QUESNEL, BRITISH COLUMBIA--(Marketwire - May 10, 2011) - Richfield Ventures Corp. (News - Market indicators) ("Richfield" or the "Company") is pleased to report drill results for eight holes of the 2011 30,000 metre drill campaign to expand and delineate the resource on the Blackwater Gold Project. The project is approximately 100 km south of Vanderhoof, BC.

Gold mineralization is seen in every hole with BW 146 returning the best result, an intersection of 378 metres grading 1.09 g/t Au. The eight vertical holes were collared on the northern part of the Blackwater Gold Project, in which Richfield has a 75% interest and Silver Quest Resources Ltd. (TSX VENTURE:SQI) has a 25% interest, in which Richfield is the operator of a joint venture.

BW 141, BW 143 and BW 148, were drilled on the northeast in the Gold Zone. Two holes, BW 144 and BW 147 were drilled in the centre of the joint venture ground. Three further holes, BW 142, BW 145 and BW 146, were drilled in the northwest. BW 142 and BW 145 were drilled from the same collar. Both were abandoned because of drilling difficulties.

Out of a total 2466.8 metres drilled in the eight holes composited sections averaging 0.3 g/t Au and better total 1505 metres, about 61% of the total drilling. Out of a total 2269 samples 1041 returned values above 0.3 g/t Au, some 46%.

Peter Bernier, RVC president comments, "We are naturally excited by the good gold grade and the long intersections in many holes. Drilling in the Gold Zone also continues to hold up well. Most of these holes are outside of our current resource estimate."

Drill map and strip logs for individual holes reported here will be posted on the company website.

Quality Assurance

Richfield has implemented a rigorous quality assurance/quality control program at the Blackwater property using best industry practice and supervised by Dirk Tempelman-Kluit. The program includes chain of custody of samples from drill to laboratory. Drill core is sawn in half at the property and for each sample half of the core from one metre intervals is placed in plastic bags and sealed. The remainder is retained in core boxes stored at the project camp.

A standard sample, a blank sample, or a duplicate sample is inserted into the sample stream every tenth sample. Three certified ore assay laboratory standards are used in the program, and are supplied by CDN Resource Laboratories Ltd., an independent laboratory located in Langley, BC. Samples including the blanks, standards and duplicates, are shipped by bonded courier to Eco Tech Stewart Group Laboratories in Kamloops, BC, an internationally recognized analytical services provider. Rejects selected at random are sent to Acme Labs of Vancouver, BC for check assays. In total 2466.8 metres was drilled in eight holes; 2269 samples were prepared. A further 82 blanks, 82 standards and 84 duplicates were inserted in the sample stream. As well 75 samples were selected for check assay. Total quality control samples were 323, about 14% of the samples analyzed. Richfield detected no significant QA/QC issues during review of the data.
