GoldQuest Provides Update on 2025 Drilling and Metallurgical Program at Romero Gold-Copper Project, Dominican Republic

The most recent news release from December 3, 2025, provides an update on GoldQuest Mining Corp.'s 2025 drilling and metallurgical program at its Romero Gold-Copper Project in the Dominican Republic. The company reports the completion of its metallurgical drilling campaign, which involved 5 holes totaling 1,906 meters, ahead of schedule. Approximately 1,600 meters of core have been selected for advanced metallurgical testwork.

Furthermore, geotechnical and hydrogeological drilling, comprising 5 holes (around 1,600 meters) and an additional 12 holes, is progressing as planned and is on schedule for completion by February 2026.

The company also announced that additional drilling rigs are being mobilized to the Cachimbo discovery target, with the first rig expected to start in early December 2025 and a second rig by late January 2026. This drilling at Cachimbo is aimed at resource delineation for exploration targets. Concurrent with these activities, new datasets are being integrated into AI targeting software to enhance exploration efforts.

CEO Luis Santana expressed satisfaction with the "rapid and safe progress" of the 2025 program, highlighting the completion of metallurgical drilling and securing representative samples as an "important de-risking milestone" for the Romero Project. He also noted the anticipation for commencing greenfield exploration drilling at Cachimbo.

The December 3, 2025, news release details the ongoing execution of GoldQuest's 2025 work programs at its Romero and Cachimbo projects. This news is generally positive as it confirms that the metallurgical drilling campaign has been completed on schedule, which the CEO explicitly refers to as a "de-risking milestone." The planned geotechnical and hydrogeological drilling for the Romero development studies is also on track.

The mobilization of additional rigs to the Cachimbo target for resource delineation is a direct follow-through on previous announcements (October 9, 2025 news mentioned a third rig for Cachimbo in early November, and July 24, 2025 news discussed greenfield exploration). This demonstrates consistent execution of the company's stated exploration and development strategy.

This news confirms progress and successful execution of operational plans, aligning with the company's previously communicated objectives. It does not contain new assay results, resource updates, or significant financial events that would materially alter the company's valuation in the short term. Instead, it indicates a steady advancement of the Romero project towards a Bankable Feasibility Study (BFS) and continues the greenfield exploration efforts. Given the nature of a progress update without definitive results, this news is assessed as "Routine - Positive," signifying good operational management and project advancement without being a game-changer. It maintains investor confidence in the company's ability to execute its technical programs.
