Geosoft Target is an essential software extension for Oasis montaj. It is widely used by geologists, geophysicists, and exploration teams to visualize, analyze, and manage subsurface drillhole data. Whether you are mapping a new mineral deposit or creating complex 3D models, mastering Target is crucial for making data-driven exploration decisions.
The first step in any Geosoft Target workflow is the creation of a Project (*.gpf) file
Plot assay bars or lithology colors next to the drillhole stem.
He remembered the "Updated" file attachment. He opened it with a hex editor, bypassing the PDF reader. At the end of the file, after the EOF marker, was a string of binary code. geosoft target tutorial pdf updated
It wasn't the version number that stopped him. It was the timestamp. The file had been modified three minutes ago, in a secure server that hadn't been online since the collapse of the '08 mining bubble.

He opened his own copy of Target. He didn't have the Yucca Flat data, but he had a dataset from a failed copper prospect in Chile—a project that had cost his company millions and yielded nothing but frustration. He decided to run the "Updated" tutorial workflow on his dead data. Geosoft Target is an essential software extension for
Contains data tied to a specific point depth rather than an interval. The Import Workflow Navigate to . Select your data source (Excel or CSV Text files).

A: Yes, the 2025 edition has an appendix (Appendix D) specifically for the Geosoft for ArcGIS Pro extension, covering the new Borehole Geologist Ribbon . The first step in any Geosoft Target workflow
Before launching the software, you must organize your data into clean spreadsheet formats (CSV, XLSX, or TXT). A standard Geosoft Target project requires four primary data tables: Collar Table Defines the surface starting point of each drillhole. Hole_ID : Unique name or number of the drillhole. X or Easting : East-west coordinate. Y or Northing : North-south coordinate. Z or Elevation : Height above sea level. Total_Depth : The final length of the hole. Survey Table Tracks the path of the drillhole beneath the surface. Hole_ID : Matches the collar table exactly.
Set the project Coordinate System by navigating to > Set Project Coordinate System .
Combine surface geochemistry, geophysics, and drillhole data.
