RIVERSIDE RESOURCES SAMPLES UP TO 5.45 G/T GOLD AND ESTABLISHES 5

PRIORITY DRILL TARGETS AT THE CECILIA GOLD PROJECT IN SONORA,

MEXICO

July 25, 2017 – Vancouver, BC: Riverside Resou rces Inc. (“Riverside” or the “Company”)

(TSX-V: RRI), is pleased to announce that the Company has completed the first phase of self-

funded exploration at the Cecilia Gold Project (t he “Project”) located in northeastern Sonora,

Mexico. Riverside is targeting epithermal gold-s ilver mineralization within and beneath a felsic

volcanic flow-dome complex which is similar in age and composition to the dome complexes

that are associated with the la rge La Pitarrilla and San Julia n Ag(-Au)-Pb-Zn deposits found in

the Mexican state of Durango.

Highlights of Riverside’s second batch of sampling results included 8.0 and 9.7 metre wide

zones of gold mineralization at the North Breccia Zone that averaged 3.90 g/t Au and 1.18

g/t Au , respectively. These intervals encompass a to tal of 8 chip-channel samples 1.80 to 3.0

metres in length. About 400 metres southwest of the North Breccia Zone an altered fault

structure was mineralized, with a 3.0 m wide zone showing an average grade of 5.45 g/t Au.

The Company’s exploration program has successfully outlined a numbe r of priority drill targets

and Riverside has now started the application process for drill permitting.

Riverside’s President and CEO, John-Mark Staude, stated : “Riverside acquired the Cecilia

gold Project because our geologis ts view the volcanic complex at the heart of the Project as

being a prime setting for a major epithermal mi neral system, predominantly gold-bearing at

higher levels and possibly more silver rich at lower elevations. The fieldwork we have completed

so far, combined with the compilation and analysis of historical data, further supports this view.

We have at least five high-poten tial gold targets defined at the Project, which are being

permitted for drilling.”

A key component of Riverside’s exploration program was to confirm the existence of multiple

zones of gold-bearing hydrothermal breccia and quartz stockwork veining that had been sampled

decades ago by other groups, including Chesapeake Gold Corp., Cambior Explorations and the

Consejo de Recursos Mine rales, the predecessor to Mexico’s geological survey, Servicio

Geologico Mexicano . (for details, see Project History on th e Company’s website ). Riverside

accomplished this by collecting and analyzing a total of 406 rock samples from the Project’s four

main gold zones, the North Breccia, Central, West and East Zones (see Figure 1 , below).

Bedrock exposures in areas surrounding the four prospects were also sampled with the objective

of expanding the known zones of gold mineraliza tion. The distribution of 1,443 historical rock

samples plus 371 Riverside samples is shown in Figure 1. Clusters of samples with gold

concentrations greater than 0.3 g/t Au clearly define th e above-mentioned gold zones.

Importantly, gold mineralization at Cecilia is seen to be widespread, occurring over an area that

is roughly 1,200 metres by 400 metres, and it is also found over an elevation range of more than

400 metres.

In addition to its rock sampling program, Ri verside’s geologists compiled and reviewed

geological and geochemical data se ts that had been generated ove r a 35-year history of modern

exploration at Cecilia. This data base includes drill-hole logs and core sample analyses for 19

diamond boreholes (3,817.6m), maps and hundreds of rock-channel assays for twenty

underground workings that reportedly date back to the 1940s, as well as multi-element analyses

for 1,979 surface rock samples. A basic statistical analysis of gold assays obtained by Riverside

and two previous companies is shown in Table 1.

Specific drilling targets have now been selected at Cecilia and a work permit application for a

drilling program is being prepared for Mexi co’s environmental agency, SEMARNAT. Such

permits are typically received 2 to 3 months af ter applications are subm itted. The selection of

Riverside’s drill targets was guided by gold assay data for surface and underground rock samples

that were viewed in the contex t of a geological and exploration model of the Cerro Magallanes

volcanic flow-dome complex. This model was deve loped by Riverside’s geologists and is based

on other flow-dome complexes in Mexico where economically important ore systems are found

(eg. La Pitarrilla, San Julian).

Riverside’s planned drill-holes have been design ed to test the North Breccia, Central and East

gold zones using borehole orientati ons that in most cases will be at least 90° to the azimuth

directions of the historic drill-holes, i.e. the planned holes will be directed to the south or

southwest instead of to the northwest. Many of the boreholes drilled in 1995 are interpreted to

have been oriented subparallel to the main mineralized structures, consequently missing their

targets. Existing drill roads, with minor upgrading, will facilitate future drilling.

Some of Riverside’s proposed dr ill-holes are designed to test deeper levels of the volcanic

complex to explore for feeder structures that may contro l large epithermal quartz veins

containing high-grade gold-silver mineralization. Such mineraliz ation was found in boulders

scattered at the entrance s to a few of the old underground wo rkings at the Central Zone (see

press release on June 6, 2017). Select samples of th is type of quartz vein ing yielded gold assays

of 13.9 g/t Au 19.0 g/t Au, 55.0 g/t Au and 133.7 g/t Au, with corresponding silver assays of 20.7

g/t Ag, 335.0 g/t Ag, 288.0 g/t Ag and 87.8 g/t Ag.

Riverside’s President and CEO, John-Mark Staude, added: “Riverside is actively discussing

potential joint-venture partnerships with a nu mber of parties on multiple projects in the

Company’s portfolio. We have several projects with high-quality drill targets and are committed

to securing multiple new partnerships, while also completing a self-funded drill program by the

end of the year. We believe this approach exposes our shareholders to the most catalysts and

discovery upside.”

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

The rock chip samples collected by Riverside's fiel d crew at the Cecilia Pr oject were taken from

bedrock outcroppings on the slopes of the prom inent mount of Cerro Magallanes, with the

majority of individual samples consisting of composites of bedrock fr agments hammer-chipped

from 1.1 to 3.1 metre long intervals across ro ck faces showing evidence of hydrothermal

alteration. A total of 406 rock-chip samples were collected and analyzed by Riverside, 12 of

which consisted of select grab samples of loos e quartz vein rock found on waste-rock dumps of

small underground workings that exist at the core of the Project. Assay re sults for these select

samples are not plotted on the map shown in Fi gure 1. All of Riverside's rock samples were

analyzed at the Hermosillo and Vancouver laborato ries of Bureau Veritas where gold content

was determined by fire assaying with atomic adsorption finish and ICP-mass spectrometry was

used to analyze for 45 other elements. For qual ity control purposes, 14 standard samples and 7

'blank' samples were included with the batch of 406 field samples from the Project.
