| WINNEMUCCA, NEVADA--(Marketwire - June 15, 2011) - Paramount Gold and Silver Corp. (NYSE Amex:PZG)(TSX:PZG)(FRANKFURT:P6G)(WKN:A0HGKQ) ("Paramount Gold") announced today new assay results from its ongoing drilling program at the San Miguel project in Mexico have extended the bulk-mineable San Francisco deposit and discovered a new, closely-spaced swarm of higher grade gold-silver veins named Santa Clara. Drilling in 2011 has been focused on testing several new targets and expanding known mineralized areas. Drilling continues to enlarge the San Francisco area, one of the larger mineralized zones at San Miguel, which has been extended approximately 200 meters along strike with this year's drilling. Excellent results were also intersected at a new target area named Santa Clara where follow up drilling will be carried out this year (See map of San Francisco Area). Only five holes were permitted and drilled to date on the promising Don Ese Sur target located 3.5 km south of last year's Don Ese high grade vein discovery. One of these holes generated two significant intercepts, with grades up to 78 g/t of silver, while the other four returned no significant values. However, Don Ese Sur remains an important target with more than 1.6 km of strike length left to explore and 15 more holes planned once permits are obtained. One of four initial holes drilled on the new La Verde and El Ojito targets produced an intercept with good grade while the other three had no significant intervals. (See map). Drilling continues at San Miguel with two core rigs to upgrade and expand resources in the main target areas, including San Miguel, San Francisco and San Antonio. Follow up drilling at the main Don Ese structure will also resume this year to increase the size and quality of the initial resource reported in early April 2011.

Although the intersections are believed in general to be the true width of the mineralized feature, additional drilling and modeling is required to confirm this conclusion. Exploration activities at San Miguel are being conducted by Paramount Gold de Mexico S.A de C.V personnel under the supervision of Glen van Treek, exploration vice president of the company and Bill Threlkeld, a Qualified Person as defined by National Instrument 43-101, who have both reviewed this press release. An ongoing quality control/quality assurance protocol is being employed during the program including blank, duplicate and reference standards in every batch of assays. Cross-check analyses are being conducted at a second external laboratory on 10% of the samples. Samples are being assayed at ALS Chemex, Vancouver, B.C., using fire assay atomic absorption methods for gold and aqua regia digestion ICP methods for other elements.
