These drill results are part of an on-going program that is expected to comprise approximately 20 drill holes and total roughly 7,000 meters of diamond drilling on a variety of vein targets within the El Dorado District.

ABOUT THE DRILL RESULTS The first drill hole (P02-203) intersected several veins within the Rosario Vein system (located 200 meters east of Minita). The first vein assayed 31.93 g/t Au and 257 g/t Ag over a drill length of 1.45 m starting at 96.15 m. A second vein was intersected at 104.8 m that assayed 24.84 g/t Au and 163 g/t Ag over a length 1.15 m. A lower grade vein was encountered at a depth of 34.5 m that averaged 6.81 g/t Au over a length of 2.3 m. Drilled easterly at a dip of 54 degrees, this hole was designed to cross the Rosario and Veta Grande veins perpendicular to their strike. The Rosario Vein has a strike length of 500 m and was intersected at an elevation of 310 meters above sea level Meters Above Sea Level is a standard metric measurement of the elevation of a location in reference to mean sea level.

Veta Grande was intersected further down hole but grades did not reach the 6 g/t Au cutoff. The upper 319 meters of the second drill hole (P02-204) has also been assayed and failed to hit mineralization Mineralization The process by which the body uses minerals to build bone structure.

This hole was designed to cross the southern Moreno and Varicose Veins Varicose Veins Definition Varicose veins are dilated, tortuous, elongated superficial veins that are usually seen in the legs. Description in a westerly direction. Assays are still pending on the lower 80 meters of this hole. Drilling has been accelerated at El Dorado by the addition of a second diamond rig, which will continue to scout drill the abundant targets in the central part of the El Dorado District. Drill hole 205 was designed to test the El Dorado Vein and continue to the down-rake extension of the Minita resource. Hole 206 is designed to test the south Minita, Zancudo and El Dorado Veins. Hole 207 is also designed to cross the Veta Grande, the Varicose Vein varicose vein, superficial vessel that is abnormally lengthened, twisted, or dilated, seen most often on the legs and thighs. Varicose veins develop spontaneously, and are usually attributed to a hereditary weakness of the vein; the valves in the vein that keep the and the Rosario Vein at the productive interval, approximately 300 meters north of hole 203. Results are expected for these holes next month. SURFACE WORK CONTINUES TO OUTLINE NEW TARGETS Targeting continues using trenching, surface rock sampling and detailed geologic mapping. This work has identified several very attractive targets in the central part of the district. Two trenches along strike to the north of the Minita resource have been constructed on the Minita Vein and assayed 12.67 and 10.00 g/t Au, respectively. The Minita Vein is narrow at the surface (less than 0.5 meters) but averages 3.3 meters in width at depth in the resource area. Trenching on the northern Moreno Vein has revealed another attractive target. Assays range from 0.19 to 11.37 g/t Au in the five trenches cut across the vein system, sampling 200 meters of strike length. Two other veins have been discovered to the east of Moreno, the DVDA DVDA DVD Association DVDA Digital Versatile Disc Audio DVDA Digital Video Disc Audio DVDA Digital Video Distribution Amplifier DVDA Dvd Audio and the Montecristo Veins. Initial sampling here is also very encouraging with assays of 8.84 and 8.40 g/t Au, respectively. The veins in this area are highly anomalous considering they are located at elevations ranging from 420 to 450 meters above sea level - high above the productive interval (100-250 m above sea level). "This is a great start to an extensive 20 hole exploration program specifically designed to get a sense of the high-grade gold potential in the central part of the district before following up with definition drilling of the best hits. The targeting work is progressing smoothly and we recently commenced the fifth drill hole (207). I'm especially pleased with the efficiency being achieved as each hole has tested at least two targets, multiplying the chances of discovery," stated Tom Shrake, Pacific Rim's CEO (1) (Chief Executive Officer) The highest individual in command of an organization.

ABOUT EL DORADO The El Dorado District is an adularia-sericite type epithermal gold system located in El Salvador that hosts bonanza gold. Over 35 known quartz veins have been identified and these veins have a total strike length of over 18 kilometers. Diamond drilling by previous workers concentrated on shallow, near-surface intervals. Limited past drilling at deeper intervals demonstrated that the highest grade gold was encountered in a "Productive Interval" that occurs in the elevation range of approximately 100 to 250 meters above sea level (ASL ASL - Algebraic Specification Language ). This equates to a depth below surface of roughly 150 to 300 meters. Only two veins have been systematically drill-tested in the Productive Interval by previous workers. The current drill program is designed to test a number of high-priority vein targets in the Productive Interval seeking high-grade chutes of gold mineralization. The Minita Vein system was mined in the mid-1900's and currently hosts an indicated resource of 799,200 tonnes with an average grade of 13.7 g/t gold and 97.9 g/t silver below the old stopes Stopes , Marie Carmichael 1880-1958.

This resource totals over 350,000 ounces of high-grade gold. Details of this resource estimate and a summary of the geology of the El Dorado project are presented in a technical report prepared for Dayton Mining Corporation (a predecessor company of Pacific Rim Mining Corp.) by Mr. P. LaCroix, P.Eng (a Qualified Person as defined in National Instrument 43-101) entitled "Resource Update Nueva Esperenza & El Dorado Mine Area - El Dorado Project - El Salvador", dated February 8, 2002. The report is summarized in Dayton's most recent Annual Information Form, available on SEDAR SEDAR System for Electronic Document Analysis and Retrieval SEDAR Southeast Data, Assessment, and Review . 43-101 DISCLOSURE Pacific Rim's exploration work on the El Dorado project is being supervised by William Gehlen a Certified Professional Geologist with the AIPG AIPG American Institute of Professional Geologists (No. 10626), an employee of Pacific Rim and a Qualified Person as defined in NI 43-101.
