Coiron project plans Rock Resources Inc RKR Shares issued 14,424,750 Feb 20 close $0.38 Mon 23 Feb 98 News Release Mr Thomas Kennedy reports Rock's management and geological team travelled to Chile for the first week of February 1998. The purpose of this trip was to meet with the management team and geological team of its Chilean counterparts with respect to the current exploration activities on the Coiron project. Both the Canadian team and the Chilean team travelled to the Coiron project on February 5 1998. A majority of the road work was completed at that time. The representatives of Compania de Exploraciones Mineras Los Lobos SA (the Chilean company completing the road work) have advised Rock that the road work should be completed in approximately two to three weeks. The road has taken slightly longer than was originally anticipated due to necessary blasting. Once Rock has been advised of road completion Rock will be in a position to announce the drill program commencement date. After a thorough review of all current geological evidence the two geological teams have determined the first drill targets. Road building on an exploration project can turn up valuable geological evidence (not unlike a planned trenching program). During its site visit the Rock team observed a mineralized showing exposed by the road construction. Rock's independent consulting geologist, Mr John Ostler, sampled this showing while the team was in Chile and his letter report to the company dated February 19 1998 states: Re. New Showing of Copper Mineralization in Granodiorite on Cerro Carmen, Coiron Property, Region IV, Chile, January 1998: A new showing of copper mineralization was opened on the upper slope of Cerro Carmen during road construction. The showing is exposed in a road cut about 12m long above the old mill site and near an old production pit. The style of alteration and mineralization of this showing is commonly encountered in association with large hydrothermal systems and porphyry copper deposits. The host rock is Late Cretaccous-age granodiorite that has been pervasively fractured and altered by large quantities of hydrothermal fluid. Alteration minerals include chlorite, red-brown biotite, and redistributed quartz and feldspar. The copper-bearing minerals - chalcopyrite, chalcocite - are finely disseminated throughout the rock and are accompanied by pyrite. Malachite, a secondary copper carbonate, is common in late fractures tinting them a light green colour. A composite chip sample from this mineralization that was analyzed at Chemex Labs returned metal concentrations that are quite similar to those which constitute the ore body of Cambior's El Pachon deposit northeast of Rock's Coiron property on the same regional trend. Those metal concentrations were as follows: Cu Au Au Ag Ag % g/t oz/t g/t oz/t Cerro Carmen (on the Coiron property) 0.55 0.13 0.0040 2.20 0.064 El Pachon Deposit 0.62 0.02 0.0006 2.41 0.070 At present, the mineralization on Cerro Carmen is almost unexplored; the overall grade and extent of this mineralization is yet known. Comparisons with the grades of porphyry copper deposits in the surrounding area remain tentative until more sampling has been done at Cerro Carmen. This new discovery is in the northeastern part of the Coiron property about 4km northeast of the main porphyry-copper target currently being explored. Presently, it is not known whether the newly discovered copper mineralization is related to the same hydrothermal system that produced the breccia and copper-bearing structures in the central part of the property, or if it is an expression of another system in the northeastern part of the property. Either way, this new copper showing greatly increases the known exploration potential of this area. Sounds Promising. Here's to a successful drill program.
