Target Generation Map — Ontario

To create a target generation map for Ontario, import your ON 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 Ontario

Ontario is the largest gold producer in Canada and hosts the prolific Abitibi Greenstone Belt, one of the most mineralized geological terranes on Earth.

Key minerals: gold, nickel, copper, zinc, silver, platinum group elements. Notable deposits: Detour Lake, Macassa, Timmins Gold Camp, Sudbury Basin. Mining districts: Timmins-Porcupine, Kirkland Lake, Red Lake, Abitibi Greenstone Belt.

The Ontario Ministry of Mines administers mineral rights in Ontario. Claim data is accessible through Ontario Mineral Lands Administration System (MLAS).

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 Ontario

  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

Frequently Asked Questions

What file format do I need for Ontario mineral claims data?
Ontario mineral claims boundaries are available from Ontario Mineral Lands Administration System (MLAS) 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 Ontario?
Mineral claims in Ontario are regulated by the Ontario Ministry of Mines. All tenure and claims data can be queried through Ontario Mineral Lands Administration System (MLAS).
What minerals are typically mapped in Ontario?
Ontario is known for its gold, nickel, copper, zinc deposits. Key producing and exploration-stage properties include Detour Lake, Macassa, Timmins Gold Camp. The main mining districts are Timmins-Porcupine, Kirkland Lake, Red Lake.
Can I export a Ontario 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.
