TURKEY - Toronto-based NUINSCO RESOURCES has confirmed the existence of a large porphyry copper system at its Berta project. Anomalous copper occurs over 15 km and down to 1,000 metres below surface, the company says.
Widespread soil and rock sampling was conducted during 2005 prior to a six-hole diamond drilling program comprising 1132.5 metres. A 2-km fence with three drill holes crossed the central portion of the extensive copper anomaly to determine the style and intensity of subsurface copper mineralization. These holes demonstrated the presence of anomalous copper throughout the length of the drill holes within rock displaying extensive stockwork veining, quartz-sericite-pyrite alteration, and remnant potassic alteration. All confirm the presence of a large copper porphyry system.
In the northern portion of the project area, three shallow drill holes were collared to test a 2-km-long east-west gold-in-soil anomaly. One hole was stopped at 40 metres in a fault zone while the other two were completed to 125 and 105 metres. Within a domain of anomalous zinc and copper, fracture-filling quartz veins provide locally elevated gold analyses. The gold is apparently fracture-controlled and associated with sulphide mineralization hosting elevated copper, zinc and lead values over narrow widths.
The Berta property is located approximately 50 km south of the Black Sea in northeastern Turkey. It lies within the prolifically mineralized Pontide Mountains metallogenic belt. The licences encompass a large area of extensively altered and sulphide-mineralized dacite volcanic and intrusive rocks in rugged terrain displaying approximately 1,500 metres of vertical relief. The Berta project is a 50/50 joint venture of Nuinsco (www.Nuinsco.ca) and FALCONBRIDGE (the operator).
