Royal Road Minerals Limited (TSXV: RYR | OTCQB: RRDMF) has announced the commencement of diamond drilling at the Güíntar target within its GAM gold-copper-silver project in Antioquia, Colombia. The new drill program targets down-plunge and down-dip extensions of mineralization identified in two previously drilled holes that returned significant gold-equivalent intercepts. The announcement also outlines encouraging sampling results at Algodona and a newly defined geophysical target at Niverengo, while the company's broader Colombian exploration portfolio spanning approximately 1,840 km² continues to advance.

Key Points

  • Royal Road Minerals Limited (TSXV: RYR | OTCQB: RRDMF) is a mineral exploration and development company exploring in Colombia, Saudi Arabia, and Morocco.
  • Diamond drilling has commenced at Platform 20 at Güíntar, targeting extensions of mineralization below previous drilling limits.
  • Prior holes GUI-DD-013 and GUI-DD-028 returned 131 metres at 1.0 g/t AuEq and 176 metres at 1.2 g/t AuEq respectively; GUI-DD-028 remained open at depth.
  • Algodona underground sampling returned 36 metres at 2.14 g/t gold and 6.95 g/t silver, and Niverengo has a newly defined coincident chargeability and magnetic target.

Güíntar Drill Program Targets Depth Extensions of Known Mineralization

Drilling at Platform 20 is designed to follow the interpreted mineralized system down-plunge and beneath the footprint of earlier campaigns. The program also includes drilling from Platform 19 to test the width and continuity of mineralization across adjacent fault-bound structural blocks. Recent geological work indicates that the Güíntar porphyry system has been locally offset by younger normal and transtensional faulting, and that these structures are themselves mineralised by a later pyrrhotite-hosted gold-bearing hydrothermal event — a finding the company states provides a substantially improved targeting framework for both mineralising phases.

Widespread Pyrrhotite-Hosted Gold Event Identified Across GAM

Selective resampling of pyrrhotite-bearing veins from historical drill core at Güíntar and Niverengo returned gold values ranging from 0.15 to 69.5 g/t Au across 21 samples, with a median grade of 1.17 g/t Au. The company notes that 17 of those samples returned at least 0.5 g/t Au. Royal Road interprets the widespread distribution of pyrrhotite veins and disseminations across Güíntar, Alemán, Niverengo, and Algodona as evidence of a broad, uplift-related hydrothermal flooding event superimposed on the earlier porphyry system, with pyrrhotite's magnetic response offering an exploration vector toward concealed intrusive-hydrothermal centres.

Algodona Sampling and Niverengo Geophysics Expand GAM Target Inventory

At Algodona, continuous rock-chip sampling from two artisanal workings returned 36 metres at 2.14 g/t gold and 6.95 g/t silver, plus a secondary interval of 11 metres at 1.49 g/t gold. The company states that integration of drilling, underground sampling, and geophysical data supports the interpretation of a concealed intrusive-hydrothermal centre surrounded by mineralised skarn. At Niverengo, reprocessing of historical induced-polarisation data has identified an untested chargeability anomaly exceeding 40 mV/V coincident with a magnetic susceptibility high, with historical drilling having been completed principally outside the core of this target.

Northern and Southern Colombian Blocks See Parallel Advancement

Across Royal Road's broader Colombian holdings of approximately 1,840 km², field programs have been completed at Cangrejo and Ebéjico in the Northern Block, with follow-up work progressing at La Merced, where channel sampling along approximately 140 metres of road-cut returned an average grade of 1 g/t gold. In the Southern Block, the company is engaging with government, communities, and stakeholders in Cauca and Nariño to progressively reopen prospective gold and copper targets to systematic exploration. The immediate share price impact was not clear from available public information.
