Complete Summer Exploration Program in British Columbia 
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/25/12 -- Riverside
Resources Inc. ("Riverside" or the "Company") (TSX
the successful completion of the 2012 exploration program at the
Flute and Lennac Designated Projects located near Smithers in Central
British Columbia (BC). The Company is pleased with exploration
results to-date and looks forward to upcoming diamond drill results
from Lennac, further reverse circulation (RC) drill results from
targets on both properties, and generating additional targets and
Designated Projects for the Alliance with Antofagasta moving forward. 
Over the course of the summer field season, Riverside undertook
airborne geophysical surveys (News release August 8, 2012), ground
geophysical induced polarization (IP) surveys, reverse circulation
(RC) drilling, diamond drilling and geological mapping and
prospecting as part of an aggressive exploration program on the Flute
and Lennac properties. A total of 1,485 metres have been drilled in 4
diamond drill holes on the Lennac property and a combined total of
1,987 metres has been drilled in 93 top-of-bedrock RC drill holes at
Flute and Lennac during the 2012 summer exploration program.  
Two of the diamond drill holes, LLDH-12-01 and LLDH-12-02, were
designed to test areas of known mineralization to depth at the West
Zone on the Lennac property, for a total of 801 metres. Historic
drilling at the West Zone was completed mostly by shallow percussion
drill holes; historic diamond drilling was limited and several holes
terminated in mineralization. Drill holes LLDH-12-03 and LLDH-12-04
were completed on prospective areas at the East Zone, following up on
results from airborne geophysics (Magnetics), RC drill results and
historic drilling for a total of 678 metres. Results from the diamond
drilling at Lennac are pending and will be released as they are
Two new copper-porphyry targets with strong potential were identified
during the 2012 exploration season, the Cougar Zone on the Lennac
property and the Mouse Zone on the Flute property. In addition to the
61 RC drill holes test
ing the main trend at Lennac, a further 18 RC
drill holes were completed at the Cougar Zone (Lennac), and 14 drill
holes were completed at the Mouse Zone (Flute).  
The Cougar Zone on the Lennac Property encompasses historic, broadly
coincident IP and copper-in-soil geochemical anomalies. The Cougar IP
and soil anomalies sit peripheral to a large, circular magnetic high
seen in 2012 airborne geophysical results. Ground geophysical IP
surveys completed at Cougar over the 2012 season confirmed and
significantly expanded the historic IP anomaly to the south and to
the east. Base-of-Till/Top-of-Bedrock sampling with an RC drill rig
was undertaken with 18 RC drill holes over the Cougar Zone, with
several of the holes intersecting altered volcanics, porphyry
intrusives, and associated sulphide mineralization in bedrock chips.
Anomalous copper was returned from the RC top-of-bedrock drilling
samples over a 1.2km strike length. 
The Mouse Zone on the Flute Property also encompasses historic,
broadly coincident IP and soil anomalies; outcrop is sparse but
altered volcanics cut by porphyry dykes are seen at one location to
the northwest. The Mouse Zone lies due east of the Skinbone fault, a
regional structure thought to form the western boundary of the Babine
Graben that projects through towards the past producing Bell and
Granisle mines. Base-of-Till/Top-of-Bedrock sampling with an RC drill
rig was undertaken with 14 RC drill holes over the Mouse Zone,
several of which intersected altered volcanics and porphyry
intrusives. Trace sulphide mineralization was noted in the most
north-westerly of the RC drill holes, in closest proximity to the
north-striking structural corridor seen in airborne geophysics. Assay
results from RC drilling at the Mouse Zone are pending. 
Further RC drilling to better delineate and expand areas of
copper-porphyry mineralization at the Mouse and Cougar Zones is
planned for follow-up exploration in 2013.
