January 24, 2012 – Vancouver, BC: Riverside Resources Inc. ("Riverside" or the "Company") (TSX-V: RRI) is pleased to report positive results from excavator trenching reporting  assays up to 1.4 g/t Au and providing further evidence to support the model that trenching has exposed the upper levels of a newly discovered, low sulfidation epithermal district. Trench results included 3.4 metres @ 0.65 g/t Au (including 1.7m of 1.2 g/t) and 15.89 metres @ 0.18 g/t Au (including 3.1m of 0.53 g/t). Results showed very encouraging dissemination beyond vein controls. Riverside and partner Mexigold Corp. are set to commence drilling shortly on the trench and rock assay target areas.

Following the recommended exploration program outlined in the published NI43-101 report, Riverside and partner Mexigold have completed an orientation soil sampling which shows a large consistent anomaly over the known veins. Soil sampling also matched favorably with the trench areas and may represent additional buried veins. The newly identified anomalies warrant further trenching and potentially a broad soil grid program to define additional drill targets. A more extensive soil program to the north could be conducted when drilling begins.

There are at least four large vein sets with individual veins ranging from 1-4m wide at surface within areas of multiple veining up to15m in width.  Recent trenching has more than doubled the width and number of identified veins. Veins now show widths in trenches of 10-30 meters with coincident anomalous geochemistry and strike lengths can potentially be extended significantly with further trenching work. The veins display anomalous gold and trace element geochemistry indicative of the upper portion of an epithermal precious metal system and warrants drill testing.

Property Details:

The property is over 230 km² of which less than 15% has been mapped and sampled thus leaving potential to extend existing targets and outline additional areas of interest. The trenches confirm a favorable NW structural vein control trend similar to many major districts in the Mesa Central Region such as, San Sebastian, Inde’, Mapami, and the Penoles District. The veins appear as anomalously mineralized silica ridges each up to 3.5 km in strike with a total strike length of over 12 km, and is still open.

Host rock Cretaceous sediments (Mezcalera Fm.), similar to the Fresnillo and Peñsaquito mines, host the veins at Pedernal. Reactive calcareous rocks may be at depth which affords an additional target feature. The high level epithermal environment is confirmed as reported in the SEDAR Filed National Instrument 43-101 Technical Report, and available on the Riverside website, www.rivres.com.

Exploration to-date shows encouragement for the discovery and definition of further vein mineralization. Riverside and Mexigold are excited to begin drilling these high-priority targets.
