Royal Road Reports New Ground Geophysical Results from the Caribe Gold Discovery; 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 Colombia's Grupo Mineros S.A. MINEROS:CB) and is located in the highly prospective Golden Triangle of northeastern Nicaragua, approximately 16 kilometers to the southeast of the Company's Luna Roja Gold Skarn project (see press release; October 1, 2019). Royal Road Minerals is operator of the Strategic Alliance.
Royal Road's exploration team discovered the Caribe prospect during reconnaissance follow-up of an airborne geophysical anomaly in February of 2018. Topographically the prospect area is planar, outcrop is non-existent and there is no previous record of mineralization in the area. Initial grab sampling of strongly weathered float material returned anomalous gold with associated anomalous values in molybdenum. Follow-up deep auger soil sampling was then conducted using a 3-meter long hand-auger to access the deep residual soil horizon located below organic and saprolitic layers. Soil-sampling identified a strongly anomalous area of gold geochemistry (see press release; May 15, 2018) of 600 by 400 meters in area. Additionally, 18 1 meter square and 2 to 3 meter deep shafts were dug in order to expose bed-rock, assist mapping and collect channel and grab rock-chip samples. The highest result from grab rock-chip samples collected from these shafts was 3.5 grams per tonne gold (range 0.01 to 3.54 grams per tonne gold; note grab samples are selective samples and are not necessarily representative of the mineralization hosted on the property).
In August and September of 2019, Royal Road and Hemco completed an initial 4-hole, 413 meter, exploratory drilling program at Caribe (see press release October 7, 2019); all drill holes intersected gold with significant intersections including:
CB-DDH-001 28m at 1.1 g/t gold
CB-DDH-002 14m at 1.0 g/t gold
CB-DDH-004 18m at 1.0 g/t gold
Drill holes CB-DDH-003 and CB-DDH-004 ended in gold grade, with the last samples returning 2.1 and 2.3 grams per tonne gold respectively.
The lack of outcrop at Caribe means the Company is relying on petrographic observations from drill core to interpret the style of gold mineralization and results from deep auger sampling, hand dug pits and geophysics to target extensions and potential bulk-tonnage drilling objectives. Drill core petrography has revealed that host rocks to gold mineralization at Caribe are predominantly silica and sericite altered brecciated porphyritic rocks of dacitic to andesitic composition and gold is hosted for the most part in micro-veinlets comprised of quartz, carbonate and adularia. Gold is associated with molybdenite, covellite, chalcopyrite and bornite. These observations suggest a porphyry-epithermal style of gold mineralization at Caribe and may be interpreted to imply that initial drilling is located on the outlying alteration of a nearby porphyry gold and/or copper system.

Caribe was initially discovered during reconnaissance follow-up of a discrete, approximately 500 meter diameter, magnetic high anomaly interpreted to represent the possible magnetic core to a porphyry copper and/or gold occurrence (see Figure 1). This anomaly is completely concealed and so surface samples could not be collected at its locality. New ground magnetic data has now confirmed the location of the airborne anomaly (Figure 1) and 3D inversion suggests that it is located between some 100 and 200 meters below surface. The location of auger sampling and scout drilling at Caribe is approximately 2 kilometers to the southwest of this anomaly and is associated with magnetic lows which parallel a strong and persistent gravity high feature over a strike length of some 1.5 kilometers.
"New analysis and interpretation of the drill core at Caribe is implying a porphyry to epithermal mineralizing environment which is in keeping with our initial interpretation of the airborne geophysics and the main driving factor behind our exploration of the area in early 2018" said Tim Coughlin, Royal Road's President and CEO "The new geophysical information has confirmed target criteria, implied bulk tonnage potential and identified drilling objectives not only in the immediate vicinity of our 2019 scout drilling, but also and more conceptually, at the magnetic anomaly located some 2 kilometers to the northeast. We plan to drill test these targets this year, following the completion of expansion drilling at the nearby Luna Roja project"

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.
