Scout RC Drilling Extends Gold Mineralization to the West, Diamond Drilling Commences
Toronto, Ontario--(Newsfile Corp. - March 2, 2022) - Royal Road Minerals Limited (TSXV: RYR) ("Royal Road" or the "Company") is pleased to provide an exploration update from its Caribe gold discovery in northeastern Nicaragua.
The Caribe project forms a part of the Company's Strategic-Alliance agreement (see press release; September 6, 2017) with Hemco Mineros Nicaragua ("Hemco" a subsidiary of Mineros S.A., TSX:MSA) and is located in the highly prospective "Golden Triangle" of northeastern Nicaragua. Royal Road Minerals is operator of the Strategic Alliance.
Royal Road's exploration team discovered the Caribe project during reconnaissance exploration in February of 2018. Outcrop at Caribe is concealed under soil and saprolite cover and there is no previous record of mining or mineralization in the area. In 2019, Royal Road and Hemco completed an initial 4-hole, exploratory drilling program at Caribe which returned promising results for gold. A follow-up diamond drilling program commenced at the project during August of 2020 and has returned encouraging initial results including CB-DDH-025, 207.45 meters at 1.1 grams per tonne, CB-DDH-016, 100.45 meters at 1.0 gram per tonne; CB-DDH-017, 90 meters at 1.0 gram per tonne and CB-DDH-015, 63 meters at 1.0 gram per tonne gold (see Press Releases November 10, 2020, February 11, 2021, March 17, 2021, September 1, 2021 and Table 1).
Drilling at Caribe has revealed that in some cases, soil and laterite cover extends to depths in excess of 30 meters, concealing important geological and geochemical information and frustrating efforts to interpret geometry and predict extensions to known gold mineralization. Consequently, in September 2021, the Company took the decision to suspend diamond drilling and commence a program of grid-based scout reverse-circulation drilling at the project. The program utilizes a small, low-impact, man-portable reverse-circulation (RC) drilling rig which drills through soil and saprolite cover down to the first 2-3 meters of weathered rock where a sample is taken for analysis. 210 vertical scout-RC holes averaging approximately 18m in depth have so far been completed (see Figure 1).

Results received to-date imply that the gold mineralizing system remains open to the west and southwest and portable XRF analyses[1] suggest a broad and significant copper anomaly towards the east (Figure 1).
Gold at Caribe is hosted in coarse pyroclastic rocks and associated with multi-phase stockwork and hydrothermal breccia events within a broad low-temperature sericite halo and in later-stage sulfide-rich hydrothermal breccia bodies with a matrix composed of pyrite, chalcopyrite and molybdenite. Previous interpretations had assumed a fault- limited control to the western extent of gold mineralization at Caribe, however this new scout-RC data clearly implies continuity across the fault and/or some element of fault control to gold mineralization at the project.
Diamond drilling has now recommenced at the project and further infill and extensions to the scout-RC program are planned.

"We are pleased that the scout-RC program is returning the information we had hoped for and revealing further potential for gold and possibly copper mineralization at Caribe" said Tim Coughlin, Royal Road's President and CEO "The influence of such deep saprolite cover and the inability to confidently predict geometry and continuity, made locating diamond drill holes something of a challenge towards the latter end of last years campaign. With these new scout-RC results, as further results are received and as we extend and infill the scout-RC grid, we will be better able to understand controls and guide the location of our diamond drill holes".

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.

Quality Assurance and Quality Control:
Diamond drill core is cut in half over 1-meter downhole intervals using a core saw. Samples are prepared and assayed by independent and ISO accredited laboratories of Bureau Veritas Minerals (BVM) and their local subsidiaries. Bagged 1-meter samples are collected from site and delivered to BVM sample preparation laboratories in Managua. Samples are prepared using the BVM codes PRP70-250 plus PUL85, where samples are crushed to 70% less than two millimeters, a riffle split of 250 grams is collected and then pulverized to better than 85 per cent passing 75 microns. Prepared sample pulps are then sent for analysis to BVM labs in Vancouver Canada. Gold is analyzed by fire assay with an atomic absorption finish and a measurement range of 0.005 to 10 ppm. Samples over 10-ppm gold are re-analyzed by fire assay with a gravimetric finish. Multielement concentrations are analyzed by four-acid digestion and inductively coupled plasma mass spectrometer. Samples over 10,000ppm Cu, Zn, Pb or Mn and 200 ppm W, are re-analyzed with four acid digestion and Inductively Coupled Plasma Emission Spectrometer (ICP-ES). Commercially prepared standards (gold-copper pulps), blanks (pulps and coarse chips) and field duplicates are inserted into the sample stream by Royal Road Minerals for a total of 15% QA/QC to ensure sample precision. In the case of duplicate analyses of a sample, the average of both analyses is used as the final reported value. Unless otherwise stated, gold grades are not capped for calculation of length-weighted averages.
RC chip samples are taken every meter after having entered 2-3 meters within the saprock-fresh rock boundary. Samples are collected from the drilling site and dried at the core yard. Where dry sample weights exceed 4.5Kg they are split. Bagged 1-meter samples are collected from site and delivered to the BVM sample preparation laboratory in Managua. Samples are prepared using BVM codes PRP70-250 plus PULSW where a riffle split of 250 grams is collected and then pulverized to better than 85 per cent passing 75 microns. Sample pulps are then sent for analysis to BVM labs in Vancouver Canada. Gold is analyzed by fire assay with an atomic absorption finish and a measurement range of 0.005 to 10 ppm. Samples over 10 ppm gold are re-analyzed by fire assay with a gravimetric finish. Multielement concentrations are analyzed by four-acid digestion and inductively coupled plasma mass spectrometer. Samples over 10,000ppm Cu, Zn, Pb or Mn and 200 ppm W, are re-analyzed with four acid digestion and Inductively Coupled Plasma Emission Spectrometer (ICP-ES).
