Event file

An event denotes a point down a drillhole where something of interest has happened. For example, you may want to show the point where oxidation stops. Events can be displayed with colour coded labels. You can also display symbols where each event occurs.

A typical Event file is shown in the illustration. Notice that it is unlike an Assay file in that it does not have From/To intervals. The depth at which an event occurs is recorded in the Depth field.

Hole ID

A Hole ID field containing an identifier for each drillhole.

Depth

The depth at which the event occurs.

You can use an Assay file as an Event file if you use either the From or To intervals to define the depth of an event.
