Royal Road Mineral Provides Update: Guintar -Margaritas Project, Colombia

Rhea-AI Summary

Royal Road Minerals (OTCQB: RRDMF) has provided an update on its Güíntar-Margaritas Project in Colombia's Antioquia region. The project has revealed significant gold, copper, and silver mineralization through 45 diamond drill holes, with mineralization extending from surface to depths over 250 meters.

Notable intersections include 62m at 2.1 g/t gold, 12.4 g/t silver & 0.6% copper in porphyry-style drilling, and 24m at 2.4 g/t gold in vein-gold-style drilling. The company owns 100% of the project following a reorganization with Mineros S.A. in May 2023.

The project comprises multiple mining concessions and includes an artisanal mining district with over 50 underground workings. Royal Road is now preparing to recommence work at the site with support from state and local authorities.

Toronto, Ontario--(Newsfile Corp. - September 29, 2025) - Royal Road Minerals Limited (TSXV: RYR) (OTCQB: RRDMF) ("Royal Road" or the "Company) is pleased to announce that it has been collaborating with state and local authorities and engaging with the local community and other stakeholders with a view to recommencing work at its key Colombian exploration asset, Güíntar -Margaritas.

Güíntar -Margaritas is a combined skarn, vein-gold and, recently discovered, copper-gold-silver porphyry system located in Antioquia region, Colombia (Figure 1). Exploratory drilling has revealed that both vein gold and porphyry-style gold-copper-silver mineralization extends from surface and continues to depths in excess of 250 meters. A total of 45 diamond drill holes have been completed at Güíntar, 50% of them have terminated in gold grades considered to be anomalous and indicating further potential at depth (see also Table 1 and Figure 2).

The Güíntar -Margaritas Project ("GM") 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 Concession Contract and Mining Application "Güíntar North" (see Figure 2). The Güíntar and Margaritas Mining Concession Contracts were obtained through Royal Road's acquisition of Northern Colombia Holdings Limited ("NCH"), a wholly owned subsidiary of AngloGold Ashanti Limited ("AGA", see Press Release May 31, 2019). El Aleman and Mining Application "Güíntar North" are subject to option agreements pursuant to which Royal Road holds the exclusive right to acquire a 100% interest (see Press Release December 14, 2021). Following the acquisition of NCH, Royal Road entered into a 50:50 strategic exploration alliance with Mineros S.A. (TSX: MSA; MINEROS:CB) in respect of the GM project (see Press Release March 3, 2020). In May 2023, Royal Road and Mineros reorganized their joint venture interests resulting in Royal Road assuming 100% ownership of the GM project (see Press Release May 31, 2023).

The GM project area contains an artisanal mining district with more than 50 underground workings developed on steeply-dipping, east-west oriented gold mineralized vein structures. AGA secured title and commenced work on the project area in 2015. AGA conducted geological mapping, soil geochemistry, ground magnetics, IP, airborne magnetics and radiometrics and two scout drilling campaigns at Güíntar. 16 diamond drill holes totaling 5,663 meters were located on gold vein and skarn-style exploration targets. The Margaritas project was a Mining Concession Application which limited AGA's work to surface investigations comprising airborne magnetics and radiometrics, geologic mapping and ridge and spur soil sampling. The Margaritas Application was converted to a Mining Concession Contract by Royal Road in August of 2021 (see Press Release August 31, 2021) and is now fully permitted for drilling.

In 2020, following the acquisition of NCH, Royal Road completed an initial 1,179 meter scout diamond drilling program at Güintar. Drilling focused on skarn-style mineralization in the west of the concession area (Niverengo prospect, see Figure 2 and Press Release September 29, 2020) and intersected gold-silver and copper mineralized pyrrhotite vein-breccia bodies hosted in calc-silicate altered sedimentary rocks (see Figure 2 and Table 1).

In July of 2021, following a detailed technical review, Royal Road initiated a 17-hole, 6287 meter, diamond drilling program at Güintar, aimed specifically at testing for porphyry-style potential located subjacent to vein-gold and skarn-style mineralization. Drilling intersected dense, aligned stockworks of porphyry-style veinlets extending from locally concealed surface outcrops to depths in excess of 140 meters, with wall-rock characterized by lower-grade but consistent gold, copper and silver mineralization down to depths in excess of 300 meters (see Figures 2 and 3 and Table 1; Press Releases December 14, 2021, April 28, 2022, June 28, 2022).

Surface saw-cut channel sampling extended known outcrops of porphyry mineralization northwards, beyond the extents of the Güintar Mining Concession Contract, onto the "Güintar North Application" area. Channel samples returned; GUI-CH-002, 24.2 meters at 0.9 grams per tonne gold, 16.2 grams per tonne silver and 0.3% copper and channel GUI-CH-003, 15.7 meters at 0.9 grams per tonne gold, 9 grams per tonne silver and 0.5% copper (see Figure3 and Press Release April 28, 2022).

Drill hole ALM-DD-001 is the first exploratory drill hole to have been completed on the El Aleman property (see Figures 2 and 4). The drill hole targeted the depth extent of mine workings located on an east-west oriented zone of quartz-carbonate gold-rich polymetallic veins and intersected; ALM-DD-001, 24m at 2.4 g/t gold within 80.5m at 1.0 g/t gold equivalent (see Table 1), extending gold mineralization from surface to at least 270 meters vertical depth. ALM-DD-002 was drilled beneath ALM-DD-001 but failed to intersect the sheeted vein zone (intersected thin zones of low-grade gold; see Figure 4, Table 1).

Royal Road has conducted grid-based soil geochemical sampling, rock-chip sampling and mapping at the Margaritas project (see Figure 5). Results from rock-chip sampling returned up to 34 grams per tonne gold (minimum 0.002 and mean 0.2 grams per tonne), 3,160 grams per tonne silver (minimum 0.005 and mean 18.2 grams per tonne) and 0.8% copper (minimum 2.2 ppm and mean 0.02%). The Margaritas project is fully permitted and ready for drill-testing.

"We are most grateful for the renewed initiative and support from the Colombian Mining Agency and of course for the continued encouragement from our local communities at Guintär and within the municipality of Anza," Said Dr Tim Coughlin, Royal Road's President and CEO. "It is our opinion that Guintär and Margaritas are key components of a newly emerging metallogenic district, with exploratory drilling providing unambiguous evidence of along strike and particularly depth potential for significant porphyry, sheeted vein and skarn-style, gold, copper and silver mineralization. We are anxious to recommence work and have laid out a preliminary program aimed at refining our understanding of geometry and carefully extending drill holes away from and beneath known accumulations of higher-grade material."
