GoldQuest Commences 2025 Drilling Program at Romero Gold-Copper Project, Dominican Republic

Rhea-AI Summary

GoldQuest (OTC:GDQMF) has started its 2025 drilling program at the Romero gold-copper project in the Dominican Republic, the first drilling at Romero since 2018. Current activity includes hole LTP-171 at 220 metres targeting metallurgical testwork, a second rig mobilized for additional metallurgical holes, and plans to deploy a third rig to Cachimbo for a 5,000-metre greenfield exploration program in early November. Recent technical work completed or underway includes 3D structural modelling, geophysics reprocessing, and relogging/mapping.

Key status metrics: Romero structural analysis 100%, Romero geophysics 75%, Cachimbo geological model 100%, greenfields mapping/trenching 50% with 62 trenches completed and assays confirming surface gold mineralization.

Positive

• Drilling resumed at Romero for the first time since 2018
• Active 220 m metallurgical hole LTP-171 underway
• Planned 5,000 m Cachimbo greenfield drill program in early November
• Completed 62 trenches with assays confirming surface gold mineralization

Negative

• Romero geophysics program only 75% complete

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."
