New mines for a new world

Royal Road Minerals


The Guintar-Niverengo-Margaritas (GNM) project is located in the Anza district, 50 Km west of Medellin, in the northern portion of Colombia’s prolific Middle Cauca belt.

Rocks within the GNM region are predominantly late Cretaceous-Paleocene age, deep marine meta-sediments and mafic marine volcanic rocks which have been intruded by dioritic to dacitic stocks of Upper Miocene age (Tornonian-Messinian).

Located to the north of the project, the Guintar-Niverengo area is represented by an intermediate to strongly hornfelsed sedimentary sequence with magnetite and biotite forming part of the metasomatic assemblage. Accompanied with this is the formation of gold (±copper) bearing skarns with high temperature calc-silicate minerals and quartz, which have been overprinted by gold bearing epithermal veins.

Mineralization at Guintar (west of Niverengo) is best represented by the El Aleman mine which is a licensed artisanal operation located on the edge of the title. At El Aleman, thin east-west oriented and steeply dipping quartz-sulfide (pyrrhotite, pyrite, marcasite) veinlets host gold mineralization averaging approximately 20g/t across individual vein thicknesses of up to about 10cm and over about a 50m zone width and 1.5km strike length.

To the south of the project, the geology and mineralization of the Margaritas area differs significantly compared to its northern counterpart (i.e. Guintar-Niverengo). Skarn mineralization is absent and gold mineralization is instead characterised by hydrothermal breccias carrying significant gold but also silver grades (recent sampling by the Royal Road technical team returned gold and silver values of >1 g/t and >100 g/t respectively). Similar to Guintar-Niverengo, epithermal veins remain present in the area with the most anomalous historical samples by AngloGold Ashanti returning 34.9 g/t gold and 2080 g/t silver.

A 10-hole, 4184m scout drilling program was conducted at Guintar by AngloGold Ashanti in 2015. Drilling intersected gold mineralized quartz-veins similar to those at El Alemán in addition to low grade Skarn mineralization but failed to identify any broad zones of economic value. Best results were 28m at 0.9 g/t gold and 12m at 1.8 g/t gold.

In 2016 and 2017 AngloGold Ashanti’s interest shifted to the Niverengo area, some 1.5km east and along-strike of the Aleman mine but across a major north-south oriented reverse fault and into a younger sequence located possibly structurally above the Aleman mineralized system. Magnetics, IP-geophysics, soil and rock-chip geochemistry identified a 2000m by 800m wide target, interpreted to represent the low-sulfidation reflection of an underlying Aleman vein-system.

A 6-hole, 1479 meter scout drilling program was conducted at Niverengo. Best intersections were from drill holes three and four which were drilled from the same drill pad at 180-degrees from each other in an area of deep soil cover and no outcrop. Drill hole 3 intersected 36m at 1.2g/t gold from surface and drill hole 4 intersected 10m at 1.6g/t gold and 88m at 0.9g/t gold. Projected to surface, the two drill holes identified a gold mineralized zone of approximately 100m width which remains open to the east and west. Gold mineralization is related with skarn alteration and pyrrhotite-filled fractures and veins

On September 19th and December 4th of 2019, The Regional Autonomous Corporation of Antioquia - Corantioquia, granted Royal Road Minerals the extension of the current water collection permit and two industrial wastewater discharge permits, necessary to advance in the execution of the exploration program in its mining titles IJN-14221 (Guintar) and IJN-11331 (Niverengo).

In Q1 2020, the Company closed a joint-venture- option agreement with Mineros S.A. to advance the GNM Project. The agreement Under the terms of the agreement Mineros may earn 50% of the project by spending USD$2.5 million in exploration expenditures. Royal Road is operator of the joint-venture

Both companies carried out the evaluation of the project's potential and determined an exploration program, prioritizing bulk tonnage targets. The initial part of this program comprises drilling, primarily on geophysical targets in a 4 square kilometer area defined by soil geochemistry on the western edge of the Niverengo title area.

Royal Road is focused on the discovery of “Tier 1” gold and copper mines where they are most likely and most needed

We are the largest title and title application holder in Colombia with quality gold and copper exploration projects located in two main regions; The Northern Block, encompassing the prolific Middle Cauca belt, and the Southern Block, incorporating the most prospective and under-explored regions of the Andes.

Operating under the structure of a 50-50 strategic alliance with HEMCO Mineros Nicaragua, we are the exploration largest license holder in the Country. Currently, the exploration work in Nicaragua is focused on drill-testing three drill-permitted gold and copper-gold projects.
