The Santa Rita project is a 48.6 square kilometer (4,860 hectare) Exploration License in central El Salvador. Santa Rita, located roughly 10 km from the Company's flagship El Dorado gold project, is an epithermal quartz-calcite vein system that was discovered as a result of reconnaissance-style sampling of float, sub-crop and outcrop. The results of this sampling program indicate the presence of high-grade gold at Santa Rita. The Santa Rita project provides excellent exploration blue sky within El Salvador that will both complement and benefit from the Company's on-going El Dorado exploration.

The Trinidad vein, one of two known vein structures on the project, has to date been traced over a distance of 1400 meters in a northwest -- southeast direction. Seven rock samples collected across the Trinidad vein over a 500 meter strike length at the southern end of its exposure yielded the following results: 6.43 g/t gold over 1.5 meters; 14.59 g/t gold over 1.0 meter; 25.76 g/t gold over 1.5 meters; 118.29 g/t gold over 1.5 meters; 32.67 g/t gold over 0.5 meters; 12.64 g/t gold over 2.0 meters; and 59.52 g/t gold over 1.5 meters. The northernmost 900 meters as well as a 200-meter segment of the vein within the southern high-grade area (where it crosses a hill) are likely above the productive interval of the Santa Rita epithermal system but surface sampling results yielded assays up to 5 g/t gold over similar vein widths.

Pacific Rim has completed a baseline environmental assessment of the Santa Rita project and has been granted the necessary permits to drill test this exciting gold discovery. A drill program at Santa Rita is expected to commence in late 2006.
