GEMS Resource Evaluation When you are ready to conduct a feasibility study, or to create a long-term mine plan, GEMS Resource Evaluation provides the tools that you need. With its full range of block model creation and estimation techniques, this system configuration allows you to quickly and easily assess the economic potential of your deposit. Resource Evaluation Features Geological and grade modelling Block Models Grid models Polygons 3-D Modelling Complete set of grade estimation techniques Volumetrics Whittle Interface Resource Evaluation brochure A4 (194KB) | Letter (194KB) Accurate, Un-biased Modelling Techniques At Gemcom, we understand the importance of accurate, unbiased block models of your ore deposit. That's why we offer the most powerful and flexible geological and grade modelling system available today. Using a variety of methods, from simple polygons to highly sophisticated 3-D solids modelling, GEMS allows you to create the best possible geological model. To model grade values, choose from block models or grid models for the solution that best suits your deposit. Next, take advantage of the complete set of grade estimation methods, such as inverse distance and ordinary or indicator kriging to interpolate multi-element values. You have full control of the interpolation process to account for anisotropy, geological domains and anomalous grade values. Gemcom's unique, volumetric process, known as "needling," gives your project an immediate advantage. Needling differentiates the proportion of each solid as it intersects the blocks of a block model, providing you with weighted tonnage and grade estimates for each rock type. In almost no time at all, you can produce accurate and comprehensive reports of your modelled resource. For open pit design, GEMS also interfaces seamlessly with Gemcom Whittle pit optimisation systems, allowing you to determine the most strategic design for the highest return on your investment. Providing the foundation for this power, GEMS' multiuser open database makes data management and analysis easy and efficient.
