   Abstract
   The current report presents the result of reassessment of geochemical data of the Partak and Mahrud in the southeast of Birjand, under a contract between the GSI and Madanafarin Consulting Engineers at 1999.
   At the first step, by applying various processing methods, geochemical data was analyzed, and the result of the BRGM geochemical survey at 1976 was complied with hammer prospection data. In the next step, remote sensing data and mineral indication data, such as Shurak indication and Maldar chromite were used for controlling and taking complementary samples. This part of study was done by GSI.
   The second step includes field visitation and controlling the anomalous zones. Geochemical and heavy mineral sampling was done in a high density network. Petrography and microscopic studies also were conducted. 1:10000 topography and geology maps were prepared for the anomalous areas.
   In the third step, the deposit and type of mineralization were determined based on interpretation of geochemical data. A copper mineralization was identified in the Shurak area that is 3*1.6 Km, located 10 Km away from SW of Purang. Sampling was done by stream sediment method in the area that was 31 Km2. mineralization has occurred as a Ni-Cu stratibound deposit in the mafic-ultramafic rocks similar to Style Water deposit. Major elements include Cu, Zn, Ag and Au.
   The polymetal Bagh-e Sangi deposit is 1.2*1.8 Km, located 7 Km away from NE of the similar village. Sampling was done in a network with 50 m gird. This deposit is a skarn type mineralization that is similar to the Corsay mine and includes Ag, Cu, Zn and Co metals. Both zones are recommended for further studies.
   There are several smaller anomalous zones including Kanif, Kalate Rashid, Maldar, Mehdinazhad, and Golab listvenite that contains chromite mineralization.
