How to Use Datamine Studio 3 for Geological Modeling and Grade Estimation

Datamine Studio 3 is a powerful software for geological modeling and grade estimation. It allows you to create, manipulate and visualize 3D models of mineral deposits, as well as perform various geostatistical analyses and estimations. In this tutorial, you will learn how to use Datamine Studio 3 for some basic tasks, such as creating a project, importing data, defining parameters, estimating grades and generating reports.

Creating a Project

To start using Datamine Studio 3, you need to create a project. A project is a folder that contains all the files and settings related to your modeling and estimation work. To create a project, follow these steps:

• Launch Studio 3 either by clicking its icon on your desktop, or by choosing Start Programs Datamine Studio 3.

• Select Create Project to open the Studio Project Wizard.

• Press Next > to open the Project Properties dialog.

• Type a name for your project in the Name cell. The name will also appear in the Location box.

• Make sure Create Extended precision project and Automatically add files currently in this directory when the Next > is clicked are checked.

• Press Project Settings... button to change the Project Settings if needed. You can specify the coordinate system, units, default file types and other options for your project.

• Press OK to close the Project Settings dialog.

• Press Next > to create the project folder and add any existing files in the current directory to the project.

• Press Finish to close the Studio Project Wizard.

Importing Data

The next step is to import your data into the project. Datamine Studio 3 can handle various types of data, such as drillhole data, surface data, wireframe data, block model data and more. You can import data from different sources, such as Excel spreadsheets, text files, AutoCAD files, ODBC databases and more. In this tutorial, we will focus on importing drillhole data and surface data. To import drillhole data, follow these steps:

• Select File Import Drillhole Data... to open the Drillhole Data Import Wizard.

• Press Next > to open the Data Source dialog.

• Select Excel Spreadsheet as the Data Source Type.

• Browse for the Excel file that contains your drillhole data. You can use the sample file Drillhole Database.xlsx provided with this tutorial.

• Select Collar Sheet as the Sheet Name.

• Press Next > to open the Data Format dialog.

• Select Fixed Column Widths as the Data Format Type.

• Specify the column widths for each field in your drillhole data. You can use the sample values provided with this tutorial.

• Press Next > to open the Field Mapping dialog.

• Map each field in your drillhole data to a corresponding field in Datamine Studio 3. You can use the sample mapping provided with this tutorial.

• Press Next > to open the Output File dialog.

• Type a name for your output file in the Output File cell. The output file will be a Datamine table file (*.dm) that contains your drillhole collar data.

• Press Next > to open the Summary dialog.

• Review the summary of your import settings and press Finish to import your drillhole collar data into your project.

To import your drillhole survey data, repeat the same steps as above, but select Survey Sheet as the Sheet Name in step 5, and type a different name for your output file in step 12. To import your drillhole assay data, repeat the same steps as above, but select Assay Sheet as the Sheet Name in step 5, and type a different name for your output file in step 12. To import surface data, follow these steps:

• Select File Import Surface Data... to open the Surface Data Import Wizard.

• Press Next > to open the Data Source dialog.

• Select AutoCAD 51082c0ec5
