VANCOUVER, July 22, 2011 /PRNewswire/ - Riva Gold Corporation (TSX-V: RIV) ("Riva" or "the Company") announces results from its mapping, trenching and diamond drill program on its Honey Camp Property. Three historical vein systems, the Rainbow, Alma and Camp veins, located within a 2.4 kilometre by 0.9 kilometre area on the Honey Camp Property (the "Area"), were tested by mapping and trenching followed by 16 diamond drill holes totalling 2,886 metres (of which two holes were abandoned due to poor ground conditions). Two additional historical vein systems within the Area, the Brian & Brenda and Sobers Hills veins, were examined by mapping and trenching. The five historic vein systems are all hosted in sheared, quartz-carbonate alteration zones, cross-cutting lavas, tuffs and sediments. "We are encouraged by the surface results that we have received from the historical vein systems we have been focusing on," commented Richard Warke, Riva's chairman and CEO. "However, more work needs to be completed on the Honey Camp Property to help us more fully understand the geological structure of the area and is an important step in order to determine our focus going forward." Riva focused its exploration efforts on the five historical vein systems within the Area. The mapping, trenching and diamond drilling results from the three historical vein systems are summarized below: Rainbow Vein System The Rainbow vein system (the "Rainbow Veins" or "Rainbow") is the centrally located southern most historical vein system in the Area and indicates a strike length of 395 metres, of which 200 metres was tested by four trenches and nine diamond drill holes totalling 1,516 metres (two drill holes were abandoned due to poor ground conditions). The area of veining corresponds with a significant potassium radiometric anomaly. The trench and drill hole results from the five sections across the Rainbow Veins identified significant surface assay results in trench RB-#1 (0.91 g/t Au over 22.00 metres) and lower drill intersection assay values (the most significant demonstrated in DDH RB-11-01 returning 0.91 g/t Au over 0.50 metres and 1.07 g/t Au over 1.00 metres). Trenching and drilling were completed along five sections approximately 50 metres apart.
