Application of Modeling and reserve evaluation of Dali porphyry copper gold deposit using concentration volume fractal method Markazi province Mohammad Rashid hamidi Rashidhamidi2010@yahoo com Date of Submission 2014 01 23 Department of Mining Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Ahmadreza Mokhtari ar mokhtari@cc iut ac ir Supervisor Houshang asadi hooshang@cc iut ac ir AbstractCopper gold porphyry deposit of Dali is located 40Km the north west of Delijan city andthe access way is located between Tehran Esfahan high way and Arak way In order to studythis copper gold porphyry deposit 6 borehole and 1928 lithogeochemical sample was used Estimation method for modeling of deposit is inverse distance Anisotropic By usingFractal C V method over data which are result from estimator delineation ofmineralization zones were done and C V fractal algorithm is applied on these models ForCu algorithm separated 4 zones and three threshold and for Au algorithm separated 4zone and three threshold too Lithology model for deposit was designed Base rocks of Cu Au mineralization are Quarts diorite porphyry Based on ore deposit estimation results Cuore estimation for grade threshold 1000 ppm and 2 5 gr ton density was 13 million toneand average grade for this threshold was 3797 ppm Total Au ore estimation fore gradethreshold 0 126 ppm and 2 5 gr ton density was 12 million and 490 thousand and averagegrade for this threshold was 0 487 ppm Keywords Concentration volume C V fractal model Separation of mineralizationzones Porphyry deposit Modeling Dali
