Chile, Coiron Property, Three Economic Targets Established
ROCK RESOURCES INC ("RKR-V;RORSF-L")
- Chile, Coiron Property, Three Economic Targets Established
Rock Resources Inc. President, Tom Kennedy, stated "1999 will be a banner year for Rock Resources given the
well-evidenced World-Class Discovery potential of our main economic target in Chile."
1 - MAIN TARGET - Mount Tacho Hydrothermal System
John Ostler, M.Sc., P.Geo., Rock Resourcess Independent Consulting Geologist, in his March 31, 1999 report
states in part as follows: ".....The Mount Tacho hydrothermal system on the Coirn Property closely resembles
Sillitoe's (1993) type-description of a gold-rich porphyry copper deposit. It conforms to all five of the geological
attributes that are almost required in the model, those relating to coeval volcanics, alteration, magnetite-hematite
deposition and stockwork vein development. Also, it can be classified within a significant category with regard to
the four attributes they vary significantly among the 29 porphyry deposits that were studied by Sillitoe, those
relating to: age, geological setting and chemistry of the host intrusion..... .....Geological mapping, geochemical
sampling, preliminary drilling and geophysical surveys conducted over the Mount Tacho hydrothermal system all
contribute to the conclusion that this system could host a substantial gold-rich porphyry copper deposit. The
shape of the system on surface, its alteration pattern and geophysical signature indicate that bodies of economic
mineralization could occur anywhere around the margin of the hydrothermal implosion breccia..... .....I recommend
that this target be given the highest exploration priority and that a program of extensive drilling be conducted over
the whole Mount Tacho hydrothermal system....."
2 - SECOND TARGET - Cerro Carmen
In January 1998 during construction of the 28 km road to access the main target area a new showing of copper,
gold and silver mineralization was exposed. Analysis returned metal concentrations that are quite similar to those
which constitute the ore body of Cambior's El Pachon deposit located on the same regional trend. Disseminated
copper mineralization on Cerro Carmen is the second most important economic target on the Coirn property at
present.
3 - THIRD TARGET - Southern Gold Zone
In May 1998 a further new discovery of a gold-bearing fault breccia that extends over 10,500 sq. metres on surface
was made (a 50 chip sample showed 0.20 oz/ton gold and significant silver). The southern gold zone comprises the
third most important economic target currently recognized on the Coirn property.
MAJORS ON SITE:
At present, our consulting geologist is in Chile hosting inspections of the Coirn property by several major mining
companies.
Summary
In the Rock Resources news release of June 5, 1997 the management of Rock Resources expressed the belief that
our Chilean project could host a Potential Billion Tonne Copper Porphyry Deposit. Given our continuing
exploration success over the past two years (in particular, the results of the recent IP and MAG surveys) we are
now of the belief that the Mount Tacho Hydrothermal System (the main target) is large enough to host a
world-class porphyry gold-copper deposit similar to those at Los Pelambres and El Pachon located northeast of
the property-area.
