The Haimur gold mine is located in the south Eastern Desert, Egypt, about 200 km far from Aswan city and is known as historical mine dated back to (7th–11th centuries). An evidence of ancient mining activities is manifested by excavated quartz veins and old stone tools used for gold extraction. A number of important ancient gold mines in the Allaqi area have, however, received relatively little geological and geophysical attention. Haimur area comprises a variety of Precambrian rocks including igneous and metamorphic units. It is covered by: ophiolite assemblage, metasediments and metavolcanic.

The geophysical measurements are carried out along the ancient mine where the quartz veins are concentered. Several geoelectrical and land magnetic profiles were done perpendicular to the structure of the area, The Electrical Resistivity was acquired by using dipole-dipole configuration of electrode spacing 5, 10 and 15 m of lengths ranging from 160-240 m. In additional to magnetic profiles are applied around old mine. The results indicate that the quartz veins are accomplished with sulfide zones which refer to low resistive zones, high chargeability with moderate to high magnetic anomalies.

Key words: South Eastern Desert, Alter mineralized zone, Land magnetic, Electrical Resistivity and Induced polarization.

    Hello Mahmoud Mekkawi,

    From your presentation, I have two questions regarding your work. 

    1. I see that you have focused on Haimur area, are you going to apply the same procedure on the other four mines?

    2. Do you expect to have similar results on the other areas in Wadi Allaqi?

      I try applying shallow geophysical methds in the economic minerals at Allaqi region, but of course

      every place has its own characterization and some methods are not suitable to other mines.

      For example, at the Abu swayel Cu-Ni ore deposits, the resistivity, chargeability and SP are failed, because, the surface is very resistive and not suitable.
