Abstract:Guilaizhuang gold deposit is the only large new type gold deposit in southwest of Shandong province. In recent years, it has made progress in ore prospecting in the deep part. On the basis of studying geological characteristics and gold mineralization types of Guilaizhuang gold mineralization ore bodies, according to previous geological surveying and engineering data of this deposit, regarding Surpac software as main tool, geological database of deep part deposit in Guilaizhuang gold deposit has been set up for the first time, and three-dimensional visualization geological model has been set up as well. Based on this model, by using Inverse distance weighted method, reserves of deep deposit have been estimated. Then compared with traditional geological block method. It is showed that reserves estimation based on Surpac software is simple and accurate. It can provide the bases for the development of mineral resources.
