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.

How to Create a Drill Results Map for Colorado

  1. Import your drill collar CSV (columns: hole ID, latitude, longitude, depth, assay)
  2. Assign the Drillholes layer role
  3. Import the property claims boundary as GeoJSON
  4. Add callout labels to key holes showing hole ID and best intercept
  5. Use Badge Label type to highlight the highest-grade holes
  6. Configure the title with program name and date
  7. Set the Landscape 16:9 ratio for news release figures
  8. Export as PNG at 2× for email and PDF for the news release attachment
