This paper analyzes the global distribution and development of lead-zinc resources, aiming at intensifying China's mining companies' core competitiveness, based on their resource distribution and development in major countries and lists the main lead-zinc mines globally with large reserves. This paper, based on the world lead-zinc import & export and China's investment environment, presents suggestions for Chinese mining companies on prioritizing countries with favorable geology for lead-zinc mineralization, considering investment environment, using other countries' resource to set up Chinese lead-zinc industrial base, forming new mining development concept and mode so as to promote the sustainable development of Chinese capital, and to help Chinese mining companies out of the mining economy predicament.

This paper uses mine 3D software to establish the 3D geological model of Dasuji Molybdenum deposit, and applies geostatistics to estimate the reserve and resource, offering references for next exploration and mining. MicroMine is used to set up geological database of Dasuji molybdenum deposit, topographical DTM, ore body model and grade model, 3D of drilling database, also shows the spatial position of morphology of ore bodies in reality. Based on geostatistics, drilling samples are composited and statistically analyzed. Grade and reserve is estimated on the basis of ordinary krigging. Compared to the traditional block and mine
'
s production, this 3D software gives reliable estimation, which provides references for dynamic management of mine
'
s resource.
