AI-generated analysis. Not financial advice.
Positive
- High-grade CBM vein in MAR-DD-002: 4m at 651 g/t silver and 0.47% antimony
- Multiple CBM intercepts including 5m at 377 g/t silver and 0.28% antimony in MAR-DD-003
- Broad mineralized intervals: MAR-DD-003 returned 304m at 0.3 g/t gold equivalent from surface
- Margaritas lies 4km south of the Güíntar porphyry discovery within the GAM project
- Company interprets Margaritas as part of a larger hydrothermal system with porphyry-related potential
Negative
- Company states broad 0.3 g/t gold equivalent intervals are not economically significant at this stage
- True widths of all drill intersections are unknown due to insufficient geological information
- Drill holes MAR-DD-001 and MAR-DD-002 terminated in syn- to late-mineralization granodiorite, limiting depth testing
- Project remains at an early exploration stage and requires further drilling and vectoring studies
Toronto, Ontario--(Newsfile Corp. - June 9, 2026) - Royal Road Minerals Limited (TSXV: RYR) (OTCQB: RRDMF) ("Royal Road" or the "Company") is pleased to announce results from its first exploratory diamond drilling program at the Margaritas target, part of the Company's wholly owned Güíntar-Aleman-Margaritas ("GAM") gold-copper-silver project in Antioquia Province, Colombia (see Figure 1).
Initial drilling at Margaritas comprised four scout diamond drill holes for a total of 1,154 meters and has identified a broad polymetallic hydrothermal system developed within altered volcanic and intrusive rocks. Mineralization occurs as hydrothermal breccias, stockwork vein systems, quartz-tourmaline breccias and sulphide-rich alteration zones carrying low-grade gold-silver mineralization with locally elevated copper values. These broader mineralized zones are crosscut and locally upgraded by later silver-antimony carbonate-base-metal ("CBM") veins and breccias, which have returned high-grade silver and significant antimony values over mineable widths (see Figures 2 and 3).
Notable Drill Results
SILVER-ANTIMONY CARBONATE-BASE-METAL (CBM) VEIN AND BRECCIA INTERSECTIONS
| MAR-DD-001 | From 155 to 158 meters: 3m at 204 g/t silver and |
| (3.5 g/t gold equivalent1) | |
| MAR-DD-002 | From 177 to 181 meters: 4m at 651 g/t silver and |
| (11.3 g/t gold equivalent) | |
| MAR-DD-003 | From 102 to 112 meters: 10m at 50 g/t silver and |
| (1.3 g/t gold equivalent) | |
| MAR-DD-003 | From 171 to 176 meters: 5m at 377 g/t silver and |
| (6.9 g/t gold equivalent) | |
| MAR-DD-004 | From 48 to 52 meters: 4m at 191 g/t silver and |
| (3.6 g/t gold equivalent) |
HYDROTHERMAL BRECCIA, STOCKWORK AND TOURMALINE BRECCIA INTERSECTIONS
| MAR-DD-004 | From 100 to 123 meters: 23m at 1.0 g/t gold equivalent |

System Interpretation
Drill holes MAR-DD-003 and MAR-DD-004 returned 304 meters and 231 meters respectively at 0.3 g/t gold equivalent from surface to end-of-hole. While these intervals are not considered economically significant, they highlight the scale of hydrothermal alteration and mineralization encountered at Margaritas.
Drill holes MAR-DD-003 and MAR-DD-004 intersected altered volcanic and intrusive rocks hosting broad zones of hydrothermal breccia, stockwork veining, quartz-tourmaline breccias and sulphide-rich alteration characterized by low-grade gold-silver mineralization with locally elevated copper values. These broader mineralized zones are interpreted to represent the outer expression of a larger hydrothermal system.
Quartz-tourmaline breccias are commonly associated with the broader low-grade hydrothermal system and appear to represent pathways for hydrothermal fluids rather than the principal hosts to high-grade silver-antimony mineralization.
These broader mineralized zones are locally overprinted and upgraded by carbonate-base-metal ("CBM") veins and breccias carrying elevated silver, antimony, lead and zinc values. The highest-grade silver and antimony intersections reported to date are associated with this later mineralizing event.
Drill holes MAR-DD-001 and MAR-DD-002 tested the strike continuity of later silver-antimony carbonate-base-metal veins and breccias. These holes confirmed high-grade silver-antimony mineralization over mineable widths but terminated in a syn- to late-mineralization granodiorite.
District-Scale Implications
Margaritas is located approximately four kilometers south of the Güíntar porphyry discovery and approximately three kilometers south of the Algodona target. Recent drilling at Güíntar, combined with geophysical modelling and geological interpretation, has highlighted the potential for a cluster of mineralized porphyry centers within the GAM project area (see Press Release May 5, 2026).
The geological and geochemical characteristics observed at Margaritas suggest a relatively distal position within this broader mineralized environment. Surface geochemistry, petrography and geological mapping indicate increasing exploration potential toward the south and at depth.
While it remains early in the exploration process, the Company believes Margaritas may represent part of the broader hydrothermal footprint associated with the emerging GAM porphyry cluster. Further drilling and vectoring studies will be required to determine the relationship between Margaritas and nearby porphyry targets.
"We knew from geochemical studies and alteration mapping prior to drilling that near-surface mineralization at Margaritas was located at some distance above or adjacent to a potential porphyry target," said Dr Tim Coughlin, President and CEO of Royal Road Minerals. "The high-grade silver-antimony veins were not obvious on surface and are a pleasant surprise. Together with the broader mineralized zones identified during drilling, they further corroborate the distal model and provide important vectors toward the porphyry target. Now that all drill results are in hand, we will commence detailed geochemical and geophysical vectoring studies designed to locate follow-up drill holes aimed at identifying the primary source of the hydrothermal system while continuing to evaluate the economic potential of the high-grade silver-antimony veins."
