Pacific Rim Mining Announces San Francisco Drill
Results
VANCOUVER, BRITISH COLUMBIA--Pacific Rim Mining Corp. has received the results from the final two holes completed in the Phase 1 reverse circulation drill program at their wholly-owned San Francisco project in northwestern Argentina. San Francisco is a low-sulfidation type epithermal occurrence, marked by highly anomalous trace element geochemistry and elevated precious and base metals.
Holes SF-12 and SF-13 were targeted to intersect a large north-south trending fault zone and coincident quartz vein that is believed to control mineralization at San Francisco. The results from these two holes are as follows:
Hole From To Length Au Ag Zn Pb
No. (m) (m) (m) (g/t) (g/t) (percent) (percent)
SF-12 263 284 21 0.28 44.8 3.3 1.2
SF-13 230 239 9 0.59 31.8
305 318 13 1.22 16.7
327 339 9 0.59 36.7
Mineralization at San Francisco is, typical of most low-sulfidation systems, markedly zoned. Holes SF-10 and SF-11 (previous reported in NR No. 99-15 on August 27, 1999) were the first two holes in the program to intersect the target fault-hosted quartz vein system, although they are believed to have penetrated this target too high in the system. Holes SF-12 and SF-13 are in the correct vertical position, as indicated by chemical and mineralogical zonation patterns. Bonanza-style low-sulfidation systems are generally small volume targets that require thorough drill programs in order to be adequately tested.
``We have moved the San Francisco prospect several steps forward with this modest initial drill campaign, states Tom Shrake, CEO. We are very encouraged by the results to date, which clearly demonstrate that additional drilling is warranted after we take the time to thoroughly evaluate the data generated in the Phase 1 drill program.'
On behalf of the board of directors,
Thomas C. Shrake, CEO |
