 and represents an   important step forward in advancing the Company's strategy to both   develop the Romero Mineral Resource and test high-priority greenfield   targets across the Tireo Belt (Figure 1).

 GoldQuest   is currently drilling hole LTP-171 (Figure 2), which has reached a   depth of 220 metres, focused on metallurgical testwork to support the   Romero development studies. A second drill rig, already mobilized, will   commence further metallurgical drill holes later this week. The Company   also plans to mobilize a third drill rig to the Cachimbo target to  begin  a 5,000-metre greenfield exploration program in early November,  aimed  at expanding gold-copper resource potential within the belt.

 Recent   technical work has included a comprehensive review of district and   local structural geology, which enhances the understanding of   gold-copper mineralization controls and informs ongoing 3D structural   modelling. GoldQuest has also been working with a senior geophysicist to   reprocess and reinterpret historical geophysical datasets, improving   the targeting of both brownfield and greenfield prospects.
 
 Status of key technical activities:
 
 
 | Target | Task | Completion % | Comments |  | Romero | Structural Analysis | 100% | Relogging and mapping completed; supports resource update and metallurgical test planning. |  | Romero | Geophysics | 75% | Downhole magnetic data assessment complete; additional ground magnetic lines scheduled; 3D inversion model in progress. |  | Cachimbo | Geological Model | 100% | Geological reinterpretation completed; 3D model under development to guide drill hole design. |  | Greenfields | Mapping and Trenching | 50% | 62 trenches completed; assays confirm gold mineralization in surface zones; further trenching ongoing. | 
 
 Luis Santana, CEO of GoldQuest Mining Corp., commented: "With   drilling now underway at Romero, we are executing on both our   development and exploration objectives for the year. Our team's recent   work has strengthened our geological understanding and refined our   gold-copper exploration targeting across the Tireo Belt. These programs   are designed to de-risk the project and build shareholder value as we   continue advancing Romero and unlock additional discovery potential in   the region."
