Riverside Releases Drill Results from Catrina Project and Awaits Pedernal Project Results in Durango Mexico
March 15, 2012 – Vancouver, BC: Riverside Resources Inc. ("Riverside" or the "Company") (TSX-V: RRI) and partner Mexigold Corp. (TSX-V: MAU), are pleased to report on recently completed drilling at both the Catrina and Pedernalprojects in Durango, Mexico. The drill program at Catrinaconsisted of six diamond drill holes for a total of 1,615.40metres, and the campaign at Pedernal included seven diamond drill holes totaling 1,549.40 metres. Final results have now been received for the drilling at Catrina, while assays are still pending for the recently submitted core from Pedernal.
The drill program at Catrina focused on testing two of the existing six target areas on the property. Of particular interest was the connected Catrina-La Dura target area that covers a 1,400-metre long by 500-metre wide zone. The drill results within this zone failed to intersect significant gold or silver values, but indicator elements arsenic and mercury indicate that drilling did encounter the upper levels of an epithermal system.In four of the five holes drilled (CA-11-02 through CA-11-06), drilling encountered zones with elevated to strongly anomalousAs and Hg over drilled lengths between 20 and 96 metres. The levels of arsenic and mercury in the drill holes were substantially higher than those encountered in surface trenching, indicating that mineralization appears to be strengthening with depth at the Catrina-La Dura target.
A detailed interpretation of the first ever drill results at Catrinahas commenced and is expected to result in further targeting of additional drill holes on the Catrina-La Dura target. In addition,the untested Patos, Bordo, Palmitos, and Jaspe targets on the project show strong geochemical gold, silver, mercury, arsenicsoil anomalies and ground-magnetic high anomalies. Inducedpolarization geophysics conductors and resistive bodies on those targets that have so far been covered will help to focus potential drilling on these targets. Riverside plans to develop further drilltargets to test these favorable settings. The property is 14,814-hectares and less than 10% of the area has so far been tested at the Catrina concession.
The drill program at the Pedernal project, located 50 kilometresto the WSW of Catrina and 20 kilometres due west of thePenoles Mining District, was successfully completed and all samples have been submitted to the lab for analysis. ThePedernal drill holes were targeted to test favorable surface rock-chip and trench gold assays on three outcropping mineralizedquartz vein zones, the Tablones, Milpa, and Ranchito vein systems. Assay results are pending, but examination of the core indicates that the targeted mineralized zones were encountered in most drill holes, consisting of variable degrees of quartz veining with varying amounts of accompanying pyrite, calcite, chlorite, and specular hematite. The vein textures at Pedernal(abundant matrix-supported breccia, drusy quartz, and cockscomb quartz) suggest a strong epithermal system; the four principal vein zones have individual strike lengths up to 3.5 kilometres and a combined strike length of 12 kilometres. The strike length remains open as it appears to extend further under shallow post-mineral alluvial cover.
