Paramount Gold and Silver Discovers Continuity of High Silver Values Between San Antonio and La Veronica on Its San Miguel Project

1.2 km. unexplored gap returns intercepts assaying up to 1,820 g/T of silver

WINNEMUCCA, NEVADA--(Marketwire - June 21, 2012) - Paramount Gold and Silver Corp. (NYSE MKT:PZG)(NYSE Amex:PZG)(TSX:PZG)(FRANKFURT:P6G)(WKN:A0HGKQ) ("Paramount") reported today that results from four new shallow core holes on its 100%-owned San Miguel Project in Mexico confirm the continuity of mineralization along the 7.5 km. long Guazapares Megastructure. These holes were drilled into the 1.2 km untested gap separating the San Antonio and La Veronica deposits. (See maps below) The results demonstrate that San Miguel's Guazapares is one of the longest continuously mineralized structures in the Sierra Madre Metallogenic Belt.

Paramount started earlier this year to drill the untested gaps between deposits to evaluate the potential of continuous mineralization along the structural corridor called the Guazapares Megastructure. A 1.3 km gap south from La Union toward Santa Clara, and a 1.2 km gap north of San Antonio toward La Veronica, provided significant opportunity to expand these known deposits.(See map below) Preliminary drilling into both gaps has now confirmed continuity of mineralization and encountered intersections of high-grade precious metals. Paramount will continue to drill these areas on a more systematic pattern to define and model the mineralization.

Paramount's CEO Christopher Crupi commented that "this first pass shallow drilling was designed to determine if the structure continues into the gaps, its orientation and if it is mineralized. This part of the program has been a resounding success. The next step-now in progress-is to go after higher gold grades by determining their 'optimum' elevation within the structure. At the San Miguel Project, we have found that 300 meters or more of vertical extent on the main structures carry bonanza grades. This concept of optimum elevation has helped to significantly increase the high-grade mineralization at La Union, San Miguel Vein and Don Ese. Our team is now confident that the same will hold true along the entire length of the Guazapares Megastructure."

Data from these new holes will not be included in the updated mineral resource estimate for the San Miguel Project which is scheduled for release in August, 2012. Drilling at San Miguel continues with two core rigs.

Results from the first four holes drilled into the San Antonio-Veronica gap are as follows:

These holes were drilled to intercept the interpreted structure at right angles. Although, additional drilling and modeling are required to define exact true widths of the structure, it is believed they will be approximately 70% to 80% of the reported intercepts.

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 and approved this press release. An ongoing quality control/quality assurance protocol is being employed for 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.

About Paramount Gold

Paramount Gold is a U.S. based exploration and development company with multi-million ounce advanced stage precious metals projects in Nevada (Sleeper) and northern Mexico (San Miguel). Fully funded exploration programs are now in progress at these two core projects which are expected to generate substantial additional value for our shareholders. Engineering studies are scheduled for completion in 2012 to define a development path and economic valuation for each project.

The 100% owned San Miguel Project consists of 150,160 hectares (371,053 acres) in the Palmarejo District of northwest Mexico, making Paramount the largest claim holder in this rapidly growing precious metals mining camp. The current work program at San Miguel is part of Paramount's strategy of expanding and upgrading known, large-scale precious metal occurrences in established mining camps, defining their economic potential and then partnering them with nearby producers. The San Miguel Project is ideally situated near established, low cost production where the infrastructure already exists for early, cost-effective exploitation.

Paramount also owns 100% of the Sleeper Gold Project which is emerging as one of Nevada's largest new undeveloped gold resources. See the Global Resource table below.

Cautionary Note to U.S. Investors Concerning Estimates of Indicated and Inferred Resources

This news release refers to mineral resource estimates which may use the terms "measured and indicated resources" and "inferred resources". We advise U.S. investors that while these terms are defined in, and permitted by, Canadian regulations, these terms are not defined terms under SEC Industry Guide 7 and not normally permitted to be used in reports and registration statements filed with the SEC. "Inferred resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of a feasibility study or prefeasibility studies, except in rare cases. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves", as in-place tonnage and grade without reference to unit measures. U.S. investors are cautioned not to assume that any part or all of mineral deposits in this category will ever be converted into reserves. U.S. investors are cautioned not to assume that any part or all of an inferred resource exists or is economically or legally minable
