Drill Results Map — Wyoming

Wyoming — the largest US coal producer and a key state for uranium exploration and trona mining — is a prime target for junior exploration companies. Here's how to create a professional drill results map using Exploration Maps in 15–30 minutes.

Example drill results map created in Exploration Maps — Example drill results map exported from Exploration Maps — style your Wyoming data the same way.

About Mining in Wyoming

Wyoming is the largest coal-producing state in the United States and hosts major trona and uranium deposits, with growing gold exploration in its mountain ranges.

Key minerals: coal, trona, uranium, gold, bentonite. Notable deposits: Powder River Basin Coal, Green River Trona, Gas Hills Uranium. Mining districts: Powder River Basin, Green River Basin, Sweetwater.

The Bureau of Land Management (BLM) administers mineral rights in Wyoming. Claim data is accessible through BLM MLRS (Mineral & Land Records System).

Getting Mining Data for Wyoming

Portal	Formats	Notes
BLM MLRS (Mineral & Land Records System)	MLRS reports + map viewer (claims by legal description)	Wyoming BLM hardrock mining claims use UTM Zone 13N (EPSG:32613). Powder River Basin coal leases are managed separately through BLM's coal leasing program and are not in MLRS — contact the BLM Wyoming State Office for coal lease spatial data.

How to Create a Drill Results Map for Wyoming

For a full step-by-step guide to drill results maps, see How to Make a Drill Results Map.

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

Labelling a drillhole with its best intercept in Exploration Maps.

Tip for Wyoming: Wyoming uranium in-situ recovery (ISR) properties use a network of widely-spaced wellfields — show production wells and monitoring wells as distinct point symbol layers, and add a polygon outline of the licensed wellfield boundary area so the full project footprint is clear to regulatory reviewers.

Frequently Asked Questions

What file format do I need for Wyoming mineral claims data?

Wyoming mineral claims boundaries are available from BLM MLRS (Mineral & Land Records System) 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 Wyoming?

Mineral claims in Wyoming are regulated by the Bureau of Land Management (BLM). All tenure and claims data can be queried through BLM MLRS (Mineral & Land Records System).

What minerals are typically mapped in Wyoming?

Wyoming is known for its coal, trona, uranium, gold deposits. Key producing and exploration-stage properties include Powder River Basin Coal, Green River Trona, Gas Hills Uranium. The main mining districts are Powder River Basin, Green River Basin, Sweetwater.

Can I export a Wyoming drill results map for a 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 standard map elements required for NI 43-101 compliance.
