Goldquest Mining Announces Progress on 2025 Exploration Program in the Dominican Republic

Vancouver, British Columbia--(Newsfile Corp. - July 24, 2025) - GoldQuest Mining Corp. (TSXV: GQC) ("GoldQuest" or the "Company") is pleased to announce the first progress on its 2025 Exploration Program.

The Company continues to advance its dual-track strategy: the development of the Romero Project and a renewed focus on regional exploration within the Tireo Belt. Over the spring months, GoldQuest's Exploration team carried out an extensive program of trenching and channel sampling across Greenfield targets in the belt.

These efforts are aimed at narrowing down high-priority drill targets for a planned drill campaign of at least 5,000 metres, expected to commence in Q3 2025. This marks an important milestone for the Company, as it will be the first drilling since the 2018 campaign.

Luis Santana, CEO of GoldQuest Mining Corp., commented: "As we move forward with the Romero Project following the receipt of our Terms of Reference, we're equally focused on unlocking the broader potential of the Tireo Belt. Our Exploration team has been working diligently, and we're now beginning to see results that will guide our upcoming drill program. These efforts are key to creating long-term shareholder value while continuing to advance Romero."

GoldQuest has also contracted a specialist in structural geology to assist with the structural modelling of the projects and has a senior geophysicist reprocessing existing down-hole magnetic susceptibility data together with the raw data from the ground magnetic surveys. The GQC Exploration team has now implemented a modern, cloud-based database platform (MX Deposit) to organize the existing geological information, add new data and make it easily available for its analysis.

All this work is expected to culminate in a robust, integrated geological model to assist with targeting and drilling planned to start during Q3, 2025.

Target Task Completion Comments
Romero Structural 
Analysis
25% Relogging and mapping to improve current understanding of the Romero Mineral Resource area to unlock its full potential.
Romero Geophysics 15% Completed an assessment on the downhole magnetic susceptibility data. Additional lines to improve ground magnetic resolutions are planned to start on Q3.
A full 3D inversion model to be generated as final product.
Cachimbo Geological 
Model
75% Full relog completed, ongoing cross sections and longitudinal sections interpretations. 3D geological model expected by early Q3, allowing to improve geological concepts, mineralization and drill planning.
Greenfields Mapping and Trenching 50% 62 trenches in 3 targets completed (Los Mineros, Cañada La Vaca, Los Gauchos). Results from first two batches confirms initial finding of gold mineralization at surface, opening potential for higher grades at depth.

At Cañada La Vaca and Los Ganchos, results highlight a NW trending corridor of +4 km with gold mineralization at surface (consistent values >1 g/t in rock chips and trenches), robust soil anomalies (Au+Ag+Cu) and IP chargeability anomalies. Adding in results from the Cachimbo area, this trend extends to a +7.5Km trend as shown on the Figure 1 map below.

GoldQuest is entering an exciting new phase of growth and development. After years of dedicated work in community engagement and constructive dialogue with government authorities, the company is now poised to advance the full potential of its highly prospective land package. With the recent receipt of the Terms of Reference for the Environmental and Social Impact Assessment (ESIA) of the Romero Project, GoldQuest is thrilled to move forward with the environmental studies at Romero and to resume exploration activities across the broader Tireo Belt, including the highly promising Cachimbo area.
