Exploration Programs

GoldQuest Commences 2025 Drilling Program

at Romero Gold-Copper Project, Dominican

Republic

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.
