Reserve evaluation of Darreh Zereshk copper deposit

Abstract:
      Darreh Zereshk deposit is located on the Yazd - Shiraz main road 60 km south west away from Yazd. Exploration research started with drawing geological map in the scale of 1:2000. The data of the 17 DDH were drilled 30 years ago by a French company, with data from 3 DDH were drilled recently by Kanifaravaran engineering company were considered for research evaluation. Afterwards accurate evaluation of the ore reserve was done by using classic statistical (cross-sectional, polygon, triangle and Surfer package). Finally the average reserve was evaluated 86 million tons with an average grade of %0.369 Cu classified in B class. Evaluation was extended using statistic in cross sectional method. Results showed that reserve can be 87 million ton with an average grade of %0.341 cu.
