Target Generation Map — Colorado

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

About Mining in Colorado

Colorado has one of the richest mining histories in North America, with significant gold, silver, and molybdenum production from its Rocky Mountain ranges.

Key minerals: gold, silver, molybdenum, lead, zinc, vanadium. Notable deposits: Climax Molybdenum, Henderson Mine, Cripple Creek, Summitville. Mining districts: San Juan Mountains, Leadville, Teller County, Clear Creek.

The Colorado Division of Reclamation, Mining and Safety administers mineral rights in Colorado. Claim data is accessible through BLM LR2000.

What is a Target Generation Map?

A target generation map integrates multiple datasets — geophysical anomalies, geochemical results, structural features, and historical workings — to visually communicate which areas have the highest exploration priority. These maps are central to project generation pitches and technical program planning.

How to Create a Target Generation Map for Colorado

  1. Import target polygon outlines as GeoJSON
  2. Import anomaly extents as a separate GeoJSON layer
  3. Assign Target Areas and Anomalies roles
  4. Import fault and structure lines
  5. Use Outside Shade on key target polygons to focus attention
  6. Add labels for each named target
  7. Overlay on Satellite basemap to show terrain context
  8. Export at high resolution (3×) for technical presentations

Recommended Settings for Colorado

  • Export format: PNG at 2× for investor presentations, PDF (Letter or A4) for NI 43-101 reports
  • Coordinate system: Ensure source data is in WGS84 (EPSG:4326)

Common Use Cases in Colorado

  • Exploration program planning
  • Investor technical presentations
  • JV partner presentations
  • Staking decisions

Frequently Asked Questions

What file format do I need for Colorado mineral claims data?
Colorado mineral claims boundaries are available from BLM LR2000 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 Colorado?
Mineral claims in Colorado are regulated by the Colorado Division of Reclamation, Mining and Safety. All tenure and claims data can be queried through BLM LR2000.
What minerals are typically mapped in Colorado?
Colorado is known for its gold, silver, molybdenum, lead deposits. Key producing and exploration-stage properties include Climax Molybdenum, Henderson Mine, Cripple Creek. The main mining districts are San Juan Mountains, Leadville, Teller County.
Can I export a Colorado target generation 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.
