Abstract:

    To investigate the evolutions of deposit regularity, reserve and mineral grade of Sareke copper mine during mining，software DIMINE was introduced to establish the three dimensional geological models and reserve estimations. The results showed that DIMINE successfully and precisely realized the visualization of surface model，deposit models and underground engineering. The metallogenetic zones were divided to five deposits according to stratiform spatial locations. The reserve reached to 16. 066 million tons in the altitude range of 2 790 m and 2 600 m，and the average copper grade was 1 .08 %. Additionally, the reserve estimations by DIMINE were consistent with the results verified by drilling engineering.

Key words: three dimensional geological modeling, digital deposit models, reserve estimation, drilling verification
