Riverside and Alliance Partner, Antofagasta, Acquire Option to Earn 80 Percent Interest In the Swift Katie Property, British ...

Riverside Resources Inc. ("Riverside" or the "Company") (TSX
VENTURE:RRI)(PINKSHEETS:RVSDF)(FRANKFURT:R99), is pleased to announce that
Riverside Resources (BC) Inc., a wholly owned subsidiary of Riverside, has
signed a Letter of Agreement with Valterra Resource Corporation ("Valterra"),
for the exclusive right and option to acquire an undivided 80% interest in the
Swift Katie Property (the "Property"). This agreement will be undertaken by the
Riverside Exploration Alliance with a wholly owned subsidiary of Antofagasta plc
("Antofagasta"). Swift Katie is an 80km2 advanced copper-gold-silver porphyry
property located seven kilometres southwest of the town of Salmo, BC, in the
Nelson Mining District. The Property has more than 70 drill holes (approx.
20,000 metres), completed between 1987 and 2008, into a system that currently
measures approximately 1,900 metres of strike length by 900 metres width and 600
metres depth with several directions remaining open for further exploration
upside. (See Project Details below for more information)


In consideration for paying the $40,940 outstanding Advanced Mininum Royalty
("AMR") payment owed to the original owner by Valterra, Riverside (BC) and its
alliance partner (the "Alliance") will be granted a six (6) month due diligence
period to further evaluate the Property. Upon the completion of the due
diligence period, if the Alliance decides to proceed with the Option, it can
acquire an 80% interest in the Property by incurring the following exploration
expenditures as outlined in the table below:




----------------------------------------------------------------------------
                                                                    Property
                                                                Expenditures
Year                                                            (Cumulative)
----------------------------------------------------------------------------
On or before the 1st anniversary of Due Diligence Expiry Date    $   350,000
----------------------------------------------------------------------------
On or before the 2nd anniversary of Due Diligence Expiry Date    $ 1,000,000
----------------------------------------------------------------------------
On or before the 3rd anniversary of Due Diligence Expiry Date    $ 2,500,000
----------------------------------------------------------------------------
On or before the 4th anniversary of Due Diligence Expiry Date    $ 5,000,000
----------------------------------------------------------------------------



Once property expenditures of at least $5,000,000 have been incurred, the Option
will be exercised in full with an undivided 80% interest earned by the Alliance.


President and CEO of Riverside Resources, John-Mark Staude, commented: "We are
excited by the exploration upside at the already established Swift Katie
porphyry copper project. This project adds significantly to our growing copper
porphyry portfolio in BC and we look forward to getting to work and unlocking
further value at Swift Katie for years to come."


Additional Agreement Details: 

In addition to incurring $5,000,000 in exploration expenditures over four (4)
years, the Alliance has agreed to assume the future AMR payments to the original
private ownership group that optioned the Swift Katie property to Valterra. The
AMR payments are to be made on June 30, 2014, December 31, 2014 and annually on
December 31 on each year thereafter. The amount of each AMR payment is $50,000,
adjusted annually in accordance with the Canadian Consumer Price Index with a
base date of December 31, 2006. AMR payments are deductible from future payments
of net smelter returns. 


The original option agreement with the underlying party also provides for a 3%
Net Smelter Return (NSR) royalty. At any time, the Alliance can purchase
two-thirds (2%) of this NSR for $3,000,000.


Riverside and Valterra confirm their mutual intention to conclude and execute
the Definitive Agreement on or before the date that is 45 days from the Due
Diligence Expiry Date, provided however that if the parties do not execute the
Definitive Agreement by such date this letter agreement will remain binding on
the parties and will continue to govern their relationship and operations on the
Property.


Joint Venture: 

Upon the exercise of the Option, Valterra and the Alliance shall be deemed to
have formed a joint venture in which the Valterra shall hold an initial 20%
interest and the Alliance shall hold an initial 80% interest (the "Joint
Venture"). The formal agreement governing the Joint Venture, shall provide that
in the event that Valterra's interest in the Joint Venture is reduced to less
than 10%, Valterra will be deemed to have conveyed its interest to the other
party in consideration of the right to receive a 2% NSR, which can be purchased
by the other party at any time prior to the commencement of commercial
production for $2,000,000. 


About the Swift Katie Property:  

The Property is underlain by the prolific Quesnel Terrane, and covers over 80km2
within a geologically favourable and metallogenically highly endowed area of
British Columbia that historically has hosted several important mining camps.
Three mineral showings are located within the property and for many years were
explored separately in claims with different ownership; the claims were
amalgamated into a single property for the first time under Valterra. There have
been numerous geological, geochemical and geophysical surveys completed on the
property with some of the most significant work funded by subsidiaries of
Noranda and Falconbridge in the 1980s-90s, and by Valterra Resources in
2007-2008. These programs identified several exploration targets, with the most
advanced prospect being the Katie deposit, an alkalic copper-gold porphyry
deposit which has been tested by 72 shallow drillholes to date and remains open
in several directions. Historic drilling at the Katie occurrence covers an
approximately 2km x 1km area with several untested soil, IP, magnetic and
resistivity anomalies in close proximity to known mineralization.  


The property covers an 11km by 3km trend - highlighted by the recent DIGHEM
EM-Magnetic airborne geophysical survey - that remains virtually unexplored
(outside of the Katie occurrence) for copper-porphyry targets to date and
represents significant exploration upside and potential for new discoveries. The
Property is located in an infrastructure-rich area of southern BC (roads, rail,
power, and proximity to the Trail smelter), where a milder climate allows for a
long field season, extensive road networks allow for low-cost exploration, and
is situated in a favourable region of the province that has a strong community
of knowledgeable and experienced people on which to draw.
