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 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.
