Toronto, Ontario--(Newsfile Corp. - December 14, 2021) - Royal Road Minerals Limited (
TSXV: RYR
)
("Royal Road" or the "Company") is pleased to announce results from the first three drill holes of its
current drilling program at the Guintär copper-gold project in Antioquia Department, Colombia.
The Guintär project is part of the Guintär-Niverengo and Margaritas (GNM) project area which comprises
the two contiguous Guintär, and Niverengo concession contracts and the neighboring Margaritas
concession contract located in the Middle Cauca Valley, approximately 50 Km west of Medellin in
Antioquia Department, Colombia. The titles were acquired through the Company's purchase of Northern
Colombia Holdings Limited, an affiliate of AngloGold Ashanti Limited (see Press Release May 31,
2019). The GNM area is subject to a Strategic Alliance Agreement between the Company and Mineros
S.A. ("Mineros
TSX: MSA
; see Press Release March 2, 2020). Under the terms of the Agreement,
Mineros currently own a 25% interest in the GNM project area and may acquire a further 25% (up to a
total 50%) interest by providing the balance of a further USD $1.5M in exploration funding. Royal Road
Minerals are operators of the Strategic Alliance.
The Company has received results from the first three diamond drill holes at its Guintär project, details
are presented in
Table 1
and significant intersections are as follows:
GUI-DD-011
17.9 meters at 0.9 grams per tonne gold
GUI-DD-012
303.7 meters at 1.1 grams per tonne gold
equivalent
[1]
(to end of hole)
(0.7 grams per tonne gold, 4.3 grams per tonne
silver and 0.22% copper)
Including (from 143.0 meters) 62.0 meters at 2.1
grams per tonne gold, 12.4 grams per tonne
silver and 0.62% copper
GUI-DD-013
126.0 meters at 1.4 grams per tonne gold
equivalent
(0.8 grams per tonne gold, 5.5 grams per tonne
silver and 0.34% copper)
Including (from 120.0 meters) 55.0 meters at 1.5
grams per tonne gold, 10.8 grams per tonne
silver and 0.60% copper; and
44.0 meters at 1.1 grams per tonne gold
(Not true width and the company does not have sufficient information to make a determination of the true
widths of the drill hole intersections)

*NOT TRUE WIDTH
DOWN HOLE CUT-OFF 0.2 g/t gold only
MAXIMUM INTERNAL DILUTION -10 Meters
Drill hole GUI-DD-011 intersected gold mineralized basement rocks belonging to the early-Cretaceous
Barroso Formation with low-grade gold (entire drill hole returned 0.2 grams per tonne gold over 400.56
meters) disseminated through the hornfels-altered sequence and higher grade intervals (including 9.8
grams per tonne gold over 1.6 meters) related to lithological contacts and more porous conglomeratic
units.
Drill hole GUI-DD-012 intersected strongly altered porphyritic intrusive rocks at 93 meters downhole
depth (see
Figure 1
). Alteration is characterized by biotite related to quartz-chalcopyrite-pyrrhotite
mineralized stockwork veinlets and albite related to chalcopyrite-pyrrhotite mineralized sheeted veinlets.
Gold, copper and silver are related to both stockwork and sheeted veinlet styles of mineralization. Not
applying a cut off, the entire drill hole returned 320.7 meters at 1.1 grams per tonne gold equivalent from
surface. This intersection is the first indication of significant porphyry-style, copper and gold
mineralization at the Guintär project. Drill hole GUI-DD-013 was located beneath GUI-DD-012 (see
Figure 1
) and intersected the biotite-altered intrusive suite with associated mineralization at a down hole
depth of 118 meters. The entire drill hole returned 588.3 meters at 0.7 grams per tonne gold equivalent.
Deeper gold-only mineralization (44.0 meters at 1.1 grams per tonne gold from 351 meters) may be
related to a more amphibole-rich intrusive suite.
"These are very exciting initial results from our Guintär project," said Tim Coughlin, Royal Road Minerals
President and CEO. "They are the product of some very careful geological work which utilized our
existing geochemical database to provide vectors into a potential source of the ten square kilometers of
alteration and mineralization we observe at surface. Furthermore, coupled with our Margaritas gold
project, located just four kilometers to the southeast of Guintär, it now appears as though we are defining
a new and underexplored copper-gold district in the Middle Cauca region".

Absorption and multi-elements by ICP-AES and ICP-MS after four acid digestion. Stream sediment
samples are sieved to -200 mesh and analyzed for Gold by fire assay and ICP AES and multi-
elements by ICP-AES and ICP-MS after aqua regia digestion. Analytical performance is monitored by
means of certified reference materials (CRMs), coarse blanks, coarse and pulp duplicate samples.
Surface samples have been prepared in ALS Chemex preparation lab in Colombia and analyses
have been completed in ALS Chemex Lima.
