Collar File
The Collar file contains the location, in Northing, Easting, and Z coordinates of each drillhole collar. The collar file also contains the hole name, total depth and, optionally, the inclination and azimuth of the hole at the collar. Additional information such as Prospect and Drill Date may also be included.
If survey information is not provided in the Collar or Survey file, the holes are assumed to be vertical.
