CHIHUAHUA, MEXICO--(MARKET WIRE)--Jul 22, 2008 -- Paramount Gold and Silver Corp. (Toronto:PZG.TO - News)(PZG - News)(Frankfurt:P6G.F - News)(WKN: A0HGKQ) announces assay results from six additional drill holes at its Cieneguita Project from their strategic alliance with Mexoro Minerals (Other OTC:MXOM.OB - News). It is in the same mineralized trend and only 20 km away from Goldcorp's El Sauzal mine, Mexico's largest producing gold mine and adjacent to Paramount's Andrea project. Cieneguita was last in production by Glamis Gold Ltd. between 1995 and 1998 prior to its acquisition by Goldcorp Inc.

Drill hole CI-25 intersected 46.50 m of 1.10 g/t Au, 332.60 g/t Ag, 0.35% Pb & 0.66% Zn, including: 10.95 meters of 2.13 g/t Au, 976 g/t Ag, 0.38% Pb & 0.96% Zn; and 13.45 meters of 1.30 g/t Au, 149.53 g/t Ag, 0.57%Pb & 0.68% Zn. Within CI-25 there were two very narrow high grade veins which intersected 0.15 m of 8.23 g/t Au, 5500 g/t Ag and 0.1 m of 8.84 g/t Au, 3130 g/t Ag

Drill hole CI-27 intersected 85.50 m of 0.70 g/t Au & 54.46 g/t Ag including: 7.50 meters of 1.54 g/t Au, 148.66 g/t Ag, 0.15% Pb & 0.32%Zn and 9.00 meters of 1.07 g/t Au, 82.47 g/t Ag, 0.18 % Pb & 0.22% Zn

Drill hole CI-29 intersected 30 m of 0.66 g/t Au, 58.75 g/t Ag, 0.45% Pb & 0.58% Zn including: 10.50 meters of 1.01 g/t Au, 92.71 g/t Ag, 0.37% Pb & 0.33% Zn,; 15 m of 1.77 g/t Au & 66.65 g/t Ag including 6 m of 3.55 g/t Au and 116.75 g/t Ag; 64.60 m of 0.56% Pb & 0.80% Zn; and 12.80 m of 0.28% Pb & 0.70% Zn.

The current drill program continues to intersect high grade mineralization both along strike and at depth. Drilling continues at this project to help better understand this mineralized system and to test its depth potential.

The Summary of these assay results are seen in the table below (visit http://www.paramountgold.com/projects/san_miguel_maps.asp for a map showing the locations of holes CI-01 to CI-31).
