Riverside Resources and Partner Morro Bay Resources Drill 388.4 g/t Silver Over 22.7 Metres at the Penoles Gold-Silver Project in Durango, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Jun 9, 2014) - Riverside Resources Inc. ("Riverside" or the "Company") (TSX VENTURE:RRI)(PINKSHEETS:RVSDF)(FRANKFURT:R99), is pleased to announce new drill results from the Jesus Maria Silver Mine area at the Peñoles Project (the "Project") in Durango, Mexico, which is being funded by Morro Bay Resources. Twenty three (23) HQ sized core holes were drilled on the property, for a total of 2,143 metres during the most recent drill program with results still pending for 6 holes. The recent program discovered a new zone of mineralization and structural preparation (referred to as the "Jesus Maria South Zone") intersecting and trending southwest from the Jesus Maria Vein. The Jesus Maria South Zone had not been systematically tested and apparently never worked by previous mining. The first two drill holes that intersected the new zone, (JM DDH 14-10 and JM DDH 14-24) returned the best near surface intervals of silver mineralization intersected at the Peñoles Property since Riverside acquired the property in 2007.

The first hole drilled (JM DDH 14-10) was a 30 metre step out, south from the final hole (JM DDH 13-9 "Hole 9") of the 2013 program (view www.rivres.com for maps and images). This drill hole, (JM DDH 14-10) intersected an approximately 41 metre wide near-surface mineralized interval averaging 123.9 g/t silver and more than 0.5 g/t gold, including a 4.25 metre interval that assayed 732.2 g/t silver and 1.20 g/t gold. The second hole, JM DDH 14-24, confirmed significant widths of mineralization, with 70.8 m interval averaging 147.8 g/t silver including a 22.7 m interval that returned 388.4 g/t silver.

Assay results for the drill holes received to date from the Jesus Maria South Zone, JM DDH 14-10 and JM DDH 14-24, are summarized below:

(All reported intervals are core lengths, true widths have not yet been determined)

Six additional holes (JM DDH 14-25 through JM DDH 14-30) have been drilled to investigate the potential continuity of mineralization at Jesus Maria South Zone to the east of the JM DDH 14-24 location. Assay results for these six holes will be released as soon as they become available and have been interpreted.

Riverside's President and CEO, John-Mark Staude stated, "Riverside is pleased with the drilling and discovery of the Jesus Maria South Zone and looks forward to receiving further assays from the remaining six holes. Collectively this zone so far has a strike extent of drilling of over 250 meters. The expanded mineralization found at Jesus Maria combined with the Capitan Gold Zone, untested San Rafael Mine area and numerous other prospective targets provide plenty of upside as the Peñoles Project continues to move forward."

Other assayed holes from the current campaign include drill holes JM DDH 14-11 through JM DDH 14-23, a series of vertical and inclined holes spaced at approximately 50 to 100 metre intervals along the Jesus Maria Vein which provide near surface extension to the shallow mined area. The Jesus Maria Vein holes (view www.rivres.com for maps) were designed to test for potential lateral extensions of the mineralized zone developed in the historical Jesus Maria mine region and to some extent began to extend the depth which remains wide open. The drilling successfully extended the confirmed strike length of the Jesus Maria Vein approximately 500 meters westwards, and intersected the vein at the expected depths, showing good continuity. The vein remains open at depth and along strike. The drill holes encountered encouraging mineralization zones as tabulated below. These results are currently being integrated into the Jesus Maria geological model, and will be commented on in more detail as the analysis is completed.

(All reported intervals are core lengths, true widths have not yet been determined)

Two drill holes (CDDH-14-49 and CDDH-14-50) were designed to test the Capitan Hill Zone target but were terminated early without reaching target depth due to local ground conditions and were not submitted for assay.

Results of previous drill programs completed at the Penoles Project are summarized in a recent N.I. 43-101 completed by Morro Bay Resources filed on SEDAR (www.sedar.com).

About the Peñoles Project:

The Peñoles Project is located in the Durango silver-gold belt in north-central Mexico and is currently owned 100% by Riverside. The recently completed drill program was conducted pursuant to a commitment by Morro Bay Resources Ltd. ("Morro Bay") to perform $750,000 of exploration work on the property during the first part of 2014. Morro Bay can complete its option to earn an initial 51-per-cent interest in the property by paying USD$1.35-million in cash to Riverside and paying USD$1.5-million worth of Morro Bay shares by June 30, 2014. For more information see Riverside press release dated January 23, 2014.

There are approximately eleven targets on the Peñoles Project, including the Capitan Gold Zone, the Pinchanzo Zone (see Riverside press release dated May 23, 2012), potential west extensions of El Capitan (referred to as the West Extension), a new target area located to the northwest of El Capitan (referred to as Santa Theresa) and the previously mined Jesus Maria and San Rafael Ag- Au-Pb-Zn mines. The district is highly prospective with active mining operations nearby and has proven to be a cost effective region where projects can be efficiently developed towards production.

The Capitan Gold Zone is an advanced epithermal prospect with 45 drill holes and 6,945 metres of total drilling so far, with geological work to-date indicating potential for a bulk tonnage gold style system at El Capitan, with the geologic interpretation indicating vectors for expansion with further drilling.

The 23 drill holes and 2,143 metres of recently completed drilling bring the aggregate drill figures to 31 drill holes over 3,000 metres at Jesus Maria. The 2013 drilling intercepted a semi-parallel sequence of upper silver-carbonate veining as well as the main quartz-rich Ag-Au-Pb-Zn Jesus Maria vein zone. Underground exploration and sampling of the old workings also found silver bearing carbonate veins, which prior to this recent work was not known and demonstrates larger potential for the Jesus Maria vein system than previously recognized. The 2014 drilling has encountered some of the widest and strongest silver mineralization to-date and builds on previous work with significant exploration upside still remaining at Jesus Maria and surrounding targets.

Qualified Person and QA/QC:

The scientific and technical data contained in this news release pertaining to the Peñoles Project was reviewed by Howard Davies, MAIG - VP Exploration, a non-independent qualified person to Riverside Resources, who is responsible for ensuring that the geologic information provided in this news release is accurate and who acts as a "qualified person" under National Instrument 43-101 Standards of Disclosure for Mineral Projects.

According to Morro Bay, all drill cores were placed in numbered boxes and transported to Morro Bay's secure core facilities by the drill contractor. Following detailed core logging all core was cut using a diamond bladed core saw under the direct supervision of Morro Bay's geologic staff with half of the core kept on site in the original core boxes. All drill samples were sealed in numbered plastic bags and transported to Inspectorate America Assay labs facility in Durango City for prep work and analyzed at their facilities in Reno, NV, USA. Inspectorate America is certified for the provision of assays and geochemical analysis (ISO:9001-2008). All samples were prepared using standard industry preparation methods followed by fire assay analysis and aqua regia digest for trace elements. All samples with greater than 10 g/t Au or 100 g/t silver were additionally tested by fire assay with a gravimetric finish. Morro Bay has included appropriate industry certified standards and blanks within the drill core sample stream in addition to the standards and duplicates included as part of the Inspectorate QA/QC program.
