Vancouver, British Columbia--(Newsfile Corp. - April 22, 2026) - GoldQuest Mining Corp. (TSXV: GQC) (OTCQX: GDQMF) ("GoldQuest" or the "Company") is pleased to report preliminary visual results from the ongoing exploration drilling program at the Romero deposit in the Dominican Republic.

Recent drill holes LTP-182 and LTP-183 have intersected zones of favorable alteration and mineralization consistent with the Romero deposit style, located outside the current mineral resource block model. These results support the potential extension of mineralization both at depth and along trend of the known mineralization.

Highlights:

• Potential Continuity Beyond Current Resource Limits: Intersected mineralization beyond the current resource model boundaries.
• Consistent Mineralization Style: High-grade mineralization indicators observed are consistent with the main Romero deposit.
• Open System: The Romero mineralized system remains open at depth and laterally along strike.

Drill Results Summary:

• Hole LTP-182: 75-metres step back from hole LTP-137, intersected zones of favourable alteration and mineralization from 220 m to 270 m, and again from 413.75 m to its current depth of 449.73 m (Figures 1, 2 and 3)
• Hole LTP-183: 140 m step back from hole LTP-118. Located to the north-northeast of the main mineralized zone, this hole intersected favourable mineralization from 510 m to its current depth of 555.1 m (Figures 4 and 5).

Although both drill holes LTP-182 and LTP-183 are currently still in mineralization, the current drill rigs have reached their depth capacity. As such, drilling on both holes has been temporarily suspended. The Company is currently mobilizing a more capable replacement drill rig. The new rig is being installed at hole LTP-183 to advance it to its target depth, after which it will be moved to complete hole LTP-182. It is anticipated that drilling will resume by late April.

Geological Interpretation:

The intercepts are visually associated with pyrite-chalcopyrite-sphalerite mineralization, accompanied by moderate to high silica alteration. This mineral assemblage is consistent with the main Romero mineral deposit, supporting the interpretation that these intercepts represent a continuation of the same mineralizing system. Core from both holes is currently being logged, split, and prepared for shipment to the laboratory for assaying. Assays are expected to be received by early June.

The current drilling campaign at Romero is focused on:

• Extending known mineralization beyond the existing resource envelope.
• Improving the geological understanding of mineralization controls.
• Evaluating the potential to increase the overall resource base.

Further drilling is planned to test the continuity, geometry, and grade distribution of these newly identified zones.

Luis Santana, CEO of GoldQuest Mining Corp., commented: "We are encouraged by the visual intercepts observed in drill holes LTP-182 and LTP-183. The mineralization appears visually consistent with the established Romero geological model and supports the continued evaluation of mineralization continuity at depth and along strike. While laboratory assay results are pending, these observations contribute to our ongoing understanding of the geological system."
