Royal Road Minerals Announce Results of New Saw-Cut Channel Sampling from Its Piedra Iman Copper-Gold Project; Nicaragua
To view an enhanced version of Table 1, please visit:
The Piedra Imán concession area is located in Chinandega District, 200km northwest of Managua via the Pan American Highway and 30km north of B2 Gold's El Limon Mine (Figure 1). The concession extends over approximately 8000Ha and is in force for a further 20 years. Royal Road acquired 100% of Piedra Imán through its acquisition of Caza Gold Corp. in May 2017 (see press release May 23, 2017).

Piedra Imán is a copper and gold project which shares many geological similarities with "cordilleran-style" Iron Oxide Copper Gold (IOCG) systems such as those which occur in Chile and Peru. Detailed geological controls remain unclear at Piedra Imán and a mapping program is currently underway, but observations to-date indicate that copper mineralization (malachite, chalcopyrite and bornite) occurs in steeply dipping veinlets and vein-stockworks oriented at a high-angle to gently tilted layering (see Figure 2). Gold is associated with molybdenite in an intrusive rock which appears to be located subjacent to the copper mineralization. Alteration related with copper and gold mineralization at Piedra Imán is characterized by magnetite-hematite-actinolite and albite.

The Piedra Imán project was initially explored in the early 1970's by Noranda Inc. ("Noranda"). Noranda's work included the drilling of 17 shallow diamond drill holes and the development of one exploration adit. Noranda's drilling and underground sampling intersected significant widths of copper mineralization including DDH-851 (36.6 meters at 1.13% Copper), DDH-876 (14.8 meters at 1.65% Copper), DDH-846 (14.3 meters at 1.42% Copper) and DDH-818 (9.1 meters at 1.50% Copper). Samples were only sporadically assayed for gold, but drilling results included one interval of 3.6 meters at 6.3 g/t gold. These results were provided in analogue format, are historic in nature and have not been verified by a qualified person. Historic maps indicate that the exploration adit intersected gold and copper along its strike length with gold only mineralization dominating the southwestern end of the adit and combined copper and gold mineralization dominating the northeastern extent of the adit (see Figure 4). There are no reports available to verify the style of adit sampling or to confirm the underground grades labelled on historic maps. Noranda abandoned the project due to the onset of hostilities related with the Sandinista revolution in 1978.

In order to assess the continuity and local extent of copper and gold mineralization at Piedra Imán, horizontal channels were cut across exposed rock faces with a rock saw to an average depth of approximately 3cm and to an average width of approximately 10cm (see Figure 3). A total of 9 channels were cut and sampled on 1 meter intervals over a total strike distance of approximately 400m (see Figure 4). Results are presented in Table 1. Best results are:
- Channel 4 - 20 meters at 1.10% copper and 5 meters at 0.95% Copper
- Channel 8 - 8 meters at 1.05% copper and 1.13 grams per tonne gold
- Channel 7 - 5 meters at 0.28% copper and 2.50 grams per tonne gold
- Channel 2 - 9 meters at 0.70% copper
- Channel 5 - 6 meters at 0.87% copper
Highest individual results for copper and gold were 1 meter at 2.69% and 1 meter at 7.5 grams per tonne respectively.
The Company has recently submitted application for a drilling permit at Piedra Imán and, if successful, intends to commence drilling at the project in either Q3 or Q4 of this year.
"The results of our limited work to-date at Piedra Imán coupled with these encouraging saw-cut channel results suggest we are dealing with a style of copper and gold mineralization which until now has not been recognized in Nicaragua" said Dr Tim Coughlin, Royal Road's President and CEO. "Soil geochemistry indicates that the mineralized system remains open to the north and southwest and our ongoing geological work will assist us in confirming our IOCG model and in outlining the principal controls on the distribution of gold and copper at the project. We plan to complete some ground geophysics before the end of Q3 and look forward to drill testing the project soon after that".

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 saw-cut channel sampling are first cleaned 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. 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 Bureau Veritas Mineral Laboratories in Nicaragua and Canada. All samples are analyzed by fire assay for gold with an AAS finish and 4-acid digest ICP-ES for multielements.
