RIVERSIDE RESOURCES AND CENTERRA GOLD COMPLETE PITAYA TARGET

DRILLING AT THE GLOR GOLD PROJECT IN SONORA, MEXICO

June 19, 2017 – Vancouver, BC: Riverside Resources Inc. (“Riverside” or the “Company”)

(TSX-V: RRI), has completed an initial nine-hole diamond core drilling program at the 4 km²

Pitaya Target within the 36 km² Glor Gold Project (the “Project”), which is being explored with

funding by partner, Centerra Gold Inc. (“Centerra”). The Project hosts five key target areas and

is located approximately 8 km west of Alamos Gold’s El C hanate Mine in Sonora, Mexico . The

recently completed drill program focused on the Pitaya Target located in the north-eastern sector

of the Project , which had been defined by partner-funded soil geochemistry and induced

polarization geophysical surveys and then further investigated with mechanical trenching and

chip-channel sampling (see Company press releases issued on February 15 and April 17, 2017).

Assay results have now been received for all nine drill-holes, which together total 1,942 metres

in length. The longest hole was 285 metres. Drill -hole GL17-002D yielded the best intersection

of gold mineralization of the campaign: 11.0 metres averaging 0.591 grams gold per tonne (g/t

Au) starting at 122 metres down the in clined drill-hole. The highest gold value included in this

assay interval is 1.415 g/t Au over 1.0 m etre of core . The other eight drill -holes intersected

sporadic thin zones of gold mineralization that generally graded less than 0.4 g/t Au across 1.0

metre, with the best of these intercepts being a 2.0 m etre interval in GL17 -004D that averaged

0.466 g/t Au.

Riverside’s President and CEO, John- Mark Staude, stated : “Given the trench sampling

intervals gave disseminated gold values in the range of 0.5- 1 g/t Au at the Pitaya Target, we are

surprised that this initial drill campaign didn’t manage to replicate these results. We’ve been

mapping and sampling the larger Glor tenement finding numerous areas with gold and remain

positive on the Project’s potential. So far w e’ve developed five target areas and have only

trenched and drilled one . The four additional target areas will be field sampled and worked on

in the coming months to determine if another drill program will be pursued.”

Figure 1 below displays the location of the Pitaya Target in relation to the other four target areas

that remain undrilled at the Glor Project. Figure 2 is an enlargement of the Pitaya Target area

showing the locations of drill -hole collars and surface traces with respect to the trenches that

were excavated and sampled just prior to the commencement of drilling.

Additional Drill Program Details:

The gold assay results for the 9 -hole drilling campaign are in general weaker than the assay

results that were obtained fr om the chip -channel samples collected from the trenches in the

immediate area of the Pitaya drill-holes. A possible explanation for the discrepancy between the

drilling and trench sampling resul ts is that the extensive mineralization sampled on surface

transect in trenches Tr-01 and Tr-02 occurs in a zone of altered andesite that is exposed along an

easterly inclined dip -slope in the local topography . (Drill-hole G17 -002D appears to have

perpendicularly intersected the subsurface down-dip continuation of th is zone of gold

mineralization (see Figure 2) indicating a true thickness of approximately 11 meters.

anomaly, drill holes and trenches completed at the Pitaya Target

There is a spatial relationship between gold and arsenic (As) at the Pitaya Target, where core

samples having gold concentrations greater than 0.3 g/t Au are seen to have As contents of 5,000

ppm and greater. The drill -hole sample containing 1.415 g/t Au showed an As content of

>10,000 ppm As. This feature is similar to other orogenic gold systems in north -western, Sonora

and indicates the district is the type of region that could be fertile for a new gold discovery.

Although the drilling of the Pitaya target area did not produce an economically significant

discovery, much has been improved in the understanding of controls on gold mineralization ,

which are now being applied to the overall Glor Project. Project geologists are in the field

investigating other geochemical survey anomalies on the Project with the objecti ve of refining

existing target areas and defining new high -potential drill targets . Particu lar attention will be

given to the rock and soil geochemistry, structural geology, ground magnetic data and utilizing

induced polarization as a tool to refine the targets. Fieldwork will continue to be funded by

Centerra through the next quarter and, if sufficiently prospective gold targets are generated, a

second round of drilling will possibly be completed before the end of the year.

Qualified Person and QA/QC:

The scientific and technical data contained in this news release pertaining to the Glor Project was

reviewed and prepared under the supervision of Locke Goldsmith, P. Eng., P. Geo., a non-

independent qualified person to Riverside Resour ces who is responsible for ensuring that the

All drill cores were photographed, geologically logged and then sawed in half to provide samples

for gold assaying and multi-element ICP mass spectrometry analysis, which was done by Bureau

Veritas’ laboratories in Hermosillo, Mexico and Vancouver, Canada, respectively. A total of

1,246 core samples were analysed, with individual samples having core lengths of 1.0 m or 3.0

m, depending on the presence or absence of visible hydrothermal alteration. For quality

assurance and control purposes 48 non -mineralized ‘blank’ samples and 83 standard samples

were included with the batches of core samples that were analysed.
