GOLDQUEST PROVIDES UPDATE ON DRILLING AND EXPLORATION ACTIVITIES AT ROMERO GOLD-COPPER PROJECT, DOMINICAN REPUBLIC

Goldquest Mining Corp. has provided an update on its continuing 2025 to 2026 drilling and metallurgical testwork program at the 100-per-cent-owned Romero gold-copper project in the Dominican Republic.

• The company has successfully completed the metallurgical drill program: five metallurgical drill holes totalling 1,906 metres; approximately 1,600 m of representative core selected from all holes for advanced locked-cycle and variability testwork at ALS Kamloops, with first results expected in March, 2026, and the final report by late April/early May, 2026.
• Geotechnical and hydrogeological drilling advancing on schedule: eight dedicated geotech holes (approximately 2,700 m), of which three were completed and three are continuing, and 10 hydrogeological holes (six completed, three in progress) all to be finished by February, 2026, to support feasibility study engineering design.
• Drilling started in early January at the Cachimbo discovery target, with the first hole currently at 450 metres, with a planned target depth of 500 metres. This program aims to delineate a mineral resource and test additional targets along the Romero-Cachimbo corridor.
• Geophysics program under way: A new ground geophysics program has commenced to further refine exploration targets. The program consists of gradient array induced polarization (IP) surveys and pole-dipole induced polarization (PD-IP) surveys.

Since beginning the program in September, 2025, the company has completed five metallurgical drill holes totalling 1,906 metres and three dedicated geotechnical holes totalling 1,270 metres. These data will support the continued development of the underground mining design.

In parallel, three additional drill rigs continue with a geotechnical and hydrogeological drilling program at the planned plant, waste dump, tailings facility areas and critical infrastructure. This campaign has been updated to eight dedicated geotechnical holes (approximately 2,700 metres in total) and ten hydrogeological holes (six completed and three continuing) and is on schedule for completion by February, 2026. Data from these holes will support detailed engineering design for the feasibility study.

Luis Santana, chief executive officer of Goldquest Mining, commented: "We are advancing efficiently on all fronts. With metallurgical samples now at the lab and the drill bit turning at Cachimbo, we remain on schedule to deliver our feasibility study milestones while simultaneously exploring the district's potential."

At Cachimbo, drilling of hole TIR-26-57 began in early January and has now reached 450 metres, with a target depth of 500 metres. The program seeks to define a mineral resource and test new targets along the Romero-Cachimbo corridor.

Core samples from TIR-26-57 contain sections with disseminated pyrite, chalcopyrite, barite and sphalerite in veinlets, similar to mineralization encountered in previous holes at this target. Cutting and sampling are currently in progress, with assay results anticipated by early March.

Additionally, a geophysics program is currently in progress. commenced on Jan. 27, a new ground geophysics plan aims to further delineate exploration targets and support drill planning along the aforementioned corridor. The scope of this program includes gradient array induced polarization (IP) surveys, which will be supplemented with pole-dipole induced polarization (PD-IP) surveys in zones where anomalies are identified. The plan consists of:

• A first stage of gradient array induced polarization (IP) to complete the cover in the brownfield targets around the Romero deposit;
• A second stage targeting the Cachimbo trend, with the objective of improving the upcoming drill program at the greenfield targets Canada La Vaca and Los Ganchos.
