MARCH 2014 • E&MJ; 69 www.e-mj.com O P E R AT I N G S T R AT E G I E S • A variogram autofitting tool capable of handling complex variography, allowing quick and high-quality fitting of multi- variate, multidirectional and multistruc- ture variograms. Isatis Vario Pack also provides tools for the detailed analysis of the transition between geological domains. These tools, described by Geovariances as unique in the marketplace, help characterize the rela- tionships between domains and grades, and analyze the grade behavior at the con- tact between two domains. Mintec Inc., based in Tucson, Arizona, USA, introduced MineSight Reserve, part of its MineSight software platform, in March 2013. Reserve features a new and completely integrated reserves calculation and reporting engine, called the Unified Reserves Engine, or URE throughout MineSight. URE, according to Mintec, supports 3-D block modeling and stratigraphic mod- els and improves the user's ability to clas- sify reserves. Ventyx's MineScape Block Model pro- vides a sophisticated working environment where geologic rules are defined for local geology. The deposit model is built by pro- gressively introducing geologic elements through loading of physical interpreted shapes or interpolation using material associations and/or zone following with a selection of algorithms. The model can be displayed at any time to validate the model construction process. The complet- ed model becomes the base for reserves and other mine planning work, allowing classification of reserves by level, material type, polygon, wireframe and any block model attribute. Carlson Geology, part of Carlson Soft- ware's Mining 2014 package, is designed to allow users to manage drillhole data, plus calculate strata models, block models, quantities and qualities. According to the company, the process from importing drill- holes, validating the data and modeling the ore to reserves calculations is seamless. For drillholes, Carlson Geology enables users to produce accurate models, automate data, turn out reports quickly and easily, differ- entiate by quality and tonnage, and analyze for compliance. The most recent version of Geology provides users with the ability to run Surface Mine Reserves more than three times faster, according to the company. Ottawa, Canada-based software develop- er ThreeDify's Excel CoreBlock, previously known as Excel CoreViz, is a member of the ThreeDify GeoOffice Suite. CoreBlock is a 3-D drillhole data visualizer and a simplified resource estimator deployed as an add-in to Microsoft Excel. CoreBlock consists of two modules that can be licensed separately: • The CoreViz module offers interactive 3-D drillhole data visualization within Micro- soft Excel. • The BlockModel module features a Radial Basis Function (RBF)-based implicit mod- eler. It allows the user to quickly create and export 3-D block models of grades and wireframes (as iso-grade surfaces or solids). The BlockModel module also allows the user to classify resources into measured, indicated and inferred classes. According to the company, CoreBlock was created not just for geologists, but also for other stakeholders, such as investors, fund managers and property owners. CoreBlock-powered Excel worksheets or animation videos exported by CoreBlock can be shared without resorting to other expensive geological modeling packages. ThreeDify GeoOffice Suite is a strategic project that aims to seamlessly integrate ThreeDify mining software solutions into the Microsoft Office workflow to increase user productivity.
