What is a Drill Results Map?
A drill results map plots the collar locations of completed drill holes alongside key assay results — typically highest-grade intercept, hole depth, and azimuth. It is the standard figure included in exploration news releases and is scrutinized by investors and analysts to understand the spatial distribution of mineralization.
