("Riverside" or the "Company") (TSX VENTURE:RRI)(PINK SHEETS:RVSDF)(FRANKFURT:R99) is pleased to announce that, further to its news release dated February 11, 2011, Riverside and Mexigold Corp.

The drill-ready Durango Properties cover an area of more than 760 square kilometers and are located in Durango and northernmost Zacatecas, Mexico.

Mexigold Corp. ("Mexigold") can acquire a seventy-five percent (75%) interest in the Durango Properties by issuing Riverside an aggregate 2,600,000 Mexigold shares, making total cash payments of $500,000 to Riverside, and incurring an aggregate $4,000,000 in exploration expenditures on the Durango Properties within 36 months of the Agreement. Included in the exploration expenditure requirements is a commitment to drill a minimum of 3,000 metres on the Durango Properties within 12 months from the date of the Agreement.

The Durango Properties

The Durango Properties are located in the States of Durango and Zacatecas, Mexico. The Durango Properties include the "Catrina," "Escondida" and "Pedernal" mineral exploration concessions covering over 76,000 hectares. All of these projects were developed through the culmination of 2-1/2 years of generative exploration and targeting through the Riverside-Kinross Exploration Alliance. Riverside's geologists completed extensive groundwork identifying multiple drill ready targets.

The Catrina Gold Project covers over 14,000 hectares and located within the prolific gold-silver belt of the Mesa Central Region in Durango. Geochemistry of the alteration zone shows a strong gold anomaly extending over a strong of more than 3 km². The geophysical IP response chargeability, trace element geochemistry (gold-silver-lead) and the mapped geology at Catrina are similar to Goldcorp's Camino Rojo. Riverside's exploration program on the Catrina property identified four principal target zones and a first phase 10-hole 2,600 metre drill program has been designed to test geology and geochemistry of the system.

The Escondida Gold Project is comprised of over 37,000 hectares in northern Zacatecas, situated within a NW trending structural corridor hosting mines such as Castillo, San Sebastian and Miguel Auza. Riverside completed an initial exploration program on the property and identified two east-west striking mineralized trends within a 2.1 km by 1.3 km zone defined as the primary target area. The outcropping mineralized structures and projection beneath alluvial cover show many similarities to the nearby Valenciana and San Jose de Reyes mining districts. A first phase 10-hole 2,500 metre drill program has been recommended.

The Pedernal Gold Project is comprised of over 24,000 hectares, located 60 kilometres north of the town of Rodeo, and immediately west of the Peñoles District in northern Durango State. The Pedernal project contains anetwork of parallel veins with moderate argillic alteration and indications of what appears to be the upper part of an epithermal system. Recent exploration by Riverside identified four principal northwest trending mineralized zones with up to 3.5 km of continuous veining and total vein strike lengths of up to 12 km. A first phase 4-hole 1,000 metre drill program has been recommended to test the potential depth of the system.
