RIVERSIDE MOVES FORWARD WITH 100% OWNERSHIP INTEREST IN THE

THOR COPPER PROJECT, SONORA, MEXICO

June 1, 2017 – Vancouver, BC: Riverside Resources Inc. (“Riverside” or the “Company”)

(TSX-V: RRI), has regained a 100% interest in the Thor Copper Project (the “Project”), as the

Company’s joint -venture partner, a subsidiary of Antofagasta plc (“Antofagasta”), has elected

not to complete the C$5M in exploration expenditure required to earn a 65% interest in the

Project. The Thor Copper Project is located in north -eastern Sonora along the main copper

producing belt of Mexico . Riverside and Antofagasta completed an initial proof-of-concept drill

program to test for a Laramide aged porphyry-intrusive system. The first four (4) drill holes ever

drilled at Thor confirmed the concept, with three of the four drill holes intersecting a large

Laramide-aged porphyry style quartz-sericite-pyrite stockwork system. The initial drill holes did

not return sufficient gold or copper assays for partner Antofagasta to continue , but the limited

drilling that was completed was successful in hitting alteration and providing supp ort for further

exploration.

Riverside will regain a 100% i nterest in the Thor Copper Project with drill permits already in

place, drill cores, maps, data and target areas defined. The Company also owns the 12.4 km2

Ariel Copper-Gold Project, which was w on through the lottery -staking system and is

strategically located 30 km ESE of the La Caridad Cu -Mo porphyry mine. Ariel covers an

extensive zone of hydrothermal alteration, measuring 2.8 km in length by approximately 1.9 km

wide. Riverside owns three qua lity copper porphyry prospects in northern Mexico, and will

explore partnership opportunities to advance the copper portfolio going forward.

Riverside’s President and CEO, John -Mark Staude, stated: “We would like to thank Antofagasta

for the very collabo rative exploration effort at Thor . Riverside now has three copper-gold

projects available for option as a package or individual prospects; all with good road access,

clean ownership, no underlying royalties and prospective exploration targets already defin ed.

We look forward to progressing our Prospect Generation exploration approach with these

properties and welcome partners.”
