Event File
The records in an Event file denote points down holes where something of interest has happened. For example, you may want to show the point where oxidation stops.
A typical Event file is unlike an Assay file in that it does not have From/To intervals. The depth at which an event occurs is recorded in a Depth field.

In addition to a Hole ID field and an Event field, an Event file will usually contain a Symbology field that can be used to display symbols where each event occurs.
