Holes 57,58, and 59 are in the pyritic shell which commonly surrounds mineralized porphyries and they define the eastern boundary of the system. The north, south and west directions are still open and will be located by continued drilling. Note high rhenium associated with high molybdenum content in CQ-56.
All analyses were carried out at ALS Patagonia Laboratories, Coquimbo, Chile.
Tor Bruland, MSc, PGeo is the qualified person under National Instrument 43-101 in charge of the program. The results should be considered preliminary exploration data.
Copaquire is located in northern Chile on the west fissure which hosts some of the largest copper-molybdenum porphyry mines in the world. It is the last well-exposed major porphyry system in Chile yet to be fully explored. The company has an option to purchase a 100 per cent interest in the property.
