Semi-detailed copper exploration in the Ahmadabad, Hormozgan Province
The Ahmadabad copper deposit is located in the Hormozgan Province, 180 Km away from the NE of Bandar-Abbas. The deposit is one of available copper deposits in the ophiolite melange of the area with old workings. The high amount of slags confirms the considerable exploitation in the past. Lithology of the area belongs to the upper ophiolite zone and includes pillow basalt, radiolarite and pelagic limestone. Lithological contacts are mostly faulted. Ore mineral has occurred as 0.5-5 m wide lenses, 3-50 m long within the radiolarite and pillow basalt layers. Due to oxidation and formation of limonite, goethite and malachite, this zone has yellow to brown color. Pyrite and chalcopyrite exist is some areas.
The result of IP and RS geoelectrical survey shows a highly anomalous zone, 200*250 m with low depth. Three boreholes were drilled totally reaching 248 m. The analysis of samples from cores gave an average copper grade of 1% and maximum 4.5%.
Considering the result of exploration project, in is recommended to do 1:1000 to 1:500 structural-geological studies and complementary geophysical survey in the area for continuing the drilling program.
