Abstract:

This paper presents new results about evaluating the exploration's reliability and Uranium reserve calculation of the Binh Duong deposit, Cao Bang province, by using the multiple math statistical and geostatistics methods. The results indicte: - The Uranium ore bodies in the Binh Duong deposit are lenticular-shaped, complex morphology and structure. They belong to the small-scale type, with complex changes. - The Uranium contents of industrial ore bodies calculated by the ore thickness’ weighted average method are comparable to those estimated by the adjacent bulk method. However, these values are systematically lower than the mean values. - The crucial factor in the reliability of the exploration and calculation for reserves in the Binh Duong Uranium deposit are the ore bodies’ thickness and random error in sample analysis. - The error in calculating uranium reserves in the case of taking into account the efficiency of using the internally and externally extrapolating boundaries of the ore body are larger than the case without paying attention to this efficiency. - The exploration network has been carried out being within 40m along the strike and 20÷40 m along the slope, enough basis to calculate reserves at level 122; however, out of this network only responds to the requirement of calculating resource at level 333.
