Toronto, Ontario--(Newsfile Corp. - January 11, 2016) - Royal Road Minerals Ltd. (TSXV: RYR) ("Royal Road Minerals" or the "Company"), a gold focused mineral exploration and development company, is pleased to announce results from the first eleven saw-cut channel samples from underground workings at the La Golondrina gold mine in Colombia.
La Golondrina is a currently small-scale underground gold mining operation located in the La Llanada gold mining district of Nariño province in southern Colombia. La Golondrina comprises multiple levels of horizontal underground mine development which have accessed surface exposures of dominantly shallow-dipping high-grade quartz-veins (see Figure 1) and vein zones over a known vertical extent of 400 meters and over an aerial extent of approximately 600 by 800 meters (see Figures 2 and 3). Mining at La Golondrina commenced during the early 1980's and has been focused only on those quartz veins that are accessible and exposed (see Figure 2). Much of the La Golondrina license area is concealed under recent volcanic ash, colluvium and soil. In 2011 AngloGold Ashanti conducted geological mapping, rock-chip sampling, IP-geophysics and ground magnetics over the project area. Mineralization at La Golondrina is part of an Eocene age intrusion-related gold system hosted in a Cretaceous age metasomatized (hornfels) marine sedimentary sequence. The Company has an option to earn a 100% undivided interest in the project under the terms outlined below (see Press Release October 7th 2015). There has been no drilling conducted at La Golondrina. Management of the Company believes that there is an opportunity to define a significant high-grade plus million ounce resource at the project and to rationalize, modernize and expand the current operations.
The Company is currently conducting saw-cut channel sampling on two active underground mining levels at La Golondrina. The aim of this sampling is to confirm the high-grade nature of vein-hosted gold mineralization and to test vein zones and vein stockwork zones in the host-rock outside of and adjacent to the main vein bodies. The results from the first eleven saw-cut channel samples from the El Alacran and El Ingenio adits (See Figures 2 and 3) have now been returned (see Table 1). Underground quartz vein samples returned an average of 41.5 g/t gold over 0.3 meters with the best result being 106.5 g/t gold over 0.7 meters and gold mineralized veinlet stockwork zones hosted in hornfels have returned up to 41.8 g/t gold over 1 meter. Wall rock material including hornfels has been to shown to carry gold mineralization where it is penetrated by quartz veins and veinlets or is silicified. Metallic screen analyses reveal that on average 94% of gold reports to the plus 150# (>.125mm) size fraction.
Dr. Tim Coughlin, President and Chief Executive Officer of the Company, stated "This is an encouraging first batch of sample results which confirms the high-grade nature of quartz vein hosted gold mineralization at La Golondrina, proves that gold mineralization there extends beyond the boundaries of the intrusive host-rock into adjacent hornfels and shows that gold is generally coarse and thus probably amenable to commercial-scale recovery by gravimetric methods. Further saw-cut channel sampling is underway from active underground development and we are trying to access some of the older workings. Once complete, the analytical results from these channel samples will be very useful for resource calculations and for statistical analysis of drill results which can prove problematic for high-grade gold mineralization. Our key question as far as the vein-style gold mineralization at La Golondrina is; what is the lateral extent and stack density, or vertical frequency of quartz veining? Mapping work shows that veins, where accessible and exposed, extend over a total vertical interval of at-least 400 meters but only drilling will reveal the answer to their lateral extent and stack density. As far as bulk tonnage targets go, it is very encouraging to see that gold mineralization extends into the adjacent hornfels as the heterogeneous physical and chemical nature of this rock may hide some favourable host settings that can only be revealed by geophysics. We are currently working through IP-geophysical and ground magnetic data which has already revealed some interesting possible bulk tonnage targets considered worthy of drill testing."

The information in this news release was compiled, reviewed and verified by Dr. Tim Coughlin, BSc (Geology), MSc (Exploration and Mining), PhD (Structural Geology), FAusIMM, President and CEO of Royal Road Minerals Ltd. and a qualified person as defined by National Instrument 43-101. Royal Road Minerals employees are instructed to follow standard operating and quality assurance procedures intended to ensure that all sampling techniques and sample results meet international reporting standards. Rock faces for underground channel sampling are first washed with a high-pressure hose and then channel sample locations are clearly marked and numbered using spray paint. Channels are cut with dual or single blade electric rock-saws to a depth of 3-5cm and over a channel width of 10cm. Individual sample lengths do not exceed 1 meter. Individual quartz veins and in some cases vein zones may be cut longitudinally along the vein wall to ensure the collection of a statistically significant amount of vein material. Channel material is extracted using a hammer and chisel and bagged for analysis on location. All assay work for released results is carried out by internationally certified Actalabs in Colombia and Canada. All samples are analyzed by fire assay for gold and high-grade samples may be assayed by gravimetric fire assay and metallic screen (150#). Multielement analysis by ICP-MS is also conducted.
