Riverside Provides Results and Exploration Updates from Two Alliance-Funded Properties in Mexico

Riverside Provides Results and Exploration Updates from Two Alliance-Funded 
Properties in Mexico 
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 02/25/13 -- Riverside
Resources Inc. ("Riverside" or the "Company") (TSX
exploration results and program updates for recent work completed at
the Company's Naranjo and Huacana projects in Mexico. Both projects
are being advanced under the iron-oxide copper gold (IOCG) Strategic
Alliance with partner Cliffs Natural Resources Exploration Inc., a
wholly-owned subsidiary of Cliffs Natural Resources Inc.
(NYSE:CLF)(Paris:CLF) ("Cliffs"). Riverside is currently managing a
fully funded USD$450,000 work program now underway at the Huacana
Project. The exploration work program consists of geologic mapping
and rock-chip sampling, soil and stream-sediment sampling,
re-examination of previous drill core, analytical studies, and an
aeromagnetic-radiometric survey. Soil and stream-sediment sampling
data have been received and are being interpreted; initial results
are confirming and expanding the previously known positive results
for a porphyry copper system. 
The aeromagnetic-radiometric geophysical survey was recently
completed at Huacana and data is being processed and interpreted.
Geologic mapping is now underway. The exploration work program at the
Huacana Project is intended to obtain detailed information to help
refine the upcoming drill targeting to fill in and extend from
previous drilling on the project with the hope of discovering the
next major porphyry copper deposit in the Michoacan copper belt. 
The drilling of three magnetic high anomalies was completed by
Riverside at the Naranjo Project in Jalisco, Mexico, an iron-oxide
copper gold (IOCG) target. The drill results intersected formational
magnetite and did not discover a large iron body as had been hoped,
following positive indications from airborne geophysics. With this
target successfully tested, the Alliance has shifted focus to the
more advanced Huacana Project. 
The Huacana Project is located in the known porphyry copper district
of Inguaran, Michoacan, in the southwestern Mexico copper-gold belt,
host to other notable porphyry copper projects including the La Verde
project being developed by Catalyst Copper and Teck, located 45 km
northwest of Huacana. The Huacana Project was recently acquired by
Riverside through an Option Agreement with Rome Resources Ltd.
(Agreement details below), and is now being advanced under the IOCG
Exploration Alliance with Cliffs.  
John-Mark Staude, President and CEO, stated, "We are pleased to have
completed drilling at Naranjo, and although disappointed not to make
a new grassroots discovery, we were able to give our stakeholders a
shot at a big success while limiting the share dilution and direct
costs through our Prospect Generator business model." Staude added,
"We now look forward to moving ahead rapidly with the Huacana Project
where we see significant upside for Riverside shareholders and
advance towards drill testing in a historically productive copper
district of Mexico."  
Agreement Details 
In March of 2012, Riverside Resources Inc. entered into an Option
Agreement with Rome Resources Ltd. ("Rome") (as announced by Rome on
March 21, 2012 and amended on October 15, 2012) for the Inguaran
Project (now called "Huacana"), located in Michoacan, Mexico. Under
the Agreement, Riverside can earn a 75% interest in the Huacana
Project by incurring an aggregate $5M in exploration expenditures on
the property by July 2, 2017. If Rome's interest is diluted to less
than 10%, Rome's interest will be converted to a 1.5% NSR, of which
0.5% can be purchased for $1,000,000.
