Goldquest completes drill program at Romero

Executive Summary

• Goldquest Mining Corp. provided an operational update on its 2025-2026 drilling and metallurgical testwork program at the 100%-owned Romero gold-copper project in the Dominican Republic.
• The company has completed five metallurgical drill holes (1,906m total) with core samples sent to ALS Kamloops for advanced locked-cycle and variability testwork; final results are expected by late April/early May 2026.
• Drilling has commenced at the Cachimbo discovery target (Hole TIR-26-57), currently at 450m with a target depth of 500m, aiming to delineate a mineral resource and test new targets along the Romero-Cachimbo corridor.

Key Details

• Metallurgical Drilling:
  • Completed five metallurgical drill holes totaling 1,906 metres.
  • Approximately 1,600m of representative core selected from all holes for advanced locked-cycle and variability testwork at ALS Kamloops.
  • First metallurgical results expected in March 2026; final report expected by late April/early May 2026.
• Geotechnical and Hydrogeological Drilling:
  • Program includes eight dedicated geotechnical holes (approx. 2,700m total) and ten hydrogeological holes.
  • Status: Three geotech holes completed (1,270m), three continuing; six hydro holes completed, three in progress.
  • All geotech and hydro holes are on schedule for completion by February 2026 to support feasibility study engineering design.
• Cachimbo Discovery Target:
  • Drilling began in early January 2026.
  • Hole TIR-26-57 is currently at 450 metres, with a planned target depth of 500 metres.
  • Core samples show disseminated pyrite, chalcopyrite, barite, and sphalerite in veinlets, similar to previous mineralization at this target.
  • Assay results for Cachimbo anticipated by early March 2026.
• Geophysics Program:
  • Commenced January 27, 2026.
  • Includes gradient array induced polarization (IP) surveys to cover brownfield targets around the Romero deposit.
  • Includes pole-dipole induced polarization (PD-IP) surveys in zones with identified anomalies.
  • Second stage targets the Cachimbo trend to improve drill planning for greenfield targets Canada La Vaca and Los Ganchos.
