Drill Results Map — Alaska

To create a drill results map for Alaska, import your AK claims or data as GeoJSON, assign the appropriate layer role for automatic styling, set the Light or Satellite basemap, and export as PNG or PDF. The entire process takes 15–30 minutes with no GIS experience required.

About Mining in Alaska

Alaska hosts some of the largest undeveloped mineral deposits in the world, including Donlin Gold and Pebble, alongside active gold, zinc, and copper producers.

Key minerals: gold, copper, zinc, silver, coal, platinum. Notable deposits: Pebble, Fort Knox, Donlin Gold, Greens Creek, Red Dog. Mining districts: Fairbanks, Juneau, Nome, Seward Peninsula.

The Alaska Department of Natural Resources administers mineral rights in Alaska. Claim data is accessible through Alaska DNR Online Mapping.

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 Alaska

  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

Frequently Asked Questions

What file format do I need for Alaska mineral claims data?
Alaska mineral claims boundaries are available from Alaska DNR Online Mapping and can typically be downloaded as Shapefiles or KML. Convert these to GeoJSON at mapshaper.org before importing into Exploration Maps.
Who regulates mineral claims in Alaska?
Mineral claims in Alaska are regulated by the Alaska Department of Natural Resources. All tenure and claims data can be queried through Alaska DNR Online Mapping.
What minerals are typically mapped in Alaska?
Alaska is known for its gold, copper, zinc, silver deposits. Key producing and exploration-stage properties include Pebble, Fort Knox, Donlin Gold. The main mining districts are Fairbanks, Juneau, Nome.
Can I export a Alaska drill results map for an NI 43-101 report?
Yes. Exploration Maps exports PNG and PDF at 2–3× pixel ratio, suitable for inclusion in NI 43-101 technical reports as required figures. The export includes north arrow, scale bar, legend, and title block — all elements required for NI 43-101 compliance.
