Royal Road Mineral Provides Update: Guintar -
Margaritas Project, Colombia
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). Best intersections to date are as follows.

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."
