Manipulate drillholes

Having set up the drillhole styles, you can now manipulate the display of the drillholes by:

• displaying cylinders
• displaying lithological codes on the right-hand side
• displaying assays on the left-hand side
• displaying colour-filled bar graphs of the gold assays on the left-hand side and offsetting them by 5m

Note: All of the following tasks require that you are connected to the database surpac_training.ddb.

Task: Display cylinders

You can use display cylinders to view high grade areas. The colour of the cylinder is taken from the styles table, and its size is determined by the numeric value for that field.

1. Choose Display > Drillholes.
2. Select the Rescale view to display all holes in plan view check box, to allow Graphics to resize and display all data after you have applied the changed styles.
3. Clear the Add constraint to holes check box, to display all data in Graphics.
4. Enter the information as shown, and click Apply.



You can get a sense of how the orebody is trending by viewing and rotating the data in Graphics.
