Riverside Resources Inc. ("Riverside" or the "Company") (TSX
VENTURE:RRI)(PINKSHEETS:RVSDF)(FRANKFURT:R99) is pleased to announce that new
partner, Morro Bay Resources Ltd. ("Morro Bay"), has completed its qualifying
transaction whereby it has acquired from Sierra Madre Developments Inc. ("Sierra
Madre") an option to earn an initial 51% and up to 65% interest in Riverside's
Penoles Project (the "Transaction"). As a result of the Transaction, Riverside
has received 3,705,974 Morro Bay common shares and 1,852,987 Morro Bay warrants.
Morro Bay will also fund a minimum of $750,000 in exploration and drilling at
the Penoles Project that will aim to build on last year's results at the
historic Jesus Maria silver mine area. Further information can be found in the
Transaction Details section below. 


Riverside's President and CEO, John-Mark Staude, commented: "We are very pleased
with the speed with which this transaction closed and look forward to final
preparations and planning for upcoming drilling at the Penoles Project. There
are several highly prospective targets in addition to the known Capitan, Jesus
Maria and San Rafael zones, and we look forward to unlocking some of this
potential in the weeks and months ahead."


In addition to the $750,000 in exploration expenditures, remaining requirements
for Morro Bay to earn an initial 51% interest in the Penoles Project include
payments to Riverside of $1,350,000 in cash and the payment of a further
$1,500,000 in cash and/or Morro Bay shares, at Morro Bay's election subject to
certain conditions. Morro Bay can earn an additional 14% interest in the project
by paying $30,000, incurring an additional $5,000,000 in exploration
expenditures and paying an additional $750,000 in cash and/or Morro Bay shares,
again at Morro Bay's election subject to certain conditions. Further details are
available on the Company's website at www.rivres.com. 


Transaction Details: 

To acquire its interest in the Penoles project from Sierra Madre, Morro Bay
issued to Sierra Madre 16,000,000 common shares (the "Common Shares") at a
deemed price of $0.10 and 8,000,000 common share purchase warrants, each
exercisable into one common share at a price of $0.15 until June 15, 2014 and
thereafter at a price of $0.25 until their expiry on the first anniversary of
the date of their issuance (the "Warrants"). Sierra Madre has agreed to
distribute the 16,000,000 Common Shares and 8,000,000 Warrants so received pro
rata to its shareholders, and Riverside holds more than 12,500,000 Sierra Madre
common shares representing approximately 23% of the issued and outstanding
Sierra Madre shares. Pursuant to the terms of the Transaction it was agreed that
Riverside would receive its Common Shares and Warrants at Closing, and
accordingly Riverside has now received 3,705,974 Common Shares and 1,852,987
Warrants. Riverside understands that the balance of the Common Shares and
Warrants held by Sierra Madre will be distributed to its shareholders as a
dividend in kind. Riverside has agreed to waive its right to receive any portion
of the remaining Common Shares and Warrants pursuant to the dividend. 


The Common Shares and Warrants received by Riverside are subject to a four month
and one day hold period expiring on May 23, 2014. As a part of the Transaction,
Riverside has agreed to place 2,594,182 of the Common Shares in escrow until
December 31, 2014.
