Abstract:

The metallogenic geologic body volume method is a resource appraisal method based on varied comprehensive geological informations of known ore deposit model. The algorithm is: the calculated mineral resources=minimum appraisal area×dip extension×area parameters of the ore-bearing geological body×similarity coefficient×ore-bearing coefficient of the model area. The obvious advantage of this method is that it quotes resource quantity of large known deposits as a guideline of resource quantity in the deep and periphery portions of the ore-bearing gological bodies in the appraisal area, thus greatly improving the accuracy of ore-bearing coefficients in model zone, and making the appraisal  result more reasonable and reliable.Taking the potential evaluation of a copper mine in Dexing area,Jiangxi as an example, the authors elaborate the application process of metallogenic geologic body volume method. 7 671 100 t of potential copper resource is estimated for above 2 000 m level.
