Toronto, Ontario--(Newsfile Corp. - March 18, 2026) - Royal Road Minerals Limited
(TSXV: RYR)
(OTCQB: RRDMF)
("
Royal Road
" or the "
Company)
is pleased to announce results from the first four
drill holes of its current 2,500 meter diamond drilling program at its 100%-owned Güíntar-Aleman-
Margaritas (
GAM
) gold-copper-silver project in Antioquia Province, Colombia (see Figure 1).

Recent drilling at Güíntar, combined with reprocessing of historical results and ongoing geological
mapping and logging, continues to define a coherent expanding porphyry-skarn system extending from
surface to depths exceeding 450 meters, with characteristics consistent with a bulk-tonnage
underground mining scenario (see Figures 2,3 and 4). All drilling results have been systematically
reprocessed using consistent, mining-constrained parameters, including a 0.25 g/t gold equivalent
[1]
downhole cut-off and a maximum of 10 meters internal dilution. Recalculated significant intersections
and the complete set of drill results and collar locations are summarized in Tables 1 and 2, respectively.

(Not true width and the company does not have sufficient information to determine the true widths of the

Drill hole GUI-DD-028 was designed to confirm the sub-surface continuity of porphyry-style stockwork
mineralization exposed at surface, where channel sampling returned 15.7 meters at 0.9 g/t gold, 9 g/t
silver and 0.5% copper. The hole intersected 18 meters of low-grade (biotite-hornfels) skarn before
passing through a fault and intersecting the down-dip continuation of the stockwork approximately 46
meters beneath the surface exposure, confirming approximately 100 meters of vertical continuity. The
hole was also drilled to test below the fault zone that terminated GUI-DD-013; however, it was similarly
terminated within this structure.
Drill hole GUI-DD-029 was designed to test for porphyry-style mineralization within the interpreted
footwall to the main controlling reverse fault structure, considered to represent a partially inverted
Mesozoic basin margin fault (see Figure 2). The hole did not intersect significant mineralization and
returned an average grade of approximately 0.2 g/t gold equivalent. This level of mineralization is
consistent with background values observed in biotite hornfels developed peripheral to the main
porphyry and skarn system at Güíntar.

Drill holes GUI-DD-030 and GUI-DD-031 were designed to test the subsurface continuation of skarn-
hosted vein-stockwork mineralization exposed at surface, where channel sampling returned 24.2 meters
at 0.9 g/t gold, 16.2 g/t silver and 0.3% copper (see Figure 4). Both holes intersected broad and
continuous zones of skarn-hosted mineralization, with GUI-DD-031 returning continuous mineralization
from surface to end-of-hole over 193.7 meters. Mineralization remains open at depth.

Results are pending for drill hole GUI-DD-032, which was designed to test the transition between skarn
and porphyry mineralization, and for drill holes CHU-DD-001 and CHU-DD-002, which were drilled within
the newly granted Chuscalita title (see press release January 12, 2026) to test the eastern continuation
of porphyry-style mineralization and a discrete deep magnetic target east of the Aleman vein system,
respectively.
"These drill results, combined with the reprocessing of historical data using mining-constrained cut-offs
and a reinterpretation of the geology, have significantly improved our understanding of the scale and
geometry of mineralization at Güíntar," said Dr Tim Coughlin, President and CEO of Royal Road
Minerals. "We are now defining a porphyry-skarn system extending from surface over an area exceeding
two square kilometers and to depths of more than 500 meters, with later steeply dipping, high-grade
quartz-carbonate veins enhancing the overall grade profile. This combination of broad, continuous
mineralization and higher-grade overprinting structures is consistent with a bulk-tonnage underground
mining scenario of meaningful scale. Importantly, multiple drill holes remain open in gold and copper
mineralization at depth, and recent drilling has identified at least one concealed corridor extending east-
northeast from Güíntar toward the Niverengo target, which we consider highly prospective and a priority
for follow-up work. Future work will focus on testing this corridor and assessing its potential to host
additional mineralization. With three drill holes still to be reported and drilling set to commence shortly at
the undrilled Margaritas target, we believe the broader GAM system continues to offer significant
upside."
