Drilling defines southwest-dipping porphyry-skarn system; new geophysics highlights a cluster of untested porphyry targets

Toronto, May 5, 2026 - Royal Road Minerals Ltd. (TSXV: RYR) (OTCQB: RRDMF) ("Royal Road" or the "Company") is pleased to announce results from the final three drill holes of its recent diamond drilling program at its 100%-owned Güíntar Mining Title, part of the Güíntar-Aleman-Margaritas ("GAM") gold-copper-silver project in Antioquia Province, Colombia (see Figure 1).

These drill results have returned broad skarn-dominated mineralization with local porphyry-style and carbonate-base-metal vein contributions, confirming a large and continuous mineralized system developed around previously reported porphyry-style intercepts (see press release March 18, 2026 and figures 2 and 3). All drilling results are calculated using consistent, mining-constrained parameters, including a 0.25 g/t gold equivalent¹ downhole cut-off and a maximum 10 meters internal dilution. Significant intersections and the complete set of drill results and collar locations are summarized in Tables 1 and 2, respectively.

Porphyry Cluster Identified

Integration of drill core rock-property measurements with newly acquired drone-borne magnetic data and historic induced polarization data has enabled higher-confidence three-dimensional modelling through constrained inversions. This work has identified the continuation of the Güíntar porphyry-skarn system, as well as two new porphyry targets within the GAM project area, Algodona and Niverengo (see Figures 4, 5 and 6). These targets are defined by coincident magnetic and chargeability anomalies, and surface geochemistry but remain largely untested by drilling, significantly expanding the exploration footprint beyond currently drilled areas.

System Understanding

Recent drilling, combined with an updated geological interpretation, demonstrates that the system at Güíntar extends from surface and dips southwestward beneath the skarn envelope (see Figure 2), with multiple drill holes terminating in mineralization and indicating clear continuity at depth. Skarn mineralization forms a laterally extensive outer shell to the porphyry system and is locally enriched in silver. While generally lower grade than the core porphyry mineralization, this broad mineralized envelope supports grade continuity and dilution tolerance within a potential bulk underground mining scenario. In addition, late carbonate-base-metal and quartz-carbonate vein systems locally enhance grade and contribute to the overall metal endowment.

Drill Hole Interpretation

Drill hole GUI-DD-032 was designed to test the transition from skarn to porphyry mineralization and intersected extensive skarn mineralization with localized porphyry-style stockwork developed in the footwall to the main porphyry body. Drill hole CHU-DD-001, drilled from the newly granted Chuscalita title toward the interpreted porphyry center, intersected a long interval of skarn mineralization to end-of-hole, providing a clear vector toward the down-dip continuation of the porphyry system.

Drill hole CHU-DD-002 tested the eastern extent of the Aleman vein system and returned geochemical signatures consistent with movement away from the mineralized center, helping to further constrain the geometry and orientation of the system.

"These final three drill holes complete a program designed to define the geometry and scale of the GAM system," said Dr Tim Coughlin, President and CEO of Royal Road Minerals. "At Güíntar we now recognize a significant porphyry gold-copper-silver system extending from surface and dipping southwestward beneath a broad skarn envelope, with multiple holes remaining open at depth. Importantly, integration of drilling with calibrated geophysics indicates that this system forms part of a broader, concealed porphyry cluster across the GAM project area. These targets remain largely untested and, together with resource definition work at Güíntar, define the next phase of drilling. With work now underway at Margaritas and further results pending, we believe the GAM project has the potential to host a significant multi-center porphyry and skarn system."

About the GAM Project

The GAM project is wholly owned by Royal Road and is located approximately 50 kilometers west of Medellín in the Department of Antioquia, Colombia (see Figure 1). The Project comprises the Güíntar and Margaritas Mining Concession Contracts, in addition to the El Aleman Mining and Chuscalita Mining Concession Contracts. The Güíntar and Margaritas Mining Concession Contracts were obtained through Royal Road's acquisition of Northern Colombia Holdings Limited a wholly owned subsidiary of AngloGold Ashanti Limited (see Press Release May 31, 2019). El Aleman and Chuscalita are subject to option agreements pursuant to which Royal Road holds the exclusive right to acquire a 100% interest (see Press Releases January 12, 2026, and December 14, 2021).
