Here's some news: NEWS RELEASE TRANSMITTED BY CANADIAN CORPORATE NEWS FOR: PACIFIC RIM MINING CORP. TSE SYMBOL: PFG NOVEMBER 18, 1999 Pacific Rim Announces Additional Surface Sampling Bolsters Luicho Target VANCOUVER, BRITISH COLUMBIA--An on-going program of continuous rock chip sampling of surface exposures at Pacific Rim Mining Corp.'s Luicho project in southern Peru has begun to fill in and expand the Luicho gold prospect. A total of 1,600 samples have been collected by Pacific Rim to date. The average grade of all of these samples is 2.06 g/t gold. Most of these samples were collected from a 250 meter wide, north to northeast-trending structural corridor related to a complex series of strike slip faults. These faults have fractured the host rocks and structurally prepared them for the deposition of gold mineralization. The structural corridor is now known to host mineralization over a strike length of 1,500 meters. The stratigraphy at the Luicho target consists of a series of sandstone horizons capped by a relatively impermeable shale unit. The sandstone horizons are the dominant host rock for mineralization at Luicho. The shales have been largely eroded, with only local scabs remaining. The vertical relief along the corridor is 350 meters and mineralization has been identified over a vertical stratigraphic thickness of 200 meters. The structural corridor has been divided into a number of zones (the Central, Northeast and South zones) based on the structural preparedness and intensity of mineralization. Of the 1,600 samples collected to date, 672 are from the Central zone (550 meters long by 250 meters wide), 486 are from the Northeast zone (700 meters long by 400 meters wide) and 19 are from the South zone (300 meters long by 250 meters wide and open to the south). The results of the sampling to date in each zone are summarized in the table below. /T/ Zone # of average % of samples average grade samples grade of exceeding samples exceeding in total total 0.31 g/t 0.31 g/t (gold) gold cutoff gold cutoff Northeast 486 1.05 g/t 65% 1.54 g/t gold Central 672 3.66 g/t 73% 4.99 g/t gold South 19 8.97 g/t 100% 8.97 g/t gold Total for structural corridor 1177 2.67 g/t 70% 3.75 g/t gold /T/ Individual samples collected by Pacific Rim are continuous rock chip samples, from 2 to 3 meters in length. These samples are most often strung together to produce continuous rock chip channels 10 to 100 meters in length. Sampling is supervised by Pacific Rim's senior geologists Dave Ernst and Pete Dilles and the Luicho program is ultimately supervised by Tom Shrake, CEO of the Company. Samples are assayed by Bondar Clegg, an ISO9002-registered analytical laboratory in Vancouver, BC, after first being prepared at their facility in Lima. A check assay program is on-going with Chemex Labs. Pacific Rim has commissioned a series of aerial photographs of the Luicho area, and topographic maps are being constructed. Detailed geologic mapping of the prospect and surrounding area will begin when these base maps are completed. A contractor has been selected for the construction of an access road to the site. Road construction is scheduled to being in January, 2000. Surface and subsurface rock sampling is continuing on a daily basis with two sample crews and a small army of local support workers. This on-going sampling effort will take several months to complete and results will be announced regularly. The Company will make use of technical climbers to sample the vertical cliff faces, in order to better define the surface mineralization. In addition reconnaissance prospecting of Pacific Rim's 100% optioned Santiago III claim (the Luicho claim) and its 6,000 hectares of 100% owned claims is being undertaken in an effort to identify additional mineralized centers. A map outlining the new continuous rock chip samples is available at the Company's website (www.pacrim-mining.com) or by fax from the Company. On behalf of the board of directors, Thomas C. Shrake, CEO This news release contains forward-looking statements regarding upcoming programs. Actual results may differ materially from those currently anticipated in such statements.
