Abstract :

Dahaneh Qaleh exploration prospect is located about 300 km southwestern of Mashhad and 50 km northwestern Bardeskan. Geological formation of the area is consists of reginal metamorphic rocks with metamorphed basic-inermediate intrusive rocks (Taknar Formation) and low grade metamorphed subvolcanic intrusive rocks with porphyry texture. 50 stream sediment samples with regard to the geology, alteration, mineralization, diversity and extent of drainages in satellite images, were taken that central and eastern margin of study area was the highest values of elements. Maxzimum value of Au is( 12.3ppb), Ag (97ppb), Cu (87.28ppm), Pb (88.94ppm), Zn (160.3ppm). 36 chip composit samples were taken of mineralized and altered zones so that the highest maxzimum value of Au was (72.7ppb), Ag ( 3596ppb), Cu (6318.61ppm), Pb (1439.42ppm), Zn (5515.5ppm) and related with schist units in eastern half and northeastern areas of study area. These areas can be for the next stages of exploration are recommended.
